I started this entry with a discussion about keeping up to date with language and framework changes, but it became longer than intended so I decided to move it to a separate post below. This example ties into what was discussed there. I’m hoping to add random posts over the months with lots of examples like this.*

Before the .NET Framework 2.0 was released, if you wanted to pass custom information through to an event handler when an event was fired,  a delegate needed to be declared that specified a class that was derived from System.EventArgs.  Framework 2.0 introduced the generic System.EventHandler delegate, which allows any class derived from EventArgs to be used with the event handler, making it much easier (and cleaner) to pass arbitrary data through to an event handler.

This example uses a MessageMaker class that has the generic event MessageMade. The MessageEventArgs class has a property for the Message itself as well as one for a Priority, the idea being that the MessageMaker could create both prioritised messages as well as plain messages with no notion of importance.

public enum MessagePriority
{
     Low,
     Moderate,
     High
}

The MessageEventArgs class made slightly cleaner with C#3 Automatic Properties:

public class MessageEventArgs : EventArgs
{
     public string Message { get; set; }
     public MessagePriority MessagePriority { get; set; }

     public MessageEventArgs(string message)
     {
          Message = message;
     }

     public MessageEventArgs(string message, MessagePriority messagePriority)
    {
         Message = message;
         MessagePriority = messagePriority;
     }
}

The MessageMaker, with the generic event:

public class MessageMaker
{
      public event EventHandler<MessageEventArgs> MessageMade;

      protected virtual void OnMessageMade(MessageEventArgs mea)
     {
         if (MessageMade != null)
             MessageMade(this, mea);
     }

     public void SimulateMessageCreation(MessageEventArgs mea)
     {
          OnMessageMade(mea);
     }
}

and the MessageMonitor whose event handler watches for the events:

public class MessageMonitor
{
   public MessageMonitor(MessageMaker messageMaker)
   {
         messageMaker.MessageMade += new EventHandler(MessageProcessor);
   }

   void MessageProcessor(object sender, MessageEventArgs mea)
   {
      if (mea.MessagePriority != null)
      {
           Console.WriteLine("Prioritised message detected");
           Console.WriteLine(string.Format("Message:{0}, priority:{1}", mea.Message,
                                            mea.MessagePriority));
       }
      else
      {
           Console.WriteLine("Regular message detected..");
           Console.WriteLine(mea.Message);
       }
   }
}

class Program
{
   static void Main(string[] args)
   {
        MessageMaker messageMaker = new MessageMaker();
        MessageMonitor messageMonitor = new MessageMonitor(messageMaker);
        messageMaker.SimulateMessageCreation(new MessageEventArgs( "Many more margaritas",
                                                                    MessagePriority.Moderate));
       System.Console.ReadLine();
    }

The main point here is that no delegate needs to be declared, and we can inspect the properties in the MessageEventArgs class within the event handler to examine this (arbitrary) information, and act accordingly.

* The MSDN samples are often very good, but every now and then a bit lacking.  I like to write snippets and my own examples even when the provided ones are clear, as things seem to hang around longer when done that way.  Examples on this blog shouldn’t be interpreted as an indication of my opinion about the quality of the MSDN samples related to the topic in question.

Seguimos con el .Net Framework 2.0…

Leccion 2: Usando Tipos Por Referencia Comunes

La mayoría de los tipos del .Net Framework son tipos por referencia. Los tipos por referencia proveen gran flexibilidad y excelente rendimiento cuando son pasados como argumentos de métodos.

Que es un tipo por referencia (reference type)?

Los tipos por referencia almacenan la dirección de sus datos, también se conocen como punteros, sobre el stack. Los datos actuales de estas referencias son almacenados en un área de la memoria llamado el heap. El runtime administra la memoria usada por el heap a través de un proceso llamado el garbage collection. El garbage collection recupera la memoria periódicamente cuando se necesite, disponiendo de los ítems que llevan tiempo sin ser referenciados. El garbage collection ocurre solo cuando se necesita o es lanzado por la llamada a GC.Collect. Automaticamente el garbage collection esta optimizado para aquellas aplicaciones en donde la mayoría de las instancias son de vida corta, excepto para aquellas ubicadas al inicio de la aplicación.

Comparando el comportamiento entre value types y refence types

Los reference types representan una dirección del dato en lugar del dato en si mismo. Al asignar una variable value type a otra, se crea una nueva copia del dato en el stack de la memoria, en cambio, asignar una variable reference type a otra, solo crea una segunda copia de la referencia, ambas apuntando a la misma dirección de memoria. Cuando se modica una copia de una variable value type, solo esta se ve afectada (todas las copias pueden tener valores distinto). Cuando se modifica una copia de una variable reference type, todas sus copias se ven afectas (todas las copias apuntan a la misma dirección de memoria y todas modifican el mismos valor, todas tienen el mismo valor).

Built-in reference types

Hay alrededor de 2500 built-in reference types en el .Net Framework, todo lo que no derive de System.ValueType es un reference type. La siguiente tabla muestra los más comunes:

Tabla 1-2 Refence Types Comunes

Reference Types

String y StringBuilder

Los strings de System.String son inmutables en .Net. Esto quiere decir que ningún cambio a un string causa que el runtime cree un nuevo string y abandone el viejo, en código:

string s = “hola”; //crea hola

s += “ john”//matiene el anterior en memoria y crea uno nuevo: hola John; es decir hay ahora dos strings en memoria.

