save email attachments using Thunderbird source

Question

I would like to save email attachments using thunderbird source code. I got the following code in your forums..but its not working

    alert("Messages selected: " + gFolderDisplay.selectedCount);
      let enumerator = gFolderDisplay.selectedMessages;
        for each (let msgHdr in fixIterator(enumerator, Ci.nsIMsgDBHdr)) {
          var messageID = msgHdr.messageId;
           alert("MessageID: " + messageID);
           var subject = msgHdr.mime2DecodedSubject;
          alert("Subject: " + subject);
            MsgHdrToMimeMessage(msgHdr, null, function (aMsgHdr, aMimeMsg) {
              try {
        alert("Size of the message: " + aMimeMsg.size);
            alert("Structure of the message:\n" + aMimeMsg.prettyString(true, undefined, true));
             let attachments = aMimeMsg.allUserAttachments || aMimeMsg.allAttachments;
             alert("Number of attachments: " + attachments.length);
                   for (let [index, att] in Iterator(attachments))
        {
            alert ("URL: " + att.url  + " Name: " + att.name);
            let ioService = Cc["@mozilla.org/network/io-service;1"].getService(Ci.nsIIOService);  
            let neckoURL = null;  
            neckoURL = ioService.newURI(att.url, null, null);  
            neckoURL.QueryInterface(Ci.nsIMsgMessageUrl);  
            let uri = neckoURL.uri;  
            let attInfo = new AttachmentInfo(att.contentType, att.url, att.name, uri, att.isExternal);
            attInfo.save();
        }
    } catch (err) {
        alert(err);
    }
}, true, { examineEncryptedParts: true, });
}

Using above code i can able to go through the selected messages.but not saving the attachments.its showing number of attachments. And also i would like to set my own labels for the selected mails. How i can i achieve this? Please help me out... Thanks in advance

You should at least show that you've made some effort trying to understand the failure. Where is the code failing exactly? What are the values of "[index, att]" for each iteration of the loop? Which error messages do you get in the error console? — Jonathan Protzenko, Apr 16 '13 at 12:51

working code

      var enumerator = gFolderDisplay.selectedMessages;
        for each (var msgHdr in fixIterator(enumerator, Components.interfaces.nsIMsgDBHdr)) {
        msgHdr.setStringProperty("docuHive","dhivelabel");

            MsgHdrToMimeMessage(msgHdr, null, function (aMsgHdr, aMimeMsg) {
              try {
             var attachments = aMimeMsg.allUserAttachments || aMimeMsg.allAttachments;
                   for (var [index, att] in Iterator(attachments))
        {
            var ioService = Components.classes["@mozilla.org/network/io-service;1"].getService(Components.interfaces.nsIIOService);  
            var neckoURL = null;  
            neckoURL = ioService.newURI(att.url, null, null);  
            neckoURL.QueryInterface(Components.interfaces.nsIMsgMessageUrl);  
            var uri = neckoURL.uri;  
            var attInfo = new AttachmentInfo(att.contentType, att.url, att.name, uri, att.isExternal); 
            // getting the chrome directory
            var file = Components.classes["@mozilla.org/file/directory_service;1"].
           getService(Components.interfaces.nsIProperties).
           get("AChrom", Components.interfaces.nsIFile);

           var msguri = msgHdr.folder.getUriForMsg(msgHdr);

    messenger = Components.classes["@mozilla.org/messenger;1"]
                       .createInstance(Components.interfaces.nsIMessenger);
                       alert(messenger);
        messenger.saveAttachmentToFolder(att.contentType,att.url,"attachmentname.extension",msguri,file);

        }
    } catch (err) {
        alert(err);
    }
}, true, { examineEncryptedParts: true, });
}
