Actually, I'd have thought it would be more useful to ensure the TOC updates upon opening, as that ensures the refernces match any repagination, etc due to printer changes and the like. Adding the following macro to the Normal Template's 'ThisDocument' module will update all fields in every document that gets opened:
Code:
Private Sub Document_Open()
Application.ScreenUpdating = False
Dim TOC As TableOfContents ' Table of Contents Object
Dim TOA As TableOfAuthorities ' Table of Authorities Object
Dim TOF As TableOfFigures ' Table of Figures Object
Dim Rng As Range ' Word Range Object
With ActiveDocument
' Update fields in each Story.
' Note that this may trigger the updating of ASK & FILLIN fields
For Each Rng In .StoryRanges
.Fields.Update
Next
' The following routines are necessary because the foregoing updates only page numbers
' in TOCs, TOAs and TOFs - field updating doesn't update TOC, TOA or TOF contents.
' Loop through Tables Of Contents and update
For Each TOC In .TablesOfContents
TOC.Update
Next
' Loop through Tables Of Authorities and update
For Each TOA In .TablesOfAuthorities
TOA.Update
Next
' Loop through Tables Of Figures and update
For Each TOF In .TablesOfFigures
TOF.Update
Next
End With
Application.ScreenUpdating = True
End Sub
Note: Venky's code will throw an error if the document doesn't have a Table Of Contents.
