I create a MFC single dialog project on vs2010, and insert eDrawings 2014 Control to the dialog, but the control only shows document performance view, no menubar or toolbars displayed, I want to make at least markup toolbar Visible, and get the markup interface by “cocreateinstance” , the markup interface have  a  "enableFeatures" property, I can get the property by getIDsOfName but I can't get the set/put/get func in the interface to set features. I just want to make the markup toolbar Visible, anyone knows how to do?
