I am having a serious problem connecting to out-of-process COM objects in my windows service application. Whenever I try to create an instance of the COM object, a second instance of the COM server is started up instead of attaching to the already running one. I have tried the following fixes with no results:
1. added these lines to my service:
System.Threadin g.Thread.Curren tThread.Apartme ntState = ApartmentState. STA;
int ret = CoInitializeSec urity(IntPtr.Ze ro, -1, IntPtr.Zero, IntPtr.Zero, 4, 3, IntPtr.Zero, 0, IntPtr.Zero);
2. ran dcomcnfg.exe and changed Default Authentication Level to Default and Default Impersonation Level to Impersonate.
3. Changed the "Log On" settings for the service to use my account/password.
None of these change the situation - however, I still feel it may be a security issue. If I run my app NOT as a service, it works fine.
What's going on here???

Hi,
This problem has been frustrating me for days and I hope you experts can
help me out. I am trying to run a command, which I would normally run from
the command line, from within my C# application. The command runs
successfully from a Windows Form but fails if the application is recasted as
a Windows service. The application is essentially a File Watcher that should
run the process when a file is dropped into a specific directory.

Hi ,
Doubt may be bit trivial , but i wanted to know , what are the exact
benefits derived while we run a background process as an NT service in
windows , we can as well achieve the functionality using standalone exe
, which will keep on running in a loop and do the job till been messaged
to stop .
Essentially , i want the key advantages of implementing process daemons
as an NT Service in windows .

I have written a C# application which should run as a Windows
Service. I must avoid having multiple instances of the application
on one machine so I inserted the following code at the beginning
of the Main() function:
// if this is not the first instance of this application, exit
// immediately. Allow only one instance in the system

Hello,
I have a windows service that I have created in VB 2005. I have it
installed, and running, but it's not functioning correctly. When I try to
"Attach to process", my service is greyed out in the list and I cannot
attach to it. Any idea why? Any help would be greatly appreicated.
Thank you,

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
