  • How to find out if a method exists in Obj-C when given an NSString

    - by Justin
    I have a method as an NSString *. If it exists, I want to call it, and if not, do nothing. SEL eventSelector = NSSelectorFromString(eventSelectorStr); if ([delegate respondsToSelector:eventSelector]) { [delegate performSelector:eventSelector]; [delegate adapterDidFinishAdRequest:self]; } else { // Does not implement selector } This code does not work, since NSSelectorFromString will register the string as a selector, so respondsToSelector:eventSelector will cause a crash because the selector is actually invalid.

  • find: missing argument to -exec in bash script

    - by Mephi_stofel
    The following works fine when I type it exactly in the command line: find /<some_path>/{epson,epson_laser,epson_inkjet} -iname "*.ppd" -exec grep "\*ModelName\:" {} \; | sed 's/.*\"\(.*\)\"/\1/' However, when I try to call the following from a bash script I get find: missing argument to -exec'. I have also tried the following (in many variants): eval find "$1" -iname "*.ppd" -exec 'bash -c grep "\*ModelName\:" "$1" | sed "s/.*\"\(.*\)\"/\1/" \; as was mentioned in find-exec-echo-missing-argument-to-exec.

  • Unity 2.0 and policy injection in .config

    - by marcusoft.net
    I want to use unity (2.0) to resolve my dependencies in a way so that i can configure policy injection (policies, matching rules and call handlers) in the .config file. Or an other way to put it; i want my resolved objects to be "policy enabled", so that i can add and change to policies in config without have to recompile. Any ideas on how to do that?

  • What happens in memory when calling a function with literal values?

    - by Drise
    Suppose I have an arbitrary function: void someFunc(int, double, char); and I call someFunc(8, 2.4, 'a');, what actually happens? How does 8, 2.4, and 'a' get memory, moved into that memory, and passed into the function? What type of optimizations does the compiler have for situations like these? What if I mix and match parameters, such like someFunc(myIntVar, 2.4, someChar);? What happens if the function is declared as inline?

  • Can you use Ant to Build/Modify XML files?

    - by user369701
    I am quite new to ant and have been looking at the tasks. I am trying to generate an xml file. Do I need to call an external process or does ant have some way to do this? It could be as simple as sending a string to a txt file and saving it as a .xml. Is it possible?

  • General question about Ruby Eigenclass/Singleton

    - by Dex
    module MyModule def my_method; 'hello'; end end class MyClass class << self include MyModule end end MyClass.my_method # => "hello I'm unsure why "include MyModule" needs to be in the eigenclass in order to be called using just MyClass. Why can't I go: X = MyClass.new X.my_method How is this type of pattern useful if I can't call it from an instance?

    - by rasouza
    I have a model which is referenced to a table registries extending Zend_Db and some methods which bascially uses fetchAll() all the time.

  • how to watch input buttons with specified name?

    - by user393087
    For example I have long list of buttons: <input type=button name=clickbutton onclick='dosomething(this)'> But instead of putting call to the same funcion in every button it would be more rational to add a single listening event that would wait for click of that button with this name. But again, there are maany this buttons so I need pass clicked object to a function. For example this function must update a textarea field that is adjacent (nextSibling) to this button.

  • 'Invalid conversion from some_type** to const some_type**'

    - by petersohn
    I've got a function that requires const some_type** as an argument (some_type is a struct, and the function needs a pointer to an array of this type). I declared a local variable of type some_type*, and initialized it. Then I call the function as f(&some_array), and the compiler (gcc) says: error: invalid conversion from ‘some_type**’ to ‘const some_type**’ What's the problem here? Why can't I convert a variable to const?

  • Recursive insert-method for a linked list

    - by user3726477
    I'm learning C# and I've made a recursive insert-method for a linked list: public static int recursiveInsert(ref int value, ref MyLinkedList list) { if (list == null) return new MyLinkedList(value, null); else { list.next = recursiveInsert(ref int value, ref list.next); return list; } } How would you modify this method to make the recursive call look like this: recursiveInsert(value, ref list.next) instead of: list.next = recursiveInsert(ref int value, ref list.next);

  • Using PHP5s SOAP Client to send data to an ASP/.NET based SOAP server.

