SAMPLE: RDS_Comp.exe Demonstrates How to Use the RDS.Dataspace Object from Client Script


View products that this article applies to.

Summary

Remote Data Services (RDS) is a technology that allows client-side Web applications to have database connectivity. With RDS, the user can make remote calls to an ActiveX DLL that is hosted on a Web service and can use the methods of that component to retrieve and update ADO recordsets. The remote access to the DLL is made through the RDS.Dataspace object.

RDS_Comp.exe is a sample in a self-extracting executable. This file contains files and sources that demonstrate how to use client-side script to retrieve an ADO Recordset from a remote Visual Basic component through the RDS.Dataspace object. The codes then shows how to bind this recordset to a client-side ActiveX control (specifically the Microsoft DataGrid control) and then submit the changes back through the server-side Visual Basic component to update the underlying data source.

Microsoft assumes that the user is familiar with Visual Basic, either VBScript or JScript, and also has some database development experience. The server-side code is written in Visual Basic, and the client-side code is script-embedded in the HTML page. Client code is demonstrated in both VBScript and JScript. The ADO recordset is bound to the Microsoft DataGrid control. However, this code may be modified to use other data-aware controls, as long as the controls support binding to an ADO recordset.

Microsoft also assumes that the user is running Microsoft Internet Information Server (IIS) 4.0 and has installed the Microsoft Data Access Components (MDAC) version 2.1 or later on the IIS server. To obtain the latest version of MDAC, see the following Microsoft Web site: NOTE: MDAC 2.5 is installed with Microsoft Windows 2000.

The ReadMe.txt file that is included in the self-extracting download has more detailed instructions on how to set up and run this sample.
