  • Emberjs bindAttr inside of #each

    - by Andrej Kaurin
    Code for view is Ember.View.extend({ template: Ember.Handlebars.compile(html), // html is in string content: function() { return [ { Title: "Dashboard", ID: "dashboard" }, { Title: "Invoices", ID: "invoices" }, { Title: "Expenses", ID: "expenses" }, { Title: "People", ID: "people" }, { Title: "Reports", ID: "reports" }, { Title: "Settings", ID: "settings" } ]}, iconClass: "icon icon-dashboard" }); Template (show above as "html") looks like this: <ul> {{#each link in content}} <li> <a> <span class="icon" {{bindAttr class="iconClass"}}></span> <span class="title">{{link.Title}}</span> </a> </li> {{/each}} </ul> Am I doing something wrong with scope or?

  • bluetooth file send.

    i'm new to bluetooth development and i found the 32netfeet . Right now i'm able to search for bluetooth devices nearby and connect to them but how do i send a file e.g SendTest.txt? I tried buttonclick event using the OBEX but i don't understand this is my example code: using InTheHand.Net; using InTheHand.Net.Sockets; using InTheHand.Net.Bluetooth; namespace BluetoothIntheHand { public partial class Form2 : Form { private Guid service = BluetoothService.DialupNetworking; private BluetoothClient bluetoothClient; public Form2() { InitializeComponent(); } private void btnSearch_Click(object sender, EventArgs e) { BluetoothRadio.PrimaryRadio.Mode = RadioMode.Discoverable; BluetoothRadio myRadio = BluetoothRadio.PrimaryRadio; lblSearch.Text = "" + myRadio.LocalAddress.ToString(); bluetoothClient = new BluetoothClient(); Cursor.Current = Cursors.WaitCursor; BluetoothDeviceInfo[] bluetoothDeviceInfo = { }; bluetoothDeviceInfo = bluetoothClient.DiscoverDevices(10); comboBox1.DataSource = bluetoothDeviceInfo; comboBox1.DisplayMember = "DeviceName"; comboBox1.ValueMember = "DeviceAddress"; comboBox1.Focus(); Cursor.Current = Cursors.Default; } private void btnConnect_Click(object sender, EventArgs e) { if (comboBox1.SelectedValue != null) { try { bluetoothClient.Connect(new BluetoothEndPoint((BluetoothAddress)comboBox1.SelectedValue, service)); MessageBox.Show("Connected"); } catch (Exception ex) { MessageBox.Show(ex.Message); } } } private void btnSend_Click(object sender, EventArgs e) { bluetoothClient.Connect(new BluetoothEndPoint((BluetoothAddress)comboBox1.SelectedValue, service)); String addr = "112233445566"; Uri uri = new Uri("obex://"+@"SendTest.txt"); ObexWebRequest req= new ObexWebRequest(uri); ObexWebResponse rsp; } I found the guide but don't really know how to convert to C# ' The host part of the URI is the device address, e.g. IrDAAddress.ToString(), ' and the file part is the OBEX object name.

  • Problem with persisting inteface collection at design time in winforms, .net

    - by Jules
    The easiest way to explain this problem is to show you some code: Public Interface IAmAnnoyed End Interface Public Class IAmAnnoyedCollection Inherits ObjectModel.Collection(Of IAmAnnoyed) End Class Public Class Anger Implements IAmAnnoyed End Class Public Class MyButton Inherits Button Private _Annoyance As IAmAnnoyedCollection <DesignerSerializationVisibility(DesignerSerializationVisibility.Content)> _ Public ReadOnly Property Annoyance() As IAmAnnoyedCollection Get Return _Annoyance End Get End Property Private _InternalAnger As Anger <DesignerSerializationVisibility(DesignerSerializationVisibility.Content)> _ Public ReadOnly Property InternalAnger() As Anger Get Return Me._InternalAnger End Get End Property Public Sub New() Me._Annoyance = New IAmAnnoyedCollection Me._InternalAnger = New Anger Me._Annoyance.Add(Me._InternalAnger) End Sub End Class And this is the code that the designer generates: Private Sub InitializeComponent() Dim Anger1 As Anger = New Anger Me.MyButton1 = New MyButton ' 'MyButton1 ' Me.MyButton1.Annoyance.Add(Anger1) // Should be: Me.MyButton1.Annoyance.Add(Me.MyButton1.InternalAnger) ' 'Form1 ' Me.Controls.Add(Me.MyButton1) End Sub I've added a comment to the above to show how the code should have been generated. Now, if I dispense with the interface and just have a collection of Anger, then it persists correctly. Any ideas?

