Public Function SaveItem (dwSave As VSSAVEFLAGS, pszSilentSaveAsName As String, itemid As UInteger, punkDocData As IntPtr, ByRef pfCanceled As Integer) As Integer

Parameters

dwSave

VSSAVEFLAGS

[in] Flags whose values are taken from the VSSAVEFLAGS enumeration.

pszSilentSaveAsName

String

[in] File name to be applied when dwSave is set to VSSAVE_SilentSave.

itemid

UInt32

[in] Item identifier of the hierarchy item saved from VSITEMID.

punkDocData

IntPtr

nativeint

[in] Pointer to the IUnknown interface of the hierarchy item saved.

pfCanceled

Int32

[out] true if the save action was canceled.

Returns

Int32

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

Implements

SaveItem(VSSAVEFLAGS, String, UInt32, IntPtr, Int32)

Remarks

COM Signature

From vsshell.idl:

HRESULT IVsPersistHierarchyItem2::SaveItem(  
   [in] VSSAVEFLAGS dwSave,  
   [in] LPCOLESTR pszSilentSaveAsName,  
   [in] VSITEMID itemid,  
   [in] IUnknown *punkDocData,  
   [out] BOOL *pfCanceled  
);  

The caller of this method is responsible for determining whether the document is in the Running Document Table and should pass in the correct punkDocData parameter. It is not necessary for the implementer of this method to call the FindAndLockDocument method when punkDocData is null.

When a document is saved, this method is called to enable the owning hierarchy to establish control. Then the hierarchy can use any private mechanism to persist the document. For hierarchies that use standard editors, the implementation of SaveItem method is to call the following:

• For VSSAVE_Save and VSSAVE_SaveAs, it will QueryInterface for IVsPersistDocData on the document data object and call SaveDocData.

• For VSSAVE_SilentSave, it will QueryInterface for IPersistFileFormat on the document data object and use this interface in a call to the method SaveDocDataToFile passing the parameters VSSAVE_SilentSave, pPersistFile, pszSilentSaveAsNamelpstrUntitledPath, &bstrDocumentNew, and&fCanceled).
