Public Function IsAlpha(ByVal Value As Char) As Boolean
        Return Char.IsLetter(Value)
    End Function

If you mean it contains any character you can just do a
InStr("abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ", yourstring)
If it returns true an alpha character is there.
yourstring can also be a char.
Also if you need to check for any special characters as well all you have to do is add it in the comparison string.
Of course if you only need alpha the response egl1044 wrote while i was typing will work. Mine is more helpfull when you might need things like !@#$%^&*
