Topic: Get undo call stack in autocad2009

[nileshagresar]

I have used Autodesk.AutoCAD.Internal.Utils.GetUndoHistory() in autocad2010. But could not find the same in Autocad2009.
I have tried to add acmgdinternal.dll in project but it do not produce undohistory().
Any ways by which i can get it in AutoCAD 2009?

Thanks and Regards

Not much is listed on the Autodesk.AutoCAD.Internal.Utils namespace in the Docs IMHO ..
I haven't got a clue how you could duplicate that in the 2009 version of AutoCAD.
