After a bit more exploration I found that I had indeed missed something: If you right click on menu items and select the "add event handler" option, the Event Handler Wizard appears and gives you the option to create or edit COMMAND and UPDATE_COMMAND_UI messages - so that's where they're hidden! The rule seems to be: right click on the thing you want to create a handler for and the Event Handler Wizard will provide pretty much the same functionality as MFC's ClassWizard - except that it doesn't work for toolbar buttons because you don't get an opportunity to call it up. I suppose one way round this is always to build a menu item first, attach handlers to it, then build a toolbar button with the same ID - and it will share the same handlers. Perhaps it is good practice to replicate every toolbar function in a menu, so maybe this approach makes sense. On the other hand, I don't see why a right click on the toolbar shouldn't offer the "add event handler" option. The treatment of toolbar buttons seems inconsistent with that of menu items and dialog buttons. Best Regards Cliff
