Hello!

I am fairly new to Win32, and got an question:

I want an overlapped window when I press button ID_LIGHTS_LIGHTMAP.

Function called within the case when clicked on menu button for creation of Window:

+ Code Snippet

void LIGHTMAP_OPTIONS(void)
{
	RECT Rect;
	GetWindowRect(MainWindow, &Rect);
	HWND SettingsWin = CreateWindowEx(0, "BlankWindow", "LightMap Options",WS_VISIBLE, 100, 100, 256, 512, MainWindow, NULL, hInstance, NULL);
	SetWindowLong(SettingsWin, GWL_HINSTANCE, (LONG)LIGHTMAP_WindowProc);
}

Case of the button ID:

+ Code Snippet

case ID_LIGHTS_LIGHTMAP:
				{
					LIGHTMAP_OPTIONS();
				}break;

WindowProc Handler:

+ Code Snippet

//LightMapping Window Proc
LRESULT	CALLBACK LIGHTMAP_WindowProc(HWND hWnd, UINT uMsg, WPARAM wParam, LPARAM lParam)
{
	switch ( uMsg )									
	{
	case WM_COMMAND:
		{
			return 0;
		} break;

	case WM_CLOSE:								
		{
			DestroyWindow(hWnd);
			return 0;								
		} break;
	}
	return DefWindowProc(hWnd,uMsg,wParam,lParam);
}

Problem: New Window doesnt show up.

Hope there are some win32 experts out there.

Thanks,

It works now, guys never forget:

+ Code Snippet

//Attempt to register the window class
	if ( !RegisterClass(&WC) )
		MessageBox(NULL,"Failed To Register Window Class.","ERROR",MB_OK|MB_ICONEXCLAMATION);
