  • Why would my Silverlight 4 Out-of-Browser application just display white?

    - by Edward Tanguay
    My Silverlight application works fine when running in a browser. But when I install it as an out-of-browser application, the Window frame comes up with an appropriate icon and title, but the content of the window is just white. It is in the start menu but when I close it and open again, it is still blank. I reproduced this on Windows 7 and Windows XP. What could be causing my silverlight application to show only white when running out-of-browser? Here are the settings I used:

  • Converting a list into a select with jquery

    - by Davemof
    I'm trying to convert the following list into a select list so it can be submitted via a form - the element within the lists will become the value of each option: <ul class="selected connected-list ui-sortable" style="height: 279px;"> <li class="ui-helper-hidden-accessible" style=""></li> <li title="Owner Name 1 - " class="ui-state-default ui-element ui-draggable" style="display: block; position: relative; top: 0px; left: 0px;"><span class="ui-icon-arrowthick-2-n-s ui-icon"></span>Owner Name 1 - <em class="thenumber">4.4796E+11</em><a class="action" href="#"><span class="ui-corner-all ui-icon ui-icon-minus"></span></a></li> <li title="David Moffat - " class="ui-state-default ui-element" style="display: block; position: relative; top: 0px; left: 0px;"><span class="ui-icon ui-icon-arrowthick-2-n-s"></span>David Moffat - <em class="thenumber">07730423005</em><a class="action" href="#"><span class="ui-corner-all ui-icon ui-icon-minus"></span></a></li> </ul> This should convert to the following format: <select style="display:none" class="selectoption" name="p_num[]" multiple="multiple"> <option value="">4.4796E+11</option> <option value="">07730423007</option> </select> I have tried the following jquery code, but after many hours I'm pulling my hair out: $('a.sendform').click(function(){ $('ul.selected').each(function() { var $select = $('<select />'); $(this).find('li').each(function() { var $option = $('<option />'); $option.attr('value', $(this).('em')).html($(this).html()); $select.append($option); }); $(this).replaceWith($select); }); }); Any help might save my remaining hair. Many thanks David

  • Jquery - Loading a page with .load and selector doesn't execute script?

    - by PirateKitten
    I'm trying to load one page into another using the .load() method. This loaded page contains a script that I want to execute when it has finished loading. I've put together a barebones example to demonstrate: Index.html: <html> <head> <title>Jquery Test</title> <script type="text/javascript" src="script/jquery-1.3.2.min.js"></script> <script type="text/javascript"> $(document).ready(function() { $('#nav a').click(function() { $('#contentHolder').load('content.html #toLoad', '', function() {}); return false; }); }); </script> </head> <body> <div id="nav"> <a href="content.html">Click me!</a> </div> <hr /> <div id="contentHolder"> Content loaded will go here </div> </body> </html> Content.html: <div id="toLoad"> This content is from content.html <div id="contentDiv"> This should fade away. </div> <script type="text/javascript"> $('#contentDiv').fadeOut('slow', function() {} ); </script> </div> When the link is clicked, the content should load and the second paragraph should fade away. However it doesn't execute. If I stick a simple alert("") in the script of content.html it doesn't execute either. However, if I do away with the #toLoad selector in the .load() call, it works fine. I am not sure why this is, as the block is clearly in the scope of the #toLoad div. I don't want to avoid using the selector, as in reality the content.html will be a full HTML page, and I'll only want a select part out of it. Any ideas? If the script from content.html was in the .load() callback, it works fine, however I obviously don't want that logic contained within index.html. I could possibly have the callback use .getScript() to load "content.html.js" afterwards and have the logic in there, that seems to work? I'd prefer to keep the script in content.html, if possible, so that it executes fine when loaded normally too. In fact, I might do this anyway, but I would like to know why the above doesn't work.

  • Providing updating suggestions list with javascript, php and ajax

    - by user1104854
    I'm trying to modify this example on making a live updating list to integrate it with my API. So, instead of using GET on the page with the form, I'd like to send it to that page via a function call. So, here's my form // message.php //function to display the hint sent from gethint.php function message_hint($hint){ echo $hint; } //displays the form for sending messages function send_message_form($to_user,$title,$message){ include 'gethint.php'; ?> <table> <form name = "send_message" method="post"> <td>Send A Message</td> <tr><td>To:</td><td><input type = "text" size="50" name="to_user" id = "to_user" value ="<? echo $to_user; ?>" onkeyup="showHint(this.value)"></td></tr> <tr><td>Title:</td><td><input type = "text" size="50" name="message_title"></td></tr> <tr><td>Message:</td><td><textarea rows="4" cols="50" name="message_details"></textarea></td></tr> <tr><td><input type="submit" name="submit_message"></td></tr> </table> </form> <? } Here's the head of message.php <head> <script> function showHint(str){ var to_user = document.getElementById("to_user").value //to_user is the id of the textbox if (str.length==0){ to_user.innerHTML=""; return; } if (window.XMLHttpRequest){// code for IE7+, Firefox, Chrome, Opera, Safari xmlhttp=new XMLHttpRequest(); }else{// code for IE6, IE5 xmlhttp=new ActiveXObject("Microsoft.XMLHTTP"); } xmlhttp.onreadystatechange=function(){ if (xmlhttp.readyState==4 && xmlhttp.status==200){ alert(to_user) //properly displays the name via alert box to_user.innerHTML=xmlhttp.responseText; } } xmlhttp.open("GET","gethint.php?q="+to_user,true); xmlhttp.send(); } </script> </head> The page gethint.php is exactly the same, aside from this at the bottom. //echo $response //this was the original output $message = new messages; $message->message_hint($response);

    - by goh
    Hi lads, After obtaining the urls for various blogspots, tumblr and wordpress pages, I faced some problems processing the html pages. The thing is, i wish to distinguish between the content,title and date for each blog post. I might be able to get the date through regex, but there are so many custom scripts people are using now that the html classes and structure is so different. Does anyone has a solution that may help?

  • WP7 PanoramaItem with Icon/Button next to Header

    - by Ramon Bosch
    Windows Phone 7's People hub has an "all" panorama item with "search" and a "new" buttons right next to the header/title. I can't seem to accomplish this with PanoramaItem in Visual Studio using the standard Panorama control. I don't know enough Silverlight/WPF either to be able to position something manually and control transitions/movement correctly. How can I set a button (or any object, for that matter) to go alongside the header of a wp7 PanoramaItem? Thanks!
