This article ask to give reference to COMSVCSLib.AppServer in VS 2005, This can be done by add reference - COM tab - select COM + Service type library and add its reference. Then change this
Dim ctx As ObjectContext
Set ctx = GetObjectContext
Dim ctx As COMSVCSLib.ObjectContext
Dim objAppServer As New COMSVCSLib.AppServer
ctx = objAppServer.GetObjectContext()
It should resolve the issue.
