My Windows form has two buttons: "Start" and "Stop". How can I stop the form
from doing whatever it is doing without closing the whole application? The
"Stop" button would have to stop a process that's being run in another
class, not from within the form.
Thanks.

Hi,
It depends on the process being run.
I suggest you to run the process within a worker thread and use some sort of
synchronization mechanism to inform the process that it should stop
(ManualResetEve nt perhaps).
Or, if you are careful enough you might use Thread.Abort (not recommended).

Do you mean an actual other process, or just another thread?
Have a look at http://www.pobox.com/~skeet/csharp/m...worker.threads
for code to shut down a worker thread gracefully.

It's just another process. I'm not using threads.

How do I know which process I need to kill? How would I know what process ID
was generated when I started the process?
Thanks.

You'd keep hold of the Process reference from when you started it.

I'm still not sure I understand. In the MSDN, the example shown is for
starting a process by running an application outside of the project. How can
I get the Process reference when I call the method that'll be executed?
Thanks again.

Which example are you talking about?
The static Process.Start methods return a Process reference - that's
the thing to keep hold of so you can call Process.Kill/CloseMainWindow
on it later.

From what I've seen in the web and MSDN, Process.Start() is used to run an
external application (ie. Process.Start(" notepad.exe", "myfile.txt ") ). In
my Windows app, I'm trying to stop a method that's being executed in another
class:
private void btn_start_Click (object sender, System.EventArg s e)
{
ZMMatch.Output myOutput = new ZMMatch.Output( );
myOutput.writeO utputFile();
}
private void btn_stop_Click( object sender, System.EventArg s e)
{
/* Here I want to stop myOutput.writeO utputFile() from running */
}
Thanks.
