• Can I use a UINavigationController as the detail view of a UISplitViewController?

  - by B Sweigard

  I'm running into a problem with an iPad app where I would like to have UINavigationControllers in both of the views within a UISplitView. I've looked through other similar questions here, but most link to a tutorial online that doesn't completely solve the problem. Here's a 2-minute walkthrough to re-create the problem I'm having: Create a New Project in XCode, starting from the Split View-based Application template. Add the following NSLog statement as the first line within the DetailViewController's willHideViewController method: NSLog(@"toolbar: %@", toolbar); If you run the application now, the log will show that the DetailViewController's toolbar is alive and well. Now... Open MainWindow.xib and expand the SplitViewController. Drag a Navigation Controller from the library on top of the DetailViewController. Expand the new Navigation Controller and change the class of the UIViewController within to a DetailViewController. Ctrl-drag from the SplitViewController to the DetailViewController and assign it as the delegate. Save MainWindow.xib and run the app again. At this point, the detail view has a navigation bar and an empty toolbar. If you view the logs, you should find that the toolbar is null. Why is this? Am I missing some sort of connection in Interface Builder? Is the navigation bar the problem for some reason? Unlike the tutorial at http://www.cimgf.com/2010/05/24/fixing-the-uisplitviewcontroller-template/, I would like to keep both the navigation bar and the toolbar (preferably with the toolbar at the top when in portrait and not visible when in landscape), so that I still have a functional "Back" button when the iPad is in portrait orientation. Does anyone have any suggestions for fixing this problem? An example project with this sort of set-up would be ideal.

• iphone navigation

  - by Rona

  function handleClickEvent(event) { var linkFrom = $(event.target); if (typeof linkFrom.attr("href") == 'undefined') { linkFrom = $(event.target).parent(); } var targetPage = linkFrom.attr("href"); if (linkFrom.hasClass('submit')) { handleSubmitEvent(event); // if we want to stop processing: return false; } if (linkFrom.hasClass('backbutton')) { targetPage = historyStack.pop(); if (historyStack.length == 0) { lastPage = "index.html"; } } else { historyStack.push(lastPage); } lastPage = targetPage; $(event.target).css({ 'background-color': '#194fdb', 'color': '#ffffff' }); loadingWindowON(); // Add new unique div prevPageId = "page" + pageIdCounter; pageIdCounter = parseInt(pageIdCounter) + 1 nextPageId = "page" + pageIdCounter; nextPageDiv = "<div id='" + nextPageId + "' class='nextpage' /></div>"; $("body").append(nextPageDiv); if (linkFrom.attr("target") != "_blank") { event.preventDefault(); document.getElementById(nextPageId).addEventListener('webkitAnimationEnd', function () { // remove prev div element = document.getElementById(prevPageId); if (element) { element.parentNode.removeChild(element); } // set next div as current document.getElementById(nextPageId).className = 'currentpage'; }, false); document.getElementById(nextPageId).className += ' slideleftIn'; document.getElementById(prevPageId).className += ' slideleftOut'; loadContent(targetPage, nextPageId); } I use this javascript with a twitter app I had to do and when I click a button, instead of sliding the new page from the side it adds it to the existing page at the bottom. It works fine when i open it on my computer using google chrome but when I try to open it with my iphone it doesn't work. Any ideas?

