  • Why is SwiftMailer throwing "Internal Server Error"?

    - by Josamoto
    I am using Symfony + SwiftMailer and getting the following error from SwiftMailer: 500 | Internal Server Error | Swift_TransportException Expected response code 220 but got code "", with message "" and can't figure out why. I am using hMailServer on my local machine, and have setup my factories.yml file (as I'm using Symfony) as follows: mailer: class: sfMailer param: logging: %SF_LOGGING_ENABLED% charset: %SF_CHARSET% delivery_strategy: realtime transport: class: Swift_SmtpTransport param: host: splodge.loc port: 25 encryption: ~ username: ~ password: ~ I'm using the following code to send: $message = $this->getMailer()->compose( '[email protected]', '[email protected]', 'Reset Password', 'Message' ); $result = $this->getMailer()->send($message); Has anyone had an issue like this before? I have found that sometimes, and very randomly, the send goes through, but every other time, I get the above error message. So constantly refreshing the page that sends the mail, fails unpredictably, and as the code sometimes works, it's kinda hard to figure out what's wrong. Any help will be highly appreciated!

  • Why is -[UISwitch superlayer] being called?

    - by Jonathan Sterling
    I've got sort of a crazy thing going on where I have an NSProxy subclass standing in for a UISwitch. Messages sent to the proxy are forwarded to the switch. Please don't comment on whether or not this is a good design, because in context, it makes sense as an incredibly cool thing. The dealio is that when I try to add this object as an accessory view to a UITableViewCell, I get the following crash: Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '*** -[UISwitch superlayer]: unrecognized selector sent to instance 0x5889740' Yes, I could just set the proxy's target as the accessory view, but then I would have to keep track of the proxy so that I could release it at the right time. So, what I really want is to be able to have the proxy retained by the table cell, and released when it is removed from the view just like a normal accessory view. So, why is -[UISwitch superlayer] (a method which does not exist) being called, and how do I save the world?

  • C++ Why is the converter constructor implicitly called?

    - by ShaChris23
    Why is the Child class's converter constructor called in the code below? I mean, it automatically converts Base to Child via the Child converter constructor. The code below compiles, but shouldn't it not compile since I haven't provided bool Child::operator!=(Base const&)? class Base { }; class Child : public Base { public: Child() {} Child(Base const& base_) : Base(base_) { std::cout <<"should never called!"; } bool operator!=(Child const&) { return true; } }; void main() { Base base; Child child; if(child != base) std::cout << "not equal"; else std::cout << "equal"; }

  • Why is there no IronPerl (Perl for .Net)?

    - by Renaud Bompuis
    I'm a bit disappointed that there doesn't seem to be any effort to make Perl a first-class citizen of the .Net world. I've read a few 'reasons' in the past but I don't see why they can't be overcome (different garbage collectors, hard-to-parse syntax, part of CPAN modules couldn't be ported, different communities, ...). Activestate has a Perl.Net product but it's a hack (in the good sense) around a standard interpreter and some syntactic sugar to interoperate with .Net assemblies. A few years ago they stopped they visual studio integration of Perl citing lack of interest. That was a while ago, before all the changes to .Net to make it more 'dynamic'. Am I the only one who yearns for IronPerl?

  • Why is UIApplicationWillChangeStatusBarFrameNotification not sent when the in-call status bar is sho

    - by Sbrocket
    I've been trying to listen for changes in the status bar height – such as when the in-call status bar is shown or hidden – by listening for the UIApplicationWillChangeStatusBarFrameNotification notification to be sent. Fairly straightforward code here... [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(statusBarWillChangeFrame:) name:UIApplicationWillChangeStatusBarFrameNotification object:nil]; But the notification never seems to be sent in that case, either on the Simulator by using the "Toggle In-Call Status Bar" option or on the device when a call ends with the application open. In addition, the similar UIApplicationDelegate method is not called. According to the documentation, UIApplicationWillChangeStatusBarFrameNotification Posted when the application is about to change the frame of the status bar. The userInfo dictionary contains an NSValue object that encapsulates a CGRect structure expressing the location and size of the new status bar frame. Use UIApplicationStatusBarFrameUserInfoKey to access this value. Can anyone explain why this notification is not being sent in response to the in-call status bar being shown or hidden? According to the documentation, it should be.

  • Why do these nested while loops not work?

