Random sample of words from a Word document

Hi experts!

I am writing a Word VBA macro to show various Grade Level indexes and one of them requires a random sample of 150 words from a Word doc. What would be the best way to randomly choose those 150 words?

Thanks!

Here is code that will do that.
Sub RandomWords()
Dim colWords As New Collection
Dim intWord As Integer
Dim x As Integer
Const MAX = 150

With ThisDocument
    Do Until colWords.count = MAX
        intWord = Int((MAX - 1 + 1) * Rnd + 1)
        On Error Resume Next
        colWords.Add .Words(intWord), .Words(intWord)
        On Error GoTo 0
    Loop
End With

For intWord = 1 To MAX
    Debug.Print colWords(intWord)
Next

End Sub

Open in new window


You should also place the command Randomize somewhere in your code where it only will be done once.

Hi Martin!

I tried this and it didn't work. Is some code missing, you DIM x but x isn't used anywhere in the macro.

The x variable isn't needed.

When you say "it didn't work", what do you mean? Did you get an error message?
Did you look in the Immediate Window via Ctrl+g?

Open the attached doc, go to 'ThisDiocument' and run the macro that you'll find there. (You should insert a module and move the code there. And until you add the Randomize line the results will probably always be  the same.

Oh, in that sample I just posted you'll need to change the Const to something less than 150 since there aren't 150 words in the doc.

Interesting. When I run it from THIS DOCUMENT it works but when I run the exact same code from a MODULE in my NORMAL.DOT it just churns. Is the reference to THIS DOCUMENT the problem?

Yes, change ThisDocument to ActiveDocument.Content

Thanks! I tweaked it as you said and it works. Now I am just going to play around with it since it is slow. Have a great day.

In that case look for samples of code that use a Dictionary object rather than the Collection object.

In any case you’re welcome and I’m glad I was able to help.
