IOleCommandTarget interface

Enables objects and their containers to dispatch commands to each other. For example, an object's toolbars may contain buttons for commands such as Print, Print Preview, Save, New, and Zoom.

Normal in-place activation guidelines recommend that you remove or disable such buttons because no efficient, standard mechanism has been available to dispatch them to the container. Similarly, a container has heretofore had no efficient means to send commands such as Print, Page Setup, and Properties to an in-place active object. Such simple command routing could have been handled through existing OLE Automation standards and the IDispatch interface, but the overhead with IDispatch is more than is required in the case of document objects. The IOleCommandTarget interface provides a simpler means to achieve the same ends.

Available commands are defined by integer identifiers in a group. The group itself is identified with a GUID. The interface allows a caller both to query for support of one or more commands within a group and to issue a supported command to the object.


The IOleCommandTarget interface inherits from the IUnknown interface. IOleCommandTarget also has these types of members:


The IOleCommandTarget interface has these methods.


Executes the specified command or displays help for the command.


Queries the object for the status of one or more commands generated by user interface events.
