Why are these styles not visible in IE6

- by Laramie

Given the following markup <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML Strict//EN"><META http-equiv="Content-Type" content="text/html; charset=utf-8"> <HTML xmlns="http://www.w3.org/1999/xhtml"> <head> <style type="text/css"> div.apartBox { padding:12px; background: #FFFFFF; border: solid 1px #6182A3; } .browser { background: #fff; border: solid 1px #0055E3; border-top: solid 12px #0055E3; border-bottom: solid 4px #7A99C5; padding:10px 10px 8px 14px; color: #333; font: 0.8em/1 arial; margin: 8px 20px; } .callout { background: #EEF2F0; border: solid 1px #9CC7C0; padding:8px; } </style> </head> <BODY> <div class="apartBox" id="subPopout" style="Z-INDEX: 2; WIDTH: 400px; POSITION: relative"> <div id="upSubPop"> <div class="callout" id="subDetails"> <div class="browser"> <span id="txtExample">Me afecta que digan que soy incapaz.</span> </div> </div> </div> </div> </BODY></HTML> The styles from the css .browser and .callout are not visible in IE6 unless I manually remove the position:relative style from subPopout. This div is generated automatically from a modal popup so I unfortunately can't touch this style. It displays fine in FF. If I select the .browser div with my mouse, it displays when I unselect it!

Getting RGB values for each pixel from a 24bpp Bitmap in C

- by seven

Hello, i want to read the RGB values for each pixel from a .bmp file , so i can convert the bmp into a format suitable for gba . so i need to get just the RGB for each pixel and then write this information to a file. i am trying to use the windows.h structures : typedef struct { char signature[2]; unsigned int fileSize; unsigned int reserved; unsigned int offset; }BmpHeader; typedef struct { unsigned int headerSize; unsigned int width; unsigned int height; unsigned short planeCount; unsigned short bitDepth; unsigned int compression; unsigned int compressedImageSize; unsigned int horizontalResolution; unsigned int verticalResolution; unsigned int numColors; unsigned int importantColors; }BmpImageInfo; typedef struct { unsigned char blue; unsigned char green; unsigned char red; unsigned char reserved; }Rgb; typedef struct { BmpHeader header; BmpImageInfo info; Rgb colors[256]; unsigned short image[1]; }BmpFile; but i only need RGB struct. So lets say i read "in.bmp": FILE *inFile, *outFile; inFile = fopen("C://in.bmp", "rb"); Rgb Palette[256]; for(i=0;i<256;i++) { fread(&Palette[i],sizeof(Rgb),1,inFile); } fclose(inFile); is this correct ? how do i write only the RGB information to a file ? can anyone please give me some information please . Thank you.

How can I parse a namespace using the SAX parser?

- by Silvestri

Hello, Using a twitter search URL ie. http://search.twitter.com/search.rss?q=android returns CSS that has an item that looks like: <item> <title>@UberTwiter still waiting for @ubertwitter android app!!!</title> <link>http://twitter.com/meals69/statuses/21158076391</link> <description>still waiting for an app!!!</description> <pubDate>Sat, 14 Aug 2010 15:33:44 +0000</pubDate> <guid>http://twitter.com/meals69/statuses/21158076391</guid> <author>Some Twitter User</author> <media:content type="image/jpg" height="48" width="48" url="http://a1.twimg.com/profile_images/756343289/me2_normal.jpg"/> <google:image_link>http://a1.twimg.com/profile_images/756343289/me2_normal.jpg</google:image_link> <twitter:metadata> <twitter:result_type>recent</twitter:result_type> </twitter:metadata> </item> Pretty simple. My code parses out everything (title, link, description, pubDate, etc.) without any problems. However, I'm getting null on: <google:image_link> I'm using Java to parse the RSS feed. Do I have to handle compound localnames differently than I would a more simple localname? This is the bit of code that parses out Link, Description, pubDate, etc: @Override public void endElement(String uri, String localName, String name) throws SAXException { super.endElement(uri, localName, name); if (this.currentMessage != null){ if (localName.equalsIgnoreCase(TITLE)){ currentMessage.setTitle(builder.toString()); } else if (localName.equalsIgnoreCase(LINK)){ currentMessage.setLink(builder.toString()); } else if (localName.equalsIgnoreCase(DESCRIPTION)){ currentMessage.setDescription(builder.toString()); } else if (localName.equalsIgnoreCase(PUB_DATE)){ currentMessage.setDate(builder.toString()); } else if (localName.equalsIgnoreCase(GUID)){ currentMessage.setGuid(builder.toString()); } else if (uri.equalsIgnoreCase(AVATAR)){ currentMessage.setAvatar(builder.toString()); } else if (localName.equalsIgnoreCase(ITEM)){ messages.add(currentMessage); } builder.setLength(0); } } startDocument looks like: @Override public void startDocument() throws SAXException { super.startDocument(); messages = new ArrayList<Message>(); builder = new StringBuilder(); } startElement looks like: @Override public void startElement(String uri, String localName, String name, Attributes attributes) throws SAXException { super.startElement(uri, localName, name, attributes); if (localName.equalsIgnoreCase(ITEM)){ this.currentMessage = new Message(); } } Tony