Solo el último string tiene una referencia, los otros serán puestos a disposición del garbage collection. Esto genera un uso excesivo del garbage collection y perjudica el desempeño de la aplicación. Hay varias formas de solucionarlo:

· Use los métodos Concat, Join o Format de la clase String para unir varias cadenas en una sola.

· Use la clase StringBuilder strings dinámicos (mutables).

Usar la clase StringBuilder es la solución más flexible ya que esta puede abarcar varias cadenas. El constructor por defecto crea un buffer long de 16 Bytes, el cual crece según sea necesario.

Como crear y ordenar arrays

La clase encargada del manejo de los arrays es System.Array.

Int[] miArray = {1, 3, 2};//declarando e inicializando un array

Array.sort(miArray);//ordenando un array

Como usar Streams

Permiten leer y escribir en disco y comunicarse a través de la red. La clase encargada del manejo de las tareas específicas de streams es System.IO.Stream. Los network streams se encuentran en System.Network.Sockets y los encrypted streams se encuentran en System.Security.Criptography.

Tabla 1-3 Tipos streams comunes

Tipos Stream

StreamWriter file = new StreamWriter(“text.txt”);//crear y escribir en un archive de texto

file.WritreLine(“Hola Mundo”);//escribir en el archivo de texto

file.Close();//cerrar el archivo

StreamReader file = new StramReader(“text.txt”);//abre el archivo

Console.WriteLine(file.ReadToEnd());//lee el archivo de principio a fin y lo imprime

file.Close();//cerrar el archivo

Como lanzar y capturar excepciones

Las excepciones son eventos inesperados que interrumpen la ejecución normal de un assembly. El .Net framework incluye varias clases que me permiten manejar errores, la más común es la clase Exception que contiene un mensaje de error, otras que describen diferente tipos de eventos derivan de System.SystemException y las definidas por el usuario derivan de System.ApplicationException. El runtime solo ejecuta un bloque catch, el que haga juego con la primera excepción. Es recomendable organizar los bloques catch del más específico al menos específico (filtrado de excepciones). Es muy útil utilizar el bloque finally para realizar tareas que se necesitan hacer ya sea que ocurra o no una excepción, ya que independientemente de que ocurra o no una excepción, todo lo que este dentro de este bloque será ejecutado. Aunque el manejo de excepciones cuesta un poco en el desempeño de la aplicación, facilita enormemente el debugging y mejora la experiencia de usuario.

Para iniciar, comenzaré con una serie de post acerca del .Net Framework 2.0, basado en el libro para certificacion del .Net Framework 2.0. Espero les sea de ayuda.

Capítulo 1

Fundamentos del Framework

Leccion 1: Usando Value Types

En el .Net Framework 2.0 hay dos tipos de datos esenciales, los tipos por valor (value types) y los tipos por referencia (reference types). Los tipos por valor son variables que contienen sus datos directamente en lugar de tener una referencia a ellos, lo que ofrece un excelente desempeño. Estos datos son almacenados en un área de la memoria llamado stack en donde el runtime puede crear, leer, actualizar y remover los datos rápidamente con un mínimo esfuerzo. Los tipos de datos numeric y boolean son primeramente los más elementales del .Net Framework 2.0 y son tipos por valor.

Los tipos por referencia son variables que tienen una referencia a una posición de memoria en donde está el valor de dicha variable.

Existen en general 3 tipos de “value types”: Built-in types (tipos propios del lenguaje), User-defined types (definidos por el usuario) y Enumeration (enumeraciones). Cada uno de esto tipos de deto derivan del tipo base System.Value.

Built-in value types

Son tipos base proporcionados por el .Net Framework, con ellos es posible crear otros tipos de datos. Todos los tipos numéricos built-in son tipos por valor. A continuación se da un lista de los tipos numéricos built-in más comunes:

Tabla 1-1 Built-in Values Types

Hay aproximadamente unos 300 value types mas en el .Net Framework, algunos de estos tipos de datos son usados con mucha frecuencia, debido a ello, VB y C# hacen uso de los alias para definirlos.

Cuando se asignan valores entre variables value types, el dato es copiado de una variable a la otra y almacenada en dos posiciones diferentes del stack. Aunque los values types representan variables simples, ellos son objetos y pueden llamar métodos, por ejemplo ToString(), el cual es sobrescrito de System.Object. En el .Net Framework, todos los tipos derivan de System.Object, lo que ayuda a establecer un sistema de tipo común a través del .Net Framework.

Para mejorar el rendimiento con los built-types se recomienda usar los tipos enteros de 32 bits (Int32 y UInt32) para contadores y otras variables enteras frecuentemente accedidas, ya que el runtime optimiza el rendimiento para estos tipos de datos. Para los tipos de dato flotante se recomienda utilizar el tipo Double, debido a que las operaciones con este tipo de dato son optimizadas por el hardware.

