• Jquery: Display element relative to another

  - by namtax

  Hi I am trying to display a drop down list using jquery everytime a user clicks on a particular formfield... At the moment the HTML is as stands // Form field to enter the time an event starts <div> <label for="eventTime"> Event Time </label> <input type = "text" name="eventTime" id="eventTime" class="time"> </label> </div> // Form field to enter the time an event finishes <div> <label for="eventEnd"> Event Ends</label> <input type = "text" name="eventEnds" id="eventEnds" class="time"> </label> </div> And the Jquery looks like so // Display Time Picker $('.time').click(function(){ var thisTime = $(this); var timePicker = '<ul class="timePicker">' timePicker += '<li>10.00am</li>' timePicker += '<li>11.00am</li>' timePicker += '<li>12.00am</li>' timePicker += '</ul>' $('.timePicker').hide().insertAfter(thisTime); //show the menu directly over the placeholder var pos = thisTime.offset(); $(".timePicker").attr({ top: pos.top left: pos.left }); $(".timePicker").show(); }); However, when I click on one the form fields with class time, the timePicker drop down appears, but it always appears in the same location, not next to the form field as I would like. Any ideas? Thanks

• JQuery Selector - Finding an img in a table

  - by CccTrash

  Cant seem to get the following to find the 'skull' button when the 'heart' button is clicked... Here is the JQuery... $(".voteup").click(function() { var id = $(this).attr("title"); var userID = $('[id$=HiddenFieldUserID]').val(); var ipAddress = $('[id$=HiddenFieldIPAddress]').val(); var skullButton = $(this).parent().siblings(".votedowntd").children("votedown"); registerUpVote("up", id, $(this), skullButton, userID, ipAddress); }); And the HTML... <table width="200px"> <td width="35px" class="votedowntd"> <img src='<%# (bool)Eval("skull") ? "images/skull.png" : "images/skull-bw.png" %>' alt="Vote Down" class="votedown" title='<%# Eval("entry.ID") %>' /> </td> <td width="130px" style="text-align: center;"> Num Votes Goes Here </td> <td width="35px" class="voteuptd"> <img src='<%# (bool)Eval("heart") ? "images/heart.png" : "images/heart-bw.png" %>' alt="Vote Up" class="voteup" title='<%# Eval("entry.ID") %>' /> </td> <tr> </tr> </table> So basically what I need to do is when one img is clicked, I need to find the other one. Why is what I have not working? Is there a better way to do this?

• Using clases in PHP to store function

  - by Artur

  Hello! I need some advise on my PHP code organisation. I need classes where I can store different functions, and I need access to those classes in different parts of my project. Making an object of this classes each time is too sadly, so I've found a two ways have to solve it. First is to use static methods, like class car { public static $wheels_count = 4; public static function change_wheels_count($new_count) { car::$wheels_count = $new_count; } } Second is to use singleton pattern: class Example { // Hold an instance of the class private static $instance; // The singleton method public static function singleton() { if (!isset(self::$instance)) { $c = __CLASS__; self::$instance = new $c; } return self::$instance; } } But author of the article about singletons said, that if I have too much singletons in my code I should reconstruct it. But I need a lot of such classes. Can anybody explain prons and cons of each way? Which is mostly used? Are there more beautiful ways?

• Using Sub-Types And Return Types in Scala to Process a Generic Object Into a Specific One

