Removing all custom handlers of an event
By Augusto Goncalves In some scenarios, we may add more than one handler for a specific event. In this case, AutoCAD will throw it several times. Imagine a code like the one below, where for the Document object we add 2 handlers duplicated, and another different. <CommandMethod("addEvents")> _ ...

Ben,
I believe the other way would be to PASTE SPECIAL, which creates an OLE object. I'm afraid this is not exposed as an API, you may be able to use P/Invoke as shown here http://adndevblog.typepad.com/autocad/2012/04/update-linked-ole-object-from-net.html

I don't believe you can change this ID, it's read-only and not a parameter while creating the align entity. That's where this approach comes in: remove and replace ensuring the previous and next remains.

Rodrigo, this sample is in C++ (so it doesn't uses packages), but you need to compile it using the COM references. It also should not require you to start AutoCAD (as it uses only the COM API for Dwg Props). Finally the VS Community doesn't include MFC (I believe) that is required for CString (among other Windows features).
