Hi George,

Thanks for the response. I don't have a problem returning the error message from the .dll. My problem is that it is a fatal error (Zip Code Not Found) or similar. This may be an error I inserted delibrately to test if the .dll would catch it and what message will be displayed. Problem is that I test several 'fatal' errors and I don't want the (I send 15 addresses some with delibrate errors) test program to continue to/thru the last test address.

But the .dll considers this a fatal error and crashes. Suggestions?

Regards,

Paige
