Is this code right

I'm trying to create a prog. which allows a user to enter username and password within 20 seconds. if username/password is not entered within the time allowed prog should terminate, as well as if pwd/ username not entered corrrectly a message shold pop up. Can some one look at this code and tell me where i'm going wrong.
thank you.

Private Sub grp1_Enter(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles grp1.Enter
Dim Username As String = New String("mark")
Dim Password As String = New String("pass")
Dim intCount As Integer = New Integer()

End Sub

Private Sub txtUser_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles txtUser.TextChanged
If (txtUser.Text) = "mark" And _
(txtPass.Text) = "Pass" Then
MsgBox("Logged in...", MsgBoxStyle.Information, "Logged in...")
Else
If Not (txtUser.Text) = "mark" Then
MsgBox("worng username", MsgBoxStyle.Critical + MsgBoxStyle.OKOnly, "Auth")
Exit Sub
Else
If Not (txtPass.Text) = "pass" Then
MsgBox("wrong password", MsgBoxStyle.Critical + MsgBoxStyle.OKOnly, "Auth.")
End If
End If


End If
End Sub

Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick

End Sub

Private Sub btnExit_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnExit.Click
End
End Sub

You are verifying username and password through keychange event . It's completely wrong . It checks the data entered chr by chr . You can paste your code in a button rather than textboxchange event .

i'm trying to get the user to logon only twice but cant seem to do that cant you guide me a bit on that code

next time u post a code put it between [.vbcode] [/Highlight] tags...

Without the dot (.)

btw, thought that i posted an small example somewhere in the VB.Net area, just use search to find it

this would give the user 2 attempts , if he failed the code will stop executing and showing "Contact your......"

VB Code:

Dim intCount As Integer = 0
 
    Private Sub grp1_Enter(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles grp1.Click
        Dim Username As String = New String("mark")
        Dim Password As String = New String("pass")
 
        intCount = intCount + 1
        If intCount >= 3 Then
            MsgBox("Contact your administrator for more Info ")
            Exit Sub
        End If
 
        If (txtUser.Text) = "mark" And _
        (txtPass.Text) = "Pass" Then
            MsgBox("Logged in...", MsgBoxStyle.Information, "Logged in...")
        Else
            If Not (txtUser.Text) = "mark" Then
                MsgBox("worng username", MsgBoxStyle.Critical + MsgBoxStyle.OKOnly, "Auth")
                Exit Sub
            Else
                If Not (txtPass.Text) = "pass" Then
                    MsgBox("wrong password", MsgBoxStyle.Critical + MsgBoxStyle.OKOnly, "Auth.")
                End If
            End If
        End If
    End Sub
