• UIWebView/MPMoviePlayerController and the "Done" button

  - by David Sowsy

  I am using the UIWebView to load both streaming audio and video. I have properly set up the UIWebView delegate and I am receiving webViewDidStartLoading and webViewFinishedLoading events perfectly. The webview launches a full screen window (likely a MPMoviePlayerController) Apple's MoviePlayer example gets the array of Windows to determine which window the moviePlayerWindow is for adding custom drawing/getting at the GUI components. I believe this to be a bad practice/hack. My expectation is that I should be able to figure out when that button was clicked by either a delegate method or an NSNotification. It may also be the case that I have to poke around subviews or controllers with isKindOf calls, but I don't think those are correct approaches. Are my expectations incorrect, and if so, why? What is the correct way to bind an action to that "Done" button?

• Quaddratic Bezier Curve: Calculate Tangent

  - by stefan.at.wpf

  Hello, I have have a quadratic bezier curve and I want to calculate the slope of the tangent in a given point. For example, let it be the middlepoint of the quadratic bezier curve, therefore t=0.5 (please see the link below for a picture of this). I've calculated the first derivation of the formula for the quadratic bezier curve, however I get 400 as value for the slope, though it should be 0. Maybe I'm using the first derivation in a wrong way? I know I could also calculate the tangents using trigonometric functions, however I'd like to do it using the first derivation, shouldn't this be possible? Thanks for any hint! For clarification / please note: I'm interested in a general way to get the slope in a arbitrary given point on a quadratic bezier curve, not only to get the tangent in the start- and end point. A picture of my problem including the text above: http://cid-0432ee4cfe9c26a0.skydrive.live.com/self.aspx/%c3%96ffentlich/Quadratic%20Bezier%20Curve.pdf Thank you very much for any hint!

• Changing data in a django modelform

  - by Matt Hampel

  I get data in from POST and validate it via this standard snippet: entry_formset = EntryFormSet(request.POST, request.FILES, prefix='entries') if entry_formset.is_valid(): .... The EntryFormSet modelform overrides a foreign key field widget to present a text field. That way, the user can enter an existing key (suggested via an Ajax live search), or enter a new key, which will be seamlessly added. I use this try-except block to test if the object exists already, and if it doesn't, I add it. entity_name = request.POST['entries-0-entity'] try: entity = Entity.objects.get(name=entity_name) except Entity.DoesNotExist: entity = Entity(name=entity_name) entity.slug = slugify(entity.name) entity.save() However, I now need to get that entity back into the entry_formset. It thinks that entries-0-entity is a string (that's how it came in); how can I directly access that value of the entry_formset and get it to take the object reference instead?

• Spring MVC Web PetClinic Tutorial?

  - by wuntee

  Is there a tutorial that goes along with the PetClinic application? I have been trying to find one, but google is not helping me today. Specifically, I dont understand things like: @Autowired - what does that even mean? @RequestMapping(method = RequestMethod.GET) public String setupForm(@RequestParam("petId") int petId, ModelMap model) { Pet pet = this.clinic.loadPet(petId); model.addAttribute("pet", pet); return "petForm"; } How can a request return just a string? Shouldnt it need to return some sort of ModelAndView? Or does the application somehow redirect to whatever is returned? A lot of confusing concepts - if there is a tutorial, or video (like spring-security has) that would be very helpful. Thanks.

• YouTube player api - addEventListener() does not work for me?

  - by user246114

  Hi, I'm using the youtube player api. I'm following the doc here: http://code.google.com/apis/youtube/js_api_reference.html having a problem adding an event listener on the player, it seems to just get stuck there. I put an alert statement directly after, which never gets called: ytplayer.addEventListener("onStateChange", "onytplayerStateChange"); alert("I never get called..."); any idea why this would happen? Running it through FF chrome safari, same thing happens on all. Other player features all work fine. I'm using the swfobject version. I'm running this live from a server too. I don't get it. Thanks

• Blank Pages with Zen Cart v1.3.8 and PHP 5.3

  - by Michael Soriano

  I am trying to run a live Zen Cart store (version 1.3.8) on a my local machine which is PHP 5.3. I am aware of the incompatibilities between both versions and have dealt with it by applying the patch found here: http://www.zen-cart.com/forum/showthread.php?t=140960 I am able to login the admin side no problem, but when i navigate to the store - all i see are blank pages. How can I fix this issue? I'm hoping there is a fix elsewhere. Trying not to revert to an older PHP installation.

