Winsock. h and winsock2.h conflict resolution

Today, we changed the original project from MFC to a non-MFC project, and many errors have occurred. Now we have recorded them as backups.

Solution: compile the project with the compilation header.

Add the following in stdafx. h:

# Ifndef win32_lean_and_mean
# Define win32_lean_and_mean
# Endif

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

Modify in targetver. h

# Ifndef winver // specify the required minimum platform as Windows Vista.
# Define winver 0x0600 // change this value to the appropriate value for other Windows versions.
# Endif

# Ifndef _ win32_winnt // The minimum platform required is Windows Vista.
# DEFINE _ win32_winnt 0x0600 // change the value to the corresponding value for other Windows versions.
# Endif

# Ifndef _ win32_windows // The minimum platform required is Windows 98.
# DEFINE _ win32_windows 0x0410 // change this value to an appropriate value for Windows ME or a later version.
# Endif

# Ifndef _ win32_ie // The minimum platform required is Internet Explorer 7.0.
# DEFINE _ win32_ie 0x0700 // change the value to the corresponding value to apply to other IE versions.
# Endif

Then compile

Stdafx. cpp File

This problem will not occur after compilation of other files.
