如何修改REG_DWORD的注册表键值。。。我的方法老是不对

[cow_boy]

Private Declare Function RegSetValueEx Lib "advapi32.dll" Alias "RegSetValueExA" _
( _
ByVal hKey As Long, _
ByVal lpValueName As String, _
ByVal Reserved As Long, _
ByVal dwType As Long, _
ByVal lpData As Any, _
ByVal cbData As Long _
) As Long '创建或改变一个键值,lpData应由缺省的ByRef型改为ByVal型
Const REG_DWORD = 4& 'DWORD 值

Call RegOpenKey(HKEY_CURRENT_USER, "Software\Policies\Microsoft\Internet Explorer\Control Panel", nKeyHandle)
Call RegSetValueEx(nKeyHandle, "HomePage", 0, REG_DWORD, "Ox00000001(1)", 255) '1禁用,0启用

这我已经试过了。出错
说类型不对，
错误是那个1

改用DELPHI吧！

Call RegOpenKey(HKEY_CURRENT_USER, "Software\Policies\Microsoft\Internet Explorer\Control Panel", nKeyHandle)
Call RegSetValueEx(nKeyHandle, "HomePage", 0, REG_DWORD, "1", 4) '1禁用,0启用
我这样改后，HomePage的值为31,我如何才能改为1.

[uguess]

Call RegSetValueEx(nKeyHandle, "HomePage", 0, REG_DWORD, 1, 255) '1禁用,0启用
