DTM_GETMONTHCAL message

Gets the handle to a date and time picker's (DTP) child month calendar control. You can send this message explicitly or use the DateTime_GetMonthCal macro.

Parameters

wParam
Must be zero.
lParam
Must be zero.

Return value

Returns the handle to a DTP control's child month calendar control if successful, or NULL otherwise.

Remarks

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.
