Check if thread is waiting for input or frozen

[=?Utf-8?B?R2lkaQ==?=]

Hi,

Is it possible to have thread that will check if another thread is waiting
for User input or frozen?

thanks,
Gidi.

Hi,
Check thread's isAlive and ThreadState properties that may help you.

Thanks,

Define "frozen". That's not a standard technical term in Windows
programming and could mean any variety of things.

That said, it should not be necessary for you to do this. You will
probably get better advice if you explain why it is you think you want to
do this and what you hope to accomplish.

Generally, I think he means "not responding". I agree, however, that's
not very clear. Does it mean not receiving user input, or not using
any
CPU time or...

I would imagine he's looking for a heartbeat sort of mechanism to see
whether a program has "died" and needs to be restarted. Having written
more than my share, it sounds like the description given.

The phrase "not responding" isn't very clear either. What does
"responding " mean? For a thread with a message pump, this often (though
not necessarily) means that the thread is pumping messages. But most
threads don't have a message pump. And many types of threads can sit and
process for long periods of time without ever interacting with any other
thread. Are those threads "not responding", even though they are working
exactly as designed?

Well, only Gidi can elaborate. Thus my question. We can speculate until
the cows come home, without a more descriptive question I don't see any
way to offer practical advice.
