I have an interesting challenge and was hoping one of the gurus can assist.
I have a program running on a client machine that I need to "trigger". The program is written in VB.NET.
What is the easiest way I can generate a "trigger" to that client machine?
Couple of things I already considered:
a) check for a presence of some file (too cumbersome)
b) implement sockets and listen on some port for a trigger (too complex, error prone)
c) check some website for a presense of something and use that as trigger (too much work, must setup site, read it ...)
... is there anything simple that anyone can think of? Ideally if I could "ping to a port" and then have the client just listen to any activity on the port would be ideal, but I don't know if this is possible.
Thanks in advance for any ideas...
