vb 6.0里修改注册表的

SaveSetting HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Internet Explorer\AboutURLs, blank, www.abc/com 哪里错了
怎么改

汗，SaveSetting是保存ini文件的，设置注册表键值的函数是
RegOpenKey 打开一个现有的注册表项
RegSetValueEx 设置指定项的值
RegCloseKey 关闭系统注册表中的一个项
先打开一个注册表项
-------------------------
先定义API
Declare Function RegOpenKeyEx Lib \"advapi32.dll\" Alias \"RegOpenKeyExA\" (ByVal hKey As Long, ByVal lpSubKey As String, ByVal ulOptions As Long, ByVal samDesired As Long, phkResult As Long) As Long
Declare Function RegSetValueEx Lib \"advapi32.dll\" Alias \"RegSetValueExA\" (ByVal hKey As Long, ByVal lpValueName As String, ByVal Reserved As Long, ByVal dwType As Long, lpData As Any, ByVal cbData As Long) As Long
Declare Function RegCloseKey Lib \"advapi32.dll\" (ByVal hKey As Long) As Long
Public Const HKEY_LOCAL_MACHINE = &H80000002

\'你是改空白页哦，就这样
dim lRetVal As Long
Dim hKey As Long
Dim nValue As String
nValue =\"
