    Question Multi-BMP Loading Problem!(PLEASE HELP!)

    I am working onskinning my own window, instead of those same old dull regular windows. I made a BMP for the title bar, minimize button, and close button. I need help, though. I try this:


    void DrawTBar(HDC hdc)
    {
    HDC hdcMemory;
    hdcMemory = CreateCompatibleDC(hdc);

    SelectObject(hdcMemory, dBar);
    BitBlt(hdc, tBarX, tBarY, ((514 - 26) - 26) - 26, bm.bmHeight, hdcMemory, 0, 0, SRCPAINT);

    DeleteDC(hdcMemory);
    }
    void DrawMBtn(HDC hdc)
    {
    HDC hdcMemory;
    hdcMemory = CreateCompatibleDC(hdc);

    SelectObject(hdcMemory, dBar);
    BitBlt(hdc, mnX, mnY, mn.bmWidth, mn.bmHeight, hdcMemory, 0, 0, SRCPAINT);

    DeleteDC(hdcMemory);
    }
    void DrawCBtn(HDC hdc)
    {
    HDC hdcMemory;
    hdcMemory = CreateCompatibleDC(hdc);

    SelectObject(hdcMemory, dBar);
    BitBlt(hdc, csX, csY, cs.bmWidth, cs.bmHeight, hdcMemory, 0, 0, SRCPAINT);

    DeleteDC(hdcMemory);
    }



    Then in WM_PAINT:


    case WM_PAINT:
    PAINTSTRUCT ps;
    PAINTSTRUCT ps2;
    PAINTSTRUCT ps3;
    HDC hdcWindow;
    HDC hdc2;
    HDC hdc3;

    hdcWindow = BeginPaint(hwnd, &ps);

    DrawTBar(hdcWindow);

    EndPaint(hwnd, &ps);

    hdc2 = BeginPaint(hwnd, &ps2);

    DrawMBtn(hdc2);

    EndPaint(hwnd, &ps2);

    hdc3 = BeginPaint(hwnd, &ps3);

    DrawCBtn(hdc3);

    EndPaint(hwnd, &ps3);
    break;



    It only loads the title bar image. How do I load multiple bitmaps?

    Use a frame buffer.

    Your paint is the problem as it is not the right hdc / paintstruct.

    I posted a paint function before and mentioned the memory you are loosing with incorrect use of selectobject().

    Work it out, I think you will learn more from discovering a way through.

    Isn't here a little mistake?

    BeginPaint validates update region and clears client window area by a brush stored in WNDCLASS. Three subsequent BeginPaint () calls therefore are unnecessary, only the last call has sense.

    Actually I think only the first.

    After that the update region is now valid and so no more paint will take place.

    Problem is to get all the regions, that need a redraw, to draw at the same time.

    Or to find the correct hdc to draw onto.

    Hmm, it might be the first.

    While there is no invalid area, BeginPaint () does no clearing.
    Seems it was my mistake.

    The BeginPaint validates the update region. Further calls will fail.

    Try putting all the draw functions in the same paint. Not the correct way do to a paint but may fix the problem.
