  • Are vb.net eventArgs maintained at a "system" level?

    - by GregH
    I have a custom developed control I am using that somebody else wrote. For some reason, when the control was written, they did not write an event handler for the "mouseDown" event so when I mouseDown on the control, no event is fired. What I am basically trying to do is capture which mouse button (left or right) is pressed when the control is clicked on. Is there any sort of system level objects that maintain system state (including which mouse buttons are currently being pressed regardless of the control being clicked upon?)

  • Are there web frameworks/tools that optimize for speed of development?

    - by Ahmet Yildirim
    I've been a PHP web developer for about 2 and a half years now. I have started using CodeIgniter framework to shorten development process a while ago. I developed 4 websites using CodeIgniter. It has been really tiring and boring due to code-repetition. Code repetition was vast on form handling functions in controllers.So in my last project , i developed a general form input handling function.This lead a realisation that it could get even faster by more automation. What i think i lack in my development is using CRUD & Code Generation tools. But i am wondering if there is any other utilities that shortens development process. Which web development language or framework more inclined towards code generation utilities?

  • Unique JQuery Events for a Class

    - by Daniel Macias
    I am trying to create a class that can send a unique jQuery event. Example: function Bomb(id) { this.evnt = $.Event("BOOM!_" + id); this.detonate = function() { $(document).trigger(evnt); }; } var firecracker = new Bomb(); var nuclearbomb = new Bomb(); $(document).bind(firecracker.evnt.type, function(){ // It's the fourth of july!!! }); $(document).bind(nuclearbomb.evnt.type, function(){ // We're dead }); firecracker.detonate(); nuclearbomb.detonate(); How can I create a unique event within the Bomb class without having to pass in an ID to create a unique event string for the class?

  • do I need to close an audio Clip?

    - by Michael
    have an application that processes real-time data and is supposed to beep when a certain event occurs. The triggering event can occur multiple times per second, and if the beep is already playing when another event triggers the code is just supposed to ignore it (as opposed to interrupting the current beep and starting a new one). Here is the basic code: Clip clickClip public void prepareProcess() { super.prepareProcess(); clickClip = null; try { clipFile = new File("C:/WINDOWS/Media/CHIMES.wav"); ais = AudioSystem.getAudioInputStream(clipFile); clickClip = AudioSystem.getClip(); clickClip.open(ais); fileIsLoaded = true; } catch (Exception ex) { clickClip = null; fileIsLoaded = false; } } public void playSound() { if (fileIsLoaded) { if ((clickClip==null) || (!clickClip.isRunning())) { try { clickClip.setFramePosition(0); clickClip.start(); } catch (Exception ex) { System.out.println("Cannot play click noise"); ex.printStackTrace(); } } } The prepareProcess method gets run once in the beginning, and the playSound method is called every time a triggering event occurs. My question is: do I need to close the clickClip object? I know I could add an actionListener to monitor for a Stop event, but since the event occurs so frequently I'm worried the extra processing is going to slow down the real-time data collection. The code seems to run fine, but my worry is memory leaks. The code above is based on an example I found while searching the net, but the example used an actionListener to close the Clip specifically "to eliminate memory leaks that would occur when the stop method wasn't implemented". My program is intended to run for hours so any memory leaks I have will cause problems. I'll be honest: I have no idea how to verify whether or not I've got a problem. I'm using Netbeans, and running the memory profiler just gave me a huge list of things that I don't know how to read. This is supposed to be the simple part of the program, and I'm spending hours on it. Any help would be greatly appreciated! Michael

