• Error connecting to Sonicwall L2TP VPN from iPad/iPhone

  - by db2

  A client has a Sonicwall Pro 2040 running SonicOS 3.0, and they'd like to be able to use the L2TP VPN client from their iPads to connect to internal services (Citrix, etc). I've enabled the L2TP VPN server on the Sonicwall, made sure to set AES-128 for phase 2, and set up the configuration on a test iPad with the appropriate username, password, and pre-shared key. When I attempt to connect, I get some rather cryptic error messages in the log on the Sonicwall: 2 03/29/2011 12:25:09.096 IKE Responder: IPSec proposal does not match (Phase 2) [My outbound IP address redacted] (admin) [WAN IP address redacted] 10.10.130.7/32 -> [WAN IP address redacted]/32 3 03/29/2011 12:25:09.096 IKE Responder: Received Quick Mode Request (Phase 2) [My outbound IP address redacted], 61364 (admin) [WAN IP address redacted], 500 4 03/29/2011 12:25:07.048 IKE Responder: IPSec proposal does not match (Phase 2) [My outbound IP address redacted] (admin) [WAN IP address redacted] 10.10.130.7/32 -> [WAN IP address redacted]/32 5 03/29/2011 12:25:07.048 IKE Responder: Received Quick Mode Request (Phase 2) [My outbound IP address redacted], 61364 (admin) [WAN IP address redacted], 500 The console log on the iPad looks like this: Mar 29 13:31:24 Daves-iPad racoon[519] <Info>: [519] INFO: ISAKMP-SA established 10.10.130.7[500]-[WAN IP address redacted][500] spi:5d705eb6c760d709:458fcdf80ee8acde Mar 29 13:31:24 Daves-iPad racoon[519] <Notice>: IPSec Phase1 established (Initiated by me).

• Cannot Send Item error in Outlook - permissions to registry?

  - by Tim Alexander

  The issue I am trying to solve is to do with users getting a Cannot Send Item error in Outlook 2007 connecting to Exchange 2007. Basically if there is an image in the email (either one they have pasted in or one from another email in the chain) they get a "Cannot Send Item" error. Initially thought it was a citrix issue but users get it when they RDP to a server as well. Changing the message to Rich Text works 80% of the time but I do not think this is a solution but more of a temporary workaround. After some troubleshooting we found that the error can be fixed by adding the user as a member of the local power users group. of course this is not really a fix. My thoughts were that the ability of a power user to add/remove software may give them more access to the registry which might allow them to get round a restriction that is in place for a normal user. I have tried going through a procmon but the wealth of information is confusing. It initially looked like it may be an Outlook 2007 email security setting but this does not change between power user and normal user (set to 1 in the registry, "Use the security setting from Outlook Security Settings Public Folders"). I am struggling to fine tune my troubleshooting to work out exactly what is blocking it. Has anyone had an experience with an error similar to this? Or are there any tips for trying to track down issues via procmon as I must admit my approach seems somewhat lacking :) EDIT: So I have trawled through the two logs we have from process monitor (one as a power user and one a normal user). annoyingly I can find no obvious difference where something is denied access. There are more access denied events in the normal user log but these are quickly followed by sucessful entries to the same path fractions of a second later. The only thing that does stand out is an access denied to HKCR.html. This does not even appear in the power user version of the log. From what I understand this helps determine the default browser which ties in nicely with the fact that 9 out of 10 times you can send the message as Rich Text. EDIT: Looks like KB2509470 was causing the issue. Not really sure why but when I can work out what it does and why it causes the problem will post here unless anyone beats me to it!

• IT merger - self-sufficient site with domain controller VS thin clients outpost with access to termi

