Powershell controlling MSWord: How to select the entire content and update? - powershell

Question

I am dealing with a whole load of Word documents that make heavy use of fields and cross-references (internally and between documents).
To update these and make everything consistent again after a change I have to open each file, select the entire file's content (equivalent of hitting Ctrl-A) and update all fields (the equivalent of hitting F9). And I have to do this twice for all files, so that also all inter-file cross-references are also updated properly.
Since this is a rather tedious and lengthy process I wanted to write me a little PowerShell-script that does that for me. The relevant function to update a file looks like this:
...
function UpdateDoc([object]$word, [object]$fileHandle) {
Write-Host("Updating: '" + $fileHandle.Name + "' ('" + $fileHandle.FullName + "'):")
# open the document:
$doc = $word.Documents.Open($fileHandle.FullName)
# select the entire document:
???
# update it:
???
# then save it:
$doc.Save
$doc.Close
Write-Host("'" + $fileHandle.Name + "' updated.")
}
...
But I am stuck on how to select the file's content and update it all, i.e. what has to go into this code instead of the two ???-markers to achieve what I want?

Answer 1

Did you try:
$doc.Fields | %{$_.Update()}
That should update all the fields
