Stick the user control in a WPF Window; then you can "show" it. Hide the window's "chrome" if that's a problem. Same result.

I am running a Windows Service that executes successfully every 10 minutes. It instantiates an in house dll file and calls a method to do some process. This dll file logs everything throughout the process. Now the problem is I have no clue where this log file is anymore!!
Normally when we use this dll file and call its methods, it will create a folder called "Custom" inside the application path with log files.
I do not see any Custom folder anymore even tho my code runs and I see the results.
How do I find where my dll related log files are?

Hi,
I don't think the DLL file is relevant, services use their own default directory and any DLL they reference would use the same. I guess this[^] will offer more than you are asking for...

Hi,
Thanks for your reply. The registry key only holds the path for the service executable file. And I already know where my service has been installed. I can also see the dell files in there. But I do not see the custom folder and log files that the dll file is generating. They are not in that path.

Hi,
to make sure what file operations are executed, use Process Monitor[^] as Dave already suggested.
My best guess is this: as a service, your code is using C:\Windows\system32 as its default directory; and it won't have sufficient privileges to create a folder or file there, so nothing gets created, and the exceptions got caught and swallowed (which is always a bad idea). If correct, I suggest you set another default path before calling your DLL, using a location that is not full of system files.

You can use ProcMon[^] to watch the file operations of your service.

It is difficult to say anything without seeing your code. It depends on how your code resolves the path.
Program Files folder is generally not accessible to programs and services, you'd have to write log files to User Profile Directory which is usually C:\Users\<username>\AppData.

Search for the file name / mod dates on the drive and / or in program data or user data.
Have a coffee and let it search.
(Check the Windows / custom app "event" logs).

Hi Experts
Situation:
As soon I instantiate a class which implements IDisposable as a member in one of my own classes I make my class also IDisposable; this e.g. in case I instanciate AutoResetEvent or any other synchronization stuff.
My colleagues argue I'm too nitpicking.
So my simple question: Am I to nitpicking in this case?
Btw: I break my rule in case I instantiate e.g. Font 
Thank you very much in advance for your comments.

If your class owns a disposable resource, then it should implement IDisposable. That's not nit-picking; that's just good hygiene.

Sorry to disturb again...
In connection with IDisposable: Should I ever take an attempt to have something like try catch/ finally in protected virtual void Dispose(bool disposing) or is it better to take it as the final destaster if an exception happens in Dispose of "my" owned properties?
My opinion: If something strange happens at this low level I do not need to try (I'm anyway not able to) to solve it.
Thank you very much in advance.

I generally avoid it. The Dispose method isn't supposed to throw manageable exceptions, so if you're just calling Dispose on other managed objects, you shouldn't need to worry about it.

I would at least log it, and figure out why.
The implication is, if it was a "file resource", the file was not closed properly, and so forth.
Ignoring "end of job" problems is not a "thoughtful" solution.

Yep, not a bad idea. Nevertheless it is very low level and I think at this level it is ok also to fail without a log.

On the other hand, a memory leak can bite you days+ later.
That's the poster child for IDisposable.

I'm lazy, so... Please, read this very interesting CP article: Implementing IDisposable and the Dispose Pattern Properly
There you'll find final conclusion:
Quote: As you can see, there are a lot of details involved in properly implementing IDisposable and the Dispose Pattern. However, by following the proper template and rules, you can ensure that your disposable objects are handled correctly and behave as first-class citizens in the garbage collection process.
But Eric Lippert in this article: When everything you know is wrong, part one | Fabulous adventures in coding has got another one:
Quote: I’ve written a lot about the perils of C# finalizers / destructors (either name is fine) over the years...
... here are a bunch of things that many people believe about finalizers, all of which are wrong.
...
All of the myths so far imply that if you have code that absolutely, positively must run because it has some important real-world impact then a finalizer is not your best choice. Finalizers are not guaranteed to run.

My opinion is that you write the code that needs to be written. If your object includes another object that is disposable, it only makes sense to inherit from and implement IDisposable for your code object.
It's kind similar to the C++ new/delete idea.

Hello,
I have multiple clients, each one of them running windows service, How can I connect to that windows service and pass data to it ?
I'm using signalR so I will pass the data from it's HUB
Thanks in advance

The service needs to provide a useable interface that allows you to communicate with it. Most listen on a specific port for specifically formatted commands to be sent to it over TCP/IP. You can host something like WCF inside your service to make things simpler.

Since you are using SignalR, you do not require to connect to the Windows Service at all, just connect to the SignalR and let it do the work for you. Chances are you are using ASP.NET based SignalR (not the latest Core technologies), then you would have a good integration with Windows Service as well as the underlying system.
Just make sure each of those machines are connected to the SignalR, so that there can a communication relay.
