Juval Lowy provides the BackgroundWorker component to facilitate easy asynchronous invocation with Windows Forms in Net 1.1, but when an exception occurs in BackgroundWorker(DoWork event) - it behaves as though happened nothing.It is possible to understand what happened just by analyzing Error

private void backgroundWorker1_DoWork(object sender, DoWorkEventArgs e)

{

 throw new ApplicationException("exception");

}

private void backgroundWorker1_RunWorkerCompleted(object sender, RunWorkerCompletedEventArgs e)

{

 string message = string.Empty;

 if( e.Cancelled )

 {

   message = "Cancelled";

 }

 else

 {

  if(e.Error !=null)

  { // analyze error here

    message = "Error";

  }

  else

  {

    message = "Stoped";

  }

 }

 MessageBox.Show(message);

}
