VBNet Sample (Yes really)

So I have to call this every 4 hours then to maintain login state? https://identitysso.betfair.com/api/keepAlive

**jabe** · 10-09-2016, 05:27 AM

Apparently so; however, given the accuracy of timers on PCs, I'd do it a bit sooner. Maybe every 3 hours or 200 minutes or something. Try it and see.

**SimonN** · 11-09-2016, 09:39 PM

Oh right - thanks Jabe - didn't realise server timers not accurate but yes in any case that makes good sense to call earlier than 4 hours.. cheers - how's your projects going, bud?

Hi All,

Have taken over an old app and am trying to get it functionaing as required. Looking at some of the prior posts I'm learning slowly.

So I have copied the following, but although it is returning the prices and available stakes into the string, it's not letting me DeserializeObject correctly, so they are not showing in my object.

I have copied the Market Book class, but guess I must be missing something fairly basic.

All help is much appreciated.

Code:

Dim strBookRequest As String = "{""jsonrpc"": ""2.0"", ""method"": ""SportsAPING/v1.0/listMarketBook"", ""params"": {""marketIds"":[""" & tabMarkets.SelectedTab.Name & """],""priceProjection"":{""priceData"":[""EX_BEST_OFFERS"",""SP_AVAILABLE""],""exBestOffersOverrides"":{""bestPricesDepth"":1} }}, ""id"": 1}"
        ''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''
        Dim ListMarketBookResponse = CreateRequest(UseAppKey, GetSessToken, strBookRequest)
        Try '
            'Get the Response and convert the Text to Classes from MarketBook
            Dim jsonBookObject = Newtonsoft.Json.JsonConvert.DeserializeObject(Of MarketBook)(ListMarketBookResponse)

I've been using a different serialiser, but this should show you the idea.

This is my ClassMarketBook class definition

Code:

Public Class ClassMarketBook ' The dynamic data in a market
    Public marketId As String           ' The unique identifier for the market
    Public isMarketDataDelayed As Boolean ' True if the data returned by listMarketBook will be delayed. The data may be delayed because you are not logged in with a funded account or you are using an Application Key that does not allow up to date data.
    Public status As MarketStatus  ' The status of the market, for example ACTIVE, SUSPENDED, SETTLED, etc.
    Public betDelay As Integer          ' The number of seconds an order is held until it is submitted into the market. Orders are usually delayed when the market is in-play
    Public bspReconciled As Boolean     ' True if the market starting price has been reconciled
    Public complete As Boolean          ' If false, runners may be added to the market
    Public inplay As Boolean            ' True if the market is currently in play
    Public numberOfWinners As Integer   ' The number of selections that could be settled as winners
    Public numberOfRunners As Integer   ' The number of runners in the market
    Public numberOfActiveRunners As Integer ' The number of runners that are currently active. An active runner is a selection available for betting
    Public lastMatchTime As DateTime ' The most recent time an order was executed
    Public totalMatched As Double ' The total amount matched
    Public totalAvailable As Double ' The total amount of orders that remain unmatched
    Public crossMatching As Boolean ' True if cross matching is enabled for this market.
    Public runnersVoidable As Boolean   ' True if runners in the market can be voided
    Public version As Long              ' The version of the market. The version increments whenever the market status changes, for example, turning in-play, or suspended when a goal score.
    Public runners() As ClassRunner     ' Information about the runners (selections) in the market.
End Class

Note that it includes ClassRunner, for which a class definition is also needed, and MarketStatus, which is an enum and needs defining somewhere. ClassRunner also has elements defined in further classes and enums, all of which must be defined.

I have a further class called ClassListMarketBookResult, into which the returned string is deserialised:

Code:

Public Class ClassListMarketBookResult
    Public jsonrpc As String
    Public result() As ClassMarketBook
End Class

I'm using JavaScriptSerializer, which requires this statement

HTML Code:

Imports System.Web.Script.Serialization

before the start of any class (Form1, in my case) that uses it.

