  • Question about JSON?

    - by Alex
    Hi all, I have a fairly simple question: In Javascript how can I return the boolean (if its found in the JSON) rather than the actual value? Example: var myJSON = { "foo" : "bar", "bar" : "foo" }; var keyToLookFor = "foo"; var found = myJSON[keyToLookFor]; if (found) { // I know I can test if the string exists in the if } // but is there a way I could just return something like: return found; // instead of testing found in the if statement and then returning true?

  • How can I tell if the screen is on in android?

    - by user297020
    In Android 2.2 (Level 7) the function PowerManager.IsScreenOn() returns a boolean that is true if the screen is turned on and false if the screen is turned off. I am developing code for Android 1.5 (Level 3). How do I accomplish the same task in older versions of Android? I do not want to turn the screen on or off in my code. I just want to know what it is.

  • Is there a work around for slow performance of do.call(cbind.xts,...) in R 2.15.2?

    - by Petr Matousu
    I would expect cbind.xts and do.call(cbind.xts) to perform with similar elapsed time. That was true for R2.11, R2.14. For R2.15.2 and xts 0.8-8, the do.call(cbind.xts,...) variant performs drastically slower, which effectively breaks my previous codes. As Josh Ulrich notes in a comment below, the xts package maintainers are aware of this problem. In the meantime, is there a convenient work around?

  • Writing exceptions in multihreaded windows service to event log

    - by Ziplin
    I have a multithreaded windows service that will unpredictably stop running once every 24 hours or so. I am writing to the event log and that's going through just fine, but whenever the service crashes there are no messages in the event log (even that the service stopped, despite having AutoLog=true). Is there a way to have uncaught exceptions written straight to the log, even if they aren't in the original thread?

  • SimpleMembership updating the "isconfirmed" flag

    - by Vijay V
    My Users table (the one that I created) has the following columns: UserId,UserName,FirstName,LastName,DOB After I ran this command WebSecurity.InitializeDatabaseConnection("DefaultConnection", "Users", "UserId", "UserName", autoCreateTables: true); it created the required simple membership tables for me. How would I go about "UnConfirming" an user or setting the "IsConfirmed" flag to false in the webpages_Membership using the new SimpleMembership API? (Earlier, before going to simplemembership using the "Membership" class I could update an user using the api call : Membership.UpdateUser( user );)

  • How do I Print a dynamically created Flex component/chart that is not being displayed on the screen?

    - by Adam Jones
    I have a several chart components that I have created in Flex. Basically I have set up a special UI that allows the user to select which of these charts they want to print. When they press the print button each of the selected charts is created dynamically then added to a container. Then I send this container off to FlexPrintJob. i.e. private function prePrint():void { var printSelection:Box = new Box(); printSelection.percentHeight = 100; printSelection.percentWidth = 100; printSelection.visible = true; if (this.chkMyChart1.selected) { var rptMyChart1:Chart1Panel = new Chart1Panel(); rptMyChart1.percentHeight = 100; rptMyChart1.percentWidth = 100; rptMyChart1.visible = true; printSelection.addChild(rptMyChart1); } print(printSelection); } private function print(container:Box):void { var job:FlexPrintJob; job = new FlexPrintJob(); if (job.start()) { job.addObject(container, FlexPrintJobScaleType.MATCH_WIDTH); job.send(); } } This code works fine if the chart is actually displayed somewhere on the page but adding it dynamically as shown above does not. The print dialog will appear but nothing happens when I press OK. So I really have two questions: Is it possible to print flex components/charts when they are not visible on the screen? If so, how do I do it / what am I doing wrong? UPDATE: Well, at least one thing wrong is my use of the percentages in the width and height. Using percentages doesn't really make sense when the Box is not contained in another object. Changing the height and width to fixed values actually allows the printing to progress and solves my initial problem. printSelection.height = 100; printSelection.width = 100; But a new problem arises in that instead of seeing my chart, I see a black box instead. I have previously resolved this issue by setting the background colour of the chart to #FFFFFF but this doesn't seem to be working this time. UPDATE 2: I have seen some examples on the adobe site that add the container to the application but don't include it in the layout. This looks like the way to go. i.e. printSelection.includeInLayout = false; addChild(printSelection);

  • My first Lisp macro; is it leaky?

    - by Tom Martin
    I've been working through Practical Common Lisp and as an exercise decided to write a macro to determine if a number is a multiple of another number: (defmacro multp (value factor) `(= (rem ,value ,factor) 0)) so that : (multp 40 10) evaluates to true whilst (multp 40 13) does not The question is does this macro leak in some way? Also is this "good" Lisp? Is there already an existing function/macro that I could have used?

  • How to Update TreeViewItem's IsExpanded property to false in code behind?

    - by viky
    I am working with WPF TreeView control. I am creating a hierarchical data structure and assigning it to ItemsSource and it will generate TreeviewItems automatically. By default I use IsExpanded of TreeViewItem to true. But in a particular case, I want to set IsExpanded property to false. So that treeview loading doesn't take time to generate all items. How can I set that in code since I don't have reference to TreeViewItem's instance at that time?

