How to creat a stop button to stop the process in VC++

[friendjin]

Thanks in advance;

Can I ask a question about VC++.NET 2003.
about using window form application.
when I click button1, the programming will be run, and the
results will be displayed in textbox1, we are able to see update values in
textbox1, to achieve this function, I used the while loop to loop forever.
you know the problem is it could not be stopped.
So I want to create a stop button, once I click this button, it should be
stopped immediately, but not exist the form.
e.g

private: System::Void button1_Click(System::Object *  sender, System::EventArgs *  e)
{
while(true)]
{
}
}
private: System::Void button2_Click(System::Object *  sender, System::EventArgs *  e)
{
}
 

But I have no idea how to write the code for stopping.
can anybody give me some idea?

someone told me I could use thread.. as once clicking the start button, the proccess will keep running, at the same time, it is impossible to click the stop button. have to using some way to start another process during the previous process running.

but i have no idea how thread works. anyone can give me some idea. thanks.
