• Loop through all subclasses in an Android view?

  - by Slapout

  I’m working on a game for Android. To help implement it, my idea is to create a subclass of a view. I would then insert several instances of this class as children of the main view. Each instance would handle detecting when it was pressed (via OnTouchListener). The problem I’m having now is how do I loop through all these sub-views so I can read their statuses and process them? (I.e. when they all reach a certain state something should happen). Or is there a better way to have several objects on the screen that respond to touch and whose status I can check?

• Traditional loop versus Action delegate in C#

  - by emddudley

  After learning about the Action delegate in C# I've been looking for ways I can best use it in my code. I came up with this pattern: Action<string> DoSomething = (lSomething) => { // Do something }; DoSomething("somebody"); DoSomething("someone"); DoSomething("somewhere"); If I were to have used a traditional loop, it would look something like this: List<string> lSomeList = new List<string>(); lSomeList.Add("somebody"); lSomeList.Add("someone"); lSomeList.Add("somewhere"); foreach (string lSomething in lSomeList) { // Do something } Are there any appreciable differences between the two? To me they look equally easy to understand and maintain, but are there some other criteria I might use to distinguish when one might be preferred over the other?

• Java Loop every minute.

  - by Robert

  I want to write a loop in Java that firs starts up and goes like this: while (!x){ //wait one minute or two //execute code } I want to do this so that it does not use up system resources. What is actually going on in the code is that it goes to a website and checks to see if something is done, if it is not done, it should wait another minute until it checks again, and when its done it just moves on. Is their anyway to do this in java? I googled it but didnt find anything. Thanks

• Windows Command Line

  - by Markus O'Reilly

  Does anyone know how to break out of a for loop when it's typed directly into the windows command-line? I know you can use gotos and labels to break out of it when it's in a batch file, but I can't find anything about breaking out of one on the command line. Here's a simple example: C:> for /l %i in (1,0,1) do @ping -n 1 google.com || (echo ^G & msg user "Google is down!" & QUIT) This should infinitely ping google.com. If it ever fails, it beeps (echo ^G), displays a message box to the user "user" that says "Google is down!", and QUITs. I don't know how to do the quit part though. I guess I could do something like taskkill /f /im cmd.exe, but I was looking for something more elegant. Any tips?

• using array_sum() in a while loop

  - by m477

  Hi folks, I'm learning PHP. Having trouble understanding why this piece of code isn't working. In particular: why is the result of array_sum($x) (1596) greater than $cap? Perhaps I'm not understanding the nature of while loops, but it seems to me (looking at a print_r($x)), the loop should cut out a step before it actually does. <?php function fibonacci_sum($cap = 1000){ list( $cur, $nxt, $seq ) = array( 0, 1, array() ); while ( array_sum($seq) < $cap ) { $seq[] = $cur; $add = $cur + $nxt; $cur = $nxt; $nxt = $add; } return $seq; } $x = fibonacci_sum(); echo array_sum($x); ?> Any insight is appreciated. Best, matt

• How to run infinitely script in background on Linux?

  - by Andrew Bashtannik

  I have a PHP script with infinite loop. I need this script running forever. So, I run php /path/to/script.php > /dev/null & And it works in background in my current user's security context. But when I close terminal window (log off), of course, CentOS Linux kills my program. I see two guesses: run from a different user in background or make a daemon. I need help in each situation. Thanks a lot!

• missing value true / false: error in loop not in one-off

  - by vincent hay

  I am new on R and I have a problem with a test in a loop that I want to code. With a data frame (tabetest) like the one here after: Date 25179M103 1 14977 77.7309 2 14978 77.2567 3 14979 77.7507 I have: if(tabetest[3,"Date"]-tabetest[1,"Date"]1){print("ok")} [1] "ok" But: j=1 > position = 1 > price=tabetest for (i in 1:nrow(tabetest)-position){if(tabetest[i+position,"Date"]-tabetest[position,"Date"]>20){price[i+position,j]=price[i+position,j]/price[position,j]-1};position=position+1} Returns an error. R says that there is a missing value where true/false is required in: if (tabetest[i + position, "Date"] - tabetest[position, "Date"] > I have spent quite some time on that error but still don't understand where it comes from. Thanks for your help, Vincent

• WPF application which calls an API, which needs a message pump

  - by Griffin

  I have a WPF application that calls an API to operate a device (a scanner). This API is COM based, and internally has a hidden window that the scanner sends messsages too. The intent of the API is to turn those windows messages into COM events. The problem is that the WPF application doesn't have a message pump, and therefore none of the messages are being delivered to the hidden window. Therefore none of the events are fired and it looks like the scanner is not responding. How should I create a message loop in the WPF application that will be able to dispatch messages to the invisible window?

