Notes to Implementers

Implement this interface on the language service object to allow your language service to provide data tips, word extent, pair extent, and formatting.

Notes to Callers

Obtain this interface by asking the language service for it through the QueryService method. For example:

    public IVsLanguageTextOps GetTextOps(Microsoft.VisualStudio.OLE.Interop.IServiceProvider provider,
Guid languageServiceGuid)
    {
        IVsLanguageTextOps textOps = null;
        textOpts = provider.QueryService(languageServiceGuid,
                                         typeof(IVsLanguageTextOps).GUID)
                                as IVsLanguageTextOps;
        return textOpts;
    }
