C# - .NET Windows Service - Architectural Decisions?
Aug 18, 2010
I currently have a Windows Service which continually runs throughout the day. It has multiple threads which kick off:tasks daily to update cache tasks weekly to do cleanup 24/7 task to import XML into SQL Server tasks which run for around 12 hours per day kicking off a console application to manage ETL The tasks are not the important part of this question but it gives you the idea that this Windows service has grown to be a monster. It manages the imports of somewhere in the region of 300 million records per day.It is hectic, but it works.
This iteration of development is giving me a chance to review the service and possibly break it down so that it is more manageable. It is thought that this could be multiple services with one manager service - ideal if a component needs to be updated then the whole thing does not need to grind to a hault.
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.
i have an exit tool strip that asks if you want to save your data. If the user clicks no then it closes the form, or if the user clicks save it saves the data and closes the form otherwise it does not close. What i'm running into is how to account for both a yes or no answer. The current way i'm doing it pops up a second message box if the user clicks no.[code]
I am trying to communicate with a Windows service on a remote machine on the network but i keep getting an exception saying the following: "System.InvalidOperationException: Cannot open Service Control Manager on computer 'machine001'. This operation might require other priviledges. ---> System.ComponentModel.Win32Exception: Access is denied.
Is it possible to have a dotnet windows service which monitor other services and upon stop of any service, the monitoring service would be able to start the stopped service.
In the past I had the indexing service installed on a Windows Server 2003 and used it to index files for my website. I did this by executing an OleDbCommand with a query and a connection string.How do I accomplish the same thing with the new "Windows Search Service" (Windows Server 2008) by using VB.NET? Does this work the same way so that I only need to change the Provider name which has been "MSIDXS.1" up to now? Case true, what is the new Provider name?
We have a server with multiple services written in .Net 1.1 and 3.5 running on a Win 2003 server. Everything runs fine, but when we stop a certain service, an unrelated service stops. I have checked and neither has any dependencies. The service we stop is in 3.5, and the unrelated service that incorrectly stops is in 1.1. We get no error messages, nor event log errors, so we are baffled.Does anyone have an idea as to what may be causing this?
I am using a windows service and tried to copy some file as below,System.IO.File.Copy("Z:abc.txt", "C:helloworld.txt")Note: Z: is a map drive from another host in 1 LAN (same LAN)I got error, "Could not find a part of the path 'Z:abc.txt'."But when I tried it at a simple application using windows application, it works with the same code as above.
Tried to write my first Windoes Service yesterday with a certain degree of success but I couldnt install it.Upon running teh Install programme in the command line I was presented with a 'Set Service Login' window with a User ID, Password and Confirm Password text box.I attempted to use my windows login credentials but the install failed and was rolled back.Im using a computer on a company network with Win2k?
I've created a windows service and started a deployment project for it. I have the project installer class in the service project and I've added the "Standard output etc.." from the service project as custom actions for the Deployment Project. When I attempt to install it, I get the error "Specified service already exists", which shouldn't happen (even though the service does exist) because the installer should be removing the old service and installing the new one.
I've checked that the versions are different, and that the Product Code is also different, also RemovePreviousVersions is set to true. Can anyone tell me why it isn't uninstalling my old service when I update then install again? .S: MODS: DO NOT MARK MY POST AS ANSWERED, IT IS RUDE, YOU HAVE NO IDEA IF YOU'VE ANSWERED MY QUESTION!Sorry, it gets ignored in my signature.Mods
I have a .net Windows Service developed in VB.net. I have a settings file in the root directory called Connections.XML and I am setting the basedirectory [code]...
When I schedule the service this is working absolutely fine in my Windows XP machine. But when I installed the same service in our development server (Windows 2003 64 bit Server) for some reason it is not able to locate this file.
It is possible to create windows service using windows form control in vb.net. give me the url or links. The windows forms control such as, Timer control, list-box, notify-icon control etc.
I'm porting code that I wrote for use in a Windows Forms application to a Windows Service, but for some reason, the code that worked in the Windows Forms application is now throwing errors in the Service
I have developed a Windows Service in VB.Net (VS2010) which is running on Windows7. I am trying to get "MainWindowTitle" for processes thru their process object but it returns empty.
I'm writing a windows service (MacTimeFix.exe) to fix the Windows time on a Macintosh (it's like this: i live in Moscow (GMT+03:00), and Mac OS thinks that the system time is GMT+00:00 and adds 03:00 to it< and Windows thinks that system time is the local time).I need to execute my code when my VB app is closed. (it happens with the shutdown of Windows) The form is invisible (hidden), and the user mustn't click anything except windws shutdown button. It is a service. When i write a Form1_FormClosing sub, it works only on Alt+F4 or CloseButton and doesn't work when the app is stopped from Windows Task Manager or whatever also.I need a way to execute sub when app is closed with taskkill (without /force) or a way to execute a several app on Winshutdown.
Here is my code:
Public Class Form1 Dim SystemMary As String Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Me.Load SystemMary = Mid(TimeString, 1, 2)
It is possible to create windows service using windows form control in vb.net. The windows forms control such as, Timer control, list-box, notify-icon control etc.
I'm printing pdf files via the below code in a service. In Windows 7 this works really well, In Windows Vista, nothing happens at all? What am I doing wrong?
I am working on a .NET Windows Service where I am trying to store settings that will be used when the service is started and while it is running. I have searched through posts on SO and found that using the Settings in the properties of the project is great for use with console and winforms applications. However, Google and SO are silent when it pertains to storing these settings with a windows service.
Is there a way in which I could invoke a windows form from a particular windows service....??
Have created a windows service, installed it and everything is working fine... Now I want to design another windows form that I would call from the service while running it I know that with the help of ServiceController class we could interact with windows service from a windows application but am not sure of the other way round implementation....
Is there a way to basically merge a Windows Forms Application with a Windows Service Application and allow the passing of parameters on start up to determine if it should start the standard GUI or launch as a system service
is it possible to take and run vb.net windows application setup as windows service...if possible means how to take and run vb.net windows application setup as windows service....is it possible to run the vb.net windows application setup automatically 5 mins once....if possible means...how to run vb.net windows application setup automatically...want to run 5 minutes once automatically..
The first one is rather confusing for us. We have a windows service that cannot connect to our web service, from within an external network. But we also have a GUI application for testing the connection prior to the Service starting that connects and sends us the required data. The GUI is used for entering proxy information that the windows service will also use to connect. We have several installs where the gui app uses the proxy creds to connect and does so o.k. but the windows service cannot connect using the same credentials. We do not get a 407 error most of the time. We are receiving the server failed to respond message.
I have an application written in vb.net 2008, and I want to convert this to a windows service. It does have an interface, but only to start/stop the application timer, and display a log.
I have created a windows service in VB in visual studio 2008. The purpose of this service is to copy files from one network drive to the UNC path for a sharepoint file location. It works properly on a Windows XP machine, however when I installed it on Windows 7, I am now getting Access Denied error messages. In troubleshooting, I tried to simplify things to see if I can see the directory that I'm trying to write to, and the System.IO.Directory.Exists is returning false. I am able to see other netowrk shared drives, just not this particular one, and it appears to only be an issue from my Windows 7 machine, as I can do this with a Windows XP box.
I have also tested this code in a Windows forms application and it will work as expected. It appears only when I move to the service.
