Bitmaps i C++

Er det noget i stil med dette du er ude efter:
void OnDraw(HWND hwnd)
{
  PAINTSTRUCT PaintStruct;
  BeginPaint(hwnd, &PaintStruct);
  HFONT Font = CreateFont(16, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, "Arial");
  HDC dc = PaintStruct.hdc; // The screen Device Context

  HDC MemDc = CreateCompatibleDC(dc);                    // And a memory DC compatible with the screen DC
  SelectObject(MemDc,  Font);                            // Tell windows that we want to use the font when drawing on the DC
  HBITMAP Bitmap = CreateCompatibleBitmap(dc, 200, 100); // Now create a Ditmap
  HGDIOBJ OldBitmap = SelectObject(MemDc,  Bitmap);      // Use the Bitmap with the memory DC
  HBRUSH Brush = CreateSolidBrush(RGB(255, 128, 128));  // Create a light red brush
  RECT Rect = {0, 0, 200, 100};
  FillRect(MemDc, &Rect, Brush);                        // Fill the background of the bitmap with brush
  SetBkMode(MemDc, TRANSPARENT);                        // Don't draw background while drawing text.
  TextOut(MemDc, 5, 5, "Whatever", 8);                  // Put some text
  HPEN Pen = CreatePen(PS_SOLID, 1, RGB(0, 0, 255));    // Create a blue pen
  HGDIOBJ OldPen = SelectObject(MemDc, Pen);            // Tell windows to use the pen with this DC
  MoveToEx(MemDc, 0, 0, 0);                              // Move to upper left corner
  LineTo(MemDc, 199, 0);                                // Draw some lines
  LineTo(MemDc, 199, 99);
  LineTo(MemDc, 0, 99);
  LineTo(MemDc, 0, 0);

  BitBlt(dc, 10, 10, 200, 100, MemDc, 0, 0, SRCCOPY);    // Copy everything to the screen

  SelectObject(MemDc,  OldBitmap);                      // Cleanup
  SelectObject(MemDc,  OldPen);                          // Cleanup
  EndPaint(hwnd, &PaintStruct);
  DeleteDC(MemDc);
  DeleteObject(Font);
  DeleteObject(Brush);
  DeleteObject(Bitmap);
  DeleteObject(OldPen);
}

Der er en hel applikation der bruger det her:

Hvis du bruger MFC vil du nok bruge nogle class'er, så som CDC, CBitmap, CPen etc. men fremgangsmåden er den samme.

Det er SUPERT!
Det er praecist hvad jeg soeger efter!
Mange tak!
