I have an application that has two different login windows for two different types of users of application, say one is client and the other is administrator , now i want to have an option on both the Login windows to set the default opening window, something like a checkbox having label as set this is as your default Login window ..

How can i achieve this??

May i use a
Java Code:
.properties
file to set the default window? (and How?)

Or, a
Java Code:
Main.java
class which loads first and decides the default GUI window to load first??

I preferred the 2nd way...but your views are welcomed, also please provide some example codes to accomplish this task.

Regards,

Asif
