    GetDC (to find a DC for the location to draw)

    CreateCompatibleDC (get one of your own)

    CreateCompatibleBitmap (or use yours)

    SelectObject (to get the BMP into the HDC catching the return to put back when you finish)

    ReleaseDC (on the GetDC)
    May need SetDIBits and SetStretchBltMode

    BitBlt or StretchBlt to the frame buffer DC

    BitBlt (in the paint function to the paintstruct DC)

    DeleteDC on exit after SelectObject back so the HDC is exactly as you created it. Else you will lose GDI resources.

    I also stack a BITMAPINFOHEADER struc but I am loading jps from mem or off the drive so I am not sure if you need it.

    Easy OK?
