Target on click

- by 2x2p1p

Hi guys. Look this code: <div> <a href = "#"><span>Click me MAN !</span></a> </div> <script type = "text/javascript"> window.onload = function () { document.body.addEventListener ("click", function (event) { var target = event.target; alert ("Returns \"" + target.nodeName + "\". Just want \"" + target.parentNode.nodeName + "\"") }, false); } </script> You can see the element "span" inside a "link", when the "link" is clicked the current target is the same "span". How can the "event.target" return "link" instead of "span". Thanks and no, I don't want to use "parentNode".

Jquery effect problem : How to detect if mouseover is triggered by scroll ?

- by Crupuk

Hello, I have another problem, and because the reply is to fast here i come back again !! I would like to use "key navigation" and for that, i use the keypress event with down/up key ) When my mouse is over a div (div who's contenaing a big table) and i pull the down key : i scroll to next td + change css style + remove the current style And again, for each event.. So, because my mouse is over the main div, each time i scroll (auto) to a element, the mouseover event is triggered .. And so, the effect is missed.. This is the perfect script : User use keyboard navigation : Mouseover is disabled (so style change only with up/down key) User don't use keyboard : mouseover change the style Could you help me ? The code : $("#content tr").mouseover(function() { $("#content tr.use,#content tr.sel").removeClass("use sel"); $(this).addClass("sel"); }); And the keyboard navigation code : http://pastebin.com/Hgn5Y1FV (Sorry again for my english.. ) Thanks

How to write a jUnit test for this class?

- by flash

Hi, I would like to know what's the best approach to test the method "pushEvent()" in the following class with a jUnit test. My problem is, that the private method "callWebsite()" always requires a connection to the network. How can I avoid this requirement or refactor my class that I can test it without a connection to the network? class MyClass { public String pushEvent (Event event) { //do something here String url = constructURL (event); //construct the website url String response = callWebsite (url); return response; } private String callWebsite (String url) { try { URL requestURL = new URL (url); HttpURLConnection connection = null; connection = (HttpURLConnection) requestURL.openConnection (); String responseMessage = responseParser.getResponseMessage (connection); return responseMessage; } catch (MalformedURLException e) { e.printStackTrace (); return e.getMessage (); } catch (IOException e) { e.printStackTrace (); return e.getMessage (); } } }

How do I handle editing of custom types in a C# datagridview?

- by Ian Hopkinson

I have a datagridview in which one column contains a custom class, which I have set using: dgvPeriods.Columns[1].ValueType = typeof(ExDateTime); It is rigged up to display correctly by handling the CellFormatting event, but I'm unsure what event to handle for cell editing. In the absence of doing anything I get a FormatException as the datagridview tries to convert String to ExDateTime as I try to move focus out of the edited cell. I tried adding type conversion to my ExDateTime custom class: public static implicit operator ExDateTime(string b) { return new ExDateTime(b); } But this this didn't work. I also tried handling the DataError event, but this seems to fire too late. The datagridview is not databound.

Detecting Visual Studio Smart-tags events

- by devoured elysium

Is it possible to detect with VSX when any (or a particular) smart tag event is happening? I mean, every time we rename a variable, for example, a smart tag is available that allows us to change it through a form. I'd like to know if I can access that "text is changing" event. I don't mean to have to check for myself if the text is being changed and such, I'd like to make use of VS event system (if there is one). I gave this example but I'd like to know the "general system" of how smart tags work with VSX. Thanks

HTML 5 drag-drop into wysiwyg editor in Firefox

- by einarq

I have a wysiwyg editor using the HTML 5 drag-drop api to allow the user to place widgets within the page they are editing. When the OnDrop event fires, I prevent the default event, and insert some html within the editor that represents the widget they inserted. I use execCommand("inserthtml", false, html) for this in Firefox. This works fine in IE, but in Firefox the html is not placed in the location where it was dropped. It always gets placed in the location where the previous selection was, which leads me to believe that cancelling the OnDrop event to override the default drop also cancels the selection change. Any ideas on how to solve this? Thanks!

Problem with events and ParseControl

- by Richard Edwards

I'm adding a control (linkbutton) dynamically using ParseControl and it's fine except when I specify an event handler. If I use: Dim c As Control = ParseControl("<asp:LinkButton id=""btnHide"" runat=""server"" text=""Hide"" OnClick="btnHide_Click" />") it correctly adds the control to the page but the click event doesn't fire. If instead I find the control in the controls collection and manually wire up the event it works fine. I've tried loading in both Page_Init and Page_Load and it's the same thing either way. Any ideas?

How to handle all unhandled exceptions when using Task Parallel Library?

- by Buu Nguyen

I'm using the TPL (Task Parallel Library) in .NET 4.0. I want to be able to centralize the handling logic of all unhandled exceptions by using the Thread.GetDomain().UnhandledException event. However, in my application, the event is never fired for threads started with TPL code, e.g. Task.Factory.StartNew(...). The event is indeed fired if I use something like new Thread(threadStart).Start(). This MSDN article suggests to use Task#Wait() to catch the AggregateException when working with TPL, but that is not I want because it is not "centralized" enough a mechanism. Does anyone experience same problem at all or is it just me? Do you have any solution for this?

