As some of you may laugh about, I am using the puny winsock control to make an email client.  What I want to know is, how can I add a "file attachment" capability?

You have do write the encoding routine for this yourself. unless you
want to use one of the SMTP controls such as the free one from

I would recommend you get this and try it to see how it works. It is
extremely easy to use.

There is also the more complicated, but probably much more powerful
solution from

Thanks!  That's a really cool control!

  All data sent in email must be text, not binary.  As a result,
  attachments are sent by using one of a number of encoding schemes (the
  Apple BinHex is one of the most common) to torn the file into a text
  string. This is added to the body of the email. The email clients
  automatically identify this encoded attachment and hide it when you
  are viewing the body of an email message.

As an alternative to the winsock control we offer a freeware control
called SocketWrench which can be used to create both client and server
applications including e-mail clients.  We also offer a MIME and SMTP
control as part of our commercial SocketTools Visual Edition package.
Please see the following SocketTip from our website demonstrating the
use of these controls:
