    // See Global Unlock Sample for sample code.

    bool success;

    // Start with an empty MIME object...
    CkMime mime;

    // Initialize it as multipart/alternative.
    mime.NewMultipartAlternative();

    // Create a text/plain part.
    CkMime ptMime;
    ptMime.SetBodyFromPlainText("This is the plain text body.");
    strOut.append(ptMime.getMime());
    strOut.append("\r\n");
    strOut.append("****");
    strOut.append("\r\n");

    // The text/plain part looks like this:

    // 	Content-Type: text/plain
    // 	Content-Transfer-Encoding: 7bit
    // 
    // 	This is the plain text body.

    // Create a text/HTML part.
    CkMime htmlMime;
    htmlMime.SetBodyFromHtml("<html><body><p>This is the <b>HTML body</b></p></body></html>");
    strOut.append(htmlMime.getMime());
    strOut.append("\r\n");
    strOut.append("****");
    strOut.append("\r\n");

    // The text/html part looks like this:

    // 	Content-Type: text/html
    // 	Content-Transfer-Encoding: 7bit
    // 
    // 	<html><body><p>This is the <b>HTML body</b></p></body></html>

    // Add both parts as children of the multipart/alternative
    mime.AppendPart(ptMime);
    mime.AppendPart(htmlMime);
    strOut.append(mime.getMime());
    strOut.append("\r\n");

    // This the result.  The boundary string was automatically generaetd.
