Is it possible to calculate the size of a (complexed) object (with dataContract) that I send over WCF? What I need is to calculate the size on both the request and the response objects and I need to do this in a winform application.
Could I maybe serlize the objects and then get the total size?
You can manually serialise / deserialise the objects yourself. Here's a simple example of serialisation and obtaining the length.
[DataContract(Name = "Person", Namespace = "http://www.woo.com")]
class Person
{
[DataMember()]
public string Name;
[DataMember()]
public int Age;
}
calling code (in a console app)
Person p = new Person();
p.Name = "Sean Cocteau";
p.Age = 99;
DataContractSerializer ds = new DataContractSerializer(p.GetType());
using (System.IO.MemoryStream ms = new System.IO.MemoryStream())
{
ds.WriteObject(ms, p);
// Spit out
Console.WriteLine("Output: " + System.Text.Encoding.UTF8.GetString(ms.ToArray()));
Console.WriteLine("Message length: " + ms.Length.ToString());
}
Console.ReadKey();
In respect to performing this automatically, say on each WCF call may involve you having to create your own Custom Binding that adds this to the message.
I think a message interceptor will help, you can add this endpoint behavior to the endpoint and handle httpwebrequest/response.
For more information, google WCF Message Interceptor, you'll find lots of useful things.
Hope this will help.
You can use svctraceviewer to trace both the activity and the message and then you can see the actual message flowing over WCF. However it seems that this tool might not get you the total size.
This post might help.

I am trying to get the full contents of my modules From Zoho to our local Server. The deluge code does work as it returns to me the data which is being sent via the API. However, once it reaches the API, it is null. Any idea?
Below is the deluge code:
// Create a map that holds the values of the new contact that needs to be created
evaluation_info = Map();
evaluation_info.put("BulkData",zoho.crm.getRecords("Publishers"));
data = Map();
data.put(evaluation_info);
response = invokeurl
[
url :"https://zohoapi.xxxxx.com/publisher/publish"
type :POST
parameters:data
connection:"zohowebapi"
];
info data; (data returns all the data from publishers)
Here is my ASP.NET core restful API. It does ping it and create the file but the content of the file is null.
Route("[controller]")]
[ApiController]
public class PublisherController : ControllerBase
{
[HttpGet("[action]"), HttpPost("[action]")]
public void Publish(string data)
{
(it's already null when it comes here. why?)
string JSONresult = JsonConvert.SerializeObject(data);
string path = #"C:\storage\journalytics_evaluationsv2.json";
using (var file = new StreamWriter(path, true))
{
file.WriteLine(JSONresult.ToString());
file.Close();
}
}
}
}
What am I missing? Thank you
After contacting Zoho support, the solution he offered was to loop through the data in order to get all the contents from a module (if they are more than 200 records. With the solution provided, one doesn't really need the deluge code anymore as long as you have the ZOHO api set to your account in code. This was my final solution. This solution is not scalable at all. It's best to work with the BULK CSV.
// Our own ZohoAPI which lets us connect and authenticate etc. Yours may look slightly different
ZohoApi zohoApi = new ZohoApi();
zohoApi.Initialize();
ZCRMRestClient restClient = ZCRMRestClient.GetInstance();
var allMedicalJournals = new List<ZCRMRecord>();
for (int i = 1; i <= 30; i++)
{
List<ZCRMRecord> accountAccessRecords2 =
restClient.GetModuleInstance("Journals").SearchByCriteria("Tag:equals:MedicalSet", i, 200).BulkData.ToList();
foreach (var newData in accountAccessRecords2)
allMedicalJournals.Add(newData);
}

I'm trying to perform a real-time Predict operation, and to verify the basic setup works, I first perform a GetMLModel() which works and returns the endpoint (Somewhere in the documentation is was mentioned to use that result as the service endpoint, but it's the same that is listed in the console). Is has status "READY", so far so good.
The exception occurs below on the line below "Prediction P = RTP.Predict(Data)". Data contains a Dictionary with all the prediction values.
