[2005] WebBrowser component trouble

Problem: When accessing a certain webpage through Firefox I can logout using this URL : http://www.lunarstorm.se/log/log_exit.aspx, but in Iexplore, it doesn't work, just get send to the mainpage, still being logged in, I need to find out why. I'm making a certain software that would force the logout, but it's using a VB .NET WebBrowser form (based on IE). Anyone know a solution to why the IE webbrowser form acts diffrent from Firefox in these type of cases?

Note: Doesn't work if I run IE directly either instead of using my software component.

Could you show us your code? It doesnt sound like it should be doing that.

I tried doing it through the Original IE and it seems like the site is blocking useing the URL directly more than once in a certain time. Though something in FF allows it. If the user is to click the logoff button on the site it works no matter how many times I log in / log off. So somethins is messed up.

Here's the code:

vb Code:

Public Class Form1
    Dim userName As String
    Dim password As String
    Dim count As Double
    Dim counter As Double
    Dim x As Double
    Dim y As Double
 
  Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
 
        userName = TextBox1.Text
        password = TextBox2.Text
 
        count = TextBox3.Text
        counter = 0
        ProgressBar1.Maximum = count
        countMonitor.Text = counter
 
        While counter < count
 
 
 
            WebBrowser1.Navigate("http://www.lunarstorm.se")
 
 
            Dim start As Integer
            start = My.Computer.Clock.TickCount()
            While My.Computer.Clock.TickCount() - start < 9000
 
                Application.DoEvents()
 
            End While
 
            counter = counter + 1
            countMonitor.Text = counter
            ProgressBar1.Value = counter
 
 
            WebBrowser1.Navigate("http://www.lunarstorm.se/log/log_exit.aspx")
 
            Dim start2 As Integer
            start2 = My.Computer.Clock.TickCount()
            While My.Computer.Clock.TickCount() - start2 < 7000
 
                Application.DoEvents()
 
            End While
 
 
        End While
 
    End Sub
 
    Private Sub WebBrowser1_DocumentCompleted(ByVal sender As System.Object, ByVal e As System.Windows.Forms.WebBrowserDocumentCompletedEventArgs) Handles WebBrowser1.DocumentCompleted
 
        If WebBrowser1.Url.AbsoluteUri = "http://www.lunarstorm.se/" Then
 
            Try
 
 
                WebBrowser1.Document.GetElementsByTagName("input").Item(3).InnerText = TextBox1.Text
                WebBrowser1.Document.GetElementsByTagName("input").Item(4).InnerText = TextBox2.Text
                WebBrowser1.Navigate("javascript:__doPostBack('ctl07$ctl14$ebLogin$ebLogin_a','')")
 
 
            Catch ex As Exception
 
            End Try
 
        End If
 
 
    End Sub
End class

Get rid of these:

vb Code:

While My.Computer.Clock.TickCount() - start < 9000
 
                Application.DoEvents()
 
            End While

You should take advantage of the DocumentCompleted event, navigate to the logout page from there.

Also, does this really work?

vb Code:

WebBrowser1.Navigate("javascript:__doPostBack('ctl07$ctl14$ebLogin$ebLogin_a','')")

Why should I get rid of them? I'm using the DocumentCompleted to make sure that the page is loaded before logging in, but how would I code so it waits for the page to load again before logging out?


The javascript navigating thing does work. It uses the javascript that is coded on the website for logging in. The application works all the way, logging in, but it doesn't log out, that's were the problem is.