  - by pr1001

  I think this is about covariance but I'm weak on the topic... I have a generic Event class used for things like database persistance, let's say like this: class Event( subject: Long, verb: String, directobject: Option[Long], indirectobject: Option[Long], timestamp: Long) { def getSubject = subject def getVerb = verb def getDirectObject = directobject def getIndirectObject = indirectobject def getTimestamp = timestamp } However, I have lots of different event verbs and I want to use pattern matching and such with these different event types, so I will create some corresponding case classes: trait EventCC case class Login(user: Long, timestamp: Long) extends EventCC case class Follow( follower: Long, followee: Long, timestamp: Long ) extends EventCC Now, the question is, how can I easily convert generic Events to the specific case classes. This is my first stab at it: def event2CC[T <: EventCC](event: Event): T = event.getVerb match { case "login" => Login(event.getSubject, event.getTimestamp) case "follow" => Follow( event.getSubject, event.getDirectObject.getOrElse(0), event.getTimestamp ) // ... } Unfortunately, this is wrong. <console>:11: error: type mismatch; found : Login required: T case "login" => Login(event.getSubject, event.getTimestamp) ^ <console>:12: error: type mismatch; found : Follow required: T case "follow" => Follow(event.getSubject, event.getDirectObject.getOrElse(0), event.getTimestamp) Could someone with greater type-fu than me explain if, 1) if what I want to do is possible (or reasonable, for that matter), and 2) if so, how to fix event2CC. Thanks!

• loading custom view using loadNibNamed showing memory leaks

  - by user307550

  I have a number of custom table cells and views that I built using interface builder In interface builder, everything is set up similarly. There is a table cell and a couple other UILabels and a background image Object owner if the nib is NSObject Class for the table cell is the name of the class for my table cell Here is how I create the table cell in my code: SectionedSwitchTableCell *cell = nil; NSArray *nibs = [[NSBundle mainBundle] loadNibNamed:kSectionedSwitchTableCellIdentifier owner:owner options:nil]; for(id currentObject in nibs) { if([currentObject isKindOfClass:[SectionedSwitchTableCell class]]) { cell = (SectionedSwitchTableCell *)currentObject; break; } } return cell; For my custom table headers I have this NSArray *nibs = [[NSBundle mainBundle] loadNibNamed:@"CustomTableHeader" owner:self options:nil]; for(id currentObject in nibs) { if([currentObject isKindOfClass:[CustomTableHeader class]]) { return header } } In my .h and .m files for the custom view, I have IBOutlet, @property set up for everything except for the background image UIImageView. Everything that has the IBOutlet and @property are also @synthesized and released in the .m file. Leaks is showing that I have memory leaks with CALayer when I create these custom view objects. Am I doing something wrong here when I create these custom view objects? I'm kind of tearing my hair out trying to figure out where these leaks are coming from. As a side note, I have a UIImageView background image defined in these custom views but I didn't define properties and IBOutlets in my .h and .m files. Defining them doesn't make a difference when I run it through Leaks but just wanted to confirm if I'm doing the right thing. Any input would be super helpful. Thanks :)

• hadoop implementing a generic list writable

  - by Guruprasad Venkatesh

  I am working on building a map reduce pipeline of jobs(with one MR job's output feeding to another as input). The values being passed around are fairly complex, in that there are lists of different types and hash maps with values as lists. Hadoop api does not seem to have a ListWritable. Am trying to write a generic one, but it seems i can't instantiate a generic type in my readFields implementation, unless i pass in the class type itself: public class ListWritable<T extends Writable> implements Writable { private List<T> list; private Class<T> clazz; public ListWritable(Class<T> clazz) { this.clazz = clazz; list = new ArrayList<T>(); } @Override public void write(DataOutput out) throws IOException { out.writeInt(list.size()); for (T element : list) { element.write(out); } } @Override public void readFields(DataInput in) throws IOException{ int count = in.readInt(); this.list = new ArrayList<T>(); for (int i = 0; i < count; i++) { try { T obj = clazz.newInstance(); obj.readFields(in); list.add(obj); } catch (InstantiationException e) { e.printStackTrace(); } catch (IllegalAccessException e) { e.printStackTrace(); } } } } But hadoop requires all writables to have a no argument constructor to read the values back. Has anybody tried to do the same and solved this problem? TIA.

