[quote user="Maury"] I am assuming that you are referring to a DgnPrimitiveTool[/quote]
The problem we face here is that DgnPrimitiveTool is not documented. However, we might assume that it's a wrapper around the C++ DgnElementSetTool class or one of its relatives. However, I don't see an accept keyin option or method in that class.
On the other hand, VBA for CONNECT retains the Keyin event handler in the IPrimitiveCommandEvents interface. It's not clear how one would anticipate a user key-in using C++.
