RDSIE3.DataSpace Object

The RDSIE3.DataSpace object creates client-side proxies to custom business objects located on the middle tier.

Method

CreateObject

Remarks

Microsoft® Remote Data Service needs business object proxies so that client-side components can communicate with business objects located on the middle tier. Proxies facilitate the packaging, unpackaging, and transport (marshaling) of the application's recordset data across process or machine boundaries.

Remote Data Service uses the RDSIE3.DataSpace object's CreateObject method to create business object proxies. The business object proxy is dynamically created whenever an instance of its middle-tier business object counterpart is created. Remote Data Service supports the following protocols: HTTP, HTTPS (HTTP Secure Sockets), DCOM, and in-process (client components and the business object reside on the same computer).

The RDSIE3.DataSpace object has two class IDs:

• A class ID that you should use for Web pages that use all single-threaded ActiveX controls: 99586D40-DB60-11CF-9D87-00AA00B91181. This is the default class ID.
  
  
• A class ID that you should use for Web pages that use apartment model ActiveX controls (which will be available in the near future): FD10ACC0-1E01-11D0-9662-00AA00B8E0EA.
