Windows Services, Timers & Threading

I have a self hosted WCF service. I have 2 methods that need to run periodically so the Host Service has 2 System.Threading.Timers.
Timer1 has a long running process. May take up to a minute to run.
Timer2 has a method that is quick but MUST run every 10 seconds.
My first thought was that each timer would run on a separate thread and I should be able to get this right out of the box. I was incorrect. I can't get Timer2 to be consistent because there seems to be a dependency between the two timers
and/or the server load. Timer2 doesn't give me a clean execution pattern.
In trying to fix this, I put a System.Threading.Tasks.Task around the method call on Timer1. I expected this to release resources so that Timer2 can run cleanly. Still, no luck.
This has me stumped. Any idea why Timer2 doesn't fire on a consistent pattern?
Thanks for your help, Joel.

Timer2 has a method that is quick but MUST run every 10 seconds.
Timer2 doesn't give me a clean execution pattern.
Hi Joel. What doe you mean by clean execution pattern? Is the timer taking longer than 10 seconds to execute the callback or is it random when the call back happens based on server load?
What I can tell you is that any thread execution is always dependent on the O/S. If the O/S is busy with a process dubbed as high priority which takes up all the resources then your application would also suffer as would any other application running on
that server. This could be seen in the form of threads not being allocated to run your application, timers not being fired, longer wait times than usual for resource requests etc.
As stated above if thread 1 is doing some heavy lifting and using up more CPU cycles/resources on the O/S is willing to allocate to your process then thread 1 (example of processing started on timer1) could affect thread 2 (example of processing
started on timer 2).
As far as timers go the timer is System.Threading namespace will always execute independent of each other unless you have added syncronization logic or thread 1 (example of processing started on timer1) blocks on a resource thread 2 (example
of processing started on timer 2) is requesting.
Let me know if I am way off on what I think you are asking here.

How to get a Thread Dump from Windows Service?

We're running WLS 8.1 as a Windows Service, but we can't seem to generate a Thread Dump when the server locks up (apparently).
Can anybody recommend a wrapper that will do this?
--Kurt

Hi,
Please refer to the following URL for more information http://e-docs.bea.com/wls/docs81/adminguide/winservice.html
To cause the WebLogic Server instance to print a thread dump to standard out, do either of the following:
Use the weblogic.Admin THREAD_DUMP command. For more information, refer to "THREAD_DUMP" in the WebLogic Server Command Reference.
Open a command prompt and enter the following command:
WL_HOME\bin\beasvc -dump -svcname:service-name
where WL_HOME is the directory in which you installed WebLogic Server and
service-name is the Windows service that is running a server instance.
For example:
D:\bea\weblogic81\server\bin\beasvc -dump -svcname:mydomain_myserver
Cheers

Different thread/memory limits when running Java via Windows Service?

My company is developing a Java application that employs a "black-box" interface, which generates several memory-intensive threads. When we run the application via a batch file, the threads seem to run in parallel on a quad-core server. However, when we install the application as a Windows Service on the same server, it appears that we hit a hard limit of 35 threads, and the process pegs out one of the server's CPU's at 100%. Does anyone know why we don't see the parallelism when we run it as a Windows Service? Does anyone know if Windows imposes different memory or thread restrictions on services, as opposed to normal desktop applications?

Windows service write to event log

Have strange conduct of code within my application. I've created windows service the same as according to MSDN default instruction:
https://msdn.microso...=vs.110%29.aspx
its working and logging to event log correctly. After that i copied that project and based on it i started to create second one almost similar one. my issue is within below part of code belongs to ProjectInstaller.vb when i installed it and tried to Start i
get message that Windows service started and stoped imedietly.
Imports System.ComponentModel
Imports System.Configuration.Install
Public Class ProjectInstaller
Public Sub New()
MyBase.New()
'This call is required by the Component Designer.
InitializeComponent()
'Add initialization code after the call to InitializeComponent
End Sub
Protected Overrides Sub OnBeforeInstall(ByVal savedState As IDictionary)
Dim parameter As String = "MySvcDeon2"" ""MyLogFileSvcDeon2"
Context.Parameters("assemblypath") = """" + Context.Parameters("assemblypath") + """ """ + parameter + """"
MyBase.OnBeforeInstall(savedState)
End Sub
End Class
Within this line: Dim parameter As String = "MySvcDeon2"" ""MyLogFileSvcDeon2"
When i change it to this form then service its starting correctly without any error meassage:
Dim parameter As String = "MySvcDeon1"" ""MyLogFileSvcDeon1"
its working. But Deon2 is already created by my first windows service. Whats wrong?

