ReadDirectoryChangesW这个函数是不是不可以

#include "ShlObj.h"
SHChangeNotifyRegister
具体用法自行baidu

下面是我写过的代码的部分，能看明白吗??
初始化
m_objEntry.pidl = 0;
m_objEntry.fRecursive = TRUE;
m_MonitorID = SHChangeNotifyRegister(this->GetSafeHwnd(), SHCNRF_InterruptLevel|SHCNRF_ShellLevel, SHCNE_ALLEVENTS, WM_FILEMODIFY_NOTIFY, 1, &m_objEntry);
消息函数里，处理WM_FILEMODIFY_NOTIFY消息，（我自己定义的）
TCHAR szFileName0[MAX_PATH], szFileName1[MAX_PATH];
PIDLIST_ABSOLUTE *pID2;
pID2 = (PIDLIST_ABSOLUTE*)wParam;
szFileName0[0] = 0; //source
szFileName1[0] = 0; //det
SHGetPathFromIDList(pID2[0], szFileName0);
SHGetPathFromIDList(pID2[1], szFileName1);
if((SHCNE_UPDATEITEM == lParam) \
|| (SHCNE_DELETE == lParam) \
|| (SHCNE_RENAMEITEM == lParam) \
|| (SHCNE_CREATE == lParam))｛。。。｝
结束
SHChangeNotifyDeregister(m_MonitorID);

大神。我用这个函数SHChangeNotifyRegister，把他需要的头文件和库都加载了 为什么还报错SHCNRF_RecursiveInterrupt ，SHCNRF_ShellLevel没有定义呀 @code_abc

我写的测试程序，不能保证你的要求，但是对系统中文件操作的动作进行监视，里面有vs2010的shell32.lib，其他读里面的readme.txt文件
你可以看看

主要功能的代码，就这几行
#include "stdafx.h"
#include "windows.h"
#include "ShlObj.h"
#define WM_FILEMODIFY_NOTIFY (WM_USER + 1)
static TCHAR gs_tarrWindowClass[] = {_T("my_sh_test_win")};

{

SHChangeNotifyEntry objEntry;
ULONG ulMonitorID;

hMain = InitInstance (0, SW_NORMAL);
if(!hMain){ goto WINDOW_EXIT;}
objEntry.pidl = 0;
objEntry.fRecursive = TRUE;
ulMonitorID = SHChangeNotifyRegister(hMain, SHCNRF_InterruptLevel|SHCNRF_ShellLevel, SHCNE_ALLEVENTS, WM_FILEMODIFY_NOTIFY, 1, &objEntry);
while(GetMessage(&msg, NULL, 0, 0))
{

}
