Thanks in advance to anyone who can help me. The code below is the problem. Basically what i have done is i have a standard WinMain function declared correctly, it works, below is where i have tried to move the windows creation code to a function called WinMainBase which lies inside a class. I have passed all appropriate variables to the function and all possible handles are available to it. The errors that the compiler gives are : error C2440: ''initializing'' : cannot convert from '''' to ''long (__stdcall *)(struct HWND__ *,unsigned int,unsigned int,long)'' None of the functions with this name in scope match the target type error C2440: ''initializing'' : cannot convert from ''struct HINSTANCE__ *'' to ''int'' This conversion requires a reinterpret_cast, a C-style cast or function-style cast error C2440: ''initializing'' : cannot convert from ''char [11]'' to ''struct HBRUSH__ *'' Types pointed to are unrelated; conversion requires reinterpret_cast, C-style cast or function-style cast Error executing cl.exe. Creating browse info file... RobustBasicWindow.exe - 3 error(s), 0 warning(s)
WinMainBase( HINSTANCE hInst, HINSTANCE hPrevInst, LPSTR, INT, HWND hWnd )
	l_hWnd = hWnd;

    WNDCLASS wndClass = {	0,
							"D3D Window" };

    RegisterClass( &wndClass );

    l_hWnd = CreateWindow( "D3D Tutorial", "D3D Tutorial 01: CreateDevice", 
                              WS_OVERLAPPEDWINDOW, 100, 100, 300, 300,
                              GetDesktopWindow(), NULL, wndClass.hInstance, NULL );
	if (l_hWnd
		== NULL)
		MessageBox(l_hWnd, "Function CreateWindow() Failed!", "Function Failure!", MB_OK);
I have also tried using the class WNDCLASSEX and RegisterEx as well and the same problem occurs. The only way i can get the code to compile is if i remove teh "msgProc" parameter. BTW the MsgProc exists and is also a function inside the same class. Hope someone can help regards, ace

A window''s msgproc cannot be inside a class unless they are static .
But you could make it static and then store a pointer to your class
in your window''s user data.

Sorry for my bad English.
I hope I helped.
