刪除注冊表項里的所有鍵值（除了指定一個）外，怎么寫？易語言編程

建議你使用VB.NET（VS2005+版本），操作注冊表非常容易： For Each name As String In My.Computer.Registry.LocalMachine.OpenSubKey("software\microsoft\windows\currentversion\run").GetValueNames

VB.net注冊表操作問題

最簡單的辦法就是用shell

語句

添加和創(chuàng)建注冊表項

shell

"cmd

/c

reg

add

hklm\software\myco

/v

data

/t

reg_binary

/d

fe340ead"

刪除注冊表項

shell

"cmd

/c

reg

delete

hklm\software\myco\myapp\timeout"

刪除注冊表項

timeout

及其所有子項和值

具體語法請在cmd中輸入

reg/?

VB.NET如何刪除注冊表

請使用VB.NET的“My”功能： '添加

My.Computer.Registry.LocalMachine.OpenSubKey("SOFTWARE\Microsoft\Windows\CurrentVersion\Run", True).SetValue("running", "C:\myapp.exe") ' 刪除

My.Computer.Registry.LocalMachine.OpenSubKey("SOFTWARE\Microsoft\Windows\CurrentVersion\Run", True).DeleteValue("running")

vb.net 注冊表刪除操作 郁悶中……

這不是廢話嗎，DeleteSubKey只能刪除調(diào)用實例的子項，并不能直接刪除子子項。

vb 對注冊表的操作,詳細解說

將下面代碼保存為CLS文件 ，然后在工程中引用就可以了。
