Hi guys, i wrote code which doesn''t work correctly.. the dialog appears but you can''t close it... i took most of the code from Charles Petzold''s book, but nothing he described about this topic does really work.. here''s the code - can you see what''s wrong? #include #include "resource.h" LRESULT CALLBACK WndProc(HWND,UINT,WPARAM,LPARAM); BOOL CALLBACK DlgProc(HWND hwnd,UINT iMsg,WPARAM wParam,LPARAM lParam); int WINAPI WinMain(HINSTANCE hInstance,HINSTANCE,LPSTR,int iCmdShow) { static char szAppName[] = "pCalc"; HWND hwnd; MSG msg; WNDCLASSEX wndclass; // set up window settings wndclass.cbSize = sizeof(wndclass); wndclass.style = CS_HREDRAW/CS_VREDRAW; wndclass.lpfnWndProc = WndProc; wndclass.cbClsExtra = 0; wndclass.cbWndExtra = DLGWINDOWEXTRA; wndclass.hInstance = hInstance; wndclass.hIcon = LoadIcon(NULL,IDI_APPLICATION); wndclass.hCursor = LoadCursor(NULL,IDC_ARROW); wndclass.hbrBackground = (HBRUSH)(COLOR_WINDOW+1); wndclass.lpszMenuName = NULL; wndclass.lpszClassName = szAppName; wndclass.hIconSm = LoadIcon(NULL,IDI_APPLICATION); // register it RegisterClassEx(&wndclass); // create and show dialog hwnd = CreateDialog(hInstance,MAKEINTRESOURCE(pCalc),0,(DLGPROC)DlgProc); while(GetMessage(&msg,NULL,0,0)) { TranslateMessage(&msg); DispatchMessage(&msg); } return msg.wParam; } BOOL CALLBACK DlgProc(HWND hwnd,UINT iMsg,WPARAM wParam,LPARAM lParam) { switch(iMsg) { case WM_DESTROY: PostQuitMessage(0); return FALSE; } return FALSE; } LRESULT CALLBACK WndProc(HWND hwnd,UINT iMsg,WPARAM wParam,LPARAM lParam) { switch(iMsg) { case WM_DESTROY: PostQuitMessage(0); return 0; } return DefWindowProc(hwnd,iMsg,wParam,lParam); } Please help me... thanks...!

In your dialogproc.

Shouldn''t u return true when u receive the WM_DESTROY

If u return false, then you are saying you did not process the message.

Maybe you should bracket the case statement too.
