asynchronous

Hi,
I have read that I can use asynchronous call with polling especially when the caller thread serves the GUI. I cannot see how because:

while(AsyncResult_.IsCompleted==false) //this stops the GUI thread
{
}

So how it come it should be good for this purpose? I needed to update my GUI status bar everytime deamon thread did some progress..
