Remarks
Implement this interface to provide custom information about a language block for your language. The definition of a language block is particular to each programming language. For example, a language block in Visual Basic extends from the Sub command to the End Sub command as shown in the following example:
Private Sub SubroutineName()
End Sub
Language block information is typically used with the Find command to confine a search to a single function or method. This interface is also used to select an entire method when the user double-clicks in the selection margin.
Notes to Implementers
Implement this interface on the language service object to provide information about a language block within the core text editor.
Notes to Callers
Obtain this interface by asking the language service for it through the QueryService method. For example:
public IVsLanguageBlock GetTextOps(Microsoft.VisualStudio.OLE.Interop.IServiceProvider provider,
Guid languageServiceGuid)
{
IVsLanguageBlock languageBlock = null;
languageBlock = provider.QueryService(languageServiceGuid,
typeof(IVsLanguageBlock).GUID)
as IVsLanguageBlock;
return languageBlock;
}
