Amazon MWS receiving MalformedInput on GetMyFeesEstimate

I'm trying to access Amazon MWS API from my .Net application, using Products API Section Client Library - C# (https://developer.amazonservices.com/doc/products/products/v20111001/cSharp.html/138-8219342-3408216)
Everything works fine, except for GetMyFeesEstimate calls.
I use this method from example:
public GetMyFeesEstimateResponse InvokeGetMyFeesEstimate()
{
// Create a request.
GetMyFeesEstimateRequest request = new GetMyFeesEstimateRequest();
string sellerId = "example";
request.SellerId = sellerId;
string mwsAuthToken = "example";
request.MWSAuthToken = mwsAuthToken;
FeesEstimateRequestList feesEstimateRequestList = new FeesEstimateRequestList();
request.FeesEstimateRequestList = feesEstimateRequestList;
return this.client.GetMyFeesEstimate(request);
}
And I add item to FeesEstimateRequestList like this:
feesEstimateRequestList.FeesEstimateRequest.Add(new FeesEstimateRequest
{
MarketplaceId = marketplaceId,
IdType = "ASIN",
IdValue = "B0078LENZC",
PriceToEstimateFees = new PriceToEstimateFees { ListingPrice = new MoneyType { Amount = 30.49M, CurrencyCode = "GBP" }, Shipping = new MoneyType { Amount = 3.5M, CurrencyCode = "GBP" }, Points = new Points { PointsNumber = 0 } },
Identifier = "request_" + Guid.NewGuid().ToString(),
IsAmazonFulfilled = false
});
But constantly get MalformedInput error with no message describing what is wrong:
<ErrorResponse
xmlns="http://mws.amazonservices.com/schema/Products/2011-10-01">
<Error>
<Type>Sender</Type>
<Code>MalformedInput</Code>
</Error>
<RequestId>f79b9147-90d7-4ea2-b51c-d6c37c6a1bd0</RequestId>
</ErrorResponse>
Have someone any ideas how to make it work?

I have found solution:
Due to my OS regional settings, decimal separator in price had being set to comma, instead of dot when converting parameters to string.
I have to modify method putValue of MwsAQCall class like this:
private void putValue(object value)
{
if (value==null)
{
return;
}
if (value is IMwsObject)
{
parameterPrefix.Append('.');
(value as IMwsObject).WriteFragmentTo(this);
return;
}
string name = parameterPrefix.ToString();
if (value is DateTime)
{
parameters.Add(name, MwsUtil.GetFormattedTimestamp((DateTime)value));
return;
}
string valueStr = value.ToString();
if (value is decimal)
{
valueStr = valueStr.Replace(",", ".");
}
if (valueStr==null || valueStr.Length==0)
{
return;
}
if (value is bool)
{
valueStr = valueStr.ToLower();
}
parameters.Add(name, valueStr);
}

Open Outlook 2013 New Appointment window at Client side with Microsoft.Office.Interop.Outlook C#

I am trying to open Outlook 2013 New Appointment window at Client side with ASP.Net c# application. my code is working fine its a simple button. when i click the button from client machine this application open the outlook window on server/host machine but not on Client Machine.
what can i use to open Outlook Appointment window on client machine by using ASP.Net C#.
I am using following code:
private void OpenOutlookAppt() {
Microsoft.Office.Interop.Outlook.Application app = null;
Microsoft.Office.Interop.Outlook.AppointmentItem appt = null;
app = new Microsoft.Office.Interop.Outlook.Application();
appt = (Microsoft.Office.Interop.Outlook.AppointmentItem)app.CreateItem(Microsoft.Office.Interop.Outlook.OlItemType.olAppointmentItem);
appt.Subject = "Customer Review";
appt.MeetingStatus = Outlook.OlMeetingStatus.olMeeting;
appt.Location = "36/2021";
appt.Start = Convert.ToDateTime("3/30/2016 01:30:00 PM");
appt.End = Convert.ToDateTime("3/30/2016 02:30:00 PM");
Outlook.Recipient recipRequired =
appt.Recipients.Add("abc#domain.com");
recipRequired.Type =
(int)Outlook.OlMeetingRecipientType.olRequired;
Outlook.Recipient recipOptional =
appt.Recipients.Add("abc#domain.com");
recipOptional.Type =
(int)Outlook.OlMeetingRecipientType.olOptional;
Outlook.Recipient recipConf =
appt.Recipients.Add("Conf Room 36/2021 (14) AV");
recipConf.Type =
(int)Outlook.OlMeetingRecipientType.olResource;
appt.Recipients.ResolveAll();
appt.Display(true); }
Thanks

Your code runs on the server under IIS, so of course you end up using Outlook on the server machine. And Outlook cannot be used in a service (such as IIS).
Your options are:
Client side Java Script. IE only. Your site must be trusted to be able to create COM objects ("Outlook.Applicatuion").
Create an iCal (ICS) file on the server. When the end user opens it, saving it will create an appointment in Outlook.

