VB.NET Loginsytsem

i assume your trying to login to a website or forum etc.
to do you gonna have to use elements to your advantage the webbrowser control in the tool box will be your friend XD
ill use yourforum.com as example and also a simple review of what it should look like

Code:

'first thing first navigate to the forum or website
webbrowser1.navigate("yourforum.com")

'next double click one the webbrowser in the form designer to get document 'complete  event, something like this!

Private Sub WebBrowser1_DocumentCompleted(sender As Object, e As WebBrowserDocumentCompletedEventArgs) Handles WebBrowser1.DocumentCompleted

' in this tut we use elements to login to a website in the background

'you noticed "GetElementById("password")" in this case password is the id and how do we find it?

'first right click on the button or textbox on the and click inspect elements(chrome for this tut)

' if you see something like id="test" or name="testname" then test or testname is the id

        WebBrowser1.Document.GetElementById("username").InnerText = TextBox1.Text

'innertext gets the value of the textbox(not sure havnt tested yet :P)
        WebBrowser1.Document.GetElementById("password").InnerText = TextBox2.Text

' and in this one we raised and event which should click the button with the name "login"
        WebBrowser1.Document.GetElementById("login").RaiseEvent("click")
    End Sub

'you can use the above example to get the nickname of the user by simply using getelementbyid

Note this is just a simple overview if i gave you the direct answer the is no guarantee you will just copy and paste and learn nothing :p
