How to enable the C# windows service application write access to some folder and eventLogs

I created the simple service and in OnStart method written file write creation operation. It fails however.

Either adding eventLog.WriteEntry component without try/catch blocks in the OnStart method generates exception to Windows Applications Log as System.Security.SecurityException in System.Diagnostics.EventLog.WriteEntry()

What (user)account does your service use?
LocalSystem?

LocalService.

I found out that changing it LocalSystem, NetworkSystem created the file in windows\system32 directory.

Thus, creating file by providing the name, does not create it in the directory of the servise exe.

After I provided full path to the service dir with LocalService the file has been created.

However eventLog still does not work.

1. To have full access to all paths you want, just create a new user, give him all rights he should have and assign him to your service.

2. In my opinion your problem with the EventLog, has an other cause. Because normally LocalSystem has the
rights to access the EventLog and if you look at your installed services on your computer you will find many services working under LocalSystem and can write to EventLog.

So can you please provide your code you use to write to eventlog?

Yes, after I changed to LocalSystem and the event logging worked.

BTW do you know how to interact with the service?

1) When I execute custom command using ServiceController from external app it throw exception that the service can not be manipulated.

2) Is there any way to retrieve the data from the service, e.g. return codes from command execution?

Marshal.FinalReleaseComObject locking up

There are many ways to interact with your service.

1. Build a tiny TCP/IP server in your service and let your clients interact with this service.
To get started with this take a look at the .NET classes TcpListener, TcpClient and Socket.

2. Use interop-functions to interact with your service.
To get started with this, learn how to use one event in more then one application (CreateEvent, SetEvent, ResetEvent, CloseHandle) and how to map a shared memory block (CreateFileMapping, OpenFileMapping, MapViewOfFile, UnmapViewOfFile).

3. Use named pipes.

Anyone else run into this issue? I'm using a third-party system via an RCW-wrapped COM interface in a console app... When I try to clean up during a reconnect (It's a network interface to their servers), I'm running the following simple line on each component, in reverse order of instantiation:

if ([component] != null)
   Marshal.FinalReleaseComObject([component]);

Simple, right? Well, the trouble is that it's locking up solid at this point. It doesn't return or throw an exception. I've tried with the old-style ReleaseComObject (Which only decrements once), but it does the same thing.

I think it has something to do with the context, as this is a console application with 3-4 background threads (Will be turning it into a windows service), and this is running on a thread that was instantiated within the COM library.

Any ideas on how to make this thing return, or at least crash so I can handle and recover?

Proud to have finally moved to the A-Ark. Which one are you in?

The scope of your request is far beyond what can be provided by this forum. It would take many man years of effort to develop such a system.

This way:

Process.Start("winword","a.doc");
Process.Start("winword", "b.doc");

It's not necessary to be so stupid, either, but people manage it. - Christian Graus, 2009 AD

Localizing C# win forms application

26-Oct-09 17:29

Dear frined,

thanks for your replay..

i tried as you have given ... a.doc and b.doc started as two diffrent windows and runs as one process?

i want that to be run as two diffrent process.

and moreover i have given example as (Winword.exe) if it is going to be all the file types then ( it is not possible to specify "winword"(ExE name) as argument) for all the types.

Thank U

With GUI controls to localize the language it needs only to set Form->Localizable to true and selecting any specific language will enable us to edit GUI controls Text properties.

The corresponding satellite assemblies are created automatically and placed into say es-SP or de-AU folders.

How to perform the same with string resources? that these ones will be put inside those already compiled satellites.

MSDN help relates only manual creation of such resources with al.exe tool and generating say MyApp.resources.dll from the scratch.

It will give us 2 MyApp.resources.dll files, one from al.exe and the other from all GUI localized forms.

There should be the same way to allow to add to the project such string resources for every culture we are targeting without al.exe usage?
