  • MD5CryptoServiceProvider ComputeHash Issues between VS 2003 and VS 2008

    - by owensoroke
    I have a database application that generates a MD5 hash and compares the hash value to a value in our DB (SQL 2K). The original application was written in Visual Studio 2003 and a deployed version has been working for years. Recently, some new machines on the .NET framework 3.5 have been having unrelated issues with our runtime. This has forced us to port our code path from Visual Studio 2003 to Visual Studio 2008. Since that time the hash produced by the code is different than the values in the database. The original call to the function posted in code is: RemoveInvalidPasswordCharactersFromHashedPassword(Text_Scrub(GenerateMD5Hash(strPSW))) I am looking for expert guidance as to whether or not the MD5 methods have changed since VS 2K3 (causing this point of failure), or where other possible problems may be originating from. I realize this may not be the best method to hash, but utimately any changes to the MD5 code would force us to change some 300 values in our DB table and would cost us a lot of time. In addition, I am trying to avoid having to redeploy all of the functioning versions of this application. I am more than happy to post other code including the RemoveInvalidPasswordCharactersFromHashedPassword function, or our Text_Scrub if it is necessary to recieve appropriate feedback. Thank you in advance for your input. Public Function GenerateMD5Hash(ByVal strInput As String) As String Dim md5Provider As MD5 ' generate bytes for the input string Dim inputData() As Byte = ASCIIEncoding.ASCII.GetBytes(strInput) ' compute MD5 hash md5Provider = New MD5CryptoServiceProvider Dim hashResult() As Byte = md5Provider.ComputeHash(inputData) Return ASCIIEncoding.ASCII.GetString(hashResult) End Function

  • problem linking vba modules in MS Access 2007

    - by Ted
    I am upgrading a database system from Access 2000 db to Access 2007, which communicates with several chemistry measuring devices(pH meter, scale, etc) via an RS 232 serial port. The first db consists of several modules containing vba code that enables the communications with the ports, as well as supports the code behind the forms in the second db. The user, or lab tech, navigates through the forms in the second db to interact with the lab devices, and also to generate the reports which display the info. from the devices. The reports are also part of the second db. The code works in Access 2000, but once I convert it to 2007, the code in the second db cannot find the function calls in the first db that dictate the progression from screen to screen. I have tried importing the modules into the second db, and I have tried linking them, but it still doesn't work. The error message is #438: "Object doesn't support this property or method." Any suggestions would be greatly appreciated. Here is the code for the first function that is not being called correctly: Description: ' This routine is used to return to the calling form and close the active form. ' ' Input: ' strFormCalled --- the active form ' strCallingForm --- the form that called the active form ' blnUnhideOrOpen --- whether to open or just unhide form Public Sub basReturnToCallingForm(ByVal strFormCalled As String, ByVal _ strCallingForm As Variant, Optional blnUnhideOrOpen As Boolean = True) On Error GoTo err_basReturnToCaliingForm If Not basIsBlankString(strCallingForm) And blnUnhideOrOpen Then DoCmd.OpenForm strCallingForm, acNormal Else Call basUnHideForm(strCallingForm) End If Call basCloseForm(strFormCalled) exit_basReturnToCaliingForm: Exit Sub err_basReturnToCaliingForm: Err.Raise Err.Number, "basReturnToCaliingForm", Err.Description End Sub I will post the second function shortly, but I have to go to a meeting... The second funtion that isn't 'working' is a cmdStartClick that is supposed to be called when a user initializes a pump. However, within that function, it's also sticking on a line that is supposed to progress to the next form in the db. The other thing is that the code works in Access 2002, but not in Access 2007...

