  • Arrays not counting correctly

    - by Nick Gibson
    I know I was just asking a question earlier facepalm This is in Java coding by the way. Well after everyones VERY VERY helpful advice (thank you guys alot) I managed to get over half of the program running how I wanted. Everything is pointing in the arrays where I want them to go. Now I just need to access the arrays so that It prints the correct information randomly. This is the current code that im using: http://pastebin.org/301483 The specific code giving me problems is this: long aa; int abc; for (int i = 0; i < x; i++) { aa = Math.round(Math.random()*10); String str = Long.toString(aa); abc = Integer.parseInt(str); String[] userAnswer = new String[x]; if(abc > x) { JOptionPane.showMessageDialog(null,"Number is too high. \nNumber Generator will reset."); break; } userAnswer[i] = JOptionPane.showInputDialog(null,"Question "+quesNum+"\n"+questions[abc]+"\n\nA: "+a[abc]+"\nB: "+b[abc]+"\nC: "+c[abc]+"\nD: "+d[abc]); answer = userAnswer[i].compareTo(answers[i]); if(answer == 0) { JOptionPane.showMessageDialog(null,"Correct. \nThe Correct Answer is "+answers[abc]+""+i); } else { JOptionPane.showMessageDialog(null,"Wrong. \n The Correct Answer is "+answers[abc]+""+i); }//else

  • Best practice on structuring asynchronous mailers (using Sidekiq)

    - by gbdev
    Just wondering what's the best way to go about structuring asynchronous mailers in my Rails app (using Sidekiq)? I have one ActionMailer class with multiple methods/emails... notifier.rb: class Notifier < ActionMailer::Base default from: "\"Company Name\" <[email protected]>" default_url_options[:host] = Rails.env.production? ? 'domain.com' : 'localhost:5000' def welcome_email(user) @user = user mail to: @user.email, subject: "Thanks for signing up!" end ... def password_reset(user) @user = user @edit_password_reset_url = edit_password_reset_url(user.perishable_token) mail to: @user.email, subject: "Password Reset" end end Then for example, the password_reset mail is sent in my User model by doing... user.rb: def deliver_password_reset_instructions! reset_perishable_token! NotifierWorker.perform_async(self) end notifier_worker.rb: class NotifierWorker include Sidekiq::Worker sidekiq_options queue: "mail" def perform(user) Notifier.password_reset(user).deliver end end So I guess I'm wondering a couple things here... Is it possible to define many "perform" actions in one single worker? By doing so I could keep things simple (one notifier/mail worker) as I have it and send many different emails through it. Or should I create many workers? One for each mailer (e.g. WelcomeEmailWorker, PasswordResetWorker, etc) and just assign them all to use the same "mail" queue with Sidekiq. I know it works as it is, but should I break out each of those mail methods (welcome_email, password_reset, etc) into individually mailer classes or is it ok to have them all under one class like Notifier? Really appreciate any advice here. Thanks!

  • Need help getting parent reference to child view controller

    - by Andy
    I've got the following code in one of my view controllers: - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { switch (indexPath.section) { case 0: // "days" section tapped { DayPicker *dayPicker = [[DayPicker alloc] initWithStyle:UITableViewStylePlain]; dayPicker.rowLabel = self.activeDaysLabel; dayPicker.selectedDays = self.newRule.activeDays; [self.navigationController pushViewController:dayPicker animated:YES]; [dayPicker release]; break; ... Then, in the DayPicker controller, I do some stuff to the dayPicker.rowLabel property. Now, when the dayPicker is dismissed, I want the value in dayPicker.rowLabel to be used as the cell.textLabel.text property in the cell that called the controller in the first place (i.e., the cell label becomes the option that was selected within the DayPicker controller). I thought that by using the assignment operator to set dayPicker.rowLabel = self.activeDaysLabel, the two pointed to the same object in memory, and that upon dismissing the DayPicker, my first view controller, which uses self.activeDaysLabel as the cell.textLabel.text property for the cell in question, would automagically pick up the new value of the object. But no such luck. Have I missed something basic here, or am I going about this the wrong way? I originally passed a reference to the calling view controller to the child view controller, but several here told me that was likely to cause problems, being a circular reference. That setup worked, though; now I'm not sure how to accomplish the same thing "the right way." As usual, thanks in advance for your help.

