Function Reference


Retrieves the handle to child month calendar control

#include <GuiDateTimePicker.au3>
_GUICtrlDTP_GetMonthCal ( $hWnd )


$hWnd Handle to the control

Return Value

Success: the month calendar handle.
Failure: 0


DTP controls create a child month calendar control when the user clicks the drop down arrow ($DTN_DROPDOWN notification).
When the month calendar is no longer needed, it is destroyed (a $DTN_CLOSEUP notification is sent on destruction).
So your application must not rely on a static handle to the DTP control's child month calendar.
