Force app to crash and not show dialog box?

Is there a way to configure windows 2016 to not show this dialog box and silently crash so another app can restart it automatically?

If not open to other suggestions
Its a legacy app we have code for if we need to edit we can.

Sure. When an Exception happens anywhere in your application, that Exception is generally passed to an Exception Handler. It bubbles up the stack until it finds a registered handler. If it can't find a handler, then your program crashes with the above Unhandled Exception error message. Basically, it's saying that your app threw an exeption (had a problem) but there was nothing in play to catch and handle it.

Generally speaking, when writing an app, you will always have an Unhandled Exception handler of some sort. The whole purpose of that is to prevent the above error message. By the time your code reaches that handler, there's nothing you can really do to stop your app from closing, but you can at least handle it in a more meaningful way (friendly message to the user / info written to a log file / database connection closed etc.)

How you hook up an Unhandled Exception handler will depend on the dev tools you're using ( WPF / Winforms etc).

There isn't a way to prevent the message coming up other than fixing it or 'handling he exception.'
You could run in in a different session to prevent it displaying on your screen but that wouldn't stop it appearing as such as it would just appear on a different desktop session.

It may be possible to deal with the error when shown though. Many automation tools can monitor for that window and take a pre-planned action (clicking OK) to get rid of it.

if this is worth a go, try tools like Think Automation or Autohotkey etc.

Thanks all
The generic unhandled exception handler sounds OK, would that be on main, and what would the catch bit look like?
