ReadyState Property Example (VBScript)

  • Article

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.

The following example shows how to read the ReadyState property of the RDS.DataControl object at run time in VBScript code. ReadyState is a read-only property.

To test this example, cut and paste this code between the <Body> and </Body> tags in a normal HTML document and name it RDSReadySt.asp. Use Find to locate the file Adovbs.inc and place it in the directory you plan to use. ASP script will identify your server.
