Syntax

Parameters
lpNmhdr
Long pointer to an NMHDR structure that contains information about the notification message.
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 notification. Therefore, your application must not rely on a static window handle for the control’s child month calendar.

The return value for this notification is not used.
