Enable button clicking while another process is running

Question

I look trough google a bit but cant make it work.

I have some process done when i push a button.

I want to add a "Kill All" button to terrminate everying when pushed, but when i start a process i cant push any other button untill its finnished.

private void button_checkZero_phones_Click(object sender, EventArgs e)
    {
        Thread thread = new Thread(new ThreadStart(WorkThreadFunction));
        thread.Start();
    }

private void button_kill_all_Click(object sender, EventArgs e)
    {
        System.Environment.Exit(1);
    }

sounds like you're doing the processing on the UI thread which will lock the application until the process finishes. The only way to keep the UI responsive is to do the processing on another thread — NDJ, Aug 28 '13 at 09:45
Could you post your code to show how you start your processes? — King King, Aug 28 '13 at 09:48

You have to run your "Kill All" method in an async method. The main thread is always blocked when you run a long process.

More info about your problem: WinForm Application UI Hangs during Long-Running Operation

Just use one of the following methods - run Kill All in:

A BackgroundWorker
Another thread
Another task
Use async/await
Reactive extensions

There are a several ways to notify you that the all processes are terminated! It depends on which method you use.

Is this a Windows app? If you're feeling old-school and enjoy winding up other developers, stick an Application.DoEvents() in your loop of death.

You know you want to.

Of if you want to do it without receiving scorn from all your peers, see this question and answer.
