I am having an issue with a vbscript set to run as a Data Validation script triggered by an OnAfterChange event.

The Error I get is An error occurred in the form's code. The number of calls to the OnAfterChange event for a single update in the data exceeded the maximum limit.

I have found a few articals on this error but all of them pointed to jscript which I am unfamiliar with.


Sub msoxd_my_txtServerName_OnAfterChange(eventObj)

' Write code here to restore the global state.

If eventObj.IsUndoRedo Then
' An undo or redo operation has occurred and the DOM is read-only.
Exit Sub
End If

' A field change has occurred and the DOM is writable. Write code here to respond to the changes.
Dim objServerName
Set objServerName = XDocument.DOM.selectSingleNode("//my:myFields/my:txtServerName")
objServerName.text = ucase(objServerName.text)
End Sub


Any help would be much apperciated... Thanks!

This code is causing an infinite loop. When you use "objServerName.text = ucase(objServerName.text)" it calls the OnAfterChange event of that node (which is itself) and causes recursion.

Greg Collins has written a HowTo on this issue, it can be found here:

You will use a boolean variable to indicate whether it is the code changing the value of the field or the user.

Thanks for the pointer, I had read this artical prevously but Unfortunitly all of greg's examples are in jscript and I am working in vbscript and am having troubles adapting the concepts between the two
