ActiveX components are a distribution mechanism for COM+ class behavior operating behind COM+ interfaces in the context of dynamically constructed COM+ objects. That means the behavior of MSMQ ActiveX components is well encapsulated, and the wayit was developed has nothing to do with the way it is used. In Visual C++ alone, there are several ways to make use of the MSMQ components, including raw COM+ interfaces, Class Wizard dispatch wrappers, and ATL-style smart pointers. A multitude of additional techniques is available in other languages. For example, you'll try three different approaches: raw COM, smart pointers with ATL, and finally a Visual Basic script to ensure low-level programmer humility.
