User32CalculatePopupWindowPosition Method

Calculates an appropriate pop-up window position using the specified anchor point, pop-up window size, flags, and the optional exclude rectangle.

When the specified pop-up window size is smaller than the desktop window size, use the CalculatePopupWindowPosition(NativePoint, NativeSize, PopupWindowPositionFlags, NativeRectangle, NativeSize) function to ensure that the pop-up window is fully visible on the desktop window, regardless of the specified anchor point.
