I ran into the following error while trying to publish via FTP to GoDaddy using Visual Studio 2013:
Unable to add ‘Scripts/services/OrderService.js’ to the Web site. An unknown WinINet error has occurred (code 12113)
While I wasn’t able to work out an exact cause it seems to have been triggered by my alternative Azure/TFS publishing profile. While attempting to publish to GoDaddy the Microsft login popped up. I closed it thinking that it shouldn’t be required. Logging back in seems to have resolved the issue.
In order to verify that a pay response is legitimate, PayPal provides a unique token for each request. This token can then be matched against payment confirmation requests to ensure that they aren’t being spoofed. The problem I ran into was that even the legitimate IPNs I received did not contain a pay key.
It turns out that PayPal sends two different types of IPNs. The first is configured when making the API request. The second is configured in the PayPal account under “My Account > Profile > Instant PayPal Notification”.
The first type, includes the required PayKey, the second does not. Simply configure your profile details to point to another url and everything should work!
The configuration section ‘customErrors’ cannot be read because it is missing a section declaration
I started receiving this error after I added the following elements to my Web.config file:
The problem turned out to be that the custom errors entry actually belongs under system.web. All you actually need to add it the <customErrors mode=”Off”/> part – just make sure it’s under system.web.
I used this directive to add a random background to each of my wrapper divs:
To use it in your app simply define a list of classes in your controller:
app.controller("MyCtrl", function MyCtrl($scope) {
/* A random class is picked from this list */
$scope.classes = [
//"bg-buildings",
"red",
"blue",
"yellow",
"green",
"orange",
"black",
"purple"
];
});
Then add the directive to your page (can be an existing element):
A random class will then be selected from the list and appended to the elements current list of classes (if any).
The easiest way to see how it’s done is probably just to check out the fiddle above, but there’s a code dump below if you need it:
The Random Class Directive
app.directive("ngRandomClass", function () {
return {
restrict: 'EA',
replace: false,
scope: {
ngClasses: "="
},
link: function (scope, elem, attr) {
//Add random background class to selected element
elem.addClass(scope.ngClasses[Math.floor(Math.random() * (scope.ngClasses.length))]);
}
}
});
/*

Adds a random class to element

*/
var app = angular.module('myApp', []);
app.controller("MyCtrl", function MyCtrl($scope) {
/* A random class is picked from this list */
$scope.classes = [
//"bg-buildings",
"red",
"blue",
"yellow",
"green",
"orange",
"black",
"purple"
];
});
A quick issue I ran into today, my generated migrations weren’t detecting any of the models I’d added – only changes to existing models. Unfortunately the solution was so obvious that it didn’t even come up on Google.
I had forgotten to add the table to the DBContext file… Once this was done it all worked fine.
Just a dummy implementation of a Parallel Payment and an accompanying IPN Handler using the C#/.NET SDK. Feel free to use it however you like.
//Handles PayPal IPN
public String IPN()
{
//Post back to either sandbox or live
string strSandbox = "https://www.sandbox.paypal.com/cgi-bin/webscr";
//string strLive = "https://www.paypal.com/cgi-bin/webscr";
HttpWebRequest req = (HttpWebRequest)WebRequest.Create(strSandbox);
////Set values for the request back
req.Method = "POST";
req.ContentType = "application/x-www-form-urlencoded";
byte[] param = Request.BinaryRead(Request.ContentLength);
string strRequest = Encoding.ASCII.GetString(param);
strRequest += "&cmd=_notify-validate";
req.ContentLength = strRequest.Length;
//Send the request to PayPal and get the response
StreamWriter streamOut = new StreamWriter(req.GetRequestStream(), System.Text.Encoding.ASCII);
streamOut.Write(strRequest);
streamOut.Close();
StreamReader streamIn = new StreamReader(req.GetResponse().GetResponseStream());
string strResponse = streamIn.ReadToEnd();
streamIn.Close();
if (strResponse == "VERIFIED")
{
//check the payment_status is Completed
//check that txn_id has not been previously processed
//check that receiver_email is your Primary PayPal email
//check that payment_amount/payment_currency are correct
//process payment
}
else if (strResponse == "INVALID")
{
//log for manual investigation
}
else
{
//log response/ipn data for manual investigation
}
return "";
}
//Pay for an order
public void Pay(int OrderId)
{
RequestEnvelope envelopeRequest = new RequestEnvelope();
envelopeRequest.errorLanguage = "en_US";
PaySample paySample = new PaySample();
List listReceiver = new List();
// Amount to be credited to the receiver's account
Receiver receiverA = new Receiver(Convert.ToDecimal("4.00"));
// A receiver's email address
receiverA.email = "test_buyer1@learnerlessons.com.au";
listReceiver.Add(receiverA);
// Amount to be credited to the receiver's account
Receiver receiverB = new Receiver(Convert.ToDecimal("2.00"));
// A receiver's email address
receiverB.email = "test_buyer2@learnerlessons.com.au";
listReceiver.Add(receiverB);
ReceiverList receiverList = new ReceiverList(listReceiver);
PayRequest requestPay = new PayRequest(envelopeRequest, "PAY", "http://localhost:53034/orders/cancel", "AUD", receiverList, "http://localhost:53034/orders/return");
requestPay.reverseAllParallelPaymentsOnError = true;
requestPay.ipnNotificationUrl = "http://123.123.123.123/Orders/IPN";
//Send request to paypal, retrieve payKey
PayResponse payResponse = paySample.PayAPIOperations(requestPay);
Response.Redirect("https://www.sandbox.paypal.com/cgi-bin/webscr?cmd=_ap-payment&paykey=" + payResponse.payKey);
}
I’ve been mucking around with the C# SDK for PayPal Adaptive Payments. Unfortunately the docs aren’t too great and the samples are a little confusing until you get your head around them.
One of the main issues I’ve had is working out how to configure payment request settings i.e. reverseAllparallelPaymentsOnError.
Just setting up an app that using the .NET Adaptive Payments SDK. Looking through the sandbox I was able to find the api signature, password and username but not the application ID (My Account > Overview > Account Information > API Access).
It turns out that ALL sandbox apps share the same ID:
