How to Create Cascading Menus with the IExplorerCommand Interface

Another option for adding verbs to a cascading menu is through IExplorerCommand::EnumSubCommands. This method enables data sources that provide their command module commands through the IExplorerCommandProvider interface to use those commands as verbs on a shortcut menu. In Windows 7 and later, you can provide the same verb implementation using the IExplorerCommand interface as you can with the IContextMenu interface.

Instructions

Remarks

Note  Because IExplorerCommand supports in-process activation only, it is recommended for use by Shell data sources that need to share the implementation between commands and shortcut menus.
