HTMLMailer Component
Properties Methods Events Configuration Settings Errors
The HTMLMailer Component is used to send HTML email including embedded images.
Syntax
nsoftware.IPWorks.Htmlmailer
Remarks
The component sends a message (provided in MessageHTML and MessageText). The HTML message may contain references to images which are automatically embedded into the message.
The MessageHTML property contains the HTML version of the message. The corresponding plain text version is provided into the MessageText property.
When MessageHTML is set, the component automatically computes a plaintext version of the text and puts it into MessageText. You may choose to override this default text with your own version.
The recipients are specified by the SendTo, Cc, and BCc properties, and the message subject by the Subject property.
Once all the appropriate properties have been set call the Send method and your message will be sent to its intended recipient(s).
Other SMTP headers may be specified through the OtherHeaders property. Information about interaction with the server is provided via the PITrail event.