• Transfer data between C++ classes efficiently

  - by David

  Hi, Need help... I have 3 classes, Manager which holds 2 pointers. One to class A another to class B . A does not know about B and vise versa. A does some calculations and at the end it puts 3 floats into the clipboard. Next, B pulls from clipboard the 3 floats, and does it's own calculations. This loop is managed by the Manager and repeats many times (iteration after iteration). My problem: Now class A produces a vector of floats which class B needs. This vector can have more than 1000 values and I don't want to use the clipboard to transfer it to B as it will become time consumer, even bottleneck, since this behavior repeats step by step. Simple solution is that B will know A (set a pointer to A). Other one is to transfer a pointer to the vector via Manager But I'm looking for something different, more object oriented that won't break the existent separation between A and B Any ideas ? Many thanks David

• How to store some of the entity's values in another table using hibernate?

  - by nimcap

  Hi guys, is there a simple way to persist some of the fields in another class and table using hibernate. For example, I have a Person class with name, surname, email, address1, address2, city, country fields. I want my classes to be: public class Person { private String name; private String surname; private String email; private Address address; // .. } public class Address { private Person person; // to whom this belongs private String address1; private String address2; private String city; private Address country; // .. } and I want to store Address in another table. What is the best way to achieve this? Edit: I am using annotations. It does not have to be the way I described, I am looking for best practices. PS. If there is a way to make Address immutable (to use as a value object) that is even better, or maybe not because I thought everything from wrong perspective :)

• Is private members hacking a defined behaviour ?

  - by ereOn

  Hi, Lets say I have the following class: class BritneySpears { public: int getValue() { return m_value; }; private: int m_value; }; Which is an external library (that I can't change). I obviously can't change the value of m_value, only read it. Even subclassing BritneySpears won't work. What if I define the following class: class AshtonKutcher { public: int getValue() { return m_value; }; public: int m_value; }; And then do: BritneySpears b; // Here comes the ugly hack AshtonKutcher* a = reinterpret_cast<AshtonKutcher*>(&b); a->m_value = 17; // Print out the value std::cout << b.getValue() << std::endl; I know this is a bad practice. But just for curiosity: is this guaranted to work ? Is it a defined behaviour ? Bonus question: Have you ever had to use such an ugly hack ? Thanks !

• No resource type specified (at 'id' with value '@+id\st')

• Logback: What would cause DEBUG - WARN to append to file but NOT ERROR?

  - by Zombies

  I am running a Java program from Eclipe, and I am using the logback console plugin. I can see the ERROR level statements being appended to console (as well as all of the others). But for some reason my file, which is correctly recieving new DEBUG-WARN statements, is NOT recieving the ERROR level ones. Here is my logback.xml: <consolePlugin /> <appender name="FILE" class="ch.qos.logback.core.FileAppender"> <file>logs/main.log</file> <layout class="ch.qos.logback.classic.PatternLayout"> <Pattern>%date %level [%thread] %logger{10} [%file:%line] %msg%n</Pattern> </layout> </appender> <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender"> <layout class="ch.qos.logback.classic.PatternLayout"> <Pattern>%msg%n</Pattern> </layout> </appender> <logger name="WebsiteChecker"> <appender-ref ref="FILE" /> </logger> <root> <level value="debug" /> <!--<appender-ref ref="STDOUT" />--> <appender-ref ref="FILE" /> </root> </configuration>

• Duplicating custom nodes in JavaFX

  - by Elazar Leibovich

  As far as I understand, duplicating nodes in JavaFX should be done with the Duplicator.duplicate function. It works fine when duplicating nodes whose types are included in JavaFX library, for example def dup = Duplicator.duplicate(Rectangle{x:30 y:30 width:100 height:100}); dup.translateX = 10; insert dup into content; would insert a black rectangle to the scene. However if I define a new class in the following way: class MyRect extends Rectangle {} Or class MyRect extends CustomNode { override function create() {Rectangle{x:30 y:30 width:10 height:10}} } It gives me the following runtime error Type 'javafxapplication1.NumberGrid$MyRect' not found. Where of course javafxapplication1.NumberGrid are the package and file the MyRect class is in. This guy at Sun's forums had the same problem, but I don't see any answer in there. Or maybe I'm doing that the wrong way, and there's a better approach for duplicating custom nodes? update: Trying to duplicate Group worked, but trying to duplicate Stack yields the same error. According to the documentation, it's supposed to support all types supported in FXD including Node, but maybe it supports only some of Node's descendants?

