ugly exception messages

[Jon Paal]

how can I get a better looking exception error message to display, instead of the standard error page from asp.net when throwing an
exception like:

If allowExceptions And license Is Nothing Then
If errorMessage Is Nothing Then
Throw New LicenseException(type)
Else
Throw New LicenseException(type, instance, errorMessage)
End If
End If

You can use custom error pages, or catch errors at page elevel (Page_Error
or event handlers) and show it in a nice Label or something.

The trick I found to work is to use Synchronous HTTP Handlers

In your Global.asax you can handle the Application_Error event. From there
you can do what you like with the exception. You can access that exception
as...

Server.GetLastError

Based on what went wrong you may be able to handle it. Otherwise you can
simply call Response.Redirect to send the user to a static error page.

You can also log the exceptions at this point, perhaps placing it in a
database, and run metrics on it to determine the most frequently raised
exceptions to prioritize which ones you fix first.
