CreateObject Method (RDS)

Creates the proxy for the target business object and returns a pointer to it. The proxy packages and marshals data to the server-side stub for communications with the business object to send requests and data over the Internet. For in-process component objects, no proxies are used, just a pointer to the object is provided.

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.

Syntax

Remote Data Service supports the following protocols: HTTP, HTTPS (HTTP over Secure Socket Layer), DCOM, and in-process.

Protocol Syntax
HTTP Set object = DataSpace.CreateObject("ProgId", "https://awebsrvr")
HTTPS Set object = DataSpace.CreateObject("ProgId", "https://awebsrvr")
DCOM Set object = DataSpace.CreateObject("ProgId", "computername")
In-process Set object = DataSpace.CreateObject("ProgId", "")

Parameters

Object
An object variable that evaluates to an object that is the type specified in ProgID.

DataSpace
An object variable that represents an RDS.DataSpace object used to create an instance of the new object.

ProgID
A String value that contains the programmatic identifier specifying a server-side business object that implements your application's business rules.

awebsrvr or computername
A String value that represents a URL identifying the Internet Information Services (IIS) Web server where an instance of the server business object is created.

Remarks

The HTTP protocol is the standard Web protocol; HTTPS is a secure Web protocol. Use the DCOM protocol when running a local-area network without HTTP. The in-process protocol is a local dynamic-link library (DLL); it does not use a network.
