  • jQuery ajaxForm "h is undefined" problem

    - by Simon
    I have a form that is brought up in a ajaxed modal which I am using for updating user details. When the modal loads I call a js function: teamCreate: function() { $j("#step1,form#createEditTeam").show(); $j("#step2").hide(); var options = { type: "get", dataType: 'json', beforeSubmit: before, // pre-submit callback success: success // post-submit callback }; $j("form#createEditTeam").ajaxForm(options); function before(formData, jqForm, options){ var valid = $j("form#createEditTeam").valid(); if (valid === true) { $j(".blockMsg").block({ message: $j('#panelLoader') }); return true; // submit the form } else { $j("form#createEditTeam").validate(); return false; // prevent form from submitting } }; function success(data){ if (data.status == "success") { $j(".blockMsg").unblock(); } else { // } }; function error(xhr, ajaxOptions, thrownError){ alert("Error code: " + xhr.statusText); }; } This works just fine when I first submit the form, regardless how many times the modal is opened and closed. However, if I submit the form and then open the modal again and try to submit the form again I get a js error: h is undefined

  • C# HTML tags inside GridView

    - by Geo Ego
    I have a SharePoint web part that I wrote in C# which is used to display SQL Server data based on user selections. I pull the data with a DataReader, fill a DataSet with it, and set that DataSet as the DataSource in a GridView and add that control to my page. The only problem I'm facing is that line breaks in the data fields are not being rendered at all. I'm simply getting a block of text that ignores the breaks that are present in the database when it's rendered to HTML. I tried a regex: Regex rgx = new Regex("\n"); string inputStr = Convert.ToString(dr[x]); string outputStr = rgx.Replace(inputStr, "<br />"); newRow[ds3.Tables["Bobst Specs 3"].Columns[x]] = outputStr; While that does detect and replace the newlines, I merely get the text "" with no line breaks. I also tried changing my SQL query to something along the lines of: SELECT REPLACE (fldCustomerName, '. ', '.' + @NewLineChar) This apparently renders more newlines. I can see that they are present, because if I also insert the regex they are affected, but do not create line breaks. I'm not sure how to replace these, and what with, to get the lines to actually break.

  • is this uibutton autoreleased ?

    - by dubbeat
    HI This is just a question to check my sanity really. I'm hunting memory leaks that show up in instruments but not the static analyzer. In one spot the analyzer is pointing to this block of code UIButton *randomButton = [UIButton buttonWithType:UIButtonTypeRoundedRect ]; randomButton.frame = CGRectMake(205, 145, 90, 22); // size and position of button [randomButton setTitle:@"Random" forState:UIControlStateNormal]; randomButton.backgroundColor = [UIColor clearColor]; randomButton.adjustsImageWhenHighlighted = YES; [randomButton addTarget:self action:@selector(getrandom:) forControlEvents:UIControlEventTouchUpInside]; [self.view addSubview:randomButton]; For some reason I thought the above code would auto release the button because I'm not calling init or alloc? If I add [randombutton release] at the bottom of the code my button fails to show. Could somebody describe to me the correct way to release a button from memory that is created in the above way? Or would I be better off making the button a class variable and sticking the release in the dealloc method?

  • How to force the build to be out of date, when a text file is modified?

    - by demoncodemonkey
    The Scenario My project has a post-build phase set up to run a batch file, which reads a text file "version.txt". The batch file uses the information in version.txt to inject the DLL with a version block using this tool. The version.txt is included in my project to make it easy to modify. It looks a bit like this: @set #Description="TankFace Utility Library" @set #FileVersion="0.1.2.0" @set #Comments="" Basically the batch file renames this file to version.bat, calls it, then renames it back to version.txt afterwards. The Problem When I modify version.txt (e.g. to increment the file version), and then press F7, the build is not seen as out-of-date, so the post-build step is not executed, so the DLL's version doesn't get updated. I really want to include the .txt file as an input to the build, but without anything actually trying to use it. If I #include the .txt file from a CPP file in the project, the compiler fails because it obviously doesn't understand what "@set" means. If I add /* ... */ comments around the @set commands, then the batch file has some syntax errors but eventually succeeds. But this is a poor solution I think. So... how would you do it?

  • How can I automatically release resources RAII-style in Perl?

