ExpansionProvider.IsValidType Method
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.

Public Overridable Function IsValidType ( _

) As Integer
public virtual int IsValidType(
IVsTextLines buffer,
TextSpan[] ts,
string[] rgTypes,
int iCountTypes,
out int fIsValid
)
Parameters
- buffer
Type: Microsoft.VisualStudio.TextManager.Interop.IVsTextLines
The IVsTextLines buffer.
- ts
Type: array<Microsoft.VisualStudio.TextManager.Interop.TextSpan[]
An array of TextSpan objects.
- rgTypes
Type: array<System.String[]
An array of expansion types.
- iCountTypes
Type: System.Int32
The number of expansion types in the rgTypes array.
- fIsValid
Type: System.Int32%
[out] Returns true if the type is valid, otherwise false.
Return Value
Type: System.Int32
When overridden in derived classes, S_OK if the method succeeds, otherwise an error code.
Implements
IVsExpansionClient.IsValidType(IVsTextLines, array<TextSpan[], array<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.
