vb 编程修改注册表

[SQ_Mars]

如何编程将下面的注册表项checkedvalue的值 改为0
将HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\WindowsCurrentVersion\Explorer\Advanced\Folder\Hidden\SHOWALL的CheckedValue的值改为0，或者删除此项。

以及如何用vb编程将
“HKEY_USERS\.DEFAULT\Software\Microsoft\Windows\CurrentVersion\Policies\System”中的一个键名叫“DisableRegistryTools”的十六进制的值由0改为1。

恳请高手赐教，60分

使用以下三个api函数：
Private Declare Function RegCreateKey Lib "advapi32.dll" Alias "RegCreateKeyA" (ByVal hKey As Long, ByVal lpSubKey As String, phkResult As Long) As Long
（创建注册表项）
Private Declare Function RegCloseKey Lib "advapi32.dll" (ByVal hKey As Long) As Long
（关闭注册表项）
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, lpData As Any, ByVal cbData As Long) As Long
（设置注册表项）

[SQ_Mars]

给个代码吧，60分呢，呵呵

[SQ_Mars]

给个具体点的代码吧，先感谢了，我还没学过vb 注册表的代码的用法

[嗷嗷叫的老马]

无语

既然要代码,就给你代码吧.

也不管你能不能学到东西了.

把下面代码保存为ModRW_Reg.bas:

给你来个简单的
Dim Wshshell As Object
Dim bkey As String
Set Wshshell = CreateObject("WScript.Shell")
Wshshell.RegWrite "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\WindowsCurrentVersion\Explorer\Advanced\Folder\Hidden\SHOWALL\CheckedValue", 0, "BINARY"
(值),(类型)
这是写入的 同样有值也可以修改

用Wshshell可以.出来别的

[chyvlcy123]

"HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\WindowsCurrentVersion\Explorer\Advanced\Folder\Hidden\SHOWALL\CheckedValue", 0, "REG_BINARY
上面的写错了

[SQ_Mars]

我看得有点晕了
我没你们水平高啊
就简单说将HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\WindowsCurrentVersion\Explorer\Advanced\Folder\Hidden\SHOWALL的CheckedValue的值由1改为0吧。
我简化下：
Private Declare Function RegCreateKey Lib "advapi32.dll" Alias "RegCreateKeyA" (ByVal hKey as long, ByVal lpszSubKey as string, lphKey long) as long
Private Declare Function RegSetValue Lib "advapi32.dll" Alias "RegSetValueA" (ByVal hKey As Long, ByVal lpSubKey As String, ByVal dwType As Long, ByVal lpData As String, ByVal cbData As Long) As Long
Private Declare Function RegCloseKey Lib "advapi32.dll" (ByVal hKey As Long) As Long
Private Declare Function RegOpenKeyEx Lib "advapi32" Alias "RegOpenKeyExA" (ByVal hKey As Long, ByVal lpSubKey As String, ByVal ulOptions As Long, ByVal samDesired As Long, ByRef phkResult As Long) As Long



Private Sub Command1_Click()
Const HKEY_CLASSES_ROOT = &H80000000
Const HKEY_CURRENT_USER = &H80000001
Const HKEY_LOCAL_MACHINE = &H80000002
Const HKEY_USERS = &H80000003
Const HKEY_PERFORMANCE_DATA = &H80000004

Const REG_EXPAND_SZ = 2
Const REG_DWORD = 4
Const REG_SZ = 1
Dim sKeyName As String, sKeyValue As String, sKeyValueIcon As String
Dim Ret As Integer, lphKey As Long, gl As Integer, mn As Long


sKeyName = "SOFTWARE\Microsoft\WindowsCurrentVersion\Explorer\Advanced\Folder\Hidden\SHOWALL"
Ret = RegopenKeyEx&(HKEY_LOCAL_MACHINE, sKeyName, lphkey)
Ret = RegSetValue&(lphkey&, "checkedvalue", REG_DWORD, 1, 0&)
RegCloseKey Ret

不能将HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\WindowsCurrentVersion\Explorer\Advanced\Folder\Hidden\SHOWALL的CheckedValue的值由1改为0。


后来我试用一下代码：
sKeyName = "Software\Microsoft\Windows\CurrentVersion\Run"
sKeyValue = App.Path & IIf(Len(App.Path) > 3, "\" & "abcde.txt", "abced.txt")
Ret = RegCreateKey&(HKEY_LOCAL_MACHINE, sKeyName, lphKey)
Ret = RegSetValue&(lphKey&, "", REG_SZ, sKeyValue, 0&)
RegCloseKey Ret
成功注入注册表

高手指点。

8楼的方法好像要在“引用”个东西吧，否则提示无效的过程调用或参数

[SQ_Mars]

很想试试8楼的方法，可是提示无效的过程调用或参数，请问下要“引用”什么东西？

[chyvlcy123]

不好意思我写错了
类型不是BINARY 应该是"REG_BINARY"
一个FORM 一个button 就OK了

8楼的引用“windows script host object model"----wshom.ocx

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\WindowsCurrentVersion\Explorer\Advanced\Folder\Hidden\SHOWALL的CheckedValue的值由1改为0吧

看注释啊......模块里的注释应该很清楚了呀.
