ODBC connection to SQL server using LotusScript

You can create an ODBC connection to a SQL server using LotusScript with the click of a button. I put this button in my About Database document.

  
Code: Option Explicit

Private Const REG_SZ = 1    
'Constant for a string variable type.
Private Const HKEY_LOCAL_MACHINE = 
&H80000002
Declare Function RegCreateKey Lib "advapi32.dll"
 Alias "RegCreateKeyA" (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 RegCloseKey Lib "advapi32.dll" 
(Byval hKey As Long) As Long

Sub Click(Source As Button)
 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
 Dim Password As String
 
 Dim lResult As Long
 Dim hKeyHandle As Long
 
   'Specify the DSN parameters.
 
 DataSourceName = "<the name of your new DSN>" 
 DatabaseName = "<name of the database to 
be accessed by the new 
DSN>"  
 Description = "<a description of the new DSN>"   
 'DriverPath = ""     'Optional <path to your 
SQL Server driver>
 LastUser = "<default user ID of the new DSN>"    
 Password = "<Password>"
 Server = "'<name of the server to be 
accessed by the new DSN>"    
 DriverName = "SQL Server"
 
   'Create the new DSN key.
 
 lResult = RegCreateKey(HKEY_LOCAL_MACHINE,
 "SOFTWAREODBCODBC.INI" & _
 DataSourceName, hKeyHandle)
 
   'Set the values of the new DSN key.
 
 lResult = RegSetValueEx(hKeyHandle, 
"Database", 0&, REG_SZ, _
 Byval DatabaseName, Len(DatabaseName))
 lResult = RegSetValueEx(hKeyHandle,
 "Description", 0&, REG_SZ, _
 Byval Description, Len(Description))
 lResult = RegSetValueEx(hKeyHandle, 
"Driver", 0&, REG_SZ, _
 Byval DriverPath, Len(DriverPath))
 lResult = RegSetValueEx(hKeyHandle, 
"LastUser", 0&, REG_SZ, _
 Byval LastUser, Len(LastUser))
 lResult = RegSetValueEx(hKeyHandle,
 "Server", 0&, REG_SZ, _
 Byval Server, Len(Server))
 
   'Close the new DSN key.
 
 lResult = RegCloseKey(hKeyHandle)
 
   'Open ODBC Data Sources key to list the 
new DSN in the ODBC Manager.
   'Specify the new value.
   'Close the key.
 
 lResult = RegCreateKey(HKEY_LOCAL_MACHINE, _
 "SOFTWAREODBCODBC.INIODBC Data Sources", 
hKeyHandle)
 lResult = RegSetValueEx(hKeyHandle,
DataSourceName, 0&, REG_SZ, _
 Byval DriverName, Len(DriverName))
 lResult = RegCloseKey(hKeyHandle)
 
End Sub

MEMBER FEEDBACK TO THIS TIP

The author seems to have lost some backslashes in the RegCreateKey function. The following lines:

lResult = RegCreateKey(HKEY_
LOCAL_MACHINE,
 "SOFTWAREODBCODBC.INI" & _
 DataSourceName, hKeyHandle)

should be:

 lResult = RegCreateKey
(HKEY_LOCAL_MACHINE,
 "SOFTWARE\
ODBC\ODBC.INI" & _
 DataSourceName, hKeyHandle)

And also, the following lines:

lResult = RegCreateKey(HKEY_
LOCAL_MACHINE, _
 "SOFTWAREODBCODBC.INIODBC 
Data Sources", 
hKeyHandle)

should be:

lResult = RegCreateKey
(HKEY_LOCAL_MACHINE, _
 "SOFTWARE\ODBC
\ODBC.INI\ODBC 
Data Sources", 
hKeyHandle)