Como declarar value types

Los value types tienen un constructor implícito, lo que evita crear instancias con la palabra reservada new como con las clases. Este constructor por defecto asigna un valor de 0 o null a la variable. A pesar de ello, es recomendable inicializar siempre las variables en la declaración. Ejemplo:

bool bandera = false;

En ocasiones es necesario asignar el valor null a una variables, por ejemplo en un formulario, en una pregunta se puede responder si, no, o dejar sin responder, en estos casos es útil utilizar las variables nulas. Ejemplo:

Nullable<bool> bandera = null; //bandera puede tomar el valor de true, false o null

bool? bandera = null; //notación corta

Declarar un variable Nullable habilita los miembros HasValue y Value. HasValue sirve para detectar se ha o no fijado un valor. Ejemplo:

If( bandera.HasValue )

Console.WriteLine(“bandera = ”, bandera.Value);

else

Console.WriteLine(“No se ha asignado un valor a bandera”);

Como crear tipos definidos por el usuario

También llamados estructuras. Al igual que los values types, estos también son almacenados en el stack y contienen sus datos directamente. Las estructuras se comportan casi igual que las clases. Una estructura es una composición de otros tipos de datos agrupados lógicamente para formar un nuevo tipo de dato. Ejemplo:

struct Circulo {

int x;//campos privadas

int y;

int radio;

//constructor

public Circulo(int x, int y, int radio ) {

x = 0;

y = 0;

radio = 0;

}

//propiedades, métodos y operaciones…

}

Para hacer una instancia:

Circulo miCirculo = Circulo new (1, 10);

Si se quiere cambiar la estructura Circulo a un tipo por referencia, basta solo con cambiar la palabra reservada struct por class. De esta forma a las instancias de Circulo se les asignará espacio en el heap, y de una asignación entre dos variables resultaría que las dos variables estén apuntando a la misma instancia.

Las estructuras suelen ser más eficiente que las clases. Se debería usar una estructura en vez de una clase, si el tipo se desempeña mejor como un value type que como un reference type. Una estructura debería cumplir los siguientes criterios:

· Lógicamente representan un único valor.

· Tienen un tamaño menor a 16 bytes.

· No será cambiada después de creada.

· No hará un casting a un tipo por referencia.

Todos los value types en el .Net Framework son de 16 Bytes o short.

Como crear enumeraciones

Las enumeraciones son símbolos relacionados que tienen valores fijos. Use enumeraciones para proporcionar una lista de opciones. El propósito de las enumeraciones es simplificar el código y mejorar la legibilidad habilitando que se usen símbolos significativos en lugar de simples valores numéricos. Úselos cuando tenga una lista limitada de opciones. Ejemplo:

enum Genero : int {Masculino, Femenino} ; //Visual Studio desplegara esta lista cuando los desarrolladores la necesiten

Genero MyGenero = Genero.Masculino; //Es mucho mejor MyGenero = Masculino, que MyGenero = 1;

I’ve decided to start studying for the 70-536 certification exam. I have the exam study guide book, which is currently serving as a great door stop considering it weighs 25 pounds. Am curious as to other people’s experiences with this exam and if they have any suggestions for studying. I started studying for it before and was scoring around 80-90% on the practice exams, but am not sure how realistic they are with the actual exam. Any insight, experiences or advice would be greatly appreciated!

Thank you.

Generics are features that have been introduced to .NET Framework 2.0. Using them you can implement classes and structures in generally way, it mean that a unique class or structure can work with any type. This type is defined in the instantiation’s object, passed as a parameter. The result is a type-safe class that can be used with any type.

Let’s see an example.

First of all, we’re going to define our Generics class

As we can see, our class has a parameter called Type, where it is used on it internal attributes.

Now we’re going to create a simple class, it will be used in our small application.

Finally, we’re going to implement the main method that work with our objects.

As you can see, we created a class named “Item” that has a parameter called Type, and then we instantiated it with different kind of objects. Notice that we can use it with value types and reference types, and it will work in the same way.

See you!

.Net Framework 3.5 in ASP.NET 3.5 are integrate with a powerful ASP.NET Ajax functions.

.NET 3.5 now includes built-in support for all ASP.NET AJAX 1.0 features.

Users can now use Visual Studio 2008 to target both existing ASP.NET applications built with ASP.NET AJAX 1.0, as well as target the new version of ASP.NET AJAX built-into .NET 3.5.

Facts about .NET 3.5 Framework with ASP.NET AJAX:
ASP.NET AJAX 1.0 built as a separate download so that users can install AJAX directly on ASP.NET 2.0. The good news is, with the latest .NET Framework 3.5, all of the ASP.NET AJAX has been build in with ASP.NET, users are not require to install the ASP.NET AJAX separately when testing or deploying the applications.

Another good things is that when user create a new ASP.NET application or web applications with Visual Studio 2008 that uses the .NET 3.5 framework, Visual Studio 2008 will automatically add the AJAX registrations within the applications.

Setting for ASP.NET AJAX 1.0 to Use with ASP.NET AJAX 3.5:
Users who use Visual Studio 2008 to open an existing ASP.NET 2.0 application that uses ASP.NET AJAX 1.0, he / she able to choose to upgrade the application to use .NET 3.5 (and the version of ASP.NET AJAX included within it). Upgrading an ASP.NET AJAX 1.0 application to .NET 3.5 does not require any amendment of the application code, and will be able to complete within minutes.

