Help Inputting text to hidden element

[pablo989]

Im making a simple program to log into a website I subscribe too and check if I have any mails.

However im getting stuck when trying to input the username field

this is the code for the username field:

'<input type="hidden" value="qfqovig" name="actualval">

And this is the code ive been attempting to use, however it does not pass the username into required field. I use the same type of code to input the password and it works fine.

Dim theElementCollection As HtmlElementCollection = Me.WebBrowser1.Document.GetElementsByTagName("input")
        For Each curElement As HtmlElement In theElementCollection
            Dim controlName As String = curElement.GetAttribute("name").ToString
            If controlName = "actualval" Then
                curElement.SetAttribute("Value", TextBoxuser.Text)
            End If
        Next

Ive tried a few variations of the above code, but none seems to work. I should not im still learning VB.

Any ideas ?