  • How to store and locate multiple interface types within a Delphi TInterfaceList

    - by Brian Frost
    Hi, I'm storing small interfaces from a range of objects into a single TInterfaceList 'store' with the intention of offering list of specific interface types to the end user, so each interface will expose a 'GetName' function but all other methods are unique to that interface type. For example here are two interfaces: IBase = interface //---------------------------------------- function GetName : string; //---------------------------------------- end; IMeasureTemperature = interface(IBase) //------------------------------------ function MeasureTemperature : double; //---------------------------------------- end; IMeasureHumidity = interface(IBase) //---------------------------------------- function MeasureHumidity: double; //---------------------------------------- end; I put several of these interfaces into a single TInterfaceList and then I'd like to scan the list for a specific interface type (e.g. 'IMeasureTemperature') building another list of pointers to the objects exporting those interfaces. I wish to make no assumptions about the locations of those objects, some may export more than one type of interface. I know I could do this with a class hierarchy using something like: If FList[I] is TMeasureTemperature then .. but I'd like to do something simliar with an interface type, Is this possible?

  • Tying in .addClass() with other functions?

    - by Anders H
    Assuming an accordion dropdown with the standard form of: <ul> <li> <a href="#">Main Element</a> <ul> <li> <a href="#">Dropdown Element</a> </li> </ul> </li> </ul> I'm using jQuery to expand when the parent element link is clicked: var $j = jQuery.noConflict(); function initMenus() { $j('ul.menu ul').hide(); $j.each($j('ul.menu'), function(){ $j('#' + this.id + '.expandfirst ul:first').show(); }); $j('ul.menu li a').click( function() { var checkElement = $j(this).next(); var parent = this.parentNode.parentNode.id; if($j('#' + parent).hasClass('noaccordion')) { $j(this).next().slideToggle('normal'); return false; } if((checkElement.is('ul')) && (checkElement.is(':visible'))) { if($j('#' + parent).hasClass('collapsible')) { $j('#' + parent + ' ul:visible').slideUp('normal'); } return false; } if((checkElement.is('ul')) && (!checkElement.is(':visible'))) { $j('#' + parent + ' ul:visible').slideUp('normal'); checkElement.slideDown('normal'); return false; } } ); } $j(document).ready(function() {initMenus();}); To add a class to the Main Element when clicked (aka the class is enabled anytime the dropdown is expanded) I'm trying to use .toggleClass(className) without luck, most likely to my positioning. Where can I add this element to get the desired effect?

I just need a hint because I'm not sure where to turn to... can I achieve it with mouseover?

    Hi All, Im having a bit of trouble getting my JSON to be recognised by my web page. I have validated JSON that im getting returned from server, so i know that is correct, however my javascript function is not doing anything with it. My succes function is as follows: success: function(data) { $('input[name=customer_name]').val(data.name); $('textarea[name=customer_address]').text(data.address); $('input[name=customer_email]').val(data.email); $('input[name=customer_tel]').val(data.tel); $('input[name=user_id]').val(item.id); } Yet the fields are not being repopulated with the data that is returned, if it helps, a sample of my JSON data: { "name": "Terry O'Toole", "address": "Terrys House\nTerry Street\nTerrysville\nTerrytown\nTT1 6TT", "email": "[email protected]", "tel": "05110000000" } Any help would be appreciated. [EDIT] Expanded ajax call: $.ajax({ url: "<?php echo site_url('user/users/ajax'); ?>", type: 'POST', data: {"userid": item.id}, success: function(data) { $('input[name=customer_name]').val(data.name); $('textarea[name=customer_address]').text(data.address); $('input[name=customer_email]').val(data.email); $('input[name=customer_tel]').val(data.tel); $('input[name=user_id]').val(item.id); } }) });

  • IE AJAX/Jquery issue - redirecting to new page instead of loading it into a div

