title: having trouble validating input. need to verify that there is at least 1 numeric char and 1 alpha char
body: <p>As stated in description, I need to validate user input to make sure it is a minimum of 6 characters long and contains 1 numeric character and 1 character from the alphabet.</p>
  
  <p>So far, I've gotten the length validation working but cannot seem to get my numeric validation to function properly. If I enter nothing but numbers, it works, but if I put letters in IE abc123 it will not recognize that there are numbers present.</p>
  
  <pre><code>Public Class Form1
      Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
          If txtPassword.TextLength &lt; 6 Then
              lblError.Text = "Sorry that password is too short."
          ElseIf txtPassword.TextLength &gt;= 6 Then
              Dim intCheck As Integer = 0
              Integer.TryParse(txtPassword.Text, intCheck)
              If Integer.TryParse(txtPassword.Text, intCheck) Then
                  lblError.Text = "Password set!"
              Else
                  lblError.Text = "Password contains no numeric characters"
              End If
          End If
      End Sub
  End Class
