>Would you mind giving me some further hints as to what you mean by, "writing your own code in VFP to update the DHTML for XP themes would be a fair amount of work." I'm not afraid of work that I can do <g>. I'm just not sure what you are suggesting.
You can access the IE DOM (document object model) with VFP code and modify the HTML/DHTML. Refer to the whitepaper on this topic at west-wind.com. I don't think adding XP themes dynamically like this will be easy, probably a major task.
