Make An Application A Managable Service?

Feb 18, 2011

I made a client/server application and I want the server application to be a service that can have it's setting managed through a GUI.I know how to make an application a service, but how would I give it the ability to have its settings changed and start/stopped through GUI?Or would you just make a program that can edit a certain server's config files and just restart it to pick up the changes?

.net - WCF Service Hosted In A Managed Windows Service Connect Using A WCF Service Application

Jul 14, 2011

i have a Windows service that is hosting a WCF service through net.tcp and this is working great. I have also created a WCF service application. I am trying to add the net.tcp service reference to the service application. Then I add it to the GAC that goes ok but if I try to RegAsm the WCF service application to allow it to be called from Server.CreateObject I get the error:

Warning: Type library exporter encountered a type that derives from a
generic class and is not marked as
[ClassInterface(ClassInterfaceType.None)]. Class interfaces cannot be
exposed for such types. Consider marking the type with
[ClassInterface(ClassInterfaceType.None)] and exposing an explicit
interface as the default interface to COM using the
ComDefaultInterface attribute.

It does not work. I have tried to call it through a class library but this does not work either as the end point is not set correctly.

Service Reference Stops Working When Make Changes To WCF Service?

May 26, 2011

I'm using Visual Studio 2010 and .NET3.5. I've created a WCF service application. I'm including two DLLs that contain the types I'm returning. The first method I wrote works both in WCF Test Client and also in a console application I created to test. When I move on to the next method that returns a generic list of a type. It works great in WCF Test Client, but when I update the service reference it acts as if the service is unavailable. All my objects say can't find reference, and I can no longer see it in the object browser. It's like it just disappears. I can still see it in the Service Reference folder. If I go back to the WCF app and comment out the contract and implementation of that one method it work again. I created a local class very similar to the class I'm using from the dll, and the it works. Is there something I'm missing here? Can someone point me in the right direction?

.NET Application Receiving 503 Service Unavailable Error When Calling Web Service?

Apr 28, 2009

This is a bit of unusual problem that I'm experiencing, but recently one of the users of a production application started reporting errors in the system. These were traced to a 503 Service Unavailable error when making a call to a web service used by the application.

Now here's the odd part, only the one user is affected by this issue. Other users of the application have not reported any errors. When the user logged on to a different machine that worked for another user, they still received the error.

Make Web Service App?

Feb 6, 2009

My employer has an in-house windows order-entry application which Ive written in VB6. I've taken a section of the VB code and made a stand-alone .exe that I can pass a parameter string to and get a different parameter solution string back. I put the stand-alone exe on the server and can access it from the app on my pc. It is all working fine for our windows needs.

Now my employer wants the stand-alone exe converted to a web service so it will work with our windows app plus our UNIX order-entry app. Both apps would be passing the same parameters to the web service and be able to use the same solution string coming back from the service. Does this sound doable?

[2008] Make Web Service Ports?

Feb 2, 2009

I'm making an application that tracks jobs we log in our IT department and as I'm often out and about it would be handy to be able to use this app from my laptop and connect in to our server at our office. The problem is that a lot of the places I go block all outboundtraffic apart from port 80 and 443 (for HTTP and HTTPS). Now I know I could write an ASP.NET front end that I could just access over the internet but to be honest I just plain dont like making ASP.NET web pages and so if there is any way I could do this just through my standard desktop app that would be good.

I've heard a bit about "web services" and to me this sounds like a solution but I dont know enough about them to decide if I should use one or not.The main thing that will decide this is whether or not I can make this web service listen on port 80, is that possible?Also, is it hard work making something use HTTPS instead of HTTP so that the data is encrypted? I mean, do you have to do all of the encrypting yourself or is there some sort of automatic function you can use to handle this?

Use A Web Service Within A Windows Application?

Jul 14, 2009

I created a very simple web service on my godaddy shared hosting web site, using VWD. I wrote a VB app to use some web services. I added a web reference to another web service with no problem. But I could not add a web reference to MY OWN web service. It was blocked by a Discovery Credential dialog that could not succeed. After days of communication with godaddy tech support they stated it could not be done (for security reasons).

Webcam Application As Service

Jun 30, 2009

I have created a webcam application. It uses a PictureBox to display the image and saves the image to file via the clipboard. I've used code found on this forum and all works fine.

What I'd like to do now is to convert the application into a service.

I know how to create a service, but does the webcam image have to actually appear on the screen to save the image? My goal is not to have any forms display on screen, therefore conforming to typical service operation.

How To Make A Windows Service Work Properly

Aug 3, 2010

My project requires that a windows service checks up a table on a sql database(MDF) and if product existence is 0 then sends an email to some mail address and keep checking every 24 hrs.Now Im able to send mail messages but what Im not able is to make the service itself to work or at least make sure that is working.I do the following(correct me if I do something wrong or missing a step):

1. create a new project and choose windows service

2. add a timer and set to 4000 ms just to test not wait the 24 hrs lol

3. then open its event timer_elapsed and put some code on it, like a msgbox that would keep spamming every 4 secs just to test

4. at the event onstart I enable the timer by: timer1.enabled=true

5. at the event onstop I disable the timer by: timer1.enabled=false

6. right click then choose add installer

7. in the newer installed with the two objects:

a. serviceinstaller1 set its properties to: displayname: myservice and servicename: myservice

b. serviceprocessinstaller1 set account property to LocalSystem

8. build the project and install it by opening the VS console and type: "installutil c:path blah blahservice.exe" then hit enter

9. all successfull installed open the pc manager and run the service from the list and this should be the deal

Now my real problem is that by following those steps my service is sucessfully builded, installed, and started but after the 4 seconds no msg pops up so this leads me to think that is not doing anything or I did something wrong in the steps above. Is there another way to test if this service is working else than the msgbox or the log entry? Plus, Im working on my home pc which is a xp OS. I tried the same at college pcs wich are win7 and when I did install by the console it returned an error weird but in my home pc it doesnt(and I have to present my project at college at college and tomorrow

Make A Windows Service Terminate A Process?

Jul 25, 2011

I am working on a Windows Service project that is supposed to start automatically with Windows and it has a timer to check if a certain process is created (in this case "iexplorer") the service should terminate that process. In addition, the user should not be able to stop the windows service.

I was able to create the process and make start with Windows. I changed the property (CanStop) to False but that did not help because after a few tries the servise stops. I used a For-Next loop in the timer to check for the process to terminate but unfortunatly, it didn't work. The code I used is:

Dim theProcesses() As Process = System.Diagnostics.Process.GetProcessesByName("Iexplore")
For Each currentProcess As Process In theProcesses

VS 2008 .NET Windows Service : How To Make It Work

i have written hundreds of programs with vb.net 2008, but never a service before. I have a simple service written that basically just rights a entry in the eventlog to test. No coding/compiling issues. I run the "installutil.exe" and I get a error ever time. So I went back and added the "Add Installer". But I am sure of what else I need to do, as I get the same error. Please assist.

I think the OnStart method have never fired otherwise the visual studio will popup once the debugger.launch line is executed even I tried to write some text to the event viewer to make sure but nothing gets written to the events viewer after I started the service. I included also the debugging symbol in my windows service setup project but I end up with the same result.Why it's not working? How can I make sure that the OnStart method gets fired or not?
