  • Issues with cross-domain uploading

    - by meder
    I'm using a django plugin called django-filebrowser which utilizes uploadify. The issue I'm having is that I'm hosting uploadify.swf on a remote static media server, whereas my admin area is on my django server. At first, the browse button wouldn't invoke my browser's upload. I fixed this by modifying the sameScriptAccess to always instead of sameDomain. Now the progress bar doesn't move at all, I probably have to enable some server setting for cross domain file uploading, or most likely actually host a separate upload script on my media server. I thought I could solve this by adding a crossdomain.xml to enable any site at the root of both servers, but that doesn't seem to solve it. $(document).ready(function() { $('#id_file').uploadify({ 'uploader' : 'http://media.site.com:8080/admin/filebrowser/uploadify/uploadify.swf', 'script' : '/admin/filebrowser/upload_file/', 'scriptData' : {'session_key': '...'}, 'checkScript' : '/admin/filebrowser/check_file/', 'cancelImg' : 'http://media.site.com:8080/admin/filebrowser/uploadify/cancel.png', 'auto' : false, 'folder' : '', 'multi' : true, 'fileDesc' : '*.html;*.py;*.js;*.css;*.jpg;*.jpeg;*.gif;*.png;*.tif;*.tiff;*.mp3;*.mp4;*.wav;*.aiff;*.midi;*.m4p;*.mov;*.wmv;*.mpeg;*.mpg;*.avi;*.rm;*.pdf;*.doc;*.rtf;*.txt;*.xls;*.csv;', 'fileExt' : '*.html;*.py;*.js;*.css;*.jpg;*.jpeg;*.gif;*.png;*.tif;*.tiff;*.mp3;*.mp4;*.wav;*.aiff;*.midi;*.m4p;*.mov;*.wmv;*.mpeg;*.mpg;*.avi;*.rm;*.pdf;*.doc;*.rtf;*.txt;*.xls;*.csv;', 'sizeLimit' : 10485760, 'scriptAccess' : 'always', //'scriptAccess' : 'sameDomain', 'queueSizeLimit' : 50, 'simUploadLimit' : 1, 'width' : 300, 'height' : 30, 'hideButton' : false, 'wmode' : 'transparent', translations : { browseButton: 'BROWSE', error: 'An Error occured', completed: 'Completed', replaceFile: 'Do you want to replace the file', unitKb: 'KB', unitMb: 'MB' } }); $('input:submit').click(function(){ $('#id_file').uploadifyUpload(); return false; }); }); The page I'm viewing this on is http://site.com/admin/filebrowser/browse on port 80.

  • Why unchecked jQuery UI radio button's label appears "checked" after refresh in FF and IE?

    - by Daj pan spokój
    I've got 2 radio buttons with labels: button A is checked by default in HTML (checked="checked"). They're then processed with jQuery UI Radio Button. When I check button B and refresh the page, B's label is displayed as checked (it has CSS ui-state-active class). And A's label is displayed as unchecked, even though it's A button that is actually checked. It happens in Firefox (3) and IE (8). In Chrome (5) it works fine - after refresh A's label is displayed as checked. <input class="ui-helper-hidden-accessible" id="show-all-hotels" name="radio" CHECKED="CHECKED" type="radio"> <label aria-disabled="false" role="button" class="ui-button ui-widget ui-state-default ui-button-text-only ui-corner-left" aria-pressed="false" for="show-all-hotels"> <span class="ui-button-text">All tours</span> </label> <input class="ui-helper-hidden-accessible" id="show-availability" name="radio" type="radio"> <label aria-disabled="false" role="button" aria-pressed="true" class="UI-STATE-ACTIVE ui-button ui-widget ui-state-default ui-button-text-only ui-corner-right" for="show-availability"> <span class="ui-button-text">Only available at</span> </label> Do You know why is it happening and how to make checked button label appear as checked in all browsers?

