Detecting network connection for your AIR application

Geplaatst op 7 februari 2008 door Gerdt Brouwer

I was looking at the internet for the simple solution to see if my air app has connection with the internet.

I found a lot of blogs, all telling me a little more, but no direct good demo.
This is the source I use while I work with AIR beta 3.
