The following code example shows the OLESERVERVTBL data structure as defined in OLE.H. This structure points to application-specific callback functions that are used to manipulate a server application. After a server application creates this structure and a corresponding OLESERVER structure (which points to OLESERVERVTBL), the server DLL can make calls to the server application.
typedef struct _OLESERVERVTBL
{
OLESTATUS (CALLBACK* Open) (LPOLESERVER, LHSERVERDOC, OLE_LPCSTR,
LPOLESERVERDOC FAR*);
OLESTATUS (CALLBACK* Create)(LPOLESERVER, LHSERVERDOC, OLE_LPCSTR,
OLE_LPCSTR, LPOLESERVERDOC FAR*);
OLESTATUS (CALLBACK* CreateFromTemplate)(LPOLESERVER, LHSERVERDOC,
OLE_LPCSTR, OLE_LPCSTR,
OLE_LPCSTR, LPOLESERVERDOC
FAR*);
OLESTATUS (CALLBACK* Edit) (LPOLESERVER, LHSERVERDOC, OLE_LPCSTR,
OLE_LPCSTR, LPOLESERVERDOC FAR*);
OLESTATUS (CALLBACK* Exit) (LPOLESERVER);
OLESTATUS (CALLBACK* Release) (LPOLESERVER);
OLESTATUS (CALLBACK* Execute)(LPOLESERVER, HGLOBAL);
} OLESERVERVTBL;
The following table lists the OLESERVERVTBL data structure members; each member points to a specific callback function.
| Structure | MemberDescription |
| Open | Opens an existing document in preparation for editing. |
| Create | Opens a new document. |
| CreateFromTemplate | Creates a new document and initializes it with the data from a specified file. |
| Edit | Creates a document that is initialized with data retrieved by a subsequent call to the SetData function. |
| Exit | Instructs the server application to close documents and terminate (simply terminate if no documents are registered). |
| Release | Notifies a server that all connections to it have closed and that it is safe to terminate. |
| Execute | Specifies DDE execute strings. |
