air process adt flex

Question

I have two air applications and installed them in desktop and executed them and two air processes are listed in taskbar manager.Now how can I execute some method of one air application from another air application?

Answer 1

Use LocalConnection.

You can Host a Connection in one AIR application and connect from the the other AIR guy... From there - you can call methods.

BEWARE: LocalConnection can be a little tricky and odd (for example, connections are global and the names can't overlap).

From the Example Doc listed above....