Populating a PHP array within a foreach loop

- by patrick

I am wanting to add each user into an array and check for duplicates before I do. $spotcount = 10; for ($topuser_count = 0; $topuser_count < $spotcount; $topuser_count++) //total spots { $spottop10 = $ids[$topuser_count]; $top_10 = $gowalla->getSpotInfo($spottop10); $usercount = 0; $c = 0; $array = array(); foreach($top_10['top_10'] as $top10) //loop each spot { //$getuser = substr($top10['url'],7); //strip the url $getuser = ltrim($top10['url'], " users/" ); if ($usercount < 3) //loop only certain number of top users { if (($getuser != $userurl) && (array_search($getuser, $array) !== true)) { //echo " no duplicates! <br /><br />"; echo ' <a href= "http://gowalla.com'.$top10['url'].'"><img width="90" height="90" src= " '.$top10['image_url'].' " title="'.$top10['first_name'].'" alt="Error" /></a> '; $array[$c++] = $getuser; } else { //echo "duplicate <br /><br />"; } } $usercount++; } print_r($array); } The previous code prints: Array ( [0] => 62151 [1] => 204501 [2] => 209368 ) Array ( [0] => 62151 [1] => 33116 [2] => 122485 ) Array ( [0] => 120728 [1] => 205247 [2] => 33116 ) Array ( [0] => 150883 [1] => 248551 [2] => 248558 ) Array ( [0] => 157580 [1] => 77490 [2] => 52046 ) Which is wrong. It does check for duplicates, but only the contents of each foreach loop instead of the entire array. How is this if I am storing everything into $array?

Cannot interact with checkbox in FireFox or Chrome. Works in IE.

Title says it all. Here's the code: <div id="regpage"> <form action="" method="post"> <fieldset style="border:none;"> <div class="label">Username:</div> <input type="text" name="username" class="item" value="" /><br /> <div class="caption">Must be 5-15 characters</div><br /> <div style="clear:both;"></div> <div class="label">Password:</div> <input type="password" name="password" class="item" value="" /><br /> <div class="caption">Must be 6-20 characters</div><br /> <div style="clear:both;"></div> <div class="label">Email:</div> <input type="text" name="email" class="item" value="" /><br /> <div class="caption">Valid email address is required</div><br /> <div style="clear:both;"></div> <input name="terms" type="checkbox" id="terms" value="agree" /><div class="caption2"><label for="terms">I agree to the terms and conditions</label></div> <p><input type="submit" name="register" value="Register" id="register" style="float:left;border:1px solid #999;background:#E4E4E4;margin-top:5px;" /></p><br /> </fieldset> </form> </div> And the id "regpage" is definded in the style.css as: #regpage { width: 356px; height: 150px; color: #000000; font-family: "Tahoma", Arial, Helvetica, sans-serif; font-size: 13px; } If I move the checkbox OUT of it works just fine. But inside it will not interact in Mozilla. I've even tried adding onclick='this.checked="checked"' and it still does not interact. You can click until your blue in the face and nothing will happen. What's the deal! This is REALLY driving me batty.

dojo layout tutorial dor version 1.7 doesn't work for 1.7.2

- by Sheena

This is sortof a continuation to dojo1.7 layout acting screwy. So I made some working widgets and tested them out, i then tried altering my work using the tutorial at http://dojotoolkit.org/documentation/tutorials/1.7/dijit_layout/ to make the layout nice. After failing at that in many interesting ways (thus my last question) I started on a new path. My plan is now to implement the layout tutorial example and then stick in my widgets. For some reason even following the tutorial wont work... everything loads then disappears and I'm left with a blank browser window. Any ideas? It just struck me that it could be browser compatibility issues, I'm working on Firefox 13.0.1. As far as I know Dojo is supposed to be compatible with this... anyway, have some code: HTML: <body class="claro"> <div id="appLayout" class="demoLayout" data-dojo-type="dijit.layout.BorderContainer" data-dojo-props="design: 'headline'"> <div class="centerPanel" data-dojo-type="dijit.layout.ContentPane" data-dojo-props="region: 'center'"> <div> <h4>Group 1 Content</h4> <p>stuff</p> </div> <div> <h4>Group 2 Content</h4> </div> <div> <h4>Group 3 Content</h4> </div> </div> <div class="edgePanel" data-dojo-type="dijit.layout.ContentPane" data-dojo-props="region: 'top'"> Header content (top) </div> <div id="leftCol" class="edgePanel" data-dojo-type="dijit.layout.ContentPane" data-dojo-props="region: 'left', splitter: true"> Sidebar content (left) </div> </div> </body> Dojo Configuration: var dojoConfig = { baseUrl: "${request.static_url('mega:static/js')}", //this is in a mako template tlmSiblingOfDojo: false, packages: [ { name: "dojo", location: "libs/dojo" }, { name: "dijit", location: "libs/dijit" }, { name: "dojox", location: "libs/dojox" }, ], parseOnLoad: true, has: { "dojo-firebug": true, "dojo-debug-messages": true }, async: true }; other js stuff: require(["dijit/layout/BorderContainer", "dijit/layout/TabContainer", "dijit/layout/ContentPane", "dojo/parser"]); css: html, body { height: 100%; margin: 0; overflow: hidden; padding: 0; } #appLayout { height: 100%; } #leftCol { width: 14em; }