i also tried from official msdn site but same error, anyhow, see my code below:

Call a program via windows service

Hi! I have write a windows service,and it works. I want to call a .exe file,and my .exe file is signature. The program can not work when I call it through my service. How can I solve my problem? Thanks!

Hi Hassan,
Thank you for sharing the code with us!
As I understand it, your code handles the situation of an user that is already logged on to an interactive window station (those of you, who need to create a UI-process of a user not yet logged on, could use
CreateProcessWithLogon, or
LogonUser to get the token). Because calling CreateProcessAsUser() requires advanced privileges (such as "Replace a process token level", or "Act as part of the operating system", privileges usually not held by a user unless specified so by the security
policy), the code also implies a service running in the local system account (or equivalent).
To make it easier to read, I'll post here the C#-version of your code:

To use the code, create a new windows service project, and add code like the following one:
using System;
using System.Diagnostics;
using System.ServiceProcess;
using System.Timers;
namespace WindowsServiceLaunchingExe
public partial class ExeLauncherSvc : ServiceBase
public ExeLauncherSvc() {
InitializeComponent();
Timer timer;
protected override void OnStart(string[] args) {
timer = new Timer(5000);
timer.Elapsed += (sender, e) => {
try {
timer.Stop();
EventLog.WriteEntry("WindowsServiceLaunchingExe", "Launching process...");
NativeMethods.LaunchProcess(@"C:\Windows\notepad.exe");
} catch (Exception ex) {
EventLog.WriteEntry("WindowsServiceLaunchingExe", ex.Message);
timer.Start();
protected override void OnStop() {
Because NativeMethods.LaunchProcess() throws exceptions on errors, be sure to enclose calling code in a try/catch-block.
I also would recommend reading this:

How create Windows Services in Azure using Visual Studio 2012

Hi,
I have a need to write a Windows Service (Batch Job), which would execute everyday at a specified time, say 4:00AM. This job will do some processing and will send out an email to predefined users. I am using Visual Studio 2012 for the development.
Based on some research, it looks like that Azure doesn't have a concept of Windows Service. Rather, we need to create WorkerRole to achieve the same.
I wrote the code to implement the WorkerRole. The problem, I am facing is that
1. How to prevent the continuous looping of the code below? I want the task to be executed only once a day at 4:00AM
2. How do I schedule this functionality in Azure?
Any help will be highly appreciated. I have provided the code sample below.
Thanks.
   public class WorkerRole : RoleEntryPoint
        public override void Run()
            while (true)
                SendNewsEmail();
                Thread.Sleep(10000);
       private void SendNewsEmail()
            /*Email Logic Goes Here*/
        public override bool OnStart()
            // Set the maximum number of concurrent connections
            ServicePointManager.DefaultConnectionLimit = 12;
            return base.OnStart();

HI
I think JuneT's answer is what you want.
However it's for Azure website.
If you still want to use a workerRole, you need much harder work.
You can use Timers Class to do such things:
http://stick2basic.wordpress.com/2013/02/22/how-to-schedule-a-c-windows-service-to-run-a-method-daily/
How do I schedule this functionality in Azure
I suggest you save the settings file in a cloud table, and notify your webrole using WCF service to let the service get the new settings when your changed it.

