update display picture for contact

[xuefeng wang]

I am trying to get the display picture for the user following the example given by the MsnObjectMessenger example. I was able to get the display picture for the first run. However, if the contact update the display picture, how I would know about this.

Is there a way to get a notification from the server when the user contact changes its display picture?

Please help. Thanks

Yes it is possible. Sample Code for you :

@Override
            public void contactStatusChanged(MsnMessenger messenger, MsnContact msnContact) {
                System.out.println("Contact :" + msnContact.getEmail() + "Status Changed To:"
                        + msnContact.getStatus() + " Old Status was:" + msnContact.getOldStatus());
                if (MsnObject.TYPE_DISPLAY_PICTURE == msnContact.getAvatar().getType()) {
                    System.out.println("Resim Degisti:" + msnContact.getAvatar().getMsnObj());
                    messenger.retrieveDisplayPicture(msnContact.getAvatar(),
                                                     new DisplayPictureListener() {
                                                         public void notifyMsnObjectRetrieval(
                                                                                              MsnMessenger messenger,
                                                                                              DisplayPictureRetrieveWorker worker,
                                                                                              MsnObject msnObject,
                                                                                              ResultStatus result,
                                                                                              byte[] resultBytes,
                                                                                              Object context) {
                                                             // Log the result
                                                             //                                                             log.info("Finished Avatar retrieval "
                                                             //                                                                     + result);
                                                             // Process next contact
                                                             //retrieveNextContactAvatar(messenger);
       
                                                             // Check for the value
                                                             if (result == ResultStatus.GOOD) {
                                                                 // Create a new file to store the avatar
                                                                 File storeFile = new File("avatar"
                                                                         + System.currentTimeMillis()
                                                                         + ".png");
                                                                 System.out.println("File Path:"
                                                                         + storeFile.getAbsolutePath());
                                                                 try {
                                                                     FileOutputStream storeStream = new FileOutputStream(storeFile);
                                                                     storeStream.write(resultBytes);
                                                                     //goodAvatars.add(msnObject.getCreator());
                                                                     storeStream.close();
                                                                 } catch (FileNotFoundException e) {
                                                                     System.err.println("Critical error: Unable to find file we just created.");
                                                                 } catch (IOException e) {
                                                                     System.err.println("Critical error: Unable to write data to file system.");
                                                                 }
                                                             } else {
                                                                 //unavailableAvatars.add(msnObject.getCreator());
                                                             }
                                                         }
                                                     });
                }
                for (int j = 0; j < msnContact.getAvatar().getMsnObj().length; j++) {
                    System.out.println(msnContact.getAvatar().getMsnObj()[j]);
                }
                // TODO Auto-generated method stub
                super.contactStatusChanged(messenger, msnContact);
            }

By the way is it possible to change profile picture. Is following code works for this issue ?

DisplayPictureDuelManager displayPictureDuelManager = messenger.getDisplayPictureDuelManager();
displayPictureDuelManager.setDisplayPicutre(msnObject);
