Do you have Outlook available? If so it's pretty easy. Are you figuring on attaching the file or incorporating it into the body of the e-mail?
I've got Outlook 2002 and there's a help file named VBAOL10.chm. Different versions of Outlook will have different names. Just search for VBAOL*. This help file will show the details on how to automate Outlook. Bear in mind that it's written for VBA so there will have to be a little syntax translation to make it work in VFP. If you want samples, just ask.
Outlook express, unfortunately, can't be automated, so you'll have to go another route. I believe there's also a strictly VFP mail .dll, but I haven't used it, so I'll leave it to someone else to explain.