How to create a client console to connect to server in windows service using c#

my code is error
can you check the code please
client console code
partial class Program : ServiceBase
public static void Main(string[] args)
serverservice ss = new serverservice();
ss.myserver();
TcpClient tcpc = new TcpClient();
Console.WriteLine("connecting.......");
tcpc.Connect("10.128.1.116", 80);
Console.WriteLine("connected........");
Console.Write("enter msg to be transimitt");
string str = Console.ReadLine();
Stream stm = tcpc.GetStream();
ASCIIEncoding asc = new ASCIIEncoding();
byte[] ba = asc.GetBytes(str);
Console.WriteLine("transmitting..........");

byte[] bb = new byte[100];
int k = stm.Read(bb, 0, 100);

Permissions for Windows Service on Server

Post Author: bdimon
CA Forum: Authentication
I wrote a Windows service running as an Active Directory user. It cannot print on the Windows Server so I wrote a windows application to test the permissions. When a user with local admin rights runs the test application, it prints. He starts the program using the "Run As" option and enters the Active Directory user from the service, he gets the same error as the Windows Service gets. This must be permissions-based.
When I installed this Windows Service on a staging server, everything was fine. However the staging server was not "secured" by the network team so the Active Directory user had Read/Execute permissions on the C: drive. I do not want to ask for these permissions on the production server's C: drive.
The error is:
System.Exception: Load report failed. ---> System.Runtime.InteropServices.COMException (0x800002AD): Error in File UNKNOWN.RPT:
The request could not be submitted for background processing.

I believe I'm having a similar problem, and was hoping to see if either you have found an answer to the problem or reactivate this thread in hopes someone will finally answer us.I'm creating reports using a windows service as well. The report files are compiled into the DLL, and they are being exported to save them to disk.   The error is being generated when the report object is first accessed (which happens to be when attempting to set the Text property on a TextObject). It works fine on my development machine. I've installed the service on the production server using a Visual Studio 2005 Setup and Deployment project. I added the 2005 Crystal merge module to the setup, so all necessary files should exist on the server. The service is running as a domain user that has admin rights on the local machine, but we're still getting this error that seems, according to posts I've found online, to be a permissions issue.Here is the exception in its entirety:
Exception Type:
System.Exception

How to launch an application with elevated administrator account privilege from windows service even if the account has not yet logon

Here is the case:
OS environment: Windows 7
There are two user accounts in my system, standard user "S" and administrator account "A", and there is a windows service running with "Local System" privilege.

I passed in username and password of account "A" to method "LaunchAppWithElevatedPrivilege", and also the application i want to launch, e.g. "C:\windows\regedit.exe", but when i run the service program, i found it do launch
"regedit.exe" with elevated account "A", but the content of regedit.exe is pure back. screenshot as below:
Can anyone help me on this?

You code is not dealing with the DACL access to Winsta0\Default. Only the LocalSystem account will have full access and the interactively logged on user which is why regedit is not displaying properly. You'll need to grant access to your user.
You also need to deal with UAC since that code is going to give you a non-elevated token via LogonUser(). You need to get the full token via a call to GetTokenInformation() + TokenLinkedToken.

Hi,
If you see your logs, you server has actually started in "RUNNING" mode. Its only throwing lot of "ClassNotFoundException" because I guess they classes are not available in classpaths. If you know the "jar" which contains which are being complained, copy the jar files to "DOMAIN_HOME/lib" which is simple way to add jars to classpath.

Problems with ShutdownHook and Windows Service

Hi friends,
I am facing a problem with the ShutdownHook when a Java program is run as a Windows Service. In the program I am having a Daemon Thread which will be run in an infinite while loop accoridng to a boolean variable. I have a shutdown hook also which sets the boolean variable so that the Daemon Thread will be stopped gracefully. When i am using Ctrl-C the shutdown Hook is started and the Thread is stopped gracefully.
Later i have made my program as a Windows Service using a utility Java Service Wrapper. But when i stop the service though the Services Window the ShutdownHook is not getting called. I was not able to fnd out why it is happening like that.
Any help will be highly appreciated. Thanks in advance.

Hi Drmetz
If you are waiting on a reply it could be some time, as this is the *Mac OS X v10.3 & earlier* forum and few here know about Windows, parallels MacBooks or the Tiger OS.
Mac's cover a wide field.
You could try reposting in this forum which would be your best best I think.

