DTN_DROPDOWN (Compact 2013)
3/28/2014
This message is sent by a date and time picker (DTP) control when the user activates the drop-down month calendar.
Syntax
DTN_DROPDOWN 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 creates a new month calendar control before sending this message. Additionally, the DTP control destroys the child control when it is not active (visible). Therefore, your application must not rely on a static window handle for the control's child month calendar.
