• How to know when the MPMoviePlayerController has been paused in iPhone?

  - by iPhoney

  I want to add an overlay view for my video when the video is paused by the user. Is there any way to get the pause notification from MPMoviePlayerController? According to Apple Doc, there should be ways to do this but I can't find which notification should I use for this purpose. Quote: In addition to being notified when playback finishes, interested clients can be notified in the following situations: -When the movie player begins playing, is paused, or begins seeking forward ... For more information, see the Notifications section in this reference.

• Widget starting a service also starts main activity

  - by Nick

  Hi, I have a widget that is supposed to start and stop a service (start it when it's not running, stop it when it is). This is working fine, however, each time the service is started, my app's main activity is also launched, which I don't want. If I remove the MAIN-intent-filter ( <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" />) from the app's manifest, it works as I want it to (without launching the main-activity, just the service), but then I obviously don't have a main activity anymore... This is how I start the service (I would assume this is the normal way, and I can't see any reference to what might cause the MAIN intent to fire): Intent svc = new Intent(this, OnOffService.class); startService(svc); Thanks, Nick

• Up to date Ruby On Rails books?

  - by Earlz

  Hello, I've been trying to learn Rails for a while now and I just can not piece it all together with random blogs and SO questions, so I've decided I need a full book/ebook. Can anyone suggest a good one? I've been looking at Agile Web Development With Rails 4th edition. There is an old question about Ruby On Rails books but it is from 2008 and there has been new Rails releases since then. I basically would like a book that is more than a reference, but also doesn't assume I'm a non-programmer. Also, I already know a lot of Ruby. So, what books would you recommend that is up to date and also doesn't treat me like a baby?

• How to create a reusable form using COCOA bindings.

  - by Juliano Sott

  hi. I want to make a user interface in which the user can edit two objects at the same time. The main window would have a vertical split view and a form on each side of the view. The problem is that the two forms are identical and I don't want to duplicate the view components in the interface builder. I want to create the form one time and add a reference to it in each side of the split view, each one using a different object source. I could use a NSForm, but the form is not a simple grid of outputTexts and inputText. They have a master table, and diverse kinds of inputs types, like combos, in the detail. How do I create the reusable form using the interface builder? Or how can I do it programmatically? Do I have to create a subclass of NSView and add the individual components in the code? Thanks, Juliano

• MySQL: 4 Table "has-many-through" Join?

  - by Nebs

  Let's say I have the following 4 tables (for examples' sake): Owners, Trucks, Boxes, Apples. An owner can have many trucks, a truck can have many boxes and a box can have many apples. Owners have an id. Trucks have an id and owner_id. Boxes have an id and truck_id. Apples have an id and box_id. Let's say I want to get all the apples "owned" by an owner with id = 34. So I want to get all the boxes that are in boxes that are in trucks that owner 34 owns. There is a "hierarchy" if you will of 4 tables that each only has reference to its direct "parent". How can I quickly filter boxes while satisfying conditions across the other 3 tables? I hope that made sense somewhat. Thanks.

• EntityFramework gives IDisposable error

  - by Snoop Dogg

  I use EF for the back-end DataLayer in my asp.net websites. I create a class library and add the Model in it, reference it and use it from the ASP.NET Website. But this time, I generated the model from database but it seems does not implement IDisposable, and the methods I used to see are not there. DeleteObject , SaveChanges etc. There are only Two tables in the DB and the Model was generated with only the TableSets and two methods AddToTableSet ... Had anybody encountered such a problem?

• C++ - defining static const integer members in class definition

  - by HighCommander4

  My understanding is that C++ allows static const members to be defined inside a class so long as it's an integer type. Why, then, does the following code give me a linker error? #include <algorithm> #include <iostream> class test { public: static const int N = 10; }; int main() { std::cout << test::N << "\n"; std::min(9, test::N); } The error I get is: test.cpp:(.text+0x130): undefined reference to `test::N' collect2: ld returned 1 exit status Interestingly, if I comment out the call to std::min, the code compiles and links just fine (even though test::N is also referenced on the previous line). Any idea as to what's going on? My compiler is gcc 4.4 on Linux.

