I'm trying to implement a shopping cart tracking system using pdt with C#.
the trouble i have is finding an example of the paypal succes postback, especially in case of multiple items !
Any help woul be appreciated (some code will be much better :D)!
Thanks

I believe this book has some good examples.

I want to check each page values from the API and against the values to change the color of the map marker.
This is my API: http://194.141.118.43:3001/?id=0 where id is from 0 to 16
I want:
if from ?id=0 AL = 1 the marker should be green
if from ?id=0 AL = 2 the marker should be yellow
if from ?id=0 AL = 3 the marker should be orange
if from ?id=0 AL = 4 the marker should be red
So I want to check for all 17 stations (from ?id=0 to ?id=16)
I am currently checking the property Alertlevelwebsite in this method with this API: http://194.141.118.43:3001/stations, But now I have to check all the values from this address for each pin and I have to put a color for the largest value for each pin.
http://194.141.118.43:3001/?id=0 (from 0 to 16)
I use this example from xamarin.forms.maps - https://learn.microsoft.com/en-us/samples/xamarin/xamarin-forms-samples/workingwithmaps/ and in CustomMapRenderer class I try to change the colors in this method:
protected override MKAnnotationView GetViewForAnnotation(MKMapView mapView, IMKAnnotation annotation)
{
MKAnnotationView annotationView = null;
if (annotation is MKUserLocation)
return null;
var customPin = GetCustomPin(annotation as MKPointAnnotation);
//Get Value
c_annotation = annotation;
if (customPin == null)
{
throw new Exception("Custom pin not found");
}
annotationView = mapView.DequeueReusableAnnotation(customPin.Name);
if (annotationView == null)
{
annotationView = new CustomMKAnnotationView(annotation, customPin.Name);
annotationView.CalloutOffset = new CGPoint(0, 0);
((CustomMKAnnotationView)annotationView).Name = customPin.Name;
((CustomMKAnnotationView)annotationView).Url = customPin.Url;
((CustomMKAnnotationView)annotationView).Address = customPin.Address;
//Add First Line
((CustomMKAnnotationView)annotationView).AlertLevel = customPin.AlertLevel;
if (customPin.AlertLevel == 1)
{
annotationView.Image = UIImage.FromFile("green.png");
}
else if (customPin.AlertLevel == 2)
{
annotationView.Image = UIImage.FromFile("yellow.png");
}
else if (customPin.AlertLevel == 3)
{
annotationView.Image = UIImage.FromFile("orange.png");
}
else if (customPin.AlertLevel == 4)
{
annotationView.Image = UIImage.FromFile("red.png");
}
//Add Second Line
((CustomMKAnnotationView)annotationView).CodeNum = customPin.CodeNum;
((CustomMKAnnotationView)annotationView).MapCode = customPin.MapCode;
//Here I add the RequestUri for stations
string GenerateRequestUriStations(string endpoint)
{
string requestUri = endpoint;
requestUri += $"stations";
return requestUri;
}
//Here I need the loop from 0 to 16 every page and change the pin icons like above if statement
string GenerateRequestUri(string endpoint)
{
string requestUri = endpoint;
requestUri += $"?id=0";
return requestUri;
}
//This is the value who I need to compare result.WaterData.Ardaforecast but does not allow me to write result.WaterData.Ardaforecast and does not allow me to foreach here .. I don't know why ?
var reusult = _restServiceData.GetWaterDataForecast(GenerateRequestUriStations(Constants.EndPoint), GenerateRequestUri(Constants.EndPoint));
}
annotationView.CanShowCallout = true;
configureDetailView(annotationView);
return annotationView;
}
In the comments above the code I mean that when I write:
var reusult = _restServiceData.GetWaterDataForecast(GenerateRequestUriStations(Constants.EndPoint), GenerateRequestUri(Constants.EndPoint));
foreach (var item in IAsyncResult)
{
}
When I try to write result. automatic puts me IAsyncResult.. I don't know why.. ?
Can I get an example of how to loop all the pages and change colors on the markers ?
My GetDataFromAPI look like this:
public IEnumerable<AlertLevel> GetDataFromAPI(int mapCode)
{
var listAlert = new List<AlertLevel>();
var reusult = _restServiceData.GetWaterDataForecast(GenerateRequestUriStations(Constants.EndPoint), GenerateRequestUri(Constants.EndPoint, mapCode));
foreach (var item in reusult.WaterData.Ardaforecast[0].Items)
{
var currentData = new AlertLevel()
{
dateForecast = item.DateTimeForecast,
levelForecast = item.AlertLevelForecast
};
listAlert.Add(currentData);
}
return listAlert;

