Network Programming in .NET

If you are developing an app or website that allows people check television guides in the UK, then this API may help you out.

First, a list of 576 TV channels from the UK can be listed via this Rest API call;

http://tv.apixml.net/api.aspx?action=channels

Then, to get details of programs to be shown on this channel, then you can use the url;

http://tv.apixml.net/api.aspx?action=program&channelid=03c9f88a54910f471bb80c039e2a8fa1

Where channelId is obtained from the previous call. The schedule is always for the next 24 hours.

This API will be built into out TV UK app for iOS: https://itunes.apple.com/us/app/tv-uk/id464570844?mt=8

SMTPjs.com is a javascript library that allows you send email through Javascript. – You still need access to a outgoing mail (SMTP) server, but this makes life a little easier for your JS apps.

Today, we released v2.0.1 of the library, which has a few important fixes

• The message body is no longer limited in size
• There is now an optional callback parameter, that allows your code continue after the email is sent.
• Attachments can be sent in base 64 format (dataURI) to the library.

Previous versions of the library will continue to be functional, but we recommend upgrading to the latest version.

Callback feature:

Depending on whether you use a stored token, or send your SMTP credentials with every request, then you use one of the two following blocks of code:

Email.send(“from@you.com”,
“to@them.com”,
“Subject”,
“Body”,
“smtp.server.com”,
“username”,
“password”,
function done(message) { alert(“sent”) }
);

or, when using stored credentials;

Email.send(“from@you.com”,
“to@them.com”,
“Subject”,
“Body”,
{
token: “your-token”,
callback:function done(message) { alert(“sent”) }
});

DataUri Attachments

Previously, in order to send an attachment with this script, then the file you needed to send needed to be already hosted online. This, may not be ideal, if you wanted your user to select a file from their device, or otherwise dynamically generate the file to be sent.

So, let’s imagine we want the user to select a file to be sent from their device, we add a form element as follows;

<input type=”file” id=”fileupload” onchange=”uploadFileToServer()” />

Then define the function uploadFileToServer as follows:

function uploadFileToServer() {
var file = event.srcElement.files[0];
console.log(file);
var reader = new FileReader();
reader.readAsBinaryString(file);
reader.onload = function () {
var datauri = “data:” + file.type + “;base64,” + btoa(reader.result);
Email.sendWithAttachment(“from@you.com”,
“to@them.com”,
“Subject”,
“Body”,
“smtp.server.com”,
“username”,
“password”,,
datauri,
function done(message) { alert(“Message sent OK”) }
);
};
reader.onerror = function() {
console.log(‘there are some problems’);
};
}

If you have a multi-lingual app or website that needs to show a drop down list of country names, then it suddenly adds 195 words to your translation file, which is going to make your translation word count shoot up suddenly.

Surely, someone else has done this already?, yes, they have. The Unicode consortium have a public file that you can download that contains a list of countries, and lots of other information translated into many different languages; here; http://unicode.org/Public/cldr/1.7.0/core.zip

I extracted the two letter files ({language}.xml) from core/common/main, removed the dtd definition, and put it in to a folder named /data/localisation off the root of my website.

public static string Country(string code, string culture)
{
// Source: http://unicode.org/Public/cldr/1.7.0/core.zip
var locale = new CultureInfo(culture).TwoLetterISOLanguageName.ToLower();
var strLocalXmlFile = HttpContext.Current.Server.MapPath(“/data/Localisation/” + locale + “.xml”);
var xdoc = new XmlDocument();
xdoc.Load(strLocalXmlFile);
var xn = xdoc.SelectSingleNode(“//territory[@type='” + code + “‘]”);
return xn.InnerText;
}

Then you can call Country(“GB”,”sv-SE”) to get Storbritannien

Of course, there is many more things that you may want to translate, and nothing is better than a human translator, which I’d recommend OutsourceTranslation.com to find one.

IAP or In app Purchases is now the most popular way App developers get paid for their apps. Most IAPs don’t actually incur added cost the developer when used, such as unlocking extra levels, or power ups, but some activate real-world services, and can incur added server costs to the developer – such as extra file storage, or paid-for API calls.

This is why you really need to ensure that you validate your IAP receipt from apple, to ensure that it has indeed come from apple, and not a replay attack from someone else’s IAP.

I received this IAP receipt that failed validation this morning:

Running it through my IAP receipt validator I got this;

Where I’ve highlighted com.zeptolab.ctrbonus.superpower1 – Which looks like ZeptoLab’s Cut the Rope Super Power 1 from 2012!,  Not the IAP I was expecting at all.

Thankfully my validator code spotted this.

