Aspalliance windows service

Let me know for your queries and suggestions. Well written, straight to the point. The illustrations help a lot. I was able to write a working service in less than 15 minutes using this article.

Keep up the good work. Just an FYI. I learn more about windows service with this article. The program will probably run an a single machine but I need to way to allow any user that logs on to access the underlying database. I have heard that I could implement this feature through a windows service and use remoting.

Could anyone give me a head start on this issue? Title: service fire event once Name: henry Date: PM Comment: window service project fire event once.

This application is already developed and it worked fine until we stopped it few days back and when we restarted the application it is not populating the SQL tables eventhough the application is running. I can send you the code if you would like to have a look at it. Please help me. Title: Great Article!!!! Name: madhu Date: AM Comment: Hi Abhishek, This is a wonderful article,I am new to windows service applciations and for the last week or so I am breaking my head to run an applciation which stopped working even though the service is running.

I will try the tips and suggestions made in this article and see if it works. Anyways thanks for the great article. Enter this as class variables Paricularly the bit about the setup project. Until I saw this it was nothing but CMD windows for me.

In my case everything was normal. Still if you want then you can send me your service source and setup project if it is not your company project to me, which i can use for test. Title: Reply to: How do we edit and redeploy? I assume that it's an instance of my process that's still running, but why is it there when I've uninstalled? And how to kill it?

Do you mean, process means. Title: How do we edit and redeploy? I've configured the service to initiate it manually, so before uninstall I stop it manually. Then the steps I follow are: build code, build setup project, install setup, init service through the services console, attach the process to the debugger, stop the debugger when I finish, stop the service through the services console, uninstall the service.

As I said before, after these steps I can re-run the services again, so I don't really have a problem with the service. But I'm worried about this process that keeps running "forever". Title: Reply To: How do we edit and redeploy? I wonder if you are getting some different issue. In your case check the status of service whether it has gone to "Disabled". If so than you may to manually remove it.. Let me know if anything else.

Title: eply on : How do we edit and redeploy? I think the problem with service uninstallation is not a big problem actually. What you need to do after uninstallation of service is - EITHER refresh the service console window then you will see service will disappear OR close the service console window before trying to install service in fresh.

I believe this a minor bug left by Windows. If you keep console window it doesn't automatically removes that service from the list. Hope it will help you.

I think I've done nearly the same things. I've installed the windows service through the IDE, run it through the services console, debugged it, stopeed the debugger and then uninstalled de service through the IDE. I first thought that the service was still running because I've put a Thread.

Sleep instruction, but after restarting the workstation it's still running. And if I try to kill the proccess through the tasks administrator it "ignores" me it seems like if the process automatically restarts after killing.

Title: Reply on : How do we edit and redeploy? Then I shut down the IDE. The Service turns up in the Services console. I start the service and it runs, writing out the lines of text to the text file. I right click the setup project and choose "Uninstall". It appears to execute this process successfully, but if I open the Wondows Services console again, I see that the service is still there, albeit not running. Just to be ultra careful, I restart the workstation, just in case.

But the service is still installed. I open the solution in the IDE again and attempt to uninstall the service again, but I get the error message: "This action is only valid for products that are currently installed. Or Maybe I am being stupid.

Experience suggests the former. If anyone has a clue what is going wrong here I should be most grateful to know. I have just found this link, which identifies the scenario. Incidentally, when the service ran, it worked for a few hours and then stoipped writing to the file. I think this might be another issue with he code. My strong suggestion would be : Always uninstall the service with the same setup used to install the service, then only you should update the setup.

Most of the time you can not uninstall the service with the setup which got updated with modified code in service. I think you got the answer. Title: Reply on: Code stops executing but service is still running Name: Abhishek Singh Author Date: AM Comment: Craig, I think you need to check your db connection and datareader type of object used in the code properly. Check if you are closing connection and datareader in each call, if you are initializing in the trigger function itself.

I think i need to see your code to determine the exact reason. This is a nice Article to get started with Windows Services. I wanted to change the operation of this service so that it appends a vbNewLine at the end of the message that it writes to the text file. It's easy enough to change the source and rebuild, but how to redeploy this change? I tried to Uninstall and re-install from the IDE but this resulted in a message saying that I was not allowed to install an already-installed service.

Nor could I find a way to delete the service from the Services Manager. This must be Kindergarten stuff but this baby service coder ain't gettng it.

Title: Code stops executing but service is still running Name: Craig Date: PM Comment: I had no issue copying your code in this article and getting a service up and running. However, once I changed the code to do some other database related tasks, it randomly stops executing. The odd part is, the serivce is not stopping? The code will run anywhere from 10 to 20 times and then just stops executing? I have tried adding break points on the code as oulined in the article and there are no logic errors in the code itself.

Anyone know why this may be happening or how to fix it? Thank you! Title: Nice done Name: JayBe Date: PM Comment: Thank you very much for this nice walkthrough, finally somebody who's working with the newer stuff, most of the walkthroughs are for older Visual Studio's and don't usually work good.

Thanks again Title: Reply to: How make a windowservice for continue data storing in table Name: Abhishek Singh Author Date: AM Comment: hi vidyashankar, i think your doubt is very simple to clear. Windows services periodication triggers a user defined funtion using Timer object. Like in the above example you can see code: ' Dim tDelegate As Threading. You can set timeinterval for each trigger for the service. Timer takes it in millisecond. Then build the setup project,install the service and start..

Hope it is clear to you. Thanks a lot. If you click on the timer and look at it's properties you will see which one you have. Then again this service needs to be re-installed not just restart then it runs perfectly very well. This service does some Asynchronous task using delegates. I could not understood this behaviour,let me know how can I understand it or what could be reasons.