• C# to loop through folder until it finds the correct files

  - by Liton Uddin

  I’m running a batch to do an update to my sql table. I’m using windows scheduler to run the batch file. Each day files come in at different time. Sometime they come in after my scheduled time therefore the batch file doesn’t run when there’s no file before the scheduled task in the folder. I want to create a c# program where it will loop through the folder until it finds the files and then move to the next step in the batch file. Basically my goal is to create a program that will look for those particular files and once they finds the correct files then it will start the update. I’m new to programming and need some direction. Can someone please help me with this? Thanks.

• Deselecting a form input and waiting for a function before submitting

  - by blcArmadillo

  I have a form with an input field where a user enters a unique identifier. I then have some jQuery code that upon the user moving away from the input field (blur) goes out and fetches details about the part and populates some fields on the page. The problem is if the user clicks the submit button before moving out of the input field the jQuery code never has a chance to load in the data and populate the necessary fields. Whats the best way to go about doing this? I thought about maybe setting the focus to body and then having an infinite loop that keeps checking the page until all fields that should be filled in have been filled in but I feel like some sort of event based solution would be better than unpredictable infinite loops. Any ideas?

• Dynamic Selectors with Jquery with php while loop

  - by Anders Kitson

  I have a while loop which creates a list of anchor tags each with a unique class name counting from 1 to however many items there are. I would like to change a css attriubute on a specific anchor tag and class when it is clicked so lets say the background color is changed. Here is my code while($row = mysql_fetch_array($results)){ $title = $row['title']; $i++; echo "<a class='$i'>$title</a> } I would like my jquery to look something like this, it is obviously going to be more complicated than this I am just confused as where to start. $(document).ready(function() { $('a .1 .2 .3 .4 and so on').click(function() { $('a ./*whichever class was clicked*/').css('background':'red'); }); });

• alias_attribute and creating and method with the original attribute name causes a loop

  - by Tiago

  Im trying to dynamically create a method chain in one attribute in my model. By now I have this function: def create_filtered_attribute(attribute_name) alias_attribute "#{attribute_name}_without_filter", attribute_name define_method "#{attribute_name}" do filter_words(self.send("#{attribute_name}_without_filter")) end end so I receive a string with the attribute name, alias it for '*_without_filter*' (alias_method or alias_method_chain fails here, because the attribute isnt there when the class is created), and I create a new method with the attribute name, where I filter its contents. But somehow, when I call *"#{attribute_name}_without_filter"* it calls my new method (i think because the alias_attribute some how), and the program goes into a stack loop. Can someone please enlighten me on this.

• What languages have a while-else type control structure, and how does it work?

  - by Dan

  A long time ago, I thought I saw a proposal to add an else clause to for or while loops in C or C++... or something like that. I don't remember how it was supposed to work -- did the else clause run if the loop exited normally but not via a break statement? Anyway, this is tough to search for, so I thought maybe I could get some CW answers here for various languages. What languages support adding an else clause to something other than an if statement? What is the meaning of that clause? One language per answer please.

• Requesting information from the user inside a GTK main loop

  - by Victor Stanciu

  Hello, I am learning Python by building a simple PyGTK application that fetches data from some SVN repositories, using pysvn. The pysvn Client has a callback you can specify that it calls when Subversion needs authentication information for a repository. When that happens, I would like to open a dialog to ask the user for the credentials. The problem is, it seems the callback is called inside the GTK main loop, so it's basically called on every tick. Is there a way to prevent this? Perhaps by opening the dialog in a new thread? But then how do I return the tuple with the user data to the callback so it can return it to the pysvn.Client?

• Handle order dependence in for loops

  - by Matt

  Hey all, I'm making a templating system where I instantiate each tag using a foreach loop. The issue is that some of the tags rely on each other so, I'm wondering how to get around that ordering from the looping. Here's an example: Class A { public $width; __construct() { $this->width = $B->width(); // Undefined! Or atleast not set yet.. } } Class B { private $width; __construct() { $this->width = "500px"; } __tostring() { return "Hello World!"; } } Template.php $tags = array("A", "B"); foreach ($tags as $tag) { $TagObj[$tag] = new $tag(); } echo $TagObj['A']->width; // Nadamundo! I know this has applications elsewhere and I'm sure this has been solved before, if someone could enlighten me or point me in the right direction that'd be great! Thanks! Matt Mueler
