DataFactory Object, Query Method, and CreateObject Method Example (VBScript)

Important

Beginning with Windows 8 and Windows Server 2012, RDS server components are no longer included in the Windows operating system (see Windows 8 and Windows Server 2012 Compatibility Cookbook for more detail). RDS client components will be removed in a future version of Windows. Avoid using this feature in new development work, and plan to modify applications that currently use this feature. Applications that use RDS should migrate to WCF Data Service.

This example creates an RDSServer.DataFactory object using the CreateObject method of the RDS.DataSpace object. To test this example, cut and paste this code between the <Body> and </Body> tags in a normal HTML document and name it DataFactoryVBS.asp. ASP script will identify your server.
