nd file transfer and other functions into one, with high data transmission efficiency and system security remote control system is being promoted. Development and implementation of the actual needs of the remote control Develop their own remote control, involving the host puter and controlled machines, so the use of Client / Server structure. Delphi programming environment can be used separately on two different puters to be controlled preparation of control and procedures, one for Clientdpr. exe, installed in the controlled machine。 one for Serverdpr. exe, installed in the main puter on. Serverdpr. exe designated to monitor the controlled machine IP address and send instructions to the client Clientdpr. exe, client Clientdpr. exe get mand, and then execute the corresponding instructions in the machine, the results are returned to the host puter. Master side function is implemented as follows: Read mand string into a string array of mands to clear the memory of a stream to a specified target puter (by reading the entered IP address) to send the script to a target puter. When the mand sent to the host puter controlled machine, the machine will be controlled on the unit39。s application program interface calls Windows API functions to perform the received mand. When the controlled unit receives the data, they begin to send the host puter operation. To do this: Read identification control code _ + implementation of the corresponding control code for a procedure or function to achieve the appropriate API function.3 Conclusion Although the remote control can easily manipulate the remote puter, to bring a lot of convenience, but it also the resulting security risks. As the market matures remote control, network security bees more important, only solve this critical issue, to really go for remote control applications.4
