Bonjour, dans mon programme je voudrai placer un fond d'écran (à partir d'un BMP), plus précisement ceci dans ma HWND principale, en traitant le message WM_PAINT, voici le code :

case WM_PAINT:
        hDC = BeginPaint(hWnd, &Ps);
        hMemDC = CreateCompatibleDC(hDC);

        hBitmap = LoadBitmap(g_hInstance, MAKEINTRESOURCE(1337));
        if(hBitmap != NULL) MessageBox(hWnd, "Bitmap Chargé Valide !", "_DEBUG", MB_OK);

        SelectObject(hMemDC, hBitmap);
        BitBlt(hDC, 0, 0, 350, 350, hMemDC, 0, 0, SRCCOPY);

        DeleteDC(hMemDC);
        CloseHandle(hBitmap);
        EndPaint(hWnd, &Ps);
        break;

Le background est correctement copié sur ma fenêtre, tellement bien copié qu'on y voit même plusmes contrôles ! Je peux revoir un bouton si je clique dessus par exemple, sinon rien du tout, la totalité des contrôles n'est plus visible. J'aimerais un peu d'aide...

Merci beaucoup.

Il vaut mieux utliser le message WM_ERASEBKGND pour changer le fond
sinon quand j'ai eu ce probleme j'ai utlisé ce code juste apres

        //Rafraichissement des controls pour éviter qu'ils passent sous l'image

        HWND titest2;

        titest2 = ::FindWindowEx(hwnd,NULL,NULL,NULL);

        RECT retest;

        GetWindowRect(hwnd,&retest);

        while (::FindWindowEx(hwnd,titest2,NULL,NULL) != NULL) {

            titest2 = FindWindowEx(hwnd,titest2,NULL,NULL);

            ::GetWindowRect(titest2,&retest);

            ::InvalidateRect(titest2,NULL,false);

        }
