WCF service to be called from Windows CE

Posted By:      Posted Date: November 29, 2010    Points: 0   Category :WCF
 

Hi

My goal is to have a windows mobile ask a server about a list of products. The server could be behind a firewall, NAT, citrix and who knows what else.

So, to achieve this my current solution is to self host in a windows service as local system. This works in my development environment but probably not in real world scenarios.

I don't want any support calls regarding connection problems, so my current thought is to host the web service on the internet. In that way, I have a windows mobile device and a server that only needs outgoing connections on port 80, which I believe is what a browser does. Now this is fine, but complicates my solution. This means that instead of a simple GetProducts() call, I need some kind of command/polling architecture. This is the point where I am confused as to what is possible with WCF.

What I currently think is like this:

For my device to get its products, it calls the webservice with a getProducts() call. The web service "blocks" the call and holds a state (memory or file?) about object device id and a command id. The server polls every 10 seconds or so and now detects a command id telling him to deliver its products, which it does. The web service receives the products and continues the execution path and returns them.

This surely has to be done in an easier way? All

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.

Trying to get SPSite when called through a web service

  

I have built a custom timer job that makes calls to a web service that I built.  The reason I built the web service is because I recognized that the sharepoint timer job does not have context for a site and I thought that by having the timer job call the web methods of the web service I could have the context that I desire.  This works great for accessing the web.config file, however, I have discovered that I am unable to get SPSite (SPSite oSite = new SPSite(AbsoluteURL)).  The constructor does not throw an error but I am unable to use the new object.  If I am able to get to the web.config and the site is a SharePoint site I figure I should be able to get an SPSite object.

I am trying to understand if I am running into a known scenario or if this should work and that I have a bug that I don't recognize.


WCF Service Function Getting Called Twice

  

Hi,
I have a WCF Web Service.  I am trying to test the service from a web form.  The web form calls the service using WebOperationContext.  The call successfully sends, however the web service function gets called twice while stepping through the code.  Nothing happens in between the first and second function call.  Not even setup of the Service.  The function itself is building a Generic List<Of Type T> and adding objects to the list.  The odd thing that happens, if I do not make the call to the add function, the Service function doesn't get called twice.  I'm including the network log collected from the network layer.  I can provide more source code if need be.  

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

Unable to call an asmx web service using windows authentication from a Service workflow

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

Best Practice for Windows Service "Settings" (Configuration) with .Net (C#) ???

  
Background:   I'm developing a Windows service using C# and .Net 3.5.  The behavior of the service should be controlled by some settings.  The settings will vary per host-computer but will not vary per user (which should be understandable since the settings control behavior of a service.)  A GUI panel of sorts must be provided to set-up and modify the settings that control the service behavior.Secondly, there is a "locally installed application" that has its own settings and those settings also vary per host-computer so all users of that computer would experience the same settings.  (Seemingly analogous maybe to a connection string but not a connection string.)Note that I do NOT perceive any need for Click-once support, web support, and so forth.  Translation:  I think I need the simplest darn type of settings support, the old "dinosaur" level of requirements not much more sophisticated than INI files used to be. I've researched using the "built-in" settings that make use of the Settings Visual Designer in VS 2008 and  System.Configuration.ApplicationSettingsBase.  It seems that: 1.  Application Settings cannot be changed at runtime.  MSFT documentation indicates the software must be shut down and settings must be modified by patching the XML with a text editor (notepad et al.)  The framework specifically prohibits application settings from being