  • Why oh why doesn't my asp.net treeview update?

    - by Brendan
    I'm using an ASP.net treeview on a page with a custom XmlDataSource. When the user clicks on a node of the tree, a detailsview pops up and edits a bunch of things about the underlying object. All this works properly, and the underlying object gets updated in my background object-management classes. Yay! However, my treeview just isn't updating the display. Either immediately (which i would like it to), or on full page re-load (which is the minimal useful level i need it to be at). Am i subclassing XmlDataSource poorly? I really don't know. Can anyone point me in a good direction? Thanks! The markup looks about like this (chaff removed): <data:DefinitionDataSource runat="server" ID="DefinitionTreeSource" RootDefinitionID="uri:1"></data:DefinitionDataSource> <asp:TreeView ID="TreeView" runat="server" DataSourceID="DefinitionTreeSource"> <DataBindings> <asp:TreeNodeBinding DataMember="definition" TextField="name" ValueField="id" /> </DataBindings> </asp:TreeView> <asp:DetailsView ID="DetailsView1" runat="server" AutoGenerateRows="False" DataKeyNames="Id" DataSourceID="DefinitionSource" DefaultMode="Edit"> <Fields> <asp:BoundField DataField="Name" HeaderText="Name" HeaderStyle-Wrap="false" SortExpression="Name" /> <asp:CommandField ShowCancelButton="False" ShowInsertButton="True" ShowEditButton="True" ButtonType="Button" /> </Fields> </asp:DetailsView> And the DefinitionTreeSource code looks like this: public class DefinitionDataSource : XmlDataSource { public string RootDefinitionID { get { if (ViewState["RootDefinitionID"] != null) return ViewState["RootDefinitionID"] as String; return null; } set { if (!Object.Equals(ViewState["RootDefinitionID"], value)) { ViewState["RootDefinitionID"] = value; DataBind(); } } } public DefinitionDataSource() { } public override void DataBind() { base.DataBind(); setData(); } private void setData() { String defXML = "<?xml version=\"1.0\" ?>"; Test.Management.TestManager.Definition root = Test.Management.TestManager.Definition.GetDefinitionById(RootDefinitionID); if (root != null) this.Data = defXML + root.ToXMLString(); else this.Data = defXML + "<definition id=\"null\" name=\"Set Root Node\" />"; } } }

  • jQuery ajax multiline "script" response

    - by Rendrik
    I'm designing a template creation tool, which uses a jQuery Ajax request that posts parameters to a PHP file. The PHP does the actual generation of the template's HTML. // Send for processing. Expect JS back to execute. function generate() { $.ajax({ type: "POST", url: "generate.php", data: $('#genform :input').serialize(), dataType: "script", beforeSend: function() { $("#loading").html("<img src='images/loadbar.gif' />"); $("#loading") .dialog({ height: 80, width: 256, autoOpen: true, modal: true }); }, success: function(data) { $("#loading").dialog('close'); } }); } My trouble is that I have the ajax dataType: set to "script". Using this, the PHP file generates some jQuery dialogs for any errors which works nicely. However, after I generate the HTML, i'm having trouble passing it back. So I have probably 100 lines of generated HTML and javascript which i'd like to work with. In the PHP file, i've tried: echo('$("#result").html("'.$html.'");'); This does actually work if there are NO line breaks in $html. As soon as there are any line breaks, the Chrome debugger reports "gen.html:1 Uncaught SyntaxError: Unexpected token ILLEGAL". It's obvious that it's trying to eval the returned response headers, but is stopping at any line break. So, to be clear, when I pass $html back, if the contents are this: $html = "<div>hi there</div>"; It works fine (all of my error message dialogs are one line). But if it's: $html = "<div> hi there </div>"; It blows up. I'm really not sure how to get around this, or if there's a better way to go about it. It's important to me to keep the formatting so people can copy the HTML template. I may just break down and display the template file on the PHP page if I can't solve this, but I was really hoping to keep everything within the confines of the HTML page.

