DataSpace 对象和 CreateObject 方法范例 (VBScript)

以下范例显示如何使用具有默认业务对象 RDSServer.DataFactory 的 RDS.DataSpace 的 CreateObject 方法。要测试该范例，请将其剪切并粘贴到标准 HTML 文档的 <Body></Body> 标记之间，然后将其命名为 ADCapi8.asp。ASP 脚本将标识服务器。

<H4>Click Run. The CreateObject Method of the RDS.DataSpace Object Creates an instance of the RDSServer.DataFactory. 
The Query Method of the RDSServer.DataFactory is used to bring back a Recordset. </H4>

<Script Language="VBScript">

Dim ADF
Dim strServer
Dim strConnect
Dim strSQL
strServer = "http://<%=Request.ServerVariables("SERVER_NAME")%>"

strSQL = "Select * from Employee"Sub Run_OnClick()
   Dim objADORs      '创建 Recordset 对象
Set ADF = ADS1.CreateObject("RDSServer.DataFactory", strServer)            '获取 Recordset   
Set objADORs = ADF.Query(strConnect, strSQL)

</Script>

以下范例显示如何使用 CreateObject 方法创建自定义业务对象 VbBusObj.VbBusObjCls 的实例。该范例还使用 Active Server Pages 脚本标识 Web 服务器名。要查看完整的范例，请通过范例应用程序的选择器，在“客户端层”列中选择“VBScript in Internet Explorer”，并在“中间层”列中选择“自定义 Visual Basic 业务对象”。

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
