分享怎样用SHChangeNotifyRegister监视驱动器改动,各位大虾请进来看看
如题,
SHChangeNotifyRegister的原形如下:
SHChangeNotifyRegister
(
HWND hwnd, //1
int fSources, //2
LONG fEvents, //3
UINT wMsg, //4
int cEntries, //5
SHChangeNotifyEntry *pfsne //6
)
我还是不太懂第2,5,6个参数该怎样设置
我要监视SHCNE_DRIVEREMOVED和SHCNE_DRIVEADD消息
那么第二个参数应该是什么值呢,不知是否是0x0002(SHCNRF_ShellLevel)
第5,6个参数真不知道干什么用
请各位大虾指点迷津!
万谢!

我的不是vs.net的。是vc6的程序。但是由于SHChangeNotifyRegister等函数在vc6的库里没有，所以我用了2003的库。
第5个参数是需要监视的个数。

开始监视：
ULONG id = 0;
LPITEMIDLIST pidlRoot = NULL;
LPMALLOC pMalloc = NULL;
SHGetMalloc(&pMalloc);
SHGetSpecialFolderLocation(m_hWnd,CSIDL_DESKTOP,&pidlRoot);
SHChangeNotifyEntry SHCNE;
SHCNE.pidl = pidlRoot;
SHCNE.fRecursive = TRUE;
id = SHChangeNotifyRegister(m_hWnd,SHCNF_TYPE | SHCNF_IDLIST/*SHCNRF_ShellLevel*/,
SHCNE_ALLEVENTS | SHCNE_INTERRUPT/*SHCNE_CREATE*/,
WM_CHANGED,1,&SHCNE);
if(pidlRoot)
{
pMalloc->Free(pidlRoot);
}
pMalloc->Release();
结束监视：
SHChangeNotifyDeregister(id);
收到文件变化的消息处理：

谢谢两位,我想知道第五个参数为什么是1,它是干什么的
两位似乎监视的都是CSIDL_DESKTOP
我想应该是CSIDL_DRIVES吧,

您好像用的是VS.net,我其实是在C#里面调用这个API,您能看看我的程序吗?http://community.csdn.net/Expert/topic/4117/4117745.xml?temp=.1138422
