Determines whether or not a given type is valid for expansion purposes. This method should be overridden if you want to specify where in the source document the expansion can take place.

 virtual int IsValidType(Microsoft::VisualStudio::TextManager::Interop::IVsTextLines ^ buffer, cli::array <Microsoft::VisualStudio::TextManager::Interop::TextSpan> ^ ts, cli::array <System::String ^> ^ rgTypes, int iCountTypes, [Runtime::InteropServices::Out] int % fIsValid);

Public Overridable Function IsValidType (buffer As IVsTextLines, ts As TextSpan(), rgTypes As String(), iCountTypes As Integer, ByRef fIsValid As Integer) As Integer

Parameters

buffer: IVsTextLines

The IVsTextLines buffer.

ts: TextSpan[]

An array of TextSpan objects.

rgTypes: String[]

An array of expansion types.

iCountTypes: Int32

The number of expansion types in the rgTypes array.

fIsValid: Int32

[out] Returns true if the type is valid, otherwise false.

Returns

Int32

When overridden in derived classes, S_OK if the method succeeds, otherwise an error code.

Implements

IsValidType(IVsTextLines, TextSpan[], String[], Int32, Int32)

Remarks

This method by default checks only that buffer is the same as the IVsTextLines of Source; it will throw an ArgumentException if not. Implementers must override this method if they wish to specify where in a document a given expansion can be performed.
