RegOpenKeyEx在Windows 7上失败，87

Question

我试图在Visual Basic 2005 Express中打开注册表项：

Private Const HKEY_CURRENT_USER = &H80000001
Private Const KEY_READ = &H20019    
Dim longResult as Long
Dim hKey as Long
longResult = RegOpenKeyEx(HKEY_CURRENT_USER, "Software\AppDataLow", 0&, KEY_READ, hKey)

但是我总是在longResult中得到错误87。 由于这是Windows 7 64位我也试过

KEY_READ Or &H100
KEY_READ Or &H200
KEY_READ Or &H300

但这些都不起作用，总是得到87返回值，意思是＆＃34;无效参数＆＃34;。 RegOpenKeyEx的声明是：

Private Declare Function RegOpenKeyEx Lib "advapi32.dll" _
    Alias "RegOpenKeyExA" ( _
    ByVal hKey As Long, _
    ByVal lpSubKey As String, _
    ByVal ulOptions As Long, _
    ByVal samDesired As Long, _
    ByVal phkResult As Long) As Long

提前致谢