• javascript window.close, once again

  - by John Kjøller

  Im sorry if I havent done my research properly, - but couldnt find the answer I needed, so here goes: From my main page I open a new window using mainPlayer = window.open(); This window stays open until user clicks on a mainPlayer.close(); event. (or simply x closes the window) However, the idea is to make it possible to let the player keep playing, while browsing around the rest of the pages. But as soon as the user leaves the page that opened the mainPlayer window, the reference to the mainPlayer window seem to be lost. How do I, from the site's other pages, check if the mainPlayer window is open and close it on a click event? Thx John

• What is the '^' in Objective-C

  - by Chris Paterson

  What does the '^' mean in the code below? @implementation AppController - (IBAction) loadComposition:(id)sender { void (^handler)(NSInteger); NSOpenPanel *panel = [NSOpenPanel openPanel]; [panel setAllowedFileTypes:[NSArray arrayWithObjects: @"qtz", nil]]; handler = ^(NSInteger result) { if (result == NSFileHandlingPanelOKButton) { NSString *filePath = [[[panel URLs] objectAtIndex:0] path]; if (![qcView loadCompositionFromFile:filePath]) { NSLog(@"Could not load composition"); } } }; [panel beginSheetModalForWindow:qcWindow completionHandler:handler]; } @end === I've searched and searched - is it some sort of particular reference to memory?

• WCF - call same service from client and server side

  - by Steve

  I have a simple WCF service that I call server side from code behind via a service reference. It's used for validation and works and was automatically setup by Visual Studio and is using SOAP I think because the binding is wsHttpBinding. I want to use the same WCF service, but call it client side from jQuery using ajax(). I'm trying to implement it by way of these instructions. But if I make the changes to get the client side call working, I have to add the decoration below which I think will break what works on the server side and also change the system.serviceModel section in web.config. [WebInvoke(Method = "POST", BodyStyle = WebMessageBodyStyle.Wrapped, ResponseFormat = WebMessageFormat.Json, RequestFormat= WebMessageFormat.Json) ] How do I have a WCF service that can be called both from the server-side and client side (jQuery/ajax)?

• DependencyProperty Orientation problem

• iphone app hangs in AppDelegate (?)

  - by d_CFO

  No nib/IB, so I've inserted "myAppDelegate" in main and deleted the reference to main.xib in info.plist. Debug continues nicely through all five tab controllers; they seem to have gotten properly loaded into the nav controller. In fact, control passes out of the last "}" in applicationDidFinishLaunching. But there was no (visible) response back at [window addSubview:[tabBarController view]]; and [window makeKeyAndVisible]; statements, much less to the loadView within the first tab (program execution never gets there). The last line is, UIApplication _performInitializationWithURL:sourceBundleID:]. I missed a step? I executed a step improperly?

• What's a good way to throw and handle events in PHP?

  - by techexpert

  Hi everyone, I am just trying to get a general idea about the event prcessing mechanism in PHP5 in as neat way as possible. First of all I understand that a PHP application is not exactly a persistent type, so the events may not make a lot of sense, but from the OO perspective it might be a very elegant way to "communicate" between the objects. So I am thinking that it would make sense to separate the events on the external events, such as $_POST & $_GET and the internal ones, i.e. function callbacks. As far as the external ones, is it a good idea to process the $_GETs and $_POSTs directly, or is it better to wrap them into an event of some sort? Also, in order to process the internal events, do you have to pass the reference to the event handler/dispatcher to each class so they know how to throw them? I was thinking to use the PEAR EventDispatcher to do the work, but I am open to other suggestions. Thank you!

• Getting the hang of CodeIgniter - Templating / loading views

  - by kilrizzy

  Attempting to learn CI and going through the docs to get a better understanding. Without getting a separate library, I could make a template by including a list of views like so: $this->load->view('header'); $this->load->view('navigation'); $this->load->view('sidenav_open'); $this->load->view('blocks/userinfo'); $this->load->view('blocks/stats'); $this->load->view('sidenav_close'); $this->load->view('content',$data); $this->load->view('footer'); This makes sense but would I actually have that on each of my controllers (pages)? Not sure if there is a way to include this in the initial controller (welcome) and then in the others somehow reference it? Or perhaps there is something I am missing completely

• Javascript code in ASP.NET MVC Partial Views (ASCX) or not?

  - by Alex

  Is there a "best practice" for placing Javascript code when you have many partial views and JS code that's specific to them? I feel like I'm creating a maintenance nightmare by having many partial views and then a bunch of independent Javascript files for them which need to be synced up when there is a partial view change. It appears, for maintenance purposes, better to me to put the JS code with the partial view. But then I'm violating generally accepted practices that all JS code should be at the bottom of the page and not mixed in, and also I'd end up with multiple references to the same JS file (as I'd include a reference in each ASCX for intellisense purposes). Does anyone have a better idea? Thank you!

• Call AppDelegate Method from Class

  - by golfromeo

  Basically, I need to call a method in my AppDelegate from one of my view controller classes. Currently, I'm doing the following: myAppDelegate *appDelegate = (myAppDelegate *)[[UIApplication sharedApplication] delegate]; [appDelegate doMethod]; And including the myAppDelegate.h at the top of the .m file of the class: #import "myAppDelegate.h" When I run it, everything works... But I get the following warning: warning 'myAppDelegate' may not respond to '-doMethod' Is there another way that I should reference the app delegate? Thanks for any help in advance.