  - by imagodei

  SITUATION: A larger company acquires a smaller one. IT infrastructure has to be merged. There are no immediate plans to change the current size or role of the smaller company - the offices and production remain. It has a Win 2003 SBS domain server, Win 2000 file server, linux server for SVN and internal Wikipedia, 2 or 3 production machines, LTO backup solution. The servers are approx. 5 years old. Cisco network equippment (switches, wireless, ASA). Mail solution is a hosted Exchange. There are approx. 35 desktops and laptops in the company. IT infrastructure unification: There are 2 IT merging proposals. 1.) Replacing old servers, installing Win Server 2008 domain controller, and setting up either subdomain or domain trust to a larger company. File server and other servers remain local and synchronization should be set up to a centralized location in larger company. Similary with the backup - it remains local and if needed it should be replicated to a centralized location. Licensing is managed by smaller company. 2.) All servers are moved to a centralized location in larger company. As many desktop machines as possible are replaced by thin clients. The actual machines are virtualized and hosted by Terminal server at the same central location. Citrix solutions will be used. Only router and site-2-site VPN connection remain at the smaller company. Backup internet line to insure near 100% availability is needed. Licensing is mainly managed by larger company. Only specialized software for PCs that will not be virtualized is managed by smaller company. I'd like to ask you to discuss both solutions a bit. In your opinion, which is better from the operational point of view? Which is more reliable, cheaper in the long run? Easier to manage from the system administrator's point of view? Easier on the budget and easier to maintain from IT department's point of view? Does anybody have any experience with the second option and how does it perform in production environment? Pros and cons of both? Your input will be of great significance to me. Thank you very much!

• Translating EventAggregators usage of SynchronizationContext to VB.Net

  - by Phil Sayers

  Working with a fairly large VB.Net back office winforms application. 1 million+ LOC. Big ball of mud, 90% of all code is in Forms & other UI controls. Slowly introducing better architecture as time & recources allows, We've been using ideas from the EventAggrgator by Jeremy Miller. http://codebetter.com/blogs/jeremy.miller/archive/2008/01/11/build-your-own-cab-extensible-pub-sub-event-aggregator-with-generics.aspx Initially I stripped out the usage of SynchronizationContext. Now I'm trying to introduce it back, and I'm struggling with the translation of the lamda stuff from c# to vb.net. Specifically this line of c# _context.Send(delegate { receiver.Handle(subject); }, null); This is the vb.net I have so far: _context.Send(New SendOrPostCallback(AddressOf listener.Handle(message)), Nothing) The error I'm getting is listener.Handle(message) <-- AddressOf operand must be the name of a method. I'm sure I'm missing something simple, but after staring at this for 2 days, I'm lost.

• Swift Mailer email sending problem

  - by air

  i have downloaded Swift Mailer from their website and try to send simple email with following code <?php require_once 'lib/swift_required.php'; $transport = Swift_SmtpTransport::newInstance('smtp.example.org', 25) ->setUsername('your username') ->setPassword('your password') ; $mailer = Swift_Mailer::newInstance($transport); //Create a message $message = Swift_Message::newInstance('Wonderful Subject') ->setFrom(array('[email protected]' => 'John Doe')) ->setTo(array('[email protected]', '[email protected]' => 'A name')) ->setBody('Here is the message itself') ; //Send the message $result = $mailer->send($message); ? once i run the page it gives error Warning: fsockopen() [function.fsockopen]: php_network_getaddresses: getaddrinfo failed: No such host is known. in E:\web_sites\swift_mail\lib\classes\Swift\Transport\StreamBuffer.php on line 233 Warning: fsockopen() [function.fsockopen]: unable to connect to smtp.fiveocean.net:25 (php_network_getaddresses: getaddrinfo failed: No such host is known. ) in E:\web_sites\swift_mail\lib\classes\Swift\Transport\StreamBuffer.php on line 233 Fatal error: Uncaught exception 'Swift_TransportException' with message 'Connection could not be established with host smtp.fiveocean.net [php_network_getaddresses: getaddrinfo failed: No such host is known. #0]' in E:\web_sites\swift_mail\lib\classes\Swift\Transport\StreamBuffer.php:235 Stack trace: #0 E:\web_sites\swift_mail\lib\classes\Swift\Transport\StreamBuffer.php(70): Swift_Transport_StreamBuffer->_establishSocketConnection() #1 E:\web_sites\swift_mail\lib\classes\Swift\Transport\AbstractSmtpTransport.php(101): Swift_Transport_StreamBuffer->initialize(Array) #2 E:\web_sites\swift_mail\lib\classes\Swift\Mailer.php(74): Swift_Transport_AbstractSmtpTransport->start() #3 E:\web_sites\swift_mail\test.php(33): Swift_Mailer->send(Object(Swift_Message)) #4 {main} thrown in E:\web_sites\swift_mail\lib\classes\Swift\Transport\StreamBuffer.php on line 235 if i remove the line $result = $mailer->send($message); then page execute and no error message display, as soon as i add above line to send email, i got error. my outgoing server, port and user id & passwords are correct in my file.

