I have configured many computers with LAN IP. Please tell me how to write a program that can send information to an IP in easy language. thank you

Ok, I will teach you how to use the command net send.

Format: the network sends IP "message content"

First, make sure that the messenger service in your computer service is turned on. Of course, it is on by default.

For example, if his IP address is192.168.0.12, then you can enter net send192.168.0./2 "God bless China, Japan will die.

Then you can send the message to his computer, and a window will pop up to display the message content. After reading the message, you can click OK to close the window.

Another method is to directly input the "message content" of NetSneddIP at the beginning of running, and the effect is the same.
