Hello to everyone,
I don't know if this is the correct thread to post my question, I'm sorry if I made a mystake.
However my question is, how can I refresh my web page to all active user without they refresh the page?
Example: there are 2 users connected on my web application, when a new user connect on my apps I want to show to other user that a new user is now connected and I want to show some GUI element, such us an image or a label.
Go to the complete details ...
