Hello all,
Can anyone point me to sample code that can be run as
a Windows Service. I would like to run this code in the
background as a service that is automatically re-started when
the server is re-restarted.
I believe that I need to inherit from System.Service.ServiceBase,
but I'm not sure of how to do this in J#.
Any help will be greatly appreciated.
Charles

Hello - Here is a quick sample I posted a while back for this. It's a port
of a C# Windows Service Sample. Note that I changed this to prompt for a
user account. This should work as skeleton code and to help you get
started, but you'll want to have a look at the documentation for this API.
You can also configure your sevice using mmc (Microsoft Management
Console). Set it to "automatic" to have it start when the system boots.

... This is the result of taking
the C# QuickStart sample and re-coding it to VJ# syntax, etc. I've left
some of the original C# commented in the source. See the MSDN docs and the
QuickStart sample for info. on the classes used and you should be okay.
Also, need the installutil.exe tool found in
%SystemRoot%\Microsoft.NET\Framework\vx.x.xxxx
Regards,
-Bob