    - by Philip Potter
    Say I have a resource (e.g. a filehandle or network socket) which has to be freed: open my $fh, "<", "filename" or die "Couldn't open filename: $!"; process($fh); close $fh or die "Couldn't close filename: $!"; Suppose that process might die. Then the code block exits early, and $fh doesn't get closed. I could explicitly check for errors: open my $fh, "<", "filename" or die "Couldn't open filename: $!"; eval {process($fh)}; my $saved_error = $@; close $fh or die "Couldn't close filename: $!"; die $saved_error if $saved_error; but this kind of code is notoriously difficult to get right, and only gets more complicated when you add more resources. In C++ I would use RAII to create an object which owns the resource, and whose destructor would free it. That way, I don't have to remember to free the resource, and resource cleanup happens correctly as soon as the RAII object goes out of scope - even if an exception is thrown. Unfortunately in Perl a DESTROY method is unsuitable for this purpose as there are no guarantees for when it will be called. Is there a Perlish way to ensure resources are automatically freed like this even in the presence of exceptions? Or is explicit error checking the only option?

  • verilog / systemverilog -- What is the behavior of blocking statements across two always blocks?

    - by miles.sherman
    I am wondering about the behavior of the below code. There are two always blocks, one is combinational to calculate the next_state signal, the other is sequential which will perform some logic and determine whether or not to shutdown the system. It does this by setting the shutdown_now signal high and then calling state <= next_state. My question is if the conditions become true that the shutdown_now signal is set (during clock cycle n) in a blocking manner before the state <= next_state line, will the state during clock cycle n+1 be SHUTDOWN or RUNNING? In other words, does the shutdown_now = 1'b1 line block across both state machines since the state signal is dependent on it through the next_state determination? enum {IDLE, RUNNING, SHUTDOWN} state, next_state; logic shutdown_now; // State machine (combinational) always_comb begin case (state) IDLE: next_state <= RUNNING; RUNNING: next_state <= shutdown ? SHUTDOWN : RUNNING; SHUTDOWN: next_state <= SHUTDOWN; default: next_state <= SHUTDOWN; endcase end // Sequential Behavior always_ff @ (posedge clk) begin // Some code here if (/*some condition) begin shutdown_now = 1'b0; end else begin shutdown_now = 1'b1; end state <= next_state; end

  • How to instantiate spring bean without being referenced from aop:aspect

    - by XDeveloper
    Using Spring and Java; I have a pointcut which works OK. Now I want to remove the pointcut and AOP from the spring and just trigger the event with an event from inside the java code but I want "myAdvice" bean still called via Spring and its properties set. I want to get ridoff all advice things even in java code, no more advice or any trace of AOP, I already have a nice event system working. I just want to instantiate my bean via Spring. When I remove the second code block (one starting with "aop:config") then I noticed the bean "myAdvice" is not called and instantiated anymore. How can i stil call it set its properties without referencing it from the "aop:aspect" ? in my application context ; <bean id="myAdvice" class="com.myclass"> <property name="name1" ref="ref1" /> <property name="name2" ref="ref2" /> </bean> <aop:config proxy-target-class="true"> <aop:aspect id="myAspect" ref="myAdvice"> <aop:pointcut id="myPointcut" expression="execution(* com.myexcmethod" /> <aop:around pointcut-ref="myPointcut" method="invoke" /> </aop:aspect> </aop:config>

  • Why do Firefox and Opera ignore max-width inside of display: table-cell?

    - by brad
    The following code displays correctly in Chrome or IE (the image is 200px wide). In Firefox and Opera the max-width style is ignored completely. Why does this happen and is there a good work around? Also, which way is most standards compliant? Note One possible work around for this particular situation is to set max-width to 200px. However, this is a rather contrived example. I'm looking for a strategy for a variable width container. <!doctype html> <html> <head> <style> div { display: table-cell; padding: 15px; width: 200px; } div img { max-width: 100%; } </style> </head> <body> <div> <img src="http://farm4.static.flickr.com/3352/4644534211_b9c887b979.jpg" /> <p> Lorem ipsum dolor sit amet, consectetur adipiscing elit. Donec facilisis ante, facilisis posuere ligula feugiat ut. Fusce hendrerit vehicula congue. at ligula dolor. Lorem ipsum dolor sit amet, consectetur adipiscing elit. leo metus, aliquam eget convallis eget, molestie at massa. </p> </div> </body> </html> [Update] As stated by mVChr below, the w3.org spec states that max-width does not apply to inline elements. I've tried using div img { max-width: 100%; display: block; }, but it does not seem to correct the issue.

