| BOOL AnyPopup(void) |
The AnyPopup function indicates whether an unowned, visible, top-level pop-up, or overlapped window exists on the screen. The function searches the entire Windows screen, not just the caller's client area.
This function has no parameters.
The return value is TRUE if a pop-up window exists, even if the pop-up window is completely covered by other windows. Otherwise, it is FALSE.
AnyPopup is a Windows 1.x function and remains for compatibility reasons. It is generally not useful.
This function does not detect unowned pop-up windows or windows that do not have the WS_VISIBLE style bit set.
