Parameters

  • pszMkDocument
    Type: String

    [in] Path to the document.

  • punkDocData
    Type: IntPtr

    [in] The IUnknown interface of the document. A null value indicates no document object that can be persisted.

  • pdwCookie
    Type: UInt32%

    [out] Returns an abstract value representing the document in the RDT.

Return Value

Type: Int32
If the method succeeds, it returns S_OK. If it fails, it returns an error code.

Remarks

COM Signature

From vsshell.idl:

HRESULT IVsRunningDocumentTable::RegisterAndLockDocument(
   [in] VSRDTFLAGS    grfRDTLockType,
   [in] LPCOLESTR     pszMkDocument,
   [in] IVsHierarchy *pHier,
   [in] VSITEMID      itemid,
   [in] IUnknown     *punkDocData,
   [out] VSCOOKIE    *pdwCookie
);

The punkDocData parameter represents the document data object to be registered. Whatever package that calls the RegisterAndLockDocument method creates that document object which must implement at the very least the IVsPersistDocData and IVsDocDataFileChangeControl interfaces.
