...online users ...indy udp ...chat ...
Where did you read the information about 'online users', 'chat' and udp?
i didnt read them yet because i did not understand how to be done or get the logic about it , in other programing langauge like php simply we use session of the users to sort it on the database , but in delphi its another story also set ability to each user by there premission on database its another story with delphi i never found an example about it to be able to understand the whole process ,, in my case
i use zeoslib to retrive a spcific user data and i already did the login and it was easy but the hard thing is how to set premession to each user that logged in , how to allow the user to see if some users entered the chat or left it .