• android pending intent notification problem

  - by spagi

  Hi all! I have a alarm thing going on in my app and it launches a notification that then when pressed launched an activity. The problem is that when I create more than one alarm then the activity launched from the notification gets the same extras as the first one. I think the problem is either with the intent i put in the pending intent or in the pending intent itself. I think I might need to put a flag on one of these but I dont know which one. Intent showIntent =new Intent(context, notificationreceiver.class); showIntent.putExtra("details", alarmname); PendingIntent contentIntent = PendingIntent.getActivity(context, 0, showIntent, 0); notification.setLatestEventInfo(context, "The event is imminent", alarmname, contentIntent); And the receiver of the notification Bundle b = getIntent().getExtras(); String eventname = b.getString("details"); details.setText(eventname); The "details" extra is the same to every the next time a notification happens instead of having the different value. Until I set the intents I am sure that the correct value goes to the "details" so its a problem of getting the first intent everytime i press any notification. How can I make it to launch the correct intents? Hope I was as clear as i could Thanks!

• Feature element repeatedly added with every feature activation/deactivation

  - by ccomet

  This is a very minor behavior when compared with the entire scope, but it is one that I'd like to put a stop to. I have created a very, very simple SharePoint Feature. It has two elements in its manifest: an aspx webpart page, and an elements xml. I'll paraphrase my elements xml, which just adds a module, below. <Elements xmlns="http://schemas.microsoft.com/sharepoint/"> <Module Name="Pass" Url="" Path=""> <File Url="pasq.aspx" NavBarHome="True" Type="Ghostable"> <AllUsersWebPart WebPartZoneID="Left" WebPartOrder="0"> <![CDATA[ WARGH THIS PART DOESN'T MATTER FOR THIS QUESTION! ]]> </AllUsersWebPart> </File> </Module> </Elements> Now, on the first time I deploy and activate this feature, it works properly. But if I have to deactivate and then reactivate the feature in order to fix some properties in the webpart, then I find myself with a second webpart on the page. Naturally, each similar cycle will just add more and more. I understand that a new webpart must be created in order to employ the changes I just made, but why is the old webpart still on the page? Can I make this older webpart go away automatically as part of the feature activation/deactivation process without needing to employ a Receiver class?

• establishing a socket connection from iPhone to MAC/PC

  - by user319572

  Hello, I just started getting into XCode and Co. What I am trying is to send accelerometer data via WLAN to a PC or MAC over a Socket connection. I am trying at the moment with the iPhone simulator, on the other site a netbook with a JAVA program shall receive a test string for starters. Unfortunately my socket will not initialize. What am I doing wrong? NSString *recStr = @"192.168.0.5"; //String with receiver IP NSHost *hoster = [NSHost hostWithName:recStr]; //create a host NSOutputStream *sendData; //create an output stream [NSStream getStreamsToHost:hoster port:8000 inputStream:nil outputStream:&sendData]; [sendData retain]; [sendData setDelegate:self]; [sendData open]; A warning says NSStream may not respond to '+getStreamsToHost:inputSream:outputStream:' So I guess parameters are wrong. But why and how to do it right? The program starts but I don't think I can send anything as long as this warning shows up (have not tried though). Thank you in advance, Andreas

• Developing a GPS car tracking system in C#

  - by Click Ok

  I'm in the brainstorming phase to develop a GPS car tracking system requested by a customer. I myself know the directions to build some GPS system to mobile phones and etc. But sincerely I don't know how to start in that project. That is the scenario: 1) The cars will get a device with a SIM CARD that will emit GPS signals. 2) My customer will in any place (home, work, etc) with a web connection will see in the map where the car is located. For me, I have not problems at get the GPS data, convert to usable info and show the position in some map system (like Google Maps or MS Bing Maps, by example). My problem is, how I do to retrieve that "GPS Signal" from device in the car? I will need some kind of "Receiver Device" connected to a web server machine in order to my application to consume that data? Or "automagically" my sodtware will receive the info from a third-party web-service? Or what? I thank for any help!