  • jQuery ajax() function is ignoring dataType parameter in Firefox

    - by ccleve
    I'm trying to use jQuery.ajax() to fetch some html, but Firefox is giving me a "junk after document element" error message. As explained here and here the problem seems to be that Firefox is expecting XML from the server, and when it doesn't parse correctly it throws the error. Here's my ajax code: jQuery.ajax({ url: name, dataType: "html", success: function(result) { console.log(result); }, error: function (jqXHR, textStatus, errorThrown) { console.log(errorThrown); } }); The server returns the html with these response headers: Accept-Ranges bytes Content-Length 2957 Last-Modified Tue, 02 Jul 2013 16:16:59 GMT Note that there's no content-type header. I'm sure that adding one would solve the problem, but that's not an option. The real problem is that Firefox appears to be ignoring the dataType: parameter in the ajax call. I've also tried adding contentType: and accepts: parameters, but it doesn't help. What am I missing here? How do I force Firefox to process the response as plain text?

  • FIFA official website design and development

    - by Morron
    Hi, I'm just curious about design and development of official FIFA website. What is the programming language being used to build the site? What is the development methodology they are using? I used Firebug to look around the site.Here's sth I found: HTTP/1.1 200 OK Cache-Control: no-store, no-cache, must-revalidate, private Content-Type: text/html Server: Microsoft-IIS/7.0 x-ua-compatible: IE=EmulateIE7 Vary: Accept-Encoding Content-Length: 8320 Date: Tue, 15 Jun 2010 17:54:19 GMT Connection: keep-alive According to that, I think they use IIS 7 to run the site but I'm not sure what programming language they are using. Any comment is a drop of water in the glass.

  • How to implement SCORM in Objective C

    - by iranjan
    Hey, Do you know how to implement SCORM (Sharable Content Object Reference Model) in Objective C for eLearning content? Let me explain you what exactly I am looking for. I have one MCQ (multiple choice question) application which has 4 questions. On attempting each question I want my application to interact with a SCORM compatible server with result (whether the user has attempted correct one or not). The communication channel should be to and fro. May be at the end of the MCQ I want to show result which will come from the server with some calculations*(like Score : 85% number of attempts : 16 average score:16.7% etc.)*. How should I go about it? Please guide if you have already achieved it regards Ranjan.

  • clicktale.com alternative that works with https and ajax

    - by Alexey Ivanov
    I need to record user's actions on site for analytics purposes. The way clicktale.com doing it is just fine. But unfortunately it have problems with working over https and recording ajax events. Is there some service or script/library that I can host that can do this task? Non-free one's are ok to. Clarification: ClickTale function that I want to reproduce is recording of separate user sessions and their replay. So you can see video of all user's interactions with page: There he clicks first, which links opens, etc. Usually such services replay user's actions buy reproducing them with javascript (and here comes ajax problem: external sites can't use ajax because of cross-domain scripting). So I'm looking for a tool (possibly script that I host on site to allow cross-domain scripting) that can record ajax blocks actions.

