Keep it simple ..... ..... will pass data from A to B - I will probably use a file to put the data in because its quite structured. B will sleep on a timer loop until this something is triggered.
Why not use the exis the very existance of the data transfer file as the trigger. Program A creates the file(s) with the data and then goes on with whatever else it needs to do. Perhaps even creating another data file or appending to an existing one. Program B sleeps on a timer, wakes up, checks for the existance of a/the data file(s). If one/some exist then process, if not then sleep another cycle. I have use this method to pass both fax and email files and other messages to a "server". Naming conventions, folder locations etc can all be used to do any segregation of users/purposes as required. Using this method A and B don't even have to be on the same machine. Hope this helps.
