Carlos,

>Hi; I have VFP7 and Windows XP; I need to make my data available in the web, and I found FOXISAPI; I followed all the instructions and samples I could find; but I could only make wotk the Hello sample; when I try to get data, I allways get an error. Have anyone tried to use Foxisapi?

In addition to Don's post you can also use Active Server Pages or ASP.Net to host VFP COM components which is probably the most 'official' free mechanism that Microsoft has for VFP integration with the Web. This route is free but also like FoxISAPI requires a lot of hunt and peck for debugging...

You might want to take a look at:

There are a number of articles there that talk about using Visual FoxPro and IIS together including very detailed articles on FoxISAPI, ASP and COM and ASP.Net and COM.

Hope this helps,
