Web service constructor

Mon, 14 Nov 2005 17:33:07 Z

I defined a class (MyWebService) that inherits System.Web.Services.WebService class. I would like to pass a username and password when initialize the web service so the user that try to access the web service can be authenticated against the database. However, when I try to use the web service in the client project, it seems I can only use the default non-parameters constructor.

Is it impossible to to initialize a web service using the non-default constructor?

JSON Serialization instead of XML Serialization

Thu, 19 Nov 2009 14:19:54 Z

Hello, I need to write a simple Web Service that returns data with JSON Serialization instead of XML (SOAP).

Can anyone post a sample solution to achieve this goal?

Best regards

WSE is Obsolete - Use Only If Necessary

Tue, 02 Jun 2009 00:20:25 Z

To my fellow Web Service Developers:

I have repeatedly encountered developers who learn about WSE (Web Service Enhancements) through Google or some other search engine. In many cases, they were not searching for WSE, but instead were searching for "web service security" or "web service outside of IIS". Because the search turned up a WSE article, some of these developers are starting off with WSE when they don't need to.

I want to make clear what I so frequently have to repeat: WSE is obsolete. It has been replaced by WCF (Windows Communication Framework). WSE is not supported by Visual Studio 2008 or above. This should give you an idea about how Microsoft thinks about WSE. If your project is at all important, and if you expect it to last more than a few months, then you will not be doing yourself any favors by depending on this obsolete software.

WCF is supported by .NET 3.0 and above, though your best option would be .NET 3.5 SP1. Some organizations will not upgrade to .NET 3.5 because they are concerned about the impact on their existing .NET 2.0 applications. There is little need for concern: .NET 3.5 SP1 consists of .NET 2.0 SP2 and some additional assemblies that are not used by your existing .NET 2.0 applications. It will also not change your IIS script mappings the same way the upgrading from .NET 1.1 to .NET 2.0 did.

Obviously, if you are working on an existing WSE application, then you should upgrade to WSE when you get a chance, but should continue to maintain your application until you upgrade. A small number of you will have no choice but to use WSE for new applications; perhaps you must still support Windows 2000. If you have no choice but to use WSE, then feel free to post your WSE questions in this forum. I have found that WSE questions are answered more quickly if you put "WSE" into the subject of the question.

Good Luck to All,

Hi,

I'm working on project of integration and I have to generate web services interface everytime that the web services exposed are updated. This request is made to create mock of this web services.

Now I'm using the wsdl command to create this web services interface, but I have to operate manually for each web services everytime that the exposed web sevices are updated. Does exist any tool to made this operation as automatic batch process?

Sorry for bad english.

Thank you very much in advance.

XML custom serialization in asmx web service

Tue, 10 Nov 2009 12:46:52 Z

Hi, I try used custom XML serialization on my own class with IXmlSerializable, and also use xml scheme.

public class Service : System.Web.Services.WebService
{
    [XmlSchemaProvider("GetSchemaDocument")]
    public class EmployeeDetails3 : IXmlSerializable
    {

        public int employeeID;

        public string firstName;

        public string lastName;

        private string phoneNumber;

        const string ns = "";

        public static XmlQualifiedName GetSchemaDocument(XmlSchemaSet xs)
        {

            string schemaPath =
             "E:\\Project\\CustomSerializationInASPNET.WebService\\App_Data\\EmployeeDetails3.xsd";

            XmlSerializer schemaSerializer = new XmlSerializer(typeof(XmlSchema));
            XmlSchema s = (XmlSchema)schemaSerializer.Deserialize(new XmlTextReader(schemaPath), null);
            xs.XmlResolver = new XmlUrlResolver();
            xs.Add(s);
            return new XmlQualifiedName("EmployeeDetails3", ns);
        }

        void IXmlSerializable.WriteXml(XmlWriter w)
        {

            w.WriteStartElement("Employee", ns);

            w.WriteStartElement("Name", ns);

            w.WriteElementString("First", ns, firstName);

            w.WriteElementString("Last", ns, lastName);

            w.WriteEndElement();

            w.WriteElementString("ID", ns, employeeID.ToString());

            w.WriteElementString("Phone", ns, phoneNumber.ToString());

            w.WriteEndElement();

        }


        System.Xml.Schema.XmlSchema IXmlSerializable.GetSchema()
        {

            return null;