For more information about ASP.NET Ajax hosting, ASP.NET 3.5 hosting / .NET Framework 3.5 hosting, please log on to http://www.seekdotnet.com or contact SeekDotNet.com at http://seekdotnet.com/contactus.aspx.

ASP.NET 3.5 features has been upgraded from the previous version, these are some of the major updates:

List View:
The ListView control is quiet flexible and contains features of the Gridview, Datagrid, Repeater and similar list controls available in ASP.NET 2.0. It provides the ability to insert, delete, page (using Data Pager), sort and edit data. Users can have great amount of flexibility over the markup generated and complete control on how the data is to be displayed.

Data Pager:
Data Pager provide users with a easier way of paging with the controls. Currently only List View supports it as it implements the IPageableItemContainer. However support is likely to be added to other List controls as well.

LINQ:
LINQ (Language Integrated Query) adds native data querying capability to C# and VB.NET 2008 along with the compiler and Intellisense support. LINQ is a component of .NET Framework 3.5. LINQ defines operators that allow users deploy the query in a consistent manner over databases, objects and XML.

Extra Advantages on ASP.NET 3.5:
1) Previous version of visual studio, Visual Studio 2005 supports only ASP.NET 2.0, but the brand new Visual Studio 2008 support backward compatibility, which able to support ASP.NET 2.0 and ASP.NET 3.5 as well.

2) Users can control multiple version of ASP.NET, ASP.NET 2.0, ASP.NET 3.5 on the same computer machine.

3) ASP.NET 3.5 provides better support and configuration for IIS7 hosting.

Visual Studio 2005’s Typed DataSet is pretty cool. It gives you good control of what the relations should be and it pretty much mimics a table in the database. I love it. But one thing I hate about that is when you serialize your Typed DataSet your XML looks not up to the mark of what you want.

It does serves the purpose but it has all sorts of primary key/foreign key references that are serialized into the XML that at times we don’t want. Rather what we want is a nested XML structure that meaningfully makes sense if you wear that XML glass.

Adding an XSD file to your project won’t help right away as VSNET 2005 doesn’t directly generate dataset (.Designer.cs file) out of it. But, to our rescue, there is a work around to get VSNET 2005 generate typed-dataset from an XSD file. Here is what you should do,

• Select the XSD file you want VSNET 2005 to generate typed-dataset from
• Go into the XSD file’s properties
• Set the "Build Action" to "Content"
• Set the "Custom Tool" to point to "MSDataSetGenerator"

And that’s it. The next time you save the XSD file you should be able to see the dataset file, .Designer.cs (or .vb) file, for your XSD.

Попросили меня в пятницу посидеть на работе трое суток, разумеется за доп.плату. Я согласился

И так первая ночь (с пятницы на суботу):

Скачал пару фильмов, посмотрел. Хотел было лечь поспать, но как на зло

не смог заснуть на новом месте, и мухи доставали.

Суббота: день + ночь с субботы на воскресенье

Весь день следил за плиточниками (просто делать больше ничего не хотелось), ближе к вечеру решил поиздеваться над видовым серваком. Там у нас стоит user gate 2.8 на проксе.. как-то мне он не сильно нравиться, подшлючивает его. Хотелось бы версию по новей, но серийник только на 2.8. Может у кого-нибудь есть на 4.0, поделитесь плиз, а то я гуглил гуглил, так ничего и не поймал.

Так вот, решил поставить Traffic Inspector PE 1.1.5. Скачал, ставить – а фиг. Требует Net Framework 2.0. Скачал и его, для установки потребовал Windows Installer 3.0.

Скачал и енту дрянь – а меня всё равно посылаю вон. Надо Service Pack 1 и не ниже.. а винда у меня голая.

ну плюнул я на это дело и скачал первый пак, который в итоге у меня не установился по не понятным причинам, что-то типа не соответсвия ключей.

Было решено поискать более раннюю версию. После пары часов серфа, скачал верси с 1.0.9 до 1.1.4.

Поробовал с самой ранней, не установилась ”из-за ошибки” которую я не смог выяснить, то же произошло и с версиями до 1.1.4.

А вот 1.1.4 установилась, запустилась, но потребовала ключик лицензионный и сказал что работать будут пока что только 3 фильтра и не больше.

В итоге, по самое утро (часов в 5) мне пришла в голову идея – скачать Windows Server 2003 R2 SP2, что я и сделал, а так же нашёл кряки для Traffic Inspector 1.1.4.

Дело осталось за малым, скачать – 1,5 часа, записать на диск – 20 мин. Установить новую винду и настроить всё как было, опять все пользователи, права, поднять все нужные сервисы – 3-4 часа.

В 6 утра не выдержал и лёг спать, предварительно поставив помещение с сервером на охрану.

И вот теперь по причине отсутсвия связи телефонной, не могу снять это помещение с охраны, если просто открою.. приедет маски-шоу и за ложный вызов возьмут много денег. А я ведь остался подзарботать, а не растратиться.

Вот и сижу в воскресный (для кого-то праздничный день (День независимости Украины)) незнаю чем себя занять, чтобы такое сотворить, на баше новых цитат нет, почитать нечего., посмотреть тоже. Может что подскажите на такие случаи, чем можно занять себя на рабочем месте?