Stuck with jQuery thumbnail gallery behavior

- by Vitor

Hi everyone, I'm trying to create a simple thumbnail viewer with jQuery. Here goes the code: $(function(){ $("ul.thumbnails li").click(function(e){ var imgAlt = $(this).find('img').attr("alt"); //Get Alt Tag of Image var imgTitle = $(this).find('a').attr("href"); //Get Main Image URL $("img.featured").attr({ src: imgTitle , alt: imgAlt}); //Switch the main image (URL + alt tag) }); <div class="image-gallery"> <img class="featured" src="big.jpg"> <ul class="thumbnails"> <li id="thumb01"> <a href="big.jpg"><img src="small.jpg"></a> </li> <li id="thumb02"> <a href="big.jpg"><img src="small.jpg"></a> </li> <li id="thumb03"> <a href="big.jpg"><img src="small.jpg"></a> </li> </ul> .thumbnails li { margin: 0; padding: 5px 5px 0 5px; list-style: none; float: left; overflow: hidden; } thumbnails li img { width: 50px; height: 50px; margin: 0; padding: 0; float: left; } If i click the thumbnail, the browser goes straight to the full image instead of just changing the img src with jQuery. But I if i click somewhere inside the <li> it works. I know this must be simple, but I don't know where I'm going wrong. I've tried studying other galleries, like http://www.sohtanaka.com/web-design/examples/image-rotator/ , but couldn't find what I'm missing. I could really use some help from you guys :)

usercontrol hosted in IE renders as a textbox

- by coxymla

On my ongoing saga to mirror the hosting of a legacy app on a clean box, I've hit my next snag. One page relies on a big .NET UserControl that on the new machine renders only as a big, greyed out textarea (greyed out vertical scrollbar on the right hand edge. Inspecting the source shows the expected object tag.) This is particularly tricky because nobody seems to know much about hosted UserControls and all the discussions data back to 2002-2004. The page is quite simple: <%@ Page language="c#" Codebehind="DataExport.aspx.cs" AutoEventWireup="false" Inherits="yyyyy.Web.DataExport" %> <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN" > <html> <head> <title>DataExport</title> <link rel="Configuration" href="/xxxxx/yyyyy/DataExport.config"> </head> <body style="margin:0px;padding:0px;overflow:hidden"> <OBJECT id="DataExport" style="WIDTH: 100%; HEIGHT: 100%; position:absolute; left: 0px; top:0px" classid="yyyyy.Common.dll#yyyyy.Controls.DataExport" VIEWASTEXT> </OBJECT> </body> </html> The config file referenced: <?xml version="1.0" encoding="utf-8" ?> <configuration> <configSections> <sectionGroup name="yyyyy"> <section name="dataExport" type="yyyyy.Controls.DataExportSectionHandler,yyyyy.Common" /> </sectionGroup> </configSections> <yyyyy> <dataExport> <layoutFile>http://vm2/xxxxx/yyyyy/layout.xml</layoutFile> <webServiceUrl>http://vm2/xxxxx/yyyyy/services/yyyyy.asmx</webServiceUrl> </dataExport> </yyyyy> </configuration> What I've checked: Security permissions should be OK, the site is trusted and adding a URL exception to grant FullTrust doesn't change anything. Config file is acessible over the web, layout.xml is accessible, ASMX shows the expected command list Machine.config grants GET permission for the usercontrol.config file. What perhaps looks fishy to me: The DataExport UserControl references Aspose.Excel to generate the spreadsheets it exports. When I navigate to the page and get a blank textbox, then run gacutil /ldl, nothing is in the local download cache. On the working machine, running the same command after viewing the page shows a laundry list of DLLs including the control DLL and the Aspose DLL.

jQuery - addClass or removeClass - Is there an append class?

I have css hover over images for my tabs and I'm trying to get the class to change from .how to .how_on when I click on the image HOW.