Whenever I use it, I need a definition:

Code:

Dim jss As New JavaScriptSerializer() 'JSON serialiser

And to deserialise, I do this

Code:

odds = jss.Deserialize(Of ClassListMarketBookResult)(inrec)

where odds is defined like this:

Code:

Public odds As New ClassListMarketBookResult

You may well need to specifically define your jsonBookObject as a New MarketBook or something that includes the MarketBook class. I begin all my class names with the word Class so I know what they are.

This might be enough to help you past your problem, but let us know if it doesn't, and what you did manage to get done.

Thanks Jabe. I have the following classes (copied from an earlier post). I think something is maybe missing from in there beacuse when I try the following I don't get the prices back from the string.

Dim jsonBookObject = Newtonsoft.Json.JsonConvert.DeserializeObject(Of MarketBook)(ListMarketBookResponse)

Try

Dim jsonBookObject as MarketBook = Newtonsoft.Json.JsonConvert.DeserializeObject(Of MarketBook)(ListMarketBookResponse)

Might not make a difference - I don't know to what extent VB.Net knows to make the Dimmed item the same as the item value being assigned to it.

I'll try putting your code into a program later so I can see if I can work out why it's not doing as you want.

**LordRom** · 03-10-2016, 02:34 PM

Code:

With jsonBookObject.Result(0).Runners(i).ExchangePrices

It's the exchangeprices that doesn't exist in the object.

Might be the code in your listMarketBook request then, if the rest is working okay.

This is the line from mine that sets up the JSON request string

Code:

Dim intext = """marketIds"" : [" & marketId & "], ""priceProjection"" : {""priceData"": [""EX_BEST_OFFERS""],""virtualise"":""true""}"

See if using these parameters helps.

I've put your code into a program and deserialised the JSON string.

I added these three lines after the DeserializeObject statement:

Code:

Dim c1 = jsonBookObject.Result(0).Runners(0).ExchangePrices.AvailableToBack.Count
Dim c2 = jsonBookObject.Result(0).Runners(0).ExchangePrices.AvailableToBack(0).Size
Dim c3 = jsonBookObject.Result(0).Runners(0).ExchangePrices.AvailableToBack(0).Price

They have values 3, 12, 3, which is probably what you want, and I only used your code.

Could you please share your classes for the deserealise object of MarketBook Jabe.

I have the data in the string returned, but it gets lost when converting.

Thanks for your time.

Can someone explain all about these certificates. I am really ignorant, lol.

So you can call them on any machine for your certificated logon. You can change your account password without having to regenerate your certificate?

How does it all work? What's the point, really?

Apologies and thanks.

Thanks for your time.

They were your classes.

I'll tell you what I put where in my program.

I'm using the Visual Studio 2015 Community edition.

1. I started a new project - it's a Windows Form Project (but doesn't do anything GUI at all).

2. I did nothing at all to the form.

3. Via Project, Manage NuGet Packages, I installed the NewtonSoft JSON converter package.

4. In the Form1_Load, I assigned your JSON string to a string (see 5), set up a new JSONBookObject, as you did, deserialising your string, and added a few lines to check the values. I put your classes in the Form1 class. I added the Includes statements to the top of Form1.vb.

5. I put your JSON string into NotePad, changed " to "" throughout, added " at each end of the string, and assigned it to inString.

This is all that is in Form1.vb

Code:

        Dim jsonBookObject = Newtonsoft.Json.JsonConvert.DeserializeObject(Of MarketBook)(inString)
        Dim c1 = jsonBookObject.Result(0).Runners(0).ExchangePrices.AvailableToBack.Count
        Dim c2 = jsonBookObject.Result(0).Runners(0).ExchangePrices.AvailableToBack(0).Size

        Dim pauseHere = "wait!"
    End Sub
End Class

5. I added a breakpoint on the line where pauseHere is defined so I could check the values in c1, c2, and c3. Then I ran it.

So you can call them on any machine for your certificated logon. You can change your account password without having to regenerate your certificate?

How does it all work? What's the point, really?

Apologies and thanks.

I haven't done it, but it would be useful for automation. If your program fails, you can have it restart without your presence. Ideal for bots.

VBNet Sample (Yes really)