Windows Service Manager 32-Bit Has Stopped Responding/iPod not showing up in iTunes

Hello,
I've scoured this forum for answers but I cannot find any result that works. I have an iPod classic that I've connected to my Gateway running Windows Vista for over four years without issue. When I was using iTunes 9 the other day, I plugged my iPod into my computer, but it only connected to My Computer and didn't connect to iTunes and update my iPod accordingly. So, the iPod is charging and the iPod is showing the "Connected, Eject before disconnecting" screen, but it isn't adding new music (which kind of defeats the purpose of buying new music). I thought it was because I was using 9, so I downloaded iTunes 10, but the issue still popped up.
This hasn't pop up today after I installed 10, but back when I was using iTunes 9 the following error came up on my computer: "Windows Service Manager 32-bit Has Stopped Working." Now, no error messages pop up, even though the problem persists.
I've tried suggestions in this post as well as in this post. Also, with the fix being recommended in those threads to change the code in Notepad by clicking "edit" under the System tab under My Computer? There's one problem - there is no edit button on my options. I've included a screen grab to prove this.
I don't know if the relative age of the discussions makes any difference - maybe a new fix has com up and i'm just not finding it? Plus, since this issue began with iTunes 9, I can't help but feel like getting rid of iTunes 10 is going to help the issue, either.
This is incredibly frustrating, not being able to add new music to my iPod, so if anyone can help me out, I would greatly appreciate it, as previously recommended ones aren't useful.
Screen grab of iPod connecting to My Computer, but not iTunes:
Screen grab of the lack of an "Edit" button in the place to edit codes as recommended in previous topics:

Windows Service no longer able to print PDF files using Adobe Reader 11.0.07.79

We have a Windows Service that watches a folder for PDF files to be deposited. Once awakened, it executes the Adobe Reader in command line mode to print the PDF files to secure check printers. The Windows Service was working fine with 11.0.06.70 but no longer works with 11.0.07.79.
There are no event viewer errors or errors returned to our Process.Start() call. The Windows Service is running under the identify of an administrator account and has explicit full access to the printer. We have also tried the local computer's Administrator account as well as the default Local Service, but none work.
Using ProcMon to examine the failure, it showed Adobe Reader making many successful registry and file accesses. Adobe Reader then creates a new process, another instance of itself to read in the PDF file and print to the printer. However, ProcMon only shows Adobe Reader accessing AcroRd32.exe, syswow.dll (sp) and ntdll.dll and then the thread and process immediately exits with an exit code of 0 (no file or registry accesses). So, something is causing the instantiated process to fail immediately.
After more research and trying many things, we disabled "Enable Protected Mode at Startup". This enabled things to work again.
We are concerned that disabling this feature might expose security concerns for our customers.
We are suspecting that some security concerns were tightened with 11.0.07.79 that has inadvertently caused printing from Windows Services to falsely be identified as security violations. Can you please investigate and provide a resolution?
Thank you.

Hi,
Can you please give the following details:
1) Command (given in command line)used to print PDF files?
2) Is the issue reproducible with other printers as well?
3) Is directly printing the PDF from that folder using command line i.e without using windows service works fine or not?
Thanks,

Windows Service (SMB) does not start automatically

I have a client with an Xserve G5 running 10.4.8 with all software updates applied. Recently, the client decided to buy a new Ricoh multi-function printer, copier, fax machine. We've configured a share point on the server that the Ricoh uses to deposit the incoming faxes and scans. It works fine, but the downside is that it only works over SMB or FTP. I went with SMB (Windows Sharing) because of Apple's flakey implementation of FTP over the years.
The problem is that when the server gets rebooted -- due to power outtage, software update, whatever -- the Windows sharing does not turn itself on like all of the services do. I have to go into Server Admin and turn on Windows sharing manually.
Is there any way to get the Windows Sharing to turn on automatically at boot up like all of the other services do?

I had the exact same problem after applying the 10.4.8 combo update. This thread solved my problem:
http://discussions.apple.com/thread.jspa?messageID=2962778&#2962778
In short, I had to disable the "Workgroup Master Browser" setting in Server Admin > Windows Service > Settings > Advanced. This is enabled by default, by the way.