  • C program - Seg fault, cause of

    - by resonant_fractal
    Running this gives me a seg fault (gcc filename.c -lm), when i enter 6 (int) as a value. Please help me get my head around this. The intended functionality has not yet been implemented, but I need to know why I'm headed into seg faults already. Thanks! #include<stdio.h> #include<math.h> int main (void) { int l = 5; int n, i, tmp, index; char * s[] = {"Sheldon", "Leonard", "Penny", "Raj", "Howard"}; scanf("%d", &n); //Solve Sigma(Ai*2^(i-1)) = (n - k)/l if (n/l <= 1) printf("%s\n", s[n-1]); else { tmp = n; for (i = 1;;) { tmp = tmp - (l * pow(2,i-1)); if (tmp <= 5) { // printf("Breaking\n"); break; } ++i; } printf("Last index = %d\n", i); // ***NOTE*** //Value lies in next array, therefore ++i; index = tmp + pow(2, n-1); printf("%d\n", index); } return 0; }

  • Twitter friends timeline not returning full history

    - by twofivesevenzero
    I am using twitter4J to get a user's friends timeline, but it is not returning the full available history. I know there are pagination limits (200 per request and 3200 total as per http://bit.ly/ck8ysq) and I am well within those. I make a request like so: private static final int MAX_COUNT = 200; private List<Status> getAllStatuses(long sinceID) throws TwitterException { Twitter twitter = new Twitter(username, password); List<Status> friendsTimelineList = new ArrayList<Status>(); List<Status> tempList; int page = 0; do { page++; tempList = twitter.getFriendsTimeline( new Paging(page, MAX_COUNT, sinceID)); if(tempList == null ) break; friendsTimelineList.addAll(tempList); } while(true); return friendsTimelineList; } This results in only 423 statuses being returned across 3 pages. Any idea why this might be happening?

  • Int - number too large. How to get program to fail?

    - by Dave
    Hi Problem: How do you get a program to fail if a number goes beyond the bounds of its type? This code below gives the wrong answer for sum of primes under 2 million as I'd used an int instead of a long. [TestMethod] public void CalculateTheSumOfPrimesBelow2million() { int result = PrimeTester.calculateTheSumOfPrimesBelow(2000000); // 2million Assert.AreEqual(1, result); // 1,179,908,154 .. this was what I got with an int... // correct answer was 142,913,828,922 with a long } public static class PrimeTester { public static int calculateTheSumOfPrimesBelow(int maxPrimeBelow) { // we know 2 is a prime number int sumOfPrimes = 2; int currentNumberBeingTested = 3; while (currentNumberBeingTested < maxPrimeBelow) { double squareRootOfNumberBeingTested = (double)Math.Sqrt(currentNumberBeingTested); bool isPrime = true; for (int i = 2; i <= squareRootOfNumberBeingTested; i++) { if (currentNumberBeingTested % i == 0) { isPrime = false; break; } } if (isPrime) sumOfPrimes += currentNumberBeingTested; currentNumberBeingTested += 2; // as we don't want to test even numbers } return sumOfPrimes; } }

  • Very simple code for number search gives me infinite loop

    - by Joshua
    Hello, I am a newbie Computer Science high school student and I have trouble with a small snippet of code. Basically, my code should perform a basic CLI search in an array of integers. However, what happens is I get what appears to be an infinite loop (BlueJ, the compiler I'm using, gets stuck and I have to reset the machine). I have set break points but I still don't quite get the problem...(I don't even understand most of the things that it tells me) Here's the offending code (assume that "ArrayUtil" works, because it does): import java.util.Scanner; public class intSearch { public static void main(String[] args) { search(); } public static void search() { int[] randomArray = ArrayUtil.randomIntArray(20, 100); Scanner searchInput = new Scanner(System.in); int searchInt = searchInput.nextInt(); if (findNumber(randomArray, searchInt) == -1) { System.out.println("Error"); }else System.out.println("Searched Number: " + findNumber(randomArray, searchInt)); } private static int findNumber(int[] searchedArray, int searchTerm) { for (int i = 0; searchedArray[i] == searchTerm && i < searchedArray.length; i++) { return i; } return -1; } } This has been bugging me for some time now...please help me identify the problem!

  • Render different view depending on the type of the data

    - by Miau
    Hi there So lets suppose we have an action in a controller that looks a bit like this: public ViewResult SomeAction(int id) { var data = _someService.GetData(id); ... //create new view model based on the data here return View(viewModel); } What I m trying to figure out is the best way to render a diferent view based on the type fo the data. the "_someService.GetData method returns an data that knows its out type (ie not only you can do typeof(data) but also you can do data.DataType and you ll get an enum value so I could achieve what I m trying to do doing something kinda like this public ViewResult SomeAction(int id) { var data = _someService.GetData(id); //I m mapping fields to the viewModel here var viewModel = GetViewModel(data); swtich(data.DataType) case DataType.TypeOne: return View("TypeOne", viewModel); break; ... } But this does not seem to be the nicest way, (I dont event know if it would work) Is this the way to go? Should I use some sort of RenderPartial Aproach? after all , waht will change in the view is mostly the order of the data (ie the rest of the view would be quite similar) Cheers

  • How to refactor models without breaking WPF views?

    - by Tim Murphy
    I've just started learning WPF and like the power of databinding it presents; that is ignoring the complexity and confusion for a noob. My concern is how do you safely refactor your models/viewmodels without breaking the views that use them? Take the following snippet of a view for example: <Grid> <ListView ItemsSource="{Binding Contacts}"> <ListView.View> <GridView> <GridViewColumn Header="First Name" DisplayMemberBinding="{Binding Path=FirstName}"/> <GridViewColumn Header="Last Name" DisplayMemberBinding="{Binding Path=FirstName}"/> <GridViewColumn Header="DOB" DisplayMemberBinding="{Binding Path=DateOfBirth}"/> <GridViewColumn Header="# Pets" DisplayMemberBinding="{Binding Path=NumberOfPets}"/> <GridViewColumn Header="Male" DisplayMemberBinding="{Binding Path=IsMale}"/> </GridView> </ListView.View> </ListView> </Grid> The list is bound to the Contacts property, IList(Of Contact), of the windows DataSource and each of the properties for a Contact is bound to a GridViewColumn. Now if I change the name of the NumberOfPets property in the Contact model to PetCount the view will break. How do I prevent the view breaking?

  • localhost + staging + production environments?

    - by Kentor
    Hello, I have a website say www.livesite.com which is currently running. I have been developing a new version of the website on my local machine with http://localhost and then committing my changes with svn to www.testsite.com where I would test the site on the livesite.com server but under another domain (its the same environment as the live site but under a different domain). Now I am ready to release the new version to livesite.com. Doing it the first time is easy, I could just copy & paste everything from testsite.com to livesite.com (not sure its the best way to do it). I want to keep testsite.com as a testing site where I would push updates, test them and once satisfied move to livesite.com but I am not sure how to do that after the new site is launched.. I don't think copy pasting the whole directory is the right way of doing it and it will break the operations of current users on the livesite.com. I also want to keep my svn history on testsite.com. What is the correct way of doing this with SVN ? Thank you so much!

  • pointer, malloc and char in C

    - by user2534078
    im trying to copy a const char array to some place in the memory and point to it . lets say im defining this var under the main prog : char *p = NULL; and sending it to a function with a string : myFunc(&p, "Hello"); now i want that at the end of this function the pointer will point to the letter H but if i puts() it, it will print Hello . here is what i tried to do : void myFunc(char** ptr , const char strng[] ) { *ptr=(char *) malloc(sizeof(strng)); char * tmp=*ptr; int i=0; while (1) { *ptr[i]=strng[i]; if (strng[i]=='\0') break; i++; } *ptr=tmp; } i know its a rubbish now, but i would like to understand how to do it right, my idea was to allocate the needed memory, copy a char and move forward with the pointer, etc.. also i tried to make the ptr argument byreferenec (like &ptr) but with no success due to a problem with the lvalue and rvalue . the only thing is changeable for me is the function, and i would like not to use strings, but chars as this is and exercise . thanks for any help in advance.

  • How to split this string and identify first sentence after last '*'?

    - by DaveDev
    I have to get a quick demo for a client, so this is a bit hacky. Please don't flame me too much! :-) I'm getting a string similar to the following back from the database: The object of the following is to do: * blah 1 * blah 2 * blah 3 * blah 4. Some more extremely uninteresting text. Followed by yet another sentence full of extrememly uninteresting text. Thankfully this is the last sentence. I need to format this so that each * represents a bullet point, and the sentence after the last * goes onto a new line, ideally as follows: The object of the following is to do: blah 1 (StackOverflow wants to add bullet points here, but I just need '*') blah 2 blah 3 blah 4. Some more extremely uninteresting text. Followed by yet another sentence full of extrememly uninteresting text. Thankfully this is the last sentence. It's easy enough to split the string by the * character and replace that with <br /> *. I'm using the following for that: string description = GetDescription(); description = description.Replace("*", "<br />*"); // it's going onto a web page. but the result this gives me is: The object of the following is to do: blah 1 blah 2 blah 3 blah 4. Some more extremely uninteresting text. Followed by yet another sentence full of extrememly uninteresting text. Thankfully this is the last sentence. I'm having a bit of difficulty identifying the fist sentence after the last '*' so I can put a break there too. Can somebody show me how to do this?

  • Clear button at uisearchbar not working at all

    - by kevin.ng
    I created a search bar programmatically and added to my view using the codes below: - (void)viewDidLoad { searchBar = [[UISearchBar alloc] initWithFrame:CGRectMake(xPositionForSearchBar, yPositionForSearchBar, widthForSearchBar, heightForSearchBar)]; UIView *bg = [[searchBar subviews] objectAtIndex:0]; searchBar.delegate = self; searchBar.placeholder = @"Search record"; for(UIView *view in searchBar.subviews){ if([view isKindOfClass:[UITextField class]]){ UITextField *tf = (UITextField *)view; tf.delegate = self; break; } } [bg removeFromSuperview]; [self.view addSubview: searchBar]; } The code is implemented with UISearchBarDelegate and UITextFieldDelegate. I have tried using - (void)searchBarCancelButtonClicked:(UISearchBar *)aSearchBar { NSLog(@"cancel clicked"); searchBar.text = @""; [aSearchBar resignFirstResponder]; } - (BOOL)textFieldShouldClear:(UITextField *)textField { NSLog(@"clear"); [self performSelector:@selector(searchBarCancelButtonClicked:) withObject:searchBar afterDelay: 0.1]; return YES; } and yet, the text inside the searchBar is not cleared at all when i click on the "clear button" - a circle with a "X" inside. The clear button works when I implemented it in IB. Wonder why? Kindly advice, many thanks.

  • What's the deal with the hidden Throw when catching a ThreadAbortException?

    - by priehl
    I'm going through a book of general c# development, and I've come to the thread abort section. The book says something along the lines that when you call Thread.Abort() on another thread, that thread will throw a ThreadAbortException, and even if you tried to supress it it would automatically rethrow it, unless you did some bs that's generally frowned upon. Here's the simple example offered. using System; using System.Threading; public class EntryPoint { private static void ThreadFunc() { ulong counter = 0; while (true) { try { Console.WriteLine("{0}", counter++); } catch (ThreadAbortException) { // Attempt to swallow the exception and continue. Console.WriteLine("Abort!"); } } } static void Main() { try { Thread newThread = new Thread(new ThreadStart(EntryPoint.ThreadFunc)); newThread.Start(); Thread.Sleep(2000); // Abort the thread. newThread.Abort(); // Wait for thread to finish. newThread.Join(); } catch (Exception e) { Console.WriteLine(e.ToString()); } } } The book says: When your thread finishes processing the abort exception, the runtime implicitly rethrows it at the end of your exception handler. It’s the same as if you had rethrown the exception yourself. Therefore, any outer exception handlers or finally blocks will still execute normally. In the example, the call to Join won’t be waiting forever as initially expected. So i wrapped a try catch around the Thread.Abort() call and set a break point, expecting it to hit this, considering the text says "any outer exception handlers or finally blocks will still execute normally". BUT IT DOES NOT. I'm racking my brain to figure out why. Anyone have any thoughts on why this isn't the case? Is the book wrong? Thanks in advance.