        }

        public EmployeeDetails3()
        { }

        public EmployeeDetails3(int employeeID, string firstName, string lastName, string phoneNumber)
        {

            this.employeeID = employeeID;

            this.firstName = firstName;

            this.lastName = lastName;

            this.phoneNumber = phoneNumber;
        }

    }


    [WebMethod]
    public EmployeeDetails3[] GetEmployee3()
    {
        EmployeeDetails3[] employeeObj = new EmployeeDetails3[3];

        employeeObj[0] = new EmployeeDetails3(1, "X", "X", "X");
        employeeObj[1] = new EmployeeDetails3(2, "Y", "Y", "Y");
        employeeObj[2] = new EmployeeDetails3(3, "Z", "Z", "Z");

        return employeeObj;
    }
}

Xml scheme for my own object is :

<?xml version="1.0" encoding="utf-8"?>
<xs:schema elementFormDefault="qualified" xmlns:xs="http://www.w3.org/2001/XMLSchema">
  <xs:element name="EmployeeDetails3" nillable="true" type="EmployeeDetails3" />
  <xs:complexType name="EmployeeDetails3">
    <xs:sequence>
      <xs:element minOccurs="0" maxOccurs="1" name="First" type="xs:string" />
      <xs:element minOccurs="0" maxOccurs="1" name="Last" type="xs:string" />
      <xs:element minOccurs="1" maxOccurs="1" name="ID" type="xs:int" />
      <xs:element minOccurs="0" maxOccurs="1" name="Phone" type="xs:string" />
    </xs:sequence>
  </xs:complexType>
</xs:schema>

I think the xml scheme is wrong, I am beginner. What is wrong with my xml scheme ?

If I try compile my project and test on asp.net development server it finish with this warnning:

T*his web service does not conform to WS-I Basic Profile v1.1.

Please examine each of the normative statement violations below. Follow the recommendations to remedy it, or add setting to the config section to turn off BP 1.1 conformance warnings for the entire vroot.

To turn off BP 1.1 conformance warnings for the entire vroot remove the 'BP1.1' value from the section of the configuration file of your application:

R2105: All xsd:schema elements contained in a wsdl:types element of a DESCRIPTION MUST have a targetNamespace attribute with a valid and non-null value, UNLESS the xsd:schema element has xsd:import and/or xsd:annotation as its only child element(s). - schema from service description with targetNamespace='http://tempuri.org/'.

Recommendation: Please examine your schema definitions and add explicit targetNamespace attribute. Requiring a targetNamespace on all xsd:schema elements that are children of wsdl:types is a good practice, places a minimal burden on authors of WSDL documents, and avoids the cases that are not as clearly defined as they might be.*

Newbie, trying to add Google Maps to my site

Sun, 15 Nov 2009 18:04:18 Z

I downloaded the sample code from here:

I’m not too sure if the order of the code matters much in the web.config area.

Can someone please tell me what I am doing wrong?

Thanks!

How can I open a library's app.config from a web service?

Fri, 09 Oct 2009 02:20:16 Z

I have three projects under one solution. The first project is a class library that contains all database handling. The second project is a WebService that performs the business logic and acts as the middle man between the UI and the database handling library. The third project is a WinForms project that consists of the users UI.

My class library contains an app.config with the various settings pertaining only to itself (connection strings, default values, etc). To read from this configuration I was originally using ConfigurationManager. However, I quickly found out the ConfigurationManager used the executing application's configuration and not the library's configuration. To use the library's configuration I used (placed in a method inside the library)

ConfigurationManager.OpenExeConfiguration(Assembly.GetExecutingAssembly().Location);

This worked fine when I called the library directly from the UI project after I added the library's app.config as a linked existing item and gave it a build action of content. I then moved all calls to the library from the UI to the WebService and added the library's app.config in the same manner as I did for the UI. This however, is not allowing me to use the library's app.config. When calling the library's method from the WebService, the above line of code is openning an unknown configuration file. The code

Assembly.GetExecutingAssembly().Location

shows that the dll is always copied to "<User>\AppData\Local\Temp\Temporary ASP.NET Files\root\fbe2780f\77f4c55e\assembly\dl3\c8e6491c\79da3d9d_8248ca01\<Library>". The library's app.config is not copied to this location and is then not opened (though a config is openned because OpenExeConfiguration doesn't return null.)

How can I access the library's app.config from a method contained within the library which is called from the web service?

WSE 3.0 Quickstart DOA with Visual Studio 2008 and .NET 3.5

Wed, 18 Nov 2009 21:42:41 Z

I installed Visual Studio 2008 and WSE 3 and .NET 3.5 and am attempting unsuccessfully to run the BinaryDataMTOM quick start example. I get a "Conversion Report" that says that the .csproj file was converted. I then get 6 build errors. Here is the first.

