I am working on my first game engine (just started). I am having problems w/ registering my windows class. I have tryed so many thing i cant understand why. I am running on XP and can only think that could be the problem. I will post the code below and if you could tell me where my error lies that would be great. Thanx for the help! ========================== code starts below ========================== WNDCLASSEX windowC; windowC.style = CS_HREDRAW |CS_VREDRAW | CS_OWNDC; windowC.lpfnWndProc = (WNDPROC)::WndProc; windowC.cbClsExtra = 0; windowC.cbWndExtra = 0; windowC.hInstance = hInstance; windowC.hIcon = LoadIcon(NULL, IDI_APPLICATION); windowC.hCursor = LoadCursor(NULL, IDC_ARROW); windowC.hbrBackground = (HBRUSH)(COLOR_WINDOW+3); windowC.lpszMenuName = NULL; windowC.lpszClassName = WIN_NAME; windowC.cbSize = sizeof(WNDCLASSEX); windowC.hIconSm = LoadIcon(NULL, IDI_WINLOGO); if(!RegisterClassEx(&windowC)) { MessageBox(NULL,"Failed to Register Class!","ERROR", MB_OK | MB_ICONEXCLAMATION); return FALSE; } if(!(hWnd = CreateWindowEx( NULL, WIN_NAME, title, WS_OVERLAPPEDWINDOW | WS_VISIBLE, 0, 0, width, height, NULL, NULL, hInstance, NULL))) { appKillGLWindow(); MessageBox(NULL,"Failed Window Creation","ERROR",MB_OK | MB_ICONEXCLAMATION); return FALSE; } ========================= code ends ========================= Thanx again. : )

ok i take the :: between the WndProc and (WNDPROC) and i get an error: C:\Program Files\Microsoft Visual Studio\MyProjects\MercuryTree\Ren_0001\CWindowApp.cpp(34) : error C2440: ''type cast'' : 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

HELP

Help Please if you can! Thanx

I would say it is probably a problem with your hInstance.

What value are you giving it?

You either have to pass it the value given to your program when it is started (the WinMain hInstance value), or you have to get a handle.