Windows Platform Installer fails during Orchard Installation

- by nullnvoid

I'm attempting to install Orchard 1.0 on a Windows 7 box. It has only just been released. I downloaded and installed the Windows Platform Installer and attempted to install Orchard. The error message is just that the application has stopped working and asks if I want to debug or close the application. The event log contains a single error: "The event logging service encountered an error while processing an incoming event published from Microsoft-Windows-Security-Auditing." I tried installing MVC3 and it worked without issue. Has anyone experienced a similar problem?

Validating an Autocomplete field in Django

- by anonymous coward

I have models similar to the following: class Band(models.Model): name = models.CharField(unique=True) class Event(models.Model): name = models.CharField(max_length=50, unique=True) bands = models.ManyToManyField(Band) and essentially I want to use the validation capability offered by a ModelForm that already exists for Event, but I do not want to show the default Multi-Select list (for 'bands') on the page, because the potential length of the related models is extremely long. I have the following form defined: class AddEventForm(ModelForm): class Meta: model = Event fields = ('name', ) Which does what is expected for the Model, but of course, validation could care less about the 'bands' field. I've got it working enough to add bands correctly, but there's no correct validation, and it will simply drop bad band IDs. What should I do so that I can ensure that at least one (correct) band ID has been sent along with my form? For how I'm sending the band-IDs with auto-complete, see this related question: http://stackoverflow.com/questions/1528059/

I just want to add an image to show when the video still not playing in and pause. If the video played the image will disappear and if pause the image will appear. Thank You

Quality Design for Asynchronous WCF Services Calls in a Middle-Tier and Returning Data to UI Tier

- by Perplexed

I have a WPF application with a group of asynchronous WCF service calls all mashed into the code behind, complete with event handlers and everything, that I have to refactor to productionize and maintain. I want to separate concerns here for maintainability and all the other good reasons to do this, but I'm not sure exactly how to achieve this. Anybody have any good ideas on how to do this, or at least some links to put me in the right direction? My thinking: Create an "infrastructure" layer and reference the services there. Move the asynchronous event handlers into this layer. When an update is called, I will bubble up my own event with my own derivation of the EventArgs class that contains the data the UI will need. I'll have a fairly coupled hooking of the UI to the infrastructure layer as it will consume events I fire off upon completion of an asynchronous data call.

How can I reshape and aggregate list of tuples in Python?

- by radek

I'm a newb to Python so apologies in advance if my question looks trivial. From a psycopg2 query i have a result in the form of a list of tuples looking like: [(1, 0), (1, 0), (1, 1), (2, 1), (2, 2), (2, 2), (2, 2)] Each tuple represents id of a location where event happened and hour of the day when event took place. I'd like to reshape and aggregate this list with subtotals for each hour in each location, to a form where it looks like: [(1, 0, 2), (1, 1, 1), (1, 2, 0), (2, 0, 0), (2, 1, 1), (2, 3, 3)] Where each touple will now tell me that, for example: in location 1, at hour 0 there were 2 events; in location 1, at hour 1 there was 1 event; and so on... If there were 0 events at certain hour, I still would like to see it, as for example 0 events at 0 hours in location 2: (2, 0, 0) How could I implement it in Python?

Swiz mandates weak encapsulation.

- by Faisal

I just started using Swiz, and, it seems like Swiz forces you to create classes with weak encapsulation. Swiz requires all event handlers to be public in order to mediate events. Assume that component 'A' dispatches a few events, which I want to listen to in component 'B'. Traditionally, I'll just add event listeners on 'A' in 'B' and all the event handlers in 'B' can be kept private. However, if, I am using Swiz, I need to make all the handlers, mediating events, public. Am I missing something here, is there a way to bypass this problem. I really, don't want to pollute the public interface of my class. Thanks.

What is the best way to handle navigation with PRISM?

- by stiank81

Using Prism - what is the best way to handle navigation in a WPF application? And how do you apply this? Are there any best practices? In my application I'm currently using Event Aggregation. Any menu item or other item that should result in navigation in the program will publish an event, and the module responsible for opening the view represented by the published event will do so. This works just fine, but I have a feeling this is not the best way to handle navigation with Prism. Is it?

jQuery UI Element vs Dojo (Dijit) Form Element

- by Muers

Dojo seems to have a useful feature in that it can setup event handlers and default options, etc for Dijit.form elements as it is inserting it into the DOM. For example, Dojo: var slider = new dijit.form.HorizontalSlider({ name: sliderContainerId+'_slider', value: sliderValue, minimum: sliderMax, maximum: sliderMin, onChange: function(value){ // some event handling logic } }, sliderContainerId); However, the jQuery UI Slider traditionally is applied to DOM elements that already exist: $( sliderContainerId ).slider({ value:100, min: 0, max: 500, step: 50, slide: function( event, ui ) { $( "#amount" ).val( "$" + ui.value ); } }); I need to be able to 'programmatically' create new Sliders (and other form elements), but I'm not sure how that could be achieved with the way jQuery is structured? Maybe I'm missing something obvious here.... MTIA

How do I query through a many-to-many relationship using NHibernate Criteria and Lambda Extensions?

