  • iphone - how to properly handle exceptional situations (signals ?)

    - by pmilosev
    Hi In my iphone app, I want to provide some sort of app termination handler that will do some final work (delete some sensitive data) before the application terminates. I want to handle as much of the termination situations as possible: 1) User terminates the app 2) The device runs out of battery 3) The system terminates the app due to some reason (e.g. out of memory or app freeze) 4) Application crashes (EXC_BAD_ACCESS or SIGSEGV) Any other exceptional situation ? What is the best way to achieve this (e.g. is applicationWillTerminate method called in situation 2) ? Is it possible to do the cleanup in a signal handler (includes iPhone Security framework calls) ? regards

  • Any way to add an observer to the head of the queue using Element#observe?

    - by Josh
    This might not be possible but before I rewrite part of my application I wanted to ask... I have a JavaScript app which creates a submit <input> and observes that input's click event using Prototype's Element#observe function. For a few particular pages on one particular site which uses this app, I need to apply some additional business logic before the code which executes normally when the button is clicked. Is there any way I can use Elemen#observe to add my new event handler before the existing event handler, so I can stop the event if these new conditions aren't met? If not I'll probably solve this the "proper" way by having the application fire a specific beforeTakingAction event and add a listener for that which prevents the application from taking it's action, but that's more complicated than this simple problem requires, and requires rewriting part of a shared application for just one user...

  • How can I switch off exception handling in MSVC?

    - by Tamara
    Does anybody know how to switch off exception handling option in MSVC? I tried to set the option 'Enable C++ exceptions' to 'NO' and I got warning: warning C4530: C++ exception handler used, but unwind semantics are not enabled. Specify /EHsc I would like to switch off the exception handler, too, but I don't know how. In my application I basically need more speer than stability, therefore I chose switching off the exception handling. I do not have any try/catch blocks, but I do use STL. When I switch the option 'Enable C++ exceptions' to 'NO' is there any way how to get rid of those warnings?

  • How to stop an activity with GL view. Application not responding

    - by David
    I have an activity that I want to programmatically stop after some elapsed time. I have a GL view running. My understanding is that the GLSurfaceView.renderer is running in its own thread, so I created a handler instantiated from the activity. In the GLSurfaceView I post a message. The handler then attempts to stop the activity with the following: onStop(); finish(); The activity seems to close. However, if I try to restart the application, I get a blank screen, the phone is practically locked up and eventually I get a message that the activity in the application is not responding. I'm also getting geting a wake lock, ie PowerManager.newWakeLock(...). When I try to release it, I get an exception. Not sure if its the GL view of the wake lock which is causing me troubles. Any ideas appreciated.

  • jQuery jqXHR - cancel chained calls, trigger error chain

    - by m0sa
    I am creating a ajax utility for interfacing with my server methods. I would like to leverage jQuery 1.5+ deferred methods from the object returned from the jQuery.ajax() call. The situation is following. The serverside method always returns a JSON object: { success: true|false, data: ... } The client-side utility initiates the ajax call like this var jqxhr = $.ajax({ ... }); And the problem area: jqxhr.success(function(data, textStatus, xhr) { if(!data || !data.success) { ???? // abort processing, trigger error } }); return jqxhr; // return to caller so he can attach his own handlers So the question is how to cancel invocation of all the callers appended success callbacks an trigger his error handler in the place mentioned with ???? ? The documentation says the deferred function invocation lists are FIFO, so my success handler is definitely the first one.

  • GetWindowLongPtr fails if called when handling WM_CREATE

    - by Semen Semenych
    Calling the GetWindowLongPtr function for a dialog box with the DWL_USER parameter fails when done from the WM_CREATE handler. It gives no error (checked that, the return value is always zero), which, according to the MSDN documentation, occurs only if SetWindowLongPtr has not been called previously. However, I call it after registering the window class, and properly call the SetWindowPos after that. Finally, calling GetWindowLongPtr in any other event handler, that is, later than WM_CREATE, works fine. Is there something I'm missing in the initialization sequence, or maybe the messages are sent in some not so obvious order?

  • Event firing sequence for a submit button.

    - by JSTyro
    Say a submit button has a click event handler as well (yes, it's wrong, but that's really the code I'm working on). And the click handler sets a value in a field of the form that's about to be submitted. So when the submit button is clicked: What will fire first, the form submit event or the click event? Will the value set in the form field by the click event submitted to the server? I think this depends on the answer to Q1. If the form is posted first, I'm guessing it won't. Note: I'm not looking for alternatives and advice. I know what the proper way of handling this will be. Just trying to understand the sequence of events and their implications.

  • In ASP.NET MVC, how does response.redirect work?

