Question

Private Sub CheckLogin()

If Failed == 3
    'show recapacha
    If Page.IsValid Then
    CheckLogin2()
    End If
End If
Else
Try
    'login code
    ' on password fail Failed+1
End Try
End If

What I have is a login form but I do not want to show the recapacha till there are 3 invalid login attempts. I’m not sure as to the best way to do that. Above is some mockup code to get an idea on where I am heading.

Answer 1

Private Sub CheckLogin()

    'after the three attempts 
    If (LoginCount = 3) Then
        'show captcha code
        Return
    End If
    'your login code if found unsuccessful increase the counter
    LoginCount += 1

End Sub

Property to increase the counter and check the number of login
attempts

Public Property LoginCount() As Integer
    Get
        If (ViewState("LoginCount") = Nothing) Then
            ViewState("LoginCount") = 0
        End If
        Return DirectCast(ViewState("LoginCount"), Integer)
    End Get
    Set(ByVal value As Integer)
        ViewState("LoginCount") = value
    End Set
End Property
