Hi Experts,

I want to auto fill the username and password fields of a website login page using the document Object Model. The website main page contains one frame which contains the username and password fields. see attached code for iframe tag of the login frame and the login form code from the login frame. Thanks.
<iframe id="iframe" name="iframe" src="https://www.Domain.com?action=login_iframe"></iframe>
 
 
<form name="fmLogin" action="https://www.Domain.com" method="post">
    <input type="hidden" name="action" value="do_login" />
    <input id="username" name="Username" type="text" value="" />
    <input id="password" name="Password" type="password" value=""/>
    <a id="login" href="#" onclick="go_login();return false" title="Login">Login</a>
</form>

Sorry, I forgot to mention I am using the old axWebBrowser control not the newer WebBrowser control.

why? if you plan to allow someone in with no credentials supplied then why use a username/password pair at all?
Just set a cookie with authenticated=true and have the login page check if authenticated=true?
If so then welcome else redirect.

I may understand better if you explained why you want to allow access to a password protected area without anyone having to specify a password.
axWebbrowser?

Hi QPR,

Sorry, I must have worded the question wrongly. Take a look at the following website

http://www.paddypower.com/bet

I want to login to this site. So I require the name and password fields filled and the login button clicked programmaticaly from my VB.Net application (probably) using the Document Object Model. Thanks.

Here is a VB.Net 2005 example of how to open up Google and then search for "Idle_Mind":
(not sure how to apply it to your page...I'm not good with web stuff!)
Public Class Form1
 
    ' Click on Project --> Add Reference --> COM Tab --> Select "Microsoft Internet Controls".
 
    Private loggedIn As Boolean = False
    Private WithEvents IE As SHDocVw.InternetExplorer
 
    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        If Not (IE Is Nothing) Then
            IE.Quit()
            IE = Nothing
        End If
 
        loggedIn = False
        IE = New SHDocVw.InternetExplorer
        IE.Visible = True
        IE.Navigate2("http://www.google.com")
    End Sub
 
    Private Sub IE_DocumentComplete(ByVal pDisp As Object, ByRef URL As Object) Handles IE.DocumentComplete
        If Not loggedIn Then
            loggedIn = True
            IE.Document.All.Item("q").Value = "Idle_Mind"
            IE.Document.All("btnG").Click()
        End If
    End Sub
 
    Private Sub IE_OnQuit() Handles IE.OnQuit
        IE = Nothing
    End Sub
 
End Class
