"Val" Function not returning numeric value?

The "Val" statement is not doing what I think it should. The expected value of the "cb.Name" each time the MessageBox statement is executed can range from "cbo11" to "cbo46". However, each time the MessageBox shows a value of 0. I tried using the statement of "Val(cb.Name)" and that produced the same. I just need to show the numeric portion of the cb.Name.

    Private Sub cbo_Click(sender As Object, e As EventArgs) Handles cbo.Click
        Try
            Dim cb As CheckBox = DirectCast(sender, CheckBox)

            EH.ErrorMessage = String.Empty

            MessageBox.Show(Val(CStr(cb.Name)))

        Catch ex As Exception
            EH.ErrorMessage = "Form3/cbo_Click() - " & ex.Message & "...Contact Engineering!" & "~E"
        End Try

        EH.ProcessMessages(Me, Me.sbr, EH.ErrorMessage)
    End Sub

converting cb011 to numeric will return 0. this function does not remove non-numeric characters from it

maybe you can try:
dim number = val(Regex.Replace(cb.Name,"[^0-9]",""))

Hi BlakeMcKenna;

You could use this first version which will display the digits in the name where ever they are.

MessageBox.Show(Regex.Match(cb.Name, "\d+").ToString())

Or if the format of the name is always going to be the same you could use this one.

MessageBox.Show(cb.Name.SubString(3))
