求一个操作注册表的可用例子行吗?

操作注册表有些程序需要随系统启动，或者需要建立某些文件关联等问题，这些都是通过在安装程序中对注册表进行操作的结果。Inno Setup中通过[registry]段实现对注册表的操作。本段说明：参数列表：参数说明 Root 根键。必须是下列中的一个: HKCR (HKEY_CLASSES_ROOT) HKCU (HKEY_CURR 阅读详情

想求一个确实可用的操作注册表的例子参考.
我想先能判断注册表中是不是有我要注册的消息,没有就创建注册项;有注册消息就读取/修改它,删除的时候也能删除掉注册消息.这样可以能直接使用的例子有吗?

还请问下,要判断要想创建的名称和键是否存在用哪个呢?谢谢了!

楼上兄弟,请问用wscript.shell来读写注册表,什么32位64位都行得通吗?

你就把注册表当成读写文件一样理解就行了， Call w.RegWrite("HKEY_LOCAL_MACHINE\Software\123\456", "中文") 这个就相当于目录是：HKEY_LOCAL_MACHINE\Software\123\,文件名是456 如果你想建一个目录HKEY_LOCAL_MACHINE\Software\123\,那就用 w.RegWrite("HKEY_LOCAL_MACHINE\Software\123\", "") RegWrite后面的参数，如果是\结尾就代表文件夹一样，否则就代表里面的一个键值

Dim w As Object
Set w = CreateObject("wscript.shell")
Call w.RegWrite("HKEY_LOCAL_MACHINE\Software\123\456", "中文")

大哥,我试了很久没有试出来,比如说我想在"HKEY_LOCAL_MACHINE\Software"下如果没有123这个程序名称就创建它,并在它里面创建出一个为567的键并将键值设为"中文".我用下面的方式总是不对:

    Call CreateKey(HKEY_LOCAL_MACHINE, "Software\123", 1)
    Call SetValue(HKEY_LOCAL_MACHINE, "456", "中文")

它总是直接在HKEY_LOCAL_MACHINE下创建键为"456"键值为"中文",大师能不能具体指点下如何才能正确创建? 读取我用的是:Call GetValue(HKEY_LOCAL_MACHINE, "456")能正确读到. 菜鸟没地方去问了,本来就不懂网上的一些贴出来的代码是没验证过的,缺这少那的要不运行不了要不根本就不能读改写. 求教!

如果项不存在就会出错，用这原理写个函数就行了

Private Sub Form_Load()

    Dim w As Object

    Set w = CreateObject("wscript.shell")

    Call w.regwrite("HKEY_LOCAL_MACHINE\Software\123\456", "中文")



MsgBox 检测注册表项是否存在("HKEY_LOCAL_MACHINE\Software\123\456")

MsgBox 检测注册表项是否存在("HKEY_LOCAL_MACHINE\Software\123\4567")

End Sub

Function 检测注册表项是否存在(Key As String) As Boolean

    On Error GoTo Err1

    Dim w As Object

    Set w = CreateObject("wscript.shell")

    Dim V

    V = w.REGREAD(Key)

    检测注册表项是否存在 = True

Exit Function

Err1:

    检测注册表项是否存在 = False

End Function

这里是对注册表：读取，修改，新建，删除等方面的方法，一句话就完成，方便好用

 


Private Sub Command1_Click()
'ie收藏夹默认路径文件夹：%USERPROFILE%\Favorites
On Error Resume Next
Dim w As Object
Set w = CreateObject("wscript.shell")

Dim 原收藏夹路径 As String, 新收藏夹路径 As String
'读取注册表项
原收藏夹路径 = w.RegRead("HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders\Favorites")
'
'更改注册表项
新收藏夹路径 = "d:\IE收藏夹" & Format(Now, "yyyy-mm-dd hh：nn：ss")
MkDir 新收藏夹路径
Call w.RegWrite("HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders\Favorites", 新收藏夹路径)
MsgBox "原收藏夹路径：" & 原收藏夹路径 & vbCrLf & "新收藏夹路径：" & w.RegRead("HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders\Favorites")

'Call w.RegWrite("HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders\Favorites", "%USERPROFILE%\Favorites")
End Sub
Private Sub Command2_Click()
Dim w As Object
Set w = CreateObject("wscript.shell")
'添加一个新项目
Call w.RegWrite("HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders\试验项", Now)
MsgBox "请打开注册表定位该处,然后按F5，检查下是否多了一个项目"
'删除一个项目
Call w.RegDelete("HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders\试验项")
MsgBox "请打开注册表定位该处,然后按F5，检查下是否这个项目消失了"
End Sub

请教兄弟,搜索看了其它方面介绍,64位什么的和XP系统的注册表都可以同样操作吗?还是相互之间的读写方法不同?

Win7 64位或者XP32位都行
