How to establish a connection between a web service and windows service

Posted By:      Posted Date: May 22, 2011    Points: 0   Category :ADO.Net
I must establish a connection between a web service and windows service. And i need some sort of listener between these two components when the connection is done both componenets must be informed. such as Web services will send an error message to the end user and the service windows will do a rollback of the operation he was doing.

What is the best way to implement this scenario.

Please help me with a speedy reply

Thanks in advance

Connection Pooling VS Steady Connection in Windows Service Application


Hi All,

We are developing a windows service application which queries the sql db every second. For now, we have enabled connection pooling and every time we open and close connection at every access. Since it is a windows service can I open connection at service startup and close the connection shutdown

Please let me know the right approach in this scenario.





Connection times out when WCF client tries to call WCF service, both in Windows Forms apps



The exception message is: Could not connect to TCP error code 10060: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond

What I am trying to do: a WCF service is self hosted in a Windows Forms application. The WCF client is in another Windows Forms application. Eventually, the client is supposed to run on a computer somewhere out there on the Internet and send messages to the server which is running on my home computer. This is my first attempt at making a remote WCF call.

I have success when server and client either run on the same computer, or are running on different computers attached to my little in-home LAN. When I try to route the client's request via Internet (in preparation for having the client reside out there somewhere) I get the exception reproduced in the first paragraph above after waiting for about 20 seconds.

OS is WinXP Pro with SP3. Using Visual Studio 2008, Visual Basic. is the IP currently assigned to me by Comcast (I watch carefully to see when it changes; also, I altered it for purposes of asking this question).


Connection problem when connecting from windows service in Windows 7 embedded


Hi everyone

I'm trying to migrate our applications working with SQL Server 2005 Express from Windows XP to Windows 7, and have following problem. Desktop applications connect to SQL Server fine, but windows service app returns following error when trying to connect: [DBNETLIB][ConnectionOpen (SECCreateCredentials()).]SSL Security error

I tried installing service under localsystem account and under desktop user account with no success.

My connection string looks like Provider=SQLOLEDB.1;Password=password;Persist Security Info=True;User ID=user;Initial Catalog=data;Data Source=servername

I've searched a bit about this error and one recommendation was to try to use SQL Native client, so I tried to change my connection string to

Provider=SQLNCLI;Pwd=password;UID=user;Database=data;Server=servername, this also works when running from desktop but when running from windows service I get another error

SQL Network Interfaces: The requested security package does not exist

This seems to be purely client problem because when I use wrong server name I still get the same errors.

I guess something changed with permissions of services in Windows 7

Any ideas what could be wrong and how to fix it?

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.

Windows Services: New Base Classes in .NET Make Writing a Windows Service Easy


Windows services are applications that run outside of any particular user context in Windows NT, Windows 2000, or Windows XP. The creation of services used to require expert coding skills and generally required C or C++. Visual Studio .NET now makes it easy for you to create a Windows service, whether you're writing code in C++, C#, or Visual Basic. You can also write a Windows service in any other language that targets the common language runtime. This article walks you through the creation of a useful Windows service, then demonstrates how to install, test, and debug the service.

Getting AppDomain.UnhandledException event to work in a Windows Service

Nearly every forum thread I have found on "catching unhandled exceptions in a service" seems to end up where I am.  The supposed solution is the use of the AppDomain.CurrentDomain.UnhandledException event.  But it doesn't work for someone, who then asks why and gets no answer.  Same for me; I can't get the event to happen.  It's as if I need the ServiceProcess version of Application.SetUnhandledExceptionMode(), which doesn't exist. For diagnosing this, I start a timer in a child object of the service and then throw an exception in the timer event handler.  Simple enough to simulate the real situation.  I have tried subscribing to the UnhandledException event in at least a half dozen locations throughout the service, from the Program that runs ServiceBase.Run() to the constructor of the object that owns the Timer, but it never catches this exception. The VS debugger recognizes that the forced exception is unhandled and takes me to the place where is thrown, letting me know it is an unhandled exception. Why doesn't my handler catch it?  Running without the debugger, the exception throws, the timer thread crashes, the service continues merrily along, and nothing gets logged anywhere.  That is NOT the result I need.  What are the people for whom this works doing that I am not doing? How can I at least get the offe

