application.set???

This will set an application scope variable, available to all instances of your application. That is the value is shared between all users of your app. One thing to keep in mind is the situation where more than one user changes the value simultaneously. You can do this

application.lock()

' set your application variable

application.unlock()

' carry on

This will serialize all attempts to change this variable.

Hope this helps.
