LVN_DELETEALLITEMS Overview  Group

The LVN_DELETEALLITEMS notification message notifies a list view controlís parent window that all items in the control are about to be deleted. This notification message is sent in the form of a WM_NOTIFY message.

LVN_DELETEALLITEMS 

pnmv = (NM_LISTVIEW FAR *) lParam; 

 

Parameters

pnmv
Pointer to an NM_LISTVIEW structure. The iItem member is - 1, and the other members are zero.

Return Values

To suppress subsequent LVN_DELETEITEM notification messages, return TRUE.

To receive subsequent LVN_DELETEITEM notification messages, return FALSE.

Remarks

A list-view control sends the LVN_DELETEALLITEMS notification message when it is destroyed or when it receives the LVM_DELETEALLITEMS message. If LVN_DELETEALLITEMS does not return TRUE, the control will also send an LVN_DELETEITEM notification message as each item is deleted.

If the LVN_DELETEALLITEMS message handler is in a dialog procedure, return TRUE from the dialog procedure, and use the SetWindowLong function with DWL_MSGRESULT to set the message return value.