  • Can't add or remove object from NSMutableSet

    - by Dan Ray
    Check it: - (IBAction)toggleFavorite { DataManager *data = [DataManager sharedDataManager]; NSMutableSet *favorites = data.favorites; if (thisEvent.isFavorite == YES) { NSLog(@"Toggling off"); thisEvent.isFavorite = NO; [favorites removeObject:thisEvent.guid]; [favoriteIcon setImage:[UIImage imageNamed:@"notFavorite.png"] forState:UIControlStateNormal]; } else { NSLog(@"Toggling on, adding %@", thisEvent.guid); thisEvent.isFavorite = YES; [favorites addObject:thisEvent.guid]; [favoriteIcon setImage:[UIImage imageNamed:@"isFavorite.png"] forState:UIControlStateNormal]; } NSLog(@"favorites array now contains %d members", [favorites count]); } This is fired from a custom UIButton. The UI part works great--toggles the image used for the button, and I can see from other stuff that the thisEvent.isFavorite BOOL is toggling happily. I can also see in the debugger that I'm getting my DataManager singleton. But here's my NSLog: 2010-05-13 08:24:32.946 MyApp[924:207] Toggling on, adding 05db685f65e2 2010-05-13 08:24:32.947 MyApp[924:207] favorites array now contains 0 members 2010-05-13 08:24:33.666 MyApp[924:207] Toggling off 2010-05-13 08:24:33.666 MyApp[924:207] favorites array now contains 0 members 2010-05-13 08:24:34.060 MyApp[924:207] Toggling on, adding 05db685f65e2 2010-05-13 08:24:34.061 MyApp[924:207] favorites array now contains 0 members 2010-05-13 08:24:34.296 MyApp[924:207] Toggling off 2010-05-13 08:24:34.297 MyApp[924:207] favorites array now contains 0 members Worst part is, this USED to work, and I don't know what I did to break it.

  • facebook comments ajax

    - by Shunsho
    I have a function that load a jquery ui accordion (differents accordions based on different id) When I click on the tab titled "Facebook Comments" I do: $("#myaccordion").bind('accordionchange', function(event, ui) { id = $("#myaccordion").data('id'); switch (ui.newHeader.text()) { case "Facebook Comments": displayFb(id); break; } }); The "displayFB" function is: function displayFb(id){ $.get('/fbcomments/' + id, function(data) { $("#facecomm").append(data); }); } Where www.myweb.com/fbcomments/id is: <div id="fb-root"></div> <script>(function(d, s, id) { var js, fjs = d.getElementsByTagName(s)[0]; if (d.getElementById(id)) return; js = d.createElement(s); js.id = id; js.src = "//connect.facebook.net/es_ES/all.js#xfbml=1"; fjs.parentNode.insertBefore(js, fjs); }(document, 'script', 'facebook-jssdk'));</script> <div class="fb-comments" data-href="<?php echo '/fbcomments/'.$id ?>" data-num-posts="10" data-width="220"></div> When I load the homepage, then choose an accordion, then open a Facebook Comments, it works perfect. If I reload the page and choose another accordion, work perfect again. The problem is when I choose another accordion or the same again without reload the whole page. The accordions loads very well, all the data on them (some tabs of images, text, videos, etc), but the facebook comments don't appear. I tried: loading the #fb-root and facebook comment <script> on the main layout....doesn't work. adding FB.XFBML.parse(); into displayFB function....doesn't work adding FB.XFBML.parse(); into a $(document).ready(function(){} ...doesn't work.

  • In Javascript, what's better than try/catch for exiting an outer scope?

    - by gruseom
    In Javascript, I sometimes want to return a value from a scope that isn't the current function. It might be a block of code within the function, or it might be an enclosing function as in the following example, which uses a local function to recursively search for something. As soon as it finds a solution, the search is done and the whole thing should just return. Unfortunately, I can't think of a simpler way to do this than by hacking try/catch for the purpose: function solve(searchSpace) { var search = function (stuff) { solution = isItSolved(stuff); if (solution) { throw solution; } else { search(narrowThisWay(stuff)); search(narrowThatWay(stuff)); }; }; try { return search(searchSpace); } catch (solution) { return solution; }; }; I realize one could assign the solution to a local variable and then check it before making another recursive call, but my question is specifically about transfer of control. Is there a better way than the above? Perhaps involving label/break?