• How to use generic (NSObject) controller with subviews of a UIViewController?

  - by wanderlust

  I have a UIViewController that is loading several subviews at different times based on user interaction. I originally built all of these subviews in code, with no nib files. Now I am moving to nib files with custom UIView subclasses. Some of these subviews display static data, and I am using loadNibNamed:owner:options: to load them into the view controller. Others contain controls that I need to access. I (sort of) understand the reasons Apple says to use one view controller per screen of content, using generic controller objects (NSObjects) to manage subsections of a screen. So I need a view controller, a generic controller, a view class and a nib. How do I put this all together? My working assumptions and subsequent questions: I will associate the view class with the nib in the 'class identity' drop down in IB. The view controller will coordinate overall screen interactions. When necessary, it will create an instance of the generic controller. Does the generic controller load the nib? How? Do I define the outlets and actions in that view class, or should they be in the generic controller? How do I pass messages between the view controller and the generic controller? If anyone can point me to some sample code using a controller in this way, it will go a long way to helping me understand. None of the books or stackoverflow posts I've read have quite hit the spot yet.

• non-copyable objects and value initialization: g++ vs msvc

  - by R Samuel Klatchko

  I'm seeing some different behavior between g++ and msvc around value initializing non-copyable objects. Consider a class that is non-copyable: class noncopyable_base { public: noncopyable_base() {} private: noncopyable_base(const noncopyable_base &); noncopyable_base &operator=(const noncopyable_base &); }; class noncopyable : private noncopyable_base { public: noncopyable() : x_(0) {} noncopyable(int x) : x_(x) {} private: int x_; }; and a template that uses value initialization so that the value will get a known value even when the type is POD: template <class T> void doit() { T t = T(); ... } and trying to use those together: doit<noncopyable>(); This works fine on msvc as of VC++ 9.0 but fails on every version of g++ I tested this with (including version 4.5.0) because the copy constructor is private. Two questions: Which behavior is standards compliant? Any suggestion of how to work around this in gcc (and to be clear, changing that to T t; is not an acceptable solution as this breaks POD types). P.S. I see the same problem with boost::noncopyable.

• NSArrayController not working with NSMutableDictionary for NSTableView

  - by Miraaj

  Hi all, I am trying to display content in NSTableView using NSMutableArrayController of NSMutableDictionary records. I followed steps written below: In application delegate class, I created an NSMutableArray object with name 'geniuses' and stored some NSMutableDictionary objects with keys: 'geniusName' and 'domain'. I took an NSArrayController object in IB, binded its controller content property to application delegate class, and set its model key path to 'geniuses'. In attribute inspector pane set mode as class and class name as NSMutableDictionary. Added keys: 'geniusName' and 'domain' to it. In IB I took a table view object. Binded its content property to array controller, controller key path set as arranged objects. Binded value property of its first column to array controller, controller key path set as arranged objects, model key path set as 'geniusName'. Binded value property of its second column to array controller, controller key path set as arranged objects, model key path set as 'geniusName'. After following these steps when I tried to build and run the project I found un-populated table view. You can find my code here. Can anyone suggest me where I may be wrong? Thanks, Miraaj

