What Difference Is Between Pausing / Resuming And Stopping / Starting A Service

Aug 25, 2010

I am developing a Windows Service in VB2008 and am in the testing stage. What I have noticed is that if I Pause it while it is busy doing something and then resume it, the process generates an error. While I am debugging this I wanted to determine exactly what the difference is between Pausing/Resuming and Stopping/Starting a service.I searched, but most results simply told me how to Stop/Start/Pause and Resume a service, a hurdle that I jumped over many years ago. Does any one know of any resources that go into detail what happens when a service is stopped vs when it is paused?From some experimentation, it seems that if I do not place any code in the OnPause and OnContinue events the Pause/Resume commands have no effect.

VS 2010 Starting/Stopping Print Spooler (Windows Service)?

Jan 17, 2011

Since the coming of Windows7 at our office we have sometimes the issue that the print spool is crashing.Users don't have admin rights to restart the service so that leaves them only at restarting their computer as solution.Which costs alot of time... As we cannot find a final solution to this problem I've begin to write a small tool so they can restart it..I've only hard code a local admin account in the source for this operate for them..

VS 2008 - Stopping And Starting Timer In Background Worker

Oct 18, 2009

I have a background worker which runs, at the start it stops a timer which has it's interval set to 500ms, at the end of the bgworker sub it starts it again. I've debugged and found out that the line that starts the timer up again (tTimer.Enabled=True) runs. However the timer does not resume. I'm don't know, but I'm thinking perhaps because I'm stopping and starting it on another thread it's not resuming properly or the sub it was attached to (via AddHandler) has been reset or something so it's running but not running the code in the sub it was attached to. If I never stop the timer in the code, it continues to run just fine, but I need it to stop at the start.

Stopping A Windows Service, A Different Service Stops As Well?

Mar 3, 2009

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?

VS 2008 Stopping A Service

Apr 26, 2012

I know the title of this thread is a show stopper for a lot of us . But what I want to do is stop two services from running for a period of time then restart them. I know I can do this from the command prompt by using net stop servicename then restart with net start servicename. I need these two services stopped to do some work on the database. I do this manually right now and want to automate the process. I tried process.start with the command net stop but that did not work out. If I try the Process List I get the process running but not the services.

VS 2010 - Windows Service Stopping Unexpectedly

Jun 4, 2012

I wrote a custom windows service (VB .Net) to run some processing on data files in the background of one of our servers. The service basically finds the next file to process, breaks it apart and makes a PDF or two - nothing super complicated. It utilizes a timer, if a file is not found, it waits a bit and checks again (repeat indefinitely). The service has run for a week or two with no issues/pausing/stopping. I have plenty of error handling for this and I have not been able to break it... until today.

Service Created In VB Not Starting

Aug 24, 2010

We have service developed in Visul Basic .NET. This service utilizes some COM objects provided by SAP to access SAP database. This has been working fine till yesterday. On this Sunday, we upgraded the SAP system, and subsequently all other programs were also re-builded using the new DLL files (for the COM object). We tried doing the same for the service also. But it is not starting now. When started, it shows a message saying service terminated unexpectedly. This is probably due to the fact that it is not able to load the requisite DLL file.

Starting Windows Service As Standard User

Aug 4, 2010

My app (which runs ok as a standard user) requires updates to be installed, but I don't want to have to input the administrator username/password each time nor do I want to increase user privileges to administrator.

I have a windows service which handles the downloading of updates etc (running as Local System) but the start command needs to come from the main app (running as a standard user). This is not permitted and I get Access Denied.

I understand why this is happening but is there an alternative way to achieve this? I want to handle program updates as the standard user without using ClickOnce or installing to a non Program Files folder.

VS 2008 Starting A Custom Windows Service?

I've created a Windows Service and installed it via InstallUtil so I can test it out.The installation goes seamlessly, but it will not start from some reason. When I attempt to start it, I get an "Access Denied" error and that's it.

I haven't been able to find any information via the normal channels.I first thought to give the service admin rights, but that didn't work either.

Windows Service To Monitor Programs Starting

Jan 14, 2009

I am trying to create a windows service that sits in the background waiting for programs to be started. When the programs start I want to be able to check a unique bit of information for each program (I believe GUIDs may provide this) to see what the program is. If the program is not allowed, I aim to provide a warning to the user and possibly close the program. The aim of the application is to identify when users are attempting to install additional software on to the computer so simply monitoring for a certain executable wouldn't work as msiexec is called for all MSI's and as I only want to stop blacklisted programs...this wouldn't work.

VS 2008 : Resuming A Countdown?

Dec 5, 2009

I'm trying to add a new feature to some software I have developed but am having difficulty. Essentially I want to add a 'Pause' and a 'Resume' feature.I have a timer which counts down.

Private Sub Timer_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer.Tick
Dim togo As TimeSpan = mTestEnd.Subtract(Now)
If togo.Ticks < 0 Then
Timer.Enabled = False

[code]....

When the Start command button is clicked the timer starts counting down from what amount the user inputed. I've added an elseif to pause the timer and this works ok. When I click resume the although the timer text has paused the actual timer has not and continues from where the timer would be if it had not been stopped. Much like a stopwatch lap timer. Could you help me with my Else statement.

If StartButton.Text = "Start" Then
StartTime.Text = Format(DateTime.Now, "HH:mm:ss") 'Hour(Now) & ":" & Minute(Now) & ":" & Second(Now)
txtTimeLimit.Text = HourUp.Text & ":" & MinuteUp.Text & ":" & "0"
mTestEnd = Now.Add(TimeSpan.Parse(txtTimeLimit.Text))

Forms :: Resuming A Thread After AbortReset?

Nov 4, 2011

I am trying to find a way to resume a thread after catching the AbortThreadException and calling AbortReset.

My thread is running a loop to control two motors used in a raster scan. Once the button is pressed to begin the scan, I want to be able to click a stop scan button and have the following happen:

1. AbortThreadException is thrown and caught- a window comes up asking if you really want to abort the scan. Click yes for abort, no for suspend, or cancel to continue scanning.

2. Given users answer the program responds accordingly- If cancel, then the scan should continue right where it left off and not restart.

My problem occurs in my understanding of the thread events. I am not sure how to tell a thread to wait for a button event nor do i know how to tell a thread to continue where it left off. I also noticed that the 'suspend' and 'resume' methods have been deemed obsolete and i am not sure of the alternative way of doing those actions.

The following is the code used to catch the exception and execute the task.

.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.
