You are trying to add a design-time control to an ASP or HTML page, but the control requires the Microsoft® Visual InterDev™ Scripting Object Model. For example, you are trying to add a Recordset control to an ASP page.
To enable the Scripting Object Model for a page when you first create the page, right-click on the page, choose the Properties command, and check the Enable scripting object model button in the ASP Settings group on the General tab of the page's property pages.
For more information, see The Scripting Object Model.
