Right after the CreateWindow call which places an empty 320x240 window in the center of the screen I''m attempting to load a bitmap on to that window with BeginPaint and the HDC to create a splash screen that displays while all the DirectX components load up. At hDC = BeginPaint(m_hWnd, &ps), a second area of 320x240 is created in the top left corner of the screen and the bitmap shows up both where it''s supposed to and in that top left corner.

  
//load bitmap to initial window

HBITMAP splash;
PAINTSTRUCT	ps;
HDC		hDC;

splash= (HBITMAP)LoadImage(NULL, "graphics/loadlogo.bmp", IMAGE_BITMAP, 0, 0, LR_LOADFROMFILE);
hDC = BeginPaint(m_hWnd, &ps);
DrawState(hDC, NULL, NULL, (LPARAM)splash, 0, 0, 0, 320, 240, DST_BITMAP | DSS_NORMAL);
EndPaint(m_hWnd, &ps);
delete(splash);

What does DrawState() do?

Your code looks right to me, so I don''t know whats causing your problem.
But maybe you should try a different drawing method. GetWindowDC + BitBlt might work better.

DrawState actually puts the bitmap to the screen. Even if I take that out there are still two empty white windows on the screen.

I tried using TextOut as well and the text showed up in both windows also.

Per MSDN:


DrawState
The DrawState function displays an image and applies a visual
effect to indicate a state, such as a disabled or default state.


BOOL DrawState(
  HDC hdc,                     // handle to device context
  HBRUSH hbr,                  // handle to brush
  DRAWSTATEPROC lpOutputFunc,  // callback function
  LPARAM lData,                // image information
  WPARAM wData,                // more image information
  int x,                       // horizontal location
  int y,                       // vertical location
  int cx,                      // image width
  int cy,                      // image height
  UINT fuFlags                 // image type and state
);

I don't quite understand what you mean here...

how can you have a second area of 320x240 when the window is only 320x240? Is this going to end up being full screen? Or is a windowed app? Are you initializing DX while this is being displayed? Are you sure it is only drawing the the window created for a splash and not your DX window?

Always remember, you''re unique. Just like everyone else.

Edit: Minor visual edit...

Fixed it. The call to go to full screen was being made before it was really ready. I thought it was taking care of more than it was before that point.
