Question

I’m starting a Thread that runs routine tasks with some Files, unfortunately, calling Thread.Sleep inside that thread callback hangs up Windows for the specified time, ie. my cursor freezes and CTRL+ALT+DEL does nothing either. How do I specifically “Sleep” the background thread without hanging up the UI?

I’m creating the thread using this:

 createThread = new Thread(new ThreadStart(this.createFileExec));
 createThread.Start();

And my callback is like this:

    private void createFileExec() {
        ....
        Thread.Sleep(100);
        ....
    }

That’s exactly what you are doing by calling Thread.Sleep on your new thread. Are you sure you aren’t calling createFileExec from the main thread?