  • How do I add a comment to an image using jQuery

    - by marcamillion
    So I am trying to replicate Facebook's picture tagging functionality, and I have the functionality that onClick, a box is created and there is a comment box. Now the issue is that I want to be able to (without doing any back-end processing) take the input from the input field and add it in some form to the underlying image area that they have selected. I would also like to add a small image to that area, that shows that a comment is there. How do I do that? See the code below for what I have for the comment box: <script type="text/javascript"> $(function() { var tag_box = $("<div>").appendTo("body").css({ "width": "40px", "height":"40px", "border":"4px solid #000000", "position":"absolute", "display":"none", "padding":"15px" }); var comment_box = $("<form action='#'><input id='comment' type='text' name='comment' placeholder='Add comment'></form>").appendTo(tag_box).css({"position":"absolute"}); $("#image-wrapper").live('click', function(e){ tag_box.css({ "left": e.pageX - 40, "top": e.pageY - 40, "display": "block" }) .after(comment_box.css({ "left": e.pageX - 65, "top": e.pageY + 40 })); }); }); </script> Now...whenever the user presses enter, the info in the comment box is appended to the URL like so: .html?comment=comment value# Thanks

  • Flex 3 Close UrlLoader throws exception

    - by gmoniey
    I am trying to simulate a 'HEAD' method using UrlLoader; essentially, I just want to check for the presence of a file without downloading the entire thing. I figured I would just use HttpStatusEvent, but the following code throws an exception (one that I can't wrap in a try/catch block) when you run in debug mode. <mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute" initialize="init()"> <mx:Script> <![CDATA[ private static const BIG_FILE:String = "http://www.archive.org/download/gspmovvideotestIMG0021mov/IMG_0021.mov"; private var _loader:URLLoader; private function init():void { _loader = new URLLoader(); _loader.addEventListener(HTTPStatusEvent.HTTP_STATUS, statusHandler); _loader.addEventListener(IOErrorEvent.IO_ERROR, errorHandler); _loader.addEventListener(SecurityErrorEvent.SECURITY_ERROR, errorHandler); _loader.load(new URLRequest(BIG_FILE)); } public function unload():void { try { _loader.close(); _loader.removeEventListener(HTTPStatusEvent.HTTP_STATUS, statusHandler); _loader.removeEventListener(IOErrorEvent.IO_ERROR, errorHandler); _loader.removeEventListener(SecurityErrorEvent.SECURITY_ERROR, errorHandler); } catch(error:Error) { status.text = error.message; } } private function errorHandler(event:Event):void { status.text = "error"; unload(); } private function statusHandler(event:HTTPStatusEvent):void { if(event.status.toString().match(/^2/)) { status.text = "success"; unload(); } else { errorHandler(event); } } ]]> </mx:Script> <mx:Label id="status" /> I tried using ProgressEvents instead, but it seems that some 404 pages return content, so the status event will correctly identify if the page exists. Anyone have any ideas?

  • iPhone UI layout debugging

    - by Cruinh
    I have this chronic issue with iPhone UI development where views sometimes seem to appear on the screen in a location different than what is reported by their frame property. Here is what I am doing to try to debug the issue: UIView *currentView = self.view; while (currentView!=nil) { NSLog(@"frame: %f,%f,%f,%f", currentView.frame.origin.x, currentView.frame.origin.y, currentView.frame.size.width, currentView.frame.size.height); currentView = currentView.superview; } I expect this should show me the coordinates and size of each element up the hierarchy from the given view to the app's root UIWindow element, with the coordinates for each element relative to its parent. However, that does not seem to be the case. In my current situation, I have a UI I'm trying to debug where every other time I rotate the device, the whole UI shifts up or down 20 pixels, yet the code block above reports exactly the same numbers every time. I tried calling the above code after as much as a second delay, but that the numbers still come out the same each time. Does anyone know a better way to inspect the screen coordinates of UI elements? If I can detect when one is wrong, I can compensate for the problem when it appears.

  • Why is this SocketException not caught by a generic catch routine?

    - by Tarnschaf
    Our company provides a network component (DLL) for a GUI application. It uses a Timer that checks for disconnections. If it wants to reconnect, it calls: internal void timClock_TimerCallback(object state) { lock (someLock) { // ... try { DoConnect(); } catch (Exception e) { // Log e.Message omitted // Raise event with e as parameter ErrorEvent(this, new ErrorEventArgs(e)); DoDisconnect(); } // ... } } So the problem is, inside of the DoConnect() routine a SocketException is thrown (and not caught). I would assume, that the catch (Exception e) should catch ALL exceptions but somehow the SocketException was not caught and shows up to the GUI application. protected void DoConnect() { // client = new TcpClient(); client.NoDelay = true; // In the following call the SocketException is thrown client.Connect(endPoint.Address.ToString(), endPoint.Port); // ... (login stuff) } The doc confirmed that SocketException extends Exception. The stacktrace that showed up is: TcpClient.Connect() -> DoConnect() -> timClock_TimerCallback So the exception is not thrown outside the try/catch block. Any ideas why it doesn't work?

