>We have used ICVerify for many years. At startup, user loads ICV multiuser program which periodically watches for a request file (CSV). When an authorization is required, application creates a request file (CSV) containing one or more transactions then waits for an answer file (also CSV). In the meantime the ICV multiuser program processes the request file, creates the answer file then goes back to sleep. Our program then processes the anser file. Has worked great. ICV offers dialup or net access to card processors depending upon each processors capabilities. Regards.

The documentation mentions an ActiveX control. Have you used that?
