Good job. I'm thinking use some like that to split a big desktop application code into few other applications, maintaining a communication among them. Is it a good case to use mosquitto? If so, I can help you on Windows, testing and etc. best regards, Marcos Douglas _______________________________________________ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/cgi-bin/mailman/listinfo/fpc-pascal
