I have added a worker thread to a form, in my class I’ve added:

static bool msblnRunPinger = false;
const int mcintPingerSleep = 100;
Thread mthrdPinger = null;

In my class constructor:

if (mthrdPinger == null) {
   msblnRunPinger = true;
   mthrdPinger = new Thread(new ThreatStart(pingSites));
   mthrdPinger.Start();
}

When the form is closing:

msblnRunPinger = false;

The thread function:

private static void pingSites() {
    while(msblnRunPinger == true) {
//Problem is here...How can I access the form controls in a static function?

        Thread.Sleep(mcintPingSleep);
    }
}

See above, I need to access the form controls in the thread body, how can I do this?