  • Entity with Guid ID is not inserted by NHibernate

    - by DanK
    I am experimenting with NHibernate (version 2.1.0.4000) with Fluent NHibernate Automapping. My test set of entities persists fine with default integer IDs I am now trying to use Guid IDs with the entities. Unfortunately changing the Id property to a Guid seems to stop NHibernate inserting objects. Here is the entity class: public class User { public virtual int Id { get; private set; } public virtual string FirstName { get; set; } public virtual string LastName { get; set; } public virtual string Email { get; set; } public virtual string Password { get; set; } public virtual List<UserGroup> Groups { get; set; } } And here is the Fluent NHibernate configuration I am using: SessionFactory = Fluently.Configure() //.Database(SQLiteConfiguration.Standard.InMemory) .Database(MsSqlConfiguration.MsSql2008.ConnectionString(@"Data Source=.\SQLEXPRESS;Initial Catalog=NHibernateTest;Uid=NHibernateTest;Password=password").ShowSql()) .Mappings(m => m.AutoMappings.Add( AutoMap.AssemblyOf<TestEntities.User>() .UseOverridesFromAssemblyOf<UserGroupMappingOverride>())) .ExposeConfiguration(x => { x.SetProperty("current_session_context_class","web"); }) .ExposeConfiguration(Cfg => _configuration = Cfg) .BuildSessionFactory(); Here is the log output when using an integer ID: 16:23:14.287 [4] DEBUG NHibernate.Event.Default.DefaultSaveOrUpdateEventListener - saving transient instance 16:23:14.291 [4] DEBUG NHibernate.Event.Default.AbstractSaveEventListener - saving [TestEntities.User#<null>] 16:23:14.299 [4] DEBUG NHibernate.Event.Default.AbstractSaveEventListener - executing insertions 16:23:14.309 [4] DEBUG NHibernate.Event.Default.AbstractSaveEventListener - executing identity-insert immediately 16:23:14.313 [4] DEBUG NHibernate.Persister.Entity.AbstractEntityPersister - Inserting entity: TestEntities.User (native id) 16:23:14.321 [4] DEBUG NHibernate.AdoNet.AbstractBatcher - Opened new IDbCommand, open IDbCommands: 1 16:23:14.321 [4] DEBUG NHibernate.AdoNet.AbstractBatcher - Building an IDbCommand object for the SqlString: INSERT INTO [User] (FirstName, LastName, Email, Password) VALUES (?, ?, ?, ?); select SCOPE_IDENTITY() 16:23:14.322 [4] DEBUG NHibernate.Persister.Entity.AbstractEntityPersister - Dehydrating entity: [TestEntities.User#<null>] 16:23:14.323 [4] DEBUG NHibernate.Type.StringType - binding null to parameter: 0 16:23:14.323 [4] DEBUG NHibernate.Type.StringType - binding null to parameter: 1 16:23:14.323 [4] DEBUG NHibernate.Type.StringType - binding 'ertr' to parameter: 2 16:23:14.324 [4] DEBUG NHibernate.Type.StringType - binding 'tretret' to parameter: 3 16:23:14.329 [4] DEBUG NHibernate.SQL - INSERT INTO [User] (FirstName, LastName, Email, Password) VALUES (@p0, @p1, @p2, @p3); select SCOPE_IDENTITY();@p0 = NULL, @p1 = NULL, @p2 = 'ertr', @p3 = 'tretret' and here is the output when using a Guid: 16:50:14.008 [4] DEBUG NHibernate.Event.Default.DefaultSaveOrUpdateEventListener - saving transient instance 16:50:14.012 [4] DEBUG NHibernate.Event.Default.AbstractSaveEventListener - generated identifier: d74e1bd3-1c01-46c8-996c-9d370115780d, using strategy: NHibernate.Id.GuidCombGenerator 16:50:14.013 [4] DEBUG NHibernate.Event.Default.AbstractSaveEventListener - saving [TestEntities.User#d74e1bd3-1c01-46c8-996c-9d370115780d] This is where it silently fails, with no exception thrown or further log entries. It looks like it is generating the Guid ID correctly for the new object, but is just not getting any further than that. Is there something I need to do differently in order to use Guid IDs? Thanks, Dan.

  • Implementing Drag and Drop using MouseListener for custom Components

    - by Chris Lieb
    I am working on a school assignment that requires me to be able to pick up a tile, drag it to a location, then drop it there. I was able to get this working using TransferHandler and a bunch of stuff from the dnd package, but this is not an acceptable way to perform this action for this assignment according to the professor. So, I am trying to achieve the same effect using the MouseListener interface. The basic setup is this: I have a JPanel-derived class called LocationView that contains JLabel-dervived instances of TileView. I need to get events that give me the LocationView that has the mouse pressed on and the LocationView that has the mouse released on. I am proxying mouse events through the TileView to its containing LocationView so that I can properly handle the mousePressed event. I added System.out.println()'s to the mouse listeners for mousePressed and mouseReleased to both LocationView and TileView so that I could observe the events that were being generated. To my surprise, pressing the mouse on Tile A in Location A, then dragging to Location B and releasing would generate a mouse released event for both Tile A and Location A, but not for Location B. I need the mouse released event triggered for only Location B. To try to work around this, I tried implementing a glass pane based off of the FinalGlassPane found at http://weblogs.java.net/blog/2006/09/20/well-behaved-glasspane. After adding the glass pane and adding an event listener for it, I can see that the mouse events are indeed filtering through the glass pane, but the mouse released event is still only being called on the item the mouse was clicked on. Is there a way to have mousePressed and mouseReleased events associated with the same drag action be called on separate components?

