CreateTextHtml method is a one-line-command that can be
used in your applications to create email message that has
two parts: text/plain part and
text/html part. Message will not be
sent. You can add attachments if needed using
Message.Attach
method. You can also change message headers, or any other
field necessary.
It is not required to use CreateTextHtml method to send
such message - you can create similar message from scratch
using appropriate properties and methods. By using this
method, wodSmtp creates 'template' message and puts
appropriate values to appropriate parts.
To finally send the message, use SendMessage
method.
