Connect To WCF Web Service
Jan 24, 2011
I'm new to WCF web services never done anything with them before and I'm being asked to create a page to connect to a WCF web service I have no idea where to start and I've searched the internet with no success. Does anybody have an example of an asp.net page connecting to a WCF web service? I've set up the WCF web service on my server but do not have a clue on how to actually connect or query it to get my XML data back.
The WCF web service is set up as it's own URL and only has 2 files within the root one being the web.config. I somehow need to query this URL and get some XML data back from it.

I have an ASP.NET web app where I use an ado sql connection to connect to a database on a SQL Server. The ado connection string is provided with a user login that has sufficient rights to read/write to the database. I originally pushed out the web app in its own IIS web site, using its own application pool and everything worked fine.
However, I am now trying to include the web app under an already existing web site. Everything seemed to work fine until I tried any functionality that called for an INSERT or UPDATE to the database. It turns out the user connecting to the DB didn't have sufficient permissions. Finding this strange, I did some research and found a forum post that suggested the IIS Web Site service account needed read/write permissions in the SQL database in order for an app to perform INSERT/UPDATE. Is this true?
I tested it out, and yes, indeed it worked, only with the Application Pool Identity account. The deatails of my scenario are as follows:
The web app's first IIS Web Site had an application pool Identity that ran under NETWORK SERVICE, which already had a login for SQL SERVER The already existing web site's application pool Identity runs under a domain account. This site already runs another web app that connects to the same database using LINQ (developed by someone else). I am relatively new to web development and am more familiar with ADO, so that is the route I chose.The domain account mentioned above formerly had no SQL Server login/user mapping. I set it up as a dbowner, and viola, the new web app worked under the existing web site.
While I found a way for it to work, we would rather not create a SQL login for this Identity account. We want the login provided in the web app's ADO SqlConnection to be the one to actually connect, because isn't that the point of it?

Iīm learning how to use a web service with flash.
Now I need to connect the web service to my db.
This is what I tried:
Code:
Public Function HelloWorld() As String
Dim orgcon As New OLEDBConnection("Provider=Microsoft.jet.oledb.4.0;data source=c:dataDB.MDB")
Dim OrgDA As New OleDbDataAdapter("select * from organization order by orgname", orgcon)
Dim Orgds As New System.Data.DataSet
OrgDA.Fill(Orgds, "Organization")
Dim hwstring As String
hwstring = orgds.tables(0).rows(0).item(3).tostring
Return hwstring
End Function
The flash just gives me an error that there was an error opening the web service. For some reason I canīt debug it in vwd.

I have a website project in VS 2005 using VB. From it I connect to a web service that sends an email. This was running just fine until my department moved locations (and along with it the server hosting the service). Now my project can't connect to the service. I deleted and added the web reference again and VS found it and it's methods just fine. I can browse to the service in my browser successfully.
The emails are no longer getting sent and there is no error raised. I tried debugging and when I step into the call to the service then I get the error "Unable to automatically step into the server. Connecting to the server machine '[mywebservice]' failed. ...". I do not need to debug that service; I was only confirming that the project wasn't connecting.
When the project is loaded onto our virtual server for testing it runs as expected.
How can I get my project to connect to the web service from my localhost as it was before the machine was moved?

I have an existing windows .net application that has an access database as the backend.
I want to place the access database on a web server and it was suggested that I create a web service in order to communicate with the database.
I've been looking at some tutorials but am still confused about the basic config needed. Here's some questions I have:
1) Does the web service need to be created inside my current project by right clicking on the solution and choosing to add a new web site...and then selecting web service?
2) If it's set up like this, what files do I place onto the web server?
3) Where does the database reside? Do I need to place the database inside the web server that I create?
4) My current project has existing sql that gets data and I'm uncertain how to re-write in order to retreive the data. e.g. which part goes into the client and which part goes to web service pages? here's an example of a procedure that currently exists...I'm getting data to populate a dropdown:

I have got this error
Unable to connect to the remote server
when I call the web service from the windows service. But I can visit this web service through IE and I also wrote another console application to call the web service and it works fine, too.
The exception infomation is below:
A socket operation was attempted to an unreachable network 127.0.0.1:8888
Here is my code:
WebImageSVC webSvc = new WebImageSVC();
ConfigManager.LoadConfigManager();
webSvc.Url = ConfigManager.WebSvcAddress;
webSvc.Proxy = null;
webSvc.CanUpload(0, "");
I try many methods, like turn off the firewall and anti-virus software, set the web services proxy property to null. but still cannot solve this issue.

