Version Property Example (VB)

  • Άρθρο

This example uses the Version property of a Connection object to display the current ADO version. It also uses several dynamic properties to show:

  • the current DBMS name and version.

  • OLE DB version.

  • provider name and version.

  • ODBC version.

  • ODBC driver name and version.

'BeginVersionVB  
Public Sub Main()  
    On Error GoTo ErrorHandler  
  
    Dim Cnxn As ADODB.Connection  
    Dim strCnxn As String  
    Dim strVersionInfo As String  
  
    ' Open connection  
    Set Cnxn = New ADODB.Connection  
    strCnxn = "Provider='sqloledb';Data Source='MySqlServer';" & _  
        "Initial Catalog='Pubs';Integrated Security='SSPI';"  
    Cnxn.Open strCnxn  
  
    strVersionInfo = "ADO Version: " & Cnxn.Version & vbCr  
    strVersionInfo = strVersionInfo & "DBMS Name: " & Cnxn.Properties("DBMS Name") & vbCr  
    strVersionInfo = strVersionInfo & "DBMS Version: " & Cnxn.Properties("DBMS Version") & vbCr  
    strVersionInfo = strVersionInfo & "OLE DB Version: " & Cnxn.Properties("OLE DB Version") & vbCr  
    strVersionInfo = strVersionInfo & "Provider Name: " & Cnxn.Properties("Provider Name") & vbCr  
    strVersionInfo = strVersionInfo & "Provider Version: " & Cnxn.Properties("Provider Version") & vbCr  
  
    MsgBox strVersionInfo  
  
    ' clean up  
    Cnxn.Close  
    Set Cnxn = Nothing  
    Exit Sub  
  
ErrorHandler:  
    ' clean up  
    If Not Cnxn Is Nothing Then  
        If Cnxn.State = adStateOpen Then Cnxn.Close  
    End If  
    Set Cnxn = Nothing  
  
    If Err <> 0 Then  
        MsgBox Err.Source & "-->" & Err.Description, , "Error"  
    End If  
End Sub