    I tried and tried and tried to get this code to work and kept coming up with zilch. So I decided to try it using "for loops" instead and it worked first try. Could somebody tell me why this code is no good? <?php $x = $y = 10; while ($x < 100) { while ($y < 100) { $num = $x * $y; $numstr = strval($num); if ($numstr == strrev($numstr)) { $pals[] = $numstr; } $y++; } $x++; } ?>

  • Why is invalid value being thrown?

    - by Nathan Koop
    I've got a DevExpress TextEdit which is databound to a dataset. The field is an optional percentage, (datatype double). When the record gets loaded and there is no value in the field, everything is fine. However, if you type something into the field (IE 100) and then want to remove it afterwards, I get an Invalid Value, error. Why does this occur, and how can I remove it? I do not have any mask or any sort of explicit validation on this field.

  • PHP: why is this null different from the other null

    - by matthy
    hi i tried 2 things what should be the same however it my testing says different does anyone know why the only thing i do is put it in a variable... if ($_SESSION[$something] === null) echo("this is null"); $_SESSION[$something] does not exists so it indeed says: "this is null". now look at this $theSession = $_SESSION[$something]; if (theSession === null) echo("this is null"); now it does not say "this is null" while it should be exactly the same right?

  • Why use "foo" in coding examples? [closed]

    - by ThePower
    Possible Duplicates: To foo bar, or not to foo bar: that is the question. Bit of a general question here, but it's something I would like to know! Whenever I am looking for resolutions to my C# problems online, I always come across "foo" being used as an example. Does this represent anything or is it just one of those unexplained catchy object names, used by many people in examples?

  • Why are getters prefixed with the word "get"?

    - by Joey
    Generally speaking, creating a fluid API is something that makes all programmers happy; Both for the creators who write the interface, and the consumers who program against it. Looking beyond conventions, why is it that we prefix all our getters with the word "get". Omitting it usually results in a more fluid, easy to read set of instructions, which ultimately leads to happiness (however small or passive). Consider this very simple example. (pseudo code) Conventional: person = new Person("Joey") person.getName().toLower().print() Alternative: person = new Person("Joey") person.name().toLower().print() Of course this only applies to languages where getters/setters are the norm, but is not directed at any specific language. Were these conventions developed around technical limitations (disambiguation), or simply through the pursuit of a more explicit, intentional feeling type of interface, or perhaps this is just a case of trickle a down norm. What are your thoughts? And how would simple changes to these conventions impact your happiness / daily attitudes towards your craft (however minimal). Thanks.

  • HttpModule Init method is called several times - why?

    - by MartinF
    I was creating a http module and while debugging I noticed something which at first (at least) seemed like weird behaviour. When i set a breakpoint in the init method of the httpmodule i can see that the http module init method is being called several times even though i have only started up the website for debugging and made one single request (sometimes it is hit only 1 time, other times as many as 10 times). I know that I should expect several instances of the HttpApplication to be running and for each the http modules will be created, but when i request a single page it should be handled by a single http application object and therefore only fire the events associated once, but still it fires the events several times for each request which makes no sense - other than it must have been added several times within that httpApplication - which means it is the same httpmodule init method which is being called every time and not a new http application being created each time it hits my break point (see my code example at the bottom etc.). What could be going wrong here ? is it because i am debugging and set a breakpoint in the http module? It have noticed that it seems that if i startup the website for debugging and quickly step over the breakpoint in the httpmodule it will only hit the init method once and the same goes for the eventhandler. If I instead let it hang at the breakpoint for a few seconds the init method is being called several times (seems like it depends on how long time i wait before stepping over the breakpoint). Maybe this could be some build in feature to make sure that the httpmodule is initialised and the http application can serve requests , but it also seems like something that could have catastrophic consequences. This could seem logical, as it might be trying to finish the request and since i have set the break point it thinks something have gone wrong and try to call the init method again ? soo it can handle the request ? But is this what is happening and is everything fine (i am just guessing), or is it a real problem ? What i am specially concerned about is that if something makes it hang on the "production/live" server for a few seconds a lot of event handlers are added through the init and therefore each request to the page suddenly fires the eventhandler several times. This behaviour could quickly bring any site down. I have looked at the "original" .net code used for the httpmodules for formsauthentication and the rolemanagermodule etc but my code isnt any different that those modules uses. My code looks like this. public void Init(HttpApplication app) { if (CommunityAuthenticationIntegration.IsEnabled) { FormsAuthenticationModule formsAuthModule = (FormsAuthenticationModule) app.Modules["FormsAuthentication"]; formsAuthModule.Authenticate += new FormsAuthenticationEventHandler(this.OnAuthenticate); } } here is an example how it is done in the RoleManagerModule from the .NET framework public void Init(HttpApplication app) { if (Roles.Enabled) { app.PostAuthenticateRequest += new EventHandler(this.OnEnter); app.EndRequest += new EventHandler(this.OnLeave); } } Do anyone know what is going on? (i just hope someone out there can tell me why this is happening and assure me that everything is perfectly fine) :) UPDATE: I have tried to narrow down the problem and so far i have found that the Init method being called is always on a new object of my http module (contary to what i thought before). I seems that for the first request (when starting up the site) all of the HttpApplication objects being created and its modules are all trying to serve the first request and therefore all hit the eventhandler that is being added. I cant really figure out why this is happening. If i request another page all the HttpApplication's created (and their moduless) will again try to serve the request causing it to hit the eventhandler multiple times. But it also seems that if i then jump back to the first page (or another one) only one HttpApplication will start to take care of the request and everything is as expected - as long as i dont let it hang at a break point. If i let it hang at a breakpoint it begins to create new HttpApplication's objects and starts adding HttpApplications (more than 1) to serve/handle the request (which is already in process of being served by the HttpApplication which is currently stopped at the breakpoint). I guess or hope that it might be some intelligent "behind the scenes" way of helping to distribute and handle load and / or errors. But I have no clue. I hope some out there can assure me that it is perfectly fine and how it is supposed to be?