I have built a WCF Service that is being consumed by a Silverlight app. At first I created one method that was very simple:
public String SfTest()
{
return "SF Test";
}
No poblem. My silverlight app references my service and displays "SF Test" in a textbox. Now I add a method to my wcf service like this:
public List<String> GetTest()
{
List<String> list = new List<string>();
String a = "a";
list.Add(a);
String b = "b";
list.Add(b);
return list;
}
I update the reference to the service in my Silverlight app and the using statement in my xaml cs page throws an error like the service doesn't even exist although it is there. I am assuming the problem has to do with datatypes or serialization or something like that but it is driving me up the wall. Why can't I consume a simple generic list in my Silverlight app through the WCF service.

I developed a web service in VS2010 on my local machine, wrote a consumer of it also locally, and that all works.
I copied the dll and the asmx file to our server, and I am getting an error when I try to invoke it from a browser (also still on the server machine) to make sure it correctly exposes its web methods, but it is not, it is saying "Could not create type 'Service'". That error comes from this line:
Line 1: <%@ WebService Language="C#" CodeBehind="~/App_Code/WarrantyDuplicate.cs" Class="Service" %>
There other web services in the same folder on the server that all work fine so I don't believe it's an IIS setup thing.
This is my first web service in C# and when I created it in VS I did think it odd that the code behind file went into App_Code (as you can see from the line in the asmx file) and is just named dot-cs rather than asmx-dot-cs. But since it worked fine locally, I wasn't sure that mattered.

I am not sure which approach I should use. I have a web application that needs to get/receive data from a third party application that is in a secure remote network. The data needs to be secure during transport. The data layers cannot be exposed and the databases will not talk to each other. The data will be received from remote application on demand, or will get at scheduled intervals.
I have looked at WCF, but not sure if this will work. Can a WCF service be used to receive data as needed from a remote sender or service? Is this a secure way of doing it? I have also looked at SFTP using some XML/XSLT, but I don't think this is the right way to go. In addition, some data may be transported from my web application to the remote application (mostly reports at first). What protocols are used to transfer data between HIPAA compliant applications?

I am writing two ASP.NET apps. One is a web service that provides xml data and the other is a web client that will use the service to display and manipulate data. I would like for the web service to do the membership authentication and authorization. Is there any way to simply point the login controls in my client application to the web service instead of to a database. I assume I would have to provide the necesarry methods in my web service interface, which would then use the membership provider database I created and pass the results back through to the client.
Is this possible? I have seen many articles on security provisioin from a web service but none has really been what I am looking for. I was hoping that, since my service and my client are both written in ASP.NET, there might be some built functionality that would benefit me.

I'm currently trying to work out the best way to build this web application, which will then be intergrated on other systems, such as WinForms, Intranets etc.
We hope to include the usual layers i.e. DAL, BLL, BOL and UI but I have been experimenting with Entity Framework 4 and WCF Data Services and managed to get something in place where I was using WCF as a gateway to EF4.
i.e. Adding a Service Reference to my project and then using the EF4 context and writing LINQ queries against the DB
e.g.[Code]....
Now with the current setup I would still need to write a DAL Class Library, that interacts with the Data Service, because as I said WCF Data Services only seems to be a gateway, I can't see where to put the code (above) in the Data Service and then how I could these methods.
My questions are: 1. How do I develop a WCF Data Service in such a way to allow this behaviour - I know how I could do it using ASMX web service, something like [Code]....
2. If I am to use WCF Data Services, how is serialization handled (if at all) - again I know how to do something in ASMX web services
3. Again, If I am to use WCF, how do I add Security and only allow my applications to access the web service - for obvious reasons
4. Would it be possible / logical to also include the Business Logic Layer into the web service?

Is it possible to run a web service as a particular user/service account in the same way a Windows service can?I have a service account used for connecting to the DB and want to run the webservice under this account as the users using the webservice won't have DB access.The way I see to do it is to include the Impersonate option in the Web.config file, but is there any better way to do this?

My WCF Client calls my WCF Service which then calls ASMX Web Service. The problem is i have configured my wcf client and wcf service to windows credentials type but when wcf service calls asmx service the user credentials (default windowsidentity) is not passed to asmx service.
In WCF Service i am able to get user identity by using : Thread.CurrentPrincipal.Identity.Name;
WCF Service - i have disabled anonymous access and enabled windows authentication. ASMX Web Service - i have disabled anonymous access and enabled windows authentication.
