The following is the tool program for LAN chat that I wrote. Although it doesn't have much value, it uses most batch commands, including some important commands and more difficult ones. I'm posting it, hoping that new friends learning batch processing will like it. I believe it's very valuable for everyone to learn and understand relevant batch commands. This is the modified version

It's really powerful, but is it a bit too cumbersome?

Hehe, Windows provides us with NetMeeting. Why not use it?

Thanks, the learning sample provided by the landlord!! Beginners need such things very much!!

Such a good post actually sank.

Good stuff, I'll support it, can learn from it

Take it back and study it, thank you the thread starter!!!

Support............Support

Already bookmarked. Thanks. Learned a lot

Worth researching! Sample Text

Support, the LZ has worked hard

Learning...ing
Can you remove your advertisement?

Got it~ Going back to study, thanks

It has been made very clear above. The purpose of writing this is to learn and practice related batch processing commands, and it is hoped to provide a good case material for beginners. As for other software that can be used, it is not within the consideration range of writing this code.

It's very useful and would be great to add it to the LAN Gomoku in batch processing.

Gomoku needs shared folders, needs to generate files, and can't chat.
