Remarks
If your language service supports additional commands than those supported by the ViewFilter class, then you must derive a class from the ViewFilter class and override this method. Determine if your commands are supported first and then call the base method if the command is unrecognized.
The base method obtains the expansion provider and if a template is currently being edited, calls the HandleQueryStatus method on the ExpansionProvider class. If HandleQueryStatus returns true
, then the base method returns the code from HandleQueryStatus. Otherwise, the base method reports that all the commands supported by the base ViewFilter class are supported — if certain conditions apply (see the command table below). The base method returns OLECMDERR_E_UNKNOWNGROUP if a command is not supported.
The following table lists the commands and the properties that must be set for the command to be supported.