  • Is there a tag in XHTML that you can put anywhere in the body - even inside TABLE elements?

    - by Iain Fraser
    I would like to be able to place an empty tag anywhere in my document as a marker that can be addressed by jQuery. However, it is important that the XHTML still validates. To give you a bit of background as to what I'm doing: I've compared the current and previous versions of a particular document and I'm placing markers in the html where the differences are. I'm then intending to use jQuery to highlight the parent block-level elements when highlightchanges=true is in the URL's query string. At the moment I'm using <span> tags but it occurred to me that this sort of thing wouldn't validate: <table> <tr> <td>Old row</td> </tr> <span class="diff"></span><tr> <td>Just added</td> </tr> </table> So is there a tag I can use anywhere? Meta tag maybe? Thanks for your help! Iain

  • CSS doesn't apply to dynamically created elements in IE 7?

    - by Austin Hyde
    In the project I am working on, I dynamically generate (with javascript) filters that look like this: <div class="filter"> <a ... class="filter_delete_link">Delete</a> <div class="filter_field"> ... </div> <div class="filter_compare"> ... </div> <div class="filter_constraint"> ... </div> <div class="filter_logic"> ... </div> </div> And I have CSS that applies to each filter (for example): .filter a.filter_delete_link{ display:block; height:16px; background: url('../images/remove_16.gif') no-repeat; padding-left:20px; } However, it seems in IE 7 (and probably 6 for that matter), these styles don't get applied to the new filters. Everything works perfectly in Firefox/Chrome/IE8. Using the IE8 developer tools, set to IE7 mode, the browser can see the new elements, and can see the CSS, but just isn't applying the CSS. Is there a way to force IE to reload styles, or perhaps is there a better way to fix this?

  • jQuery Accordion + OL + IE6 bug

    - by DA
    Sample page: http://jsbin.com/ohuze/2 This is a simple jQuery UI Accordion. Each accordion panel has an UL (an OL works the same) with this markup: <ol> <li><a href="">Lorep ipsum dolor lorem ipsum dolor lorem ipsum dolor</a>?</li> <li><a href="">Lorep ipsum dolor lorem ipsum dolor lorem ipsum dolor</a>?</li> </ol> In IE6, you'll see that the <a> tag appears to be getting rendered as a block element, so the question mark ends up being pushed outside and not at the end of the line of text. In addition, the bullet and/or list item number is now bottom-aligned with the text rather than top-aligned. I've narrowed it down to the javascript that executes to make the accordion. It's not an issue with jQuery's CSS as disabling that, alone, doesn't resolve the issue. Anyone know what might be going on in IE6 to cause this rendering issue? UPDATE: Apparently, this is also an IE7 issue.

  • How to TDD Asynchronous Events?

    - by Padu Merloti
    The fundamental question is how do I create a unit test that needs to call a method, wait for an event to happen on the tested class and then call another method (the one that we actually want to test)? Here's the scenario if you have time to read further: I'm developing an application that has to control a piece of hardware. In order to avoid dependency from hardware availability, when I create my object I specify that we are running in test mode. When that happens, the class that is being tested creates the appropriate driver hierarchy (in this case a thin mock layer of hardware drivers). Imagine that the class in question is an Elevator and I want to test the method that gives me the floor number that the elevator is. Here is how my fictitious test looks like right now: [TestMethod] public void TestGetCurrentFloor() { var elevator = new Elevator(Elevator.Environment.Offline); elevator.ElevatorArrivedOnFloor += TestElevatorArrived; elevator.GoToFloor(5); //Here's where I'm getting lost... I could block //until TestElevatorArrived gives me a signal, but //I'm not sure it's the best way int floor = elevator.GetCurrentFloor(); Assert.AreEqual(floor, 5); } Edit: Thanks for all the answers. This is how I ended up implementing it: [TestMethod] public void TestGetCurrentFloor() { var elevator = new Elevator(Elevator.Environment.Offline); elevator.ElevatorArrivedOnFloor += (s, e) => { Monitor.Pulse(this); }; lock (this) { elevator.GoToFloor(5); if (!Monitor.Wait(this, Timeout)) Assert.Fail("Elevator did not reach destination in time"); int floor = elevator.GetCurrentFloor(); Assert.AreEqual(floor, 5); } }

