Persistence of OLE Controls
One capability of OLE controls is property persistence (or serialization), which allows the OLE control to read or write property values to and from a file or stream. A container application can use serialization to store a control's property values even after the application has destroyed the control. The property values of the OLE control can then be read from the file or stream when a new instance of the control is created at a later time.