IE7 is making my life miserable! Getting gaps between html table columns (w/ colspan) with css togg

- by Art Peterson

Copy/paste this html code snippet and try it out in IE7. When you toggle the hidden columns it leaves a gap between the columns. In Firefox it works fine, the columns touch when minimized. Haven't tried IE8 yet, would be curious to hear how it works there. Any ideas? I've tried a bunch of things in the CSS like table-layout:fixed but no luck. Note: Not looking for a different toggling method because the table I'm really dealing with is 50+ columns wide and 4000+ rows so looping/jquery techniques are too slow. Here's the code - if someone can re-post a working version of it I'll instantly give them the check and be forever in your debt! <DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd"> <html> <head> <script> function toggle() { var tableobj = document.getElementById("mytable"); if (tableobj.className == "") { tableobj.className = "hide1 hide2"; } else { tableobj.className = ""; } } </script> <style> table { border-collapse: collapse; } td, th { border: 1px solid silver; } .hide1 .col1 { display: none; } .hide2 .col2 { display: none; } </style> </head> <body> <input type="button" value="toggle" onclick="toggle();" /> <table id="mytable"> <tr> <th>A</th> <th colspan="2">B</th> <th colspan="2" class="col1">B1</th> <th colspan="2">C</th> <th colspan="2" class="col2">C1</th> </tr> <tr> <td>123</td> <td>456</td> <td>789</td> <td class="col1">123</td> <td class="col1">456</td> <td>789</td> <td>123</td> <td class="col2">456</td> <td class="col2">789</td> </tr> </table> </body> </html>

HTML5 Video Tag in Chrome - Why is currentTime ignored when video downloaded from my webserver?

- by larson4

I want to be able to play back video from a specific time using the HTML5 video tag (and currently only need to worry about Chrome). This is possible by setting the currentTime property of a video element. That works fine in Chrome with a video sourced from html5rocks.com, but is ignored when the same file is loaded from my own local webserver. Using the sample code from http://playground.html5rocks.com/#video_tag, I have arrived at the following HTML: <!DOCTYPE html> <html> <body> <video id="video1" width="320" height="240" volume=".7" controls preload=true autobuffer> <source src="http://playground.html5rocks.com/samples/html5_misc/chrome_japan.webm" type='video/webm; codecs="vp8, vorbis"'/> </video> <input type=button onclick="play()" value="play"> <input type=button onclick="setTime()" value="setTime"> <input type=button onclick="pause()" value="pause"> <script> var play=function() { document.getElementById("video1").play(); } var setTime=function() { document.getElementById("video1").currentTime=2; } var pause=function() { document.getElementById("video1").pause(); } </script> </body> </html> Using Chrome, if you Wait for the video to download for a bit (until the progress bar is about 10% in) Press setTime - you should notice the time jump to 2 seconds press play ...the video will start at 2 seconds in. But if I download the webm file in the source src to my local webserver, and change src to point locally: <source src="chrome_japan.webm" type='video/webm; codecs="vp8, vorbis"'/> ...then setting currentTime is complete ignored. No errors are showing in the developer tools console. Now, my webserver is serving this with mime type "video/webm", but it will be served like any old file -- not streamed. Do I need a webserver that streams in some specific way? What else could be at fault here? Note: The webserver is a proprietary platform and won't have any of the same exact settings or controls one might expect of Tomcat or some other commonly used webserver, though there may be other ways to achieve the same effect.

Can't get my object to point at the mouse.

- by melignus

I'm using a combination of SDL and OpenGL in a sort of crash course project to teach myself how this all works. I'm really only interested in OpenGL as a way to use acceleration in 2D games so I just need this to work in a 2D plane. I have been having a lot of problems today with my current issue, I would like an object to point towards the mouse while the mouse button is clicked and then of course stay pointing in that direction after the mouse is lifted. void Square::handle_input() { //If a key was pressed if( event.type == SDL_KEYDOWN ) { //Adjust the velocity switch( event.key.keysym.sym ) { case SDLK_UP: upUp = false; yVel = -1; break; case SDLK_DOWN: downUp = false; yVel = 1; break; case SDLK_LEFT: leftUp = false; xVel = -1; break; case SDLK_RIGHT: rightUp = false; xVel = 1; break; case SDLK_w: wUp = false; sAng = 1; break; case SDLK_s: sUp = false; sAng = -1; break; } } //If a key was released else if( event.type == SDL_KEYUP ) { //Adjust the velocity switch( event.key.keysym.sym ) { case SDLK_UP: upUp = true; yVel = 0; break; case SDLK_DOWN: downUp = true; yVel = 0; break; case SDLK_LEFT: leftUp = true; xVel = 0; break; case SDLK_RIGHT: rightUp = true; xVel = 0; break; case SDLK_w: wUp = true; sAng = 0; break; case SDLK_s: sUp = true; sAng = 0; break; } } //If a mouse button was pressed if( event.type == SDL_MOUSEBUTTONDOWN ) { switch ( event.type ) { case SDL_MOUSEBUTTONDOWN: mouseUp = false; mousex == event.button.x; mousey == event.button.y; break; case SDL_MOUSEBUTTONUP: mouseUp = true; break; } } } And then this is called at the end of my Object::Move call which also handles x and y translation if (!mouseUp) { xVect = mousex - x; yVect = mousey - y; radAng = atan2 ( mousey - y, mousex - x ); sAng = radAng * 180 / 3.1415926l; } Right now when I click the object turns and faces down to the bottom left but then no longer changes direction. I'd really appreciate any help I could get here. I'm guessing there might be an issue here with state versus polled events but from all the tutorials that I've been through I was pretty sure I had fixed that. I've just hit a wall and I need some advice!