Message 1 Could not find schema information for the element 'http://schemas.microsoft.com/.NetConfiguration/v2.0:configuration'. C:\Program Files\Microsoft WSE\v3.0\Samples\CS\QuickStart\Basic\BinaryDataMTOM\BinaryDataMTOMService\web.config 10 2 C:\...\BinaryDataMTOMService\

It looks like MS took down a file from the corporate web site. Odd. I thought disk space was cheap.

My task is to come up with a textbook correct test web client to show .NET users how to use our server. I'm new to .NET and was depending on having working samples, and not just as a time saver. I'm not qualified to judge if some random internet advice is correct or not, even if what I do might appear to work at first.

Is there an actual working WSE download? Could someone from the WSE team please post an updated web.config file?

Autocad file printing

Trying to Connect my calendar to a SQL Server DB

Sun, 15 Nov 2009 18:08:07 Z

I am trying to link my calendar to a SQL Server DB. I’m following the example here:
http://www.codeproject.com/KB/webforms/MellDataCalendar.aspx

On that site, though, they link to an Access DB on the desktop. I’m pointing to a SQL Server DB on, well my desktop for now, but soon a server. My question is, how do I set up to connection to the SQL Server DB?

In the example from the site above, it is done like this:
            dim con as OleDbConnection = new OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:\Inetpub\wwwroot\DataCalendar\calendar.mdb")

Here is my code; I am trying to point to my SQL Server like this:
<% @Register Namespace="DataControls" Assembly="DataCalendar" TagPrefix="dc" %>

<% @Import Namespace="System.Data" %>
<% @Import Namespace="System.Data.OleDb" %>

<script language="vb" runat="server">

            dim cmd as OleDbCommand = new OleDbCommand()
            cmd.Connection = con
            'cmd.CommandText = "Select * From EventInfo"

Again, when I set up an Access DB on my desktop and point to that, the code works perfect. When I set up my SQL Server, and point to that, NOTHING WORKS. Any idea on what I can do to make this work on my site.

\r replaced in the deserialised xml

Thu, 12 Nov 2009 19:59:18 Z

I am reading a string with carriage returns and new lines into a string.

This string is later added to a xml, serialised, written to the db.

And When I read the string again from db, deserialise it to the object,I see that \rs are missing.

How can I preserver the \r?

Thanks

Partial deserialize

Tue, 17 Nov 2009 15:41:02 Z

Hello,

I haven't done much XML serialization/deserialization, but I think it's the best route for what I'm trying to do now. I created an XSD file and generated a class using the xsd command. It works fine when I load my entire xml file. What I don't know how to do, however, is a partial load. I need to load a "base" file, but then I need to load overrides/overwrites that is only a partial file. For example, let's say I have this:

<document>

	  <title>Title1</title>

	  ... a bunch of other stuff...

</document>

The next call will only contain a subset of the original, but could have different values.

<document>

	  <title>A new title</title>

</document>

I need to keep all of the other stuff and only overwrite the title. Could someone point me in the right direction? I'm assuming I need to override the deserialization method?

Thanks for any help, I really appreciate it.

Thanks,
Nick

cycling graph xml serialization

Tue, 17 Nov 2009 10:35:35 Z

Hi
I'm developing a java web service which should be consumed by .NET client. Generally, it shouldn't be any problem, this technology is quite mature this days.
However, there is problem with some particular data type. On the object level, I have a cycling graph reference. Obviously this can't be serializaed as a plain XML document. The most streightforwad approach is xsd:ID/xsd:IDREF usage, which handles such case, for example:
<xs:complexType name="a">
    <xs:sequence>
      <xs:element name="id" type="xs:ID" minOccurs="0"/>
      <xs:element name="myB" type="xs:IDREF" minOccurs="0"/>
      <xs:element name="someAfield" type="xs:string" minOccurs="0"/>
    </xs:sequence>
</xs:complexType>

<xs:complexType name="b">
    <xs:sequence>
      <xs:element name="id" type="xs:ID" minOccurs="0"/>
      <xs:element name="myA" type="xs:IDREF" minOccurs="0"/>
      <xs:element name="someBfield" type="xs:string" minOccurs="0"/>
    </xs:sequence>
</xs:complexType>

The problem with IDREF is that on the design time the reference is not strictly typed. I.e., if such schema is imported to .NET, the type of field, specified by IDREF, will be an object, i.e. completely opaque. Of course, it looks not good.
In java (jaxb) there is a way to hint the type referenced by IDREF, using jaxb:property, for example:

Thus, the generated code will be strongly typed: the field "myA" will have a type "a".
Is there such thing in a .NET?

