[Fallen]

1)Grats for managing to hack sumthing ^_^

2)Its visual only if you dont know how to do it right

3) heres a pic



4) " [DataBase] " is the DB, " <- Server -> " is the server , and " |Client|" the clients.

Lets say you want to buy a book with egold. Heres what happens

When you open the "Mall" window.

|Client| sends a signal to the <- Server -> the server retrieves data from the [DataBase] ex. the name of the book / how much it costs and sends the data back to the |Client|.

After you click "Buy".

|Client| sends a signal to the <- Server -> the server retrieves data from the [DataBase] ex. 1) the amount of the gold you have and 2) how much it costs, finally it sends them back you your |Client| wich calculates the diffrence, sums your gold and sends the new amount of gold you have via the server to the [DataBase].

so, after you click buy you have |Client|->|Server|->|DataBase|->|Server|->|Client|->|Server|->|DataBase|

lets see what happens if you remove the 4th step  and change it to |Client|

|Client| sends a signal to the <- Server -> the server retrieves data from the [DataBase] ex. 1) the amount of the gold you have and 2) how much it costs, [removed]finally it sends them back you your[/removed] |Client| wich calculates the diffrence, sums your gold and sends the new amount of gold you have via the server to the [DataBase].

|Client| sends a signal to the <- Server -> the server retrieves data from the [DataBase] ex. 1) the amount of the gold you have and 2) how much it costs, |Client| wich calculates the diffrence (100-0 = 100 = Positive = True), sums your gold (100-0 = 100 ) and sends the new amount of gold ( = 100) you have via the server to the [DataBase].

Therefore, you end up with a book and still 100 gold