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.

C++ Virtual Constructor, without clone()

- by Julien L.

I want to perform "deep copies" of an STL container of pointers to polymorphic classes. I know about the Prototype design pattern, implemented by means of the Virtual Ctor Idiom, as explained in the C++ FAQ Lite, Item 20.8. It is simple and straightforward: struct ABC // Abstract Base Class { virtual ~ABC() {} virtual ABC * clone() = 0; }; struct D1 : public ABC { virtual D1 * clone() { return new D1( *this ); } // Covariant Return Type }; A deep copy is then: for( i = 0; i < oldVector.size(); ++i ) newVector.push_back( oldVector[i]->clone() ); Drawbacks As Andrei Alexandrescu states it: The clone() implementation must follow the same pattern in all derived classes; in spite of its repetitive structure, there is no reasonable way to automate defining the clone() member function (beyond macros, that is). Moreover, clients of ABC can possibly do something bad. (I mean, nothing prevents clients to do something bad, so, it will happen.) Better design? My question is: is there another way to make an abstract base class clonable without requiring derived classes to write clone-related code? (Helper class? Templates?) Following is my context. Hopefully, it will help understanding my question. I am designing a class hierarchy to perform operations on a class Image: struct ImgOp { virtual ~ImgOp() {} bool run( Image & ) = 0; }; Image operations are user-defined: clients of the class hierarchy will implement their own classes derived from ImgOp: struct CheckImageSize : public ImgOp { std::size_t w, h; bool run( Image &i ) { return w==i.width() && h==i.height(); } }; struct CheckImageResolution; struct RotateImage; ... Multiple operations can be performed sequentially on an image: bool do_operations( std::vector< ImgOp* > v, Image &i ) { std::for_each( v.begin(), v.end(), /* bind2nd(mem_fun(&ImgOp::run), i ...) don't remember syntax */ ); } int main( ... ) { std::vector< ImgOp* > v; v.push_back( new CheckImageSize ); v.push_back( new CheckImageResolution ); v.push_back( new RotateImage ); Image i; do_operations( v, i ); } If there are multiple images, the set can be split and shared over several threads. To ensure "thread-safety", each thread must have its own copy of all operation objects contained in v -- v becomes a prototype to be deep copied in each thread.

Using one data source across multiple views in Kendo UI SPA

- by user3731783

I am trying to build a Kendo UI SPA. I have two views. View 1 (appListView) shows Application Details in a grid and view 2 (activityView) will have a dropdown for application names and a grid that shows the activity for selected application As I am loading all the application details on the loading of view 1, I would like to re-use those details to populate the dropdown on view 2. Please see my code below. Everything works fine but when I go to View 2 it makes a call to the service again to get application details. I would like to use the existing data if it is already loaded and if the uses comes to view 2 directly then it should get application data also. I am not sure what I am missing in the code. View Markup: <script id="appListView" type="text/x-kendo-template"> <h3 data-bind="html: displayName"></h3> <div data-role="grid" data-editable="{'mode':'popup'}" data-bind="source: items" data-columns="[ {'field': 'Name'}, {'field': 'ContactEmail','title':'Contact Email'} ]"> </div> </script> <script id="" type="text\x-kendo-template"> <div> Activity for Application   <input name="AppName" data-role="dropdownlist" data-source="appsModel.items" data-text-field="Name" data-value-field="Id" data-option-label="Choose an application name" style="width:250px;" /> </div> <div id="Activities" data-role="grid" data-bind="source: items" data-auto-bind="false" data-columns="[ {'field': 'Domain','title':'Domain'}, {'field': 'ActivityType','title':'Activity Type'} ]"> </div> </script> js with DataSource and View Model: //data sources var applications = new kendo.data.DataSource({ schema: { model: { id: "Id" } }, serverFiltering : true, transport: { read: { url: '/api/App', dataType: 'json', type:'GET' } } }); var activities = new kendo.data.DataSource({ schema: { model: { id: "Id" } }, transport: { read: { url: '/api/Activity', dataType: 'json', type: 'GET' }, parameterMap: function (data, type) { if (type == "read") { return 'appId=' + $("#AppName").val() ; } } } }); //Models var appsModel = kendo.observable({ items: applications, displayName: 'My Applications' }); var activityModel = kendo.observable({ items: activities, onAppChange: function(t){ $("#Activities").data("kendoGrid").dataSource.read(); }, dispayName: 'Application Activities' }); //views var layout = new kendo.Layout("layout-template"); var appListView = new kendo.View("appListView", { model: appsModel }); var activityView = new kendo.View("activityView", { model: activityModel }); Thank you for taking time to read this long question.

