Make A Webbrowser Login On A Site (filling Textbox And Clicking Login)?

I've been trying to make a app that logs into a website. So far it didn't work for me.I have trouble because:

- The "pin" (username) box on the site doesn't have an ID. (Can't use getelementbyid)

- The picture doesn't have an ID either

Codes I've tried:

With WebBrowser1.Document
.All("pin").InnerText = "mypinhere"
End With
End Sub

This should have, in my opinion, filled in the textbox. Now I need to click the login button?Also I found this in the source of the site:

<img src="/media/img/text_AccountPin.gif" alt="Account Pin" width="93" height="10" border="0"> <input type="text" name="pin" class="form" size="15"> </p>

As we can see, it says

name="pin"

So I should be able to use "getelementbytagname" right?Also, the formId is logmein (log me in)

<form id="logmein"....

This is what I came up with:

Dim webbrowserDocForm As HtmlElementCollection = WebBrowser1.document.GetElementsByTagName("logmein")
For Each curElement As HtmlElement In webbrowserDocForm
Dim controlValue As String = curElement.GetAttribute("Value").ToString

[code]....

in the next code it's tagname is "input" or "text"? Because I found:

<input type="text" name="pin" class="form" size="15"> </p>

Code for filling in:

webbrowserDocForm = WebBrowser1.document.GetElementsByTagName("text")
For Each curElement As HtmlElement In webbrowserDocForm
Dim controlName As String = curElement.GetAttribute("name").ToString

[code]....

It doesn't give me any errors no more, but it doesn't work either.
