Creating a Message

[This is preliminary documentation and subject to change.]

To begin building a new message, first create an instance of the Message COM class, as shown in the following example:

' Reference to Microsoft ActiveX Data Objects 2.5 Library
' Reference to Microsoft CDO for Exchange 2000 Server Library
Dim iMsg as new CDO.Message

#import "c:\program files\common files\system\ado\msado15.dll" no_namespace
#import "c:\exchsrvr\cdoex.dll" no_namespace
// ...
MessagePtr iMsg(__uuidof(Message));

Dim iMsg
Set iMsg = CreateObject("CDO.Message")

You can create and send or post a simple message using only the IMessage interface.

• To send an SMTP message, you must at least set the To and From properties on the IMessage interface.
• To post an NNTP message, you must at least set the IMessage.Newsgroups and IMessage.Subject properties.
• To send or post multiple messages efficiently, create a single Message object and reuse it for each message.
• To send individual messages with the same content to many recipients, change the address and call the IMessage.Send or IMessage.Post method for each message.
• To send different content in each message, use the IBodyParts.DeleteAll method to clear all of the body parts associated with a Message object.