Here’s the code for decoding an Apple receipt in c#

private const string urlProduction = “https://buy.itunes.apple.com/verifyReceipt&#8221;;
private const string urlSandbox = “https://sandbox.itunes.apple.com/verifyReceipt&#8221;;

private string Verify(string receipt, string serviceUrl, string sharedSecret)
{
var json = string.Format(“{{\”receipt-data\”:\”{0}\”,\”password\”:\”{1}\”}}”, receipt, sharedSecret);
var wr = WebRequest.Create(serviceUrl);
wr.ContentType = “text/plain”;
wr.Method = “POST”;
var sw = new System.IO.StreamWriter(wr.GetRequestStream());
sw.Write(json);
sw.Flush();
sw.Close();
var wresp = wr.GetResponse();
if (wresp != null)
{
var sr = new System.IO.StreamReader(wresp.GetResponseStream());
var response = sr.ReadToEnd();
sr.Close();
return response;
}
return “no-data”;
}

If you have multiple users on Sage, who are not on the same network – i.e. perhaps working from home. Then you will want to move the sage data to a remote server, so that all users can access the same sage data.

1. Rent a WINDOWS server. a VPS should do, OVH do one for £9/month
2. Set up an VPN to the windows server. Not so easy, glossing over this point
3. Close Sage, and copy the Company.000 folder to the server, and share it with a network share
4. Ensure you can see this folder from Windows explorer with \\[Server]\[Share]\Company.000
5. Now, install the Sage Data Services software on the server. You can download this as part of the trial software from Sage, or just here 
6. Find the COMPANY file on your local machine, and open it in notepad, and change the C:\programdata\…\Company.000 file to \\[Server]\[Share]\Company.000
7. Re-open Sage

So, if you use Stripe on your website, but you get the odd request from a customer that’s not a standard option of your website. How do you accept a once-off custom payment via stripe, we have an app for that, which you can download here; https://creditcard.apixml.net/

But, if you’d like to use your browser rather than an app, you can do that too. Go to https://creditcard.apixml.net/

• Click on “Accept a payment online”
• Click on “Sign on” on the stripe window
• Enter your stripe username and password.
• Press “Sign into your account”
• The window will close, and return to the previous page, with a popup open
• Enter the amount, currency, and card details into the box provided
• Then press “Pay now”
• You should then see an alert saying the payment has succeeded after a few seconds
• The money is now in your stripe account.

If you wanted to create an app that allows commuters in Ireland feel safe getting into a Taxi, you can use this API to check if the taxi is legitimately registered. (And it’s free)

Here’s the API endpoint;

http://ie.carregistrationapi.com/api/bespokeapi.asmx?op=CheckIrishTaxi

And here is a sample response from 05MH6068

<IrishTaxi xmlns:xsd=”http://www.w3.org/2001/XMLSchema“ xmlns:xsi=”http://www.w3.org/2001/XMLSchema-instance“ xmlns=”http://Regcheck.org.uk/“>

<LicenceNumber>T30041</LicenceNumber>

<Expiry>09/02/2018</Expiry>

<LicenceHolder>PATRICK GERAGHTY</LicenceHolder>

</IrishTaxi>

This may be built into the main API available here; http://ie.carregistrationapi.com

You can now verify if a car is registered for private hire via it’s number plate in London via TFL, and here’s a handy API for it here;

https://www.regcheck.org.uk/api/bespokeapi.asmx?op=CheckLondonTaxi

You can use LM58FXO as an example, returning;

This is an experimental service, in consideration for RegCheck.org.uk , or as a tool for http://listoftaxis.info/

NHTSA, the “National Highway Traffic Safety Administration”, which allows users the option to search for vehicle recalls by manufacturers, where a serious safety flaw is discovered.

You can query this API for free via this URL;

http://www.vehicleregistrationapi.com/api/bespokeapi.asmx/CheckRecalledVIN?vin=JTHCE96S170011951

Where JTHCE96S170011951 is a VIN number for a vehicle that is subject to recall.

This is an experimental data source, but could be used in conjunction with data from  http://www.vehicleregistrationapi.com/  to determine recalls based on a car registration number.

IAP Subscriptions are great, they allow you take recurring payments from your customers, so that you can make an on-going income from a customer that continues to use your service.

However, accepting a subscription, it’s also important to know when the subscription is cancelled, so that you can stop providing your service to the customer.

First thing is to define a callback with the “Subscription Status Url”, which you can find under your app in iTunes Connect, under App Information > General Information.

This URL will be sent some JSON data using HTTP POST, and the format of the requests are as follows;

First, the Intial buy, as follows;

{
“latest_receipt”: “….”,
