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,

Thanks for the info,

ShowOwnedPopups(hWnd, .F.) return not always .T. when there is not
Owned popups for the window, depending on unknown reason.
Problem found on a pc with XP Home edition.