• PHP doesn't properly URL-decode POST values, or is the bug somewhere else?

  - by Vilx-

  I have a PHP website that integrates with PayPal. As part of it's normal operation it sends a POST request to a user defined URL about every transaction (and some other events). It's called IPN for those who know. All was/is working just fine, until we moved to a new hosting provider last week. This naturally resulted in downtime, changing DNS entries, PHP misconfigurations, etc. In short - PayPal was unable to send the notifications for a few days. Now, this is not that bad, because there is an option just for that - you can log into PayPal, go to the appropriate menu item, and have it resend the failed notifications. Which we did, and it resulted in over 400 error emails. The problem is that normally the email of the receiver ($_POST['business']) is received by PHP as [email protected], but when resending it comes out as my%40business.com. And the request validation goes crazy. Obviously either something somewhere is missing a call to urldecode() or something is doing one too many urlencode(). But who? Is this a bug in PHP? I've never had such a problem before, not with any POST data ever. Perhaps PayPal has a bug? Wouldn't be surprising, but then this should have been caught ages ago. Or perhaps I'm doing something wrong and I should really be calling the urldecode() myself?

• BroadcastReceiver not receiving an alarm's broadcast

  - by juanjux

  I have a code that sets a new repeating alarm (on production I'll use a inexactRepeating), but the BroadCastReceiver I've registered for handling it is not being called. Here is the code where I set the alarm: newAlarmPeriod = 5000; // For debugging Intent alarmIntent = new Intent(this, GroupsCheckAlarmReceiver.class); PendingIntent sender = PendingIntent.getBroadcast(this, Constants.CHECK_ALARM_CODE, alarmIntent, 0); AlarmManager am = (AlarmManager) getSystemService(ALARM_SERVICE); am.setRepeating(AlarmManager.RTC_WAKEUP, System.currentTimeMillis() + newAlarmPeriod, newAlarmPeriod, sender); It seems to work and it triggers and alarm every five seconds, as seen in the output of "adb shell dumpsys alarm": DUMP OF SERVICE alarm: Current Alarm Manager state: Realtime wakeup (now=1269941046923): RTC_WAKEUP #1: Alarm{43cbac58 type 0 android} type=0 when=1269997200000 repeatInterval=0 count=0 operation=PendingIntent{43bb1738: PendingIntentRecord{43bb1248 android broadcastIntent}} RTC_WAKEUP #0: Alarm{43ce30e0 type 0 com.almarsoft.GroundhogReader} type=0 when=1269941049555 repeatInterval=5000 count=1 operation=PendingIntent{43d990c8: PendingIntentRecord{43d49108 com.almarsoft.GroundhogReader broadcastIntent}} RTC #1: Alarm{43bfc250 type 1 android} type=1 when=1269993600000 repeatInterval=0 count=0 operation=PendingIntent{43c5a618: PendingIntentRecord{43c4f048 android broadcastIntent}} RTC #0: Alarm{43d67dd8 type 1 android} type=1 when=1269941100000 repeatInterval=0 count=0 operation=PendingIntent{43c4e0f0: PendingIntentRecord{43c4f6c8 android broadcastIntent}} Broadcast ref count: 0 Alarm Stats: android 24390ms running, 0 wakeups 80 alarms: act=android.intent.action.TIME_TICK flg=0x40000004 com.almarsoft.GroundhogReader 26ms running, 2 wakeups 2 alarms: flg=0x4 cmp=com.almarsoft.GroundhogReader/.GroupsCheckAlarmReceiver But for some reason my BroadCastReceiver is not being called when the alarm is triggered. I've declared it on the Manifest: <receiver android:name=".GroupsCheckAlarmReceiver" /> And this is the abbreviated code: public class GroupsCheckAlarmReceiver extends BroadcastReceiver{ @Override public void onReceive(Context context, Intent intent) { Toast.makeText(context, "XXX Alarm worked.", Toast.LENGTH_LONG).show(); Log.d("XXX", "GroupsCheckAlarmReceiver.onReceive"); }