  • strange behavior in python

    - by fsm
    The tags might not be accurate since I am not sure where the problem is. I have a module where I am trying to read some data from a socket, and write the results into a file (append) It looks something like this, (only relevant parts included) if __name__ == "__main__": <some init code> for line in file: t = Thread(target=foo, args=(line,)) t.start() while nThreads > 0: time.sleep(1) Here are the other modules, def foo(text): global countLock, nThreads countLock.acquire() nThreads += 1 countLock.release() """connect to socket, send data, read response""" writeResults(text, result) countLock.acquire() nThreads -= 1 countLock.release() def writeResults(text, result): """acquire file lock""" """append to file""" """release file lock""" Now here's the problem. Initially, I had a typo in the function 'foo', where I was passing the variable 'line' to writeResults instead of 'text'. 'line' is not defined in the function foo, it's defined in the main block, so I should have seen an error, but instead, it worked fine, except that the data was appended to the file multiple times, instead of being written just once, which is the required behavior, which I got when I fixed the typo. My question is, 1) Why didn't I get an error? 2) Why was the writeResults function being called multiple times?

  • Preserving SCRIPT tags (and more) in CKEditor

    - by Jonathan Sampson
    Update: I'm thinking the solution to this problem is in CKEDITOR.config.protectedSource(), but my regular-expression experience is proving to be too juvenile to handle this issue. How would I go about exempting all tags that contain the 'preserved' class from being touched by CKEditor? Is it possible to create a block of code within the CKEditor that will not be touched by the editor itself, and will be maintained in its intended-state until explicitly changed by the user? I've been attempting to input javascript variables (bound in script tags) and a flash movie following, but CKEditor continues to rewrite my pasted code/markup, and in doing so breaking my code. I'm working with the following setup: <script type="text/javascript"> var editor = CKEDITOR.replace("content", { height : "500px", width : "680px", resize_maxWidth : "680px", resize_minWidth : "680px", toolbar : [ ['Source','-','Save','Preview'], ['Cut','Copy','Paste','PasteText','PasteFromWord','-','Print', 'SpellChecker', 'Scayt'], ['Undo','Redo','-','Find','Replace','-','SelectAll','RemoveFormat'], ['Bold','Italic','Underline','Strike','-','Subscript','Superscript'], ['NumberedList','BulletedList','-','Outdent','Indent','Blockquote'], ['JustifyLeft','JustifyCenter','JustifyRight','JustifyBlock'], ['Link','Unlink','Anchor'], ['Image','Table','HorizontalRule','SpecialChar'] ] }); CKFinder.SetupCKEditor( editor, "<?php print url::base(); ?>assets/ckfinder" ); </script> UPDATE: I suppose the most ideal solution would be to preserve the contents of any tag that contains class="preserve" enabling much more than the limited exclusives.

  • Ruby Fileutils.cp_r Permission Denied when :preserve => true

    - by slawley
    Hello, I am trying to implement a poor-man's backup/mirroring script and am having some trouble. I am on Windows-XP, using Ruby's FileUtils module to recursively copy files. So long as I don't set the :preserve flag to true, everything works fine. Works: FileUtils.cp_r('Source_dir', 'Dest_dir', :verbose => true) Doesn't work: FileUtils.cp_r('Source_dir', 'Dest_dir', :verbose => true, :preserve => true) I have full permissions on the Dest_dir as it's on the desktop of my local machine and I just created it. I can copy and delete files and folders, but apparently changing, or maintaining the file attributes with :preserve isn't working. I haven't had a chance to try this on a Mac or linux box, but from reading around online the :preserve flag is a normal stumbling block to come up against in a Windows environment. In a similar line of questioning, what is the default behavior for FileUtils.cp_r when it encounters an existing file at the destination directory? Simply overwrite and replace everything in Destination with whatever is in Source, or can I skip a file with conflicts and just log it for resolution later? (If this should be a separate question, just let me know and I'll make it one.) Thanks, Spencer

  • Appropriate wx.Sizer(s) for the job?

