VBScript Error Logging problem when using Err.Raise

[Jimbobjeff85]

Sorry about the fact this is probably quite a basic question!

I'm playing around with error logging in VBScript and I can't get it to log an error after I use err.raise to create one. If I comment out the Err.Raise it writes to the logfile with no error information. If I comment out the 'On Error Resume Next' but leave the Err.Raise uncommented an error is generated.

I am using VBS Edit to write the script.

Script is:
-------------------------------------
Option Explicit
On Error Resume Next

Dim objWshShl, objFsoObject, objLogFile
Set objWshShl = WScript.CreateObject("WScript.Shell")
Set objFsoObject = WScript.CreateObject("Scripting.FileSystemObject")

'Main Processing Section

Subroutine()
WScript.Quit()

'Procedure Section

Function Subroutine()
Err.Raise(6)
If (objFsoObject.FileExists("C:\ErrorLog.txt")) Then
Set objLogFile = objFsoObject.OpenTextFile("C:\ErrorLog.txt", 8)
Else
Set objLogFile = objFsoObject.OpenTextFile("C:\ErrorLog.txt", 2, True)
End If

objLogFile.WriteLine "Test.vbs Error: " & Err.Number & ", Description = " & Err.Description & " , Source = " & Err.Source
objLogFile.Close
Err.Clear
End Function
----------------------------

Any ideas? I'm sure it's something basic I'm doing wrong.

I'm not sure if I can explain this clearly but it is acting exactly as expected.

You are calling Subroutine which has an error in it. Since Subroutine doesn't have error handling in it the error immeditaly bubbles up to the calling procedure without allowing the procedure to complete. Since the calling procedure has error handling it complete without barking about it.

Try placing On Error Resume Next inside Subroutine before calling Err.Raise and see it that does it for you.

Hi MarkT, thanks for the reply.

Yep - moving the On Error Resume Next to within the subroutine worked - many thanks!
