Hi.
I have a big software already running in many companies.
As a measure of security, I want to add to it a module that checks in a website (ftp with username & password) if I want the program to block it self, or send messages to user, or update it self, etc.
It download the file perfectly! The problem is it takes a little while to do it (like 3-5 seconds, and if it's offline, like a minute) and during it, the whole software freezes until it ends. I tried moving the routine to another form, but it's the same. I also thought of moving it to an independent exe that triggers when the main one runs, but nowadays Windows is so paranoic it would be very caotic (sandbox, firewall...) it has to do it quietly.
Any suggestions? I'm thinking of doing it when the program closes, or when it's inactive for 1 minute, but still, it's awkward and it just can't freeze like that, my clients are going to report it to me. TO SUM UP, I need it to do it quietly, silently, in background, no freezing (or at least that if it's offline, doesn't freeze for 1 minute).
The code I use is:
and I call it this way:
THANK YOU VERY MUCH.