  • Insert default value if input-text is deleted

    - by Kim Andersen
    Hi all I have the following piece of jQuery code: $(".SearchForm input:text").each(function(){ /* Sets the current value as the defaultvalue attribute */ if(allowedDefaults.indexOf($(this).val()) > 0 || $(this).val() == "") { $(this).attr("defaultvalue", $(this).val()); $(this).css("color","#9d9d9d"); /* Onfocus, if default value clear the field */ $(this).focus(function(){ if($(this).val() == $(this).attr("defaultvalue")) { $(this).val(""); $(this).css("color","#4c4c4c"); } }); /* Onblur, if empty, insert defaultvalue */ $(this).blur(function(){ alert("ud"); if($(this).val() == "") { $(this).val($(this).attr("defaultvalue")); $(this).css("color","#9d9d9d"); }else { $(this).removeClass("ignore"); } }); } }); I use this code to insert some default text into some of my input fields, when nothing else is typed in. This means that when a user sees my search-form, the defaultvalues will be set as an attribute on the input-field, and this will be the value that is shown. When a user clicks inside of the input field, the default value will be removed. When the user sees an input field at first is looks like this: <input type="text" value="" defaultvalue="From" /> This works just fine, but I have a big challenge. If a user have posted the form, and something is entered into one of the fields, then I can't show the default value in the field, if the user deletes the text from the input field. This is happening because the value of the text-field is still containing something, even when the user deletes the content. So my problem is how to show the default value when the form is submitted, and the user then removes the typed in content? When the form is submitted the input looks like this, and keeps looking like this until the form is submitted again: <input type="text" value="someValue" defaultvalue="From" /> So I need to show the default value in the input-field right after the user have deleted the content in the field, and removed the focus from the field. Does everyone understand what my problem is? Otherwise just ask, I have struggled with this one for quite some times now, so any help will be greatly appreciated. Thanks in advance, Kim Andersen

  • iGoogle Stack Overflow Gadget [closed]

    Since SO's question database is becoming an excellent first point of call for finding answers to coding problems, some people (like me) might like to be able to fire up searches from their iGoogle home page, among the other searches you might launch from there. I've created a very simple gadget to do this, and put the source below. My hope is that this might provide a foundation on which community members with better ideas for performing this function, or ideas for enhancing it, can update it.

  • Rails 2.x http basic authentication

  • How to use Broadcast Receiver in different Applications in Android?

    - by Sebi
    Hi I have here two applications in two different projects in eclipse. One application (A) defines an activity (A1) which is started first. Then i start from this activity the second activity (B1) in the second project (B). This works fine. I start it the following way: Intent intent = new Intent("pacman.intent.action.Launch"); intent.addFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP); startActivity(intent); Now i want to send intents bewtween the two activities by using broadcast receivers. In activity A1 i send the intents the following way: Intent intent = new Intent("pacman.intent.action.BROADCAST"); intent.putExtra("message","Wake up."); sendBroadcast(intent); The part of the manifest file in activity A1 that is responsible for this broadcast is the following: <activity android:name="ch.ifi.csg.games4blue.games.pacman.controller.PacmanGame" android:label="@string/app_name"> <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> <intent-filter> <action android:name="android.intent.action.BROADCAST" /> </intent-filter> </activity> In the receiving activity, I define the receiver the following way in the manifest file: <application android:icon="@drawable/icon" android:label="@string/app_name"> <activity android:name=".PacmanGame" android:label="@string/app_name" android:screenOrientation="portrait"> <intent-filter> <action android:name="pacman.intent.action.Launch" /> <category android:name="android.intent.category.DEFAULT" /> </intent-filter> <receiver android:name="ch.ifi.csg.games4blue.games.pacman.controller.MsgListener" /> </activity> </application> The class message listener is implemented this way: public class MsgListener extends BroadcastReceiver { /* (non-Javadoc) * @see android.content.BroadcastReceiver#onReceive(android.content.Context, android.content.Intent) */ @Override public void onReceive(Context context, Intent intent) { System.out.println("Message at Pacman received!"); } } Unfortunately, the message is never received. Although the method in activity A1 is called, i never receive an intent in B1. Any hints how to solve this? Thanks a lot!

  • Rails + AMcharts (with export image php script) - PHP script converted to controller?

