  • Why does the roll_out event fire in this code?

    - by user339681
    I have made this simple example to demonstrate some problems I'm having. <?xml version="1.0" encoding="utf-8"?> <mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute"> <mx:Canvas id="buttonCanvas" x="100" y="100" opaqueBackground="#000000" width="80%" height="300" creationComplete="init(event)"> <mx:Button x="5" y="5"/> <mx:Button x="5" y="50"/> </mx:Canvas> <mx:Script> <![CDATA[ private function init(event:Event):void{ buttonCanvas.addEventListener(MouseEvent.ROLL_OUT, function(event:Event):void{ buttonCanvas.opaqueBackground=(buttonCanvas.opaqueBackground==0)? 0x666666:0; }); } ]]> </mx:Script> </mx:Application> I don't understand the following: Why doesn't the percentage nor absolute dimensions affect the canvas? Why does the roll_out event fire when the mouse leaves a button (even when it is still inside the canvas). I'm going nuts trying to figure this out. Any help would be greatly appreciated!

  • AngularJS Templates run twice

    - by Curt
    I'm working on an AngularJS web app with Twitter Bootstrap. The templates run twice. I don't know why they do this. Below is some of the code in the index.html file: <html data-ng-app="app" ng-controller="AppCtrl"> <div class="container ng-view" data-ng-view></div> ... <script> (function (angular) { "use strict"; // jshint ;_; // http://coenraets.org/blog/2012/02/sample-application-with-angular-js/ angular.module('app', ['filters', 'angular', 'currency']) .config(function($routeProvider) { var _view_ = 'view/'; $routeProvider. when('/app', {templateUrl:_view_+'app/index.html', }). when('/account/settings', {templateUrl:_view_+'app/settings.html', }). when('/profile/:profile_ID', {templateUrl:_view_+'app/profile.html', controller:ProfilePageCtrl}). when('/discuss', {templateUrl:_view_+'discuss/discuss.html', controller:DiscussCtrl}). when('/', {templateUrl:_view_+'page/home.html' }). when('/:page', {templateUrl:_view_+'page.html', controller:PageCtrl}). otherwise({redirectTo:'/'}); }) ... Can anybody provide suggestions? Are the templates supposed to run twice? 2012-12-04 Update: I found out that the templates are running twice, not the controller.

  • Generics Java and Shadowing of type parameters

    - by rubixibuc
    This code seems to work fine class Rule<T> { public <T>Rule(T t) { } public <T> void Foo(T t) { } } Does the method type parameter shadow the class type parameter? Also when you create an object does it use the type parameter of the class? example Rule<String> r = new Rule<String>(); Does this normally apply to the type parameter of the class, in the situation where they do not conflict? I mean when only the class has a type parameter, not the constructor, or does this look for a type parameter in the constructor? If they do conflict how does this change? SEE DISCUSSION BELOW if I have a function call x = <Type Parameter>method(); // this is a syntax error even inside the function or class ; I must place a this before it, why is this, and does everything still hold true. Why don't I need to prefix anything for the constructor call. Shouldn't Oracle fix this.

  • Get the parent class of a null object (C# Reflection)

    - by Nick
    How would I get the parent class of an object that has a value of null? For example... 'Class A' contains 'int? i' which is not set to any value when the class is created. Then in some other place in the code I want to pass in 'i' as a parameter to some function. Using 'i' as the only info, I want to be able to figure out that 'Class A' "owns" 'i'. The reason for this is because 'Class A' also contains some other object, and I want to call this other object's value from that same function mentioned in the above paragraph. Could also be: public class A { public class B { public int? i; public int? j; } B classBInstance = new B(); public string s; } { ... A someClassAInstance = new A(); ... doSomething(someClassAInstance.classBInstance.i); ... } public static bool doSomething(object theObject) { string s = /* SOMETHING on theObject to get to "s" from Class A */; int someValue = (int)theObject; }

  • jQuery: Preventing an event from being attached more than once?

