DTN_CLOSEUP
A version of this page is also available for
4/8/2010
This message is sent by a date and time picker (DTP) control when the user closes the drop-down month calendar. The month calendar is closed when the user chooses a date from the month calendar or clicks the drop-down arrow while the calendar is open.
Syntax
DTN_CLOSEUP lpNmhdr = (LPNMHDR) lParam;
Parameters
- lpNmhdr
Long pointer to an NMHDR structure that contains information about the message.
Return Value
The return value for this message is not used.
Remarks
DTP controls do not maintain a static child month calendar control. The DTP control destroys the child month calendar control prior to sending this message. Therefore, your application must not rely on a static window handle for the control's child month calendar.