    - by Swoop
    I have used response.redirect in classic ASP and ASP.NET webforms. However, with MVC 2.0, I am running into something peculiar. I have a private method in a controller class that is used by multiple controller methods to help load and validate some information. This private method is setup to redirect if a problem is discovered to a generic error message page. The big problem I am noticing is that the calling controller class and page view attempt to complete rendering and loading before the redirect actually takes place. This is annoying in development because the View throws exceptions that I need to ignore before my generic error page finally loads. As mentioned above, I am used to the older model of response.redirect which prevented subsequent code on a page from being executed as the new page would then load. Any help or advice on redirects in MVC would be greatly appreciated.

  • Should I HttpCombine Google Jquery Hosted File?

    - by chobo2
    Hi I am using something called HttpCombiner: http://code.msdn.microsoft.com/HttpCombiner An HTTP handler that combines multiple CSS, Javascript or URL into one response for faster page load. It can combine, compress and cache response which results in faster page load and better scalability of web application It's a good practice to use many small Javascript and CSS files instead of one large Javascript/CSS file for better code maintainability, but bad in terms of website performance. Although you should write your Javascript code in small files and break large CSS files into small chunks but when browser requests those javascript and css files, it makes one Http request per file. Every Http Request results in a network roundtrip form your browser to the server and the delay in reaching the server and coming back to the browser is called latency. So, if you have four javascripts and three css files loaded by a page, you are wasting time in seven network roundtrips. Within USA, latency is average 70ms. So, you waste 7x70 = 490ms, about half a second of delay. Outside USA, average latency is around 200ms. So, that means 1400ms of waiting. Browser cannot show the page properly until Css and Javascripts are fully loaded. So, the more latency you have, the slower page loads. You can reduce the wait time by using a CDN. Read my previous blog post about using CDN. However, a better solution is to deliver multiple files over one request using an HttpHandler that combines several files and delivers as one output. So, instead of putting many or tag, you just put one and one tag, and point them to the HttpHandler. You tell the handler which files to combine and it delivers those files in one response. This saves browser from making many requests and eliminates the latency. This Http Handler reads the file names defined in a configuration and combines all those files and delivers as one response. It delivers the response as gzip compressed to save bandwidth. Moreover, it generates proper cache header to cache the response in browser cache, so that, browser does not request it again on future visit. Now I am wondering since it can handle adding links should I put in it the jquery file? The reason I am not sure is if it gets combined with my other files I think I might close the advantages of it being hosted on googles servers such as caching(my thinking is if it gets combined it will look different so even if a user has it in it's cache I am not sure if it will use the one for the cahce or not). So should I combine it or only the finals that I am using locally?

  • Programmatic binding of accelerators in wxPython

    - by Inductiveload
    I am trying to programmatically create and bind a table of accelerators in wxPython in a loop so that I don't need to worry about getting and assigning new IDs to each accelerators (and with a view to inhaling the handler list from some external resource, rather than hard-coding them). I also pass in some arguments to the handler via a lambda since a lot of my handlers will be the same but with different parameters (move, zoom, etc). The class is subclassed from wx.Frame and setup_accelerators() is called during initialisation. def setup_accelerators(self): bindings = [ (wx.ACCEL_CTRL, wx.WXK_UP, self.on_move, 'up'), (wx.ACCEL_CTRL, wx.WXK_DOWN, self.on_move, 'down'), (wx.ACCEL_CTRL, wx.WXK_LEFT, self.on_move, 'left'), (wx.ACCEL_CTRL, wx.WXK_RIGHT, self.on_move, 'right'), ] accelEntries = [] for binding in bindings: eventId = wx.NewId() accelEntries.append( (binding[0], binding[1], eventId) ) self.Bind(wx.EVT_MENU, lambda event: binding[2](event, binding[3]), id=eventId) accelTable = wx.AcceleratorTable(accelEntries) self.SetAcceleratorTable(accelTable) def on_move(self, e, direction): print direction However, this appears to bind all the accelerators to the last entry, so that Ctrl+Up prints "right", as do all the other three. How to correctly bind multiple handlers in this way?

  • Flash: How to get a list to be processed synchronous instead of asynchronous?

    - by Quandary
    Question: In Flash I have the below function. Now the problem is SaveFurniture, SavePolygons and SaveComments all save to the same XML file. Now SaveFurniture sends JSON encoded data to a ashx handler, which saves it in the xml on the server. The problem is, because flash sends the data asynchronous, the polygons get sent to the polygonsave ashx handler, but before saving of the furniture has completed, thus access error, write process already in progress... // cSaveData.SaveData(); public static function SaveData():void { trace("cSaveData.SaveData"); //NotifyASPXofNewScale(cGlobals.nPlanScale); SaveFurniture(); SavePolygons(); SaveComments(); } What's the best way to process this list, ONE AFTER ANOTHER ? Making a callback in all of them does make the program flow structure very confusing...

  • What are the requirements of a collection type when model binding?

    - by Richard Ev
    I have been reviewing model binding with collections, specifically going through this article http://weblogs.asp.net/nmarun/archive/2010/03/13/asp-net-mvc-2-model-binding-for-a-collection.aspx However, the model I would like to use in my code does not implement collections using generic lists. Instead it uses its own collection classes, which inherit from a custom generic collection base class, the declaration of which is public abstract class CollectionBase<T> : IEnumerable<T> The collections in my POSTed action method are all non-null, but contain no elements. Can anyone advise?

