OK. Mercy Pierre for the reply(It's my french correct???? :)
The OS will be Linux AS 3.0 and it will be good to know for Windows 2000 and newer also
I don't understand about the processes (I mean I do but I don't know how to code it)
This is the application:
An IP Camera will send images to the server via ftp to a folder. Each user has a folder and I want to know how I can make my app to check the folders ('cause there is going to be many cameras sending files and that means that the app will have to check every folder) every x seconds?
Will I have to make one process for every user or one for each user??????
How do I achieve this??????
Thanks
Alberto
