better method for accenting every word in Word document? - vb.net

Question

I am new to programming, but I am trying to adapt an existing script as a MS Word 2010/2013 addin to add correct stress accentuation to every Latin word in an open document.
The script "DoAccentuate" returns an accented word for any unaccented Latin word I send it as a string. I just need help doing a better job of looping through all the words, and then stopping the loop when the last word is reached. My current method is a bit goofy...I insert a nonesense word at the end of the document and then loop until it gets selected and accented.
Perhaps there's a better or more efficient way to go about the whole thing.
Public Sub Button5_Click(sender As Object, e As EventArgs) Handles Button5.Click
Dim document As Word.Document
document = Globals.ThisAddIn.Application.ActiveDocument
Dim mySelection = document.Application.Selection
'make sure cursor is at start of document
document.Application.Selection.HomeKey(Unit:=Microsoft.Office.Interop.Word.WdUnits.wdStory)
'insert fake word at end to stop the loop
Dim range As Word.Range
range = document.Range()
range.InsertAfter(" documentendatoris")
Do
'use MS Word's wildcard to select the first individual word as trimmed string
mySelection.Find.Text = "<*>"
mySelection.Find.MatchWildcards = True
mySelection.Find.Execute()
'replace the selected word that has been found with its accented counterpart
mySelection.Text = Accentuate.Accentuate.DoAccentuate(mySelection.Text)
Loop Until mySelection.Text = "documentendatóris"
End Sub

Well, I don't realy know if its more efficient way but you could use document.Content and range.Words collection to check all words in main story range
document = Globals.ThisAddIn.Application.ActiveDocument
Dim range As Word.Range
range = document.Content
Dim current As Integer
current = 0
Dim words As Word.Words
words = range.Words
Dim word As Word.Range
Do
current = current + 1
If current < words.Count Then
word = words(current)
If word.Text.EndsWith(" ") Then
word.Text = word.Text.Trim() + "'s "
'replace the selected word that has been found with its accented counterpart
'mySelection.Text = Accentuate.Accentuate.DoAccentuate(mySelection.Text)
Else
word.Text = word.Text.Trim() + "'s"
End If
End If
Loop Until current = words.Count
