DTN_CLOSEUP

DTN_CLOSEUP
    lpNmhdr = (LPMNHDR)lParam;

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.

• The return value for this notification is not used.

lpNmhdr

Address of an NMHDR structure that contains information about the notification message.

DTP controls do not maintain a static child month calendar control. The DTP control destroys the child month calendar control prior to sending this notification. So your application must not rely on a static window handle for the control's child month calendar.

Version 4.70