  • jquery js how to avoid massive onmouseover onmouseout firing

    - by stephan
    i have a table with some columns. in each of them is a picture where i have a onmouseover onmouseout event on it, which show a message in a div and hide the msg. my problem is - after a user goes quick from left to right (and moving) over a lot o images. all mouseover/out events of the images where executed, which looks stupid... is it possible to rearrange the internal event stack to avoid this? so that he executes only the current (mostly the first event) - and than the last one, if it is not same type eg. if mouseover over first image is executed and mouse moving position stops over an image 3times next the first one. i can avoid all other events firing, because the mouse stopped over an image and the mouseover is like the one where i stopped with the mouse. how can i avoid this multiple event firing?!

  • How doe we name test methods where we are checking for more than one condition?

    - by Sandbox
    I follow the technique specified in Roy Osherove's The Art Of Unit Testing book while naming test methods - MethodName_Scenario_Expectation. It suits perfectly well for my 'unit' tests. But,for tests that I write in 'controller' or 'coordinator' class, there isn't necessarily a method which I want to test. For these tests, I generate multiple conditions which make up one scenario and then I verify the expectation. For example, I may set some properties on different instances, generate an event and then verify that my expectations from controller/coordinator is being met. Now, my controller handles events using a private event handler. Here my scenario is that, I set some properties, say 3 condition1,condition2 and condition3 Also, my scenario includes an event is raised I don't have a method name as my event handler is private. How do I name such a test method?

  • date comparisons in Rails

    - by aressidi
    Hi there, I'm having trouble with a date comparison in a named scope. I'm trying to determine if an event is current based on its start and end date. Here's the named scope I'm using which kind of works, though not for events that have the same start and end date. named_scope :date_current, :conditions => ["Date(start_date) <= ? AND Date(end_date) >= ?", Time.now, Time.now] This returns the following record, though it should return two records, not one... >> Event.date_current => [#<Event id: 2161, start_date: "2010-02-15 00:00:00", end_date: "2010-02-21 00:00:00", ...] What it's not returning is this as well >> Event.find(:last) => #<Event id: 2671, start_date: "2010-02-16 00:00:00", end_date: "2010-02-16 00:00:00", ...> The server time seems to be in UTC and I presume that the entries are being stored in the DB in UTC. Any ideas as to what I'm doing wrong or what to try? Thanks!

  • How come this image won't resize to fit the sprite?

    - by George Edison
    I have this snippet of ActionScript code that is supposed to resize an image to fit the sprite: package { import flash.display.Sprite; import flash.display.Bitmap; import flash.events.Event; public class Main extends Sprite { [Embed(source = 'img.png')] private var TheImage:Class; public static const TheImageWidth:Number = 1300; public static const TheImageHeight:Number = 1300; public function Main():void { if (stage) init(); else addEventListener(Event.ADDED_TO_STAGE, init); } private function init(e:Event = null):void { removeEventListener(Event.ADDED_TO_STAGE, init); // entry point var image:Bitmap = new TheImage(); addChild(image); image.scaleX = width / TheImageWidth; image.scaleY = height / TheImageHeight; } } } Why isn't it working?

  • OSMF - add an actionscript cuepoint to a video?

    - by redconservatory
    I'm trying to add a cuepoint to a video using OSMF. I built an OSMF video player, and I'd like to use this instead of the FLVPlayback component, which seems like the only way to add an actionscript cuepoint? Anyhow, I created a cuepoint by writing this: var cuePoint:CuePoint = new CuePoint(CuePointType.ACTIONSCRIPT, 1, "good point", null); videoElement.addEventListener(MediaElementEvent.METADATA_ADD, onMetadataAdd); trace(cuePoint.time); The cuepoint time traced out to "1" (successful). I then took this code from the documentation, thinking it would help trace the cuepoint when I published my movie (to test the video) private function onMetadataAdd(event:MediaElementEvent):void { if (event.namespaceURL == CuePoint.DYNAMIC_CUEPOINTS_NAMESPACE) { var timelineMetadata:TimelineMetadata = videoElement.getMetadata(CuePoint.DYNAMIC_CUEPOINTS_NAMESPACE) as TimelineMetadata; timelineMetadata.addEventListener(TimelineMetadataEvent.MARKER_TIME_REACHED, onCuePoint); } } private function onCuePoint(event:TimelineMetadataEvent):void { var cuePoint:CuePoint = event.marker as CuePoint; trace("Cue Point at " + cuePoint.time); } However, I don't get a trace message when the video hits 1 second. Can anyone help me?

