VB.NET 2008 - Input to data to website controls and download results - vb.net

Question

this is my first Q on this website so let me know if I have missed any important details, and thanks in advance.
I have been asked to access a website and download the results from a user-inputted form. The website asks for a username/password and once accepted, several questions which are used to generate several answers.
Since I am unfamiliar with this area I have set up a simple windows form to tinker around with websites and try to pick things up. I have used a webbrowser control and a button to use it to view the website in question.
When I try to view the website through the control, I just get script errors and nothing loads up. I am guessing I am missing certain plug-ins on my form that IE can handle without errors. Is there anyway I can identify what these are and figure out what to do next? I am stumped.
The script errors are:
"Expected identifier, string or number" and
"The value of the property 'setsection' is null or undefined"
Both ask if I want to continue running scripts on the page. But it works in IE and I cannot see why my control is so different. It actually request a username and password which works fine, it is the next step that errors.
I can provide screenies or an extract from the website source html if needed.
Thanks,
Fwiw my code is:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
'WebBrowser1.ScriptErrorsSuppressed = True
WebBrowser1.Navigate("http://website.com")
'WebBrowser1.Navigate("http://www.google.com")
End Sub

Answer 1

Thanks for Noseratio I have managed to get somewhere with this.
Even though the errors I was getting seemed to be related to some XML/Java/Whatever functionality going askew it was actually because my webbrowser control was using ie 7.0
I forced it into using ie 9 and all is now well. So, using my above example I basically did something like this:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
'WebBrowser1.ScriptErrorsSuppressed = True
BrowserUpdate()
WebBrowser1.Navigate("http://website.com")
'WebBrowser1.Navigate("http://www.google.com")
End Sub
Sub BrowserUpdate()
Try
Dim IEVAlue As String = 9000 ' can be: 9999 , 9000, 8888, 8000, 7000
Dim targetApplication As String = Process.GetCurrentProcess.ToString & ".exe"
Dim localMachine As Microsoft.Win32.RegistryKey = Microsoft.Win32.Registry.LocalMachine
Dim parentKeyLocation As String = "SOFTWARE\Microsoft\Internet Explorer\MAIN\FeatureControl"
Dim keyName As String = "FEATURE_BROWSER_EMULATION"
Dim subKey As Microsoft.Win32.RegistryKey = localMachine.CreateSubKey(parentKeyLocation & "\" & keyName)
subKey.SetValue(targetApplication, IEVAlue, Microsoft.Win32.RegistryValueKind.DWord)
Catch ex As Exception
'Blah blah here
End Try
End Sub