    - by Evan Carroll
    Essentially, I have an element FOO that I want when clicked to attach a click event to a completely separate set of elements BAR, so that when they're clicked they can revert FOO to its previous content. I only want this event attached once. When FOO is clicked, its content is cached away in $back_up, and a trigger is added on the BAR set so that when clicked they can revert FOO back to its previous state. Is there a clever way to do this? Like to only .bind() if the event doesn't already exist? $('<div class="noprint little check" />').click( function () { var $warranty_explaination = $(this).closest('.page').children('.warranty_explaination'); var $back_up = $warranty_explaination.clone(true); $(this).closest('.page').find('.warranties .check:not(.noprint)').click( function () { /* This is the code I don't want to fire more than once */ /*, I just want it to be set to whatever is in the $back_up */ alert('reset'); $warranty_explaination.replaceWith( $back_up ) } ); $warranty_explaination.html('asdf') } ) Currently, the best way I can think to do this is to attach a class, and select where that class doesn't exist.

  • How to parse a string (by a "new" markup) with R ?

    - by Tal Galili
    Hi all, I want to use R to do string parsing that (I think) is like a simplistic HTML parsing. For example, let's say we have the following two variables: Seq <- "GCCTCGATAGCTCAGTTGGGAGAGCGTACGACTGAAGATCGTAAGGtCACCAGTTCGATCCTGGTTCGGGGCA" Str <- ">>>>>>>..>>>>........<<<<.>>>>>.......<<<<<.....>>>>>.......<<<<<<<<<<<<." Say that I want to parse "Seq" According to "Str", by using the legend here Seq: GCCTCGATAGCTCAGTTGGGAGAGCGTACGACTGAAGATCGTAAGGtCACCAGTTCGATCCTGGTTCGGGGCA Str: >>>>>>>..>>>>........<<<<.>>>>>.......<<<<<.....>>>>>.......<<<<<<<<<<<<. | | | | | | | || | +-----+ +--------------+ +---------------+ +---------------++-----+ | Stem 1 Stem 2 Stem 3 | | | +----------------------------------------------------------------+ Stem 0 Assume that we always have 4 stems (0 to 3), but that the length of letters before and after each of them can very. The output should be something like the following list structure: list( "Stem 0 opening" = "GCCTCGA", "before Stem 1" = "TA", "Stem 1" = list(opening = "GCTC", inside = "AGTTGGGA", closing = "GAGC" ), "between Stem 1 and 2" = "G", "Stem 2" = list(opening = "TACGA", inside = "CTGAAGA", closing = "TCGTA" ), "between Stem 2 and 3" = "AGGtC", "Stem 3" = list(opening = "ACCAG", inside = "TTCGATC", closing = "CTGGT" ), "After Stem 3" = "", "Stem 0 closing" = "TCGGGGC" ) I don't have any experience with programming a parser, and would like advices as to what strategy to use when programming something like this (and any recommended R commands to use). What I was thinking of is to first get rid of the "Stem 0", then go through the inner string with a recursive function (let's call it "seperate.stem") that each time will split the string into: 1. before stem 2. opening stem 3. inside stem 4. closing stem 5. after stem Where the "after stem" will then be recursively entered into the same function ("seperate.stem") The thing is that I am not sure how to try and do this coding without using a loop. Any advices will be most welcomed.

  • How do I stop events from bubbling/multiple events with animated mouseovers?

    - by Kurucu
    I noticed a lot of JQuery answers on this, but I'm using MooTools... I have a Table of Contents which uses CSS Fixed positioning to keep it off to the left side, except for 20 pixels. The user hovers their cursor over the 20 pixels, which fires the DIV's mouseover event and the ToC slides fully into the page. When the cursor leaves, the ToC slides back to where it was. $('frameworkBreakdown').addEvents({ 'mouseover': function(event){ event = new Event(event); $('frameworkBreakdown').tween('left', 20); event.stop; }, 'mouseout': function(event){ event = new Event(event); $('frameworkBreakdown').tween('left', (10 - $('frameworkBreakdown').getStyle('width').toInt()) ); event.stop; } }); This works well (aside from unrelated issues) except that when I move the mouse on the DIV it starts to jitter, presumably because the contents of the DIV are also firing the event, or the event refires as the mouse tracks over the DIV. How can I stop this behaviour from occuring? Is there a standard method, or do I use some sort of nast global variable that determines whether effects are in action, and thus ignore the event?

