# Include and conflict improvement solutions

# Include <windows. h> # include <winsock2.h>

The aboveCodeThis may cause a redefinition error because windows. h contains Winsock. H (not winsock2.h). Baidu's solution is to add

# Define win32_lean_and_mean

Compiled, OK!

However, because the socket Project is a DLL project, when the DLL is referenced to another project (such as duilib), an error occurs. The error is caused by win32_lean_and_mean, therefore, this solution needs to be improved.

After testing, we found that the following code can solve the above problem.

# DEFINE _ winsockapi _ # include <windows. h> # include <winsock2.h>

Done.