Greatly appreciating any inputs,

Webservice reinitializes after deleting subfolder of website

Mon, 16 Nov 2009 17:04:51 Z

Hello

I'm developing a webservice at the following phisical disk address: C:\Inetpub\www\MyWebservice
The webservice accepts some files and puts them into some subdirectory like: C:\Inetpub\www\MyWebservice\files.
Binary files are stored in "bin" folder: C:\Inetpub\www\MyWebservice\bin.

From times to times the folder is moved by hand by some human operator. The webservice then recreates the "files" subfolder and continues to copy files as they arrive.

My problem is when the "files" folder is deleted (as the result of moving process), the webservice reinitializes. This means that all "static" data is lost. Static data stored on server side is like cached objects, "session" data, etc.

How can I prevent this behavior? I'd rather keep the storage folder under C:\Inetpub\www\MyWebservice path than moving to a totally different location like: D:\files. I know this would be a better choice but for now I need it that way.

Thanks anyone.

Web Service Problem

Fri, 13 Nov 2009 13:26:34 Z

Hi,

I have a problem when developing a web service. i have a dll that correspondes to a WS wrapper. When I had it as a reference to a project and create the Service object i have access to the Url attribute, just as if it was a web reference. but when i create my own web service and had the dll as a reference (not a web reference) and create the Service object i only have access to the web methods, and i don't know how to give access to all the attributes and methods i have in the wrapper dll.
I've already browsed for help and found mentions to use the SoapHttpClientProtocol but i still got nothing.
Can someone help or provide the guidelines on how to achieve this?

Thanks for any help provided
João

Soap Header

Wed, 11 Nov 2009 09:46:13 Z

Hi All,

I have an SOAP Message, WSDL file and added this file to my Windows Application. This webservice is not coded in .NET. The XML will be
<?xml version="1.0" encoding="utf-8"?>
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ns1="http://ws.ecprovws.bcs.com/" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<soapenv:Header>
<ecProvAuthHeader0><clientId>ClientId</clientId><clientKey>ClientKey</clientKey></ecProvAuthHeader0>
</soapenv:Header>
<soapenv:Body>
<createRegistrant xmlns="http://ws.ecprovws.bcs.com/">
<registrantWs xmlns="">
<conferenceId>ConferenceId</conferenceId>
<firstName>FirstName</firstName>
<lastName>LastName</lastName>
<email>Email</email>
<maxPin>MaxPIN</maxPin>
<pin>PIN</pin>
<role>Role</role>
<txId>TxId</txId>
</registrantWs>
</createRegistrant>
</soapenv:Body>
</soapenv:Envelope>

I have created a proxy class for the WSDL file and added to my windows application. I want to call a method
"createRegistrant" so I have used the below code
EcProvWsService objService = new EcProvWsService();
registrantWs objRegistrant = new registrantWs();
objRegistrant.email = "";
objRegistrant.conferenceId ="";
objRegistrant.firstName = "";
objRegistrant.lastName = "";
objService.createRegistrant(objRegistrant);

But for SoapHeader I am not able to create intance for "ecProvAuthHeader0" just like
ecProvAuthHeader0 obj = new ecProvAuthHeader0();
obj.ClientID= "";
obj.ClientKey = "";
objService.ecProvAuthHeaderoValue = obj;

So please anybody help me how to code for soap header in this case.

Thanks in Advace.

XmlSerializer don't call the Property_set

Wed, 11 Nov 2009 09:29:09 Z

I have a problem when I try to deserialize a List<T>.
the perfectly serialize to a Xml. But it doesn't deserialize.
When I use the debugger it seems that the set { } is never called.

here is a snippet of the code:

public abstract class ConfigurableObject {
        protected SortedList<string, ConfigurableValue> configVars = new SortedList<string, ConfigurableValue>();

        [XmlIgnore]
        public virtual SortedList<string, ConfigurableValue> ConfigVariables {
            get { return configVars; }
            set { configVars = value; }
        }


        protected ConfigurableObject() {
            configVars.Add("Description", new ConfigurableValue());
        }

[...]

        public virtual List<ConfigurableValue> ConfigList {
            get {
                List<ConfigurableValue> list = new List<ConfigurableValue>();
                foreach (KeyValuePair<string, ConfigurableValue> en in this.configVars) {
                    ConfigurableValue val = en.Value;
                    val.Name = en.Key;
                    list.Add(val);
                }
                return list;
            }
            set {
                foreach (ConfigurableValue val in value) {
                    if (this.configVars.ContainsKey(val.Name)) {
                        this.configVars[val.Name] = val;
                    }
                    this.configVars.Add(val.Name, val);
                }
            }
        }
[...]
}

All other properties are Fine.