  • Is it advisable to have an interface as the return type?

    - by wb
    I have a set of classes with the same functions but with different logic. However, each class function can return a number of objects. It is safe to set the return type as the interface? Each class (all using the same interface) is doing this with different business logic. protected IMessage validateReturnType; <-- This is in an abstract class public bool IsValid() <-- This is in an abstract class { return (validateReturnType.GetType() == typeof(Success)); } public IMessage Validate() { if (name.Length < 5) { validateReturnType = new Error("Name must be 5 characters or greater."); } else { validateReturnType = new Success("Name is valid."); } return validateReturnType; } Are there any pitfalls with unit testing the return type of an function? Also, is it considered bad design to have functions needing to be run in order for them to succeed? In this example, Validate() would have to be run before IsValid() or else IsValid() would always return false. Thank you.

  • Getting jsonString via Jquery coming up empty

    I'm using asp mvc and I'm getting data in one part of my program like this public List<IncidentPerAreaCount> getIncident() { int RondeboschCounter = 0; int ClaremontCounter = 0; int AthloneCounter = 0; List<IncidentPerAreaCount> IncidentAreaCount = new List<IncidentPerAreaCount>(); IncidentPerAreaCount Rondebosch = new IncidentPerAreaCount(); IncidentPerAreaCount Claremont = new IncidentPerAreaCount(); IncidentPerAreaCount Athlone = new IncidentPerAreaCount(); List<Report> Reports = GetReports(); for (int i = 0; i < Reports.Count(); i++) { if (Reports.AsEnumerable().ElementAt(i).Area == "Rondebosch") { RondeboschCounter++; } else if (Reports.AsEnumerable().ElementAt(i).Area == "Claremont") { ClaremontCounter++; } else if (Reports.AsEnumerable().ElementAt(i).Area == "Athlone") { AthloneCounter++; } } Rondebosch.AreaName = "Rondebosch"; Rondebosch.NumberOfIncidents = RondeboschCounter; Claremont.AreaName = "Claremont"; Claremont.NumberOfIncidents = ClaremontCounter; Athlone.AreaName = "Athlone"; Athlone.NumberOfIncidents = AthloneCounter; IncidentAreaCount.Add(Rondebosch); IncidentAreaCount.Add(Claremont); IncidentAreaCount.Add(Athlone); return IncidentAreaCount; } Then I'm trying to get this string via Jquery var Reports = []; $.ajax({ url: "Home/getIncident", async: false, dataType: 'json', success: function (json) { Reports = json.whatever; } }); alert(Reports); However the alert function keeps coming up empty (ie empty textbox) instead of having a json formatted string with data.

  • PHP Mail() not working on remote server

    - by Amaerth
    I am developing an application and have been testing the mail() function in PHP. The following works just fine on my local machine to send emails to myself, but as soon as I try to send it from the testing environment to my local machine, it silently fails. I will still get the "Mail Sent" message, but no message is sent. I turned on the mail logging in the php.ini file, but even that doesn't seem to be populated after I refresh the page. Again, the .php files and php.ini files are identical in both environments. Port 25 has been opened on the testing environment, and we are using a Microsoft Exchange server. <?php $to = "[email protected]"; $subject = "Test mail"; $message = "Hello! This is a simple email message."; $from = "[email protected]"; $headers = "From:" . $from; mail($to,$subject,$message,$headers); echo "Mail Sent."; ?> SMTP area of the php.ini file: [mail function] ; For Win32 only. ; http://php.net/smtp SMTP = exhange.server.org ; http://php.net/smtp-port smtp_port = 25 ; For Win32 only. ; http://php.net/sendmail-from sendmail_from = [email protected]

  • why doesnt this program print?