CSS Collapsing/Hiding divs with no data in <span>

- by Chance

I am trying to display an address which includes the following information: Title, division, address1, address2, town/state/zip, and country (5 seperate lines worth of data). The problem is sometimes the company may only have the title, address1, and town/state/zip yet other times it may be all but address2. This is determined upon a db record request server side. Therefore how can I make my output look proper when some of my labels will be blank? I would like div's that contain an empty span to be essentially collapsed/removed. My only idea of how was to use jquery and a selector to find all divs with blank spans (since thats all an asp.net label really is) and then remove those divs however this seems like such bad form. Is there any way to do this with css? Possible Code would be something like: $('span:empty:only-child').parent('div').remove(); Picture Examples (Ignore spacing/indentation issues which I will fix) Missing Division, Address2, and Country All Possible Fields The Html <asp:Label runat="server" ID="lblBillingAddressHeader" CssClass="lblBillingAddressHeader" Text="Billing Address:" /> <div style="position:relative; top:150px; left: 113px;"> <div class="test"> <asp:Label runat="server" ID="lblBillingDivision" CssClass="lblBillingShippingDivisionFont" /> </div> <div class="test"> <asp:Label runat="server" ID="lblBillingAddress" CssClass="lblBillingShippingFont" /> </div> <div class="test"> <asp:Label runat="server" ID="lblBillingAddress2" CssClass="lblBillingShippingFont" /> </div> <div class="test"> <asp:Label runat="server" ID="lblBillingAddress3" CssClass="lblBillingShippingFont" /> </div> <div class="test"> <asp:Label runat="server" ID="lblBillingAddress4" CssClass="lblBillingShippingFont" /> </div> </div> The CSS .test { position: relative; top: 0px; left: 0px; height: 12px; width: 300px; } .lblBillingShippingDivisionFont { font-size: small; font-weight: bold; } .lblBillingShippingFont { font-size: 10.6px; }

Insane CPU usage in QT 5.0

- by GravityScore

I'm having trouble using the QT framework, particularly with the paintEvent of QWidget. I have a QWidget set up, and am overriding the paintEvent of it. I need to render a bunch of rectangles (grid system), 51 by 19, leading to 969 rectangles being drawn. This is done in a for loop. Then I also need to draw an image on each on of these grids. The QWidget is added to a QMainWindow, which is shown. This works nicely, but it's using up 47% of CPU per window open! And I want to allow the user to open multiple windows like this, likey having 3-4 open at a time, which puts the CPU close to 150%. Why does this happen? Here is the paintEvent contents. The JNI calls don't cause the CPU usage, commenting them out doesn't lower it, but commenting out the p.fillRect and Renderer::renderString (which draws the image) lowers the CPU to about 5%. // Background QPainter p(this); p.fillRect(0, 0, this->width(), this->height(), QBrush(QColor(0, 0, 0))); // Lines for (int y = 0; y < Global::terminalHeight; y++) { // Line and color method ID jmethodID lineid = Manager::jenv->GetMethodID(this->javaClass, "getLine", "(I)Ljava/lang/String;"); error(); jmethodID colorid = Manager::jenv->GetMethodID(this->javaClass, "getColorLine", "(I)Ljava/lang/String;"); error(); // Values jstring jl = (jstring) Manager::jenv->CallObjectMethod(this->javaObject, lineid, jint(y)); error(); jstring cjl = (jstring) Manager::jenv->CallObjectMethod(this->javaObject, colorid, jint(y)); error(); // Convert to C values const char *l = Manager::jenv->GetStringUTFChars(jl, 0); const char *cl = Manager::jenv->GetStringUTFChars(cjl, 0); QString line = QString(l); QString color = QString(cl); // Render line for (int x = 0; x < Global::terminalWidth; x++) { QColor bg = Renderer::colorForHex(color.mid(x + color.length() / 2, 1)); // Cell location on widget int cellx = x * Global::cellWidth + Global::xoffset; int celly = y * Global::cellHeight + Global::yoffset; // Background p.fillRect(cellx, celly, Global::cellWidth, Global::cellHeight, QBrush(bg)); // String // Renders the image to the grid Renderer::renderString(p, tc, text, cellx, celly); } // Release Manager::jenv->ReleaseStringUTFChars(jl, l); Manager::jenv->ReleaseStringUTFChars(cjl, cl); }

