HELP!,

I am trying to automatically configure the Oracle ODBC data source from Visual Basic5.  I can set up a basic data source but cannot find the syntax required to load the SQl*Net Connect String.  I am currently using the following code
'Decalrations Used to Generate EUP DSN
Private Const ODBC_ADD_DSN = 1 ' Add data source
Private Const ODBC_CONFIG_DSN = 2 ' Configure (edit) data source
Private Const ODBC_REMOVE_DSN = 3 ' Remove data source
Private Const vbAPINull As Long = 0& ' NULL Pointer
#If Win32 Then
    Private Declare Function SQLConfigDataSource Lib "ODBCCP32.DLL" _
    (ByVal hwndParent As Long, ByVal fRequest As Long, _
     ByVal lpszDriver As String, ByVal lpszAttributes As String) _
     As Long
#Else
     Private Declare Function SQLConfigDataSource Lib "ODBCINST.DLL" _
     (ByVal hwndParent As Integer, ByVal fRequest As Integer, ByVal _
     lpszDriver As String, ByVal lpszAttributes As String) As Integer
#End If

    #If Win32 Then
        Dim intRet As Long
    #Else
        Dim intRet As Integer
    #End If
    Dim strDriver As String
    Dim strAttributes As String

   strDriver = "Oracle73 Ver 2.5"
    strAttributes = "SQL*Net Connect String=EUP" & Chr$(0)
    strAttributes = strAttributes & "DESCRIPTION=Europa Connection (EUP)" & Chr$(0)
    strAttributes = strAttributes & "DSN=EUP" & Chr$(0)
   
    intRet = SQLConfigDataSource(vbAPINull, ODBC_ADD_DSN, _
             strDriver, strAttributes)

Try this, it works on my computer

Public Sub CreateDSN()

   Dim intRet        As Long
   Dim strDriver     As String
   Dim strAttributes As String
   
   strDriver = "Oracle73 Ver 2.5"
   strAttributes = "Server=EUP" & Chr$(0)
   strAttributes = strAttributes & "DESCRIPTION=Europa Connection (EUP)" & Chr$(0)
   strAttributes = strAttributes & "DSN=EUP" & Chr$(0)
   
   intRet = SQLConfigDataSource(vbAPINull, ODBC_ADD_DSN, strDriver, strAttributes)

End Sub

You know, you could also use the following code and it works too, but without any API

Public Sub CreateDSN(sDSN As String)

   Dim nRet                As Long
   Dim sDriver             As String
   Dim sAttributes         As String
   
   
   strDriver = "Oracle73 Ver 2.5"
   strAttributes = "Server=EUP" & Chr$(0)
   strAttributes = strAttributes & "DESCRIPTION=Europa Connection (EUP)" & Chr$(0)
   strAttributes = strAttributes & "DSN=EUP" & Chr$(0)
   
   DBEngine.RegisterDatabase sDSN, strDriver, True, strAttributes
   
End Sub