  • TinyMCE is glitchy in IE8

    - by Force Flow
    I'm using the jQuery version of TinyMCE 3.3.9.3 In firefox, it works fine (10 sec video depicting it in use): http://www.youtube.com/watch?v=TrAE0igfT3I In IE8 (in IE8 standards mode), I can't type or click any buttons. However, if I use ctrl+v to paste, then I can start typing, but the buttons still don't work (a 45 sec video depicting it in use): http://www.youtube.com/watch?v=iBSRlE8D8F4 The jQuery TinyMCE demo on TinyMCE's site works for me in IE8. Here's the init code: $().ready(function(){ function tinymce_focus(){ $('.defaultSkin table.mceLayout').css({'border-color' : '#6478D7'}); $('.defaultSkin table.mceLayout tr.mceFirst td').css({'border-top-color' : '#6478D7'}); $('.defaultSkin table.mceLayout tr.mceLast td').css({'border-bottom-color' : '#6478D7'}); } function tinymce_blur(){ $('.defaultSkin table.mceLayout').css({'border-color' : '#93a6e1'}); $('.defaultSkin table.mceLayout tr.mceFirst td').css({'border-top-color' : '#93a6e1'}); $('.defaultSkin table.mceLayout tr.mceLast td').css({'border-bottom-color' : '#93a6e1'}); } $('textarea.tinymce').tinymce({ script_url : 'JS/tinymce/tiny_mce.js', theme : "advanced", mode : "exact", theme : "advanced", invalid_elements : "b,i,iframe,font,input,textarea,select,button,form,fieldset,legend,script,noscript,object,embed,table,img,a,h1,h2,h3,h4,h5,h6", //theme options theme_advanced_buttons1 : "cut,copy,paste,pastetext,pasteword,selectall,|,undo,redo,|,cleanup,removeformat,|", theme_advanced_buttons2 : "bold,italic,underline,|,bullist,numlist,|,forecolor,backcolor,|", theme_advanced_buttons3 : "", theme_advanced_buttons4 : "", theme_advanced_toolbar_location : "top", theme_advanced_toolbar_align : "left", theme_advanced_statusbar_location : "none", theme_advanced_resizing : false, //plugins plugins : "inlinepopups,paste", dialog_type : "modal", paste_auto_cleanup_on_paste : true, setup: function(ed){ ed.onInit.add(function(ed){ //check for addEventListener -- primarily supported by firefox only var edDoc = ed.getDoc(); if ("addEventListener" in edDoc){ edDoc.addEventListener("focus", function(){ tinymce_focus(); }, false); edDoc.addEventListener("blur", function(){ tinymce_blur(); }, false); } }); } }); }); Any ideas as to why it's not working in IE8?

  • My SqlComand on SSIS - DataFlow OLE DB Command seems not works

    - by Angel Escobedo
    Hello Im using OLE DB Source for get rows from a dBase IV file and it works, then I split the data and perform a group by with aggregate component. So I obtain a row with two columns with "null" value : CompanyID | CompanyName | SubTotal | Tax | TotalRevenue Null Null 145487 27642.53 173129.53 this success because all rows have been grouped with out taking care about the firsts columns and just Summing the valuable columns, so I need to change that null for default values as CompanyID = "100000000" and CompanyName = "Others". I try use SqlCommand on a OLE DB Command Component : SELECT "10000000" AS RUCCLI , "Otros - Varios" AS RAZCLI FROM RGVCAFAC <property id="1505" name="SqlCommand" dataType="System.String" state="default" isArray="false" description="The SQL command to be executed." typeConverter="" UITypeEditor="Microsoft.DataTransformationServices.Controls.ModalMultilineStringEditor, Microsoft.DataTransformationServices.Controls, Version=10.0.0.0, Culture=neutral, PublicKeyToken=89845dcd8080cc91" containsID="false" expressionType="Notify">SELECT "10000000" AS RUCCLI , "Otros - Varios" AS RAZCLI FROM RGVCAFAC</property> but nothings happens, why? and finally the task finish when the data is inserted on a SQL Server Table. Im using the same connection manager on extracting data and transform. (View Code) <DTS:Property DTS:Name="ConnectionString">Data Source=C:\CONTA\Resocen\Agosto\;Provider=Microsoft.Jet.OLEDB.4.0;Persist Security Info=False;Extended Properties=dBASE IV;</DTS:Property></DTS:ConnectionManager></DTS:ObjectData></DTS:ConnectionManager> all work is on memory, Im not using cache manager connections