    - by MetaHyperBolic
    I have a space in which I would like certain elements (represented here by A, B, D, and G) to each be in its own "corner" of the design. The corners ought to line up as if each of the four elements was repelling the other; a rectangle. This is to be contained within an unresizable panel. I will have several similar panels and want to keep the location of the elements as identical as possible. (I needed something a little more complex than a wx.Wizard, but with the same general idea.) AAAAAAAAAA BB CCCCCCCCCCCCCCCCCC CCCCCCCCCCCCCCCCCC CCCCCCCCCCCCCCCC CCCCCCCCCCCCCC CCCCCCCCCCCCCCCCCC CCCCCCCCCCCCCCCC CCCCCCCCCCCCCCCCCC DDD EEE FFF GGG A represents a text in a large font. B represents a numeric progress meter (e.g. "1 of 7") in a small font. C represents a large block of text. D, E, F, and G are buttons. The G button is separated from others for functionality. I have attempted nested wx.BoxSizers (horizontal boxes inside of one vertical box) without luck. My first problem with wx.BoxSizer is that the .SetMinSize on my last row has not been honored. The second problem is that I have no idea how to make the G button "take up space" without growing comically large, or how I can jam it up against the right edge and bottom edge. I have tried to use a wx.GridBagSizer, but ran into entirely different issues. After plowing through the various online tutorials and wxPython in Action, I'm a little frustrated. The relevant forums appear to see activity once every two weeks. "Playing around with it" has gotten me nowhere; I feel as if I am trying to smooth out a hump in ill-laid carpet.

  • How to get DIVs into this code via JQuery

    - by ludz
    Heya everyone I been struggling along with this piece of code for the longest time, its driving me insane. I am trying many different things and looking at past posts here but nothing seems to be helping. Basicly i have a jquery pagination code in place and i want to add animated transitions between pages. With some assistance i got that working correctly however this causes the page to jump around as the new items fade in and out. To fix this i need a DIV wrapped around each selection of results. I have been trying to use .wrap .html .wrapinner .append and i cant get any of it to work properly. The 2 areas where i beleive the code needs to be place are as follows: $('#content').children().slice(0, show_per_page).css('display', 'block'); and $('#content').children().fadeOut('slow').slice(start_from, end_on).fadeIn('slow'); Full original code: http://tutsvalley.com/tutorials/making-a-jquery-pagination-system/ Only the second line of code posted here has been altered. Basicly i want to wrap each group of sliced output in a DIV. I hope that makes sense, if you need anymore information please let me know. Any ideas or suggestions on what to try it would be much apreciated as its currently driving me crazy :) Ludz~

  • Javascript callback not firing when AJAX operation complete

    - by MisterJames
    Given the following code on an ASP.NET MVC View: <% using (Ajax.BeginForm("AddCommunity", new AjaxOptions { UpdateTargetId = "community-list", OnSuccess = "BindCommunityHover" })) { %> Add Community: <input type="text" id="communityName" name="communityName" /> <input type="submit" value="Add" /> <% } %> And the following JavaScript method in the file: function BindCommunityHover() { $(".community-item-li").hover( function () { $(this).addClass("communityHover"); }, function () { $(this).removeClass("communityHover"); } ); }; Is there any reason why BindCommunityHover is not being called when the AJAX result comes back? The community-list div is properly updated (the action returns a partial view). I have also tried setting OnComplete (instead of OnSuccess) to no avail. The BindCommunityHover method is called in a $(function(){...}); block when the page first loads, and for all existing .community-item-li elements, it works. The partial result from my controller replaces all items in that div with more of the same class. The OnSuccess method is supposed to fire after the document is updated. Update: k...this gets weird. I added the following to the BindCommunityHover method: alert($(".community-item-li").size()); I'm getting 240 in the alert when the page loads and when the callback fires. So, the callback IS firing, jQuery is matching the elements but not applying the styles...

  • Python socket error on UDP data receive. (10054)

    - by Charles
    I currently have a problem using UDP and Python socket module. We have a server and clients. The problem occurs when we send data to a user. It's possible that user may have closed their connection to the server through a client crash, disconnect by ISP, or some other improper method. As such, it is possible to send data to a closed socket. Of course with UDP you can't tell if the data really reached or if it's closed, as it doesn't care (atleast, it doesn't bring up an exception). However, if you send data and it is closed off, you get data back somehow (???), which ends up giving you a socket error on sock.recvfrom. [Errno 10054] An existing connection was forcibly closed by the remote host. Almost seems like an automatic response from the connection. Although this is fine, and can be handled by a try: except: block (even if it lowers performance of the server a little bit). The problem is, I can't tell who this is coming from or what socket is closed. Is there anyway to find out 'who' (ip, socket #) sent this? It would be great as I could instantly just disconnect them and remove them from the data. Any suggestions? Thanks.
