How to count alphabets in a sentence?

[Awesomeg]

How do you count how many alphabets there are in a sentence? I did a search and found only "how to count how many characters in the whole script" but not how many alphabets/characters are there in a sentence.

Simly select the range you want the stats for, then click on the 'Word Count' button on Word's status bar.

The following macro will count the unique occurrences of each character in a string thus
Lorem will have five unique characters and Lorem ipsum will have ten unique characters (including the space). mummy will have three unique characters.

Sub CountUniqueChars()
Dim Col As Collection
Dim oRng As Range
Dim i As Integer
    If Len(Selection.Range) > 0 Then
        Set oRng = Selection.Range
        Set Col = New Collection
        On Error Resume Next
        For i = 1 To Len(oRng)
            Col.Add Mid(oRng.Text, i, 1), Mid(oRng.Text, i, 1)
        Next i
        MsgBox Col.Count
    Else
        MsgBox "Nothing selected"
    End If
lbl_Exit:
    Set Col = Nothing
    Exit Sub
End Sub