  • Detecting new MMS (Android 2.1)

    - by Asahi
    I'd like to recognize arrival of new MMS msg (after it is downloaded to inbox). I am doing the following: private MMSContentObserver mMmsCO; public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); h = new Handler(); mMmsCO = new MMSContentObserver(h); getContentResolver().registerContentObserver (Uri.parse("content://mms"), true, mMmsCO); } where private class MMSContentObserver extends ContentObserver { public MMSContentObserver(Handler h) { super(h); } @Override public boolean deliverSelfNotifications() { return false; } @Override public void onChange(boolean selfChange) { super.onChange(selfChange); } } However, onChange is not getting called. What am I missing? Thanks in advance.

  • How do I map nested generics in NHibernate

    - by Gluip
    In NHibernate you can map generics like this <class name="Units.Parameter`1[System.Int32], Units" table="parameter_int" > </class> But how can I map a class like this? Set<T> where T is a Parameter<int> like this Set<Parameter<int>> My mapping hbm.xml looking like this fails <class name="Set`1[[Units.Parameter`1[System.Int32], Units]],Units" table="settable"/> I simplified my mappings a little to get my point accross very clearly. Basically I want NHibernate to map generic class which has has generic type parameter. Want I understand from googling around is that NHibernate is not able to parse the name to the correct type in TypeNameParser.Parse() which result in the following error when adding the mapping to the configuration System.ArgumentException: Exception of type 'System.ArgumentException' was thrown. Parameter name: typeName@31 Anybody found a way around this limitation?

  • parallel.foreach with custom collection

    - by SchwartzE
    I am extending the System.Net.Mail.MailAddress class to include an ID field, so I created a new custom MailAddress class that inherited from the existing class and a new custom MailAddressCollection class. I then overrode the existing System.Net.Mail.MailMessage.To to use my new collection. I would like to process the recipients in parallel, but I can't get the syntax right. This is the syntax I am using. Parallel.ForEach(EmailMessage.To, (MailAddress address) => { emailService.InsertRecipient(emailId, address.DisplayName, address.Address, " "); }); I get the following errors: The best overloaded method match for 'System.Threading.Tasks.Parallel.ForEach(System.Collections.Generic.IEnumerable, System.Action)' has some invalid arguments Argument 1: cannot convert from 'EmailService.MailAddressCollection' to 'System.Collections.Generic.IEnumerable' What syntax do I need to use custom collections?

  • UnicodeDecodeError from a GET-parameter in webapp2

    - by Aneon
    I'm getting a UnicodeDecodeError when recieving a GET-parameter from webapp2 that contains unicode characters, and then using it to do a NDB query. I get the same error message when manually running a unicode() on the parameter in the handler, so there either seems to be a problem in webapp2's URL routing or I've missed something. Preferably, all GET-parameters should be converted to unicode before getting passed into the handler so I don't need to do manual conversions in all of my handlers. I actually think it's worked before in an earlier version. The full error message read: UnicodeDecodeError: 'ascii' codec can't decode byte 0xc3 in position 1: ordinal not in range(128) The GET-parameter contains the following string: göteborg. It looks fine when I raise an Exception on it, but gives me an error when I (or NDB) use unicode() on it. EDIT: In NDB, it fails on the following code: File "C:\Program Files (x86)\Google\google_appengine\google\appengine\api\datastore_types.py", line 1562, in PackString pbvalue.set_stringvalue(unicode(value).encode('utf-8')) Thanks.

  • boost variant static_visitor problem picking correct function

    - by Steve
    I'm sure I'm having a problem with template resolution here, but I'm not sure why I'm having the problem. I have a static visitor I'm passing to boost variant where i've had to do template specialization for certain cases. The case for everything except for MyClass should throw in the static_visitor below. Unfortunately, when the visitor is applied to pull a MyClass out, it selects the most generic case rather than the exact match. I would type each case explicitly, but that will be rather long. So, why is the compiler resolving the most generic case over the exact match, and is there anyway to fix it template<> class CastVisitor<MyClass>:public boost::static_visitor<MyClass> { public: template<typename U> MyClass operator()(const U & i) const { throw std::exception("Unable to cast"); } MyClass operator()(const MyClass& i) { return i; } };

  • How to add javascript to YII correctly?

    - by RD.
    I want to create several javascript function that will be needed on different pages. Most will be relevant only to one page, but some to several. I know if I add general conversion functions, it would be a good idea to just create a new javascript file and put all these generic functions into that one file. Bringing me to my first question: Where would you store the generic javascript file? In "protected"? Which subfolder? Then, I need to address the placement of other javascript code. If I have javascript that will only be used on one page, should I use this technique or should I stick to a similar approach as above? The emphasis is on doing it correctly. I want to fall exactly in line with the yii framework.
