Bill,
There's an article on my website showing all the named items that the MS mailto: target support. You should be able to find the some documentation on the Groupwise version from them.
>lcMailTo = "mailto:" + ALLT(lcRecipient) + IIF(NOT EMPTY(lcSubject), "?subject=" + lcSubject, "")
>
>This works fine for Outlook or Outlook Express. However when we try to do this on a machine that is using GroupWise as their e-mail client (which has a FROM field as well as a TO field), the mailto address winds up in the FROM: field, and the subject winds up in the TO: field. I've been handed the responsibility of correcting this problem, but I'm not even close to a Win32API expert.

>Is there any way that I can force the mailto: address into the TO field, regardless of wheter I am using Outlook or GroupWise (or Lotus Notes, for that matter), or pass an optional from: field that will be ignored if the e-mail client (Outlook) does not make use of it? If not, is there an easy way (i.e., redesigning the e-mail utility with WestWind's tools are not an option) that I can detect what my e-mail client is, and then create my lcMailTo variable accordingly?
