看了一个垃圾程序的架构，mmp真坑，自己费了一点功夫才搞定，就直接记录下吧，这个是windows简单的应用程序，但是里面有点复杂，我们需要首先建立一个基于mfc的appwinzard程序，（凭记忆写的，不知道单词有没有错误），然后我们直接在winmain类中添加下面的变量

# include<time.h>

# define WM_CLOCK USER+20
# define WM_CLOCK_INTERVAL 1000

struct tm *newdate;
time_t long_date;
TCHAR szTimerTitle[MAXSTRING];

加下来由于我们调用了time.h文件，但是我们并没有含有这个文件，我们这个时候直接生成time.h的文件，内部代码如下：

//<time.h>
#if     _MSC_VER > 1000
#pragma once
#endif

#ifndef _INC_TIME
#define _INC_TIME

#if     !defined(_WIN32) && !defined(_MAC)
#error ERROR: Only Mac or Win32 targets supported!
#endif


#ifdef  _MSC_VER
/*

 * alignment.
 */
#pragma pack(push,8)
#endif  /* _MSC_VER */
