 Did anybody run across the problem that I have. I created a service and installed on the remote pc. The service is supposed to start an exe that is located on the LAN server. The started exe is checking a couple of the LAN drives/paths and that's where it fails. For some reason the service started exe has a problem of seeing LAN drives. The other thing is that the exe has "NETWORK SERVICE" User Name under Windows Task Manager vs. logged in user name. Can anybody help (permission???, user name???)? Any help is appreciated!

Your service doesn't run in the context of the logged in user. You'll have to go into the Services control panel and change the account that it runs under. Create an account that has the appropriate rights to all the resources that the service will need. It's done just like creating an account for a normal user. Change the account details in the Services control panel for your service, then restart it. So long as the account is setup correctly, your application will run using those credentials.

thanks for the response. I’ve changed the settings to look up the created account and it disabled “Allow service to interact with desktop” and I need that because I want to run applications as if I manually started them. The server started the app but I it’s invisible. Any ideas how to go around this problem. Thanks.

Unfortunately, you can have one or the other, not both. You're option is to run the service with the appropriate account to do its job on the network, then have a second application run from the Run registry key when the user logs in and have it provide the user interface and interaction with the service app through .NET Remoting.

I’ve been straggling for more than two weeks to get my server apps running remotely starting by the service and I guess I have to look for different options. Do you by any chance know any sources or books that talk about how to implement my idea? Thank for your time.

So I have been trying with not much luck to get Instances to work with my custom Performance Counters. I've looked everywhere I could think of, and the documentation isn't even close to good on how to create and then use instances with my custom counters. Perhaps I'll have to post an article on what worked for me so I can get feedback on what I should have done  I found a newsgroup posting that claimed you had to reboot to get the instances to appear for a new custom counter. Only recently after rebooting did I get my instances to register when my application begins, I had tried everything short of rebooting to get them to appear in perfmon.
Now the issue with my instances is that the Instance names are all in lower case. I have not set them to be like this, is this a known issue? The Microsoft applications that have Performance Counter Instances don't use all lower case Instance names, so why must I? I want to be cool.
My code to create an instance looks like this:
PeformanceCounter PC1 = new PerformanceCounter("MyCategory", "Some Counter", "Value One", false);
I can then do things like increment and set the raw value, but in perfmon (and through the enumerating instance names with c# code) the instance name is; "value one". The Category and Counter names have the proper casing I used, but the Instance Name does not. This happens with all of the Instance names I try to use with my custom counter. Thanks in advance for any advice.

I am trying to design a new class Library but have questions about separate logic from base class(with base namespace BaseNamespace).
I have the base namespace BaseNamespace and inside it the nested namespace System. And inside System there is a normal class for action - File. I think about the size of this base class and its different namespaces. It cannot be to use #region statement for better handling. I need to write the logic of File (for example) to another class(own class file). There is no problem with it, if I call such methods, attributes a.o from another class, but is there a general design guide for builing huge class libraries ?
namespace BaseNamespace<br />
{<br />
namespace System<br />
{<br />
public class File<br />
{<br />
}<br />
}<br />
}

Hello All,
Doing a really simple import of a csv file using odbc. A sample line of that file may look like this:
200,-,0,-,461020,-,0,.,30,-,0
For some reason, it doesnt seem to want to import the '-' character, it actually returns a 0 on a tostring of that character. I did try converting it tochar. Any suggetions on how I get the actual value?
Thanks,
Ryan

Hi,
I would like to delete some lines from a textfile. Can I delete
or modify lines in a textfile or should I create a new file and copy the new content to it?
Thank's for answers!
Br,

That's exactly what you should do. Read every line from your source file, and if you want it in the destination, write it; Otherwise, skip it.

Hi,
i am trying to use a DLL(LibPl.dll) which was written C++. I imported the native Methods via DLLImport:
<br />
[DllImport(DllFileName)]<br />
internal static extern uint PL_new_term_refs(int n);<br />
When I use this Method (PL_new_term_refs) in the Main Application everything works fine.
But if exactly the same Code is called via an event/delegate it is not working
anymore. What I get is the following Error:
<br />
An unhandled exception of type 'System.NullReferenceException' occurred in aflib.dll<br />
<br />
Additional information: Object reference not set to an instance of an object.<br />
<br />
Unhandled Exception: System.NullReferenceException: Object reference not set to an instance of an object.<br />
at ArteFACT.Rule.libpl.PL_new_term_refs(Int32 n)<br />
It seems that it can't find the static method at all.
Does anybody have an Idea what it could be? Because I could not really
find anything on the web and debugging didn't really help as well.
Thanks in advance,
Chris

I've created a windows service that as the time passes it start to consume a lot of memory. I'm using a managed zlib library for compression (one published here). I tried to force a garbage collection but it doesn't work. Question is: can I send a restart command to the service from within the service ?

No you can't. A service doesn't "restart", but first "stops" then "starts". This will kill your service, but it won't start back up again because your code has been stopped.
A MUCH better method would be to find out why your code is leaking and fix it, instead of taking the "lazy" way out and ignoring it. 99% of the time, you're not releasing unmanaged resources, by calling .Dispose on your objects or because you forgot to call an unmanged function of your component that tells it to released its unmanaged resources. Either that, or you're using a buggy, unmanaged components.
The garbage collector will collect and free managed resources only. It can't do anything about unmanaged resources allocated by unmanaged components, even if those components are wrapped in managed code.

Is there anyway that I can isolate my unmanaged call ? I tryed to use appdomains but it didn't work...

That is still no solution for leaky code. There is just no excuse for leaving a leak in there like that. You have to go over the calls you're making to the unmanaged library and make ABSOLUTELY SURE, without a shadow of a doubt, that you're properly releasing those unmanaged resources. The documentation on the library your using will most likely help with that.
You said your using a library downloaded from CodeProject. Post a message in the aritcle's forum that you downloaded the library from. Maybe there's a known bug and a fix for your problem there. Check with the auther and ask where the underlying unmanaged code came from and if there any doc's on it.

About leaky code...
I suggest you get yourself a profiler. True lifesaver. There are bugs that are nearly impossible to find without one. Try the one from SciTech... memprofiler.com[^]. They also have a great tutorial on the website.
