  • Hover/Fadeto/Toggle Multiple Class Changing

    - by Slick Willis
    So my problem is rather simple and complex at the same time. I am trying to create links that fade in when you mouseover them and fade out when you mouseout of them. At the same time that you are going over them I would like a pic to slide from the left. This is the easy part, I have every thing working. The image fades and another image slides. I did this by using a hover, fadeto, and toggle("slide"). I would like to do this in a table format with multiple images being able to be scrolled over and sliding images out. The problem is that I am calling my sliding image to a class and when I hover over the letters both images slide out. Does anybody have a solution for this? I posted the code that I used below: <html> <head> <script type='text/javascript' src='http://accidentalwords.squarespace.com/storage/jquery/jquery-1.4.2.min.js'></script> <script type='text/javascript' src='http://accidentalwords.squarespace.com/storage/jquery/jquery-custom-181/jquery-ui-1.8.1.custom.min.js'></script> <style type="text/css"> .text-slide { display: none; margin: 0px; width: 167px; height: 50px; } </style> <script> $(document).ready(function(){ $(".letterbox-fade").fadeTo(1,0.25); $(".letterbox-fade").hover(function () { $(this).stop().fadeTo(250,1); $(".text-slide").toggle("slide", {}, 1000); }, function() { $(this).stop().fadeTo(250,0.25); $(".text-slide").toggle("slide", {}, 1000); }); }); </script> </head> <body style="background-color: #181818"> <table> <tr> <td><div class="letterbox-fade"><img src="http://accidentalwords.squarespace.com/storage/sidebar/icons/A-Letterbox-Selected.png" /></div></td> <td><div class="text-slide"><img src="http://accidentalwords.squarespace.com/storage/sidebar/icons/TEST.png" /></div></td> </tr> <tr> <td><div class="letterbox-fade"><img src="http://accidentalwords.squarespace.com/storage/sidebar/icons/B-Letterbox-Selected.png" /></div></td> <td><div class="text-slide"><img src="http://accidentalwords.squarespace.com/storage/sidebar/icons/TEST.png" /></div></td> </tr> </table> </body> </html>

  • Which languages support class replacement?

    - by Alix
    Hi, I'm writing my master thesis, which deals with AOP in .NET, among other things, and I mention the lack of support for replacing classes at load time as an important factor in the fact that there are currently no .NET AOP frameworks that perform true dynamic weaving -- not without imposing the requirement that woven classes must extend ContextBoundObject or MarshalByRefObject or expose all their semantics on an interface. You can however do this in Java thanks to ClassFileTransformer: You extend ClassFileTransformer. You subscribe to the class load event. On class load, you rewrite the class and replace it. All this is very well, but my project director has asked me, quite in the last minute, to give him a list of languages that do / do not support class replacement. I really have no time to look for this now: I wouldn't feel comfortable just doing a superficial research and potentially putting erroneous information in my thesis. So I ask you, oh almighty programming community, can you help out? Of course, I'm not asking you to research this yourselves. Simply, if you know for sure that a particular language supports / doesn't support this, leave it as an answer. If you're not sure please don't forget to point it out. Thanks so much!

  • Midiplayer stops playing sounds after 16 notes.

    - by user349673
    Hi. I am currently programming a Piano Keyboard editor, much like the one you can find in Cubase, Logic, Reason etc.. I have this big grid, double array new int [13][9], which makes it 13 rows, 9 columns. The first column [0-12][0] is the Keyboard, at the top there's "high C" (midi note 72) and at the bottom there's "low C" (midi note 60). That column is an array of JButtons and when you press for example "low C", note 60 is being played by the Synthesizer. I've gotten this to work pretty OK as for now, but one problem I have is that I can only play 16 notes in a row, then it's like the Synthesizer shuts down or something. Do you guys have ANY idea of what the problem is? A bit of the code: import java.awt.*; import javax.swing.*; import java.awt.event.*; import java.util.*; import javax.sound.midi.*; actionPerformed(ActionEvent ae){ for(int i = 0; i<13; i++){ if(o== instr[i]){//instr is the button array SpelaTangent(i); } } } public void SpelaTangent(int tangent){ int [] klaviatur = new int[13]; for(int i = 0; i<13; i++){ klaviatur[i] = (72-i); } try { Synthesizer synth = MidiSystem.getSynthesizer(); synth.open(); final MidiChannel[] mc = synth.getChannels(); Instrument[] instrument = synth.getDefaultSoundbank().getInstruments(); synth.loadInstrument(instrument[1]); mc[0].noteOn(klaviatur[tangent],350); mc[0].noteOff(klaviatur[tangent],350); } catch (MidiUnavailableException e) {} } Help is very much appreciated!