  • How can I use multi-threading with a "for" or "foreach" loop?

    - by saafh
    I am trying to run the for loop in a separate thread so that the UI should be responsive and the progress bar is visible. The problem is that I don't know how to do that :). In this code, the process starts in a separate thread, but the next part of the code is executed at the same time. The messageBox is displayed and the results are never returned (e.g. the listbox's selected index property is never set). It doesn't work even if I use, "taskEx.delay()". TaskEx.Run(() => { for (int i = 0; i < sResults.Count(); i++) { if (sResults.ElementAt(i).DisplayIndexForSearchListBox.Trim().Contains(ayaStr)) { lstGoto.SelectedIndex = i; lstGoto_SelectionChanged(lstReadingSearchResults, null); IsIndexMatched = true; break; } } }); //TaskEx.delay(1000); if (IsIndexMatched == true) stkPanelGoto.Visibility = Visibility.Collapsed; else //the index didn't match { MessagePrompt.ShowMessage("The test'" + ayaStr + "' does not exist.", "Warning!"); } Could anyone please tell me how can I use multi-threading with a "for" or "foreach" loop?

  • CakePHP – 2 controllers, 1 form

    - by user1327
    I need to create a review form. I have 2 models and 2 controllers – Products and Reviews with 'Products' hasMany 'Reviews' relationship, the review form will be displayed on the current product page (Products controller, 'view' action), and this form will be use another controller (Reviews). Also I need validation with validation errors being displayed for this form. In my Products controller view.ctp I have: // product page stuff... echo $this->Form->create($model = 'Review', array('url' => '/reviews/add')); echo $this->Form->input('name', array('label' => 'Your name:')); echo $this->Form->input('email', array('label' => 'Your e-mail:')); echo $this->Form->input('message', array('rows' => '6', 'label' => 'Your message:')); echo $this->Form->end('Send'); echo $this->Session->flash(); ReviewsController - add: public function add() { if ($this->request->is('post')) { $this->Review->save($this->request->data); $this->redirect(array('controller' => 'products', 'action' => 'view', $this->request->data['Review']['product_id'], '#' => 'reviews')); } } Somehow this horrible code works.. in part. Review saves, but I don't get validation errors, and I can't add 'if ($this->Review->save($this->request->data);) { //... } because it will break this action (missed view error). My question is how to properly deal with this situation to achieve functionality that I need? Should I use elements with request action or I should move adding reviews to the ProductsController?

  • How to "pin" C++/CLI pointers

    I am wrapping up a class which reading a custom binary data file and makes the data available to a .net/c# class However a couple of lines down the code, i start getting the memory access violation error which i believe is due to the GC moving memory around, the class is managed Here's the code if ( ! reader.OpenFile(...) ) return ; foreach(string fieldName in fields) { int colIndex = reader.GetColIndex( fieldName ); int colType = reader.GetColType( colIndex ); // error is raised here on 2nd iteration } for ( int r = 0 ; r < reader.NumFields(); r++ ) { foreach(string fieldName in fields) { int colIndex = reader.GetColIndex( fieldName ); int colType = reader.GetColType( colIndex ); // error is raised here on 2nd iteration switch ( colType ) { case 0 : // INT processField( r, fieldName, reader.GetInt(r,colIndex) ); break ; .... } } } .... i've looked at interior_ptr, pin_ptr but they give an error c3160 cannot be in a managed class Any workaround ?

