This message notifies a page that it is about to lose the activation either because another page is being activated or the user has chosen the OK button. It is sent in the form of a WM_NOTIFY message.

Syntax

PSN_KILLACTIVE lppsn = (LPPSHNOTIFY) lParam;

Parameters

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

Return Value

TRUE to prevents the page from losing the activation. FALSE allows the page to lose activation.

Remarks

The lParam member of this structure does not contain any information.

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.

An application should validate the information the user has typed.

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.
