I’ve designed a website that works through my own PC.
I set the IIS to work with Custom Errors in case user ran into some unknown exception.
I’ve also added a check that the error page will e-mail me whenever it found an error.
Can I somehow get the error information (Stack and description) from the error page?
I encourages you to use Open Source library out there that provided functional need. My recommendation is ELMAH.
With a few line of settings in your web.config, you will all set. result screen looks like this.