  • Change jQuery slider option dynamically based on window width

    - by Nathan
    I would like to change a jQuery option based on window width (on load as well as on resize). I've found solutions close to what I need, but I don't understand jQuery or javascript enough to customize them for my needs. Here's my jQuery code: <script type="text/javascript"> var tpj = jQuery; tpj.noConflict(); tpj(document).ready(function () { if (tpj.fn.cssOriginal != undefined) tpj.fn.css = tpj.fn.cssOriginal; tpj('#rev_slider_1_1').show().revolution({ delay: 5000, startwidth: 1920, startheight: 515, hideThumbs: 200, thumbWidth: 100, thumbHeight: 50, thumbAmount: 4, navigationType: "bullet", navigationArrows: "verticalcentered", navigationStyle: "navbar", touchenabled: "on", onHoverStop: "off", navOffsetHorizontal: 0, navOffsetVertical: 20, shadow: 0, fullWidth: "on" }); }); //ready </script> I want to change the startheight based on window width. If the window width is above 1280 I would like the value for the height to be 515, and if it is below 1280 I would like the height to be 615 and if the width is less than 480 make the height 715. With help from another post I am able to change the css I need using this script: $(window).on('load resize', function () { var w = $(window).width(); $("#rev_slider_1_1 #rev_slider_1_1_wrapper") .css('max-height', w > 1280 ? 515 : w > 480 ? 615 : 715); }); But I need to also change the jQuery startheight value on the fly. Can someone help? Thanks!

  • Overwriting a range of bits in an integer in a generic way

    - by porgarmingduod
    Given two integers X and Y, I want to overwrite bits at position P to P+N. Example: int x = 0xAAAA; // 0b1010101010101010 int y = 0x0C30; // 0b0000110000110000 int result = 0xAC3A; // 0b1010110000111010 Does this procedure have a name? If I have masks, the operation is easy enough: int mask_x = 0xF00F; // 0b1111000000001111 int mask_y = 0x0FF0; // 0b0000111111110000 int result = (x & mask_x) | (y & mask_y); What I can't quite figure out is how to write it in a generic way, such as in the following generic C++ function: template<typename IntType> IntType OverwriteBits(IntType dst, IntType src, int pos, int len) { // If: // dst = 0xAAAA; // 0b1010101010101010 // src = 0x0C30; // 0b0000110000110000 // pos = 4 ^ // len = 8 ^------- // Then: // result = 0xAC3A; // 0b1010110000111010 } The problem is that I cannot figure out how to make the masks properly when all the variables, including the width of the integer, is variable. Does anyone know how to write the above function properly?

  • Calling member functions dynamically

    - by user652511
    I'm pretty sure it's possible to call a class and its member function dynamically in Delphi, but I can't quite seem to make it work. What am I missing? // Here's a list of classes (some code removed for clarity) moClassList : TList; moClassList.Add( TClassA ); moClassList.Add( TClassB ); // Here is where I want to call an object's member function if the // object's class is in the list: for i := 0 to moClassList.Count - 1 do if oObject is TClass(moClassList[i]) then with oObject as TClass(moClassList[i]) do Foo(); I get an undeclared identifier for Foo() at compile. Clarification/Additional Information: What I'm trying to accomplish is to create a Change Notification system between business classes. Class A registers to be notified of changes in Class B, and the system stores a mapping of Class A - Class B. Then, when a Class B object changes, the system will call a A.Foo() to process the change. I'd like the notification system to not require any hard-coded classes if possible. There will always be a Foo() for any class that registers for notification. Maybe this can't be done or there's a completely different and better approach to my problem. By the way, this is not exactly an "Observer" design pattern because it's not dealing with objects in memory. Managing changes between related persistent data seems like a standard problem to be solved, but I've not found very much discussion about it. Again, any assistance would be greatly appreciated.

