Must be one of the following: Value Meaning OLE_CHANGED The server item's state has changed (as from editing). OLE_SAVED The server document that contains this item was saved. OLE_CLOSED The server document that contains this item was closed. Remarks This is a pure virtual callback function that you must implement in your derived class. It is called by OLECLI.DLL when the server changes an OLE item. In general, do not redraw the client item when you get the OnChange callback, but instead post an update message or use CWnd::InvalidateRect for the window. -♦-
