Who gave you this project? Obviously you are not qualified to complete it so you should inform them. They need to find somebody else.

don't worry,for a compliacted project i did a great improvement.i tested it today in a network using 3 clients and 1 server.the 2 problems left are:

*When the clients finished their operations,and i restart the computer that i consider as a server the table where i stock data wasn't empty,it remembers the last data entered

*and an other one a little complicated about incrementing a number with a button without restarting the client ,so the moment a client  wanna use a computer he has to see i+1 not i and so one for each client
