Below is what I have for counting vowels in a sentence how do I get it to count the number of words in the sentence? After I get the total word count I need a message box to show the count then reverse the sentence and put it in backwards into the text box.

VB

Public Function CountVowels(ByVal strSentence As String, ByRef intVowels As Integer) As Integer
        Dim intIndex As Integer
        Dim strCurrentLetter As String
        strSentence.ToLower()

        For intIndex = 0 To strSentence.Length - 1
            strCurrentLetter = strSentence.Substring(intIndex, 1)
            If strCurrentLetter = "a" Or strCurrentLetter = "e" Or strCurrentLetter = "i" Or strCurrentLetter = "o" Or strCurrentLetter = "u" Then
                intVowels += 1
            End If
        Next
        Return intVowels
    End Function

The easiest way is to use string.Split:

Dim text As String = "the quick, brown fox,jumps over the lazy dog"
Dim words As String() = text.Split(New Char() {" "C, ","C, "."C, "?"C, "!"C}, StringSplitOptions.RemoveEmptyEntries)
Dim i As Integer = words.Length

You can then rebuild the parts backwards as a sentence and display that in a MessageBox. I won't give you that code: You should do some of your own homework! :laugh:
