Title: How can I send HTML messages with attachments (using Indy)
Question: With the Indy IdMessage component you can easily send an HTML formatted e-mails without attachments, or plain text e-mails with attachments, but how can you send HTML message WITH attachments...
Answer:
With the IdMessage component:
- You can send a plain text e-mail and add an attachment using:
TIdAttachment.Create(IdMessage.MessageParts, 'c:\attach.bmp');
- You can send an HTML formatted message simply by setting the IdMessage.body to the HTML string and the IdMessage.ContentType to 'text/html'
However if you try to combine these, i.e. send an HTML formatted message with an attachment you will find that the message is delivered with the HTML code shown as plain text.
This is because you have to send the HTML as a text part when sending attachments. So you need to create two text parts (one plain text and one HTML) and then add the attachments.
Here is some example code:
Notes:
IdMsgSend is a TIdMessage component
SMTP is a TIdSMTP component
Delphi 5, Indy version is v9.03 (Indy version which ships with D6 is 8.0)
var
idtTextPart:TIdText;
.
.
.
IdMsgSend. Clear;
IdMsgSend.ContentType := 'Multipart/Alternative';
// add a plain text message part
idtTextPart:=TIdText.Create(IdMsgSend.MessageParts,nil);
idtTextPart.ContentType:='text/plain';
idtTextPart.Body.Add('This is the plain part of the message.');
// add the HTML message part
idtTextPart:= TIdText.Create(IdMsgSend.MessageParts,nil);
idtTextPart.ContentType := 'text/html';
idtTextPart.Body.add('');
idtTextPart.Body.add('Testing...');
idtTextPart.Body.add('Testing...');
idtTextPart.Body.add('Testing...');
idtTextPart.Body.add('');
IdMsgSend.From.Address := 'me@mycompany.com';
IdMsgSend.From.Name := 'Me';
IdMsgSend.Sender.Address := 'me@mycompany.com';
IdMsgSend.Sender.Name := 'Me';
// add the recipients
IdMsgSend.Recipients.clear;
with IdMsgSend.Recipients.Add do Address := 'address1@somecompany.com';
with IdMsgSend.Recipients.Add do Address := 'address2@somecompany.com';
IdMsgSend.Subject := 'Some Subject';
// add an attachment
TIdAttachment.Create(IdMsgSend.MessageParts, 'c:\attach.bmp');
{SMTP Setup}
SMTP.Host := 'smtp.isp.com';
SMTP.Port := 25;
try
try
{now we send the message}
SMTP.Connect;
SMTP.Send(IdMsgSend);
except
on e: Exception do
ShowMessage(e.message);
end;
finally
SMTP.Disconnect;
end;
showmessage('Message Sent');
