try this

In intLoopLetter variable you get the number of alphabets
       Dim xvar As String
        xvar = "abc000123a"
 
        Dim current As Integer
        Dim intLoopStrText, intLoopLetter As Integer
        xvar = xvar.ToUpper
        intLoopStrText = 0
        intLoopLetter = 0
        While (intLoopStrText < xvar.Length)
            current = Asc(xvar.Substring(intLoopStrText, 1))
            If current >= 65 And current <= 90 Then
                intLoopLetter = intLoopLetter + 1
            End If
            intLoopStrText += 1
        End While

mseit, are you trying to count the number of alphabets in the given string?
If so you can try:

Dim count As Integer = 0
For Each c As Char in xvar
    If Char.IsLetter(c) Then count += 1
Next

You get the result in variable count
0