Error: Error making request with Error Code UnknownOperationException and Http Status Code BadRequest. No further error information was returned by the service.
public static APIResult GetRealTimePrediction(Dictionary<string, string> Data, string PayloadJSON = null) {
AmazonMachineLearningConfig MLConfig = new AmazonMachineLearningConfig();
MLConfig.RegionEndpoint = Amazon.RegionEndpoint.USEast1;
MLConfig.Validate();
AmazonMachineLearningClient MLClient = new AmazonMachineLearningClient("xxx", "xxx", MLConfig);
GetMLModelResponse MLMOdelResp = MLClient.GetMLModel("xxx"); // <-- WORKS
MLConfig.ServiceURL = MLMOdelResp.EndpointInfo.EndpointUrl;
Console.WriteLine(MLConfig.ServiceURL);
MLConfig.Validate();
Amazon.MachineLearning.Util.RealtimePredictor RTP = new Amazon.MachineLearning.Util.RealtimePredictor(MLClient, "xxx");
Prediction P = RTP.Predict(Data); // <----------------EXCEPTION HERE
}
(Obviously replace xxx with relevant values) :)
It turns out that this line:
MLConfig.ServiceURL = MLMOdelResp.EndpointInfo.EndpointUrl;
cases the MLConfig.RegionEndpoint to be reset. Even though the documentation indicates the RegionEndpoint can be determined from the ServiceURL (I'm pretty sure I read that), the RegionEndpoint needs to be set again before the RTP.Predict(Data) call.
Once I figured that out, I was able to reduce the code to just this, in case anyone else needs help. I guess adding too much information to the Configuration is NOT a good thing, as the AWS. NET library seems to figure all this out on its own.
public static APIResult GetRealTimePrediction(Dictionary<string, string> Data, string PayloadJSON = null) {
AmazonMachineLearningConfig MLConfig = new AmazonMachineLearningConfig();
MLConfig.RegionEndpoint = Amazon.RegionEndpoint.USEast1;
MLConfig.Validate(); // Just in case, not really needed
AmazonMachineLearningClient MLClient = new AmazonMachineLearningClient("xxx", "xxx", MLConfig);
Amazon.MachineLearning.Util.RealtimePredictor RTP = new Amazon.MachineLearning.Util.RealtimePredictor(MLClient, "xxx");
Prediction P = RTP.Predict(Data);
}
I am attempting to allow users to add events from an online calendar to the calendars on their device using DDay.iCal. This seems to work fine on iOS and on desktop platforms, but I am running into a snag with Android devices. I run into this message:
Is there a better way to serve this event that would keep that from happening?
public ActionResult ICS(int id)
{
// Get event from Database
var heEvent = HEEvent.GetEventDetails(id);
// Create iCal object
var iCal = new iCalendar();
iCal.Method = "PUBLISH";
// Create iCal Event
var icalEvent = iCal.Create<DDay.iCal.Event>();
icalEvent.Summary = heEvent.Name;
icalEvent.Start = new iCalDateTime(heEvent.TimeBegin.Year, heEvent.TimeBegin.Month, heEvent.TimeBegin.Day, heEvent.TimeBegin.Hour, heEvent.TimeBegin.Minute, 00);
TimeSpan calculatedEventDuration = heEvent.DateEnd.Subtract(heEvent.TimeBegin);
if (calculatedEventDuration.Hours > 1) { icalEvent.Duration = calculatedEventDuration; }
else { icalEvent.Duration = TimeSpan.FromHours(1); } // default to 1 hour if event time is less
icalEvent.Location = heEvent.Location;
// Create a serialization context and serializer factory.
// These will be used to build the serializer for our object.
ISerializationContext ctx = new SerializationContext();
ISerializerFactory factory = new DDay.iCal.Serialization.iCalendar.SerializerFactory();
// Get a serializer for our object
IStringSerializer serializer = factory.Build(iCal.GetType(), ctx) as IStringSerializer;
string output = serializer.SerializeToString(iCal);
var contentType = "text/calendar";
var bytes = Encoding.UTF8.GetBytes(output);
return File(bytes, contentType, String.Format(#"{0}.ics", heEvent.Name.Replace(" ", "_")));
}
Your error, you don't need me to tell you, has nothing to do with Ical. It's entirely between you, your phone, and your technology budget. (Buy an SD card !)
As regards serving Icalendars, you often hear them called feeds, but clients subscribed to an Icalendar poll the calendar url regularly, requesting the whole calendar each time. To avoid lots of needless processing, you will want to persist the calendar(s) somehow so that changes propagate without regenerating the same calendar thousands of times. For this, I suggest the file system and good use of HTTP caching headers. When your calendar is modified, write it as a static file in a web facing directory. Perhaps you're already doing this. Then set sensible caching headers on your webserver and away you go.