• Having Uploadify e-mail a link to download the file

  - by kwek-kwek

  Uploadify is a jQuery plugin that allows the easy integration of a multiple (or single) file uploads on your website. It requires Flash and any backend development language. An array of options allow for full customization for advanced users, but basic implementation is so easy that even coding novices can do it. I wanted to ask if It is possible to sends out a link of a file that has just been uploaded wioth the e-mail notification of Uploadify. Here is the code for uploadify.php : <?php if (!empty($_FILES)) { $tempFile = $_FILES['Filedata']['tmp_name']; $targetPath = $_SERVER['DOCUMENT_ROOT'] . $_REQUEST['folder'] . '/'; $targetFile = str_replace('//','/',$targetPath) . $_FILES['Filedata']['name']; // $fileTypes = str_replace('*.','',$_REQUEST['fileext']); // $fileTypes = str_replace(';','|',$fileTypes); // $typesArray = split('\|',$fileTypes); // $fileParts = pathinfo($_FILES['Filedata']['name']); // if (in_array($fileParts['extension'],$typesArray)) { // Uncomment the following line if you want to make the directory if it doesn't exist // mkdir(str_replace('//','/',$targetPath), 0755, true); move_uploaded_file($tempFile,$targetFile); echo "1"; // } else { // echo 'Invalid file type.'; // } } //define the receiver of the email $to = '[email protected]'; //define the subject of the email $subject = 'Test email'; //define the message to be sent. Each line should be separated with \n $message = "Hello World!\n\nThis is my first mail."; //define the headers we want passed. Note that they are separated with \r\n $headers = "From: [email protected]\r\nReply-To: [email protected]"; //send the email $mail_sent = @mail( $to, $subject, $message, $headers ); //if the message is sent successfully print "Mail sent". Otherwise print "Mail failed" echo $mail_sent ? "Mail sent" : "Mail failed"; ?>

• VLC desktop streaming

  - by StackedCrooked

  Edit I stopped using VLC and switched to GMax FLV Encoder. It does a much better job IMO. Original post I am sending my desktop (screen) as an H264 video stream to another machine that saves it to a file using the follwoing command lines: Sender of the stream: vlc -I dummy --sout='#transcode{vcodec=h264,vb=512,scale=0.5} :rtp{mux=ts,dst=192.168.0.1,port=4444}' Receiver of the stream: vlc -I rc rtp://@:4444 --sout='#std{access=file,mux=ps,dst=/home/user/output.mp4}' --ipv4 This works, but there are a few issues: The file is not playable with most players. VLC is able to playback the file but with some weirdness: = it takes about 10 seconds before the playback actually begins. = seeking doesn't work. Can someone point me in the right direction on how to fix these issues? EDIT: I made a little progress. The initial delay in playback is because the player is waiting for a keyframe. By forcing the sender of the stream to create a new key-frame every 4 seconds I could decrease the delay: :screen-fps=10 --sout='#transcode{vcodec=h264,venc=x264{keyint=40},vb=512,scale=0.5} :rtp{mux=ts,dst=192.168.0.1,port=4444}' The seeking problem is not solved however, but I understand it a little better. The RTP stream is saved as a file in its original streaming format, which is normally not playable as a regular video file. VLC manages to play this file, but most other players don't. So I need to convert it to a regular video file. I am currently investigating whether I can do this with ffmpeg if I provide it with an SDP file for the recorded stream. All help is welcome!

• Send a public broadcast from an AppWidget in Android

  - by greve

  I have a widget for a music player and want to be able to send broadcasts when pushing the different buttons. What I want to do is when a button is pushed, the widget sends a public broadcast to another BroadcastReceiver so it can handle the different actions. In my activity class with the BroadcastReceiver: private BroadcastReceiver broadcastReceiver = new BroadcastReceiver() { @Override public void onReceive(Context context, Intent intent) { String action = intent.getAction(); if (action.equals(Constants.ACTION_NEXT)) { Log.d("RECEIVER", "ACTION_NEXT"); } } }; @Override protected void onStart() { super.onStart(); IntentFilter filter = new IntentFilter(); //Widget actions filter.addAction(Constants.ACTION_NEXT); registerReceiver(broadcastReceiver, new IntentFilter(filter)); } In my Widget: public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds) { RemoteViews views = new RemoteViews(context.getPackageName(), R.layout.widget); PendingIntent pendingIntent = PendingIntent.getBroadcast(context, 0, new Intent(Constants.ACTION_NEXT), 0); views.setOnClickPendingIntent(R.id.WidgetNextButton, pendingIntent); appWidgetManager.updateAppWidget(appWidgetId, views); } Any help or other solutions are very much appreciated!

