  • how to avoid jQuery UI draggable from also triggering click event

    - by James Tauber
    A have a large div (a map) that is draggable via jQuery UI draggable. The div has child divs which are clickable. My problem is that if you drag the map, on mouse up, the click event is fired on whatever child div you started the drag from. How do I stop the mouse up from triggering the click event if its part of a drag (as opposed to someone just clicking without a drag, in which case the click event is desired).

  • Registering an event from different thread

    - by ET
    Hi, I have a question regarding events in c#. Lets say I have an object obj1 of a class that exposes an event, and this object is running on thread t1. Now on different thread t2, there is another object called obj2 that is registered for the event of obj1. Is it promised that obj2 will get the event when it will be raised? thanks.

  • Handle error at non-UI thread

    - by DreamTeam Mobile
    For some reason unhandled exception which occur at non-UI thread don't handled by App_UnhandledException handler. This approach works well for Windows Phone apps to globally handle, track and analyze exceptions but doesn't work for Windows 8 apps. this.UnhandledException += App_UnhandledException; //doesn't handle private void Button_Click_1(object sender, RoutedEventArgs e) { var task = new Task(() => { throw new NullReferenceException("Test exc in UI thread"); }); task.Start(); } Please, advise.

  • onKeypress Enter Key event on textfield not working in Chrome

    - by rlcrews
    I have a question along the same vein as the one asked here regarding how the enter key is handled in chrome. The effect I am trying to accomplish is to allow the enter key to call a click event of one a button while focus in within the current field. To accomplish this I am using the following code: javascript: <script type="text/javascript"> //attempting to capture keypress for chrome here but this is not working $("#txtContainer").keypress(function (e) { if (e.keyCode == '13') { e.preventDefault(); doClick(buttonname, e); return false; } }); function doClick(buttonName, e) { var key; if (window.event) key = window.event.keyCode; //IE else key = e.which; //firefox if (key == 13) { var btn = document.getElementById(buttonName); if (btn != null) { btn.click(); event.keyCode = 0 } } } </script> within the aspx <form id="form1" runat="server"> <div> <asp:LinkButton ID="newBtn" runat="server" OnClick="btnLogin_Click" Text="ASP Link" /> <asp:TextBox ID="txtContainer" runat="server" Width="100" /> <asp:Label ID="time_lbl" runat="server" /> </div> </form> and within the code behind aspx.cs protected void Page_Load(object sender, EventArgs e) { if (!IsPostBack) { txtContainer.Attributes.Add("onKeyPress", "doClick('" + newBtn.ClientID + "',event)"); } } public void btnLogin_Click(object sender, EventArgs e) { time_lbl.Text = txtContainer.Text; } The above code works fine in FF and IE however chrome continues to submit the entire form vs. capturing the keypress on the enterkey. Thank you for any suggestions.

  • jQuery - Programmatically Trigger Event

    - by Sonny
    I need to programmatically trigger a click event that's being handled by jQuery. Here's the current code: var $thumbs = $('#PhotoGalleryThumbs .tile'); var $zoom = $('#PhotoGallery #PhotoGalleryZoom img'); var $description = $('#PhotoGallery #PhotoGalleryDescription'); $thumbs.click(function(event) { event.preventDefault(); var $thumb = $(this); $thumb.addClass('selected') .siblings().removeClass('selected'); $zoom.attr('src', $thumb.children('a').attr('href')); $description.html($thumb.find('img').attr('alt')); }); I am having a mental block working out how to create a function out of the event handling code and then arbitrarily calling it for an element in the $thumbs object.

  • GeoCoordinateWatcher doesnt fire the event at given intervals

    - by krrishna
    I have the below code which fires the GeoCoordinateWatcher PositionChanged event for every 0.5 meteres .It might be less.But thats my requirement. The issue is when i am walking with phone doesnt fire the event at every 0.5 meters instead it fires the event after 0.5 meters randomly.And sometimes when i move fast it fires few events one after another immediately. Can anybody help me with how to ensure it fires the positionchanged event for every 0.5 meters accurately . watcher = new GeoCoordinateWatcher(GeoPositionAccuracy.Default); if (watcher.Permission == GeoPositionPermission.Granted) { watcher.MovementThreshold = 0.5;//in meters } watcher.PositionChanged += new EventHandler<GeoPositionChangedEventArgs<GeoCoordinate>>(watcher_PositionChanged); // PositionChanged events occur whenever your position changes watcher.StatusChanged += new EventHandler<GeoPositionStatusChangedEventArgs>(watcher_OnStatusChanged); watcher.Start();

  • Event-based interaction between two custom classes

    - by Antenka
    Hello everybody. I have such problem: I have 2 custom components, which have their own nesting hierarchy ... One is container for another. I have to "familiarize them" with each other. The way I'm trying to achieve that is using global events (one side is firing and the other one is catching): Application.application.addEventListener("Hello", function (data:Event):void{ // .. some actions }); //and Application.application.dispatchEvent(new Event(Hello)); Everything is pretty good, but there's one thingy .. when I'm trying to catch the event, I can't access the class, who is catching it. E.g.: Container fires the event. Child caughts it. Then should be created the connection between container and it's child. BUT, the only thing I could acheive is passing a reference to the Container in the DynamicEvent. Is there any chance that I could access the child at the event-handler function. Or maybe there's more elegant way to solve this problem ... Any help would be greately appreciated :)

  • jQuery trigger custom event synchronously?

