Abort and Dispose Transaction

[SRSDS]

This must be important but I don't understand the difference between the two.

You shouldn't ever explicitly need to call Abort. If the Transaction is Disposed before you call Commit, then it calls Abort internally. Just make sure you Dispose of the Transaction immediately you've finished with it - never leave it to be garbage collected.

        ' This will ensure that it is automatically disposed of.

        Using db As Database = HostApplicationServices.WorkingDatabase()
            Using tr As Transaction = db.TransactionManager.StartTransaction
                Dim myDWG As Document = Autodesk.AutoCAD.ApplicationServices.Application.DocumentManager.MdiActiveDocument
                Using lock As DocumentLock = myDWG.LockDocument
                    ' ... Do stuff
                    tr.Commit()
                End Using
            End Using
        End Using