• Broadcasting an intent to a specific component.

  - by Nic Strong

  I have an activity that is starting a background operation in another service. This activity receives various notifications from this service. As part of the intent I use to initiate the background operation I pass extra data with the context of my activity so the background service can broadcast intents back to me (the download service is a good example of this usage). So in the activity I use the following to attach the context: intent.putExtra(Intents.EXTRA_NOTIFICATION_PACKAGE, IntentTestActivity.this.getPackageName()); intent.putExtra(Intents.EXTRA_NOTIFICATION_CLASS, IntentTestActivity.class.getCanonicalName()); intent.putExtra(Intents.EXTRA_NOTIFICATION_EXTRAS, myContext); I register for the notifications in the activity: IntentFilter intentFilter = new IntentFilter(); intentFilter.addAction(Intents.ACTION_NOTIFICATION); intentFilter.addCategory(Intents.CATEGORY_COMPLETION); intentFilter.addCategory(Intents.CATEGORY_PROGRESSS); Intent intent = registerReceiver(receiver, intentFilter); In the background service I send notifications with the following code: void broadcastNotification(String action, String category, String packageName, String className, String extras, int operationResult) { Intent intent = new Intent(action); intent.addCategory(category); intent.setClassName(packageName, className); if (extras != null) { intent.putExtra(Intents.EXTRA_NOTIFICATION_EXTRAS, extras); } intent.putExtra(Intents.EXTRA_OPERATION_RESULT, operationResult); context.sendBroadcast(intent); } My problem is that the above broadcast will never be received. If however I comment out the line intent.setClassName(packageName, className); Then the broadcast is received. Is it a problem with my filter? Do I have to specify intents intended for a specific component? Or cannot I not use such fine grain control over the delivery of broadcasts. Thanks, Nic

• Can a function return an object? Objective-C and NSMutableArray

  - by seaworthy

  I have an NSMutableArray. It's members eventually become members of an array instance in a class. I want to put the instantiantion of NSMutable into a function and to return an array object. If I can do this, I can make some of my code easier to read. Is this possible? Here is what I am trying to figure out. //Definition: > function Objects (float a, float b) { > NSMutableArray *array = [[NSMutableArray alloc] init]; > [array addObject:[NSNumber numberWithFloat:a]]; > [array addObject:[NSNumber numberWithFloat:b]]; > //[release array]; ???????? return array; > } //Declaration: Math *operator = [[Math alloc] init]; [operator findSum:Objects(20.0,30.0)]; My code compiles if I instantiate NSMutableArray right before I send the message to the receiver. I know I can have an array argument along with the method. What I have problem seeing is how to use a function and to replace the argument with a function call. Any help is appreciated. I am interested in the concept not in suggestions to replace the findSum method.

• Social Network News Feed Database & Design

  - by pws5068

  I'm designing a News Feed system using PHP/MySQL similar to facebook's. I have asked a similar question before but now I've changed the design and I'm looking for feedback. Example Notifications: User_A commented on User_B's new album. "Hey man nice picture!" User_B added a new Photo to [his/her] profile. [show photo thumbnail] Initially, I implemented this using excessive columns for Obj1:Type1 | Obj2:Type2 | etc.. Now the design is set up using a couple special keywords, and actor/receiver relationships. My database is designed for efficiency - using a table of messages joined on a table containing userid,actionid,receiverid,receiverObjectTypeID, Here's a condensed version of what it will look like once joined: News_ID | User_ID | Message | Timestamp 2643 A %a commented on %o's new %r. SomeTimestamp 2644 B %a added a new %r to [his/her] profile. SomeTimestamp %a = the User_ID of the person doing the action %r = the receiving object %o = the owner of the receiving object (for example the owner of the album) (NULL if %r is a user) Questions: Is this a smart (efficient/scalable) way to move forward? How can I show messages like: "User_B added 4 new photos to his profile."?

