vb.net删除注册表,vb注册表清理
删除注册表项里的所有键值（除了指定一个）外，怎么写？易语言编程
建议你使用VB.NET（VS2005+版本），操作注册表非常容易： For Each name As String In My.Computer.Registry.LocalMachine.OpenSubKey("software\microsoft\windows\currentversion\run").GetValueNames

If (name "1425") Then
My.Computer.Registry.LocalMachine.OpenSubKey("software\microsoft\windows\currentversion\run").DeleteValue(name)
End If

VB.net注册表操作问题
最简单的办法就是用shell
语句
添加和创建注册表项
shell
"cmd
/c
reg
add
hklm\software\myco
/v
data
/t
reg_binary
/d
fe340ead"
删除注册表项
shell
"cmd
/c
reg
delete
hklm\software\myco\myapp\timeout"
删除注册表项
timeout
及其所有子项和值
具体语法请在cmd中输入
reg/?
VB.NET如何删除注册表
请使用VB.NET的“My”功能： '添加
My.Computer.Registry.LocalMachine.OpenSubKey("SOFTWARE\Microsoft\Windows\CurrentVersion\Run", True).SetValue("running", "C:\myapp.exe") ' 删除
My.Computer.Registry.LocalMachine.OpenSubKey("SOFTWARE\Microsoft\Windows\CurrentVersion\Run", True).DeleteValue("running")
vb.net 注册表删除操作 郁闷中……
这不是废话吗，DeleteSubKey只能删除调用实例的子项，并不能直接删除子子项。
vb 对注册表的操作,详细解说
赫赫，拿来主义
将下面代码保存为CLS文件 ，然后在工程中引用就可以了。