  • Rails development environment Resque.enqueue does not create jobs

    - by anton evangelatov
    I am having the same problem like Rails custom environment Resque.enqueue does not create jobs , but the solution there doesn't work for me. I'm using Resque for a couple of asynchronous jobs. It works just fine for the staging environment, but for some reason it stopped working on development environment. For example, if I run the following: $ rails c development > Resque.enqueue(MyLovelyJob, 1) Nothing is enqueued. I check Resque using resque-web If I run it on staging - it works just fine. $ rails c staging > Resque.enqueue(MyLovelyJob, 1) I have tried to duplicate the 2 environment, and they seem to use absolutely the same configurations (database.yml , config/environment , etc.), but development is still not working. If I do > Resque.enqueue(UpdateInstancesData, 2) > => true > Resque.info > => { > :pending => 0, > :processed => 0, > :queues => 0, > :workers => 1, > :working => 0, > :failed => 0, > :servers => [ > [0] "redis://127.0.0.1:6379/0" > ], > :environment => "development" > } Any suggestions where to look in order to debug this? I am running the application via foreman. My Procfile looks like: faye: rackup faye.ru -s thin -E production worker1: bundle exec rake resque:work QUEUE=* VERBOSE=1 worker2: bundle exec rake resque:work QUEUE=* VERBOSE=1 clock: bundle exec rake resque:scheduler VERBOSE=1 web: bundle exec rails s For staging, as mentioned, everything works and the log from foreman is: 17:03:42 clock.1 | 2013-06-26 17:03:42 Reloading Schedule 17:03:42 clock.1 | 2013-06-26 17:03:42 Loading Schedule 17:03:42 clock.1 | 2013-06-26 17:03:42 Scheduling logging_test 17:03:42 clock.1 | 2013-06-26 17:03:42 Schedules Loaded 17:03:43 worker2.1 | *** Starting worker ttttt-mbp.local:69573:* 17:03:43 worker2.1 | *** Registered signals 17:03:43 worker2.1 | *** Running before_first_fork hooks 17:03:43 worker1.1 | *** Starting worker ttttt-mbp.local:69572:* 17:03:43 worker1.1 | *** Registered signals 17:03:43 worker2.1 | *** Checking another_queue 17:03:43 worker2.1 | *** Checking anotherqueue 17:03:43 worker2.1 | *** Checking statused 17:03:43 worker2.1 | *** Found job on statused 17:03:43 worker2.1 | *** got: (Job{statused} | LoggingTest | ["57e89a1c1b24ce6866bcf5d0e1c07f01", {}]) 17:06:30 clock.1 | 2013-06-26 17:06:30 queueing LoggingTest (logging_test) 17:06:33 worker1.1 | *** Checking another_queue 17:06:33 worker2.1 | *** Checking another_queue 17:06:33 worker1.1 | *** Checking anotherqueue 17:06:33 worker2.1 | *** Checking anotherqueue 17:06:33 worker1.1 | *** Found job on anotherqueue 17:06:33 worker1.1 | *** got: (Job{anotherqueue} | LoggingTest | ["0d976869a945766e0cfeca83e7349305", {}]) 17:06:33 worker1.1 | *** resque-1.24.1: Processing anotherqueue since 1372259193 [LoggingTest] 17:06:33 worker1.1 | *** Running before_fork hooks with [(Job{anotherqueue} | LoggingTest | ["0d976869a945766e0cfeca83e7349305", {}])] 17:06:33 worker1.1 | *** resque-1.24.1: Forked 69955 at 1372259193 17:06:33 worker2.1 | *** resque-1.24.1: Forked 69956 at 1372259193 17:06:33 worker1.1 | *** Running after_fork hooks with [(Job{anotherqueue} | LoggingTest | ["0d976869a945766e0cfeca83e7349305", {}])] 17:06:33 worker1.1 | JOB :: LoggingTest 17:06:33 worker1.1 | 55555 17:06:33 worker1.1 | *** done: (Job{anotherqueue} | LoggingTest | ["0d976869a945766e0cfeca83e7349305", {}]) whereas for development it doesn't seem to enqueue and then find the job.

