Displaying a Live Word Count

Word displays, on the status bar, a variety of information that can help you while you are writing. For instance, the status bar shows the number of pages in the document and the line number on the current page. One thing that would be helpful is if the status bar showed the number of words in the document, as you were typing.

Such a feature is not built in to Word, however. The status bar is not reconfigurable via a macro, other than to show or hide the entire bar or write a message to it. Coding a macro that continually wrote a message to the status bar would mean the normal information would not get shown, so a solution that uses the status bar is probably not acceptable.

It is possible to write a macro that would continuously check the word count in a document, and then display the result in another area of the document, such as the title bar or a toolbar button. Depending on the type of system you have, such a solution may not be acceptable; you will need to conduct some tests to see if it is. The internal code to calculate the word count for a document is rather slow, particularly as your documents get larger. This means that constantly checking the word count could slow down your entire system, perhaps to an unacceptable degree.

With this caveat in mind, consider the following set of macros:

Sub AutoExec()
    NumberOfWords
End Sub

Sub NumberOfWords()
    Dim lngWords As Long
    Dim myRange As Range
    With Word.Application
        If .Windows.Count > 0 Then
            Set myRange = ActiveDocument.Content
            lngWords = myRange.ReadabilityStatistics(1).Value
            .Caption = Format(lngWords, "##,##0") & " words - Microsoft Word"
        Else
            .Caption = "Microsoft Word"
        End If
        .OnTime Now + TimeValue(OnTm(lngWords)), "NumberOfWords"
    End With
End Sub

Private Function OnTm(ByVal lngWd As Long) As String
    Select Case lngWd \ 1000
        Case 0 To 10
            OnTm = "00:00:01"
        Case 11 To 20
            OnTm = "00:00:05"
        Case 21 To 30
            OnTm = "00:00:10"
        Case 31 To 40
            OnTm = "00:00:15"
        Case Else
            OnTm = "00:00:20"
    End Select
End Function

There are three macros included in this set, each of which does a different task. The first macro, named AutoExec, will run automatically whenever Word starts. Its only purpose is to call the next macro, NumberOfWords, for the first time.

The NumberOfWords macro is the workhorse of this set. It checks to see if there are any windows open in Word. If so, then it calls Word's internal coding to determine the number of words in the document. It then formats the output and displays it on the title bar for the window. If there are no windows open, then the macro simply displays "Microsoft Word" on the title bar.

The final thing that NumberOfWords does is to tell itself when to run again. It does this by using the OnTime feature of VBA, setting the restart time to be sometime within the next 20 seconds. This is where the third macro, OnTm, comes into play. It takes a look at the number of words in the current document and determines the interval between runnings of the NumberOfWords macro. If there are 10,000 or fewer words in your document, then the macro is run every second. If there are 11,000 to 20,000 words, then it is run every five seconds, and so on. The reason for this checking was covered earlier in this tip: the calculation of the word count and the formatting of the title bar information can take a while (in VBA terminology), and if your document is large, this can cause unwanted and noticeable delays in updating your document. You can, if desired, play with the coding in the OnTm function to determine the best delay breakdown for the types of documents you use.