  • Nested table height in TCPDF

    - by Kuroki Kaze
    Is it possible to make nested table fit height of its parent cell in TCPDF? My code: <?php require_once('tcpdf/config/lang/eng.php'); require_once('tcpdf/tcpdf.php'); $pdf = new TCPDF(PDF_PAGE_ORIENTATION, PDF_UNIT, PDF_PAGE_FORMAT, true, 'UTF-8', false); $pdf->setPrintHeader(false); $pdf->setPrintFooter(false); $pdf->SetFont('times', 'BI', 8); $pdf->AddPage(); $pdf->writeHTML('<table> <tr><td bgcolor="gray"> Angoisse et vif espoir, sans humeur factieuse.<br/> Plus allait se vidant le fatal sablier,<br/> Plus ma torture était âpre et délicieuse;<br/> Tout mon coeur s’arrachait au monde familier</td> <td bgcolor="lightgray">Second</td> <td bgcolor="gray">Third</td> <td> <table style="height: 100%"> <tr bgcolor="blue" style="height: 30%"><td bgcolor="yellow" style="height: 30%">Ichi</td></tr> <tr bgcolor="white" style="height: 30%"><td bgcolor="cyan" style="height: 30%">Ni</td></tr> <tr bgcolor="blue" style="height: 30%"><td bgcolor="yellow" style="height: 30%">San</td></tr> </table> </td></tr> </table>'); $pdf->Output('example_002.pdf', 'I'); ?> I want table in last cell to fill it entirely.

  • Prevent Jquery Accordion tab from expanding

    - by Edwin
    I'm trying to use JQuery UI Accordion as a menu, but I can't figure out how to prevent some tabs from expanding. My JS: $("#sidebar").accordion({ collapsible: true, changestart: function(event, ui) { switch ($(ui.newHeader).attr("id")) { case "sidebar_grades": return false; break; } } }); the HTML: <div id="sidebar"> <h3 id="sidebar_home"> <a href="/blah">Home</a> </h3> <div> <a href="/child">Settings</a> </div> <h3 id="sidebar_grades"> <a href="/grades">Grades</a> </h3> <div></div> <h3 id="sidebar_calendar"> <a href="/calendar">Calendar</a> </h3> <div></div> </div> In the above example, since #sidebar_grades doesn't have any child, it should not be expandable, but user can click on the link. I tried using "changestart" event and return false when #sidebar_grades is clicked, but it doesn't work. I also tried attaching onClick event to #sidebar_grades to return false, but that didn't work either. Any idea how to do this? Thank you!

  • while loop ignore the event listener

    - by Tamer
    so when i run this code to try to change the background the GUI crashes and gets stuck in a infinite while loop ignoring the event listeners. here is the code: `private Panel getPanel1() { if (panel1 == null) { panel1 = new Panel(); panel1.setLayout(new GridBagLayout()); while(frame.isVisible()){ panel1.addMouseListener(new java.awt.event.MouseAdapter() { public void mouseClicked(java.awt.event.MouseEvent e) { frame.setVisible(false); } }); int r = (int) (Math.random()*255); int g = (int) (Math.random()*255); int b = (int) (Math.random()*255); Color c = new Color(r, g, b); panel1.setBackground(c); try { Thread.sleep(4000); } catch (InterruptedException e1) { e1.printStackTrace(); } panel1.addMouseListener(new java.awt.event.MouseAdapter() { public void mouseClicked(java.awt.event.MouseEvent e) { /*panel1.setVisible(false); frame.setVisible(false);*/ System.exit(0); } }); } } return panel1; }` instead of exiting the loop of terminating the program or event changing the background it just displays the panel and does nothing else and i have to force it to quit. what should i do?

  • Opening href in jQuery Dialog

    - by Phil
    Okay, so I've got the following code to create a dialog of a div within a page: $('#modal').dialog({ autoOpen: false, width: 600, height: 450, modal: true, resizable: false, draggable: false, title: 'Enter Data', close: function() { $("#modal .entry_date").datepicker('hide'); } }); $('.modal').click(function() { $('#modal').dialog('open'); }); All working fine. But what I want is to also be able to open a link in a dialog window, kinda like... <a href="/path/to/file.html" class="modal">Open Me!!</a> I've done this before by hardcoding the path: $('#modal').load('/path/to/file.html').dialog('open'); but we can't hardcode the path in the javascript (as there will be multiple coming from the database) and I'm struggling to understand how to get this to work. I'm also pretty sure that the answer is really obvious, and I'm merely setting myself up to be humbled by the clever folk here at StackOverflow, but I've scratched my head for long enough this afternoon, so my ego has been put away, and hopefully someone can point me in the right direction... Thanks Phil

  • Rails - difference between config.cache_store and config.action_controller.cache_store?