    - by phx-zs
    I have a page like this: <form class="ajax" method="post" action="add_item.php"> [text input] [submit button] </form> [list any items the user has in a div here called #items] When the user clicks the submit button, a function like this is called: $("form.ajax").live('submit', function(event) { params = $(this).serialize(); $.post($(this).attr("action"), params, function(data){ json = $.parseJSON(data); // do stuff based on the json results if(json.success.action == 'replace'){ $(json.success.container).html(json.success.message); } else{ $(json.success.container).prepend(json.success.message); $(json.success.container).find(".item:first").slideDown(); } }); event.returnValue = false; return false; }); This is supposed to load add_item.php into the #items div, and it works fine in FF, Chrome, Safari, just not IE. In IE (tested 7 and 8) when I click Submit it redirects the page to add_item.php rather than loading it into the #items div. I tried adding event.preventDefault(); to the end of the function but that didn't work. Any ideas?

  • Preloading Image Bug in IE6-8

    - by Kevin C.
    Page in question: http://phwsinc.com/our-work/one-rincon-hill.asp In IE6-8, when you click the left-most thumbnail in the gallery, the image never loads. If you click the thumbnail a second time, then it will load. I'm using jQuery, and here's my code that's powering the gallery: $(document).ready(function() { // PROJECT PHOTO GALLERY var thumbs = $('.thumbs li a'); var photoWrapper = $('div.photoWrapper'); if (thumbs.length) { thumbs.click( function(){ photoWrapper.addClass('loading'); var img_src = $(this).attr('href'); // The two lines below are what cause the bug in IE. They make the gallery run much faster in other browsers, though. var new_img = new Image(); new_img.src = img_src; var photo = $('#photo'); photo.fadeOut('slow', function() { photo.attr('src', img_src); photo.load(function() { photoWrapper.removeClass('loading'); photo.fadeIn('slow'); }); }); return false; }); } }); A coworker told me that he's always had problems with the js Image() object, and advised me to just append an <img /> element inside of a div set to display:none;, but that's a little messy for my tastes--I liked using the Image() object, it kept things nice and clean, no unnecessary added HTML markup. Any help would be appreciated. It still works without the image preloading, so if all else fails I'll just wrap the preloading in an if !($.browser.msie){ } and call it a day.

  • Object inside of array -- works in one scope but not in another?

    - by Earlz
    Ok I've been learning some of the more advanced aspects of Javascript and now trying to use this I'm stuck. Here is my code: function Data(){} function init(state){ var item; item=new Data(); item.fieldrid=17; item.description='foo'; state.push(item); }; function findInState(state,fieldrid) { for (var item in state) { alert(item.fieldrid); //prints undefined if (item.fieldrid == fieldrid) { return item; } } return null; } var s=[]; init(s); alert(s[0].fieldrid); //prints 17 (expected) alert(findInState(s,17).fieldrid); //exception here. function returns null. A running example is here at jsbin Why does this not work? I would expect the alert in findInState to yield 17 but instead it yields undefined. What am I doing wrong?

  • Jquery.Validate plugin + realPerson plugin

    - by Dave Watts
    I can't figure out how to make it so the form wont fire unless the realPerson captcha is "valid". I can see that when the user types in the correct/valid letters and clicks submit it adds a class of "valid" to the input. So Ive been trying to figure out how to get the jquery.validate plugin to only fire when the class "valid" is present. <script type="text/javascript"> $(document).ready(function(){ $('#defaultReal').realperson(); $('#contact_form2').validate({ submitHandler: function(form) { var str = $("form").serialize(); $.ajax({ type: "POST", url: "contactpage.php", data: str, success: function(){ $('#contact_form2').html("<div id='message'></div>"); $('#message').html("<h2>Contact Form Submitted!</h2>") .append("<p>We will be in touch soon.</p>") .hide() .fadeIn(1500, function() { $('#message').append("<img id='checkmark' src='images/check.png' />"); }); }}); return false; } }); Thank you in advanced! -Dave