I think the best way to achieve this is by generating an ICS file on the server for the web user to download and open.
The ICS file format is quite simple:
BEGIN:VCALENDAR
VERSION:2.0
BEGIN:VEVENT
STATUS:TENTATIVE
DTSTART:20160330T013000Z
DTEND:20160330T023000Z
SUMMARY;ENCODING=QUOTED-PRINTABLE:Customer Review
LOCATION;ENCODING=QUOTED-PRINTABLE:Conf Room 36/2021 (14) AV
DESCRIPTION;ENCODING=QUOTED-PRINTABLE:Customer Review Meeting
END:VEVENT
END:VCALENDAR

Handle duplicate records when doing a EF SaveChanges

I have an web application where I parse a csv file that can have over 200k records in it. I parse each line for information, verify that the key does not exist in the database and then add it to the context. When the count reaches 10,000 records it calls SaveChanges routine. The problem is that there can be duplicates in the context and it errors out. This is running on a Azure VM communicating to an Azure SQL server.
Two questions, how do I handle the duplicate issue and is there any way I can improve the speed as it takes several hours to run?
using (LoanFileEntities db = new LoanFileEntities())
{
db.Configuration.AutoDetectChangesEnabled = false; // 1. this is a huge time saver
db.Configuration.ValidateOnSaveEnabled = false; // 2. this can also save time
while (parser.Read())
{
counter++;
int loan_code = 0;
string loan_code_string = parser["LoanId"];
string dateToParse = parser["PullDate"].Trim();
DateTime date_pulled;
try
{
date_pulled = DateTime.Parse(dateToParse, CultureInfo.InvariantCulture);
}
catch (Exception)
{
throw new Exception("No Pull Date for line " + counter);
}
string originationdate = parser["OriginationDate"].Trim();
DateTime date_originated;
try
{
date_originated = DateTime.Parse(originationdate, CultureInfo.InvariantCulture);
}
catch (Exception)
{
throw new Exception("No Origination Date for line " + counter);
}
dateToParse = parser["DueDate"].Trim();
DateTime date_due;
try
{
date_due = DateTime.Parse(dateToParse, CultureInfo.InvariantCulture);
}
catch (Exception)
{
throw new Exception("No Due Date for line " + counter);
}
string region = parser["Region"].Trim();
string source = parser["Channel"].Trim();
string password = parser["FilePass"].Trim();
decimal principalAmt = Convert.ToDecimal(parser["Principal"].Trim());
decimal totalDue = Convert.ToDecimal(parser["TotalDue"].Trim());
string vitaLoanId = parser["VitaLoanId"];
var toAdd =
db.dfc_LoanRecords.Any(
x => x.loan_code_string == loan_code_string);
if (!toAdd)
{
dfc_LoanRecords loan = new dfc_LoanRecords();
loan.loan_code = loan_code;
loan.loan_code_string = loan_code_string;
loan.loan_principal_amt = principalAmt;
loan.loan_due_date = date_due;
loan.date_pulled = date_pulled;
loan.date_originated = date_originated;
loan.region = region;
loan.source = source;
loan.password = password;
loan.loan_amt_due = totalDue;
loan.vitaLoanId = vitaLoanId;
loan.load_file = fileName;
loan.load_date = DateTime.Now;
switch (loan.region)
{
case "UK":
if (location.Equals("UK"))
{
//db.dfc_LoanRecords.Add(loan);
if (loan.source == "Online")
{
counter_new_uk_online++;
}
else
{
counter_new_uk_retail++;
}
}
break;
case "US":
if (location.Equals("US"))
{
db.dfc_LoanRecords.Add(loan);
if (loan.source == "Online")
{
counter_new_us_online++;
}
else
{
counter_new_us_retail++;
}
}
break;
case "Canada":
if (location.Equals("US"))
{
db.dfc_LoanRecords.Add(loan);
if (loan.source == "Online")
{
counter_new_cn_online++;
}
else
{
counter_new_cn_retail++;
}
}
break;
}
// delay save to speed up load. 3. also saves transactional time
if (counter % 10000 == 0)
{
db.SaveChanges();
}
}
} // end of parser read
db.SaveChanges();
}
}
}

I would suggest removing duplicates in the code before sending it over to .SaveChanges().
Instead of going into detail about duplicate removal, I've put together this list of links to existing questions and answers on StackOverflow that may help:
Delete duplicates using Lambda
Using DISTINCT on a subquery to remove duplicates in Entity Framework
Using LINQ to find / delete duplicates
Hope that helps!

