Problem to obtain client IP on web service



I'm having problems to obtain the client IP on web service. Here's my scenario:

One server with Windows 2003, hosting the web service using .Net Framework 2.0, with IP and host name ServerTransaction.
Other server with Windows 2003, hosting a web application using .Net Framework 2.0, that consuming the web service on  ServerTransaction, with IP and host name ServerApplication.
Many other computers on the local network (IPs:,,, ...) acessing the web application on ServerApplication.

On the code of the web service I've tried to use HttpContext.Current.Request.UserHostAddress or HttpContext.Current.Request.ServerVariables("REMOTE_ADDR") or HttpContext.Current.Request.ServerVariables("HTTP_X_FORWARDED_FORR"), but always I can only get the IP of ServerApplication (

Any idea or tip?

Thanks and sorry for my bad english.

Hosting web service inside Windows Application

  I would like to host my web service inside windows application. I prepared a short example basing on: http://msdn.microsoft.com/en-us/library/aa529311.aspx I have 2 projects created with default templates: Web Service project where I did not change anything: namespace WebService1 { [WebService(Namespace = "http://tempuri.org/")] [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)] public class Service : System.Web.Services.WebService { public Service() { } [WebMethod] public string HelloWorld() { return "Hello World"; } } } Windows Project in which I changed only the main form class: public partial class Form1 : Form { public Form1() { InitializeComponent(); Uri address = new Uri("soap.tcp://localhost/TestService"); SoapReceivers.Add(new EndpointReference(address), typeof(WebService1.Service)); } } The problem is that when I compile and run this Windows Application, I can`t discover this Web Service. There must be something wrong in my solution. Could you please help me by telling what may be wrong? Thank you for help in advance.MCP

Problems with using SPSite inside a Web Service (presumably credentials problem)

Greetings. I need to write a web service which will access sharepoint via object model (need to output data from lists, and no, built-in sharepoint web services are useless to me since they totally suck if you dont have an english-language site) In the code of my web service, i use something like this:   Site = new SPSite(SiteLink); Web = Site.AllWebs[""]; And then i use Web.Lists to get my list and work with it. It works, unless i put the webservice on. I mean, when the webservice is launched from Asp.net deveopment server, it works fine. When i made a website in IIS pointing it to my webservice, it now spits this error:   System.IO.FileNotFoundException: ?? ??????? ????? ???-?????????? ?? ?????? http://localhost/sites/test/. ?????????, ????????? ?? ?????? URL-?????. ???? ???? URL-????? ???????????? ??? ????????????? ???????м???, ???м????, ?????м??м? ??м??????????? ??????????? ???????? ????? ????????????? URL-?????? ??????? ? ?????м ??????????м. at Microsoft.SharePoint.SPSite..ctor(SPFarm farm, Uri requestUri, Boolean contextSite, SPUserToken userToken) at Microsoft.SharePoint.SPSite..ctor(String requestUrl) at IstrebitelProperListWebService.SchemaExporter.SetSite(String siteLink) in C:\Users\Administrator\Documents\Visual Studio 2008\Projects\ProperListWebService\ProperListWebService\IstrebitelProperListWebServ

getting web service interface from inside web service


We have a process that loads multiple dll assemblies each of which contains multiple service interfaces hosted by one or more actual services.  Some of our components need to be able to call other services internally.  Of course I do not want the overhead of marshalling / opening a channel / etc.

Since services can be singletons or created each time, I am trying to find a way to get the service or interface through the wcf architecture that handles this.

Does anyone know of a way?

WCF Service hosted inside SharePoint 2010's ISAPI folder and MaxReceivedMessageSize


I got a WCF service hosted inside the SharePoint 2010 following this article http://answers.oreilly.com/topic/1404-how-to-customize-wcf-services-in-sharepoint-2010/

Everything was going great until I wanted to increase the MaxReceivedMessageSize however there is no configuration file for this service.

I tried to add a configuration file to be deployed along with the svc service in the same directory inside the ISAPI mapped folder but I get this error:

The service '/_vti_bin/epcc/messagesarchive/contactssearcher.svc' cannot be activated due to an exception during compilation.  The exception message is: Could not find a base address that matches scheme http for the endpoint with binding BasicHttpBinding. Registered base address schemes are []..

Here is my configuration,

   <service name="WCFServices.ContactsSearcher.ContactsSearcher" behaviorConfiguration="ContactsSearcherBehavior">
    <endpoint address="ContactsSearcher"
    <endpoint address="mex"

Web Service to inherit from a Custom Base Class that inherits System.Web.Services.WebMethod instead


Hi All,

    Inherits System.Web.Services.WebService

    public property Property1 as string
    public property Property2 as string

Please kindly assist.

Thank you in advance.

Windows Service Applications Tutorials

You can easily create services by creating an application that is installed as a service. For example, suppose you want to monitor performance counter data and react to threshold values. You could write a Windows Service application that listens to the performance counter data, deploy the application, and begin collecting and analyzing data.

Accessing the different controls inside a GridView control

how we can access a particular control which resides inside a GridView control. In this article I will show you how you can access different controls inside a GridView control.

WCF Tip: Using Properties in Service Contracts

you'll notice all of the Service Contracts are implemented with interfaces containing only methods. For the longest time I thought that's all that was supported, until I thought about it a little more. In C# land, properties are simply wrappers around a get method and set method, so why wouldn't we be able to use properties in a service contract? Well the answer is we can.

Realizing a Service-Oriented Architecture with .NET

This article is meant to be a practical discussion guide to building a .NET application in a service-oriented architecture. We will consider real-world goals, real-world obstacles, and experience-based solutions. I quickly concede the approaches discussed here are not exhaustive or infallible. This paper is focused on application development, not application integration. We will specifically consider architectural issues and component design issues.