• Getting nice sound from Java

  - by Peter Lang

  I managed to play midi files using Java, but it produces some distracting noise. I figured out that this is caused by the poor quality soundbank file shipped with Java 6 SDK/JRE. How can I improve that quality? Here is what I have so far: MidiNote example using a Receiver works fine (sounds the same as when playing midi files with other players), so it does not seem to use the Soundbank shipped with Java but the fallback mechanism that uses a hardware MIDI port. Using SimpleMidiPlayer example to play a Midi file works, but the quality is poor. When I delete lib/audio/soundbank.gm, the quality is not bad any more, so the fallback is used again. When I put soundbank-deluxe.gm into the same directory, it is used and produces much better sound. Messing with the clients soundbank file as described in the official Installation Instructions certainly isn't an option, so I tried to put the new soundbank-file into the jar-file and load it: Soundbank soundbank = MidiSystem.getSoundbank( getClass().getResourceAsStream("soundbank-deluxe.gm")); if(synthesizer.isSoundbankSupported(soundbank)) { System.out.println(synthesizer.loadAllInstruments(soundbank)); } This prints true, but the sound remains unchanged. What am I doing wrong loading the soundbank file? Can I force the hardware MIDI port to be used instead of the standard soundbank file?

• NSMutableDictionary with UIButton* as keys - iPhone development

  - by Alejandro A.

  Hi, I'm new to iPhone development and I have a question that may have a very simple answer. I am trying to add buttons to a view and these buttons are associated with a custom class that I defined. When I add the buttons to the view, I would like to know what class these buttons correspond to. This is because when I press the button, I need to get some information about the class, but the receiver of the message is another class. I couldn't find information about an error that I'm getting on the web. The problem I have is that I'm trying to create an NSMutableDictionary where the keys are of type UIButton* and the values are of my custom type: // create button for unit UIButton* unitButton = [[UIButton alloc] init]; [sourceButtonMap setObject:composite forKey:unitButton]; Of course, the sourceButtonMap is defined in the class and initialized in the init function as sourceButtonMap = [[NSMutableDictionary alloc] init]; The error I get when I try to add the key-value pair is: *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '*** -[UIButton copyWithZone:]: unrecognized selector sent to instance 0x3931e90' Is this happening because I can't store UIButton* as keys? Can anyone point me why I'm getting this error? Thank you all, aa

• Android - sendOrderedBroadcast help

  - by Donal Rafferty

  I am trying to use a sendOrderedBroadcast in my Android app. I want to be able to send the Intent from one of my applications to another and I then want to get data back from the Application that recieves the Intent, in this case a boolean true or false. Here is the current code: Intent i = new Intent(); i.setAction(GlobalData.PROPOSE_IN_DOMAIN_ROAM_INTENT); i.putExtra("com.testnetworks.QCLEVEL", aProposedTheoreticalQoSLevel); sendOrderedBroadcast(i, null, null, null, Activity.RESULT_OK, null, null); Is this the correct way to achieve what I want? If so what do I use as the resultReceiver* parameter? (3rd parameter) And then how to I recieve data back from the Broadcast? I have done a quick google and not come up with any examples, any help or examples greatly appreciated. UPDATED CODE: sendOrderedBroadcast(i, null, domainBroadcast, null, Activity.RESULT_OK, null, null); class DomainBroadcast extends BroadcastReceiver{ @Override public void onReceive(Context arg0, Intent intent) { String action = intent.getAction(); if(GlobalData.PROPOSE_IN_DOMAIN_ROAM_INTENT.equals(action)){ Log.d("BROADCAST", "Returning broadcast"); Bundle b = intent.getExtras(); Log.d("BROADCAST", "Returning broadcast " + b.getInt("com.testnetworks.INT_TEST")); } } @Override public void onReceive(Context context, Intent intent) { String action = intent.getAction(); if(GlobalData.PROPOSE_IN_DOMAIN_ROAM_INTENT.equals(action)){ Bundle b = intent.getExtras(); int testQCLevel = b.getInt("com.testnetworks.QCLEVEL"); switch(testQCLevel){ case 1: Log.d("QCLevel ", "QCLevel = UNAVAILABLE"); break; case 2: Log.d("QCLevel ", "QCLevel = BELOWUSABILITY"); break; case 3: Log.d("QCLevel ", "QCLevel = VOICE"); break; } intent.putExtra("com.testnetworks.INT_TEST", 100); } So according to the Doc's I should recieve 100 back in my DomainBroadcast reciever but it always comes back as 0. Can anyone see why? *resultReceiver - Your own BroadcastReceiver to treat as the final receiver of the broadcast.

