Folks
I have a VB app that refers to a DSN on my machine.
Is there a smart way of automating /creating this dsn on other peoples machines so I can pass them on my vb app.
Can I build something into the VB package to create this ?

Any help appreciated
Paul

Use these code sinppets to create/delete DSN from VB


      Option Explicit

      'Constant Declaration
      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


          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
                         

' Create DSN sample


     Dim intRet As Long
      Dim strDriver As String
      Dim strAttributes As String

      'Set the driver to SQL Server because it is most common.
      strDriver = "SQL Server"
      'Set the attributes delimited by null.
      'See driver documentation for a complete
      'list of supported attributes.
      strAttributes = "SERVER=SomeServer" & Chr$(0)
      strAttributes = strAttributes & "DESCRIPTION=Temp DSN" & Chr$(0)
      strAttributes = strAttributes & "DSN=DSN_TEMP" & Chr$(0)
      strAttributes = strAttributes & "DATABASE=pubs" & Chr$(0)
      'To show dialog, use Form1.Hwnd instead of vbAPINull.
      intRet = SQLConfigDataSource(vbAPINull, ODBC_ADD_DSN, _
      strDriver, strAttributes)

      If intRet Then
          MsgBox "DSN Created"
      Else
          MsgBox "Create Failed"
      End If



'Delete DSN Sample

      Dim intRet As Long
      Dim strDriver As String
      Dim strAttributes As String

      'Set the driver to SQL Server because most common.
      strDriver = "SQL Server"
      'Set the attributes delimited by null.
      'See driver documentation for a complete list of attributes.
      strAttributes = "DSN=DSN_TEMP" & Chr$(0)
      'To show dialog, use Form1.Hwnd instead of vbAPINull.
      intRet = SQLConfigDataSource(vbAPINull, ODBC_REMOVE_DSN, _
      strDriver, strAttributes)

      If intRet Then
          MsgBox "DSN Deleted"
      Else
          MsgBox "Delete Failed"
      End If

I see by using the above snippets, I can create a dsn that appears under the System DSN tab rather than the User DSN tab. Should I be concerned about that ?
The one I was looking to mimic was created in User DSN.

Also how would I set the verification piece ie.  
How Should SQL Server verify the authenticity of the Login ID
Choices are Windows NT or SQL Server

Thanks
Paul

Ps. I upped the points from 50 to 75
