Filter Development Process

The filter development process is described in general terms. In describing this process, use of the Visual Studio® Active Template Library (ATL) is assumed and recommended because it handles routine work for the project.

Application filters typically require these procedures:

• Create the necessary COM objects. Typically, these are the filter object, session filter object, and data filter object.
• Monitor events.
• Attach the filter to a session.
• Process data.
• Provide code to register and unregister the filter.
• Install the filter.

Note  Filters must be registered as COM servers and in the Forefront TMG configuration.