    - by gsmendoza
    If I set this in my environment config.action_controller.cache_store = :mem_cache_store ActionController::Base.cache_store will use a memcached store but Rails.cache will use a memory store instead: $ ./script/console >> ActionController::Base.cache_store => #<ActiveSupport::Cache::MemCacheStore:0xb6eb4bbc @data=<MemCache: 1 servers, ns: nil, ro: false>> >> Rails.cache => #<ActiveSupport::Cache::MemoryStore:0xb78b5e54 @data={}> In my app, I use Rails.cache.fetch(key){ object } to cache objects inside my helpers. All this time, I assumed that Rails.cache uses the memcached store so I'm surprised that it uses memory store. If I change the cache_store setting in my environment to config.cache_store = :mem_cache_store both ActionController::Base.cache_store and Rails.cache will now use the same memory store, which is what I expect: $ ./script/console >> ActionController::Base.cache_store => #<ActiveSupport::Cache::MemCacheStore:0xb7b8e928 @data=<MemCache: 1 servers, ns: nil, ro: false>, @middleware=#<Class:0xb7b73d44>, @thread_local_key=:active_support_cache_mem_cache_store_local_cache> >> Rails.cache => #<ActiveSupport::Cache::MemCacheStore:0xb7b8e928 @data=<MemCache: 1 servers, ns: nil, ro: false>, @middleware=#<Class:0xb7b73d44>, @thread_local_key=:active_support_cache_mem_cache_store_local_cache> However, when I run the app, I get a "marshal dump" error in the line where I call Rails.cache.fetch(key){ object } no marshal_dump is defined for class Proc Extracted source (around line #1): 1: Rails.cache.fetch(fragment_cache_key(...), :expires_in => 15.minutes) { ... } vendor/gems/memcache-client-1.8.1/lib/memcache.rb:359:in 'dump' vendor/gems/memcache-client-1.8.1/lib/memcache.rb:359:in 'set_without_newrelic_trace' What gives? Is Rails.cache meant to be a memory store? Should I call controller.cache_store.fetch in the places where I call Rails.cache.fetch?

