Bjam build system. If bjam is not already installed run bootstrap.bat located in the boost folder to install it.

Static Multithreaded:

bjam toolset=msvc-9.0 variant=debug threading=multi link=static runtime-link=static define=_BIND_TO_CURRENT_VCLIBS_VERSION –without-python –without-mpi

Dynamic Multithreaded:

bjam toolset=msvc-9.0 variant=debug threading=multi link=dynamic runtime-link=dynamic define=_BIND_TO_CURRENT_VCLIBS_VERSION –without-python –without-mpi

Note: The builds exclude python and mpi support

public class MyClass

{

         [Obsolete(“My Reason”,  false)]

         public void OldMethod()

        {

        }

       public void NewMethod()

      {

      }

}

Now your “OldMethod” is been marked as obsolete and the compiler would raise as warning when you try to use it. In case you want the compiler to report an error instead of a warning you need to change the 2nd parameter of the obsolete attribute to true.

The “Obsolete” attribute can be used on class.

[Obsolete(“My Reason 2”, false)]

public class MyObsoleteClass

{

    public void foo()

    {

    }

}

Here is detail of the Obsolete class as mentioned in msdn

[AttributeUsage(
      AttributeTargets.Class |
      AttributeTargets.Struct |
       AttributeTargets.Enum |
      AttributeTargets.Interface |
      AttributeTargets.Delegate |
      AttributeTargets.Method |
      AttributeTargets.Constructor |
      AttributeTargets.Property |
      AttributeTargets.Field |
      AttributeTargets.Event,
      Inherited = false)
   ]
   public class ObsoleteAttribute: Attribute
   {
      public ObsoleteAttribute() {...}
      public ObsoleteAttribute(string message) {...}
      public ObsoleteAttribute(string message, bool error) {...}
      public string Message { get {...} }
      public bool IsError { get {...} }
   }

Happy programming and a very Happy New Year 2010 !

Basically IntelliSense code snippets are in real xml files with a .snippet extension that adhere to the IntelliSense Code Snippet XML schema.

You can use any tool to generate the xml file but please remember to save it with a .snippet extension name.

Step 1, you add your root element as

<CodeSnippets xmlns=”http://schemas.microsoft.com/VisualStudio/2005/CodeSnippet”>

Step 2, you add CodeSnippet element for the snippet you want to create as

<CodeSnippet Format=”1.0.0”>

Step 3, Now you need to add two sections within the CodeSnippet element, one is the Header element and the Snippet element.

Add the header section as

<Header>

        <Title> My CSharp Snippet </Title>

</Header>

Now add the snippet element that defines the snippet itself

<Snippet>

      <Code Language=”CSharp”>

      </Code>

</Snippet>

Please note the Language attribute also accepts the values CSharp, VJSharp, and XML. For more information, see Code Element (IntelliSense Code Snippets).

Now you the add the csharp code for the snippet within the code element. If you want the code to be inserted is

MessageBox.Show(“Hello World”);

then the element within the Code element would be

<![CDATA[MessageBox.Show(“Hello World”)]]>

Now your code snippet is ready. Go to Tools –> Manage Code Snippets –> Import to import your code snippet in Visual Studio.

The entire code -

<CodeSnippets xmlns=”http://schemas.microsoft.com/VisualStudio/2005/CodeSnippet”>

         <CodeSnippet Format=”1.0.0”>

                <Header>

                           <Title> My CSharp Snippet </Title>

                 </Header>

                 <Snippet>

                             <Code Language=”CSharp”>

                                         <![CDATA[MessageBox.Show(“Hello World”)]]>

                              </Code>

                  </Snippet>

         </CodeSnippet>

</CodeSnippets>

Later i would discuss more about code snippets. Happy programming.

“Connecting to Google Talk network has failed due to an expired
authentication certificate. The common cause of this expired
certificate is due to time differences between your computer and the
Google Talk network. Please verify your computer’s clock settings
are correct and then press Retry.”

What happened is… by mistake my system date got changed and then i cannot login to gtalk anymore…. Funny right… I guess yes.

I still couldn’t figure out why should there be any check on system date… System date errors can occur… Does that mean an application should fail…

Happy messaging !

One of the many benefits of using a model-view-controller (MVC) architecture is that it helps to maintain a clean separation of concerns between the models, views and controllers within an application.

Now what exactly is a Model View Controller (MVC) Framework?

MVC is a framework methodology to divide an application’s implementation into three component roles: models, views, and controllers.

• “Models” are responsible for maintaining state (don’t confuse it with session state). In a more generalised terms it can be seen as a part of the application which talks to persistent data and is responsible also to provide the views with whatever data it needs.

• “Views” are the application’s user interface and are responsible for displaying the data. Typically this user interface is created off of the model data.

• “Controllers” are responsible for handling user requests, manipulating the model accordingly, and ultimately deciding which view to render to display user interface.

For a detail on MVC architecture take a look at Wikipedia’s.
Personally i think MVC eases out the process for large and complex web sites to add/remove site’s features with disturbing the whole application, but that is beyond the scope of discussion. Maybe on my next blog.

To start of i would definitely recommend developers to go through the these blogs,

Scott Guthrie’s blog on asp.net mvc

• Part 1

• Part 2

• Part 3

• Part 4

This is official microsoft page on ASP.Net MVC

Enjoy programming!

PS: Some ideas has originally been posted on Scott Guthrie’s blog.

Wish i could be as beautiful as this!
