Re: How to pass parameter from a front-end GUI to a windows service?

Hi,

Basicly what you need is IPC (Interprocess communication) ..
....to accomplish that you could use NamedPipes .. or Remoting .. or TCP/IP
protocol ...

I wroted library on that topic (IPC for .NET):
http://www.habjansoftware.com/ipc_library.aspx
.... it contains IPCServer and IPCClient (and also PipeSender and
PipeReceiver) .. all based on NamedPipes ...
