Michel, check out the example in ASPvote. It is basically running a JS routine to run a VFP mtdll in the background. With this concept, you can have any kind of interactivity on any static HTML or dynamic .WC page, etc. The key for it is the JavaScript.
>With WWC or any other approaches, is there a way to return only a javascript message to the browser in order to have the calling page to remain as is on the browser without having to return any HTML at all except that javascript message?
