Voila , je cree une app en directdraw et affiche un bitmap, en plein ecran c impec, mais en mode fenetre ca rame (jaurais oublie qqch ???)
 

Code :
  1. DDSURFACEDESC ddsd;
  3. if( FAILED( DirectDrawCreate(NULL, &pDD, NULL))){
  4.  MessageBox(NULL,"DirectDrawCreate() failed","ERROR",MB_OK|MB_ICONEXCLAMATION);
  5.  return false;
  6. }
  8. if( FAILED( pDD->SetCooperativeLevel(hWnd, DDSCL_NORMAL))){
  9.  MessageBox(NULL,"SetCooperativeLevel() failed","ERROR",MB_OK|MB_ICONEXCLAMATION);
  10.  return false;
  11. }
  13. ZeroMemory(&ddsd, sizeof(ddsd));
  14. ddsd.dwSize = sizeof(ddsd);
  15. ddsd.dwFlags = DDSD_CAPS ;
  16. ddsd.ddsCaps.dwCaps = DDSCAPS_PRIMARYSURFACE;
  19. if( FAILED( pDD->CreateSurface(&ddsd, &pDDSPrim, NULL))){
  20.  MessageBox(NULL,"CreatePrimarySurface() failed","ERROR",MB_OK|MB_ICONEXCLAMATION);
  21.  return false;
  22. }
  24. if( FAILED(pDD->CreateClipper( 0, &pDDClip, NULL ))){
  25.  MessageBox(NULL,"CreateClipper() failed","ERROR",MB_OK|MB_ICONEXCLAMATION);
  26.  return false;
  27. }
  29. if( FAILED(pDDClip->SetHWnd( 0, hWnd ))){
  30. MessageBox(NULL,"SetHWnd() failed","ERROR",MB_OK|MB_ICONEXCLAMATION);
  31.  return false;
  32. }
  35. if( FAILED(pDDSPrim->SetClipper( pDDClip ))){
  36. MessageBox(NULL,"SetClipper() failed","ERROR",MB_OK|MB_ICONEXCLAMATION);
  37.  return false;
  38. }
  42. ZeroMemory(&ddsd, sizeof(ddsd));
  43.     ddsd.dwSize = sizeof( ddsd );
  44.     ddsd.dwFlags = DDSD_CAPS | DDSD_HEIGHT | DDSD_WIDTH;
  45.     ddsd.ddsCaps.dwCaps = DDSCAPS_OFFSCREENPLAIN;
  46.     ddsd.dwWidth = 640;
  47.     ddsd.dwHeight = 480;
  49.     // create the backbuffer separately
  50.     if( FAILED(pDD->CreateSurface( &ddsd, &pDDSBack, NULL ))){
  51. MessageBox(NULL,"CreateBackSurface() failed","ERROR",MB_OK|MB_ICONEXCLAMATION);
  52.  return false;
  53. }
  54.  
  56. return true;
  58. }
  65. Flip()
  66. {
  68.     RECT rcRectSrc;
  69.     RECT rcRectDest;
  70.     POINT p;
  72.     p.x = 0; p.y = 0;
  73.     ClientToScreen(hWnd, &p);
  74.     GetClientRect(hWnd, &rcRectDest);
  75.     OffsetRect(&rcRectDest, p.x, p.y);
  76.     SetRect(&rcRectSrc, 0, 0, 640, 480);
  78.     pDDSPrim->Blt( &rcRectDest, pDDSBack, &rcRectSrc,DDBLTFAST_WAIT , NULL);
  79.     return false;
  81. }
  83. dans la boucle principale :
  85. SetRect(&rcRect, rand()%50, 0, 640, 480);
  86.  pDDSBack->BltFast( 0, 0, lpDDSOne, &rcRect,DDBLTFAST_NOCOLORKEY | DDBLTFAST_WAIT);
  88.  Flip();
