The following example shows how to use the CreateObject method to create an instance of a custom business object, VbBusObj.VbBusObjCls. It also uses the Active Server Pages scripting to identify the Web server name.

To see the complete example, open the sample applications selector. In the Client Tier column, select VBScript in Internet Explorer. In the Middle Tier column, select Custom Visual Basic Business Object.


Sub Window_OnLoad()
   strServer = "http://<%=Request.ServerVariables("SERVER_NAME")%>"
   Set BO = ADS1.CreateObject("VbBusObj.VbBusObjCls", strServer)
   txtConnect.Value = "dsn=Pubs;uid=MyUserId;pwd=MyPassword;"
   txtGetRecordset.Value = "Select * From authors for Browse"
End Sub
