Service and Client

Jeff Williams

I need to develop an application that runs as a service. Easy there are
samples on how to do this.

I need to have a client which updates information for the service. Easy
to do.

How do I notify the Service that details have been changed by the Client
and the Service needs to re-read the data and update its self.

I would like this to work on a single PC but must consider that I may
need the client running on several PC's with the service on a server.

I would like to send a message from the client(s) to the service and the
service reload the data at a predefined times.

Regards
Jeff

From the Client, use the ServiceController class which has a method
called ExecuteCommand that lets you send an integer to the server.

On the server, override the method OnCustomCommand, which will fire when
the client sends the ExecuteCommand.

Dear Jeff,

You can use any IPC mechanism such as named pipes, Remote procedure
calls etc.

Since you want to consider IPC over network, I would suggest using Web
Services Enhancments messaging technique (using for instance the the
soap:tcp protocol).

Refer to this article on WSE:
http://msdn2.microsoft.com/en-us/library/ms977323.aspx

Feel free to ask any questions regarding IPC or WSE.

When both client and the service are .NET applications, you should take a
look at Remoting (Framework V2) or WCF (Framework V3). Consider using the
IPC channel for local connections (same box) and the TCP channel for LAN
connections.
