Counting the Instances of a Text String

When you are working in a large document, you may want to know how many times a particular text string occurs within a portion of the document. One way you can find this information is to create a macro that will examine a selected range of text to see how many instances it contains. Consider the following macro:

Sub CountString()
    Dim MyDoc As String, txt As String, t As String
    MyDoc = ActiveDocument.Range.Text
    txt = InputBox("Text to find")
    t = Replace(MyDoc, txt, "")
    MsgBox (Len(MyDoc) - Len(t)) / Len(txt) & " occurrences of " & txt
End Sub

Select the text you want analyzed and then run the macro. It assigns the selected text to the MyDoc variable (so nothing in the actual document is affected) and then asks you to enter the text string you want to find. The Replace function is then used to replace all the instances of that string within the MyDoc variable. The text, after the replacement, is assigned to the variable t. The length of the "before" text (MyDoc) and the "after" text (t) is compared and the number of replacements calculated.
