COleServerItem

The COleServerItem class provides the server interface to OLE items. A linked item can represent some or all of a server document. An embedded item always represents an entire server document.

The COleServerItem class defines several overridable member functions that are called by the OLE system dynamic-link libraries (DLLs), usually in response to requests from the container application. These member functions allow the container application to manipulate the item indirectly in various ways, such as by displaying it, executing its verbs, or retrieving its data in various formats.

To use COleServerItem, derive a class from it and implement the OnDraw and Serialize member functions. The OnDraw function provides the metafile representation of an item, allowing it to be displayed when a container application opens a compound document. The Serialize function of CObject provides the native representation of an item, allowing an embedded item to be transferred between the server and container applications. OnGetExtent provides the natural size of the item to the container, enabling the container to size the item.
