Description
A CommandItem class represents any item on a command bar. For example, buttons, tools, and menu items that appear on command bars are all command items. Use the Find method from either ICommandBars or ICommandBar to obtain a reference to a particular CommandItem.
Supported Platforms
Extended Error Information
Use the ISupportErrorInfo method InterfaceSupportsErrorInfo to determine if the object supports extended error information. If the object supports extended error info, VC++ developers should use the OLE/COM IErrorInfo interface to access the ErrorInfo object. Visual Basic developers should use the global error object Err to retrieve this extended error information.
