What is WPF?

WPF stands for Windows Presentation Foundation and it is essentially a new API for creating a graphical user interfaces for the Windows platform. It provides a consistent programming model for building applications and provides a clear separation between the user interface and the business logic. WPF employs the use of 2D and 3D drawing, fixed and adaptive documents, advanced typography, vector graphics,raster graphics, animation, data binding, audio and video thanks to the presence of DirectX in one of the lower levels of its architecture. WPF comes pre-installed on Windows Vista and i based on .NET 3.0. Although like its predecessor, WinForms, it too incorporates the use of buttons, combo-boxes, list-boxes etc, instead of using a designer generated code file or a resource file as the source of a UI definition, it makes use of XAML (Extensible Application Markup Language) which is a unique way of including code in a mark up.

PS: I apologize if this answer seems inadequate for i answered only because of the statement : Even if you can't offer a complete answer, help us get things started

If you are interested in WPF, also check out the Silverlight which is a cross-browser, cross platform plugin, that provides rich web based content to your browser. Silverlight is basically the web implementation of WPF.

Can a derived class call the static constructor of a base class in .Net?

No. not directly.

The static constructor is called by .net framework, not by your code.

I always treat static constructor is the class initializer (not the instance one). The initialization routine is only called when the class definition being loaded.

When the derived class is loaded, since this class derived from the base, it makes to go up the chain (of the hierarchy) to call those static constuctors.

So, when a derived class is loaded, the static constructors of the hierarchy is called up. (any one of them had been loaded, the calling sequence stops).

You cannot call those static constructor directly, nor you can skip "not to execute" them.

Fibonacci series program in vb.net?

This is not a homework board. I will give you a rough algorithm in C#

int firstnum= 1;
int finalnum = 1;

int nextNumber;

System.Console.Write(finalnum + " ");

while (finalnum < 50)
{
System.Console.Write(finalnum + " ");

nextNumber = finalnum + firstnum;

firstnum= finalnum ;
finalnum = nextNumber;
}

Why do you need to create an object reference variable to call methods cant you directly use the objects that is created?

Creating an object and invoking a method of that object are 2 distinct steps. From good programming practice, it is better off to have 2 separate statements at least to do this.

For example:

(new object()).ToString(); // creates an instance and invoke ToString()

vs.

object objRefence = new object();

objRefence.ToString();

The variable objReference is needed to invoke the method ToString(), because the object refereced of the one being created from the new operator needed to be cached somewhere.

There is no major differences between the 2 above. However, if there is another method to be invoked, the second way (use variable reference) is the only way, the first one cannot. (You can replace ToString() with GetHashCode(), and prints it on the console twice, the first one may produce 2 different values, while the second one will be the same value. Think of GetHashCode() returns the object id in a way)

Use of Interlocked class in vb. net?

The Interlocked methods protect against errors that can occur when the scheduler switches contexts while a thread is updating a variable that can be accessed by other threads. The members of this class do not throw exceptions.

[Note: The System.Threading.Interlocked.Increment(System.Int32@) method and its counterpart, System.Threading.Interlocked.Decrement(System.Int32@), increment or decrement a variable and store the resulting value, as an atomic operation.

The System.Threading.Interlocked.Exchange(System.Int32@,System.Int32) method atomically exchanges the values of the specified variables. The System.Threading.Interlocked.CompareExchange(System.Int32@,System.Int32,System.Int32) method provides an atomic operation that compares two values and stores a third value in one of the variables, based on the outcome of the comparison.

Do you need dot net if you do not program?
