im a visual foxpro programmer but i have a problem using avfp converting my desktop app to the web, and i really dont know where to start, the installation have no problem but i don't know how to start with the object like textbox, combobox etc. returning its value. I don't have knowledge in asp. and I really want to learn this avfp. if someone can help me the basics how to return the textbox values even in messagebox() is a really great help. I purchased westwind connection and I really like their video tutorial because its well explained, but i have a problem running it on my virtual private server (godaddy). if someone can help will really be appreciated. Thanks and more power.

All your desktop form object (such as textbox, combobox, button, etc..), in AVFP are HTML object. If you have a form with one button and one textbox, in AVFP you need a code like this:
<input type="text" name="txtobj" />
<input type="button" name"btobj" />
If you need to send data, you need to use a form request, like this:
<form name="f1" method="post" action="yourpage"+oProp.Ext>
    <input type="text" name="txtobj" value="" />
    <input type="submit" name"btobj" value="Send" />
</form>
Note that the button changes the type, with "submit" can be send data. For getting the data, in "yourpage.avfp" you need to use oRequest.Form("txtobj") to get the value of textbox.

If you read the "Documentation" and see the "Examples", you'll find all that you need.

Shef, programming a web app if fundamentally very different from programming a desktop app. All the knowledge you have right now about creating UI/UX en VFP worth exactly NOTHING to build a web app. You need to start by grasping a basic knowledge of the technologies involved in web programming:

1) HTML
2) CSS
3) JavaScript
4) JSON
5) Ajax
6) REST services

All of this will be required no matter what language you use for the server side code (PHP, AVFP, .NET, Python, etc). Only after you have a basic understanding of how a web page works and the interaction between the browser (browser side code) and the web server (server side code), you could understand the role AVFP plays on allowing you to use VFP code to feed your web app.

Traducir del: Español

analyze the code an try to understand the way it works.
I wonder if I could count on your help when I need it, and if you understand the Spanish language would be great.
I would be more confidence.

thanks in advance
