ID: Q164137

The information in this article applies to:

Visual Basic 5.0 Order Processing Pipeline (OPP) components are not supported for Microsoft Commerce Server version 2.0.

Visual Basic 5.0 COM components are implemented using an apartment threading model that is not supported by Commerce Server. apartment threaded components in the OPP would become processing bottlenecks. Therefore, it is recommended that OPP components be free threaded (marked as "both" in the registry).

The following is a list of fully supported alternatives to using OPP components:

    - Java

    - C++ (MFC/ATL)

    - VBScript

    - JScript
