If I select the Image Properties from the Conext Menu in the demo program I get the first attached dialog whereas if I do the same in my Photo Gallery application I get the second, after the error message referred to in my earlier post, so something isn't working!
If I copy my .exe to the graphicsDemoNoData program folder and run it from there I get the same error and then the third attached dialog which is at least trying to show some properties.
BTW I didn't have to register the .ocx in your Example Workspace. Did the installer do it?
