Visual Basic .Net - list of all values of runtime errors ("Err.Number" and "Err.Description")

If you could tell us the reason  behind compiling this list, we may be able to help you better.
In the same link above, there is a sub link to run time error messages. Which is the link below:

Hi Karrtik,

Thanks so far.

When users of my application encounter an error, they can click a button that takes them to a webpage with general information.
The value of "Err.Number" is emailed to us, but not "Err.Description".

Right now I'm particularly interested in "Err.Number" = 408 - can you tell us what "Err.Description" is for that error?

Regards,
Leigh

Hi Leigh ,

At a very high level (at say 10000Ft level), can you explain the scenario when this error occurs which an outsider like me can understand without getting into internals?
Also can you share if your application is web APP or a windows APP?
Meanwhile I am looking at what could cause 408 errors.
Normally 408 error could mean that a request sent to remote server timed out.
Thanks,
Karrtik

Thanks to Karrtik Iyer and Ark for your suggestions.

It turned out that the error was from a Intel Fortran app.  
Sorry that I thought it was from VB.
