VS_GrabScr() Captures the contents of the screen
Description:
VS_GrabScr() is actually nothing more than a greatly improved version
of Clipper's 'SAVE SCREEN' command. VS_GrabScr() captures not only the
screen image, but also the screen attributes, cursor location, etc.
VS_GrabScr() is designed to be used in conjunction with VS_PutScr()
and VS_DropScr().
Syntax:
VS_GrabScr()
Pass:
Nothing
Return:
VS_GrabScr() always returns NIL.
Notes:
Example:
VS_GRABSCR()
ac_msg[1] = "Please wait while printing"
VS_MSG(ac_msg,1,"","")
DO RPT_PRGM
VS_PUTSCR()
Usage:
Clipper's SAVE SCREEN command doesn't quite fit the bill for most
screen save operations. i.e. it doesn't save the cursor location or
screen attributes (colors). VS_GRABSCR() saves all of these very
important aspects of your screen and will restore them properly when
you call VS_PUTSCR().
