Before you begin:
Call this code from a VFP form to store its snapshot to a bitmap file (24-bpp). Make sure that the target file (m.lcFilename) is a valid path.

    My comment:
    The resulting file is forced to be in 24-bit format (24 bits per pixel). It is not compressed.

    The part of DIB (Device-Independent Bitmap), that contains pixel data, can be too large for managing it via VFP strings. For that reason the GlobalAlloc/GlobalFree combination is used to allocate/release memory for this buffer.

    The WriteFile function is declared in two different ways: one for strings and another for pointers.