  • AndEngine Physics Editor loading level

    - by Khawar Raza
    I have created a .pes file using PhysicsEditor and imported as xml and have added to my project. When I parsed it and created bodies, it is showing strange behavior. The mapping of bodies that I created in PhysicsEditor is totally different what I see in my application means the shapes I draw in PhysicsEditor are rendering differently in my app. Here is my xml and code to parse and add bodies to scene. PhysicsEditor XML file: <?xml version="1.0" encoding="UTF-8"?> <!-- created with http://www.physicseditor.de --> <bodydef version="1.0"> <bodies numBodies="1"> <body name="car_path" dynamic="false" numFixtures="1"> <fixture density="2" friction="1" restitution="0" filter_categoryBits="1" filter_groupIndex="0" filter_maskBits="65535" isSensor="false" type="POLYGON" numPolygons="20" > <polygon numVertexes="6"> <vertex x="277.0000" y="152.0000" /> <vertex x="356.0000" y="172.0000" /> <vertex x="413.0000" y="194.0000" /> <vertex x="476.0000" y="223.0000" /> <vertex x="173.0000" y="232.0000" /> <vertex x="174.0000" y="148.0000" /> </polygon> <polygon numVertexes="4"> <vertex x="1556.0000" y="221.0000" /> <vertex x="1142.0000" y="94.0000" /> <vertex x="1255.0000" y="-15.0000" /> <vertex x="1554.0000" y="-14.0000" /> </polygon> <polygon numVertexes="3"> <vertex x="-192.0000" y="177.0000" /> <vertex x="-888.0000" y="139.0000" /> <vertex x="-549.0000" y="-125.0000" /> </polygon> <polygon numVertexes="6"> <vertex x="1762.0000" y="24.0000" /> <vertex x="1862.0000" y="27.0000" /> <vertex x="1927.0000" y="68.0000" /> <vertex x="2078.0000" y="222.0000" /> <vertex x="1643.0000" y="212.0000" /> <vertex x="1642.0000" y="38.0000" /> </polygon> <polygon numVertexes="3"> <vertex x="-1150.0000" y="146.0000" /> <vertex x="-1776.0000" y="140.0000" /> <vertex x="-1476.0000" y="-25.0000" /> </polygon> <polygon numVertexes="4"> <vertex x="-2799.0000" y="103.0000" /> <vertex x="-2684.0000" y="223.0000" /> <vertex x="-3112.0000" y="256.0000" /> <vertex x="-3108.0000" y="98.0000" /> </polygon> <polygon numVertexes="3"> <vertex x="3112.0000" y="255.0000" /> <vertex x="2422.0000" y="222.0000" /> <vertex x="3120.0000" y="-71.0000" /> </polygon> <polygon numVertexes="4"> <vertex x="1142.0000" y="94.0000" /> <vertex x="1556.0000" y="221.0000" /> <vertex x="709.0000" y="226.0000" /> <vertex x="911.0000" y="93.0000" /> </polygon> <polygon numVertexes="6"> <vertex x="-2111.0000" y="89.0000" /> <vertex x="-2067.0000" y="94.0000" /> <vertex x="-2002.0000" y="139.0000" /> <vertex x="-2344.0000" y="223.0000" /> <vertex x="-2196.0000" y="112.0000" /> <vertex x="-2153.0000" y="91.0000" /> </polygon> <polygon numVertexes="4"> <vertex x="105.0000" y="233.0000" /> <vertex x="-94.0000" y="178.0000" /> <vertex x="69.0000" y="106.0000" /> <vertex x="91.0000" y="104.0000" /> </polygon> <polygon numVertexes="3"> <vertex x="-2002.0000" y="139.0000" /> <vertex x="-2067.0000" y="94.0000" /> <vertex x="-2032.0000" y="110.0000" /> </polygon> <polygon numVertexes="4"> <vertex x="-1150.0000" y="146.0000" /> <vertex x="105.0000" y="233.0000" /> <vertex x="-2344.0000" y="223.0000" /> <vertex x="-2002.0000" y="139.0000" /> </polygon> <polygon numVertexes="3"> <vertex x="413.0000" y="194.0000" /> <vertex x="356.0000" y="172.0000" /> <vertex x="376.0000" y="176.0000" /> </polygon> <polygon numVertexes="3"> <vertex x="105.0000" y="233.0000" /> <vertex x="-192.0000" y="177.0000" /> <vertex x="-94.0000" y="178.0000" /> </polygon> <polygon numVertexes="4"> <vertex x="105.0000" y="233.0000" /> <vertex x="-1150.0000" y="146.0000" /> <vertex x="-888.0000" y="139.0000" /> <vertex x="-192.0000" y="177.0000" /> </polygon> <polygon numVertexes="3"> <vertex x="3112.0000" y="255.0000" /> <vertex x="-3112.0000" y="256.0000" /> <vertex x="-2684.0000" y="223.0000" /> </polygon> <polygon numVertexes="3"> <vertex x="3112.0000" y="255.0000" /> <vertex x="1556.0000" y="221.0000" /> <vertex x="1643.0000" y="212.0000" /> </polygon> <polygon numVertexes="3"> <vertex x="709.0000" y="226.0000" /> <vertex x="173.0000" y="232.0000" /> <vertex x="476.0000" y="223.0000" /> </polygon> <polygon numVertexes="3"> <vertex x="3112.0000" y="255.0000" /> <vertex x="2078.0000" y="222.0000" /> <vertex x="2422.0000" y="222.0000" /> </polygon> <polygon numVertexes="3"> <vertex x="3112.0000" y="255.0000" /> <vertex x="105.0000" y="233.0000" /> <vertex x="173.0000" y="232.0000" /> </polygon> </fixture> </body> </bodies> <metadata> <format>1</format> <ptm_ratio></ptm_ratio> </metadata> </bodydef> And here is my code: private void loadLevel() { // TODO Auto-generated method stub AssetManager assetManager = getAssets();