• ClassLoader exceptions being memoized

  - by Jim

  Hello, I am writing a classloader for a long-running server instance. If a user has not yet uploaded a class definition, I through a ClassNotFoundException; seems reasonable. The problem is this: There are three classes (C1, C2, and C3). C1 depends on C2, C2 depends on C3. C1 and C2 are resolvable, C3 isn't (yet). C1 is loaded. C1 subsequently performs an action that requires C2, so C2 is loaded. C2 subsequently performs an action that requires C3, so the classloader attempts to load C3, but can't resolve it, and an exception is thrown. Now C3 is added to the classpath, and the process is restarted (starting from the originally-loaded C1). The issue is, C2 seems to remember that C3 couldn't be loaded, and doesn't bother asking the classloader to find the class... it just re-throws the memoized exception. Clearly I can't reload C1 or C2 because other classes may have linked to them (as C1 has already linked to C2). I tried throwing different types of errors, hoping the class might not memoize them. Unfortunately, no such luck. Is there a way to prevent the loaded class from binding to the exception? That is, I want the classloader to be allowed to keep trying if it didn't succeed the first time. Thanks!

• Django Database design -- Is this a good stragety for overriding defaults

  - by rh0dium

  Hi SO's I have a question on good database design practices and I would like to leverage you guys for pointers. The project started out simple. Hey we have a bunch of questions we want answered for every project (no problem) Which turned into... Hey we have so many questions can we group them into sections (yup we can do that) Which lead into.. Can we weight these questions and I don't really want some of these questions for my project (Yes but we are getting difficult) And then I'm thinking they will want to have each section have it's own weight.. Requirements So there's the requirements - For n number of project Allow a admin member the ability select the questions for a project Allow the admin member to re-weigh or use the default weights for the questions Allow the admin member to re-weight the sections Allow team members to answer the questions. So here is what I came up with. Please feel free to comment and provide better examples models.py from django.db import models from django.contrib.sites.models import Site from django.conf import settings class Section(models.Model): """ This describes the various sections for a checklist: """ name = models.CharField(max_length=64) description = models.TextField() class Question(models.Model): """ This simply provides a simple way to list out the questions. """ question = models.CharField(max_length=255) answer_type = models.CharField(max_length=16) description = models.TextField() section = models.ForeignKey(Section) class ProjectQuestion(models.Model): """ These are the questions relevant to the project """ question = models.ForeignKey(Question) answer = models.CharField(max_length=255) required = models.BooleanField(default=True) weight = models.FloatField(default = XXX) class Project(models.Model): """ Here is where we want to gather our questions """ questions = models.ManyToManyField(ProjectQuestion) Immediate questions: - When I start a project - any ideas on how to "pre-populate" the questions (and ultimately the weights) for the project? - Is there a generally accepted method for doing this process that I am missing? Basically the idea that you refer to the questions overide your own default weight, and store the answer? - It appears that a good chuck of the work will be done in the views and that a lot of checking will need to occur there? Is that OK? Again - feel free to give me better strategies!! Thanks

• Display all the options if nothing is selected

• Join Query Not Working

  - by John

  Hello, I am using three MySQl tables: comment commentid loginid submissionid comment datecommented login loginid username password email actcode disabled activated created points submission submissionid loginid title url displayurl datesubmitted In these three tables, the "loginid" correspond. I would like to pull the top 10 loginids based on the number of "submissionid"s. I would like to display them in a 3-column HTML table that shows the "username" in the first column, the number of "submissionid"s in the second column, and the number of "commentid"s in the third column. I tried using the query below but it did not work. Any idea why not? Thanks in advance, John $sqlStr = "SELECT l.username ,l.loginid ,c.commentid ,count(s.commentid) countComments ,c.comment ,c.datecommented ,s.submissionid ,count(s.submissionid) countSubmissions ,s.title ,s.url ,s.displayurl ,s.datesubmitted FROM comment AS c INNER JOIN login AS l ON c.loginid = l.loginid INNER JOIN submission AS s ON c.loginid = s.loginid GROUP BY c.loginid ORDER BY countSubmissions DESC LIMIT 10"; $result = mysql_query($sqlStr); $arr = array(); echo "<table class=\"samplesrec1\">"; while ($row = mysql_fetch_array($result)) { echo '<tr>'; echo '<td class="sitename1"><a href="http://www...com/.../members/index.php?profile='.$row["username"].'">'.stripslashes($row["username"]).'</a></td>'; echo '</tr>'; echo '<td class="sitename1">'.stripslashes($row["countSubmissions"]).'</td>'; echo '</tr>'; echo '</tr>'; echo '<td class="sitename1">'.stripslashes($row["countComments"]).'</td>'; echo '</tr>'; } echo "</table>";

