给你个例子看看:
'注册表的操作

Option Explicit
Const HKEY_CLASSES_ROOT = &H80000000
Const HKEY_CURRENT_USER = &H80000001
Const HKEY_LOCAL_MACHINE = &H80000002
Const HKEY_USERS = &H80000003
Const HKEY_PERFORMANCE_DATA = &H80000004
Const HKEY_CURRENT_CONFIG = &H80000005
Const HKEY_DYN_DATA = &H80000006
Const REG_NONE = 0
Const REG_SZ = 1
Const REG_EXPAND_SZ = 2
Const REG_BINARY = 3
Const REG_DWORD = 4
Const REG_DWORD_BIG_ENDIAN = 5
Const REG_MULTI_SZ = 7

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 RegCreateKey Lib "advapi32.dll" Alias "RegCreateKeyA" (ByVal hKey As Long, ByVal lpSubKey As String, phkResult As Long) As Long


Private Sub Command1_Click()
Dim hKey As Long
Dim DSNName, strDriver, strServer, strDatabase, strLastUser, strDBType As String

DSNName = "myodbc"

strDriver = "C:\\WINNT\\System32\\sqlsrv32.dll" 'SQL Server的驱动,如果用VFP可以改成相应的文件
strServer = "SERVER"
strDatabase = "test"
strLastUser = "sa"
strDBType = "SQL Server"

RegCreateKey HKEY_LOCAL_MACHINE, "SOFTWARE\ODBC\ODBC.INI\ODBC Data Sources", hKey
RegSetValueEx hKey, DSNName, 0, REG_SZ, ByVal strDBType, Len(strDBType) + 1

RegCreateKey HKEY_LOCAL_MACHINE, "SOFTWARE\ODBC\ODBC.INI\" & DSNName, hKey
RegSetValueEx hKey, "Driver", 0, REG_EXPAND_SZ, ByVal CStr(strDriver), Len(strDriver) + 1
RegSetValueEx hKey, "Server", 0, REG_SZ, ByVal CStr(strServer), Len(strServer) + 1
RegSetValueEx hKey, "Database", 0, REG_SZ, ByVal CStr(strDatabase), Len(strDatabase) + 1
RegSetValueEx hKey, "LastUser", 0, REG_SZ, ByVal CStr(strLastUser), Len(strLastUser) + 1
End Sub

用getsetting函数
GetSetting(appname, section, key[, default])
appname 必要。字符串表达式，包含应用程序或工程的名称，要求这些应用程序或工程有注册表项设置。
section 必要。字符串表达式，包含区域名称，要求该区域有注册表项设置。
key 必要。字符串表达式，返回注册表项设置的名称。
default 可选。表达式，如果注册表项设置中没有设置值，则返回缺省值。如果省略，则 default 取值为长度为零的字符串 ("")。
