LVN_ITEMCHANGED notification code

Notifies a list-view control's parent window that an item has changed. This notification code is sent in the form of a WM_NOTIFY message.

LVN_ITEMCHANGED

    pnmv = (LPNMLISTVIEW) lParam; 

lParam

Pointer to an NMLISTVIEW structure that identifies the item and specifies which of its attributes have changed. If the iItem member of the structure pointed to by lParam is -1, the change has been applied to all items in the list view.

No return value.

If a list-view control has the LVS_OWNERDATA style, and the user selects a range of items by holding down the SHIFT key and clicking the mouse, LVN_ITEMCHANGED notification codes are not sent for each selected or deselected item. Instead, you will receive a single LVN_ODSTATECHANGED notification code, indicating that a range of items has changed state.