  • Display message when user leaves site

    - by Brian Rasmusson
    Hi, I'm looking for a way to display a message to the user if he leaves my site after only viewing one page. I found this (http://www.pgrs.net/2008/1/30/popup-when-leaving-website) clever solution, but it has a few flaws: staying_in_site = false; Event.observe(document.body, 'click', function(event) { if (Event.element(event).tagName == 'A') { staying_in_site = true; } }); window.onunload = popup; function popup() { if(staying_in_site) { return; } alert('I see you are leaving the site'); } It displays the message also when refreshing the page or using the back button. Do you know a better solution or how to fix it in the above code? I'm no javascript master :) My intention is to add the code on very specific landing pages only, and display the message when people leave the page without downloading my trial software or reading other pages on my site.

  • Why am I getting 'Argument count mismatch' error here?

    - by Leon
    I have a Document class, Intro class and Nav class. The Intro class runs first, then sends a custom dispatch event to run the Nav class, but I'm getting this error: removed Intro ArgumentError: Error #1063: Argument count mismatch on com.secrettowriting.StanPlayer.ui::Navigation/addNav(). Expected 0, got 1. at flash.events::EventDispatcher/dispatchEventFunction() at flash.events::EventDispatcher/dispatchEvent() at com.secrettowriting.StanPlayer.display::Intro/removeIntro() at flash.utils::Timer/_timerDispatch() at flash.utils::Timer/tick() The addNav function in the Navigation class should expect 0 arguments/variables and I'm not sending any arguments/variables to it, which is why I'm confused as to why it's saying I'm getting 1.

  • Edit the opposite side of a many to many relationship with django generic form

    - by Ed
    I have two models: class Actor(models.Model): name = models.CharField(max_length=30, unique = True) event = models.ManyToManyField(Event, blank=True, null=True) class Event(models.Model): name = models.CharField(max_length=30, unique = True) long_description = models.TextField(blank=True, null=True) In a previous question: http://stackoverflow.com/questions/2503243/django-form-linking-2-models-by-many-to-many-field, I created an EventForm with a save function: class EventForm(forms.ModelForm): class Meta: model = Event def save(self, commit=True): instance = forms.ModelForm.save(self) instance.actors_set.clear() for actor in self.cleaned_data['actors']: instance.actors_set.add(actors) return instance This allowed me to add m2m links from the other side of the defined m2m connection. Now I want to edit the entry. I've been using a generic function: def generic_edit(request, modelname, object_id): modelname = modelname.lower() form_class = form_dict[modelname] return update_object(request, form_class = form_class, object_id = object_id, template_name = 'createdit.html' ) but this pulls in all the info except the many-to-many selections saved to this object. I think I need to do something similar to this: http://stackoverflow.com/questions/1700202/editing-both-sides-of-m2m-in-admin-page, but I haven't figured it out. How do I use the generic update_object to edit the other side of many-to-many link?

  • BackgroundWorker RunWorkerCompleted in a Component

    - by Sphynx
    I'm familiar with the following: "If the operation raises an exception that your code does not handle, the BackgroundWorker catches the exception and passes it into the RunWorkerCompleted event handler, where it is exposed as the Error property of System.ComponentModel.RunWorkerCompletedEventArgs. If you are running under the Visual Studio debugger, the debugger will break at the point in the DoWork event handler where the unhandled exception was raised." However, I've encountered a weird glitch. In my component, there's an instance of BackgroundWorker. Even though it's not running in the debugger, the exception remains unhandled by the worker. Even simplified code produces an unhandled exception (and RunWorkerCompleted doesn't fire): Throw New ArgumentException("Test") The main thing is the code of RunWorkerComplete: RaiseEvent UpdateComplete(Me, New AsyncCompletedEventArgs(e.Error, e.Cancelled, e.Result)) I need the component to expose the worker exception through a public event. If I remove the RaiseEvent call, the exception becomes handled by the worker, and accessible through e.Error. Apparently, raising an event causes the worker to miss the exception. How can that be?

  • Why my events aren't registered after postback?