  • C++ Macro Arithmetric

    - by anon
    I have to do with Macros (it's macros calling macros; so templates are out of the question). Here's what I want: foo(3, a, b1, c1) --> foo1(a, b1, c1); foo(5, a, b1, c1, b2, c2) -> foo2(a, b1, c1, b2, c2); foo(7, a, b1, c1, b2, c2, b3, c3) -> foo3(a, b1, c1, b2, c2, b3, c3); So basically, what I want is to be able to execute the "function" n - (n-1)/2 at macro expansion time. Is this possible? Thanks! [PS, if you dislike my questions; I support your right to downvote; my worst question so far is only -17, so maybe we can break that record; however, please let me know why my question is technically invalid.] Thanks EDIT: Foo takes a variable # of arguments, of the form: foo(N, a1, b1, a2, b2, ... a_N, b_N) -> foo##N(a1, b1, a2, b2, ... a_N, b_N);

  • Handling a mix of server side code and html in a resource file?

    - by Brandon
    I'm trying to convert an ASP.NET web application to use resource files. I haven't used resource files before, so I'm just toying around with them and was wondering if this is possible. I have a message that returns from a search when no results are found, that prompts the user to return to the home page. A lot of these pages have methods to determine what is the proper page to send the user to, so there are many sections with markup similar to this: Sorry, but we could not find an item matching your search criteria. Please adjust your search criteria or <a href="<%= SomeMethodToDetermineUri() %>">return to (SomePage)</a>. So basically, some type of message, followed by a link or a list of links. Getting the message part works fine, it's the server side code to generate links thats the problem. What is the best way to put that into a resource file? It is able to recognize the html link part just fine, but the server side code gets inserted as plain text. Is the only way to break it into 2 resources? (Which seems messy) <%= Resources.Master.NoSearchResultsFound %> <a href="<%= SomeMethodToDetermineUri() %>"> <%= Resources.Master.NoSearchResultsFoundReturnLinkText %> </a>. Or is there a way to get the page to evaluate the server code?

  • Reference problem when returning an object from array in PHP

    - by avastreg
    I've a reference problem; the example should be more descriptive than me :P I have a class that has an array of objects and retrieve them through a key (string), like an associative array: class Collection { public $elements; function __construct() { $this->elements = array(); } public function get_element($key) { foreach($this->elements as $element) { if ($element->key == $key) { return $element; break; } } return null; } public function add_element ($element) { $this->elements[] = $element; } } Then i have an object (generic), with a key and some variables: class Element { public $key; public $another_var; public function __construct($key) { $this->key = $key; $this->another_var = "default"; } } Now, i create my collection: $collection = new Collection(); $collection->add_element(new Element("test1")); $collection->add_element(new Element("test2")); And then i try to change variable of an element contained in my "array": $element = $collection->get_element("test1"); $element->another_var = "random_string"; echo $collection->get_element("test1")->another_var; Ok, the output is random_string so i know that my object is passed to $element in reference mode. But if i do, instead: $element = $collection-get_element("test1"); $element = null; //or $element = new GenericObject(); $element-another_var = "bla"; echo $collection-get_element("test1")-another_var; the output is default like if it lost the reference. So, what's wrong? I have got the references to the variables of the element and not to the element itself? Any ideas?

  • Generating random thumbnails with PHP+FFMPEG

    - by MrGhost
    I am trying to generate thumbnails from movies using FFMPEG and the FFMPEG-PHP extension. My script works OK however takes 20 minutes just to generate 5-10 thumbnails! The script works by generating random numbers which are used as frame numbers later. All numbers generated are within the movies frame count. Can you work out why this script is taking 20 mins to finish? <?php //Dont' timeout set_time_limit(0); //Load the file (This can be any file - still takes ages) $mov = new ffmpeg_movie('1486460.mp4'); //Get the total frames within the movie $total_frames = $mov->getFrameCount(); //Loop 5 times to generate random frame times for ($i = 1; $i <= 5; ) { // Generate a number within 200 and the total number of frames. $frame = mt_rand(200,$total_frames); $getframe = $mov->getFrame($frame); // Check if the frame exists within the movie // If it does, place the frame number inside an array and break the current loop if($getframe){ $frames[$frame] = $getframe ; $i++; } } //For each frame found generate a thumbnail foreach ($frames as $key => $getframe) { $gd_image = $getframe->toGDImage(); imagejpeg($gd_image, "images/shot_".$key.'.jpeg'); imagedestroy($gd_image); echo $key.'<br/>'; } ?> The script SHOULD be generating frame numbers which are valid? Anything within START - END should be valid frame numbers? Yet the loop takes ages!