  • JQuery checkbox state is updated differently between group click() and $.each(obj.click())

    - by teerapap
    The code below doesn't work in the same behavior. The sequence of click event and calling foo() is different. I want to know why they behave different sequence between call click() and iterate the objects before call click() on each. <script type="text/javascript"> function foo(obj){ alert(obj.id+" ->"+obj.checked); } function clickAll(val){ if (val) { $(":checkbox").click(); } else { $(":checkbox").each(function(i,obj){ obj.click(); }); } } </script> </head> <body> <input type="checkbox" id="check1" onclick="foo(this)" /> a <input type="checkbox" id="check2" onclick="foo(this)" /> b <input type="checkbox" id="check3" onclick="foo(this)" /> c <input type="button" onclick="clickAll(true)" value="click all" /> <input type="button" onclick="clickAll(false)" value="click all each" /> </body>

  • LINQ to Entities question about orderby and null collections.

    - by Chevex
    I am currently developing a forum. I am new to LINQ and EF. In my forum I have a display that shows a list of topics with the most recent topics first. The problem is that "most recent" is relative to the topic's replies. So I don't want to order the list by the topic's posted date, rather I want to order the list by the topic's last reply's posted date. So that topics with newer replies pop back to the top of the list. This is rather simple if I knew that every topic had at least one reply; I would just do this: var topicsQuery = from x in board.Topics orderby x.Replies.Last().PostedDate descending select x; However, in many cases the topic has no replies. In which case I would like to use the topic's posted date instead. Is there a way within my linq query to order by x.PostedDate in the event that the topic has no replies? I'm getting confused by this and any help would be appreciated. With the above query, it breaks on topics with no replies because of the x.Replies.Last() which assumes there are replies. LastOrDefault() doesn't work because I need to access the PostedDate property which also assumes a reply exists. Thanks in advance for any insight.

  • Most efficient method of detecting/monitoring DOM changes?

    - by Graza
    I need an efficient mechanism for detecting changes to the DOM. Preferably cross-browser, but if there's any efficient means which are not cross browser, I can implement these with a fail-safe cross browser method. In particular, I need to detect changes that would affect the text on a page, so any new, removed or modified elements, or changes to inner text (innerHTML) would be required. I don't have control over the changes being made (they could be due to 3rd party javascript includes, etc), so it can't be approached from this angle - I need to "monitor" for changes somehow. Currently I've implemented a "quick'n'dirty" method which checks body.innerHTML.length at intervals. This won't of course detect changes which result in the same length being returned, but in this case is "good enough" - the chances of this happening are extremely slim, and in this project, failing to detect a change won't result in lost data. The problem with body.innerHTML.length is that it's expensive. It can take between 1 and 5 milliseconds on a fast browser, and this can bog things down a lot - I'm also dealing with a large-ish number of iframes and it all adds up. I'm pretty sure the expensiveness of doing this is because the innerHTML text is not stored statically by browsers, and needs to be calculated from the DOM every time it is read. The types of answers I am looking for are anything from the "precise" (for example event) to the "good enough" - perhaps something as "quick'n'dirty" as the innerHTML.length method, but that executes faster.

  • Record the timestamps of slide changes during a live Powerpoint presentation?

    - by StackedCrooked
    I am planning to implement a lecture capture solution. One of the requirements is to record both the presenter and the slideshow. The presenter is recorded with a videocamera obviously, and the slideshow will probably be captured using a tool like Camtasia. Now during playback three components are visible: the presenter, the slides and a table of contents. Clicking a chapter title in the TOC causes the video to navigate to the corresponding section. This means that a mapping must be made between chapter titles and their timestamps in the video. Usually a change of topic is accompanied with a slide change in the Powerpoint presentation. So the timestamps could be deduced from the slidechanges. However, this requires me to detect slide changes during the live presentation. And I don't know how to do that. Anyone here knows how to do detect slide changes? Is there a Powerpoint API where I can connect event handlers or something like that? I'd greatly appreciate your help! Edit This issue is no longer relevant for my current work so this question will not be updated by me. However, you are still free to help others by posting your answers/insights here.