    - by lucian.jp
    I have a problem where I have a page with a checkbox : <asp:CheckBox runat="server" ID="chkSelectAll" OnCheckedChanged="chkSelectAll_CheckedChanged" EnableViewState="true" Text='<%# CommonFunctions.GetText(Page, "CreateTask", "chkSelectAll.text") %>' AutoPostBack="true" /> First I had the problem that when the event was raised the checkbox wasn't keeping the checked property value. This is still strange because nowhere in the application we set the EnableViewState to false and by default it should be true. Well this behavior was fixed by puting EnableViewState="true". So now, I have a checkbox that when I first load the page, wworks correctly. I check the box, the event is raised Checked property valu is good and the method is executed. Postback completes and renders the page. I check the box back to false, the event is not triggered and the page is reloaded with the previous data but the Checked Property stays at true. So after the first postback I seem to loose behavior of event and ViewState. We suspect the fact that we move dynamically the controls in the page (See answer here) But this suspicion doesn't explain why everything works perfectly after the first load and stops working after first PostBack. EDIT CODE SAMPLE I created a test project where you can experience my problem. At load if you check any checkbox both raise their respective event. After postback only the second raise both events. I seem to have a problem when I register the events after moving control.

  • Swing's KeyListener and multiple keys pressed at the same time.

    - by Negai
    Hi everyone, is there any conventional way in swing of tracking down the events, when two keyboard keys are pressed at the same time? I have a couple of ideas e.g. remembering the key and event generation time so that we could in a consecutive event handler invocation check the time difference between these two events and decide, whether it's a two-button event or not. Phew. But it looks like a kludge. Thanks in advance.

  • jQuery hide/show div working in Opera and Chrome but not IE/Firefox

    - by injekt
    Hey guys, the following snippet of jQuery code seems to work fine in Google Chrome and Opera, but nothing happens when I try hiding/showing the related div in Internet Explorer or Firefox. Any ideas? $(function() { $(".paste-meta-small .right a.collapse").click(function(event) { $(this).parents(".paste-meta-small").next(".highlight").toggle(500); $(this).text($(this).text() == 'show' ? 'hide' : 'show'); event.preventDefault(); }) }) $(function() { $(".highlight-meta a.blog-collapse").click(function(event) { $(this).parents(".highlight-meta").next(".blog-highlight").toggle(500); $(this).text($(this).text() == 'show' ? 'hide' : 'show'); var margin = ($(this).text() == "show" ? "15px" : "0"); $(this).parents(".highlight-meta").css("margin-bottom", margin); event.preventDefault(); }) }) A working example can be found here Thanks in advance

  • iPhone - finding items in current entity that share related item

    - by Pedro
    G'day Folks My core data driven app has an Events entity, essentially a list of times & venues, with a related Acts entity, the names & bios of the acts appearing at those events. I have a table view that shows the event time & venue (as a table section with 1 row), the act name & act bio that works nicely. If that act is appearing at more than one event I'd like to include another table section that lists those events. I think could get that with event.act.events except that it would include the event I'm currently displaying. Can anyone suggest how to get the data I want & exclude the current record? Cheers & TIA, Pedro :) PS... I have not quite 18 hours until the promised time for a prototype of my app to be available for some testers to download.

  • Is there a way to TouchEndInside in Mobile Safari?

    - by Ken Sykora
    I'm trying to determine whether a users does a touchupinside in mobile safari for an iPhone web app. So far I've been unsuccessful. touchend event fires regardless of where the touchup event happens on the screen, and I can't seem to discern that the target has changed by anything in the event argument. Can anyone point me in the right direction on how to capture a touchendinside (vs. touchendoutside) event using javascript? $('a.arrow').bind('touchend',function(e) { console.log($(e.srcElement)); //both of these always return the same element console.log($(e.toElement)); //both of these always return the same element });

  • Why is NavigationHandler.handleNavigation() not forwarding to view ID?

    - by Erik Hermansen
    Inside of a phase listener class that runs during the "RESTORE_VIEW" phase, I have some code like this: public void afterPhase(PhaseEvent event) { FacesContext fc = event.getFacesContext(); NavigationHandler nh = fc.getApplication().getNavigationHandler(); nh.handleNavigation(fc, null, "/a/specific/path/to/a/resource.jspx"); } Navigation to the new URL doesn't work here. The request made will just receive a response from the original JSPX that was navigated to. Code like this works fine: public void afterPhase(PhaseEvent event) { FacesContext fc = event.getFacesContext(); NavigationHandler nh = fc.getApplication().getNavigationHandler(); nh.handleNavigation(fc, null, "OUTCOME_DEFINED_IN_FACES_CONFIG_XML"); } Also the first snippet will work with an IceFaces Faces provider, but not Sun JSF 1.2 which is what I need to use. Is there something I can do to fix the code so it is possible to forward to specific URLs?
