- Sample: Simple Service
-
- Summary:
-
- The Simple Service sample demonstrates how to create and
- install a service.
-
- In this particular case, the service merely opens a named
- pipe of the name \\.\pipe\simple, and waits for traffic.
- If it receives anything, it surrounds the input with:
-
- Foo! [<input goes here>]
-
- and sends it back down the pipe to the client.
-
- The service can be Started, Stopped, Paused, and Continued.
-
- To install the service, first compile everything, and then
- user INSTSRV to install SimpleService as follows:
-
- instsrv SimpleService <location of simple.exe>
-
- Now all you have to do is start it, either using the
- "net start" method or via the control panel Services applet.
-
- Once the service has been started, you can use the CLIENT
- program to verify that it really is working, using the syntax:
-
- client \\.\pipe\simple foo
-
- which should return the response:
-
- Foo! [foo]
-
- If, after playing with the sample you wish to remove the service,
- simple say:
-
- instsrv SimpleService remove
-
- Note that INSTSRV can be a little dangerous -- it'll install
- and remove any service you tell it to, so be careful.