  • Carbon, LSUIElement, and showing a window

    - by James Turner
    I have a Carbon LSUIElement application, which runs in the background (possibly with an icon in the menubar, depending on a pref) and occasionally needs to show a dialog to the user - sometimes in response to a user event, but sometimes in response to a background task failing or similar. (I'm using Qt 4.5, so the application is Carbon based; With Qt 4.6 things will be Cocoa based, but it sounds as if the problem may exist there too). The problem is that when I open a window, and show it, it doesn't get brought to the front. I assume this is an artefect of being an LSUIElement app. Qt uses SelectWindow in Carbon, and [makeKeyAndOrderFront] in Cocoa, to bring a window (and the app) to the front. To work around the problem, I tried going direct to the window server: (the first few steps are to get the WindowID, this will be simpler with Qt-Cocoa, since I can use NSWindow:nativeWindow) WindowRef ref = HIViewGetWindow((HIViewRef) aWidget->winId()); CGSWindow wid = GetNativeWindowFromWindowRef(ref); CGSConnection cid =_CGSDefaultConnection(); CGSOrderWindow(cid, wid, 1 /* above everything */, 0 /* NULL */); This works, sort of - the window comes to the front, but it's not highlighted or keyboard focused. Are there additional steps to fix those issues, or is there a simpler solution to the whole problem?

  • iTextSharp Overlay Image

    - by pennylane
    Hi guys I have an instance where I have a logo image as part of some artwork.. If a user uploads a new logo I have a form field which is larger than the default logo. I then use that form field to position the new image. The problem is I need to set the background colour of that form field to white so that it covers the old logo in the event that the new image is smaller than the old logo.. what I have done is: foreach (var imageField in imageReplacements) { fields.SetFieldProperty(imageField.Key, "bgcolor", iTextSharp.text.Color.WHITE, null); fields.RegenerateField(imageField.Key); PdfContentByte overContent = stamper.GetOverContent(imageField.Value.PageNumber); float[] logoArea = fields.GetFieldPositions(imageField.Key); if (logoArea != null) { iTextSharp.text.Rectangle logoRect = new iTextSharp.text.Rectangle(logoArea[1], logoArea[2], logoArea[3], logoArea[4]); var logo = iTextSharp.text.Image.GetInstance(imageField.Value.Location); if (logo.Width >= logoRect.Width || logo.Height >= logoRect.Height) { logo.ScaleToFit(logoRect.Width, logoRect.Height); } logo.Alignment = iTextSharp.text.Image.ALIGN_LEFT; logo.SetAbsolutePosition(logoRect.Left, logoArea[2] + (logoRect.Height - logo.ScaledHeight) / 2); // left: logoArea[3] - logo.ScaledWidth + (logoRect.Width - logo.ScaledWidth) / 2 overContent.AddImage(logo); } } The problem with this is that the background colour of the field is set to white and the image then doesn't appear.. i remove the SetFieldProperty and RegenerateField commands and the image replacement works fine.. is there a way to set a stacking order on layers?

  • How to force positioned elements to stay withing viewable browser area?

    - by jessegavin
    I have a script which inserts "popup" elements into the DOM. It sets their top and left css properties relative to mouse coordinates on a click event. It works great except that the height of these "popup" elements are variable and some of them extend beyond the viewable area of the browser window. I would like to avoid this. Here's what I have so far <script type="text/javascript"> $(function () { $("area").click(function (e) { e.preventDefault(); var offset = $(this).offset(); var relativeX = e.pageX - offset.left; var relativeY = e.pageY - offset.top; // 'responseText' is the "popup" HTML fragment $.get($(this).attr("href"), function (responseText) { $(responseText).css({ top: relativeY, left: relativeX }).appendTo("#territories"); // Need to be able to determine // viewable area width and height // so that I can check if the "popup" // extends beyond. $(".popup .close").click(function () { $(this).closest(".popup").remove(); }); }); }); }); </script>

  • Please recommend me intermediate-to-advanced Python books to buy.