I have a sample program from Aforge library. It uses a kind of logging system (I assume it is like a StringBuilder or something...).
In the samples, here and there I see something like:
IImageProcessingLog _log = new ImageProcessingLog();
//some code
_log.AddMessage("Image size: " + _bitmap.Width + " x " + _bitmap.Height);
//more codes and usage of `_log`
Clearly this is some sort of string. Later I want to dump all this data into a TextBox. I tried to do _log.ToString() but it just returns the object name.
Any idea how can I use this log feature?
Thanks
The ImageProcessingLog class has a property called Messages.
Messages is of type List<string>. So, to get all logged messages
simply iterate the elements of the messages list.
TextBox tbMessages = ...;
ImageProcessingLog log = new ImageProcessingLog();
log.AddMessage(...);
foreach(string msg in log.Messages)
{
tbMessages.Text += msg;
}
Unfortunately the IImageProcessingLog interface does not have such a property.
A possible workaround would be to create an adapter class/interface which wraps the
ImageProcessingLog class.
I have been trying to create an application to go through our database at a set interval and update/add any new items to 3DCarts database. Their code example uses soap in an xml file to send 1 request per call. So I need to to be able to generate the xml I need with the items information on the fly before sending it. I have done hardly anything with XML files like this and cannot figure out how to create the chunk of code I need and send it. One method that has been suggested is create a file but still executing has been a problem and would be very inefficient for a large number of items. Here is what I have so far
sqlStatement = "SELECT * FROM products WHERE name = '" + Convert.ToString(reader.GetValue(0)) + "'";
ServiceReferenceCart.cartAPIAdvancedSoapClient bcsClient = new ServiceReferenceCart.cartAPIAdvancedSoapClient();
ServiceReferenceCart.runQueryResponse bcsResponse = new ServiceReferenceCart.runQueryResponse();
bcsClient.runQuery(storeUrl, userKey, sqlStatement, callBackURL);
string result = Convert.ToString(bcsResponse);
listBox1.Items.Add(result);
EDIT: Changed from sample code block to current code block as I got a service reference setup finally. They provide no details though for using the functions in the reference. With this bcsResponse is just a blank, when I try adding .Body I have the same result but when I add .runQuery to the .Body I get a "Object reference not set to an instance of an object." error. As I have said I have not messed with service references before.
I hope I have explained well enough I just really have not worked with this kind of stuff before and it has become extremely frustrating.
Thank you in advance for any assistance.
I actually ended up figuring this out after playing around with it. Here is what I did to get the reference to work. This may have been easy for anyone who have used the references before but I have not and have decided to post this in case anyone else has this problem. The SQL can be SELECT, ADD, UPDATE and DELETE statements this was to see if the sku was listed before updating/adding.
//Will be using these multiple times so a variable makes more sense
// DO NOT include http:// in the url, also id is not shown in their
//database layout pdf they will give but it is the sku/product number
string sqlStatement = "SELECT id FROM products WHERE id = '" + Convert.ToString(reader.GetValue(0)) + "')))";
string userKey = "YourKeyHere";
string storeUrl = "YourStoresURLHere";
// Setting up instances from the 3DCart API
cartAPIAdvancedSoapClient bcsClient = new cartAPIAdvancedSoapClient();
runQueryRequest bcsRequest = new runQueryRequest();
runQueryResponse bcsResponse = new runQueryResponse();
runQueryResponseBody bcsRespBod = new runQueryResponseBody();
runQueryRequestBody bcsReqBod = new runQueryRequestBody();
//assigning required variables to the requests body
bcsReqBod.storeUrl = storeUrl;
bcsReqBod.sqlStatement = sqlStatement;
bcsReqBod.userKey = userKey;
//assigning the body to the request
bcsRequest.Body = bcsReqBod;
//Setting the response body to be the result
bcsRespBod.runQueryResult = bcsClient.runQuery(bcsReqBod.storeUrl, bcsReqBod.userKey, bcsReqBod.sqlStatement, bcsReqBod.callBackURL );
bcsResponse.Body = bcsRespBod;
//adding the result to a string
string result = bcsResponse.Body.runQueryResult.Value;
//displaying the string, this for me was more of a test
listBox1.Items.Add(result);
You will also need to activate the Advanced API on your shop as you may notice there is no actual option as the pdf's say, you need to go to their store and purchase(its free) and wait for them to activate it. This took about 2 hrs for us.