Thanks.

CanDeserialize does not work with generated assemblies using sgen.exe

Fri, 13 Nov 2009 14:15:34 Z

Hi

I have the following example code to demonstrate my problem.

using System.Xml;
using System.Xml.Serialization;

namespace ConsoleApplication1
{
	public class Program
	{
		public static void Main(string[] args)
		{
			XmlSerializer serializer = new XmlSerializer(typeof(Example));
			XmlWriter writer = XmlWriter.Create("test.xml");
			Example input = new Example { Text = "Test" };

			serializer.Serialize(writer, input);
			writer.Close();

			XmlReader reader = XmlReader.Create("test.xml");

			bool canDeserialize = serializer.CanDeserialize(reader);
			Example result = (Example)serializer.Deserialize(reader);
		}

		[XmlRoot("example", Namespace = "http://tempuri.org/Example")]
		public class Example
		{
			[XmlAttribute("text")]
			public string Text { get; set; }
		}
	}
}

If I run this code, the value of canDeserialize is true (like it should be).

If I now add a post build step that speeds up the XmlSerializer constructor (and generates the serialization assemblies on compile time) the CanDeserialize method is not working anymore. It will return false, but the Example object is still deserialized correctly.

My post build step looks like this:
"[path to sgen.exe]\sgen.exe" "$(TargetPath)" /force

I tried the sgen.exe from the Windows 6.0A SDK (version: 2.0.50727.3038) and the one from the Windows 6.1 SDK (version: 2.0.50727.1432).
I'm using VS2008 and .NET Framework 3.5 SP1.

Did I do something wrong or is this a bug?

Thanks for the help.

Web Services Memory Leak

Fri, 07 Dec 2007 15:22:33 Z

Hi,

I am writing a C# web service. But I am having memory leak problem with the web services.

To check the problem, I created a simple web service with just one function that will take two integers as parameters and return their addition. I created an application that consumes this web service and ran it for 10000 times.

But even this simple web service was consuming memory. I used the ANTS memory profiler to check the memory consumption. It showed that ‘Hashtable+bucket[]’ object is consuming most of the used memory. Looks like this object is storing server identity IDs for all the connections.

What exactly this object stores? Is there any way to release the memory used by this object? Or can we avoid using this object? How can I stop memory leak problem for the web services?

Thanks.

Global.asax Application/Session_Start is never called from ASP.NET 3.5 web service

Thu, 12 Nov 2009 00:12:54 Z

I've been beating my head against the screen trying to get log4net working in my 3.5 web service. Per community instruction, you should add the following line to the Global.asax.cs file:

void Application_Start(object sender, EventArgs e)

{

// Code that runs on application startup

log4net.Config.XmlConfigurator.Configure();

}

However, after trying to catch a break in the debugger (see this), I'm pretty confident that the Global.asax file is being ignored completely. Has anyone had any success with log4net/Global.asax/Application_Start in an ASP.NET 3.5 web service?

Obtaining IP Address of Client

Pass 2 Parameters from Two DropDownLists to GridView

Sun, 15 Nov 2009 17:53:38 Z

I am trying to figure out a way to NOT display any items in my DropDownList when my page loads. I’m linking to a list of states in my DB and Alabama, and related information, is always displayed on the page as soon as the page loads. I’d really like the page to load and show only the DropDownBoxes and then I’ll pick an item from the list and display all records, in my GridView, that match.

Also, I am trying to figure out how to update one DropDownList based on what is selected in another drip down list. For instance, if I pick Arizona as a State and Corporate Deduction as a Topic (Topic is my second DropDownList) I’d like to see only those items that match both Arizona and Corporate Deduction. This would allow me to drill down into the data and display only specific records rather than displaying lots of records, which is what I am doing now. Right now, my GridView is linked to ObjectDataSource1, and this is linked to a DataSet1, and this essentially has all my data in the DB, filtered by State. It’s pretty easy to link the GridView to a DropDownList and pass the selected parameter to the filter and display only records that match that parameter. I can’t figure out how to get the GridView to point to two (or more) DropDownLists. And I can’t figure out how to filter for two parameters, using two separate DropDownLists (or more), and pass both of these parameters to the GridView.

