Appeon - Which target to include emailing of an attachment?

Greetings All,

I am converting an application to Appeon.  All is working out rather nicely.

I am at the point where I need to provide the user with the ability to export (SaveAs) a datawindow as an Excel file and email.

Usually, I do that with Webform where I add system.net and then add helper.dll which I got from someone at Sybase a long time ago.

I added system.dll, but I cannot add helper.dll like I normally do in the Library Painter.

My current target is an 'Application' using PB 12.5.1 and Appeon 2013 R2 Build 0126.00.

Any pointers will be appreciated.

Thanks!!

Paul
