Yes, I know that. I mean what the number means? where I can find a list
of all numbers?

For exmaple, the Workbook.Open method could throw exception when you try to
open a workbook that already opened. Excel display to use a message say "Do
you want to update.....". and if the user click No, Open method throw
exception with number. and I interested to see all possible error that the
open method could throw?
