Cool! Waiting to see how it's done...
(Hmmm.... May be I should try to run VFP on my Rocket eBook... :)

>OK, I'll brag a little. It was pretty tough. As you know, the memory footprint of VFP ain't exactly svelte, and Palms have anywhere from 1 MB (the original Palm Pilots) to 8 MB (Palm Vx). So I had to figure out how to shoehorn the whole thing into Palm RAM while leaving enough space for, er, um, what was that, what did I need? Oh, yeah. Data! Unfortunately, you're not going to be doing VFP SQL SELECTS on 2 million row tables on your Palm.

I didn't think so), and hooks to the native data engine as well as ODBC (when ADO actually works, I'll throw that in too *g*). I've also added a hook to the Graffiti engine to recognize common VFP objects, so that will make Palm development a lot faster.

>Anyways, seriously, I have a VFP app running on my desktop that automatically grabs data from my handheld during a HotSync, and then downloads new data entered into the PC back to the handheld during the same Sync session. Right now it's proof of concept, but it _does_ work, and I'll be popping details as I get them sorted out and organized for presentation up here - probably within a week or so.
