How to analyse a string of characters in VBA

Question

Hi,
I need to know if a list of character contains only letters or if it contains a numeric part, or only numeric.
How can I do that ?
Thanks

WLID1966,
At first I thought it could be done with a formula in a custom field, and it probably could, but the formula would be unwieldy. Therefore I developed this little macro to do the job.
Sub chkStrforNumLet()
Dim t As Task
Dim str As String
Dim Num As Boolean, Ltr As Boolean
For Each t In ActiveProject.Tasks
    If Not t Is Nothing Then
        str = t.Name
        Num = False: Ltr = False
        For i = 1 To Len(t.Name)
            If Asc(str) > 47 And Asc(str) < 58 Then Num = True
            If Asc(str) > 64 And Asc(str) < 91 Or _
                 Asc(str) > 96 And Asc(str) < 123 Then Ltr = True
            If Num = True And Ltr = True Then Exit For
            str = Mid(str, 2)
        Next i
        If Num = True And Ltr = True Then t.Text1 = "Mixed"
        If Num = True And Ltr = False Then t.Text1 = "Numbers"
        If Num = False And Ltr = True Then t.Text1 = "Letters"
    End If
Next t
End Sub
If this answers your question, please mark it as the answer.
