AnyPopup function (winuser.h)
Indicates whether an owned, visible, top-level pop-up, or overlapped window exists on the screen. The function searches the entire screen, not just the calling application's client area.
This function is provided only for compatibility with 16-bit versions of Windows. It is generally not useful.
If a pop-up window exists, the return value is nonzero, even if the pop-up window is completely covered by other windows.
If a pop-up window does not exist, the return value is zero.
This function does not detect unowned pop-up windows or windows that do not have the WS_VISIBLE style bit set.
