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 NMHDRstructure 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.

Requirements

Header commctrl.h
Windows Embedded CE Windows CE 2.0 and later
Windows Mobile Windows Mobile Version 5.0 and later