Aşağıdaki kod örneğini kullanarak belirlediğiniz harf veya rakam aralıklarında rastgele şifre oluşturabilirsiniz.

public string GenerateNewPassword(int size)
{
char[] cr = "0123456789abcdefghijklmnopqrstuvwxyz".ToCharArray();
string result = string.Empty;
Random r = new Random();
for (int i = 0; i < size; i++)
{
result += cr[r.Next(0, cr.Length-1)].ToString();
}
return result;
}

Now final version of Visual Studio 2008 (including Express Edition) and .NET Framework 3.5 are released and you can get them from Microsofot website.

平时工作还是在用VS2005和.NET 2.0，新的东东有空还是要好好试试的。

The good news is VS2008 runs side-by-side with VS2005, so it is totally fine to have both on the same box.

More RAM memory or a new video card might be nice             

What do you really need to make vista run

To make Vista’s new bells and whistles work properly requires more powerful hardware for your computer.

  Microsoft’s previous versions of Windows limited the user’s ability to adjust OS (operating system) performance in any useful way, Windows Vista takes care of this by analyzing the components on your computer and automatically turning off features your computer doesn’t have the ability to handle efficiently.  Don’t let this improved flexibility in control fool you, it’s still a good idea to know what sort of performance you can expect before you buy and install Vista, so Microsoft has published two types of system requirements for Vista: Windows Vista Capable and Windows Vista Premium Ready.  Vista ready is a lower tier of requirements necessary for Vista to operate efficiently, just not the advanced features like Aero Interface’s 3D graphics which require a more robust system.  Windows Vista Premium Ready is the higher set of computer specifications necessary to run Vista’s premium features.

  Because of this you won’t need the newest video card or the fastest processor just to run Vista, but you may not be able to use all its new features unless your computer meets the rather hefty Vista Premium Ready system requirements.  In this hub well cover Vista’s two tiers of system requirements and demonstrate how to test if your computer can run Vista efficiently. 

  When a program lists both system requirements and recommendations, it’s a safe bet that you need to meet the recommended specifications if you want to use the software effectively.  If a computer meets the system requirements of Vista Premium Ready – no matter which edition you may choose – Vista should run correctly, and you should get to experience the full capabilities of the Aero interface (such as real-time thumbnail previews in the Taskbar).  Microsoft defines a Vista Premium Ready computer as having at least a 1GHz processor (32- or 64-bit); 1GB of RAM memory; a DirectX 9-capable graphics card with 128MB of onboard memory and a WDDM (Windows Display Driver Model) driver, as well as support for Pixel Shader 2.0 and 32 bits per pixel color depth; a 40GB hard drive with 15GB of free space; a DVD-ROM drive; and Internet access.  If a computer doesn’t have at least 512MB of memory and 15GB of space, Vista won’t even install.  In addition, Vista comes on a DVD instead of a traditional CD, so if you don’t have a DVD-ROM drive you will have to seek alternate routes, fortunately, you can order CD’s from Microsoft online at www.microsoft.com/windows/products/windows/vista/buyorupgrade/ordercd.mspx.  We recommend that if you invest in the Vista Business, Vista Home Premium, or Vista Ultimate editions you should consider Vista Premium Ready system requirements as the base capability your system will need to adequately run Vista.

  The best part of the Vista experience is the Aero interface, but a computer that only just reaches the Vista Capable tier will only display the standard interface, which may look similar to the Aero interface but without any of the neat effects.  If your computer meets the Vista Capable requirements it’s a good candidate for either Vista Home Basic edition, which doesn’t include the Aero interface or other hardware-intensive features, or to be upgraded for use with more powerful versions of Vista.  If your unsure whether you’re PC can handle Vista or which version suits your current hardware, we suggest you download and install the Windows Vista Upgrade Advisor from www.microsoft.com/windows/products/windowsvista/buyorupgrade/upgradeadvisor.mspx and then click the Download Windows Vista Upgrade Advisor link.

  Things to do before you decide to migrate over to Vista

  The Windows Vista Upgrade Advisor scans a PC to see if it can handle Vista’s system requirements, determine which Vista edition is best for your computer, and provide hardware upgrade recommendations.  Note the Upgrade Advisor doesn’t work on computers that run versions of Windows older than Windows XP Service Pack 2.  When you head over to the link above select your connection type using the Download Size drop-down menu and then click the Download button and select Run.  Once the tool finishes downloading, the Windows Vista Upgrade wizard will appear to lead you through the installation process, if Advisor doesn’t launch following installation, click the Start button, select All Programs, and click Windows Vista Upgrade Advisor, then click the Start Scan button (which should be your only option).  It took about three minutes for the Advisor to load when we tried it, once it’s finished, click the See Details button to see how your system stacked up.

  The very top of the screen will indicate if your computer can load and run Vista and which version the Advisor recommends for your system to run Vista efficiently.  If the Advisor reports your system as being inadequate, examine the results under System Requirements to determine what components are holding you back from Vista heaven, the Advisor will point out specific problems with your systems hardware in the Action Required column.  Once finished with the Upgrade Advisor we suggest you delete the program from your computer, by clicking the Start button, selecting Control Panel, and choose Add Or Remove Programs.  Then select the Windows Vista Upgrade Advisor from the list and click the remove button to remove from your computer.

