DEVELOPING COLDFUSION 9 APPLICATIONS
Using Web Elements and External Objects
Several examples in this documentation use this object.
Note: CDO is installed by default on all Windows NT and 2000 operating systems that have installed the Microsoft SMTP
server. In Windows NT Server environments, the SMTP server is part of the Option Pack 4 setup. In Windows 2000 Server
and Workstation environments, it is bundled with the operating system.
note. >>>The CDO for NTS NewMail component includes methods and properties to perform a wide range of mail-
handling tasks. (In the OLE/COM Object Viewer, methods and properties can be grouped, so you could find it difficult
to distinguish between them at first.)
The CDO for NTS NewMail object includes the following properties:
Body [ String ]
Cc[ String ]
From[ String ]
Importance[ Long ]
Subject[ String ]
To[ String ]
You use these properties to define elements of your mail message. The CDO for NTS NewMail object also includes a
method which has optional arguments to send messages.

Setting properties and executing methods
The following example, which uses the sample Mailer COM object, shows how to assign properties to your mail
message and how to execute component methods to handle mail messages.
In the example, form variables contain the method parameters and properties, such as the name of the recipient, the
desired e-mail address, and so on:

Description
An in-process server object (typically a DLL) that is running in the same process space as the calling
process, such as ColdFusion.
An out-of-process server object (typically an EXE file) that is running outside the ColdFusion process space
but running locally on the same server.
An out-of-process server object (typically an EXE file) that is running remotely on the network. If you
