I have a WPF application that spins off several threads. I have defined a DispatcherUnhandledException event handler in App.xaml.cs that displays a detailed error message, and this handler gets called every time the UI thread encounters an exception. The problem is with the child threads: their unhandled exceptions never get handled. How do I do this?
Sample code:
private void Application_DispatcherUnhandledException(object sender, System.Windows.Threading.DispatcherUnhandledExceptionEventArgs e)
{
MessageBox.Show("detailed error message");
}
private void Application_Startup(object sender, StartupEventArgs e)
{
//...
//If an Exception is thrown here, it is handled
//...
Thread[] threads = new Thread[numThreads];
for(int i = 0; i < numThreads; i++)
{
threads[i] = new Thread(doWork);
threads[i].Start();
}
}
private void doWork()
{
//...
//Exception thrown here and is NOT handled
//...
}
Edit: Once an unhandled exception occurs, I want to display an error message with a stack trace, and then exit the application.
