We have a program running on an old UNIX box, written in Tickle, that FTPs files to a NT directory. Another program (VB) picks up the files, converts their format, moves them to another directory,etc...
Rather than have a service that runs every few minutes, I would like to have the VB program waiting, idly, for a message from the sending program, who will then do the converts, etc..
The data is ultimately stored in a SQL_Database. The originating program could (maybe) write to a field in the SQL database that would trigger the event. The VB program could be coded and set up on NT to wait for a specific instruction from the Tickle program. Of course it will have to cross platforms from old UNIX to NT.
Any help is appreciated.
