    // This example requires the Chilkat API to have been previously unlocked.
    // See Global Unlock Sample for sample code.

    mime := chilkat.NewMime()

    success := mime.SetBodyFromFile("VoiceMessage.wav")
    if success == false {
        fmt.Println(mime.LastErrorText())
        mime.DisposeMime()

    }

    // The MIME has this header:
    // Content-Disposition: attachment;
    // 	 filename="VoiceMessage.wav"
    // Content-Transfer-Encoding: base64
    // Content-Type: audio/x-wav;
    // 	name="VoiceMessage.wav"

    // We don't want the content-disposition to be an
    // attachment -- otherwise the email object will self-correct
    // and put it in a multipart/mixed format...

    // Now load it into an email object:

    success = email.SetFromMimeText(*strMime)
    if success == false {
        fmt.Println(email.LastErrorText())
        mime.DisposeMime()

    email.SetSubject("This is a test")
    email.SetFrom("support@chilkatsoft.com")

    // Your email is ready to send.
    // (but for this example, we'll simply save it to a file...)
