.NET CF 2.0 COM/COM+ Access

[Seraphin]

Currently, I am trying to implement a COM into CF 2.0 I've already implemented and registered the DLL successfully. But I always get a "NotSupportedException": Type objType = Type.GetTypeFromProgID("MacroCOM.dll); object oAct = Activator.CreateInstance(oType); object[] parameter = new object[1]; parameter[0] = 5; //long objType.InvokeMember("MCOMConnector",BindingFlags.SetProperty, null, oAct, parameter); //this lines executes the error Any solutions there? TIA.
