Creating Windows Services programatically - help

[Amongin Ewinyu]

Hi,

I'm trying to create a Windows service programmatically that will do the
following:

- When a user logs on, it will automatically run a service that uses BITS
(Background Intelligent Transfer Service) to check for the most current
version of a file and downloads this version.

I have a wrapper class thats imported as a reference in order for me to be
able to use BITS.

I am able to run and install the service into the SCM but when I attempt to
start the service I get the following message:

"The test service on Local Computer started and then stopped. Some services
stop automatically if they have no work to do, for example, the Performance
Logs and Alerts service."

I then see the following message logged in the Application Event viewer:

"
Service cannot be started. System.IO.FileNotFoundException: File or assembly
name Microsoft.Msdn.Samples.BITS, or one of its dependencies, was not found.

File name: "Microsoft.Msdn.Samples.BITS"

at testBits.startBits.OnStart(String[] args)

at System.ServiceProcess.ServiceBase.ServiceQueuedMainCallback(Object state)

=== Pre-bind state information ===

LOG: Attempting download of new URL

"

Could someone please tell me where i'm going wrong and/or what I need to
change.

Thanks.

I have a wrapper class thats imported as a reference in order for me to be
able to use BITS.

Have you tested the wrapper in a regular Windows Forms app to make sure
it works properly?

Service cannot be started. System.IO.FileNotFoundException: File or assembly
name Microsoft.Msdn.Samples.BITS, or one of its dependencies, was not found.

File name: "Microsoft.Msdn.Samples.BITS"

Is the wrapper file installed in the correct location? And are any
files it depends on also installed correctly?

Yes I have tested the wrapper in a regular Windows form app. and it works
perfectly, the problem occurs when I try and use the same code in the
OnStart method of the Service class.

The wrapper depends on on two other files and they are all stored/installed
in the same location, which is the directory of the project.
- Is this the correct location?
- Is there a particular place that I need to install the wrapper file and
its dependencies for it to work?

Also I have noticed that the wrapper class and its dependencies do not have
any public key tokens, could this be causing the error?

Thanks, Amongin
