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.