  • Freeing ImageData when deleting a Canvas

    - by user578770
    I'm writing a XUL application using HTML Canvas to display Bitmap images. I'm generating ImageDatas and imporingt them in a canvas using the putImageData function : for(var pageIndex=0;pageIndex<100;pageIndex++){ this.img = imageDatas[pageIndex]; /* Create the Canvas element */ var imgCanvasTmp = document.createElementNS("http://www.w3.org/1999/xhtml",'html:canvas'); imgCanvasTmp.setAttribute('width', this.img.width); imgCanvasTmp.setAttribute('height', this.img.height); /* Import the image into the Canvas */ imgCanvasTmp.getContext('2d').putImageData(this.img, 0, 0); /* Use the Canvas into another part of the program (Commented out for testing) */ // this.displayCanvas(imgCanvasTmp,pageIndex); } The images are well imported but there seems to be a memory leak due to the putImageData function. When exiting the "for" loop, I would expect the memory allocated for the Canvas to be freed but, by executing the code without executing putImageData, I noticed that my program at the end use 100Mb less (my images are quite big). I came to the conclusion that the putImageData function prevent the garbage collector to free the allocated memory. Do you have any idea how I could force the garbage collector to free the memory? Is there any way to empty the Canvas? I already tried to delete the canvas using the delete operator or to use the clearRect function but it did nothing. I also tried to reuse the same canvas to display the image at each iteration but the amount of memory used did not changed, as if the image where imported without deleting the existing ones...

  • How to keep track of call statistics? C++

    - by tf.rz
    I'm working on a project that delivers statistics to the user. I created a class called Dog, And it has several functions. Speak, woof, run, fetch, etc. I want to have a function that spits out how many times each function has been called. I'm also interested in the constructor calls and destructor calls as well. I have a header file which defines all the functions, then a separate .cc file that implements them. My question is, is there a way to keep track of how many times each function is called? I have a function called print that will fetch the "statistics" and then output them to standard output. I was considering using static integers as part of the class itself, declaring several integers to keep track of those things. I know the compiler will create a copy of the integer and initialize it to a minimum value, and then I'll increment the integers in the .cc functions. I also thought about having static integers as a global variable in the .cc. Which way is easier? Or is there a better way to do this? Any help is greatly appreciated!

  • firefox does not load large size images

    - by Pradeep
    I am stuck with a kind of bug in FF, wherein it’s unable to load images of big size (I have 8 MB size of image) from the server. The loading of image is all fine on IE. I am still looking out for ways to get rid of this problem. I changed server(IIS) settings to allow bigger file sizes. Also, I used “load” event on image using JQuery and tried all sort of options listed here http://api.jquery.com/load-event/, but nothing worked so far. If anyone of you has come across any such similar problem, and a way to resolve it, it would be nice to hear from you Please note: high resolution images are part of the requirement. Code : <style> img { background-color: #FFFFFF; background-image: url(http://eremurus.hyd:8080/QMS/plugin/imagepanner/loader.gif); background-repeat: no-repeat; background-position: center center; } </style> <script src="../plugin/jquery-ui-1.8.7.custom/js/jquery-1.4.4.min.js" type="text/javascript"></script> <script> jQuery(document).ready(function($){ ///var _url = "http://eremurus.hyd:8080/QMS/plugin/imagepanner/floorPlan.jpg"; // set up the node / element _im =$("#main"); //_im.bind("load",function(){ $(this).fadeIn(); }); // set the src attribute now, after insertion to the DOM //_im.attr('src',_url); $("#main").one("load",function(){ alert('loaded'); }) .each(function(){ if(this.complete){ $(this).trigger("load"); } }); }); </script> </head> <body> <div id="target"><img id='main' src="http://eremurus.hyd:8080/QMS/plugin/imagepanner/floorPlan.jpg"> </img></div> </body> </html>

  • Adding property:value pairs from GooglemapsAPI to an existing json/javascript object