Please help!!

Thanks,

XmlSerializer Deserialize() does not work with a wrapping validating XmlReader

Fri, 13 Nov 2009 14:36:22 Z

Hi

The main question for me probably is: What changes if I wrap an XmlReader with another XmlReader?
I have the following case:
- I check with XmlSerializer.CanDeserialize if I can deserialize an object from a XmlReader.
- After that I deserialize the object from the XmlReader.

Everything works fine.
Now I wanted to add a schema validation, so I wrapped the XmlReader with another XmlReader doing the validation against a schema.
Deserializing the object is now not working anymore. As a result I get an object of Type Example, but the Text property is null.
The validation works. If I omit the text-attribute in the xml file, the validation throws an exception that the text-attribute is required.

So what changed with the wrapping of the XmlReader? Shouldn't the wrapping reader behave just like the unwrapped reader?
I know that the check of CanDeserialize has something to do with the problem. If I don't do that check deserializing will work.

Here is my example code:

using System.Reflection;
using System.Xml;
using System.Xml.Serialization;

namespace ConsoleApplication1
{
	public class Program
	{
		public static void Main(string[] args)
		{
			XmlSerializer serializer = new XmlSerializer(typeof(Example));
			XmlWriter writer = XmlWriter.Create("test.xml");
			Example input = new Example { Text = "Test" };

			serializer.Serialize(writer, input);
			writer.Close();

			XmlReader reader = XmlReader.Create("test.xml");

			if (serializer.CanDeserialize(reader))
			{
				XmlReaderSettings settings = new XmlReaderSettings();
				settings.ValidationType = ValidationType.Schema;
				settings.Schemas.Add("http://tempuri.org/Example", XmlReader.Create(Assembly.GetExecutingAssembly().GetManifestResourceStream("ConsoleApplication1.Example.xsd")));

				XmlReader validationReader = XmlReader.Create(reader, settings);

				Example result = (Example)serializer.Deserialize(validationReader);
			}
		}

		[XmlRoot("example", Namespace = "http://tempuri.org/Example")]
		public class Example
		{
			[XmlAttribute("text")]
			public string Text { get; set; }
		}
	}
}

And the example xsd file (that is included as an embedded resource):

<?xml version="1.0" encoding="utf-8"?>
<xs:schema id="Example" targetNamespace="http://tempuri.org/Example" elementFormDefault="qualified" xmlns="http://tempuri.org/Example" xmlns:xs="http://www.w3.org/2001/XMLSchema">

	<xs:element name="example">
		<xs:complexType>
			<xs:attribute name="text" use="required" type="xs:string"/>
		</xs:complexType>
	</xs:element>
</xs:schema>

Thanks for the help.

I am reading a string with carriage returns and new lines into a string.

This string is later added to a xml, serialised, written to the db.

How to get the object being deserilize

Thu, 12 Nov 2009 07:30:10 Z

Hi,

I am trying to Set values using reflection under UnknownElement event.

The problem is that I am getting the PerentNode in XmlElementEventArgs e.ObjectBeingDeserialized and not the root object I am trying to deserialize.

The root object is also a singletone object if its matter.

I need to know if theres a way to get the root object that is being deserialized.

Code exmple (where the objectBeingDeserialized is the what I can't manage to get)

   //try to find the appropriate collection property
            FieldInfo fInfo = objectBeingDeserialized.GetType().GetField(fieldEntityName, BindingFlags.Instance | BindingFlags.NonPublic);

            //if the field exist
            if (fInfo != null)
            {
                    //set value to field
                    fInfo.SetValue(objectBeingDeserialized, entity);
              
            }

Any help will be mostly appriciated.

ERROR_NO_DATA was thrown sometimes by web service/SOAP

Fri, 06 Nov 2009 05:23:29 Z

I've a web service on machine A which also has a WS client (for my experiment purpose). If I keep looping to call a WS foo(), occasionally I will get ERROR_NO_DATA HResult from the service. What is the reason and how do I eliminate this exception at all, if possible?

Any pointer is appreicated.

Deserializing a node which has the xsi:type specified

Wed, 11 Nov 2009 11:13:52 Z

Hi

This isn't in relation to ASMX web services, but is a XMLSerializer problem so I hope I've got the correct forum.

Basically I have a simple custom object which is for a value in my database. I've defined it like this:
public class PropertyValue
    {
        [XmlAttribute("type", Namespace = "http://www.w3.org/2001/XMLSchema-instance")]
        public string Type { get; set; }

        [XmlText]
        public string Text { get; set; }
    }

and it's used as the property of another object :
[XmlRoot(ElementName = "Property")]
    public class MyProperty : MyListItem
    {
        [XmlAttribute]
        public String Address { get; set; }

       .....

