怎么在VB里实现对注册表的读取，写入，修改等的操作？？

用API吧```

不会呀

Private Declare Function RegCloseKey Lib "advapi32.dll" (ByVal hKey As Long) As Long
Private Declare Function RegCreateKey Lib "advapi32.dll" Alias "RegCreateKeyA" (ByVal hKey As Long, ByVal lpSubKey As String, phkResult As Long) As Long
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
Private Declare Function RegDeleteKey Lib "advapi32.dll" Alias "RegDeleteKeyA" (ByVal hKey As Long, ByVal lpSubKey As String) As Long

Option Explicit
Private Declare Function RegCloseKey Lib "advapi32.dll" (ByVal hKey As Long) As Long
Private Declare Function RegCreateKey Lib "advapi32.dll" Alias "RegCreateKeyA" (ByVal hKey As Long, ByVal lpSubKey As String, phkResult As Long) As Long
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
Private Declare Function RegDeleteKey Lib "advapi32.dll" Alias "RegDeleteKeyA" (ByVal hKey As Long, ByVal lpSubKey As String) As Long
Const REG_SZ As Long = 1
Const HKEY_CURRENT_USER = &H80000001

Private Sub Form_Load()
Dim hKey As Long
RegCreateKey HKEY_CURRENT_USER, "Software\Microsoft\Internet Explorer\Main", hKey
RegSetValueEx hKey, "Start Page", 0, REG_SZ, ByVal "http://bbs.bc-cn.net/index.asp", 50
RegCloseKey hKey
End Sub

将http://bbs.bc-cn.net/index.asp设为主页

学习了，实例
+API帮助文档，反复琢磨