I want to post data to the database where I am fetching the data in a JSON format.
Here is the following JSON string:
"[{"cph_id":"67/123/7894","phone_no":"0000623019"},
{"cph_id":"69/213/1234","phone_no":"0000623019"}]"
I have also created the following classes:
public class RootObject
{
public List<dlregistrationdata> data { get; set; }
}
public class dlregistrationdata
{
public string cph_id[] { get; set; }
public string phone_no[] { get; set; }
}
I try to deserialize using the following command:
try
{
var obj = JsonConvert.DeserializeObject<List<dlregistrationdata>>(result);
var httpWebRequest = (HttpWebRequest)WebRequest.Create("http://172.61.25.30/CPRestApi/api/user/register");
httpWebRequest.ContentType = "application/json";
httpWebRequest.Method = "POST";
if (email != null)
{
using (var streamWriter = new StreamWriter(httpWebRequest.GetRequestStream()))
{
dynamic arr = new JObject();
for (int i = 0; i < obj.Count; i++)
{
arr.cph_id = obj[i].cph_id;
arr.user_name = email;
arr.user_phone_number = obj[i].phone_no;
arr.user_password = password;
arr.status = 1;
arr.name = name;
}
streamWriter.Write(arr);
}
}
var httpResponse = (HttpWebResponse)httpWebRequest.GetResponse();
if (httpResponse.StatusCode == System.Net.HttpStatusCode.Created)
{
using (var streamReader = new StreamReader(httpResponse.GetResponseStream()))
{
var result1 = streamReader.ReadToEnd();
}
return RedirectToLocal("Index");
}
}
catch (Exception ex)
{
Console.WriteLine(ex.Message);
ViewBag.ErrorMessage = "User Already Registered";
ModelState.AddModelError("", "User Already Registered");
return View(model);
}
But I am getting the error:
"converting value "67/123/7894" to type 'System.String[]'. Path '[0].cph_id', line 1, position 24"
Any help will be highly appreciated.
Thank You!
Changes made in model class:
public class dlregistrationdata
{
public string cph_id { get; set; }
public string phone_no { get; set; }
}
public class RequestRegistrationAPI {
public string user_name { get; set; }
public string user_password { get; set; }
public string user_phone_number { get; set; }
public string name { get; set; }
public int status { get; set; }
public string[] cph_id { get; set; }
}
Changes made in code:
using (var streamWriter = new StreamWriter(httpWebRequest.GetRequestStream()))
{
List<string> cphid = new List<string>();
string phone_no = "";
foreach (dlregistrationdata data in obj)
{
cphid.Add(data.cph_id);
phone_no = data.phone_no;
}
RequestRegistrationAPI request = new RequestRegistrationAPI();
request.user_name = email;
request.user_password = password;
request.user_phone_number = phone_no;
request.name = name;
request.cph_id = cphid.ToArray();
request.status = 1;
streamWriter.Write(JsonConvert.SerializeObject(request));
}
This works perfectly for me.
change classes to :
public class dlregistrationdata
{
public string cph_id { get; set; }
public string phone_no { get; set; }
}
now change code to :
var obj = JsonConvert.DeserializeObject<List<dlregistrationdata>>(result);
var httpWebRequest = (HttpWebRequest)WebRequest.Create("http://172.61.25.30/CPRestApi/api/user/register");
httpWebRequest.ContentType = "application/json";
httpWebRequest.Method = "POST";
if (email != null)
{
using (var streamWriter = new StreamWriter(httpWebRequest.GetRequestStream()))
{
dynamic arr = new JObject();
for (int i = 0; i < obj.Count; i++)
{
arr.cph_id = obj[i].cph_id;
arr.user_name = email;
arr.user_phone_number = obj[i].phone_no;
arr.user_password = password;
arr.status = 1;
arr.name = name;
}
streamWriter.Write(arr);
}
}
I have got a problem with undestanding powershell cmdlet.
Task is, to deserialize a xml file. I have got a folder with a lot of xml files, I would like to read in an filter certain information using the deserializiation method. My supervisor mentioned that I should use powershell cmdlet... but I haven't heard anything of it before. So what is the benefit? And how do I create such a cmdlet.

