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

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:
And then to access the ID parameter I used $routeParams:
/* Used to display the lesson planner for customers */
app.controller("CustomerPlannerController", function ($scope, $routeParams /*, ... */) {
console.log($routeParams);
console.log($routeParams.id);
}
Using that setup, a route to /Businesses/Details/:id will display the following output in the console:
//Route to: /Businesses/Details/:id
Object {id: "1"}
1
There is already an open DataReader associated with this Command which must be closed first.
It turns out there are a few causes for this. My issue was that I was attempting to open a result set while already iterating over another one.
//Retrieve list of cart products and create list of suborders
var cartProducts = db.CartProducts.Where(cartProduct => cartProduct.CartId == userOrder.CartId);
//Loop through each cart product
foreach(var cartProduct in cartProducts)
{
//Retrieve suborder
SubOrder subOrder = subOrders.Find(x => x.BusinessId == cartProduct.Product.BusinessId);
The solution to this was pretty easy thankfully. Simply add “ToList()” to the end of the initial request:
//Retrieve list of cart products and create list of suborders
var cartProducts = db.CartProducts.Where(cartProduct => cartProduct.CartId == userOrder.CartId).ToList();
An alternative solution is to modify your connection string in order to allow multiple result multiple result sets. Simply add the following to provider part:
I’ve been mucking around with directives for that last few days and one of my requirements has been a simple timepicker. Nothing too fancy, but if anyone would like to use it – feel free.
The hours and minutes will then be updated whenever the user changes the value. If you need any other hooks it’s fairly easy to modify and there are a heap of comments.
You may also want to put the HTML in an external template. Just make the following changes to the directive (note templateURL):
The JSFiddle is probably the easiest way to see how it all works. You can simply copy it from there to your app. Alternatively, I’ve dumped the code below:
Uncondensed HTML (for those who prefer to use a template)
{{displayHours()}}
{{displayMinutes()}}
= 12" class="display">
PM
<div ng-if="hours
AM
Timepicker Directive
/*
http://www.whatibroke.com/?p=899
*/
var app = angular.module('myApp', []);
app.controller("MyCtrl", function MyCtrl($scope) {
$scope.hours = 11;
$scope.minutes = 45;
});
app.directive("ngTimeSelector", function () {
return {
restrict: 'EA',
template: '
{{displayHours()}}
{{displayMinutes()}}
= 12" class="display"> PM
<div ng-if="hours AM
',
scope: {
hours: "=",
minutes: "="
},
replace: true,
link: function (scope, elem, attr) {
//Create vars
scope.period = "AM";
/* Increases hours by one */
scope.increaseHours = function () {
//Check whether hours have reached max
if (scope.hours < 23) {
scope.hours = ++scope.hours;
}
else {
scope.hours = 0;
}
}
/* Decreases hours by one */
scope.decreaseHours = function () {
//Check whether hours have reached min
scope.hours = scope.hours = 59) {
scope.minutes = 0;
}
else {
scope.minutes++;
}
}
/* Decreases minutes by one */
scope.decreaseMinutes = function () {
//Check whether to reset
if (scope.minutes 12) {
hoursToDisplay = scope.hours - 12;
}
//Check for 12 AM etc
if (hoursToDisplay == 0) {
//Set to am and display 12
hoursToDisplay = 12;
}
else {
//Check whether to prepend 0
if (hoursToDisplay <= 9) {
hoursToDisplay = "0" + hoursToDisplay;
}
}
return hoursToDisplay;
}
/* Displays minutes */
scope.displayMinutes = function () {
return scope.minutes = 12 ? scope.hours - 12 : scope.hours + 12;
}
}
}
});
This is just a quick post to help out anyone who runs into the same problems with directives that I did today. I was able to call the controllers function from the directive, however none of the parameters were being passed.
The issue ended up being that the parameters need to be named. For instance:
app.directive('ngPlanner', function () {
return {
restrict: 'EA',
templateUrl: '/Businesses/PlannerDirective',
scope: {
lessons: "=",
business: "=",
lessonClicked: "&",
addLesson: "&"
},
replace: true,
link: function (scope, elem, attr) {
var selectedIndex = null;
console.log(scope);
console.log(scope.lessons);
scope.test = function (tester) {
selectedIndex = tester;
console.log("Directive: " + selectedIndex);
scope.lessonClicked({ lesson: selectedIndex });
}
}
}
});
/* Used for handling business details, planner, etc */
app.controller("BusinessDetailsController", function ($scope) {
//Fired when the new lesson button is clicked in the planner directive
$scope.newLesson = function (date) {
console.log("New Lesson Clicked: " + date);
}
//Fired when a lesson is clicked on
$scope.editLesson = function (lesson) {
console.log("Lesson Clicked: " + lesson);
}
});
Note particularly the scope.lessonClicked line. Instead of passing parameters normally, they should be named (scope.lessonClicked({lesson: selectedIndex}).
The naming should match that used in the HTML where your directive is added:
<ng-planner lessons=”plannerLessons” lesson-clicked=”editLesson(lesson)” add-lesson=”newLesson()” business=”true”></ng-planner>
You’ll notice that in the markup, the value is actually an index. This is pretty misleading, but Angular will actually assign the appropriate value to the model (“enabled”, “disabled”, etc).
Another thing that you can do fairly easily, is to remove the default value. Simply make the status null. You can test both these by outputting the JSON or using http://jsfiddle.net/rtR6e/5/.
I am working on a small project done in ASP.NET MVC4 and started getting the following error:
The EntityFramework package is not installed on project ”.
Get-Package : Cannot validate argument on parameter ‘ProjectName’. The argument is null or empty. Supply an argument that is not null or empty and then try the command again.

The confusing thing was that I’d used it no more than an hour ago. The following StackOverflow post reveals the issue (and the fact that I should’ve read the error more carefully):