   Well that’s it for another hub on Microsoft’s newest baby Vista for now.  Join us next hub as we will discuss a few ways to tweak the OS to help it run more efficiently.  Until next time, happy hubbing!  

                       Vista Unrolls the Features for All to See

 Microsoft renamed all your old favourites and added a few more that will knock your socks off 

  Microsoft’s new operating system Vista comes with a host of new bells and whistles, amazing features and of course a whole new jargon to learn, fortunately, the new language is pretty easy to remember.

  The first thing we noticed was Microsoft had dropped their obsession with the word “My” in favours of a whole new terminology to sink you’re teeth into.  In stead of My Computer there is only Computer, how novel, maybe one day they’ll go with simplicity.  Many of the featured names have been dropped too, Outlook Express has now become Windows Mail as you will notice when you first try to e-mail.  The majority of the new language refers to new features never seen before, but the best way to learn the new lingo is to use these hubs to learn about the new features – the terminology you’ll naturally pick up the more you use it in every day business.

  There have been specialized versions of Windows in the past – for example Windows XP Home and XP Professional – Vista is the full load of the segmentation of Microsoft’s product line.  There are four versions of Vista available on the market; Home Basic, (for users who want to upgrade but don’t have PC’s that run Home Premium), Home Premium (for the average user), Business (for the most businesses), and Ultimate (for the hobbyist and power user).  Microsoft has also included an Enterprise version for large businesses that require special functions in their daily business operations.

  In this hub, we focus very often on Home Premium, a version very popular with average users and offering the vast majority of Vista’s most useful features.  We also discuss the other versions in order to cover new features Home Premium doesn’t include in its package.

  Microsoft has included so many new and improved features that it will be easier to consider the major improvements in categories and we begin listing them below.

  Security and safety for the data contained on Microsoft computers has been of great concern since Microsoft first brought out their first operating system.  With Vista Microsoft has increased the security features in order to try to rid themselves of the reputation for weak security on their systems.  Windows firewall makes a return appearance from Windows XP, while spyware fighter Windows Defender is now standard in Vista.  Also a standard is Windows Explorer 7, which also offers beefed up security and a host of new features and capabilities.  Vista’s User Account Control prevents changes to your PC by prompting you for permission before Windows allows any substantial changes to the system.  For the curious little ones, Parental Controls allow you to set the system up to keep prying little eyes away from the dark corners of your computer system and the Internet.

  Vista is designed to allow the user to get more out of a work day with features designed with this specifically in mind.  Windows Mail and Windows Calendar offer substantial upgrades from previous functionality of the programs.  You can share you’re event schedule with online friends, while Mail has improved security and a better interface than its predecessor, Outlook Express.  Windows Meeting Space allows you to collaborate with others on your network from the comfort of home or office. 

  Vista comes with a new interface, Windows Aero, which is the most obvious difference when you first turn on a computer system using Vista.  Windows Aero comes with many bells and whistles to entrance you, one of which is they are now partially transparent so you can see what’s underneath the top window.  The new Sidebar contains useful “gadgets” that allow you to put useful little tools within easy reach such as a view of upcoming events on your schedule, breaking news stories, or put notes on your screen so you never forget and new ones are being created all the time that you can downloaded from the Internet. 

  Microsoft has announced they will be taking computer gaming seriously with improved gaming game play elements and improved functionality.  Games Explorer is a new way to categorize and browse installed games so you don’t have to memorize in which file location you have put a certain game or under what name.  The new DirectX 10 offers better graphics and audio output to improve the immersive ability of games.

  Yes Vista does require more hardware to run quickly and efficiently but the operating system includes a host of new tools for improved performance and system stability.  You can even use a memory stick to improve performance through Windows Ready Boost.  Microsoft’s new Self-Healing System and Shadow Copy features help keep Windows Vista running cleanly and efficiently if you forget to tweak your system.  Vista even comes with Backup and Restore Center, a feature much improved from earlier such capabilities.

  Microsoft has also built in some capabilities that are harder to see in action, unless you have x-ray vision.  SuperFetch speeds the way Vista uses your PC’s memory in order to increase the systems performance.  Vista even automatically defragments your hard drives, before decreased performance reminds you of your neglect.  ReadyDrive offers support for hybrid hard disks that might not normally perform well otherwise, which should offer improved reliability and performance.  Vista new features keep an eye on your systems performance behind the scenes in an effort to head off trouble before you see issues and take some workload from your plate.

  Vista comes with features for mobile computing like Windows SideShow, which allows compatible hardware to show information in a secondary screen on the device.  Notebooks have received added attention this time, receiving better support with a new interface that allows most commonly changed notebook settings (volume, brightness, battery status, wireless networking, etc.) to be constantly monitored and changed in one location.  Microsoft has included better support for tablet PC’s with Vista so users can enjoy the full benefits of Vista’s added features.

   Well that’s it for this hub.  Join me tomorrow for more information on Microsoft’s new operating system Vista.  Happy hubbing!

An operating system for everyone 

Build Vista and They Will Come

 After nine years and a highway of hype Vista has finally arrived on the newest Microsoft computers, was it worth the wait? 

  Longhorn, now called Vista, has finally arrived! 

  The nine years of build up to the final release date resulted in more of a yawn from consumers compared to previous Windows operating system releases – were thinking in particular about the circus-like environment surrounding the release of Windows 95.  Having finally made an appearance we can expect Vista to have a major impact on the computing industry as a whole.  So, how can we expect it to affect our computing lives?

  Even if Vista didn’t offer any new capabilities and features to the user, it would still dominate a majority of the computing time of daily users of computers.  The biggest software company on the planet cannot drop a new version of its flagship product onto the global market without creating a few waves in the industry.  And don’t be fooled, the percentage of Microsoft’s market share in desktop operating systems – consistently over 90% during the last decade – means any changes made to Windows reverberates right through the computing industry.

  The biggest effect a new operating system for Windows has is in the sales of hardware necessary to upgrade to Vista.  If you want to upgrade you may find you will need more memory, more processing power, more power in all aspects of computer architecture to get your upgrade to operate efficiently and make the upgrade worthwhile.  In fact, Microsoft recommends that your computer have at least a 1 GHz processor, 1GB of RAM, a 40GB hard drive with at least 15GB of free space to load Vista, a graphics card that supports DirectX 9, Pixel Shader 2.0, WDDM, and includes 128MB of graphics memory, a DVD-ROM drive, and Internet access.  So, obviously, many people looking to upgrade to Vista will have to upgrade their hardware before partaking in the benefits of Vista.  In addition, if you wish to use new features like SideShow, Vista’s technology that lets the user display data your system pushes to secondary screens, you’ll be shelling out a few more shekels at the counter for additional hardware upgrades.

  Let’s put aside the shekels Microsoft’s new operating system is going to make and is currently making for hardware vendors around the global marketplace for a second.  Vista does include a slew of new and improved capabilities and features that will make operating a Windows PC a lot more fun, it’s always fun to learn new stuff, and easier once they learn the ins-and-outs of Vista.  Vista improvements in security were needed with this new Microsoft operating system as they have been a major issue with previous Microsoft operating systems in the past and should contribute to increased productivity for all users and fewer global security crises due to inappropriate behaviour of individuals.  Vista also represents another major move toward having your PC at the center of home entertainment, by controlling audio systems, TV, and other multimedia components around your home.

  In short, Vista provides many new features and capabilities for you to grab onto and enjoy.  While no one feature will knock your socks off, you should find a few tidbits to keep make the nine year wait (four years from the expected release date) for Vista worthwhile, and hopefully justify your upgrade to Vista and probably some new hardware as well.

Vista: The Last Chapter?

  Upon the release of Vista speculation immediately started about the next version of Microsoft’s operating systems – or even if Microsoft would do one.  A lot of speculation has centered on the idea that Vista is Microsoft’s last version of Windows to be released.

  Despair not Windows lovers, Microsoft is indeed in development of a new version of Windows for you to dream about, currently code-named “Vienna” (and we mean currently) only god knows when to expect Microsoft’s next attempt at operating system perfection.  Microsoft has sealed lips about the eventual release of “Vienna, even going to the extent of releasing a rather terse press release in February 2007 trying to quash rampant speculation about the new operating system they have in development.

  We searched Microsoft.com for references to “Vienna”, resulting in a rather sharp joke as our search resulted in the appearance of several excellent pictures of Vienna in Austria.

  Microsoft isn’t ready to go on the record yet, it would be hard to say would features would be making it into a new version of Windows anyway – just check out the list of planned features that didn’t get included in Vista: WinFS, PC Synchronization, and the scripting shell.  Although were sure these features will all be included in the next Windows version, were just as sure there will be many currently planned features that won’t make it off the drawing board and into “Vienna” because it takes tremendous effort and time to make these features work.

  The only thing we are sure of concerning the arrival of “Vienna” onto the store shelves is that it will be late as usual. 

   Well that’s it for this hub.  Join us for the next hub on Vista as we will talk about the new features and capabilities of Microsoft’s new operating system.Warren Hayashi (a.k.a. Mark Twain)   

The newest tool around the office 

                             Move On Up to Vista Business Edition

                            If your ready to say Bon Voyage to Windows XP Pro & Hello to Vista 

  Welcome traveler to our continuing hubs on everything Vista; today well tell you how to make the jump from Windows XP Pro to Vista.  If you’re ready, here we go.

  If a few years ago like millions of loyal Microsoft fans you made the jump from Windows 2000 to Windows XP Pro.  And now have decided to make the move from Windows XP Pro to the scintillating world of Vista Business Edition, Microsoft’s small business version of its latest operating system.  You could be having a few nervous twitches at the though, considering the trials and tribulations of upgrading to Windows XP Pro.

  Relax, the process isn’t the slow, excruciating, pain you remember from the first time you trusted Microsoft and made the move to WinXP.  It’s possible, there could be a stumble of two, but most reports by users indicate the upgrade was painless compared to the move to WinXP, maybe Microsoft might be learning, yeah right!

