The following example shows how to use the CreateObject method of the RDS.DataSpace with the default business object, RDSServer.DataFactory. To test this example cut and paste this code between the <Body></Body> tags in a normal HTML document and name it ADCapi8.asp. ASP script will identify your server.

The following example shows how to use the CreateObject method to instantiate 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 ôVBScript in Internet Explorerö in the Client Tier column and ôCustom Visual Basic Business Objectö 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