  • Why don't purely functional languages use reference counting?

    - by Zifre
    In purely functional languages, data is immutable. With reference counting, creating a reference cycle requires changing already created data. It seems like purely functional languages could use reference counting without worrying about the possibility of cycles. Am is right? If so, why don't they? I understand that reference counting is slower than GC in many cases, but at least it reduces pause times. It would be nice to have the option to use reference counting in cases where pause times are bad.

  • Why does x86 WiX installer on Vista x64 not write keys to WOW6432Node in the registry

    - by Ryan Conrad
    I have an installer that writes to HKLM\Software\DroidExplorer\InstallPath. On any x86 machine it writes just fine to the expected location, on Windows XP x64 and Windows 7 x64 it also writes to the expected location, which is actually HKLM\Software\WOW6432Node\DroidExplorer\InstallPath. Later on during the install, my bootstrapper, which is also x86, attempts to read the value. On all x86 Windows machines it is successful, and on Windows XP x64 and Windows 7 x64, but Windows Vista x64 is unable to locate the key. If I look in the registry, it doesn't actually write it to WOW6432Node on Vista, it writes it to Software\DroidExplorer\InstallPath If I do not forcefully tell the installer to write to WOW6432Node, it writes the value to Software\DroidExplorer\InstallPath, but the bootstrapper still trys to look in WOW6432Node because of the Registry Reflection. This is on all x64 systems. Why is Vista x64 the only one I have this issue with? Is there a way around this?

I have the sound exporting to ActionScript with the link identifier 'sound_naturally', not exported to the first frame. I don't understand why it's not working. I did like the exact same thing like 3 hours ago and it worked fine, but I lost the file so I had to redo it and now it won't work at all. Using Flash 10 with ActionScript 2.0

  • Why does Java read its default settings from the system

    - by Bozho
    Java is reading the locale, timezone and encoding information (and perhaps more) from the system it is installed on. This often brings bad surprises (brought me one just yesterday). Say your development and production servers are set to have TimeZone GMT+2. Then you deploy on a production server set to GMT. a 2-hour shift may not be easy to observe immediately. And although you can pass a TimeZone to your calendars, APIs might be instantiating calendars (or dates) using the default timezone. Now, I know one should be careful with these settings, but are easy to miss, hence make programs more error-prone. So, why doesn't Java have its own defaults - UTF-8, GMT, en_US (yes, I'm on non-en_US locale, but having it as default is fine). Applications could read the system settings via some API, if needed. Thus programs would be more predictable. So, what is the reason behind this decision?

  • Why doesn't Visual Studio show an exception message when my exception occurs in a static constructor

But in the static constructor I get no such message. I am stepping through line-by-line, so I know that I'm getting to that line and no further. Why is this?