    - by Miguel Angelo
    I am using the jQuery trigger method to call an event... but it behaves inconsistently. Sometimes it call the event, sometimes it does not. <a href="#" onclick=" $(this).trigger('custom-event'); window.location.href = 'url'; return false; ">text</a> The custom-event has lots of listeners added to it. It is as if the trigger method is not synchronous, allowing the window.location.href be changed before executing the events. And when window.location.href is changed a navigation occurs, interrupting everything. How can I trigger events synchronously? Using jQuery 1.8.1. Thanks! EDIT I have found that the event, when called has a stack trace like this: jQuery.fx.tick (jquery-1.8.1.js:9021) tick (jquery-1.8.1.js:8499) jQuery.Callbacks.self.fireWith (jquery-1.8.1.js:1082) jQuery.Callbacks.fire (jquery-1.8.1.js:974) jQuery.speed.opt.complete (jquery-1.8.1.js:8991) $.customEvent (myfile.js:28) This proves that jQuery trigger method is asynchronous. Oohhh my... =\

  • Mootools event leak

    - by user572263
    The example to demonstrate the issue can be found here: link text The test shows a basic Mootools class that contains an element variable with a click event attached. There’s also a “cleanup” function to remove the event and nullify the element variable. My problem is that when I loop a thousand times to create the “LeakClass” instance and clean it up, it causes a major memory leak like there’s no tomorrow. I tested this on IE8 and Chrome. On the other hand what I’ve noticed is that if I comment out the line that adds the “click” event, the code doesn’t leak. Can somebody please help me structure the class/event in a manner that it doesn’t leak. Thanks in advance.

  • How can I handle this kind of exceptions (in Doctrine)

    - by ppavlovic
    Can you tell me how can I handle this kind of exceptions: Fatal error: Uncaught exception 'Doctrine_Connection_Exception' with message 'PDO Connection Error: SQLSTATE[HY000] [2013] Lost connection to MySQL server at 'reading initial communication packet', system error: 110' in ... It happens when connection with MySQL is lost during query. I need to handle this exception so I can show 500 error page so the crawlers do not cache page, and to redirect user to appropriate "Try again" page. P.S. I have a lot's of code, so I can not go trough all code to put try/catch block. I need something simple and yet effective.

  • c# event and delegate question

    - by user359562
    I want to detach the custom event but could not detach. Please find below I am using -= to detach the event. I assume after this, TextChanged2 method should not be invoked as I have unregistered the event. Let me know if my understanding is wrong. public delegate void TextChangedEventHandler1(object sender, TextBoxargs ta); public event TextChangedEventHandler1 TextChanged1; private void textBox1_TextChanged(object sender, EventArgs e) { this.TextChanged1 -= new TextChangedEventHandler1(TextChanged2); TextChanged2(sender, e); } public void TextChanged2(object sender, EventArgs e) { textBox1.Text = textBox1.Text.ToUpper(); }

  • poll(2) doesn't empty the event queue

    - by sasayins
    Hi, Im using linux as my programming platform. I am using poll(2) to know if my device is triggering an event. The first call of poll is ok, it blocks and wait for the event to happen. But in the second poll function call, it will return but it capture the event. Below are my code ret = poll( fds, 1, 2000); //2 secs timeout if( fds[0].revents & POLLIN && ret > 0) { printf("event occur\n"); } It seems the queue/buffer is not empty, im just assuming. What do you think is the problem? Thanks.

  • Why isn't this working - using :not() with an event handler

    - by james emanon
    I seem to have another issue that I am not conquering. Real simple premise. I have a mousedown event, and basically IF one particular element on the page is clicked, I want nothing to happen, else I want hide() some div. $(function(){ $("document :not(#_ignorelement)").mousedown(function(event){ if($('#_hidethiselement').length){ $('#_hidethiselement').hide(); } }) }) That is not working at all. I also tried the following: $(document).not($("#_ignorelement")).mousedown(function(event){ $(document).not("_ignorelement").mousedown(function(event){ IF I can solve that, curious how I would actually have ":not" encompass the parent div, like so: $().not("_ignoreelement").parent().closest('div').mousedown(function Because the element "_ignorelement" is an anchor tag that is in a div. Wonder how I can use the parent div perhaps, instead of the anchor tag. Anyways, any help would be appreciated.