    - by Elliot
    Hey Guys, This one might be a little confusing. I'm using AMCharts with rails. Amcharts comes with a PHP script to export images called "export.php" I'm trying to figure out how to take the code in export.php and put it into a controller. Here is the code: <?php // amcharts.com export to image utility // set image type (gif/png/jpeg) $imgtype = 'jpeg'; // set image quality (from 0 to 100, not applicable to gif) $imgquality = 100; // get data from $_POST or $_GET ? $data = &$_POST; // get image dimensions $width = (int) $data['width']; $height = (int) $data['height']; // create image object $img = imagecreatetruecolor($width, $height); // populate image with pixels for ($y = 0; $y < $height; $y++) { // innitialize $x = 0; // get row data $row = explode(',', $data['r'.$y]); // place row pixels $cnt = sizeof($row); for ($r = 0; $r < $cnt; $r++) { // get pixel(s) data $pixel = explode(':', $row[$r]); // get color $pixel[0] = str_pad($pixel[0], 6, '0', STR_PAD_LEFT); $cr = hexdec(substr($pixel[0], 0, 2)); $cg = hexdec(substr($pixel[0], 2, 2)); $cb = hexdec(substr($pixel[0], 4, 2)); // allocate color $color = imagecolorallocate($img, $cr, $cg, $cb); // place repeating pixels $repeat = isset($pixel[1]) ? (int) $pixel[1] : 1; for ($c = 0; $c < $repeat; $c++) { // place pixel imagesetpixel($img, $x, $y, $color); // iterate column $x++; } } } // set proper content type header('Content-type: image/'.$imgtype); header('Content-Disposition: attachment; filename="chart.'.$imgtype.'"'); // stream image $function = 'image'.$imgtype; if ($imgtype == 'gif') { $function($img); } else { $function($img, null, $imgquality); } // destroy imagedestroy($img); ?>

  • Java List use through use of JSTL <c:forEach>

    - by Mark Lewis
    Hello If I have a JSF backing bean return an object of type ArrayList, I should be able to use to iterate over the elements in the list. Each element contains a map and although the question of how to access the map content through JSTL has been answered here, if I pass an array of such maps, I can't find how to iterate over them and still access the map content using JSTL. There's documentation which refers to simple iterators but not to those whose items are themselves maps. BalusC, I'm not trying to force the issue, just that I've been looking at this all day, and still cannot seem to be able to output the contents of my data structure through jsp (only on the console). This as a separate question still has merit. If anyone can give me a simple example of how a java List is iterated over in JSP I'd be massively appreciative. Mark

  • Will client side performance improve if images/scripts/styles on different subdomains?

    - by Andrey
    Hi, I have a domain specifically for static content, so cookies don't travel along with requests to images/scripts/css. Now, I think I've read somewhere that most browsers only open one download thread for each domain/subdomain, so different static content can't be downloaded in parallel if on the same domain. Will it make difference for browsers if i place scripts in script.mycdn.com, styles in css.mycdn.com and images in images.mycdn.com? Will it allow to let browser download images at the same time as scripts and styles? mycdn.com is of course a made up name :) Thanks! Andrey

  • CSS sprites navigation and User with image disabled.....

    - by metal-gear-solid
    I made a css menu with css sprites but the problem is with sprite we don't use inline image we use in background only so if images are disabled in browser then nothing will show . any solution for this ? For example : See this menu and turn off images : http://line25.com/wp-content/uploads/2009/css-menu/demo/demo.html (it will not be seen if images are disabled in browser) this menu is against on this quote Ensure your website works with images disabled Creating a site that relies too heavily on images is never a good idea. Although almost a thing of the past, there are still users who run at very low internet speeds. Also, if a user needs to—for whatever reason—disable images, can they still access all the content they need to? http://csswizardry.com/quick-tips/#tip-02 Shouldn't we use this type of navigation.

  • Throwing an exception from a BackgroundWorker which calls an async. method (Webrequest)

    - by mrbamboo
    Hi, My main application creates a new BackgroundWorker X the DoWork event handler of X calls a method Y of my controller. This method creates the WebRequest (async.) instance and the callback using AsyncCallback. When the response arrives the callback method Z gets called and the content will be analyzed. It can happen that the response has an unwanted content. At that moment callback Z will throw an exception. I want to catch this exception in my main application.