    - by Rockinelle
    I am trying to create a script that finds the closest store/location to a customer using googlemapsAPI. So I've got a json object which is a collection of store objects. Using Jquery's .each to iterate through that object, I am grabbing the driving time from the customer to each store. If it finds the directions, It copies the duration of the drive which is an object with the time in seconds and a human readable value. That appears to work, however when I try to sort through all of those store objects with the drivetime added, I cannot read the object copied from google. If I console.log the whole object, 'closest_store', It shows the values I'm looking for. When I try to read the values directly via closest_store.driveTime, Firebug is outputting undefined in the console. What am I missing here? $.getJSON('<?php echo Url::base() ?>oldservices/get_locations', {}, function(data){ $.each(data, function(index, value) { var end = data[index].address; var request = { origin: start, destination: end, travelMode: google.maps.DirectionsTravelMode.DRIVING }; directionsService.route(request, function(response, status) { //console.log(response); if (status == google.maps.DirectionsStatus.OK) { value.driveTime = response.trips[0].routes[0].duration.value; //console.log(response.trips[0].routes[0].duration.value); }; }); }); var closest_store; $.each(data, function(index, current_store) { if (index == 0) { closest_store = current_store; } else if (current_store.driveTime.value < closest_store.driveTime.value) { closest_store = value }; console.log(current_store.driveTime); } ) });

  • Timing issues with playback of the HTML5 Audio API

    - by pat
    I'm using the following code to try to play a sound clip with the HTML5 Audio API: HTMLAudioElement.prototype.playClip = function(startTime, stopTime) { this.stopTime = stopTime; this.currentTime = startTime; this.play(); $(this).bind('timeupdate', function(){ if (this.ended || this.currentTime >= stopTime) { this.pause(); $(this).unbind('timeupdate'); } }); } I utilize this new playClip method as follows. First I have a link with some data attributes: <a href=# data-stop=1.051 data-start=0.000>And then I was thinking,</a> And finally this bit of jQuery which runs on $(document).ready to hook up a click on the link with the playback: $('a').click(function(ev){ $('a').click(function(ev){ var start = $(this).data('start'), stop = $(this).data('stop'), audio = $('audio').get(0), $audio = $(audio); ev.preventDefault(); audio.playClip(start,stop); }) This approach seems to work, but there's a frustrating bug: sometimes, the playback of a given clip plays beyond the correct data-stop time. I suspect it could have something to do with the timing of the timeupdate event, but I'm no JS guru and I don't know how to begin debugging the problem. Here are a few clues I've gathered: The same behavior appears to come up in both FF and Chrome. The playback of a given clip actually seems to vary a bit -- if I play the same clip a couple times in a row, it may over-play a different amount of time on each playing. Is the problem here the inherent accuracy of the Audio API? My app needs milliseconds. Is there a problem with the way I'm using jQuery to bind and unbind the timeupdate event? I tried using the jQuery-less approach with addEventListener but I couldn't get it to work. Thanks in advance, I would really love to know what's going wrong.

  • Disable specific dates in jquery

    - by rvdb86
    I am using the jquery date picker found here: http://www.kelvinluck.com/assets/jquery/datePicker/v2/demo/datePickerStartEnd.html that allows the user to pick a start and end date. However I want to be able to disable specific dates. I tried to implement the code found here: stackoverflow.com/questions/501943/can-the-jquery-ui-datepicker-be-made-to-disable-saturdays-and-sundays-and-holida that discusses disabling national holidays. Here is my complete code: $(function() { $('.date-pick').datePicker({ beforeShowDay: nationalDays}) // $(".selector").datepicker({ beforeShowDay: nationalDays}) var natDays = [ [1, 26, 'au'], [2, 6, 'nz'], [3, 17, 'ie'], [4, 27, 'za'], [5, 25, 'ar'], [6, 6, 'se'], [7, 4, 'us'], [8, 17, 'id'], [9, 7, 'br'], [10, 1, 'cn'], [11, 22, 'lb'], [12, 12, 'ke'] ]; function nationalDays(date) { for (i = 0; i < natDays.length; i++) { if (date.getMonth() == natDays[i][0] - 1 && date.getDate() == natDays[i][1]) { return [false, natDays[i][2] + '_day']; } } return [true, '']; } $('#start-date').bind( 'dpClosed', function(e, selectedDates) { var d = selectedDates[0]; if (d) { d = new Date(d); $('#end-date').dpSetStartDate(d.addDays(1).asString()); } } ); $('#end-date').bind( 'dpClosed', function(e, selectedDates) { var d = selectedDates[0]; if (d) { d = new Date(d); $('#start-date').dpSetEndDate(d.addDays(-1).asString()); } } ); }); But this does not seem to work. I would really appreciate any assistance with solving this!

