//  Create a MailMan or Imap object first for the purpose
//  of unlocking the component. (Only one is necessary)
Chilkat.MailMan mailman = new Chilkat.MailMan();
mailman.UnlockComponent("anything for 30-day trial");
Chilkat.Imap imap = new Chilkat.Imap();
imap.UnlockComponent("anything for 30-day trial");

Chilkat.Email email = new Chilkat.Email();

//  Load an email object containing attachments.
//  This .eml can be downloaded from:
//  http://www.example-code.com/testData/HtmlEmail.eml
bool success;
success = email.LoadEml("HtmlEmail.eml");
if (success != true) {
    MessageBox.Show(email.LastErrorText);
    return;
}

//  List the attachment filenames:
//  This email has two attachments: logo.jpg and faxCover.doc
int i;
for (i = 0; i <= email.NumAttachments - 1; i++) {
    textBox1.Text += email.GetAttachmentFilename(i) + "\r\n";
    textBox1.Refresh();
}

//  Let's say we want to save the 1st attachment as "pic.jpg",
//  and the 2nd attachment as "cover.doc".
//  Call SetAttachmentFilename for both:
email.SetAttachmentFilename(0,"pic.jpg");
email.SetAttachmentFilename(1,"cover.doc");

//  The SaveAttachedFile method allows you to specify the directory
//  where the attachment is saved.  To save to the current working
//  directory, pass a "." for the directory path.  This code
//  saves each attachment to the current working directory:
email.SaveAttachedFile(0,".");
email.SaveAttachedFile(1,".");

//  Alternatively, we could save all the attachments in a single
//  call.  The argument to SaveAllAttachments is the directory
//  path.  In this case, the filenames set by SetAttachmentFilename
//  are used:
email.SaveAllAttachments("myAttachments");

MessageBox.Show("Finished!");