  • It is only uploading first row's file input

    - by user1304328
    I have a application which you can access here. If you open the application please click on the "Add" button a couple of times. This will add a new row into a table below. In each table row there is an AJAX file uploader. Now the problem is that if I click on the "Upload" button in any row except the first row, then the uploading only happens in the first row so it is only uploading the first file input only. Why is it doing this and how can I get it so that when then the user clicks the "Upload" button, the file input within that row of the "Upload" button is uploaded and not the first row being uploaded? Below is the full code where it appends the file AJAX file uploaded in each table row: function insertQuestion(form) { var $tbody = $('#qandatbl > tbody'); var $tr = $("<tr class='optionAndAnswer' align='center'></tr>"); var $image = $("<td class='image'></td>"); var $fileImage = $("<form action='upload.php' method='post' enctype='multipart/form-data' target='upload_target' onsubmit='startUpload();' >" + "<p id='f1_upload_process' align='center'>Loading...<br/><img src='Images/loader.gif' /><br/></p><p id='f1_upload_form' align='center'><br/><label>" + "File: <input name='fileImage' type='file' class='fileImage' /></label><br/><label><input type='submit' name='submitBtn' class='sbtn' value='Upload' /></label>" + "</p> <iframe id='upload_target' name='upload_target' src='#' style='width:0;height:0;border:0px solid #fff;'></iframe></form>"); $image.append($fileImage); $tr.append($image); $tbody.append($tr); } function startUpload(){ document.getElementById('f1_upload_process').style.visibility = 'visible'; document.getElementById('f1_upload_form').style.visibility = 'hidden'; return true; } function stopUpload(success){ var result = ''; if (success == 1){ result = '<span class="msg">The file was uploaded successfully!<\/span><br/><br/>'; } else { result = '<span class="emsg">There was an error during file upload!<\/span><br/><br/>'; } document.getElementById('f1_upload_process').style.visibility = 'hidden'; document.getElementById('f1_upload_form').innerHTML = result + '<label>File: <input name="fileImage" type="file"/><\/label><label><input type="submit" name="submitBtn" class="sbtn" value="Upload" /><\/label>'; document.getElementById('f1_upload_form').style.visibility = 'visible'; return true; }

  • Managing several custom content types from one module(drupal)

    - by Andrew
    Is it possible to declare and manage several custom content types inside one module? I'm creating a site that needs four custom content types and I'd like to manage them from one module instead of creating module for every content type. After some testing, I found out that it seems impossible. Because, unless hook_form and content type share the same name of module, drupal doesn't call hook_form. Here's how I'd like to do - function mycontent_node_info(){ return array( 'mycontent1' => array( 'name' => t('....'), 'module' => 'mycontent', 'description' => t('...), 'has_title' => TRUE, 'title_label' => t('Title'), 'has_body' => TRUE, 'body_label' => t('content body'), ), 'mycontent2' => array( ....... ), 'mycontent3' => array( ...... ), 'mycontent4' => array( ...... ), ); } function mycontent1_form(&$node){ $form['control1'] = array( '#type' => 'select', '#options' => array( '0' => t('selection 1'), '1' => t('selection 2'), ), '#attributes' => array('id'=>'control1'), ); $form['control2'] = array( '#type' => 'select', '#options' => array( '0' => t('1'), '1' => t('2'), '2' => t('3'), '3' => t('4'), ), '#attributes' => array('id'=>'control2'), ); return $form; } function mycontent2_form(&$node){ .... } function mycontent3_form(&$node){ .... } function mycontent4_form(&$node){ .... } Am I doing something wrong here or is not possible and there's no alternative other than creating module for every content types. I appreciate much your help.

  • Casting to derived type problem in C++

    - by GONeale
    Hey there everyone, I am quite new to C++, but have worked with C# for years, however it is not helping me here! :) My problem: I have an Actor class which Ball and Peg both derive from on an objective-c iphone game I am working on. As I am testing for collision, I wish to set an instance of Ball and Peg appropriately depending on the actual runtime type of actorA or actorB. My code that tests this as follows: // Actors that collided Actor *actorA = (Actor*) bodyA->GetUserData(); Actor *actorB = (Actor*) bodyB->GetUserData(); Ball* ball; Peg* peg; if (static_cast<Ball*> (actorA)) { // true ball = static_cast<Ball*> (actorA); } else if (static_cast<Ball*> (actorB)) { ball = static_cast<Ball*> (actorB); } if (static_cast<Peg*> (actorA)) { // also true?! peg = static_cast<Peg*> (actorA); } else if (static_cast<Peg*> (actorB)) { peg = static_cast<Peg*> (actorB); } if (peg != NULL) { [peg hitByBall]; } Once ball and peg are set, I then proceed to run the hitByBall method (objective c). Where my problem really lies is in the casting procedurel Ball casts fine from actorA; the first if (static_cast<>) statement steps in and sets the ball pointer appropriately. The second step is to assign the appropriate type to peg. I know peg should be a Peg type and I previously know it will be actorB, however at runtime, detecting the types, I was surprised to find actually the third if (static_cast<>) statement stepped in and set this, this if statement was to check if actorA was a Peg, which we already know actorA is a Ball! Why would it have stepped here and not in the fourth if statement? The only thing I can assume is how casting works differently from c# and that is it finds that actorA which is actually of type Ball derives from Actor and then it found when static_cast<Peg*> (actorA) is performed it found Peg derives from Actor too, so this is a valid test? This could all come down to how I have misunderstood the use of static_cast. How can I achieve what I need? :) I'm really uneasy about what feels to me like a long winded brute-casting attempt here with a ton of ridiculous if statements. I'm sure there is a more elegant way to achieve a simple cast to Peg and cast to Ball dependent on actual type held in actorA and actorB. Hope someone out there can help! :) Thanks a lot.
