• ActiveX Data Objects (ADO), versions 1.0, 1.5, 2.0, 2.1 SP2

SUMMARY

This article demonstrates how to prompt a user for ODBC connect string information such as Server, User ID, Password, Trusted_Connection, Language, and Database using ActiveX Data Objects (ADO).

The article also shows how to display an OLE DB Data Link dialog box to select an OLEDB provider and its properties.

MORE INFORMATION

ODBC Connect String

1. In Visual Basic 6.0, add a project reference to the Microsoft ActiveX Data Objects Library.



2. Paste the following code into the Sub Form_Load() section of a new form or another place in your Visual Basic code:




      Dim conn As ADODB.Connection
      Dim strConn As String

      ' Assign the connection string to a variable.

      strConn = "DRIVER={SQL Server};SERVER=;UID=;PWD=;DATABASE="

      ' Create the Connection object.
      Set conn = New ADODB.Connection

      'Assign the connection string and provider, then open the connection.
      With conn
        .ConnectionString = strConn
        .Provider = "MSDASQL"
      ' Valid Enums for the ADO Prompt property are:
      ' adPromptAlways = 1
      ' adPromptComplete = 2
      ' adPromptCompleteRequired = 3
      ' adPromptNever =4
        .Properties("Prompt") = adPromptAlways
        .Open strConn
      End With 

OLEDB Data Link Dialog Box

1. Set project references to the Microsoft OLE DB Service Component 1.0 Type Library and Microsoft ActiveX Data Objects Library.



2. Use the following code to open a data link dialog box and print the connection string in the immediate window:




      Private Sub btnRunTest_Click()
      Dim conn As New ADODB.Connection
      Dim dl As New MSDASC.DataLinks

      conn = dl.PromptNew
      Debug.print conn.ConnectionString

      End Sub