    - by user325143
    I am trying to write a snippet of PHP to connect to a third party's API via SOAP to enter some data into their database. The API requires me to pass several mandatory fields for every call (username, password, companyid, entitytype) in addition to the mandatory data fields. It also requires me to call the "ValidateEntity" funciton before calling the "CreateEntity" function. Documentation can be found here: http://wiki.agemni.com/Getting_Started/APIs/Database_API I have never worked with SOAP before, so I am very new to this. Here is what I have so far: error_reporting(E_ALL); ini_set('display_errors', '1'); $client = new SoapClient("http://agemni.com/AgemniWebservices/service1.asmx?WSDL", array('trace'=> true)); $options = array( 'username' => "myuser", 'password' => "mypassword", 'companyid' => myID, 'entitytype' => 2 ); $params = array( 'fname' => "John", 'lname' => "Doe", 'phone' => "859-333-3333", 'zip' => "40332", 'area id' => "12345", 'lead id' => "28222", 'contactdate' => "4/10/2010" ); $validate = $client->__soapCall("ValidateEntity", array($params), array($options)); $client->__soapCall("CreateEntity", array($params), array($options)); echo "<pre>"; var_dump($client-> __getLastRequestHeaders()); var_dump($client-> __getLastRequest()); var_dump($client-> __getLastResponseHeaders()); var_dump($client-> __getLastResponse()); var_dump($result); echo "</pre>"; Upon executing this code, I get the following error: Fatal error: Uncaught SoapFault exception: [Client] SOAP-ERROR: Encoding: object hasn't 'objecttype' property in /www/tmp/index-soap.php:24 Stack trace: #0 /www/tmp/index-soap.php(24): SoapClient->__soapCall('ValidateEntity', Array) #1 {main} thrown in /www/stealth/tmp/index-soap.php on line 24 I guess my question is.. am I even going about doing this the right way? I know this is a very broad question, but I appreciate any advice you can give me about making this work. Please let me know if you require more detail. Thanks!

  • Basic visual studio intellisense question

    - by maxp
    Ive used visual studio for years, but the answer this eludes me: When intellisense pops up, for a method call that takes more than one parameter, the summary for the first parameter is shown. The only way i've found to show the summary for the following parameter(s) is to either supply each parameter or just hit comma until i get the one im looking for. Ive tried ctrl+right arrow, shift + right arrow etc etc, without success. Just curious is all.

  • Codeigniter: user defined helper function does not load.

    - by cbrandolino
    Hi everybody. I made a custom helper extending the system string_helper.php. I placed it in my /application/helpers folder, called MY_string_helper.php as required, unit-tested its functions. Now, when I try to call one of its functions from a model, it does not work. The functions in the default string helper work, instead. It looks like my extension is not loaded for some reasons. Thanks a lot, and happy holidays.

  • How to add a cross-browser mouse wheel function to a div in javascript?

    - by Shaunwithanau
    I am trying to stop the default mouse wheel event that is called on the window and on a div and call my own function instead on the div. I need this to be cross-browser (without the use of a library. I know I need to use an eventListener and I think have to use both onmousewheel and DOMMouseScroll (for FF) but I think am getting caught up in the implementation somewhere. I appreciate any and all help.

  • Can I Force A ASP.Net Website to Show Time in A Specific Time Zone?

    - by KevDog
    I have a client request that all times be displayed in Pacific Time Zone, regardless of client settings. I'd like to avoid a scenario where I have to call a function for every time display and instead have a single point where I can make the switch. I'm thinking a custom culture might do the trick, but I wanted to ask before I set off down a potentially blind alley (or miss something trivially easy).

  • Sound Complete Not Firing (AS3)

    - by JasonMc92
    I have a bit of a quandary. I need to call a function inside a MovieClip once a particular sound has finished playing. The sound is played via a sound channel in an external class which I have imported. Playback is working perfectly. Here is the relevent code from my external class, Sonus. public var SFXPRChannel:SoundChannel = new SoundChannel; var SFXPRfishbeg:Sound = new sfxpr_fishbeg(); var SFXPRfishmid:Sound = new sfxpr_fishmid(); var SFXPRfishend3:Sound = new sfxpr_fishend3(); var SFXPRfishend4:Sound = new sfxpr_fishend4() public function PlayPrompt(promptname:String):void { var sound:String = "SFXPR" + promptname; SFXPRChannel = this[sound].play(); } This is called via an import in the document class "osr", thus I access it in my project via "osr.Sonus.---" In my project, I have the following line of code. osr.Sonus.SFXPRChannel.addEventListener(Event.SOUND_COMPLETE, promptIsFinished); function prompt():void { var level = osr.Gradua.Fetch("fish", "arr_con_level"); Wait(true); switch(level) { case 1: osr.Sonus.PlayPrompt("fishbeg"); break; case 2: osr.Sonus.PlayPrompt("fishmid"); break; case 3: osr.Sonus.PlayPrompt("fishend3"); break; case 4: osr.Sonus.PlayPrompt("fishend4"); break; } } function Wait(yesno):void { gui.Wait(yesno); } function promptIsFinished(evt:Event):void { Wait(false); } osr.Sonus.PlayPrompt(...) and gui.Wait(...) both work perfectly, as I use them in other contexts in this part of the project without error. Basically, after the sound finishes playing, I need Wait(false); to be called, but the event listener does not appear to be "hearing" the SOUND_COMPLETE event. Did I make a mistake somewhere? For the record, due to my project structure, I cannot call the appropriate Wait(...) function from within Sonus. Help?
