I created an C# Windows Form Application (Recorder) that records into an mp3 file.  All the dlls and “Lame.exe” are in the folder with the Recorder exe.  I run Recorder successfully from both the command line and a shortcut.

I also created a C# Windows Service (Monitor) that monitors Recorder to make sure that it is running all the time.  If Recorder is not running, Monitor restarts it.  Monitor successfully starts Recorder and everything is working except for the reference to “Lame.exe”.  I don’t get any sound when Recorder is started from Monitor.

Do you know how it might be different to run Recorder from a shortcut and a Windows Service calling it? 

Or is there another way to reference “Lame.exe” for a Windows Service?

Any help would be much appreciated.

Thanks,

(Question) How are you starting "Recorder" from the windows service?

(Answer)

public string AppPath = "C:\\APPS\\DARAudit\\DARAuditV5.exe";
public string AppDirectory = "C:\\APPS\\DARAudit";
//Create process
APPProc = new Process();
APPProc.StartInfo.FileName = AppPath;
APPProc.StartInfo.WorkingDirectory = AppDirectory;
APPProc.EnableRaisingEvents = true;
APPProc.Exited += new EventHandler(APPProc_Exited);
APPProc.ErrorDataReceived += new DataReceivedEventHandler(APPProc_ErrorDataReceived);
APPProc.Start();

(Question)
What path are you referencing?

(Answer)
"C:\\APPS\\DARAudit\\DARAuditV5.exe"

The only real difference is, that "Monitor" could be running under a different user security context, such as LocalService or similar. If that account doesn't have permissions on the "Monitor" folder, it will not be able to reference lame.exe correctly.

(Answer)

I don't think that permissions is the problem.  The "Monitor" Service is running on a standalone computer that is not part of any domain.  I also am using the ServiceInstaller in Visual Studio to install the service.  The account property of the ServiceInstaller is set to LocalSystem.  Please explain this further if you think that is still the problem.

I have all the necessary dll's and "Lame.exe" in the C:\APPS\DARAudit directory where the Recorder exe also resides.  The Recorder App runs fine (Form is OK, other dll is working) except that it is still not referencing the "Lame.exe".  Therefore no encoding is working.  Any other ideas on how to reference the "Lame.exe"?

Please help.

Mitchel,

How do I make sure that LocalSystem has access to this folder? 

The available options for the ServiceAccount are:

1)  LocalSystem - An account, used by the service control manager, that has extensive privileges on the local computer and acts as the computer on the network.

2)  LocalService - An account that acts as a non-privileged user on the local computer, and presents anonymous credentials to any remote server.

3)  NetworkService - An account that provides extensive local privileges, and presents the computer's credentials to any remote server.

4)  User - An account defined by a specific user on the network. Specifying User for the Service ProcessInstaller Account [script removed] member causes the system to prompt for a valid user name and password when the service is installed, unless you set values for both the UserName and Password properties of your ServiceProcessInstaller instance.

The Local System option seems to be the option with the most access.   Is there another place or setting to change?

Thanks,

I have c# windows service, which I am developing in visual studio 2008.

I have noticed that, when I start the service, the current culture info does not match the regional settings on my coputer.

When I am starting c# windows application, it uses the culture info according to my regional settings.

Why is it so ? why the windows service uses "en-US" , instead of using the correct cultureinfo according to my regional settings ?

thanks