• [android] Is it possible to receive SMS message on appWidget?

  - by cappuccino

  [Android] Hi, everyone. Is it possible to receive SMS message on appWidget? I saw android sample soucrce(API Demos). In API Demos, ExampleAppWidgetProvider class extends AppWidgetProvider, not Activity. So, I guess it is impossible to regist SMS Receiver like this, rcvIncoming = new BroadcastReceiver() { @Override public void onReceive(Context context, Intent intent) { Log.i("telephony", "SMS received"); Bundle data = intent.getExtras(); if (data != null) { // SMS uses a data format known as a PDU Object pdus[] = (Object[]) data.get("pdus"); String message = "New message:\n"; String sender = null; for (Object pdu : pdus) { SmsMessage part = SmsMessage.createFromPdu((byte[])pdu); message += part.getDisplayMessageBody(); if (sender == null) { sender = part.getDisplayOriginatingAddress(); } } Log.i(sender, message); } } }; registerReceiver(rcvIncoming, new IntentFilter("android.provider.Telephony.SMS_RECEIVED")); My goal is to receive SMS message on my custom appWidget. any help would be appreciated!!

• PHP News Feed Database & Design

  - by pws5068

  I'm designing a News Feed system using PHP/MySQL similar to facebook's. I have asked a similar question before but now I've changed the design and I'm looking for feedback. Example News: User_A commented on User_B's new album. "Hey man nice pictures!" User_B added a new Photo to [his/her] profile. [show photo thumbnail] Initially, I implemented this using excessive columns for Obj1:Type1 | Obj2:Type2 | etc.. Now the design is set up using a couple special keywords, and actor/receiver relationships. My database uses a table of messages joined on a table containing userid,actionid,receiverid,receiverObjectTypeID, Here's a condensed version of what it will look like once joined: News_ID | User_ID | Message | Timestamp 2643 A %a commented on %o's new %r. SomeTimestamp 2644 B %a added a new %r to [his/her] profile. SomeTimestamp %a = the User_ID of the person doing the action %r = the receiving object %o = the owner of the receiving object (for example the owner of the album) (NULL if %r is a user) Questions: Is this a smart (efficient/scalable) way to move forward? How can I show messages like: "User_B added 4 new photos to his profile."?

• Simple continuously running XMPP client in python

  - by tom

  I'm using python-xmpp to send jabber messages. Everything works fine except that every time I want to send messages (every 15 minutes) I need to reconnect to the jabber server, and in the meantime the sending client is offline and cannot receive messages. So I want to write a really simple, indefinitely running xmpp client, that is online the whole time and can send (and receive) messages when required. My trivial (non-working) approach: import time import xmpp class Jabber(object): def __init__(self): server = 'example.com' username = 'bot' passwd = 'password' self.client = xmpp.Client(server) self.client.connect(server=(server, 5222)) self.client.auth(username, passwd, 'bot') self.client.sendInitPresence() self.sleep() def sleep(self): self.awake = False delay = 1 while not self.awake: time.sleep(delay) def wake(self): self.awake = True def auth(self, jid): self.client.getRoster().Authorize(jid) self.sleep() def send(self, jid, msg): message = xmpp.Message(jid, msg) message.setAttr('type', 'chat') self.client.send(message) self.sleep() if __name__ == '__main__': j = Jabber() time.sleep(3) j.wake() j.send('[email protected]', 'hello world') time.sleep(30) The problem here seems to be that I cannot wake it up. My best guess is that I need some kind of concurrency. Is that true, and if so how would I best go about that? EDIT: After looking into all the options concerning concurrency, I decided to go with twisted and wokkel. If I could, I would delete this post.
