A client application should notify the client DLL when it opens, closes, saves, or renames a document, or reverts a document to a previously saved state. A client application can use the following functions to accomplish these tasks:
| Function | Description |
| OleRegisterClientDoc | Registers an opened document with the client DLL. |
| OleRenameClientDoc | Informs the client DLL that a document has been renamed. |
| OleRevertClientDoc | Informs the client DLL that a document has reverted to a previously saved state. |
| OleRevokeClientDoc | Informs the client DLL that a document should be closed or no longer exists. |
| OleSavedClientDoc | Informs the client DLL that a document has been saved. |
Note When saving an object, the client application must store a persistent name for that object in its document file; this name uniquely identifies the object. The application must retain the name until the object is explicitly renamed with the OleRename function or until the object is deleted with the OleDelete function. Since this name is used to locate the object, it should be stored separate from the object itself.
