Hi,

This is my Program class in my Application -

   static class Program
   {
       /// <summary>
       /// The main entry point for the application.
       /// </summary>
       [STAThread]
       static void Main()
       {
           Application.EnableVisualStyles();
           Application.SetCompatibleTextRenderingDefault(false);

           // Subscribe to thread (unhandled) exception events
           ThreadExceptionHandler handler = new
ThreadExceptionHandler();
           Application.ThreadException += new
ThreadExceptionEventHandler(handler.ApplicationThreadException);

           Application.Run(new FormMain());
       }

       /// <summary>
       /// Handles any thread exceptions
       /// </summary>
       public class ThreadExceptionHandler
       {
           // set when there is an unhandled exception. Can therefore
be used by FormMain.
           static bool unhandeledException = false;
           public static bool UnhandeledException { get { return
unhandeledException; } }

           public void ApplicationThreadException(object sender,
ThreadExceptionEventArgs e)
           {
               try
               {
                   unhandeledException = true;
                   ShowThreadExceptionDialog(e.Exception);
               }
               finally
               {
                   // Fatal error, terminate program
                   Application.Exit();
               }
           }

           /// <summary>
           /// Creates and displays the error message.
           /// </summary>
           private void ShowThreadExceptionDialog(Exception ex)
           {

from with FormMain I do the following if there is an exception which
is to not save the users settings -

       private void OnClosing(object sender, EventArgs ev)
       {
           if (Program.ThreadExceptionHandler.UnhandeledException)
               return;

          // save user settings...
      }

The problem though is that if I create a thread as follows, exceptions
are not being handled by ThreadExceptionHandler  -

public void FormMain_Load(object sender, EventArgs e)
       {
           thread = new System.Threading.Thread(MyThread);

           thread.Start();
       }

       void MyThread()
       {
           throw new ApplicationException("My exception");
       }

Why not?

Thanks as ever,

Aine