  • IE8 ignores jQuery UI 'dialog' minHeight and height settings

    - by Kev
    I'm using jQuery 1.4.4 with jQueryUI 1.8.7 to display a modal dialog box. I'm having a problem where IE8 renders a scrollbar and appears to ignore the minHeight and height options in all the many different combinations I've tried them in. In Chrome 8 and Firefox 3.6 my dialogue looks like: In IE 8 it looks like: The markup and script looks like: <a id="create" href="#">Create New Thing</a> <div id="dlg-create-thing" title="Create new thing?"> <form name="create-thing-form" id="dlg-create-thing-form"> <p style="text-align:left"> <span>Name: <input id="thingName" name="thingName" maxlength="12" size="30" /></span> <br /><br /> <b>Thing options:</b><br /><br /> <input type="radio" id="option1" name="theoptions" value="0" checked="checked" />Use this option<br /> <input type="radio" id="option1AndMem" name="theoptions" value="1" />Use this other option </p> </form> </div> <script type="text/javascript"> $(function () { $("#dlg-create-thing").dialog({ autoOpen: false, resizable: false, width: 500, modal: true, minHeight: 280, buttons: { "Create": function () { /* do stuff */ }, "Cancel": function () { /* do other stuff */} } }); $("body").delegate("a[id='create']", "click", function () { $("#dlg-create-thing").dialog('open'); return false; } ); }); </script> How can I fix this (preferably in a nice browser agnostic way, but I'd settle for anything)?

  • Using TXMLDocument to serialize form settings to XML and database.

    I have an interface: type IXMLSerializable = interface function SaveToXML : DOMString; function SaveToXMLDocument : IXMLDocument; procedure LoadFromXML(AXML : DOMString); end; It is used to serialize some settings of forms or frames to xml. Simple implementation: SaveToXMLDocument: function TSomething.SaveToXMLDocument: IXMLDocument; begin Result := TXMLDocument.Create(nil); with Result do begin Active := True; with AddChild(Self.Name) do begin AddChild(edSomeTextBox.Name).Attributes['Text'] := edSomeTextBox.Text; end; end; Result := XMLDoc; end; LoadFromXML: procedure TSomething.LoadFromXML(AXML: DOMString); var XMLDoc : IXMLDocument; I : Integer; begin XMLDoc := TXMLDocument.Create(nil); with XMLDoc do begin LoadFromXML(AXML); Active := True; with ChildNodes[0] do begin for I := 0 to ChildNodes.Count-1 do begin If ChildNodes[I].NodeName = 'edSomeTextBox' then edSomeTextBox.Text := ChildNodes[I].Attributes['Text']; end; end; end; end; SaveToXML: function TSomething.SaveToXML: DOMString; begin SaveToXMLDocument.SaveToXML(Result); end; DOMString result of SaveToXML is saved to database to blob field. I had some encoding issues with other implementations and this one works fine (right now). Do you see any dangers in this code? Can I have issues with different settings on various machines and systems?

