但是在用的过程中，就算我添加了#inclue <winbase.h>，编译时也还是提示GetSystemTimes函数未定义。
在本地计算机进行搜索后，发现在C:\Program Files\Microsoft SDKs\Windows\v7.0A\Include中的winbase.h里面有这个函数，但系统每次都找到的都是C:\Program Files\Microsoft Visual Studio\VC98\Include中的winbase.h。
尝试了两种方法改正：
1、将正确的winbase.h文件拷到project目录下，代码中改为#include "winbase.h"，依然找的是C:\Program Files\Microsoft Visual Studio\VC98\Include中的winbase.h，失败；
2、在Tools->Options->Directories中将C:\Program Files\Microsoft SDKs\Windows\v7.0A\Include换到最上方，又出现另一个错误：cannot open include file 'sal.h'，仍然失败。
请问各位大侠，是我引用头文件方法不对吗？还是别的什么原因？希望哪位知道的大侠指条明路给我吧，不胜感激～～～

#include<windows.h>，可以
#2
试过了，也不行
#3
#include <windows.h> 应该是对的！
#4
试试 #include "windows.h"
#5
试过了，也不对
#6
刚刚在写代码的时候这个问题又出现了，极度无语中，知道的同学站出来说下吧，不胜感激～～～
#7
这个winbase.h文件应该怎么include到对的呀，抓狂撞墙中，，，

是不是因为配置选项的include中，C:\Program Files\Microsoft Visual Studio\VC98\Include在C:\Program Files\Microsoft SDKs\Windows\v7.0A\Include的前面导致的？试着将两项换一下位置

可能是VC6生成的程序吧，将_WIN32_WINNT定义 为0x0400 或0x0500
#11
不好意思，请问应该在哪里将_WIN32_WINNT定义 为0x0400 或0x0500？

查MSDN是Windows程序员必须掌握的技能之一。
ms-help://MS.VSCC.v90/MS.MSDNQTR.v90.chs/sysinfo/base/getsystemtimes.htm
GetSystemTimes Function
Retrieves system timing information. On a multiprocessor system, the values returned are the sum of the designated times across all processors.
BOOL WINAPI GetSystemTimes(
__out LPFILETIME lpIdleTime,
__out LPFILETIME lpKernelTime,
__out LPFILETIME lpUserTime
);
Parameters
lpIdleTime
A pointer to a FILETIME structure that receives the amount of time that the system has been idle.
lpKernelTime
A pointer to a FILETIME structure that receives the amount of time that the system has spent executing in Kernel mode (including all threads in all processes, on all processors).
lpUserTime
A pointer to a FILETIME structure that receives the amount of time that the system has spent executing in User mode (including all threads in all processes, on all processors).
Return Value
If the function succeeds, the return value is nonzero.
If the function fails, the return value is zero. To get extended error information, call GetLastError.
Remarks
To compile an application that uses this function, define _WIN32_WINNT as 0x0501 or later. For more information, see Using the Windows Headers.
Requirements
Client
Requires Windows Vista or Windows XP SP1.
Server
Requires Windows Server 2008 or Windows Server 2003.
Header
Declared in Winbase.h; include Windows.h.
Library
Use Kernel32.lib.
DLL
Requires Kernel32.dll.

应该是动态库没有链接 吧
#14
放到当前目录下用""都搞不定是不是应该换个编译器试试，或者重装一下！
#15
一般在 stdafx.h中，如果没有自己定义
你看看winbase.h文件，如果_WIN32_WINNT小于0x0400,GetSystemTimes是没有定义的（#ifdef...）
#16

可以在工程设置里定义
工程属性--〉C/C++ --> Preprocessor --> Preprocessor Definitions里加上_WIN32_WINNT=0x0501
#17
不那是没有头文件吧
#include <atltime.h> 你加进去看下应该是可以的哦！
MSDN上面很明确说明了 要加这个头文件的
