Problem:

How to capture a screenshot of a window into a bitmap

Resolution:

You have to use this syntax:

CALL "W$BITMAP"

    USING WBITMAP-CAPTURE-IMAGE,

          "C:\AcuSamples\bitmap\Resource\image.bmp",

          0, | 0 = active window is captured

          0, | 0 = The entire window is captured, including the title bar, window frame, menu, etc.

          1, | 1 = monochrome, 32 = 32-bits per pixel  

    GIVING w-BITMAP-HANDLE

If W-BITMAP-HANDLE = 1, you will find your screenshot in the saved .bmp file.