  • Hosting a website on Heroku.... I know how to, but im running into problems!

    - by Thomas Miller
    I'm starting to learn more on the back-end scale of programing. Recently I started up Heroku for the second or third time. This time I actually installed the Git update to my Mac and installed Heroku in the terminal. I wanted to upload a static html site with the sinatra gem. Everything worked out fine inside the terminal, though I added sinatra after I got everything working and the file with the site hooked up to Heroku. In my logs I did see that I was missing the sinatra gem, so I installed it. My site contains both the proper app.rb and config.ru files. I have nothing showing up online. Just a blank screen! Contacting Heroku on this problem has been very difficult. I get a responce every day, and on every day I respond with a question to the answer that didn't help me at all. 2011-05-18T00:25:20+00:00 app[web.1]: 71.198.0.51 - - [17/May/2011 17:25:20] "GET /favicon.ico HTTP/1.1" 404 18 0.0008 2011-05-18T00:25:20+00:00 heroku[router]: GET pxlc.heroku.com/favicon.ico dyno=web.1 queue=0 wait=0ms service=2ms bytes=313 2011-05-18T00:25:26+00:00 app[web.1]: 71.198.0.51 -

  • Hosting a website on Heroku.... I know how to, but im running into problems!

    - by Thomas Miller
    I'm starting to learn more on the back-end scale of programing. Recently I started up Heroku for the second or third time. This time I actually installed the Git update to my Mac and installed Heroku in the terminal. I wanted to upload a static html site with the Sinatra gem. Everything worked out fine inside the terminal, though I added Sinatra after I got everything working and the file with the site hooked up to Heroku. In my logs I did see that I was missing the Sinatra gem, so I installed it. My site contains both the proper app.rb and config.ru files. I have nothing showing up online. Just a blank screen! Contacting Heroku on this problem has been very difficult. I get a response every day, and on every day I respond with a question to the answer that didn't help me at all. 2011-05-18T00:25:20+00:00 app[web.1]: 71.198.0.51 - - [17/May/2011 17:25:20] "GET /favicon.ico HTTP/1.1" 404 18 0.0008 2011-05-18T00:25:20+00:00 heroku[router]: GET pxlc.heroku.com/favicon.ico dyno=web.1 queue=0 wait=0ms service=2ms bytes=313 2011-05-18T00:25:26+00:00 app[web.1]: 71.198.0.51 -

  • System Account Logon Failures ever 30 seconds

    - by floyd
    We have two Windows 2008 R2 SP1 servers running in a SQL failover cluster. On one of them we are getting the following events in the security log every 30 seconds. The parts that are blank are actually blank. Has anyone seen similar issues, or assist in tracking down the cause of these events? No other event logs show anything relevant that I can tell. Log Name: Security Source: Microsoft-Windows-Security-Auditing Date: 10/17/2012 10:02:04 PM Event ID: 4625 Task Category: Logon Level: Information Keywords: Audit Failure User: N/A Computer: SERVERNAME.domainname.local Description: An account failed to log on.

I installed Network Monitor on this machine and did a filter for Kerberos traffic and found the following which corresponds to the timestamps in the security audit log. A Kerberos AS_Request Cname: CN=SQLInstanceName Realm:domain.local Sname krbtgt/domain.local Reply from DC: KRB_ERROR: KDC_ERR_C_PRINCIPAL_UNKOWN I then checked the security audit logs of the DC which responded and found the following: A Kerberos authentication ticket (TGT) was requested. Account Information: Account Name: X509N:<S>CN=SQLInstanceName Supplied Realm Name: domain.local User ID: NULL SID Service Information: Service Name: krbtgt/domain.local Service ID: NULL SID Network Information: Client Address: ::ffff:10.240.42.101 Client Port: 58207 Additional Information: Ticket Options: 0x40810010 Result Code: 0x6 Ticket Encryption Type: 0xffffffff Pre-Authentication Type: - Certificate Information: Certificate Issuer Name: Certificate Serial Number: Certificate Thumbprint: So appears to be related to a certificate installed on the SQL machine, still dont have any clue why or whats wrong with said certificate. It's not expired etc.

  • Windows Software RAID 5 Drive Failure Notification

    - by Wayne Hartman
    I plan on creating a Windows software RAID 5 array but need to know when a drive goes bum. I don't plan on wanting to check the server every so often, so how can I have an email sent when a drive goes kapüt or otherwise has problems? Keying off the event log would be OK, but how does one set up notifications on it when the exact event ID(s) may not be known?
