How can I use Windows APi's In C# Programming.........

Thanx dude,

Thanx a lot.....

Regards

First place the following line amongst your using directives:

   using System.Runtime.InteropServices;

Now place the following method declaration in the class from which you want to call FindWindow:

   [DllImport("user32.dll")]
   static extern IntPtr FindWindow(string lpClassName, string lpWindowName);

Notice that the method has no body because this is supplied by the API function itself within the user32 dll.

Now just call the function as you would if it were a C# method. For example to get the handle of an empty Notepad window:

   IntPtr hWnd = FindWindow("Notepad", "Untitled - Notepad");
