Parameters

pSnippet
Type: IXMLDOMNode
[in] Contains the code snippet text.

tsInsertPos
Type: Microsoft.VisualStudio.TextManager.Interop.TextSpan
[in] The location in the text buffer to insert the code snippet.

pExpansionClient
Type: Microsoft.VisualStudio.TextManager.Interop.IVsExpansionClient
[in] Receives notifications about the insertion process. This can be nulla null reference (Nothing in Visual Basic).

guidLang
Type: System.Guid
[in] The GUID of the language service. Can be nulla null reference (Nothing in Visual Basic). The default is the language service of the file.

pszRelativePath
Type: System.String
[in] A path that is used if the node references an external file. This is typically nulla null reference (Nothing in Visual Basic).

pSession
Type: Microsoft.VisualStudio.TextManager.Interop.IVsExpansionSession%
[out] The session that is used while the snippet is being edited in place.

Return Value

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

Remarks

COM Signature

From textmgr2.idl:

HRESULT IVsExpansion::InsertSpecificExpansion(
   [in]IXMLDOMNode *pSnippet,
   [in] TextSpan tsInsertPos,
   [in]IVsExpansionClient *pExpansionClient,
   [in]GUID guidLang,
   [in] BSTR pszRelativePath,
   [out] IVsExpansionSession **pSession
);

This method is used only if you are working directly with code snippet files and is rarely used.

If an IVsExpansionClient object is supplied, it receives before (OnBeforeInsertion method) and after (OnAfterInsertion method) notifications during the insertion process. The expansion client is also used to validate the kind of snippet (IsValidKind method) to make sure the snippet can actually be inserted at the specified location.