  • Check for valid IMEI

    - by Tim
    Hi, does somebody knows how to check for a valid IMEI? I have found a function to check on this page: http://www.dotnetfunda.com/articles/article597-imeivalidator-in-vbnet-.aspx But it returns false for valid IMEI's (f.e. 352972024585360). I can validate them online on this page: http://www.numberingplans.com/?page=analysis&sub=imeinr What is the correct way(in VB.Net) to check if a given IMEI is valid? Regards, Tim PS: This function from above page must be incorrect in some way: Public Shared Function isImeiValid(ByVal IMEI As String) As Boolean Dim cnt As Integer = 0 Dim nw As String = String.Empty Try For Each c As Char In IMEI cnt += 1 If cnt Mod 2 <> 0 Then nw += c Else Dim d As Integer = Integer.Parse(c) * 2 ' Every Second Digit has to be Doubled nw += d.ToString() ' Genegrated a new number with doubled digits End If Next Dim tot As Integer = 0 For Each ch As Char In nw.Remove(nw.Length - 1, 1) tot += Integer.Parse(ch) ' Adding all digits together Next Dim chDigit As Integer = 10 - (tot Mod 10) ' Finding the Check Digit my Finding the Remainder of the sum and subtracting it from 10 If chDigit = Integer.Parse(IMEI(IMEI.Length - 1)) Then ' Checking the Check Digit with the last digit of the Given IMEI code Return True Else Return False End If Catch ex As Exception Return False End Try End Function

  • Jquery Form ajaxSubmit not submitting

    - by Gazler
    Hi, I am using the JQuery Form extension to submit a form with AJAX. I have the following code: var options = { beforeSubmit: showRequest, // pre-submit callback success: showResponse, // post-submit callback // other available options: //url: url // override for form's 'action' attribute //type: 'post', // 'get' or 'post', override for form's 'method' attribute //dataType: null // 'xml', 'script', or 'json' (expected server response type) clearForm: true, // clear all form fields after successful submit //resetForm: true // reset the form after successful submit // $.ajax options can be used here too, for example: timeout: 3000 }; $('#composeForm').submit(function() { // inside event callbacks 'this' is the DOM element so we first // wrap it in a jQuery object and then invoke ajaxSubmit $(this).find(':disabled').removeAttr('disabled'); $(this).ajaxSubmit(options); // !!! Important !!! // always return false to prevent standard browser submit and page navigation return false; }); The problem is that the form doesn't appear to be submitting, or atleast the success function is not being called. If I remove the return false, then the submission works, but the page navigates away. Is there a problem in my code that could be causing this? Cheers, Gazler.

  • What was your most useful/inspiring computer science course?

    - by MPelletier
    I'm currently taking one course per semester, remotely, in a short 5 year program. My aim is to get better at my trade (programming and analysis, not surprisingly). However, I find that I'm not inspired by my choice of classes for next semester. Maybe I'm being too judgmental. I'd like to know what positive experience was gained from a course in particular. Have ou had a course that turned out to be an idea catalyst?

  • File Format DOS/Unix/MAC code sample

    - by mac
    I have written the following method to detemine whether file in question is formatted with DOS/ MAC, or UNIX line endings. I see at least 1 obvious issue: 1. i am hoping that i will get the EOL on the first run, say within first 1000 bytes. This may or may not happen. I ask you to review this and suggest improvements which will lead to hardening the code and making it more generic. THANK YOU. new FileFormat().discover(fileName, 0, 1000); and then public void discover(String fileName, int offset, int depth) throws IOException { BufferedInputStream in = new BufferedInputStream(new FileInputStream(fileName)); FileReader a = new FileReader(new File(fileName)); byte[] bytes = new byte[(int) depth]; in.read(bytes, offset, depth); a.close(); in.close(); int thisByte; int nextByte; boolean isDos = false; boolean isUnix = false; boolean isMac = false; for (int i = 0; i < (bytes.length - 1); i++) { thisByte = bytes[i]; nextByte = bytes[i + 1]; if (thisByte == 10 && nextByte != 13) { isDos = true; break; } else if (thisByte == 13) { isUnix = true; break; } else if (thisByte == 10) { isMac = true; break; } } if (!(isDos || isMac || isUnix)) { discover(fileName, offset + depth, depth + 1000); } else { // do something clever } }

  • Marshalling C# com items when using recursion

  • Silverlight P2P App (In Browser) - Will we get RTMFP?

    - by Paul
    Ok so from all my research I'm fairly positive P2P is not possible in Silverlight 4 (in browser). Flash can do P2P using Stratus/RTMFP which I believe uses UDP hole punching and a Stratus server to help initialize the connection. Is there any plans for Microsoft to add some kind of p2p rendezvous service in the future? Can we get a definitive yes/no on whether or not p2p is possible in SL4.

