以上数据需要包含文件#include <winsock2.h>
如果包含顺序为：
#include <stdio.h>
#include <windows.h>
#include <commctrl.h>
#include <winsock2.h>
#include "resource.h"
#include "Definition.h"
那么会出现一大堆错误，如下

现在将包含顺序改为：
包含顺序为：
#include <winsock2.h>
#include <stdio.h>
#include <windows.h>
#include <commctrl.h>
#include "resource.h"
#include "Definition.h"
那么将没有任何编译错误。
