This message indicates that the user chose the OK or Apply Now button and wants all changes to take effect. It is sent in the form of a WM_NOTIFY message.

Parameters

• lppsn
  Long pointer to a PSHNOTIFY structure that contains information about the notification.

Remarks

The PSHNOTIFY structure contains an NMHDR structure as its first member, hdr. The hwndFrom member of this NMHDR structure contains the handle to the property sheet.

To set the return value, the dialog box procedure for the page must use the SetWindowLong function with the DWL_MSGRESULT value, and the dialog box procedure must return TRUE.

The property sheet is destroyed if the user clicks the OK button and the application returns the PSNRET_NOERROR value in response to this notification.
