Tantalus story is terrible... perhaps this is a little less 'dramatic' :)

You are right.

But similarity isn't quite painful ?

I think we have to use -m option in the following sample given in tipmmail.prg. I am sure, you might have checked this already. I had not compiled and tested though. :(

Code: Select all

/*
 * $Id: tipmmail.prg 8751 2008-06-19 00:02:50Z vszakats $
 */

/******************************************
* TIP test
* Mail - reading and writing multipart mails
*
* Creating a mail message.
* This will create a valid mail message, using
* the set of files given in the command line.
*
* Usage:
* testmmail [options] attachment1, attachment2...
*  options:
*    -h              Help
*    -f "from"       Set "mail from" field
*    -t "to"         Set "mail to" field
*    -s "subject"    Set mail subject
*    -b "body"       Set mail body (or message)
*    -m "bodyfile"   Set mail body using a file
*
*
* This test writes data to standard output, and is
* compiled only under GTCGI;

Yes, but it does not provide information about how the connection is established.

I've found in hbtip files 'sendmail.prg' it has a function 'hb_sendmail' and I've made it work.

It allows to send html messages and you can attach files, but the problem is how to relate an attached images with html body.

Roberto.

Did you try with Mht files ( all in there ) instead of Htm ?

This is from another forum. I don't know if it helps you or not.

how to embed image in HTML ?

Depends on how you're trying to do it, but your mail composing program will need a way to send multipart/mime messages. The image is converted to base64 and the data sent by the mailer looks something like:

Code: Select all

From: foo1atbar.net
To: foo2atbar.net
Subject: A simple example
Mime-Version: 1.0
Content-Type: multipart/related; boundary="boundary-example"; type="text/html"

--boundary-example
Content-Type: text/html; charset="US-ASCII"

... text of the HTML document, which might contain a URI
referencing a resource in another body part, for example
through a statement such as:
<IMG SRC="cid:foo4atfoo1atbar.net" ALT="IETF logo">

--boundary-example
Content-Location: CID:somethingatelse ; this header is disregarded
Content-ID: <foo4atfoo1atbar.net>
Content-Type: IMAGE/GIF
Content-Transfer-Encoding: BASE64

R0lGODlhGAGgAPEAAP/////ZRaCgoAAAACH+PUNv
cHlyaWdodCAoQykgMTk5LiBVbmF1dGhvcml6ZWQgZHV
wbGljYXRpb24gcHJvaGliaXRlZC4A etc...

--boundary-example--

Note how the HTML code in the first part includes <img src="cid:foo.." the CID means that it's to look in another part of the multipart message.

Thanks, it appears to be useful.

I'll review it.

Anyway, I've solved the problem via the 'hard way'.

I've created the message using Outlook, saving it in '.eml' format, and then programmatically doing changes required in that file for different situations.

Very hard, but works...

Roberto.