• Variable function name Javascript.

  - by Vladimir

  I'm sorting array: myArray.sort(comparators.some_comparator); and I have several comparator to choose from: comparators = { asc_firstname_comparator : function(o1, o2){ ... } desc_firstname_comparator : function(o1, o2){ ... } etc... } I want to write function which returns certain comparator depending on input data. It should figure out comparator from string inputs, something like this: function chooseComparator(field, order){ return "comparators."+order+"_"+field+"_comparator"; } So is it possible to pass only function name string to sort() method or I'll need to pass reference to correct comparator somehow?

• How can I convert a specific .cs file into either a .bat or a .exe file?

  - by user2974969

  I am trying to convert around 1,900 .txp files (a proprietary Sony image format) to .png. However, the .exe program I am using to convert these files only allows me to select one file at a time. I am running Windows 7. There's a TXP.CS file in the 'src' folder of the program, so I figured that if I was able to turn that into an executable file, I'd be able to use it to mass convert these files to PNG. However, whenever I try to convert the file using csc.exe, I get the CS0246 error (the type or namespace name 'Tools' could not be found. Are you missing a using directive or an assembly reference?). I can't use Microsoft Visual Studio right now, so I'm hoping someone can walk me through this, or maybe convert the file to either a .bat or an .exe for me. Thank you. TXP.CS

• Simplest LINQ in C# troubleshooting.

  I'm trying to learn a bit of LINQ but I'm having compile issues right off the bat. Is there any specific reason why this won't work? using System; using System.Collections.Generic; using System.Linq; using System.Text; namespace HelloLINQ { class HelloLINQ { public static void Main() { Example1(); } public static void Example1() { var numbers = new int[] { 1, 5, 3, 7, 3, 8, 9, 3, 6, 6, 2 }; var under5 = from n in numbers select n; foreach (var n in under5) { Console.WriteLine(n); } } } } The error is: Could not find an implementation of the query pattern for source type 'int[]'. 'Select' not found. Are you missing a reference to 'System.Core.dll' or a using directive for 'System.Linq'?

• .NET C# MouseEnter listener on a Control WITH Scrollbar

  - by Run CMD

  As long as the mouse is over a specific control, we show some form. When the mouse leaves the control, we hide the control after a small timeout. This is standard hover behavior. However, when a control (for example a Treeview) has a scrollbar, and the mouse is ON or OVER the scrollbar, the events don't fire ... If we could get a reference to the scrollbar control, this would solve our problem, as we would add the same listener events to the scrollbar. However, the scrollbar isn't accessible as far as I know ... How can we solve this problem ?

• how to copy char * into a string and vice-versa

  - by user295030

  If i pass a char * into a function. I want to then take that char * convert it to a std::string and once I get my result convert it back to char * from a std::string to show the result. I don't know how to do this for conversion ( I am not talking const char * but just char *) I am not sure how to manipulate the value of the pointer I send in. so steps i need to do take in a char * convert it into a string. take the result of that string and put it back in the form of a char * return the result such that the value should be available outside the function and not get destroyed. If possible can i see how it could be done via reference vs a pointer (whose address I pass in by value however I can still modify the value that pointer is pointing to. so even though the copy of the pointer address in the function gets destroyed i still see the changed value outside. thanks!

• Refresh list of drawables in Eclipse?

  - by Matt Swanson

  When I add drawable resources to my project they do not show up in the list of drawables in the Reference Chooser. I checked the R file and there are references for the files. I have tried refreshing the project, cleaning the project, and fixing project properties and nothing seems to help. Sometimes a couple will randomly show up in there, but not all of them. The only consistent way I can get them to show up is to restart Eclipse. Any ideas? Thanks

• Serving images from Amazon S3 in PHP application

  - by luckytaxi

  So it just occurred to me that once I upload profile pics to S3, I have to figure out a way to keep track of the files. For example, if "susan" uploads 3 profile pics, I need to recall those 3 pictures and display it on her profile page if someone views her page. With that said, would the following work? User uploads picture from form Save file information (filename, user info, etc...) into DB and reference URL from S3 Upload photos to S3 When displaying pictures, I'll query the DB for the info and display the images from S3 accordingly.

• What is the most mature library to render equirectangular images in Flash?

  - by Dave Viner

  I have a series of equirectangular images. I'd like to display them in a custom Flash player so that the user could see the spherical nature of the images, and "look up", "look down", "look left/right" (or pan, zoom, etc). (Note that I have a long series of images, so the library must allow for dynamic loading of the images themselves, rather than having the images "baked" into the SWF player.) What is the best library to manage the display of the equirectangular images in Flash? By "best", I mean the most mature, most reliable, most robust, and fastest performing. For reference, an example of an equirectangular image can be found at http://archive.bigben.id.au/tutorials/360/background/projections.html.
