Can't login to website (VB.net browser) - vb.net

Question

I try to login here: http://www.swagbucks.com/p/login
I've tried the following methods:
Private Sub Button2_Click(sender As Object, e As EventArgs) Handles Button2.Click
For Each element As HtmlElement In WebBrowser1.Document.GetElementsByTagName("input")
If element.Id = "sbxJxRegEmail" Then
Dim i = 0
Dim strLine = TextBox2.Text
element.OuterText = strLine
End If
If element.Id = "sbxJxRegPswd" Then
Dim i = 0
Dim strLine = TextBox3.Text
element.OuterText = strLine
End If
Next
End Sub
and then I tried this
WebBrowser1.Document.GetElementById("sbxJxRegEmail").SetAttribute("value", TextBox2.Text)
WebBrowser1.Document.GetElementById("sbxJxRegPswd").SetAttribute("value", TextBox3.Text)
WebBrowser1.Document.GetElementById("loginBtn").Focus()
WebBrowser1.Document.GetElementById("loginBtn").InvokeMember("click")
What happens is that the text is entered, but on the browser, it's not really there. It's hard to explain, but basically the username and password are just floating on top of the text boxes like some sort of ghost text and when I then click it, it disappears.
How do I fix this?

It's possible that they are masked inputs, probably need to set the inner text of those fields like so...
WebBrowser1.Document.All("Username").SetAttribute("value", "myusername")
WebBrowser1.Document.All("Password").SetAttribute("value", "mypassword")
Dim elements As HtmlElementCollection = (WebBrowser1.Document.All.GetElementsByName("Password"))
For Each element As HtmlElement In elements
element.InnerText = "mypassword"
Next
'You may have to do the same for your username/email
