I use

AppDomain.CurrentDomain.UnhandledException += new UnhandledExceptionEventHandler(CurrentDomain_UnhandledException);

in Main() method

but in SC-BAT Feb 2006 used:

Application.ThreadException += new ThreadExceptionEventHandler(ApplicationThreadException);

for catch exceptions from UI thread

I try write simple application with use CAB.

// In MainForm class i have method that fire by click button on the form
// In this method i throw exception

private void button1_Click(object sender, EventArgs e)
throw new InvalidOperationException("Oops");

// CabeeApplication
public class CabeeApplication : FormShellApplication<WorkItem, MainForm>
static void Main()
// If this line not present OnUnhandledException never fires!
// I try without Debugger attached!
new CabeeApplication().Run();

public override void OnUnhandledException(object sender, UnhandledExceptionEventArgs e)
MessageBox.Show("Unhadled Exception!!!");

I have experienced the same problem and this thread helped me resolve it, thanks.

My application is built on the SC-BAT March drop, but it still had the symptoms more or less as described. Running under the debugger everything worked fine, but outside the debugger, the UI thread exceptions were not caught.

These are the changes I made, prompted by this thread:

static void Main() {
//Commented out:
//AppDomain.CurrentDomain.UnhandledException += new UnhandledExceptionEventHandler(AppDomainUnhandledException);
//(AppDomainUnhandledException never gets called)
// Added:


try {
new ShellApplication().Run();
} catch (System.Exception ex) {

This works, but the original SC-BAT approach did not work, as the assigned handler (AppDomainUnhandledException) never got called.

Any comments from the SC_BAT team are welcome.
