What is in the list of your treeview?  Are you listing the objects Handles, ObjectId, or something else?  SelectObjects method takes an array of ObjectIds.  You are passing it a string which will not work.

You can use the Editor.SetImpliedSelection method to select your objects in a drawing.  The method takes an array of ObjectId's.

For instance the following code will clear out the pickfirst selection set.

editor.SetImpliedSelection(New ObjectId() {})

You can do the same thing with the method you are trying to use.

Autodesk.AutoCAD.Internal.Utils.SelectObject(New ObjectId() {})

So in summary,  you must get an array of ObjectId's and pass to the SelectObject method.

I add Object to listview include Object ID 

I am try to DoubleClick in listview to select Object I select in Listview

Thanks will check out Editor.SetImpliedSelection

           For Each colId In colIds

                Using trans As Transaction = Autodesk.AutoCAD.ApplicationServices.Application.DocumentManager.MdiActiveDocument.TransactionManager.StartTransaction()

                    dbObj = trans.GetObject(colId, OpenMode.ForRead)
                    ObjectIDsave = colId.ToString()

                    If TypeOf (dbObj) Is BlockReference Then

                    Else
                        Dim l As Polyline = DirectCast(dbObj, Polyline)
                        stLength = stLength + l.Length.ToString
                    End If
                    trans.Commit()
                    trans.Dispose()
                End Using



            Next colId

' Add to listview !