  • NullPointerException on Activity Testint Tutorial

    - by Bendik
    Hello, I am currently trying the activity testing tutorial (Found here), and have a problem. It seems that whenever I try to call something inside the UIThread, I get a java.lang.NullPointerException. public void testSpinnerUI() { mActivity.runOnUiThread( new Runnable() { public void run() { mSpinner.requestFocus(); } }); } This gives me: Incomplete: java.lang.NullPointerException and nothing else. I have tried this on two different samples now, with the same result. I tried with a try/catch clause around the mSpinner.requestFocus() call, and it seems that mSpinner is null inside the thread. I have set it properly up with the setUp() function found in the same sample, and a quick assertNotNull( mSpinner ) shows me that mSpinner is in fact not null after the setUp() function. What can be the cause of this? EDIT; ok, some more testing has been done. It seems that the application that is being tested resets between each test. This essentially makes me have to reinstantiate all variables between each test. Is this normal?

  • Automating Excel through the PIA makes VBA go squiffy.

    - by Jon Artus
    I have absolutely no idea how to start diagnosing this, and just wondered if anyone had any suggestions. I'm generating an Excel spreadsheet by calling some Macros from a C# application, and during the generation process it somehow breaks. I've got a VBA class containing all of my logging/error-handling logic, which I instantiate using a singleton-esque accessor, shown here: Private mcAppFramework As csys_ApplicationFramework Public Function AppFramework() As csys_ApplicationFramework If mcAppFramework Is Nothing Then Set mcAppFramework = New csys_ApplicationFramework Call mcAppFramework.bInitialise End If Set AppFramework = mcAppFramework End Function The above code works fine before I've generated the spreadsheet, but afterwards fails. The problem seems to be the following line; Set mcAppFramework = New csys_ApplicationFramework which I've never seen fail before. If I add a watch to the variable being assigned here, the type shows as csys_ApplicationFramework/wksFoo, where wksFoo is a random worksheet in the same workbook. What seems to be happening is that while the variable is of the right type, rather than filling that slot with a new instance of my framework class, it's making it point to an existing worksheet instead, the equivalent of Set mcAppFramework = wksFoo which is a compiler error, as one might expect. Even more bizarrely, if I put a breakpoint on the offending line, edit the line, and then resume execution, it works. For example, I delete the word 'New' move off the line, move back, re-type 'New' and resume execution. This somehow 'fixes' the workbook and it works happily ever after, with the type of the variable in my watch window showing as csys_ApplicationFramework/csys_ApplicationFramework as I'd expect. This implies that manipulating the workbook through the PIA is somehow breaking it temporarily. All I'm doing in the PIA is opening the workbook, calling several macros using Excel.Application.Run(), and saving it again. I can post a few more details if anyone thinks that it's relevant. I don't know how VBA creates objects behind the scenes or how to debug this. I also don't know how the way the code executes can change without the code itself changing. As previously mentioned, VBA has frankly gone a bit squiffy on me... Any thoughts?

  • Add Hover display for table cell

    - by Jake
    I have a table, but it is not in a list format, meaning not a column/row format. I look for specific cells to add a hover event that displays a description of the cell. $("#TableID td").hover(function(){ //ifCellThatIWant $(this).append("<span>Message that was brought in</span>"); }, function(){ $(this).children().remove(); }); The problem is right now is that the hover displays a span(with info. inside) that I used jquery to append the span to the cell when mouseover, which expands the cell, which is an effect that I don't like or want. I'm Trying to have an out of the table look,but still be by the cell that triggered the event; because if the span has a lot of info. in it, expanding the cell dynamically will start to look pretty nasty. Also will help if I had some type of css direction on how will I make the display for the mouseover "description" span look nice. My mind thought is that a way to accomplish what I want is giver the appended span the position of my mouse cursor when hover, but not sure if its the right approach or what the syntax would look like.

