Hello. I have recently started with windows programming. I have now done a simple program that makes a window from a resource. The problem is, i cannot close it. Heres the code: /* Trim windows header */ #define WIN32_LEAN_AND_MEAN /* Includes */ #include <windows.h> #include "resource.h" /* Global variables */ HWND hWnd; // Window handle char className[] = "Liquid Silver"; // Class name /* Function prototypes */ int PASCAL WinMain(HINSTANCE, HINSTANCE, LPSTR, int); long FAR PASCAL WindowProc(HWND, UINT, WPARAM, LPARAM); /* Start of application (WinMain) */ int PASCAL WinMain(HINSTANCE hInst, HINSTANCE hPrev, LPSTR szCmdLine, int nCmdShow) { WNDCLASS wc; MSG Msg; /* Register the window class */ wc.style = CS_HREDRAW | CS_VREDRAW; wc.lpfnWndProc = WindowProc; wc.cbClsExtra = 0; wc.cbWndExtra = DLGWINDOWEXTRA; wc.hInstance = hInst; wc.hIcon = LoadIcon(hInst, IDI_APPLICATION); wc.hCursor = LoadCursor(NULL, IDC_ARROW); wc.hbrBackground = (HBRUSH)(COLOR_BTNFACE + 1); wc.lpszMenuName = NULL; wc.lpszClassName = className; RegisterClass(&wc); /* Create window from file */ hWnd = CreateDialog(hInst, MAKEINTRESOURCE(IDD_WINDOW), 0, NULL); UpdateWindow(hWnd); ShowWindow(hWnd, nCmdShow); /* Message loop */ while(GetMessage(&Msg, NULL, 0, 0)) { TranslateMessage(&Msg); DispatchMessage(&Msg); } /* Clean */ UnregisterClass(className, hInst); return 0; } LRESULT CALLBACK WindowProc(HWND hWnd, UINT msg, WPARAM wParam, LPARAM lParam) { switch(msg) { case WM_COMMAND: switch(LOWORD(wParam)) { } break; case WM_DESTROY: PostQuitMessage(0); break; default: return DefWindowProc(hWnd, msg, wParam, lParam); } return 0; }

Sorry pag, the first thing didn''t compile and i don''t understand what you mean with the other statement.

But thanks for trying to help.

Ohh, i forgot to call it. Ooops. I will try again.

I cannot figure out how the call to WindowProc() will look like.
I tried this:

hWnd = CreateDialog(hInst, MAKEINTRESOURCE(IDD_WINDOW), 0, WindowProc(hWnd, msg, msg.wParam, msg.lParam));

And I got the following error:
error C2664: ''WindowProc'' : cannot convert parameter 2 from ''struct tagMSG *'' to ''unsigned int''
This conversion requires a reinterpret_cast, a C-style cast or function-style cast

Still having trouble. I tried your pice of code and got a new error:

error C2664: ''CreateDialogParamA'' : cannot convert parameter 4 from ''long (struct HWND__ *,unsigned int,unsigned int,long)'' to ''int (__stdcall *)(struct HWND__ *,unsigned int,unsigned int,long)''
None of the functions with this name in scope match the target type

If you''re using CreateDialog, then your window proc should be declared like this:

BOOL CALLBACK DialogProc(HWND, UINT, WPARAM, LPARAM);

and should be passed as a function pointer into CreateDialog. Also, if you''re using dialogs, you don''t need to register a WNDCLASS.

Also, a dialog procedure shouldn''t call DefWindowProc. It should return TRUE if it processes the message, and FALSE if not.
