Makeing a service that should call a DLL.. When I run it i a Windows form app it works but in the service nothing happens. no error?? Is there some considers that i have to take care of when calling a DLL from a service app?
[Code]...
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.
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?

I call upon your combined intellects. I have a web application with a silverlight app that calls a ria service. The ria service is defined inside the web application and everything else is just dandy.
The issue is this.It is my understanding that in order for the silverlight application to talk and know what the ria service is, you need to add a service reference for that service. The service reference defines the ria service and sets up the connection binding. One of the files it adds is the ServiceReference.ClientConfig which has the connection binding in it. During the course of this application's development, this is the way it was set up. And it worked perfectly fine locally and on the dev server.
Unfortunately there were issues when deploying to the clients in-house server. At this point I was onto other projects while my co-worker continued with the deployment. He soon became frustrated with the goofy errors that were occurring and recruited some help. This dev came in and, albeit got it working, but in order to do so he removed the service reference from the silverlight project but left the ServiceReference.ClientConfig which pointed to the location of the service in the web application(but that's it, no definition or explanation as to what the service does and I'm not sure how the silverlight app is supposed to know how to work with it..). This works perfect on my co-workers workstation and he has deployed this version to the clients server fine.
When I open the project it doesn't run at all. And the reason why is that it doesn't know what the service is that i'm using in code. Specifically, it doesn't know where this is (names changed for clarification):
Imports SilverlightApp.ServiceReference.WebApp.Service
I have cleaned the solution, completely deleted and got the latest from source control, built the web app first and made sure the asp.net dev server was running so that the address in the ServiceReference.ClientConfig resolved correctly. But, alas, it still doesn't know what Imports SilverlightApp.ServiceReference.WebApp.Service is.
So, to get it working on my workstation, I added the ServiceReference back but kept the current connection bindings so that it matched the endpoint in the web app web config. and changed the import statement to Imports SilverlightApp.ServiceReference and everything works fine.
Is it possible in .net 2.0 to enable calling web service only from localhost and to disable calling web service from outside?

I have been given the task of calling a web service which returns an xml data feed which I am doing like so:
For Each r As DataRow in SomeDataTable
Dim msFeed As String = string.format("[URL]?param={0}", r!SOME_VAL)
Dim x As XDocument = XDocument.Load(msFeed)
Next
This is all fine but as you can see x just gets overwritten with every iteration. What I need is create an xDocument and add each feed from my loop but I am unsure how to proceed.
Solution
Dim xAllFeeds As XElement = New XElement("Feeds")
For Each r As DataRow in SomeDataTable
Dim msFeed As String = string.format("[URL]?param={0}", r!SOME_VAL)
Dim x As XDocument = XDocument.Load(msFeed)
xAllFeeds.Add(x.Root)
Next
When I try to call a [Java] web service from .NET, I am getting what appears to be a security credentials issue. CWWSS5509E: A security token whose type is [http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-username-token-profile-1.0#UsernameToken] is required.Is it even picking up the credentials that I am trying to pass? At this point, I just want to make contact with the web service and get access. In my example, ServiceReference1 is a generated Web proxy class.

I'm creating a windows service with a timer that will tick every few seconds and then query a database. The timer for the service works fine, but as soon as I add any of the MySql details it stops working. Just adding the few lines below stops it from working
[Code]...
I'm currently starting work on my first windows service and I've encountered what I find to be a strange error. For some reason the compiler is telling me that a whole bunch of typical classes (such as Image, Bitmap, Graphics, etc) do not exist. For example, these simple lines of code, which work perfectly in a normal project, return a bunch of errors:
Bitmap b = new Bitmap(destWidth, destHeight); //Error 13 The type or namespace name 'Bitmap' could not be found (are you missing a using directive or an assembly reference?)
Graphics g = Graphics.FromImage((Image)b); //Error 17 The type or namespace name 'Image' could not be found (are you missing a using directive or an assembly reference?)

I'm having trouble getting my archive service working. The service counts files in a directory and sends a email. Pretty simple. However, it randomly stops working. I debugged the service and found nothing wrong. I also have it writing to the eventlog so that I can use it to determine where it fails It progresses through each function normally. I thought my program was failing at on point, because it was only posting "Email Notification Service is Running". However, I realized it wasn't posting to the eventlog source so I've been playing around with different ways to post the message to the eventlog. Am I missing something from my code below? I'm really scratching my head with this one.

I am jsut adding bits on to a Windows Service we are making here at our company, its an Asset Management tools with a few built in extras. It runs as a service on everyones machines but we can also do things like request a reboot etc through it.At the moment when We send a Reboot/shutdown etc command to it the Service on the machines calls 'C:WindowsSystem32Shutdown.exe' with the appropiate switches. This displays the windows shutdown warning to the users but nothing they can do about it.
What I was wondering if I create a seperate exe (or even better built into the service but I am not sure if this is possible) instead of the Service Calling 'shutdown.exe' it calls this form up to the user which states that we have requested a reboot etc but there is a 'Cancel' option. The Cancel can just end the form/program and nothing more, if the timeout that we specify is reached then that form/program then calls shutdown exe for an instant shutdown.
I know that the Service runs in a different user Space and we have no telling of who is logged on to that machine so I will need a way to just launch the form to any logged on users. Doesn't matter to much if there is no one logged onto the machine but if it does display this form while noone is logged on that is not a big deal.
I am working on a VS .NET 2008 windows service for 2003, however it doesn�t appear to work correctly.I am basically reading a file from a networked computer and trying to display it�s content, the code is as follows:
Code:
Public Class LB_Analyzer
Private WithEvents Timer1 As New System.Timers.Timer
Protected Overrides Sub OnStart(ByVal args() As String)
[code]....
Now, everytime I run this service it logs the events inside the "GetMachineVol" function, but I never get to the ""Ticked at "" event log from the "main" sub, pretty much as if the service stopped working after trying to assign the value returned from "GetMachineVol" to the string "MachineVolBSFull". I tried using this code on a windows form and everything works fine, and since debugging a service is quite beyond my skills, I really do not know what could be wrong.
I'm having complications with imlementing a service that uses a timer to send emails. In my code, it stops in GetDocuments() after TisValid() validates the directory path. I tried using a addhandler and threading but neither worked.
View 3 Repliesi 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.
We have a windows service running under a network account that calls and runs an ActiveX exe. The exe is running under the local system account, not the network account of the service.