invite friends in a dialog in a Facebook application

- by Shani1351

I'm trying to create a Facebook application that displays a friend invite dialog within the application using Facebook's Javascript API (FB.ui). To do that I followed this tutorial I have two problems : The action url I've put in the request-form is "http://apps.facebook.com/appname/post_invite.php" but I see that the iframe source after the post is "http://mydomain.com/post_invite.php" and when this iframe tries to do : parent.closeInviteWidget(); I get an error saying : "Permission denied for < http: //mydomain.com (document.domain has not been set) to get property Window.closeInviteWidget from < http:// apps.facebook.com (document.domain=< http:// facebook.com)." The skip button inside the request-form opens the action url in a new window (new browser tab) and not post to itself like the invite button. How can I fix those problems? -------------------- UPDATE : -------------------------------- I've tried to do what ifaour said and changed the code to : function inviteFriends(user_name, category_id, category_name) { url = appBaseUrl + "/index.php?category_id=" + category_id; req = "<fb:req-choice url='" + url + "' label='Authorize My Application' />"; content = user_name + " opened a new category called " + category_name + ". " + req; action = 'post_invite.php'; fbmi_text = '<fb:request-form action="' + action + '" target="_self" method="post" invite="true" type="Invite" content="' + content + '" <fb:multi-friend-selector showborder="false" actiontext="Invite yor friends" email_invite="false" import_external_friends="false" /> </fb:request-form>'; FB.ui({ method:'fbml.dialog', width:'750px', fbml:fbmi_text }); } When I use FireBug and look at the invite form it looks like this: <form id="req_form_4d20682f73ddb6e71722794" content="I've opened a new category called dsfsd. <fb:req-choice url='http://apps.facebook.com/appname/index.php?category_id=60' label='Authorize My Application' /> type="Invite" invite="true" method="post" target="_self" action="http://apps.facebook.com/appname/post_invite.php"> ... </form> But I still get the same error : Permission denied for <http://mydomain.com> (document.domain has not been set) to get property Window.closeInviteWidget from <http://apps.facebook.com> (document.domain=<http://facebook.com>)...

Why is this unwanted ">" character being displayed when displaying this PHP document in a browser?

- by CT

This page takes an asset id from $_GET of the url and displays some info about the asset after querying a mysql database. When I view the page in my browser there is an unwanted "" character within the page and I have no idea why. I've commented where it appears. It appears before the < table create tag right afterward. The < table tag was originally outside the php script section but I threw it in to see if it made a difference. It did not. Thank you all. I am viewing the page in Firefox.

Google Maps and Json structure

- by mark

I found a great script to plot markers on Google Maps. It uses an Json file to laod it. The problem is I don't know what the structure looks like in this case. Can you help? function loadMarkers() { var bounds = map.getBounds(); var zoomLevel = map.getZoom(); $.post("/gmaps/markers/index.php", {zoom: zoomLevel, swLat: bounds.getSouthWest().lat(), swLon: bounds.getSouthWest().lng(), neLat: bounds.getNorthEast().lat(), neLon: bounds.getNorthEast().lng()}, function(data) { processMarkers(data, _smallMarkerSize); }, "json" ); } function processMarkers(webcams, markerSize) { var marker = null; var markersInView = new Array(); var idsInView = new Array(); // Loop through the new webcams for (var i = 0; i < webcams.length; i++) { var idx = markers.indexOf(webcams[i].id); if (idx == -1) { var info_html = "<table class='infowindow'>"; info_html += "<tr><td class='img'>"; info_html += "<img src='" + webcams[i].smallimg + "' /><td>"; info_html += "<td><p><b>" + webcams[i].loc + "</b>"; info_html += "<br /><a href='/webcam/" + webcams[i].url + "' target='_blank'>Show webcam</a></p></td></tr>"; info_html += "</table>"; marker = new WebcamMarker(new GLatLng(webcams[i].latitude, webcams[i].longitude), {image: "" + webcams[i].smallimg + "", height: markerSize, width: markerSize}); marker.myhtml = info_html; map.addOverlay(marker); markersInView[webcams[i].id] = marker; } else { markersInView[webcams[i].id] = markers[webcams[i].id]; } idsInView.push(webcams[i].id); } // Now remove the markers outside of the viewport for (var i = 0; i < webcamids.length; i++) { var idx = markersInView.indexOf(webcamids[i]); if (idx == -1) { marker = markers[webcamids[i]]; map.removeOverlay(marker); } } markers = markersInView; webcamids = idsInView; }

I am sorry for the non-informative title. exstatus <- structure(list(org = structure(c(2L, 1L, 7L, 3L, 6L, 2L, 2L, 7L, 2L, 1L, 2L, 2L, 4L, 2L, 2L, 2L, 2L, 2L, 2L, 1L, 8L, 4L, 2L, 2L, 5L, 7L, 8L, 6L, 2L, 7L, 2L, 2L, 7L, 2L, 2L, 2L, 2L, 4L, 2L, 2L, 1L, 2L, 2L, 7L, 2L, 7L, 2L, 4L, 7L, 2L, 4L, 2L, 2L, 2L, 7L, 7L, 2L, 7L, 2L, 7L, 1L, 7L, 5L, 2L, 2L, 1L, 7L, 3L, 5L, 3L, 2L, 2L, 2L, 7L, 4L, 2L, 7L, 2L, 4L, 2L, 2L, 2L, 4L, 6L, 2L, 4L, 4L, 7L, 2L, 2L, 2L, 7L, 6L, 2L, 2L, 1L, 2L, 2L, 4L, 1L, 2L, 2L, 2L, 2L, 2L, 2L, 2L, 2L, 2L, 1L, 6L, 2L, 7L, 7L, 2L, 7L, 8L, 7L, 8L, 6L, 7L, 2L, 2L, 2L, 7L, 2L, 7L, 2L, 7L, 2L, 7L, 2L, 4L, 2L, 7L, 2L, 4L, 8L, 2L, 3L, 4L, 2L, 7L, 3L, 8L, 8L, 6L, 2L, 2L, 2L, 7L, 7L, 7L, 7L, 2L, 2L, 2L, 2L, 7L, 2L, 4L, 7L, 7L, 8L, 2L, 7L, 2L, 2L, 2L, 2L, 1L, 7L, 7L, 2L, 1L, 7L, 2L, 7L, 7L, 2L, 2L, 7L, 2L, 2L, 7L, 7L, 2L, 7L, 2L, 7L, 5L, 2L), .Label = c("gl", "il", "gm", "im", "gk", "ik", "tv", "tu"), class = "factor"), art = structure(c(2L, 1L, 3L, 1L, 2L, 2L, 2L, 3L, 2L, 1L, 2L, 2L, 2L, 2L, 2L, 2L, 2L, 2L, 2L, 1L, 3L, 2L, 2L, 2L, 1L, 3L, 3L, 2L, 2L, 3L, 2L, 2L, 3L, 2L, 2L, 2L, 2L, 2L, 2L, 2L, 1L, 2L, 2L, 3L, 2L, 3L, 2L, 2L, 3L, 2L, 2L, 2L, 2L, 2L, 3L, 3L, 2L, 3L, 2L, 3L, 1L, 3L, 1L, 2L, 2L, 1L, 3L, 1L, 1L, 1L, 2L, 2L, 2L, 3L, 2L, 2L, 3L, 2L, 2L, 2L, 2L, 2L, 2L, 2L, 2L, 2L, 2L, 3L, 2L, 2L, 2L, 3L, 2L, 2L, 2L, 1L, 2L, 2L, 2L, 1L, 2L, 2L, 2L, 2L, 2L, 2L, 2L, 2L, 2L, 1L, 2L, 2L, 3L, 3L, 2L, 3L, 3L, 3L, 3L, 2L, 3L, 2L, 2L, 2L, 3L, 2L, 3L, 2L, 3L, 2L, 3L, 2L, 2L, 2L, 3L, 2L, 2L, 3L, 2L, 1L, 2L, 2L, 3L, 1L, 3L, 3L, 2L, 2L, 2L, 2L, 3L, 3L, 3L, 3L, 2L, 2L, 2L, 2L, 3L, 2L, 2L, 3L, 3L, 3L, 2L, 3L, 2L, 2L, 2L, 2L, 1L, 3L, 3L, 2L, 1L, 3L, 2L, 3L, 3L, 2L, 2L, 3L, 2L, 2L, 3L, 3L, 2L, 3L, 2L, 3L, 1L, 2L), .Label = c("Finish", "Attending", "Something"), class = "factor"), type = structure(c(2L, 2L, 5L, 3L, 1L, 2L, 2L, 5L, 2L, 2L, 2L, 2L, 3L, 2L, 2L, 2L, 2L, 2L, 2L, 2L, 4L, 3L, 2L, 2L, 1L, 5L, 4L, 1L, 2L, 5L, 2L, 2L, 5L, 2L, 2L, 2L, 2L, 3L, 2L, 2L, 2L, 2L, 2L, 5L, 2L, 5L, 2L, 3L, 5L, 2L, 3L, 2L, 2L, 2L, 5L, 5L, 2L, 5L, 2L, 5L, 2L, 5L, 1L, 2L, 2L, 2L, 5L, 3L, 1L, 3L, 2L, 2L, 2L, 5L, 3L, 2L, 5L, 2L, 3L, 2L, 2L, 2L, 3L, 1L, 2L, 3L, 3L, 5L, 2L, 2L, 2L, 5L, 1L, 2L, 2L, 2L, 2L, 2L, 3L, 2L, 2L, 2L, 2L, 2L, 2L, 2L, 2L, 2L, 2L, 2L, 1L, 2L, 5L, 5L, 2L, 5L, 4L, 5L, 4L, 1L, 5L, 2L, 2L, 2L, 5L, 2L, 5L, 2L, 5L, 2L, 5L, 2L, 3L, 2L, 5L, 2L, 3L, 4L, 2L, 3L, 3L, 2L, 5L, 3L, 4L, 4L, 1L, 2L, 2L, 2L, 5L, 5L, 5L, 5L, 2L, 2L, 2L, 2L, 5L, 2L, 3L, 5L, 5L, 4L, 2L, 5L, 2L, 2L, 2L, 2L, 2L, 5L, 5L, 2L, 2L, 5L, 2L, 5L, 5L, 2L, 2L, 5L, 2L, 2L, 5L, 5L, 2L, 5L, 2L, 5L, 1L, 2L), .Label = c("short", "long", "between", "young", "old"), class = "factor")), .Names = c("org", "art", "type"), row.names = c(NA, -192L), class = "data.frame") and then the plot ggplot(exstatus, aes(x=type, fill=art))+ geom_bar(aes(y=..count../sum(..count..)),position="dodge") The problem is that the two rightmost bars ("young", "old") are too thick - "something" takes up the whole width - whcih is not what I intended. I am sorry that I can not explain it better.
