You have to say "please".
Seriously, we're not out to be rude, but we'd rather not have the forums read like SMS L33TSPK. Unlike Arabic, English isn't a vowels-are-optional language. Think of it as I18N. Which, some to think of it, is a pretty L33TSPK term itself.
Anyway, what you're looking for isn't actually a "CTRL-C", it's what the program encounters when you type CTRL-C. Under unix, this is a SIGKILL and under Windows, it's what you'd get by calling TerminateProcess (or so the java.lang.Runtime JavaDocs tell me).
I'm unclear when and how you want to fire this interrupt. In Eclipse/unix, one way to do it is to use the "Run/External Tools" menu option and invoke the Unix "kill" program.
At a lower level, you could write a JNI class that invokes the kill() system function - or for windows, invokes TerminateProcess. The hard part is getting the process ID for the JVM you want to kill. And, of course, unless the app's running in a different JVM than Eclipse itself is, killing the JVM kills Eclipse as well.
Note that Sun explicitly states that ctrl-C-type interrupts may terminate the JVM
without invoking the shutdown hook, however! So invoking exit() isn't such a bad idea after all.