• In what programing language are the things i actualy care about writin? [closed]

  - by David

  To be more specific and less subjective: In what language are video games like Halo 3/COD 4/ mario cart written? Microsoft word for windows? for mac? The animation software used by big movie studios to make movies like toystory and monsters inc? The software that helps pilots control the F22 raptor? The software that watches the stock market? The software in the computer in my car? The software that makes the internet work? (this one is a bit vague, if more specificness is needed then google specifically) robots?

• Flex 4 Spark VideoDisplay in Popup causes memory leak

  - by Ben

  Hi, I'm currently building an air app with FB 4. I have a custom control that contains a VideoDisplay control, and which loaded using the PopupManager. Using the profiler, i've noticed that every time the my popup is loaded the memory for it gets allocated, but when it's closed the memory is never recovered. There's nothing else holding a reference to the popup. And if I don't set the source of the VideoDisplay object, then there is no leak - but as soon as the source is set I get a leak. I can't see any method to force close the stream or anything on the spark VideoDisplay control. Any idea or suggestions? EDIT: I have tried setting the source to null before closing the popup but that doesn't change anything. Also, I'm not holding any event listener to the video

• Communicating with the PC via USB connection in Android

  - by Danny Singh

  I'm fairly new to android programming and need some information for a 4th year forensics course project. Basically I am trying to create a suite of tools for live analysis of an android phone. I know how to get the information I need on the phone, but I was wondering if there was a way to communicate that information back to the PC? I want to be able to run a program from a PC, which, when the phone is docked, will allow the user to access information about the phone (ie currently running services/processes, bluetooth/wifi connections, etc). I have a bunch of methods that will run on the phone and get all the information, but I want to be able to call those methods from the PC, execute on the phone, then have the information sent back to the PC to display to the user instead of just displaying it on the phone. This is to leave as small a footprint on the phone as possible. Thanks a lot.

• Tokenizing Twitter Posts in Lucene

  - by Amaç Herdagdelen

  Hello, My question in a nutshell: Does anyone know of a TwitterAnalyzer or TwitterTokenizer for Lucene? More detailed version: I want to index a number of tweets in Lucene and keep the terms like @user or #hashtag intact. StandardTokenizer does not work because it discards the punctuation (but it does other useful stuff like keeping domain names, email addresses or recognizing acronyms). How can I have an analyzer which does everything StandardTokenizer does but does not touch terms like @user and #hashtag? My current solution is to preprocess the tweet text before feeding it into the analyzer and replace the characters by other alphanumeric strings. For example, String newText = newText.replaceAll("#", "hashtag"); newText = newText.replaceAll("@", "addresstag"); Unfortunately this method breaks legitimate email addresses but I can live with that. Does that approach make sense? Thanks in advance! Amaç

• Android RTSP coding problem

  - by NetApex

  I have Googled my butt off trying to find where if there is a surefire way to make rtsp work. I have a radio station that I listen to that streams via rtsp. Of course by default Android doesn't want to play it. If I pop the URL into yourmuze.fm and create a station there it lets me stream it to my phone. After checking how it works I come to find that it streams to the phone via rtsp! So obviously there is something amiss. What makes one stream work and one not? This is the stream I am attempting : rtsp://wms2.christiannetcast.com/yes-fm It is an audio stream so I would be thrilled with most peoples problem of "it only does audio and not video." When yourmuze.fm streams, DDMS states it brings up MovieView to play the audio if that helps at all.

• GC.AddMemoryPressure

  - by Steve Sheldon

  I am writing an application in C# that makes use of a 3rd party COM DLL, this dll creates a lot of resources (like bitmaps, video, data structures) in unmanaged memory. While digging around I came across the following call for the Garbage Collector: GC.AddMemoryPressure(long long bytesAllocated) It is documented in MSDN here: http://msdn.microsoft.com/en-us/library/system.gc.addmemorypressure.aspx This sounds like something I should be calling since this external dll is createing a lot of resources the CLR is unaware of. I guess I have two questions... How do I know how much memory pressure to add when the dll is 3rd party and it's not possible for me to know exactly how much memory this dll is allocating. How important is it to do this?

• How do I automate navigation to a website that requires authentication?

  - by Wiz

  Here's what I'm trying to achieve. I would like to write a script that will navigate to a website that requires me to be authenticated as myself, say Facebook, Live Spaces, Twitter or any other, and then have that script search for certain information on one of the pages of the website. I've done something similar in the past with the Windows.Forms WebBrowser control, which is a full blown implementation of IE that can be controlled through code and will store whatever cookies you get once you're authenticated, but it was very unfriendly to modify and I was hoping to use a scripting language instead, maybe Powershell or something of that sort. Are there maybe some good tutorials about this out there on the web? Thanks!

