hwnd 是 winuser.h 的 udefined c++ 导入

Question

#include "stdafx.h"
#include <winuser.h>
#include <iostream>
#define WIN32_LEAN_AND_MEAN

using namespace std;

typedef struct tagRECT
{
    LONG    left;
    LONG    top;
    LONG    right;
    LONG    bottom;
} RECT, *PRECT, NEAR *NPRECT, FAR *LPRECT;

int main()
{
    RECT newrect;
    AdjustWindowRect(&newrect, WS_BORDER, true);
    cout << "Hello, world, from Visual C++!" << endl;

}

This code cann't be compiled, it has more than 500 errors The most occurring is HWND is undefined . I am confused because winuser is standard header. How to fix it please? Main goal is to program code that will be giving me size of window of hwnd, this was some first sample how to get near the goal with AdjustWindowRect function.

永远不要直接包含<winuser.h> ，而是包含<windows.h> ，也许首先定义WIN32_LEAN_AND_MEAN以减少该标题带来的所有内容。
