Hi Martin....

The site Susan mentions is worth a look but it covers just the basics. While I've not found a lot of online "courses" there is a lot of online learning material out there with some free stuff and some that costs. You might check out some or all of the following....

www.microendeavors.com
www.keystonelearning.com
www.takenote.com

www.pinpub.com/foxtalk/home.htm (articles and enewsletters)
www.advisor.com (home of Foxpro Advisor among others... some articles and a tips enewsletter)

www.westwind.com (white papers and tech articles)
www.lespitner.com (tech articles...lessons)
www.stonefield.com (articles... some by Doug Henning that are really good)
www.stevenblack.com

Jim Booth, who frequents this site, has a web site with great stuff on it but I can't seem to find where I put his site url.

The Virtual Foxpro Users Group at www.vfug.org has lessons and newsletters. Some of the heavy hitters here at the UT (and one moron < s >) write articles for this publication.

The fox wiki has tons of stuff.... http://fox.wiki.com (I think ?)

Anyway... I hope this helps!