    - by anonnoir
    I'm in the final year, final semester of my law degree, and will be graduating very soon. (April, to be specific.) But before I begin practice, I plan to take 2 two months off, purely for serious programming study. So I'm currently looking for some Python-related books, gauged intermediate to advanced, which are interesting (because of the subject matter itself) and possibly useful to my future line of work. I've identified 2 possible purchases at the moment: Natural Language Processing with Python. The law deals mostly with words, and I've quite a number of ideas as to where I might go with NLP. Data extraction, summaries, client management systems linked with document templates, etc. Programming Collective Intelligence. This book fascinates me, because I've always liked the idea of machine learning (and I'm currently studying it by the side too, for fun). I'd like to build/play around with Web 2.0 applications; and who knows if I can apply some of the things I learn to my legal work. (E.g. Playground experiments to determine how and under what circumstances judges might be biased, by forcing algorithms to pore through judgments and calculate similarities, etc.) Please feel free to criticize my current choices, but do at least offer or recommend other books that I should read in their place. My budget can deal with 4 books, max. These books will be used heavily throughout the 2 months; I will be reading them back to back, absorbing the explanations given, and hacking away at their code. Also, the books themselves should satisfy 2 main criteria: Application. The book must teach how to solve problems. I like reading theory, but I want to build things and solve problems first. Even playful applications are fine, because games and experiments always have real-world applications sooner or later. Readability. I like reading technical books, no matter how difficult they are. I enjoy the effort and the feeling that you're learning something. But the book shouldn't contain code or explanations that are too cryptic or erratic. Even if it's difficult, the book's content should be accessible with focused reading. Note: I realize that I am somewhat of a beginner to the whole programming thing, so please don't put me down. But from experience, I think it's better to aim up and leave my comfort zone when learning new things, rather than to just remain stagnant the way I am. (At least the difficulty gives me focus: i.e. if a programmer can be that good, perhaps if I sustain my own efforts I too can be as good as him someday.) If anything, I'm also a very determined person, so two months of day-to-night intensive programming study with nothing else on my mind should, I think, give me a bit of a fighting chance to push my programming skills to a much higher level.

  • WPF Usercontrol with textboxes

    - by benPearce
    I have a WPF user control with a number of textboxes, this is hosted on a WPF window. The textboxes are not currently bound but I cannot type into any of them. I have put a breakpoint in the KeyDown event of one of the textboxes and it hits it fine and I can see the key I pressed. The textboxes are declared as <TextBox Grid.Row="3" Grid.Column="4" x:Name="PostcodeSearch" Style="{StaticResource SearchTextBox}" KeyDown="PostcodeSearch_KeyDown"/> The style is implemented as <Style x:Key="SearchTextBox" TargetType="{x:Type TextBox}"> <Setter Property="Control.Margin" Value="2"/> <Setter Property="Height" Value="20"/> <Setter Property="Width" Value="140"/> <Setter Property="HorizontalAlignment" Value="Left"/> </Style> I am hoping I have overlooked something obvious. EDIT: I only added the KeyDown and KeyUp events just to prove that the keys presses were getting through. I do not have any custom functionality.

  • Low-level Keyboard Hooks/SendInput with Winkey+L possible? (workstation lockout is intercepted in Vi

    - by Brian Jorgensen
    I work on a project called UAWKS (Unofficial Apple Wireless Keyboard Support) that helps Windows users use Apple's bluetooth keyboard. One of the main goals of UAWKS is to swap the Cmd key (which behaves as Winkey in Windows) with Ctrl, allowing users to do Cmd+C for copy, Cmd+T for new tab, etc. It is currently developed using AutoHotkey, which worked pretty well under Windows XP. However, on Vista and Windows 7, Cmd+L causes problems: Regardless of low-level keyboard hooks, Winkey+L is always intercepted by Windows and normally locks the workstation... You can disable workstation locking with this registry hack, but pressing Winkey+L still can't be rebound in AHK Pressing Winkey+L leaves Winkey in the Keydown state until the next (additional) Winkey Up. