Question

I’v created a window after creating my main one but calling DestroyWindow on its handle closes the entire application, how can I simply get rid of it?

it looks like this:

BOOL InitInstance(HINSTANCE hInstance, int nCmdShow)
{
   HWND hWnd;
   HWND fakehandle;


   hInst = hInstance; // Store instance handle in our global variable

   hWnd = CreateWindow(szWindowClass, szTitle, WS_OVERLAPPEDWINDOW | WS_EX_LAYERED,
      CW_USEDEFAULT, 0, CW_USEDEFAULT, 0, NULL, NULL, hInstance, NULL);

   fakehandle = CreateWindow(szWindowClass, "FAKE WINDOW", WS_OVERLAPPEDWINDOW,
       CW_USEDEFAULT, 0, CW_USEDEFAULT, 0, NULL, NULL, hInstance, NULL);

   if (!hWnd || !fakehandle)
   {
      return FALSE;
   }
//some code
   DestroyWindow(fakehandle);


   ShowWindow(hWnd, nCmdShow);
   UpdateWindow(hWnd);

   return TRUE;
}

how can I destroy this window without destroying my main one? I’m creating a dummy window to check for multisampling in OpenGL.

Thanks

I’ve just found this comment:

If the specified window is a parent or owner window, DestroyWindow automatically destroys the associated child or owned windows when it destroys the parent or owner window. The function first destroys child or owned windows, and then it destroys the parent or owner window.

on the DestroyWindow MSDN page.

Could this have some bearing on your problem? Could you be setting the parent of hWnd where you’ve got //some code?