Date returning from c# web method - /Date(xxxxxxx)/

I am using jquery ajax to request a list of objects from a database via a c# web method:
[WebMethod]
public static List<SessionQueue> GetActiveIssues()
{
try
{
return MyContext.SessionQueues.Where(x => !x.Resolved).OrderBy(d => d.SubmittedTime).ToList();
}
catch (Exception ex)
{
throw new Exception(ex.ToString()); // catch in jquery
}
}
Each SessionQueue object has a property:
public System.DateTime SubmittedTime
When I receive the SubmittedTime in jquery, the date looks like this:
/Date(1445975227197)/
How do I parse this to a valid date string? e.e mm/dd/yy xx:xx am
I have tried:
function formatLongDate(date) {
var nd = Date.parse(date);
var dt = new Date(nd);
var dtStr = $.datepicker.formatDate("mm/dd/yy", dt) + ' ' + getTime(date)
return dtStr;
}
but /Date(1445975227197)/ is not a valid date ticks

Try using String.prototype.match() , Array.protottpe.map()
new Date("/Date(1445975227197)/".match(/\d+/).map(Number)[0])

MVC Converts dates to the number of milliseconds from Jan 1, 1970. The simplest way to convert it to a javascript date is to do the following
var convertedDate = new Date(parseInt(SubmittedTime.substr(6)));

Calendar calendar = Calendar.getInstance();
//timestamp is where you're getting the 1445975227197
calendar.setTimeInMillis(timeStamp);
int mYear = calendar.get(Calendar.YEAR);
int mMonth = calendar.get(Calendar.MONTH);
int mDay = calendar.get(Calendar.DAY_OF_MONTH);

C# Can't modify Error.Message String

I have to display a validation message when a user selects a date outside the allowed range. The is the code i have to work with:
public ActionResult QuickEdit(int pk, string name, string value)
{
var freeOfChargeTime = Db.FreeOfChargeTime.Find(pk);
freeOfChargeTime.ProjectExtension = freeOfChargeTime.ProjectExtension ?? Db.ProjectExtensions.Find(freeOfChargeTime.ProjectExtensionId);
if ((name == "StartDate" && DateTime.Parse(value) > freeOfChargeTime.EndDate) || (name == "EndDate" && DateTime.Parse(value) < freeOfChargeTime.StartDate))
{
ModelState.AddModelError("StartDate", "the end date must be after the start date");
}
if (name == "NumberOfDays" && double.Parse(value) <= 0)
{
ModelState.AddModelError("NumberOfDays", "Number of days must be > 0");
}
if (name == "StartDate" && DateTime.Parse(value) < freeOfChargeTime.ProjectExtension.StartDate)
{
ModelState.AddModelError("StartDate", "the free of charge period start date must be after the project extension start date");
}
if (freeOfChargeTime.ProjectExtension is IPextWithEndDate)
{
var poWithEndDate = (IPextWithEndDate)freeOfChargeTime.ProjectExtension;
if (name == "EndDate" && DateTime.Parse(value) > poWithEndDate.EndDate)
{
ModelState.AddModelError("EndDate", "the free of charge period end date must be before the project extension end date");
}
}
if (freeOfChargeTime.ProjectExtension.StatusId == ProjectExtensionStatus.Cancelled ||
freeOfChargeTime.ProjectExtension.StatusId == ProjectExtensionStatus.Disabled)
{
ModelState.AddModelError("Status", "the project extension is cancelled or disabled");
}
if (ModelState.IsValid) return XEditableUpdate(Db.FreeOfChargeTime, pk, name, value);
Response.StatusCode = 400;
var error = new Error { Message = "Error: " + ModelState.Errors() };
return Json(error.Message, JsonRequestBehavior.AllowGet);
}
This displays "Error: the free of charge period start date must be after the project extension start date\n"
I have tried:
#*#1*#
error.Message = error.Message.Split('\\').First();
#*#2*#
error.Message = error.Message.Replace("\\n", " ");
#*#3*#
string validationMessage = error.Message.Split('\\').First();
#*#4*#
string validationMessage = error.Message.Replace("\\n", " ");
#*#5*#
string validationMessage = error.Message;
validationMessage = validationMessage.Split('\\').First();
#*#6*#
string validationMessage = error.Message;
validationMessage = validationMessage.Replace("\\n", " ");
I still get the same result. Is there any way to get rid of the "\n", or work around the problem?

validationMessage.Replace("\r\n", string.Empty).Replace("\n", string.Empty).Replace("\r", string.Empty);
Use this code.
