In class we talked about the ability to handle errors in our scripts. The question came up as to how many potential error codes there are. Run the script below to find out. Remember that the function your are attempting to provide error handling for will not be capable of generating all these errors. You only need to script against the most likely ones, and then a catch all for anything unusual that pops up. This script uses a method that we did not talk about in class, Err.Raise. You use Err.Raise followed by the error number that you are interested in to help you test your error handling. This will cause your script to believe that the error actually occurred and invoke your error handling.
Dim errDef, i
WScript.Echo "Number", "Description"
On Error Resume Next
errDef = Err.Description
For i=1 to 2^16-1
If Err.Description <> errDef Then
WScript.Echo Left(Err.Number & ":" & Space(6), 6), Err.Description