• Validation Logic

  - by user2961971

  I am trying to create some validation for a form I have. There are two text boxes and two radio buttons on the form. My logic for this validation I know is a little rusty at the moment so any suggestions would be great. Here is the code for what I have so far: Keep in mind that the int errors is a public variable in the class Start Button code: private void btnStart_Click(object sender, EventArgs e) { errors = validateForm(); //Here I want the user to be able to fix any errors where I am little stuck on that logic at the moment //validate the form while (errors > 0) { validateForm(); errors = validateForm(); } } ValidateForm Method: private int validateForm() { errors = 0; //check the form if there are any unentered values if (txtDest.Text == "") { errors++; } if (txtExt.Text == "") { errors++; } if (validateRadioBtns() == true) { errors++; } return errors; } ValidateRadioBtns Method: private Boolean validateRadioBtns() { //flag - false: selected, true: none selected Boolean blnFlag = false; //both of the radio buttons are unchecked if (radAll.Checked == false && radOther.Checked == false) { blnFlag = true; } //check if there is a value entered in the text box if other is checked else if(radOther.Checked == true && txtExt.Text == "") { blnFlag = true; } return blnFlag; } Overall I feel like this can somehow be more stream lined which I am fairly stuck on. Also, I am stuck on how to ensure the user can return to the form, fix the errors, and then validate again to ensure said errors are fixed. Any suggestions would be greatly appreciated since I know this is such a nooby question.

• interface abstract in php real world scenario

  - by jason

  The goal is to learn whether to use abstract or interface or both... I'm designing a program which allows a user to de-duplicate all images but in the process rather then I just build classes I'd like to build a set of libraries that will allow me to re-use the code for other possible future purposes. In doing so I would like to learn interface vs abstract and was hoping someone could give me input into using either. Here is what the current program will do: recursive scan directory for all files determine file type is image type compare md5 checksum against all other files found and only keep the ones which are not duplicates Store total duplicates found at the end and display size taken up Copy files that are not duplicates into folder by date example Year, Month folder with filename is file creation date. While I could just create a bunch of classes I'd like to start learning more on interfaces and abstraction in php. So if I take the scan directory class as the first example I have several methods... ScanForFiles($path) FindMD5Checksum() FindAllImageTypes() getFileList() The scanForFiles could be public to allow anyone to access it and it stores in an object the entire directory list of files found and many details about them. example extension, size, filename, path, etc... The FindMD5Checksum runs against the fileList object created from scanForFiles and adds the md5 if needed. The FindAllImageTypes runs against the fileList object as well and adds if they are image types. The findmd5checksum and findallimagetypes are optionally run methods because the user might not intend to run these all the time or at all. The getFileList returns the fileList object itself. While I have a working copy I've revamped it a few times trying to figure out whether I need to go with an interface or abstract or both. I'd like to know how an expert OO developer would design it and why?

• Mystery: How does Google do cross-domain iframe communication?

  - by Shraga

  Hi everyone, When you host Googles web search element on a page, a div is created which incorporates an iframe which points to a Google adsense ads page. However, if there are no ads for the specific query, Google somehow changes the class on YOUR domain to render the div (and iframe) invisible. They are NOT using postMessage, as it also works in IE7. They are also not using the fragment identifier method, as no hash appears in the url. So how do they do it? To check what I'm saying just put the following into a regular html page: <!-- Google Custom Search Element --> <div id="cse" style="width:100%;">Loading</div> <script src="http://www.google.com/jsapi" type="text/javascript"></script> <script type="text/javascript"> google.load('search', '1'); google.setOnLoadCallback(function(){ new google.search.CustomSearchControl().draw('cse'); }, true); </script> and then do a search for "cars" (or anything else that will definitely have ads) and then for "wzxv", which has no ads...

• Variable Scoping in a method and its persistence in C++

  - by de costo

  Consider the following public method that adds an integer variable to a vector of ints(private member) in a class in C++. KoolMethod() { int x; x = 10; KoolList.Add(x); } Vector<int>KoolList; But is this a valid addition to a vector ??? Upon calling the method, it creates a local variable. The scope of this local variable ends the moment the execution control leaves the method. And since this local variable is allocated on a stack(on the method call), any member of KoolList points to an invalid memory location in deallocated stack which may or may not contain the expected value of x. Is this an accurate description of above mechanism ?? Is there a need for creating an int in heap storage using "new" operator everytime a value needs to be added to the vector like described below ????: KoolMethod() { int *x = new int(); *x = 10; KoolList.Add(x); } Vector<int*>KoolList;

• math.Random isn't working right

  - by RandomlyKnighted

  I'm trying to simulate a coin flip using the code below. public class Coin { public static double result; int[] count = new count[2]; public static void flip() { result = Math.random(); } public static boolean isHeads() { if (result == 0.0) { count[0]++; return false; } else { count[1]++; return true; } } public static void main(String[] args) { flip(); isHeads(); System.out.println(count[0]); System.out.println(count[1]); } } For some reason Eclipse says that the import java.util.Random; is never used even though I'm clearly using it. I didn't put my for loop into the code above but it loops n number of times and then outputs the result. No matter how many times it loops it always returns that the result is greater than 0.0 which can't be right. Am I calling Math.random incorrectly?

• Moq basic questions

  - by devoured elysium

  I made the following test for my class: var mock = new Mock<IRandomNumberGenerator>(); mock.Setup(framework => framework.Generate(0, 50)) .Returns(7.0); var rnac = new RandomNumberAverageCounter(mock.Object, 1, 100); rnac.Run(); double result = rnac.GetAverage(); Assert.AreEqual(result, 7.0, 0.1); The problem here was that I changed my mind about what range of values Generate(int min, int max) would use. So in Mock.Setup() I defined the range as from 0 to 50 while later I actually called the Generate() method with a range from 1 to 100. I ran the test and it failed. I know that that is what it's supposed to happen but I was left wondering if isn't there a way to launch an exception or throw in a message when trying to run the method with wrong params. Also, if I want to run this Generate() method 10 times with different values (let's say, from 1 to 10), will I have to make 10 mock setups or something, or is there a special method for it? The best I could think of is this (which isn't bad, I'm just asking if there is other better way): for (int i = 1; i < 10; ++i) { mock.Setup(framework => framework.Generate(1, 100)) .Returns((double)i); }

• JavaScript Fails to load content correctly on start

  - by Gaz_Edge

  I have inherited an image gallery constructed using javascript. I believe it uses a variation of JQuery, but it seems to have been heavily edited. The gallery loads the first image on page load. Each image has comments below them. There are forward and backward arrows that move between images. The problem I seem to have is that if there is a comment on image one, it is not loaded on page start, the only way to get it to display is to click forward to the next image, then click back to image one. The comment is then shown. All the comments are loaded into a script in the header under var sent_comments = [{COMMENTS}] The comment HTML code on loading is as follows; <div id="comments_container"> <div id="comments"> </div> </div> Once I have clicked to image two and then back to image one, the code is; <div id="comments_container"> <div id="comments"> SOME COMMENT </div> </div> Previous image button is: <a class="prev save_state" href="#"> <img src="/next.png?" alt="Next"> </a> Im new to javascript so not really sure what I will need to do to ensure the comment is loaded for the first image when the page loads. Code here: http://static.albumexposure.net/assets/presentation-9f47b054d96f9ec2459e89619a5fe9b4.js http://static.albumexposure.net/assets/presentations/book-699d82a2beb39df264e54c5d2578e0e4.js

• Basic SQL Query, I am newbie

  - by user3530547

  I just started my database and query class on Monday. We met on Monday and just went over the syllabus, and on Wednesday the network at school was down so we couldn't even do the power point lecture. Right now I am working on my first homework assignment and I am almost finished but I am having trouble on one question. Here is is... Write a SELECT statement that returns one column from the Customers table named FullName that joins the LastName and FirstName columns. Format the columns with the last name, a comma, a space, and the first name like this: Doe, John Sort the result set by last name in ascending sequence. Return only the contacts whose last name begins with letters from M to Z. Here is what I have so far... USE md0577283 SELECT FirstName,LastName FROM Customers ORDER BY LastName,FirstName My question is how do I format is Lastname, FirstName like the professor wants and how do I only select names M-Z? If someone could point me in the right direction I would greatly appreciate it. Thank you. PS With all do respect, I didn't ask for the answer I asked for a nudge in the right direction so why the down vote guys?

• jQuery - Cancel form submit (using "return false"?)?

