[RESOLVED] Auto Login to webpage running javascript

I am new to programming and trying to create an application to login to a website and download a report automatically. I am stuck at the login part :(.

What i have so far:

Public Class Main

Private Property HtmlDocument As HtmlDocument

Private Property InptElmt As Object

Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
WebBrowser1.Navigate("https://secure-ausomxjna.crmondemand.com/OnDemand/user/ReportIFrameView?SAWDetailViewURL=saw.dll?Go%26Path%3D%252fusers%252fvertafore%2523bbardorf%252fAll%2bOpen%2b-%2bFinancePro&AnalyticReportName=All+Open+-+FinancePro")
'Dim webbrowser1.navigate "https://secure-ausomxjna.crmondemand.com/OnDemand/user/ReportIFrameView?SAWDetailViewURL=saw.dll?Go%26Path%3D%252fusers%252fvertafore%2523bbardorf%252fAll%2bOpen%2b-%2bFinancePro&AnalyticReportName=All+Open+-+FinancePro"

End Sub

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
WebBrowser1.Document.GetElementById("j_username").SetAttribute("value", TextBox1.Text)
WebBrowser1.Document.GetElementById("j_password").SetAttribute("value", TextBox2.Text)

The problem is i cannot hit the sumbit button. It is actually not a button by a link that is hidden and calls a javascript function

The code on the site looks like the following:

<td></td>
<td style="padding-right:1px"><table border="0" width="300px" cellpadding="0" cellspacing="0"><tr><td style="width:22px"><input name="rememberMe" type="checkbox" checked="checked" onkeypress="return checkEnterLogon(event);" /></td>
<td class="logonFont">Remember My User ID</td>
<td align="right"><table border="0" cellpadding="0" cellspacing="0"><tr>
<td onmouseout="if(className!='disableLogonScreenButtonTD'){ className='logonScreenButtonTD'};;" onmouseover="if(className!='disableLogonScreenButtonTD'){ className='logonScreenButtonTD-inv'};;" class="logonScreenButtonTD" onclick="className='disableLogonScreenButtonTD';;">
<a href="javascript:void(0)" class="loginLink" onclick="checkPreSubmit (document.logonForm); return false;" onkeypress="return checkEnterLogon(event);">Sign In</a></td></tr></table></td></tr></table></td></tr></table>
