1. New MFC project, the wizard contains Windows sockets support
2. Add a button, the button open a thread,
3. The code is put inside the thread, printf to afxmessagebox show,

CodePudding user response:

This is the most basic knowledge of MFC, suggested the building or the operational process of MFC clear, otherwise this help you to harm you

On the network have a ready-made examples, oneself read code

I put the code in the execution of the BUTTON that made many mistakes in the part of the code, conflict each other, what all not line, get dizzy, I MFC small white,,,,