        [XmlElement]
        public PropertyValue Value { get; set; }

       .....
    }

When returning the details from the database I use the xml serializer to change the objects into xml and it spits out code like this:
<Property Address="this is the address">
......
<Value xsi:type="http://www.w3.org/2001/XMLSchema#decimal">3.14159265358979</Value>
....
</Property>

Which is what I was wanting - but the problem is that I also need to accept xml (this method is part of a WCF operation) and deserialize it back into the object. My WCF operation accepts a stream which is the xml, and *should* deserialize but bugs out.
If I pass in this:
<Property>
...
<Value xsi:type="http://www.w3.org/2001/XMLSchema#decimal">3.14159265358979</Value>
</Property>
I get error "Undefined namespace "xsi".

If I change to this:
<Property xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
...
<Value xsi:type="http://www.w3.org/2001/XMLSchema#decimal">3.14159265358979</Value>
</Property>
I get error "undefined namespace "http" (which really confuses me)

If I remove and just use "type" as below, if deserializes without error but the Type property of the PropertyValue object is null.
<Property>
...
<Value type="http://www.w3.org/2001/XMLSchema#decimal">3.14159265358979</Value>
</Property>

My deserialization test code is:
[Test]
        public void TestDeser()
        {
            string dataType = "http://www.w3.org/2001/XMLSchema#decimal";
            string value = Math.PI.ToString();

            string xmlstring = string.Format(
                    @"<Property xmlns:xsi=""http://www.w3.org/2001/XMLSchema-instance""><Value xsi:type=""{1}"">{2}</Value><Scope/></Property>", propTypeSi, dataType, value);

            Stream s = new MemoryStream(Encoding.Default.GetBytes(xmlstring2));

            Type type = typeof (MyPropery);
            var xser = new XmlSerializer(type);

            var output = xser.Deserialize(s) as MyListItem;
            var prop = output as MyProperty;
            //if we've managed to get this far I still end up with prop.Value.Type = null
}

I'm stuck! If anyone could help I'd really appreciate it!

Data Compression when Uploading to ASP.NET 2.0 Web Service

Tue, 10 Nov 2009 21:00:22 Z

Hi

I think I have a problem that hasn't been covered in this forum before: Is it possible to implement data compression in ASP.NET 2.0 web services when uploading data to the web service from a client? We are using HTTP POST not SOAP to transmit the data.

Background: I'm dealing with a server-side application that allows handheld devices to upload scanned barcodes via an ASP.NET 2.0 web service. 99% of the traffic is going from the handheld devices to the server - up to 500,000 scanned barcodes a day.

We ditiched SOAP in favour of HTTP POST to get the sizes of the messages down. Each message is fairly short (a few hundred bytes) and we found the overhead of all those SOAP headers markedly increased the message size. The reason we want to get the message size down as much as possible is that the data is sent over a cellular network. The network operator charges on the total amount of data sent, not on the number of messages.

The guys who write the code for the handhelds (in Visual C++) say they will have no problem implementing data compression. I just have to figure out how to decompress it at the server side.

All the posts I've found on this forum, and other articles I've seen on the web, deal with compression when downloading data, not uploading it. I assume decompressing data is possible on the server side but how difficult is it? Does it just involve some simple setting like AutomaticDecompression, or perhaps creating a derived class from System.Web.Services.WebService (and then deriving the web service classes from that derived class), or does it involve something more complicated?

Cheers

SoapHttpClientProtocol CancelAsync how does one make this work?

Tue, 10 Nov 2009 20:30:34 Z

Hello,

How do you cancel an Async method call to a web service?

We have a web proxy which calls a web method on our web service.

The web method UploadEncounter uploads a byte array from the client application to the web service server.

We wish to cancel this upload either by a User action (button press) or in reaction to a timeout with in the application.

We have had no success when calling the proxy's Abort() or CancelAsync.

The registered callback shows the Cancel being completed or the Abort occurring yet the data of the byte array still continues to be transfered to the sever via the web service.