- by Brian Kendig

In my database I have a Person table and an Event table (parties, meetings, &c.). This many-to-many relationship is represented through an Invitation table. Each Person can have many Invitations. Each Event can also have many Invitations. If I want a list of Events to which a Person is invited, I can use this HQL query: IQuery query = Session.CreateQuery("SELECT i.Event from Invitation i where i.Person = :p"); query.SetParameter("p", person); return query.List<Person>(); How would I write this query with NHibernate criteria and Lambda Extensions?

Select next element of a given class

- by kevinb92

Hello, I want to hide and show some form in my page. For each form theres a link, and i want that, when i click on this link, it hide and show the nearest form of the link. My code looks like this : $$('.flagLink').each(function(s){ $(s).observe('click', function(event) { // here i want to hide and show the nearest form }); }); I've tried this : $$('.flagLink').each(function(s){ $(s).observe('click', function(event) { $(s).next('form').toggle(); }); }); It works but, i would like to be more precise like : $$('.flagLink').each(function(s){ $(s).observe('click', function(event) { $(s).next('.flagForm').toggle(); }); }); but the .flagForm selector doesnt work.

Flash: Correctly handling click-and-drag outside the browser?

- by David Wolever

What's the correct way to detect, from Flash, when someone has started a drag within the browser (eg, a MOUSE_DOWN event), dragged the mouse outside the browser window, released the button, then moved the mouse back over the browser? For example (assuming StackOverflow was a Flash application): I've tried the "obvious" thing, checking event.buttonDown in the MOUSE_MOVE handler, but even though the mouse button is up, event.buttonDown is true in step 2 (above). So, is there any other way to check the "real" status of the mouse button? Or any other way to handle this situation?

Unexpected cross threading issue

- by haughtonomous

I'm trying to do something very simple in principal, but I keep getting a cross-threading exception which has me stumped because I'm not setting out to use multiple threads. I have a Windows Forms application. It launches another Windows Forms application (using the System.Diagnostics.Process class) , and catches the Exited event when that application is closed. My application event handler then tries to copy text from the clipboard to a control on the current displayed form. At this point a Cross-threading exception is thrown. I assume that the problem is that the event from the closing application is in another thread (I'm outside my comfort zone here, so bear with me), so the question boils down to "How do I prevent this exception?" I'm somewhat constrained into having to copy from the clipboard, but I could launch the other application a different way if that would solve the problem.

C# : Redirect console application output : How to flush the output?

- by user93422

I am spawning external console application and use async output redirect. as shown in this SO post My problem is it seems that the spawned process needs to produce certain amount of output before I get the OutputDataReceived event notification. I want to receive the OutputDataReceived event as soon as possible. I have a bare-bones redirecting application, and here are some observations: 1. When I call a simple 'while(true) print("X");' console application (C#) I receive output event immediately. 2. When I call a 3d party app I am trying to wrap from the command line I see the line-by-line output. 3. When I call that 3d party app from my bare-bone wrapper (see 1) - the output comes in chunks (about one page size). What happens inside that app? FYI: The app in question is a "USBee DX Data Exctarctor (Async bus) v1.0".

How to capture the value change of numericUpDown ctrl real-time in .NET?

- by Carlos_Liu

I have implement the ValueChanged event, but I found it will be triggered only after change the focus from numericUpDown to other control or by clicking the up/down arrow. Inputting the value in the control will not trigger ValueChanged event. What I did now is adding an KeyDown event and judge if the input value is numeric (can not include SHIFT/CTRL/ALT key); but there is another case need to be involved: the user can paste value into the numericUpDown ctrl What I need is : When I was typing numeric value (only numeric) in the numericUpDown ctrl, it will known the content has been changed; When pasted a numeric value into the ctrl, it also kowns the content changed

NHibernate auditing in disconnected mode

- by Ciaran

I'm developing an app with a Silverlight UI, transferring my domain objects over WCF and persisting them via NHibernate. I'm therefore working with NHibernate in a disconnected mode. I'm already using the NHibernate PreUpdate and PreInsert EventListeners to perform some metadata operations (updating Create/Update date, created/updated by etc) and they are working fine. I now have a requirement to perform data logging on some of my domain objects. So I will need to have an audit table that has a before-save and after-save state of certain entities. I had wanted to use the @event.Persister.OldState and @event.Persister.NewState to perform this logging, but because I am in a disconnected scenario (using different Sessions from when data is retrieved to when it is persisted), @event.Persister.OldState is null when I am saving my changes back to the database. How is anyone else doing data logging in a disconnected scenario with NHibernate?
