This API function shows or hides all pop-up windows owned by the given window. This eliminates the need to call ShowWindow() for each individual pop-up window.
To use it with Clipper, simply add this command line in one .prg file of you application :
DLL FUNCTION ShowOwnedPopups( nHwnd AS _INT, bShow AS BOOL ) AS BOOL PASCAL FROM "ShowOwnedPopups" LIB "USER.EXE"
Hope this help,