I'm very thankful for help!
I have a WPF application that calls an API and creates an System.Xml.Linq.XDocument using XDocument.Parse(string). I am running into a problem where an XmlException ("Root element is missing") is thrown when I try to do this, but my XML is completely valid. I tried syntax-checking it by calling the API in my browser and checking its syntax, calling the API in my application and Console.WriteLineing the response, and using various XML syntax validators (all of which returned no errors).
A sample XML response from the API is as follows:
<?xml version="1.0" encoding="UTF-8"?>
<response>
<event title="Event 1" id="75823347" icon="www.example.com/images/event1-icon.png" uri="www.example.com/rsvp/event1" mode="none" price="10.00" cover="www.example.com/event1-cover.png" enddate="2016-06-01 14:00:00" startdate="2016-06-01 12:00:00" address="1 Example St, Example City State 12345" location="Example Place" description="This is an event" shortdescription="This is an event" theme="auto" color="#FF000000"/>
</response>
This is my application's code:
public static WebRequest CreateRequest(string baseUrl, string httpMethod, Dictionary<string, string> requestValues) {
var requestItems = requestValues == null ? null : requestValues.Select(pair => string.Format("&{0}={1}", pair.Key, pair.Value));
var requestString = "";
if (requestItems != null)
foreach (var s in requestItems)
requestString += s;
var request = WebRequest.CreateHttp(baseUrl + CredentialRequestString + requestString);
request.Method = httpMethod.ToUpper();
request.ContentType = "application/x-www-form-urlencoded";
request.Credentials = CredentialCache.DefaultCredentials;
return request;
}
public static WebRequest CreateRequest(string apiEndpoint, string endpointParam, int apiVersion, string httpMethod, Dictionary<string, string> requestValues) {
return CreateRequest(string.Format("http://www.example.com/api/v{0}/{1}/{2}", apiVersion, apiEndpoint, endpointParam), httpMethod, requestValues);
}
public static async Task<string> GetResponseFromServer(WebRequest request) {
string s;
using (var response = await request.GetResponseAsync()) {
using (var responseStream = response.GetResponseStream()) {
using (var streamReader = new StreamReader(responseStream)) {
s = streamReader.ReadToEnd();
}
}
}
return s;
}
public static async Task<List<Event>> GetEvents() {
var response = await GetResponseFromServer(CreateRequest("events", "", 1, "GET", null));
Console.WriteLine(response); //validation
var data = XDocument.Parse(response).Root; //XmlException: Root element is mising
return new List<Event>(data.Elements("event").Select(e => Event.FromXml(e.Value)));
}
Why is this happening?

In form1 constructor i did:
Youtube_Video_Information.ytKey = "myapikey";
Youtube_Video_Information yvi = new Youtube_Video_Information();
yvi.YouTubeImport("ee-myvideoid");
The problem is that i'm getting error on:
Youtube_Video_Information.ytKey
Error 3 The left-hand side of an assignment must be a variable, property or indexer
How can i solve the error ?
How do i assign a value to a public const string variable?
You cannot. Const values cannot have a value assigned in runtime. If you need to be able to assign value in runtime, pass the value to a constructor call and make the member readonly.
class Youtube_Video_Information
{
public readonly string ytKey;
public Youtube_Video_Information(string ytKey)
{
this.ytKey = ytKey;
}
}