The web proxy class

public partial class DataSync : System.Web.Services.Protocols.SoapHttpClientProtocol

The function in the web proxy

public void UploadEncounter(byte[] bytes, string vchClientId, bool bProcess, object userState) {

if ((this.UploadEncounterOperationCompleted == null)) {

this.UploadEncounterOperationCompleted = new System.Threading.SendOrPostCallback(this.OnUploadEncounterOperationCompleted);

}

this.InvokeAsync("UploadEncounter", new object[] {

bytes,

vchClientId,

bProcess}, this.UploadEncounterOperationCompleted, userState);

}

The operation completed function

private void OnUploadEncounterStressOperationCompleted(object arg) {

if ((this.UploadEncounterStressCompleted != null)) {

System.Web.Services.Protocols.InvokeCompletedEventArgs invokeArgs = ((System.Web.Services.Protocols.InvokeCompletedEventArgs)(arg));

this.UploadEncounterStressCompleted(this, new System.ComponentModel.AsyncCompletedEventArgs(invokeArgs.Error, invokeArgs.Cancelled, invokeArgs.UserState));

}

The application calls

// datasync web proxy class

datasync.UploadEncounterStressAsync(buffer, "AsyncStressTest", false, "<<WG>>");

datasync.UploadEncounterStressCompleted += new UploadEncounterStressCompletedEventHandler(datasync_UploadEncounterStressCompleted);

the callback handler

void datasync_UploadEncounterStressCompleted(object sender, AsyncCompletedEventArgs e)

{

//WE unhook the handler

datasync.UploadEncounterStressCompleted -= datasync_UploadEncounterStressCompleted;

// WE write a log here to report the returned stats

TextLog(string.Format("Returned Upload Encounter{0} # {1} of {2} \t Time {3} Milliseconds \t Cancelled {4} \t Error = {5} ",

EncounterId,

success,

total,

ts.TotalMilliseconds ,e.Cancelled.ToString(),(e.Error != null) ? e.Error.ToString():"No Error"

));

}

// handles a button press from the user to cancel the upload

private void btHaltTest1_Click(object sender, EventArgs e)

{

// Attempts to Cancel return a success but the data continues to the server!!!!

datasync.CancelAsync("<<WG>>");// call the web proxy's CancelAsync

// Attempts to Abort return a exeception but the data continues to the server!!!!

//uncomment datasync.Abort(); // or call the web proxy Abort

// we report to a log

TextLog(string.Format("Canceled UploadEncounter Encounter {0} \t Time Taken {1} milliseconds", EncounterId, ts.TotalMilliseconds));

}

thanks

Removing namespaces on child elements from serialised object

Sat, 07 Nov 2009 22:05:26 Z

Hi all,

I am serialising a collection types and on the attributes, which have been serialised as child elements, and each of these child elements has the default namespace on them (http://tempuri.org/ ). Now I know these has come down from the object that has been serialised, but is there anyway I can remove these namespaces (or replace then) during the serialisation process?

The XML output I am getting is as follows...

<SearchCompany>
  <Company_ID xmlns="http://tempuri.org/">98838401</Company_ID> 
  <CompanyName xmlns="http://tempuri.org/">3X Bankprojekt GmbH</CompanyName> 
  <CompanyNumber xmlns="http://tempuri.org/">510620</CompanyNumber> 
  <CompanyStatus xmlns="http://tempuri.org/">active</CompanyStatus> 
  <Street xmlns="http://tempuri.org/">St.-Martinus-Str. 3</Street> 
  <City xmlns="http://tempuri.org/">Ellwangen</City> 
  <Postalcode xmlns="http://tempuri.org/">73479</Postalcode> 
  <LastAccountsDate xmlns="http://tempuri.org/">0</LastAccountsDate> 
  <CreditScore xmlns="http://tempuri.org/">0</CreditScore>

Thanks in advance.

How do you apply XmlWriterSettings to a XmlTextWriter object?

Sun, 08 Nov 2009 18:47:34 Z

How can you apply an XmlWriterSettings object to a XmlTextWriter object? There is no parameter in the XmlTextWriter constructor that takes an instance
of XmlWriterSettings, and when you try to assign to the Settings property of the XmlTextWriter object I can't, as it is read only :-s

My code is as follows...

XmlWriterSettings objXmlWriterSettings = new XmlWriterSettings();
objXmlWriterSettings.Indent = true;
objXmlWriterSettings.OmitXmlDeclaration = false;

using (XmlTextWriter objXmlWriter = new XmlTextWriter(string.Format("{0}{1}", RootPath, TransformationResultsXmlPath), null))
{
	objXmlWriter.Formatting = Formatting.Indented;
	objXslTransform.Load(string.Format("{0}{1}", RootPath, TransformationXsltPath));
	objXslTransform.Transform(objXpathDoc, null, objXmlWriter);
}