  • onKeypress Enter Key event on textfield not working in Chrome

    - by rlcrews
    I have a question along the same vein as the one asked here regarding how the enter key is handled in chrome. The effect I am trying to accomplish is to allow the enter key to call a click event of one a button while focus in within the current field. To accomplish this I am using the following code: javascript: <script type="text/javascript"> //attempting to capture keypress for chrome here but this is not working $("#txtContainer").keypress(function (e) { if (e.keyCode == '13') { e.preventDefault(); doClick(buttonname, e); return false; } }); function doClick(buttonName, e) { var key; if (window.event) key = window.event.keyCode; //IE else key = e.which; //firefox if (key == 13) { var btn = document.getElementById(buttonName); if (btn != null) { btn.click(); event.keyCode = 0 } } } </script> within the aspx <form id="form1" runat="server"> <div> <asp:LinkButton ID="newBtn" runat="server" OnClick="btnLogin_Click" Text="ASP Link" /> <asp:TextBox ID="txtContainer" runat="server" Width="100" /> <asp:Label ID="time_lbl" runat="server" /> </div> </form> and within the code behind aspx.cs protected void Page_Load(object sender, EventArgs e) { if (!IsPostBack) { txtContainer.Attributes.Add("onKeyPress", "doClick('" + newBtn.ClientID + "',event)"); } } public void btnLogin_Click(object sender, EventArgs e) { time_lbl.Text = txtContainer.Text; } The above code works fine in FF and IE however chrome continues to submit the entire form vs. capturing the keypress on the enterkey. Thank you for any suggestions.

    Hi, i've used a sample found on online and applied it to my code: <?php session_start(); if (isset($_REQUEST["email"])) { $_SESSION["name"] = true; $host = $_SERVER["HTTP_HOST"]; $path = dirname($_SERVER["PHP_SELF"]); $sid = session_name() . "=" . session_id(); header("Location: index.php?$sid"); exit; } ?> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> ... ... and rest of the html code When I open this page, I got an error: Warning: session_start() [function.session-start]: Cannot send session cookie - headers already sent by (output started at /data/server/user/directory/sub-directory/login.php:1) in /data/server/user/directory/sub-directory/login.php on line 2 Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent (output started at /data/server/user/directory/sub-directory/login.php:1) in /data/server/user/directory/sub-directory/login.php on line 2 I looked around to resolve this issue and saw few posts about this in this site also, but I just can't get a good grip on this...can't find the answer. Please help. Thanks.

  • javascript unable to locate a form using the ID tag

    - by ihake
    Here's my problem: I'm trying to set up a simple mobile contact form with a captcha built in. The page I'm working on can be found here: http://m.lancasterpainting.com/contact.php I'm using the following php contact form: http://www.html-form-guide.com/contact-form/php-email-contact-form.html I want to first say that I'm not the only one to run into this problem. After googling the issue, I've found multiple people struggling with this, but no-one seems to have an answer. Now for the problem... As you can see if you visit the page, each time the page is accessed, an error appears that says "Error: couldnot get Form object contact_form". I cannot--for the life of me--figure out why the javascript can't find the form I pass it. I call the function that generates this error at the top of the page: var frmvalidator = new Validator("contact_form"); The form I'm referencing is as follows in the HTML code: <div data-role="page" data-theme="e" id="contact_form" name="contact_form" data-position="inline"> ... And the function that is called that generates the error can be found in an external .js file here: http://m.lancasterpainting.com/scripts/gen_validatorv31.js Is there something that I am simply not seeing? Why can't the javascript locate the form? Thanks so much to anyone that helps with this.

  • Storing C++ templated objects as same type

    - by JaredC
    I have a class that is a core component of a performance sensitive code path, so I am trying to optimize it as much as possible. The class used to be: class Widget { Widget(int n) : N(n) {} .... member functions that use the constant value N .... const int N; // just initialized, will never change } The arguments to the constructor are known at compile time, so I have changed this class to a template, so that N can be compiled into the functions: template<int N> class Widget { .... member functions that use N .... } I have another class with a method: Widget & GetWidget(int index); However, after templating Widget, each widget has a different type so I cannot define the function like this anymore. I considered different inheritance options, but I'm not sure that the performance gain from the template would outweigh the cost of inherited function invocations. SO, my question is this: I am pretty sure I want the best of both worlds (compile-time / run-time), and it may not be possible. But, is there a way to gain the performance of knowing N at compile time, but still being able to return Widgets as the same type? Thanks!
