You should not attach to a process unless you know what the process is and understand the consequences of attaching to and possibly killing that process. For example, if you attach to the WinLogon process and then stop debugging, the system will halt because it can't operate without WinLogon.
You can attach the debugger only to a running service. The attachment process interrupts the current functioning of your service; it doesn't actually stop or pause the service's processing. That is, if your service is running when you begin debugging, it is still technically in the Started state as you debug it, but its processing has been suspended. After attaching to the process, you can set breakpoints and use these to debug your code.
Once you exit the dialog box you use to attach to the process, you are effectively in debug mode. You can use the Services Control Manager to start, stop, pause and continue your service, thus hitting the breakpoints you've set.
You can later remove this dummy service after debugging is successful. This article covers debugging a service that's running on the local computer, but you can also debug Windows Services that are running on a remote computer.
See Remote Debugging. Debugging the OnStart method can be difficult because the Services Control Manager imposes a second limit on all attempts to start a service. For more information, see Troubleshooting: Debugging Windows Services.
To get meaningful information for debugging, the Visual Studio debugger needs to find symbol files for the binaries that are being debugged. If you are debugging a service that you built in Visual Studio, the symbol files. If you are debugging a service that you didn't build, you should first find symbols for the service and make sure they can be found by the debugger. See Specify Symbol. If you're debugging a system process or want to have symbols for system calls in your services, you should add the Microsoft Symbol Servers.
See Debugging Symbols. Install your service. For more information, see How to: Install and Uninstall Services.
The breakpoint is in DLL project. Sergey Alexandrovich Kryukov 7-Mar am. Well, yes, I see what you mean. Maybe be OP first need to embrace the idea of unit testing. And I have my own approach to debugging services not covered here: a dual-mode application which runs both interactively and as service, without modifications.
Very effective. The best way to debug a DLL is not using service. DLL is used as a library. You should better write some debug project for testing the DLL. This is much, much simpler than debugging the service application if you mean a Windows Service. Debugging of Service Application is a special issue, there are different approaches which may require whole article to describe. If the execution is not stopping at a break point, check up all settings and make sure that debug information is enabled, re-build the project.
The other reason could be this: the break point is never reached in your debug session. To isolated different problems, add a break point to the line of code which will be reached for sure, not matter what happens. Then try to figure out where your execution goes and where it doesn't. This and many, many other techniques contribute to debugging skills, very important in development. Posted 6-Mar pm Sergey Alexandrovich Kryukov.
Why not? I don't think you can see a point. The question was not about debugging the service, it was about testing the DLL. Service using DLL is not helping debugginh DLL, only makes is difficult, hence — debugging using some testing project is better. When DLL is fully debugged, no need to debug it more. If you need to debug the service application itself, it will be a different story.
In practice, the words "debug a DLL using a service" is just nonsense. Thank you FOR your help. Abhinav S 6-Mar pm. My 4 this time. Some links to help the OP understand would be useful. Could we nomidis Dec Hello sir, I made the above and happily debugged my project, but only the Process function implementation, its OK, 5 stars! In my service, though, I have a timer event triggering a handler OnStart. Is there a way to debug this as well? Nice Trick granadaCoder Oct By the way Re: Copied article Tejas Vaishnav Nov No not copied from that, i have write this tip in my initial level, as i just joined as fresher to one of the company and i got chance to work on Windows service, at that time i have faced this issue and for solution, one of my senior tech me few ways to debug windows service, so i thought i would be great to share and i share it.
At that time i haven't search like that, if this type of article is already there or not. And thanks for your guiding me towards an old article. Jayesh Goyani. Re: good article Tejas Vaishnav Oct Of course you can set it to run under a custom account even domain account.
However, this article shows debugging or testing under the developer's account, which has completely different permissions. Thus, it won't help the development much as it cannot simulate service account. Another approach is to insert Debugger. Break so as to trigger a Visual Studio attaching event.
If you have know the alternate and easy way then you can write your an article also, what i demonstrate is easy way to debug the windows service, if you not like than you don't follow.
My vote of 1 Lex Li 5-Sep No warning on what can be the problems. This post has been cheated from Lee Humphries's Post. Re: cheated Tejas Vaishnav Aug No my friend i have not cheated about the tip, if any body previously posted than what i can do, At the time of posting this, i have never searched or check that this thing is already posted or not. I have posted this tip when i am just fresher, and i have just learns it from one of my college or superior, so i have thought it will helped others for solving their problem.
My vote of 5 Member 9-Aug My issue got resolved. Re: My vote of 5 Tejas Vaishnav Aug My tip is helping you is good. Try to share this thing with others so they can also resolved their issue if they got stuck at any point.
Have a doubt in myServ. Process nirmalasudar Jun
