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, choose "VBScript in Internet Explorer" in the Client Tier column and "Custom Visual Basic Business Object" in the Middle Tier column from the sample applications selector.

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