• LNK2001 error when compiling windows forms application with VC++ 2008

  I've been trying to write a small application which will work with mysql in C++. I am using MySQL server 5.1.41 and MySQL C++ connector 1.0.5.

• Where'd my sounds go?

  - by Dane Man

  In my Row class I have the initWithCoder method and everything restored in that method works fine, but only within the method. After the method is called I loose an array of sounds that is in my Row class. The sounds class also has the initWithCoder method, and the sound plays fine but only in the Row class initWithCoder method. After decoding the Row object, the sound array disappears completely and is unable to be called. Here's my source for the initWithCoder: - (id) initWithCoder:(NSCoder *)coder { ... soundArray = [coder decodeObjectForKey:@"soundArray"]; NSLog(@"%d",[soundArray count]); return self; } the log shows the count as 8 like it should (this is while unarchiving). Then the row object I create gets assigned. And the resulting row object no longer has a soundArray. [NSKeyedArchiver archiveRootObject:row toFile:@"DefaultRow"]; ... row = [NSKeyedUnarchiver unarchiveObjectWithFile:@"DefaultRow"]; So now whenever I call the soundArray it crashes. //ERROR IS HERE NSLog(@"%d",[[row soundArray] count]); Help please (soundArray is an NSMutableArray).

• div stacking/layout with css or javascript

  - by liz

  so i have 4 divs (i actually have many more but this will simplify the question). i want to display them in two columns. the 4 divs vary in height. the number of actual divs in the end will vary. so if i have this <div id="1" style="height: 200px" class="inline">some content here</div> <div id="2" style="height: 600px" class="inline">some content here</div> <div id="3" style="height: 300px" class="inline">some content here</div> <div id="4" style="height: 200px" class="inline">some content here</div> with styling thus .inline { display: inline-block; vertical-align: top; width: 48%;} so #1 would go left and then #2 would shove up beside it to the right, great, but the #3 will not slide up the 400px to fit nicely below #1. (of course)... it goes on the left side but at 600px from the top clearing the bottom of #2. etc... how would i get the divs to slide up into the empty spaces, is it possible with css? jquery maybe? i know i could write column divs to mark it up, but since the number of divs constantly change and the heights vary according to content. It would be nice to just get rid of the space since we dont really care about the order. any thoughts?

• Why compiling in Flash IDE I cannot access stage in a Sprite constructor before addChild while if I

  - by yuri

  I've created this simple class (omissing package directive and imports) public class Viewer extends Sprite { public function Viewer():void { trace(stage); } } then in Flash IDE I import in first frame this AS: import Viewer var viewer = new Viewer(); stage.addChild(viewer); trace(viewer.stage); and this works as I expected: the first trace called in constructor say stage is "null" because I haven't yet add viewer to a DisplayObjectContainer. The second one output the stage object. So I created a project using AXDT eclipse plugin, I've recreated and compiled only the first class (trashed the AS init script used in Flash IDE because is not needed) and on the first trace ... wow ... the stage is filled with the stage Object. I seems to me that the compiler used by AXDT (Flex4 SDK open source) add the class... before construct it (!?).. to a DisplayObjectContainer already attached to a Stage. I want to understand how can reproduce this behaviour using compiler in Flash IDE so I can directrly access Stage in construction.
