Hello all,  
A client asked if it’s possible to reboot the system using a button from flash after the viewer has watched the flash presentation?

From Visual Basic, executing the command “Environment.Exit(-4)” will shutdown and restart the program. This actually exits the control program and the watchdog program that is running in the background then restarts the main program. The -4 is not particularly important, but it is currently designed to look for an exit code with a negative value.

Is this possible to execute the “Environment.Exit(-4)” command using AS3?

Any help is much appreciated. Thanks!
