1. Open a new Visual Basic project. Form1 is created by default. Put a CommandButton on Form1 (Command1), and put the following code in the General Declarations section of the code for Form1: Option Explicit
Private Const REG_SZ = 1 'Constant for a string variable type. Private Const HKEY_LOCAL_MACHINE = &H80000002
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 RegCloseKey Lib "advapi32.dll" _ (ByVal hKey As Long) As Long
2. Place the following code in the click event of the Command1 button on Form1:
Change the values of the DataSourceName, DatabaseName, Description, DriverPath, LastUser, and Server variables as appropriate for your environment. Any of the drivers listed on the ODBC Drivers tab of the ODBC Data Source Administrator window can be used as part of the DriverPath variable. All of these drivers can be found in C:\Windows\System for Windows 95 or Windows 98 machines and C:\Winnt\System32 for Windows NT.
Private Sub Command1_Click()
Dim DataSourceName As String Dim DatabaseName As String Dim Description As String Dim DriverPath As String Dim DriverName As String Dim LastUser As String Dim Regional As String Dim Server As String