• ASP C# Web Developer default login, getting user ID session value

  - by m3n

  I've used the built-in wizard in Visual Web Developer 2008 to create a simple login system. I'd like to get hold of the logged in user's ID, but I'm not sure how. Peeking in the ASPNETDB.MDF in the table aspnet_Users, the column appears to be called "UserId". I gave it a go: Response.Write("ID: " + Session["UserId"]); but it's coming up blank. How do I do this? (This is not for a live project, no need to point out the sillyness in using the wizard.) Thanks

• emails not going out to all users

  - by user156814

  I have a few scripts that send out emails to my users, and for some reason not all users are getting the email. The site is not live yet, so its no big deal yet but I dont understand why. I have set up a few fake accounts, one with my school email, one with hotmail and one with yahoo. When I sign up with my school email I recieve the welcome email, but I get nothing with the other email accounts. The same thing with my 'forgot password' email. Only my school email works, yahoo and hotmail arent working... I'm running on a Linux server with Apache. Using PHP and the kohana framework 2.3.4 Thanks.

• Get the ID of the Current Textbox using JQuery

  - by Aaron Salazar

  I have a form with 3 text boxes that all do the same thing. They each call the JQuery function below after each keypress. Since I have 3 textboxes that all do the same thing, I'd like this function to work for all three. How do I change this function so that it'll grab the textbox's ID that is currently being edited instead of just the one? $(function() { $('#DocId').live('keydown', function() { var styleValue = $(this).val(); $('#tableContent').load( '/CurReport/TableResults', { style: styleValue } ); }) }); Thank you, Aaron

• Azure - Microsoft.IdentityModel not found

  - by Andy

  Hi There, I'm working with a WCF service in Azure, which uses Windows Live ID authentication with the recent deviceid requirements. When I host my WCF service locally in the compute emulator, it works properly, but when I deploy the cloud service to Azure and call it the same way (from another project that uses the WCF service as a service reference), I get the error: Could not load file or assembly 'Microsoft.IdentityModel, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The system cannot find the file specified. I found this post : http://social.msdn.microsoft.com/Forums/en-US/netservices/thread/cd139b5c-ad12-4298-af2f-1b2d0136a977 But there are a few problems: 1. I don't seem to have access to Microsoft.IdentityModel, only System.IdentityModel. I'm not sure why it's searching for something in 3.5 at all, as I'm building in .NET 4.0. 2. When I choose to "copy to local" on System.IdentityModel, it doesn't change anything. Any help? I would appreciate it! Best Regards, Andy

• Flash in firefox does not start unitl they show in page

  - by Leonardo

  I have this little problem. My client wanted two distinct swf on a web page: a viewer on top and a slideshow of images at bottom. Clicking a link on the slideshow make the viewer load a movie, by means of LocalConnection api. The slideshow has a default, so when the page is loaded a default movie start. This works nice on all browser. The only problem I have is on firefox. When screen resolution is too low, or the monitor is too small (netbook) the slideshow remain hidden until scrolling. Therefore at page loading it doesn't start and the main viewer don't get instructed on playing the default video. As soon as I scroll the page, and the slideshow swf display on page, it starts and everything works fine. Do you know if there are any solution to this ? I cannot change the design, I must have two distinct swf, they come from a library he has, and I am trying to reuse components. thanks Leonardo

• In LINQ-SQL, wrap the DataContext is an using statement - pros cons

  - by hIpPy

  Can someone pitch in their opinion about pros/cons between wrapping the DataContext in an using statement or not in LINQ-SQL in terms of factors as performance, memory usage, ease of coding, right thing to do etc. Update: In one particular application, I experienced that, without wrapping the DataContext in using block, the amount of memory usage kept on increasing as the live objects were not released for GC. As in, in below example, if I hold the reference to List of q object and access entities of q, I create an object graph that is not released for GC. DataContext with using using (DBDataContext db = new DBDataContext()) { var q = from x in db.Tables where x.Id == someId select x; return q.toList(); } DataContext without using and kept alive DBDataContext db = new DBDataContext() var q = from x in db.Tables where x.Id == someId select x; return q.toList(); Thanks.

• Account verification Yelp style, how is it more "secure" than traditional verification?

  - by Chad

  For business owners to "take control" of their business page on Yelp, they register for it. The Yelp system performs a telephone call-back. From watching to the video here, it sounds like a telephone version of what we all typically do - e-mail check. For e-mail check, it basically goes like this: User registers verify e-mail sent they click link inside verify e-mail site verifies Here's Yelp's: User registers verify screen shown with code Yelp calls user user enters code site verifies It's essentially the same thing, via phone. Is there any reason you can see why this method is better than the e-mail method?
