Good stuff, did you come across any issues with simpleIPC, Ive been
meaning to have a go with it for a while...
I had two issues with simpleipc:
- in unix the TSimpleIPCServer.OnMessage event is not fired. To
override this, a solution is to call ReadMessage in the OnIdle event of
the application.
- The other is that there's currently no easy way to diferentiate
between different message types. Let's say i need to send messages
telling i started the job, send the results of the job and than finished
the job. Currently there are two options: send a header in the stream
with a numeric variable and check it when arrive (you lose the comodity
of SendStringMessage) or you send a string with a string marker. I will
propose a change in it (and provide the patch) where we could use the
MessageType (user defined) to identify the message and we could still
use SendStringMessage .
- another potential problem (not tested) is that in unix a file is used
to pass the messages. So if the program crashes the file may not be
deleted and would give that the server is running.