Windows Identity Foundation Security Token Service can't stay logged in

I'm using the Windows Identity Foundation **(WIF)** Security Token Service **(STS)** to handle authentication for my application which is working all well and good. However I can't seem to get any long running login with the STS. From my understanding I shouldn't care about the client tokens at the application level since they can expire all they want to and it should redirect me to the STS and as long as they're still logged in on the STS it should refresh their application token. Yet it doesn't seem to want to keep them signed in. Here's what occurs in my login.aspx on the STS var cookie = FormsAuthentication.GetAuthCookie(userName, persistTicket); if (persistTicket) cookie.Expires = DateTime.Now.AddDays(14); Response.Cookies.Add(cookie); var returnUrl = Request.QueryString["ReturnUrl"]; Response.Redirect(returnUrl ?? "default.aspx"); Which was taken almost directly from existing application using normal Forms Auth. From my web.config <authentication mode="Forms"> <forms loginUrl="Login.aspx" protection="All" timeout="2880" name=".STS" path="/" requireSSL="false" slidingExpiration="true" defaultUrl="default.aspx" cookieless="UseDeviceProfile" enableCrossAppRedirects="false" /> </auth

Cash Drawer - Method Open threw an exception - Windows Service

Hi All, I'm getting the following exception while calling Open method of Cash Drawer object. Method Open threw an exception.  Could not read the device name key's default value, or could not convert the Programmatic ID it holds into a valid Class ID. Code:   class Class1 { CashDrawer _uniCashDrawer1 = null; DeviceInfo cashDrawerDevice1 = null; PosExplorer posExplorer = new Microsoft.PointOfService.PosExplorer();   public void ClaimCashDrawer() { cashDrawerDevice1 = posExplorer.GetDevice("CashDrawer", "testDrawer"); if (cashDrawerDevice1 != null) { _uniCashDrawer1 = posExplorer.CreateInstance(cashDrawerDevice1) as CashDrawer; if (_uniCashDrawer1 != null) { _uniCashDrawer1.StatusUpdateEvent += new StatusUpdateEventHandler(UniCashDrawer1_StatusUpdateEvent); _uniCashDrawer1.Open(); _uniCashDrawer1.Claim(0); _uniCashDrawer1.DeviceEnabled = true; } } } }   Tha above code works fine if you put the code in WindowsApplication in all POS systems. The same is working if you put the code in Windows Service in all other POS systems. The same is not working if you put the code in Windows Service in Aures Galeo POS systems.  Thanks in advance.

How can I debug Windows Service using Visual Studio?

How can I debug Windows Service using Visual Studio? I wrote in Visual Studio 2008 Command Promt: installutil -i c:\projects\MyProject\bin\debug\win.exe I did Start to may service ,but every time that I want to debug service I get: Cannot start service from the command line or a debugger. A Windows Service must first be installed (using installutil.exe) and then started with the ServerExplorer, Windows Services Administrative tool or the NET START command.   What am I doing wrong?   Thanks, Raya        

logoff doesn't work through windows service

Dear Friends, I am facing this problem on Windows 2003 and 2008 Server. On XP it works fine. I have written and Windows Service that takes receives the command and executes tasks such as Logoff, Shutdown, etc. All the commands except Logoff works fine. I tried following ways to perform the Logoff. However it didnt work. Try 1:                 Process.Start("shutdown", "-l"); Try 2:     [DllImport("user32.dll")]     public static extern int ExitWindowsEx(int uFlags, int dwReason);     ExitWindowsEx(0, 0); Try 3:     Process _currentProcess = new Process();                _currentProcess.StartInfo = new ProcessStartInfo("shutdown", "-l -f");                _currentProcess.StartInfo.UseShellExecute = false;                 _currentProcess.Start(); Try 4:     Process.Start("logoff.exe", null); If I write a simple C# based applicatin (not Service) it works fine for all the tries that I have made. I am facing this problem only when I put this code

Question about WCF Service hosted in Windows Service

Hi, I have little experience with WCF and working on a projet that requires WCF Service instance to run 24x7. After searching for a solution and reading about WCF, I think if I host it under Windows Service I can have a single instance of WCF Service running 24x7. Is this correct? I just successfully ran the MSDN sample project that hosts CalculatorService in Windows Service. I realized that Windows Service cannot communicate with WCF Service it is hosting (I do not have any experience with writing Windows Service). I wrote a test function (public) in Windows Service and tried to call it from WCF Service but it did not appear in the Intellisense list. Is my assumption correct or is there a way to establish communication between Windows Service and its hosted WCF Service? Thanks. kr

Windows service can't use Reporting Services on SQL Service 2008 R2

Hello. I have a Windows service that run as Local System account. The service uses the Reporting Services ReportService2005.asmx web service. When I have SQL Server 2008 installed, I have no problems and my service is able to browse and create report. After I have installed SQL Server 2008 R2 I get the error "The request failed with HTTP status 401: Unauthorized." when the service tries to use the web service. If I change my service to log on as a user with administrator rights, it is able to use Reposting Services again. What has changes in SQL Server 2008 R2, that doesn't allow the Local System account to use Repoting Services? And is it possible to configure Reporting Services to allow it?   - Per