  • C++ RPC library suggestions

    - by Oxsnarder
    I'm looking for suggestions regarding RPC libraries implemented in C++, for C++ developers. Some requirements constraints: Should work on both linux/unix and win32 systems Be able to execute free function and class methods Hopefully written in modern C++ not 90's/java-esque C++ Be able to function over networks and hetrogenous architectures Not too slow or inefficient Hopefully provide interfaces for TR1 style std::function's et al. My example usage is to invoke the free function foo on a remote machine. ---snip--- // foo translation unit int foo(int i, int j) { return i + j; } ---snip--- ---snip--- // client side main int main() { //register foo on client and server //setup necassary connections and states int result; if (RPCmechanism.invoke("foo",4,9,result)) std::cout << "foo(4,9) = " result << std::endl; else std::cout << "failed to invoke foo(4,9)!" << std::endl; return 0; } ---snip--- Something that can achieve the above or similar would be great.

  • cakephp isAuthorized() not being called

    - by Jack B Nimble
    I am trying to use the isAuthorized() method to do a check for an admin flag, but the function never seems to be called. Even when I set the function to always return false, it allows any user. It just seems like it isn't being called. Do I need to do something more than setting $this-Auth-authorize = 'controller' ? from /app/app_controller.php class AppController extends Controller { var $components = array('Auth'); function beforeFilter() { $this->Auth->loginAction = array('controller' => 'users', 'action' => 'login'); $this->Auth->loginRedirect = array('controller' => 'pages', 'display' => 'home'); $this->Auth->logoutRedirect = '/'; $this->Auth->authorize = 'controller'; $this->Auth->userScope = array('User.active' => 1); } function isAuthorized() { if (strpos($this->action, "admin_") != false) { if ($this->Auth->user('isAdmin') == '0') { return false; } } return true; } }

  • jQuery - Compatibility Problem with Internet Explorer 7 and Opera

    - by Marius
    Hello there, I have this counter which counts + 1 every time somebody shares content from the site. When it happens, the social icon that was clicked will bounce. It works in Firefox,Chrome, IE8, and Opera, however the bouncing animation is wrong in opera. $.fn.countExternal = function(animSpeed, num) { // for each counter this.each(function(){ // select all the digit containers var span = $(this).children(); // count the num of digit containers var len = $(span).length; // get the current count u = $(span).text(); // copy variable and add increment(s) v = num + ''; // foreach digit container... for (i=v.length - 1; i >= 0; i--) { // ...check which digits are not affected by the increment(s) if (v.charAt(i) == u.charAt(i)) { break; } } // slice from the total number of digit containers the digits containers which needs updating. slce = len - (v.length - (i + 1)) var updates = $(span).slice(slce); // loop through each digit container and fade out ... $(updates).fadeTo(animSpeed, 0,function(){ $(updates).each(function(index){ f = i + 1 + index; // ...then pick the right digit and update the digit... $(this).text(v.charAt(f)); // ...before fading back in. Cycle complete. $(this).fadeTo(animSpeed, 1); }); }); }); }; }) (jQuery); Demo (NSFW) is here (look underneath the social sharing icons). Any idea how I can solve the IE, and possibly the Opera compatibility problem? Thank you for your time.

    I'm trying to close a socket after a connection times out after 1000ms. I am able to set a timeout that gets triggered after a 1000ms but I can't seem to destroy the socket... any ideas? var connection = http.createClient(80, 'localhost'); var request = connection.request('GET', '/somefile.xml', {'host':'localhost'}); var start = new Date().getTime(); request.socket.setTimeout(1000); request.socket.addListener("timeout", function() { request.socket.destroy(); sys.puts("socket timeout connection closed"); }); request.addListener("response", function(response) { var responseBody = []; response.setEncoding("utf8"); response.addListener("data", function(chunk) { sys.puts(chunk); responseBody.push(chunk); }); response.addListener("end", function() { }); }); request.end(); returns socket timeout connection closed node.js:29 if (!x) throw new Error(msg || "assertion error"); ^ Error: assertion error at node.js:29:17 at Timer.callback (net:152:20) at node.js:204:9