  First things first, make sure you download and run Microsoft’s Vista Upgrade Advisor on every WinXP computer on which you plan to install Vista Business Edition.  Remember, this utility will tell you if the PC is ready to be upgraded to Vista and indicate if there are any compatibility problems with your hardware and Vista.  Go to the www.microsoft.com Web site and type Vista upgrade advisor in the Live Search box, click the first result and follow the instructions for downloading the program.

  At this time you should backup all vital files, folders, and settings in WinXP before starting the upgrade.  This can be accomplished using either a third-party backup program or WinXP’s Backup Utility (click Start and choose All Programs, Accessories, System Tools, and Backup).  Whatever path you decide to take, just plan for all contingencies, including important files, browser favourites, email settings and messages, documents and any other data impossible or difficult to find or replace.

  Now, to begin the upgrade installation to Vista Business Edition, boot into WinXP and insert your Vista Business CD or DVD in your optical drive.  If Autorun is enabled, Vista installation utility will automatically start, but if Autorun is disabled, you can manually start the utility by clicking your optical drive in Windows Explorer and clicking Setup.exe.

  If the version of Vista Business you’re using is a downloaded one, click Install from your digital locker.  The program will download three files, including an executable (EXE) file, which will mean a File Download Security Warning will appear.  Click Save, and be sure to download and save all the files in the same directory, after the files have finished downloading, open the directory and double-click the executable file to launch Windows Vista Setup.

  The first screen that appears will have several options for you to choose from.  And although you should have already backed up your important data and settings in WinXP, you will have the option of transferring files and settings from another computer using a transfer cable, an optical disc, or removable media.  It should be noticed at this time that after installing and configuring Vista Business on this PC, this can be a useful step that will save time when installing the OS on other computers.  To launch Windows Easy Transfer, click Transfer Files and Settings and follow the instructions provided by the program.

  Next, click Install Now and Vista will offer you the opportunity to go online to download the latest updates for your new operating system.  If you are connected via the Internet, lick the first option, Go Online To Get The Latest Updates For Installation, to ensure that Vista has the latest drivers to aid the installation process.

  After upgrading to the latest drivers (or if you decided not to obtain updates), the following screen will ask you to enter your product key for activation.  It’s not necessary to enter the key at this time, but we suggest you do to avoid Murphy causing problems later.  You should also click on the Automatically Activate Windows When I’m Online to avoid being pestered about activation after your finished installing Vista Business Edition.

  When the next screen pops up it will feature the licensing terms for Vista Business, and while you can theoretically click to accept the terms and move on, Vista consumers should read word-for-word the terms of the agreement to understand Microsoft’s guidelines for using the OS, such as storing Vista on network servers, using it over networks, and others.  Read the terms carefully and then click I Accept The License Terms and click Next.

  Next, you’ll be given the choice to either upgrade your existing OS or install a clean copy of Windows.  In this instance, we’re upgrading to Windows, so select Upgrade.  Vista then checks for compatibility problems and informs you of any possible questions that exist with applications and devices.  If you’re wondering about the particulars of any issues, select Click Here For More Information or just click Next to head to the installation.

  It will take a few minutes while Vista Business automatically processes the rest of the upgrade by copying Windows files from the disc, gathering the files, expanding them, installing features and updates, and finishing the process.  You will see a single Upgrade Windows screen displayed and Vista will occasionally reboot the computer while it’s performing this magic.

  You will need to stand by the computer while this is going on as Windows will present you with a screen that wants to know if you want to Use Recommended Settings, Install Important Updates Only, or Ask Me Later.  The intelligent selection is Use Recommended Settings to ensure Vista Business is secure from the start, but if you decide on one of the other two options, make sure you review the security settings on the computer when the installation is finished.  After this, you’ll be asked to look-over your time and date settings, make the selections you want on this screen and click Next.

  The final step is for the program to launch the Vista Business Desktop.  If Vista looked and didn’t find any drivers for any of your hardware devices during the installation process, it will probably look for and find new drivers at this point.  If a screen pops up asking if you want to Locate And Install Driver Software, Ask Me Again Later, or Don’t Show This Message Again For This Device it’s the program trying to find the drivers.

  We suggest you click the first option at this time, but this is of course up to you.  The will then be introduced for the first time to Vista’s User Account Control feature, which needs administrator permission before it can perform certain actions.  A User Account Control dialog box will appear next, that asks you to click Continue to perform the action or Cancel to prevent the action from continuing, click Continue.  At this point Vista will ask you to install the disc that came with the hardware device, if you have the disc, insert it, click Next, and carry out the instructions provided for installing the necessary drivers.

  If you don’t have the disc, you can click I Don’t Have The Disc to see other options for this contingency.  One option for this will be Browse Your Compute For Driver Software, which can be useful if you earlier downloaded the driver from the manufacturers Web site to your hard drive (the other option is Check For A Solution, which probably won’t produce any real results, it didn’t when we tried it).

  It is possible that some hardware devices don’t work properly with Vista’s default drivers, just visit the device manufacturer’s Web site and download the latest Vista –ready drivers for the hardware.  That’s it, once the devices are running smoothly; it’s time to enjoy the experience that is Vista.

  Well that’s it for another hub on everything Vista, time for a richly deserved breath and coffee.  We hope this hub helps you with any problems you might experience in the transition from Windows XP Pro to Vista.  Until next time traveler, happy hubbing!
