Calling Webservice Method from a timer method

[FaisalJ]

I have created a timer.

TimerCallback timerDelegate = new TimerCallback(MyCallBack);

Timer timer = new Timer(timerDelegate,num,1000, 1000);

Simply call MyCallBack function after every second

Now in MyCallBack I just call the HelloWorld function of a simple webservice and displays that value in a listbox

void Inform(Object state)
{
m_lb.Items.Add(s.HelloWorld());

}

The funny thing is that this works only 19 times ...the string Hello is displayed only 19 times after which is stops....


WHY????????????
