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.
DTN_CLOSEUP lpNmhdr = (LPNMHDR)lParam;
Parameters
- lpNmhdr
Long pointer to an NMHDR structure that contains information about the message.
Return Values
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.
Requirements
OS Versions: Windows CE 2.0 and later.
Header: Commctrl.h.