  - by Nike

  Hey there. I'm running into a bit of trouble while trying to cancel the submit of a form. I've been following this tutorial (even though i'm not making a login script), and it seems to be working for him. Here's my form: <form action="index.php" method="post" name="pForm"> <textarea name="comment" onclick="if(this.value == 'skriv här...') this.value='';" onblur="if(this.value.length == 0) this.value='skriv här...';">skriv här...</textarea> <input class="submit" type="submit" value="Publicera!" name="submit" /> </form> And here's the jquery: $(document).ready(function() { $('form[name=pForm]').submit(function(){ return false; }); }); I've already imported jQuery in the header and i know it's working. My first thought was that it might be outdated, but it's actually "just" a year ago. So do anyone see what's wrong? Thanks in advance. EDIT: From what i've read the easiest and most appropriate way to abort the submit is to return false? But i can't seem to get it working. I've searched the forum and i've found several helpful threads but none of them actually works. I must be screwing something up.

• strange doctrine update problem

  - by larryzhao

  Hi, guys, I have a simple table like following: class SnookerCurrentInfo extends Doctrine_Record { public function setTableDefinition() { $this->hasColumn('current_frame_id', 'integer', 4, array('notnull' => 'false')); $this->hasColumn('current_player_id', 'integer', 4, array('notnull' => 'false')); $this->hasColumn('current_score1', 'integer', 4, array('notnull' => 'false')); $this->hasColumn('current_score2', 'integer', 4, array('notnull' => 'false')); } public function setUp(){ $this->setTableName('snooker_current_info'); } } and I would like to keep only one entry in this table. So every time the value is changed I read the entry with id = 1 out and change the object and execute save. like the following: $info = Doctrine::getTable('SnookerCurrentInfo')->find(1); $info->current_frame_id = $jsonInfo['current_frame_id']; $info->current_player_id = $jsonInfo['current_player_id']; $info->current_score1 = $jsonInfo['current_score1']; $info->current_score2 = $jsonInfo['current_score2']; $info->save(); but the strange thing is, I try to make it clear. Let's say at first, the entry is (30, 1, 1, 0) and I switch player, so update the entry to (30, 2, 1, 0). and I switch the player back again, so the entry should be updated to (30, 1, 1, 0), but this is not affected to the database!! In the database, the entry still remains as (30, 2, 1, 0)!!!! But if after (30, 2, 1, 0), I update the score to (30, 2, 1, 1) and then switch the player back (30, 1, 1, 1) then this is ok. What's that? How should I deal with it? Thanks for a lot helping, really urgent!!

• Fastest container or algorithm for unique reusable ids in C++

  - by gman

  I have a need for unique reusable ids. The user can choose his own ids or he can ask for a free one. The API is basically class IdManager { public: int AllocateId(); // Allocates an id void FreeId(int id); // Frees an id so it can be used again bool MarkAsUsed(int id); // Let's the user register an id. // returns false if the id was already used. }; Assume ids happen to start at 1 and progress, 2, 3, etc. This is not a requirement, just to help illustrate. IdManager mgr; mgr.MarkAsUsed(3); printf ("%d\n", mgr.AllocateId()); printf ("%d\n", mgr.AllocateId()); printf ("%d\n", mgr.AllocateId()); Would print 1 2 4 Because id 3 has already been declared used. What's the best container / algorithm to both remember which ids are used AND find a free id? If you want to know the a specific use case, OpenGL's glGenTextures, glBindTexture and glDeleteTextures are equivalent to AllocateId, MarkAsUsed and FreeId

