Public Function IsValidType (pBuffer As IVsTextLines, ts As TextSpan(), rgTypes As String(), iCountTypes As Integer, ByRef pfIsValidType As Integer) As Integer

Parameters

pBuffer: IVsTextLines

[in] An IVsTextLines object that represents the text buffer where the code snippet is to be inserted.

ts: TextSpan[]

[in] A TextSpan object that describes the location where the code snippet is to be inserted.

rgTypes: String[]

[in] An array strings specifying the types of the code snippet to be inserted. This can be a null value if iCountTypes is 0. See Remarks.

iCountTypes: Int32

[in] The number of types specified in the rgTypes array.

pfIsValidType: Int32

[out] Non-zero (TRUE) if the code snippet can be inserted into the specified location based on its types; zero (FALSE) if the code snippet cannot be inserted.

Returns

Int32

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

Remarks

COM Signature

From textmgr2.idl:

bool IVsExpansionClient::IsValidType(  
   [in]IVsTextLines *pBuffer,  
   [in]TextSpan *ts,  
   [in, size_is(iCountTypes)]BSTR* rgTypes,  
   [in] int iCountTypes  
);

The rgTypes list contains strings that specify the types of snippets to display. These types can be "Expansion" or "SurroundsWith" (see SnippetType Element (Intellisense Code Snippets) for details on snippet types). It is possible for a code snippet to not have a type associated with it, in which case the iCountTypes parameter is 0.
