      ++i;
}
::RegCloseKey(hKEY);

DWORD dwIndex=0,NameSize,NameCnt,NameMaxLen,Type;
    DWORD KeySize,KeyCnt,KeyMaxLen,DateSize,MaxDateLen;
RegQueryInfoKey(hKEY,NULL,NULL,NULL,&KeyCnt,&KeyMaxLen,NULL,&NameCnt,&NameMaxLen,&MaxDateLen,NULL,NULL);
KeySize=KeyMaxLen+1;
TCHAR szKeyName[MAX_PATH] = _T("");
    for(dwIndex=0;dwIndex<KeyCnt;dwIndex++)
    {
RegEnumKeyEx(hKEY,0,szKeyName,&KeySize,NULL,NULL,NULL,NULL);

}我是这样用的，这时候查键值的话要重新用RegOpenKeyEx打开吗？
不需要，直接根据hKEY和子键的名称来操作读值的话直接用RegQueryValueEX来读取即可
不好意思，上面回答的有误由于你的leakfix是个文件夹，所以还需要RegOpenKeyEx打开才能读值的
