如何用VB讀取登錄檔的機碼 ?
' 兩種方式
' 1. 使用 API
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 RegDeleteValue Lib "advapi32.dll" Alias "RegDeleteValueA"
(ByVal hKey As Long, _
ByVal lpValueName As String) As Long
Private Declare Function RegOpenKey Lib "advapi32.dll" Alias "RegOpenKeyA" _
(ByVal hKey As Long, _
ByVal lpSubKey As String, _
phkResult As Long) As Long
Private Declare Function RegQueryValueEx Lib "advapi32.dll" Alias "RegQueryValueExA" _
(ByVal hKey As Long, _
ByVal lpValueName As String, _
ByVal lpReserved As Long, _
lpType As Long, _
lpData As Any, _
lpcbData 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
( 較麻煩 )

' 2. 使用 Wsh ( Windows Scripting Host )
Dim WshShell As Object
Set WshShell = CreateObject("WScript.Shell") ' 建立 Wsh Shell 物件
MsgBox WshShell.RegRead("登錄檔機碼") ' 透過該物件 RegRead 方法 讀取登錄檔某機碼
