Title: Send email in console mode
Question: How can I Send email in console mode?
Answer:
You can use this unit for do it :
unit mapimail;
// --------------------------------------------------------------
// Simple wrapper for Simple MAPI. Sends an email with an
// optional file attachment using the client's MAPI client, e.g.
// Outlook or NS Communicator. Very simple implementation
// limited to one target and one attachment.
// --------------------------------------------------------------
interface
uses
sysutils, dialogs, forms, Windows, MAPI;
type
tMailFileException = class( Exception );
const
ERROR = 'Unable to send email message.' + #10#10 + 'Reason: %s.';
function sendMail( const TargetName, TargetAddr,
SenderName, SenderAddr,
MsgSubject, MsgContent,
Attachment : String;
PreviewMsg : Boolean = TRUE ) : Integer;
function getMAPIError( intErrorCode : Integer ) : String;
