Create a COM Object that Implements the IFWXDataFilter Interface

When you create the data filter object, you will implement the following methods:

• IFWXDataFilter::SetSockets
• IFWXDataFilter::Detach

Warning  Visual C++ will not create a new ATL object if more than one .idl file is included in your project. Delete all the .idl files except SMTPFLTR.idl from the project, add the ATL object as described, and then replace the .idl files that you removed.

1. Follow cleanup steps similar to those taken to create the COM object that implemented IFWXSessionFilter. This includes the copying and restoration of files, removal of specific files, and removal of several lines of code. See the topic Create an IFWXSessionFilter COM Object to review the cleanup procedures.
2. Insert a new ATL object (Object — Simple Object)
