VB.Net

[TheDruid]

I've seen a few requests from people stuck trying to use the new API with VB.net.
I've been messing around with it for a couple of weeks now, and I just feel like I'm starting to make some progress.

There are a few VB-specific 'gotchas' that had me stuck...

None of my code is particularly great, and it's just a bunch of routines right now, rather than an application, but I'm happy to post some snippets if anyone's interested?
(might save someone some time)

Hi that would be brilliant
I had a quick look myself and did not pursue due to the fact we may have to pay (Seems ok for a few more months now)
I never got to the be able to Log In and the Excel thingy didn't work
Any sort of Basic example would be very much appreciated
Log in and Show my Balance would be cool
Cheers for your post (This thread maybe better in NET section if you dont mind me saying)
Thanks again
Dave

Thanks TheDruid, it would be greatly appreciated.

Just a question, are you building response objects for every request and then using JSON.net to dump the response in the objects?

Hi Dave

I've been having problems getting started with the new API, but I can at least help with the login.

I'm using Visual Studio Express 2013 for Windows

1. Create a new windows forms application (File>New Project>Windows Forms Application)

I called mine API_NG_EXAMPLE

2. You will need to increase the size of Form1 to accomodate the controls you will be using.

3. Add a webBrowser (Webbrowser1 in my code). Set Visible to True, ScriptErrorsSuppressed to False.

4. Add a login Button (BtnLogin in my code).

5. Add a label to display the sessiontoken when acquired (Lblsessiontoken).

The code is below - it's quick and dirty but will get you a session token. You will as a minimum need to edit the Appkey declaration to use your own application key.

Public Class Form1
    ' Your App key
    Public Appkey As String = "<your app key goes here>"
    Public sessiontoken As String = "Not Logged In"
    Public loginurl As String = "https://identitysso.betfair.com/view/login?product=" & Appkey & "&url=https://www.betfair.com"

    Private Sub Btnlogin_Click(sender As Object, e As EventArgs) Handles Btnlogin.Click
        WebBrowser1.Select()
        WebBrowser1.Visible = True
        WebBrowser1.Navigate(loginurl)
    End Sub

    Private Sub WebBrowser1_DocumentCompleted(sender As Object, e As WebBrowserDocumentCompletedEventArgs) Handles WebBrowser1.DocumentCompleted
        ' On embedded web browser response get cookie
        Dim cookies As String = Me.WebBrowser1.Document.Cookie
        'check that we are not already logged in
        If sessiontoken = "Not Logged In" Then
            If cookies IsNot Nothing Then
                ' successful login will return session token
                Dim ind As Integer = cookies.IndexOf("ssoid=")
                If ind > 0 Then
                    ' we have session token
                    Dim tmp As String = cookies.Substring(ind + "ssoid".Length)
                    sessiontoken = tmp.Substring(0, tmp.IndexOf(";"))
                    Lblsessiontoken.Text = sessiontoken
                    WebBrowser1.Visible = False
                    ' need to start keepalive timer here!
                End If
            End If
        End If
    End Sub
End Class

No apologies for poor style in the code - and I'm sure there is a better way of extracting the sessiontoken from the cookie, but I have tried to make the method easy to follow.
I hope this helps,

Paul
