二、程序源代码 首先在工程中添加一个标准模块并输入如下代码，这 些代码用于注册表操作： ’声明必要的API函数及常量 Declare Function RegSaveKey Lib "advapi32.dll" Alias "RegSaveKeyA" (ByVal hKey As Long, ByVal lpFile As String, ByVal lpSecurityAttributes As Long) As Long Declare Function RegSetValue Lib "advapi32.dll" Alias "RegSetValueA" (ByVal hKey As Long, ByVal lpSubKey As String, ByVal dwType As Long, ByVal lpData As String, ByVal cbData As Long) As Long Declare Function RegCloseKey Lib "advapi32.dll" (ByVal hKey As Long) As Long Declare Function RegCreateKey Lib "advapi32.dll" Alias "RegCreateKeyA" (ByVal hKey As Long, ByVal lpSubKey As String, phkResult As Long) As Long Declare Function RegDeleteKey Lib "advapi32.dll" Alias "RegDeleteKeyA" (ByVal hKey As Long, ByVal lpSubKey As String) As Long Declare Function RegDeleteValue Lib "advapi32.dll" Alias "RegDeleteValueA" (ByVal hKey As Long, ByVal lpValueName As String) As Long Declare Function RegOpenKey Lib "advapi32.dll" Alias "RegOpenKeyA" (ByVal hKey As Long, ByVal lpSubKey As String, phkResult As Long) As Long 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 Declare Function RegOpenKeyEx Lib "advapi32.dll" Alias "RegOpenKeyExA" (ByVal hKey As Long, ByVal lpSubKey As String, ByVal ulOptions As Long, ByVal samDesired As Long, phkResult As Long) As Long Public Const HKEY_CLASSES_ROOT = &H80000000 Public Const HKEY_CURRENT_USER = &H80000001 Public Const HKEY_LOCAL_MACHINE = &H80000002 Public Const HKEY_USERS = &H80000003 Public Const ERROR_NO_MORE_ITEMS = 259& Public Const HKEY_CURRENT_CONFIG = &H80000005 Enum ValueType REG_NONE = 0 REG_SZ = 1 REG_EXPAND_SZ = 2 REG_BINARY = 3 REG_DWORD = 4 REG_DWORD_BIG_ENDIAN = 5 REG_MULTI_SZ = 7 End Enum Global Const KEY_ALL_ACCESS = &H3F Dim lngtype As Long Dim rtn As Long, lBuffer As Long, sbuffer As String Dim lBufferSize As Long ’新建主键的过程进入讨论组讨论。
