I've just tried building an AIR application out of an html file, which communicates to a MySQL database using AJAX with a post request on a php file.
In the browser, the 'real' webapp works as intended, but when I build an AIR application, nothing happens when clicking on the send button.
Does AIR not support this? Or am I missing something else here?
You probably need to post a little bit more info on what your program do before people can help you.
