I have not found any good examples of how to do this anywhere. I do find plenty of references to Block Attributes, which does not interest me, particularily because Im using Map. All I need to do really is to be able to populate a variable with object data from a single selected item. Ive figured already that I need a reference to the Autocad Map library. The program Im writing will connect to a MS SQL database using ADO, which is the easy part, the hard part is finding good examples of referencing Autocad Map object data.
