Is there a way to import an object created with a 3d-modeling program (ex. Google Sketchup) to an OpenGL application and use it?

What type of image is the source image?

How are you looking at the actual colors in the HBITMAP?

   HBITMAP bmp;
   if (Gdiplus::Ok == SrcBitmap.GetHBITMAP(clr, &bmp))
   {
//      BITMAP bitmapstruct;
//      GetObject((HGDIOBJ)bmp, sizeof(BITMAP), &bitmapstruct);
 
      HDC hMemDC = ::CreateCompatibleDC(0);
      HDC hDestDC = ::GetDC(*this);

      ::SelectObject(hMemDC, hOldBitmap);
 
      ::ReleaseDC(*this, hDestDC);
      ::DeleteDC(hMemDC);
       ::DeleteObject((HGDIOBJ)bmp);

As I doubt it is our fault I am going to go with the flawed theory.

I posted sample code on MS site as well just for the heck of it.

Anyway, did you draw any conclusion from all that?