• C# WPF Unable to control Textboxes

  I'm a beginner in coding into C#. While I'm launching a process I can't controls my textboxes. I found some answers on this forum but the explaination is a bit to difficult for me to implement it for my problem. I created a small program that will run a batch file to make a backup. While the backup is running I can't modify my textboxes, disabling buttons etc... I already saw that this is normal but I don't know how to implement the solutions. My last attempt was with Dispatcher.invoke as you can see below. public partial class MainWindow : Window { public MainWindow() { InitializeComponent(); tb_Status.Text = "Ready"; } public void status() { Dispatcher.Invoke(DispatcherPriority.Send, new Action( () => { tb_Status.Text = "The backup is running!"; } ) ); } public void process() { try { Process p = new Process(); p.StartInfo.WindowStyle = ProcessWindowStyle.Minimized; p.StartInfo.CreateNoWindow = true; p.StartInfo.UseShellExecute = false; p.StartInfo.RedirectStandardOutput = true; p.StartInfo.FileName = "Robocopy.bat"; p.Start(); string output = p.StandardOutput.ReadToEnd(); p.WaitForExit(); tb_Output.Text = File.ReadAllText("Backup\\log.txt"); } catch (Exception ex) { tb_Status.Text = ex.Message.ToString(); } } private void Bt_Start_Click(object sender, EventArgs e) { status(); Directory.CreateDirectory("Backup"); process(); tb_Status.Text = "The backup finished"; File.Delete("Backup\\log.txt"); } } } Any help is appreciated!

  Running Maven, Eclipse, and Weblogic, when I try to Run As Server onto my local server, I get this error: "Cannot find the declaration of element 'beans'. at mvc-dispatcher-servlet.xml" Then, when I go back into the xml, select all, copy, delete, and paste, error goes away and I'm able to run the web app just fine on the server. Can anyone explain why? <beans xmlns="http://www.springframework.org/schema/beans" xmlns:context="http://www.springframework.org/schema/context" xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd"> <context:component-scan base-package="src.srcc.sndao" /> <mvc:annotation-driven /> <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name="prefix"> <value>/WEB-INF/view/</value> </property> <property name="suffix"> <value>.jsp</value> </property> </bean> </beans>

• Looking for PyQt4 embeddable terminal widget

  - by redShadow

  I wrote an application that, among other things, launches some "backend" processes to do some stuff. These subprocesses are very likely to fail or have unexpected behavior since they have to operate in quite hard conditions, so I prefer to give full control over them to the operator. NOTE: I am running these processes using a subprocess module based class instead of QProcess to have some more control functionality over the running process. At the moment, I'm using a QPlainTextEdit widget to which I append standard output/error from the subprocess, plus some buttons to quickly send some common signals (INT, STOP, CONT, KILL, ..), but: In some cases it would be useful to send some input too. Although it could be done with a text input box, I would prefer using something more "professional" Of course, there is no direct way to interpret special control characters, such as color codes, cursor movement, etc.. I had to implement an auto-scroll management of the console, but it is not guaranteed 100% to work nicely (sometimes the scroll locking doesn't work as expected, etc.) So: does anyone know something I could use to accomplish these needs? I found qtermwidget but it seems more oriented on handling a shell process (and the Python bindings seems to let you run /bin/bash only) by itself than communicating with an already existing process I/O.

• XNA, C# - Check if a Vector2 path crosses another Vector2 path.

  - by Nick

  Hello all, I have an XNA question for those with more experience in these matters than myself (maths). Background: I have a game that implements a boundary class, this simply hosts 2 Vector2 objects, a start and an end point. The current implementation crudely handles collision detection by assuming boundaries are always vertical or horizontal, i.e. if start.x and end.x are the same check I am not trying to pass x etc. Ideally what I would like to implement is a method that accepts two Vector2 parameters. The first being a current location, the second being a requested location (where I would like to move it to assuming no objections). The method would also accept a boundary object. What the method should then do is tell me if I am going to cross the boundry in this move. this could be a bool or ideally something representing how far I can actually move. This empty method might explain better than I can in words. /// <summary> /// Checks the move. /// </summary> /// <param name="current">The current.</param> /// <param name="requested">The requested.</param> /// <param name="boundry">The boundry.</param> /// <returns></returns> public bool CheckMove(Vector2 current, Vector2 requested, Boundry boundry) { //return a bool that indicated if the suggested move will cross the boundry. return true; }
