Am I correct in understanding that despite all the advances AIR & Flex Builder bring to the table, that I can no longer launch an external application like I could back in Flash projectors (e.g. fscommand(“exec”,appName))??

Looking for a way to launch a site in Firefox since it isn’t compatible with the webkit browser built into the HTML object of Flex Builder 3.

The AIR app needed to display a 3rd party site which had rendering issues under the Webkit (AIR) browser. As the site worked fine in IE & Firefox, we had to launch that browser instead. I used navigateToURL for now but was just confirming the flash player is sandboxed in a way unlike the old “fscommand(“exec”,“someApp.exe”)” option within Flash projectors.

So you’re confirming that there’s no way to go beyond this to (for example) have an AIR app with 5 buttons, each of which could open a (non-browser) app such as an on-screen keyboard, etc.?

[QUOTE=magcius;2320232]I’m confused. What is the site built in? If you want to launch an online site, like a URL, you will need to use “navigateToURL”

Otherwise, Flash Player is built into the browser and cannot launch external applications, as this would be a serious security threat. (download and launch installCreditCardStealer.exe)

What “application” (or site) do you need to launch?[/QUOTE]