  • Showing/hiding a JPopupMenu from a JButton; FocusListener not working?

    - by M. Joanis
    Hi everyone, I needed a JButton with an attached dropdown style menu. So I took a JPopupMenu and attached it to the JButton in the way you can see in the code below. What it needs to do is this: show the popup when clicked hide it if clicked a second time hide it if an item is selected in the popup hide it if the user clicks somewhere else in the screen These 4 things work, but because of the boolean flag I'm using, if the user clicks somewhere else or selects an item, I have to click twice on the button before it shows up again. That's why I tried to add a FocusListener (which is absolutely not responding) to fix that and set the flag false in these cases. Here are the listeners: (It's in a class extending JButton, so the second listener is on the JButton.) // Show popup on left click. menu.addFocusListener(new FocusListener() { @Override public void focusLost(FocusEvent e) { System.out.println("LOST FOCUS"); isShowingPopup = false; } @Override public void focusGained(FocusEvent e) { System.out.println("GAINED FOCUS"); } }); addActionListener(new ActionListener() { @Override public void actionPerformed(ActionEvent e) { System.out.println("isShowingPopup: " + isShowingPopup); if (isShowingPopup) { isShowingPopup = false; } else { Component c = (Component) e.getSource(); menu.show(c, -1, c.getHeight()); isShowingPopup = true; } } }); I've been fighting with this for way too long now. If someone can give me a clue about what's wrong with this, it would be great! Thanks!

  • What is a Bias Value of Floating Point Numbers?

    - by mudge
    In learning how floating point numbers are represented in computers I have come across the term "bias value" that I do not quite understand. The bias value in floating point numbers has to do with the negative and positiveness of the exponent part of a floating point number. The bias value of a floating point number is 127 which means that 127 is always added to the exponent part of a floating point number. How does doing this help determine if the exponent is negative or positive or not?

  • .NET Reference "Copy Local" True / Fasle Being Set Based on Contents of General Assembly

    - by D-Sect
    Hello All. First question for me here. We had a very interesting problem with a Win Forms project. It's been resolved. We know what happened, but we want to understand why it happened. This may help other people out in the future who have a similar problem. The WinForms project failed on 2 of our client's PCs. The error was an obscure kernel.dll error. The project ran fine on 3 other PCs. We found that a .DLL (log4net.dll - a very popular open-source logging library) was missing from our release folder. It was previously in our release folder. Why was it missing in this latest release? It was missing because I must have installed a program on my Dev box that used log4net.dll and it was added to the general assembly. When I checked the SLN's references for log4net.dll, they were changed to "copy local=FALSE". They must have changed automagicially because log4net.dll was present in my GAC. Here's where my question starts: Why did my reference for log4net.dll get changed from COPY LOCAL = TRUE to COPY LOCAL = FALSE? I suspect it's because it was added to my GAC by another program. How can we prevent this from happening again? As it stands now, if I install a piece of software that uses a common library and it adds it to my GAC, then my SLNs that REF that DLL will change from Copy Local TRUE to FALSE. Thank you so much. I hope this helps people out who have a piece of software that runs in some places, but not in others, when it used to run fine in ALL places.

  • Highcharts Area graph, use 2 fill colors above / below X axis

    - by Kris Chant
    In Highcharts, I'd like to fill an Area graph with 2 colors, positive values get one color, negative values get another color. I've been able to do this with a linearGradient, but this must be adjusted based upon the size of the container. Is there a more general way of doing this, e.g. setting values 0 color 1, values < 0 color 2? See my JSFiddle for more information and an example: http://jsfiddle.net/GNvur/2/

  • Haars Cascade for Actionscript development

    - by Andre
    Hi guys, I have an object that I want to be able to recognize in AS3. There's a port of OpenCV for AS3 already, that works with Haars cascades, so now I need to create a cascade of my object. From what I've read, I'll have to create an XML of several images (positive and negative), but I can't find a program that'll do that for Mac OS X. Is there anything I can use that'll generate that XML on Mac OS X? Cheers, Andre

Any ideas? Edit 19/02 - Added the entire code. I know it's real messy and not neat, but I want to get it functioning first. Spend last two days trying to fix.
