[/CODE]

now can some one tell me why this progrm is gettn stucked at CreateWindow() as it cannot get a handle to the window....so according to my prog...its giving a messagebox "Failed to create window"...

2 Suggestions:

1st, instead of just popping up a Create Failed message box, call getlasterror() and find out exactly why the window is failing to create.

2nd, post the code for you WndProc, CreateWindow processes several messages before it return, namely the WM_CREATE, which if not handled properly could cause createwindow to return an error.
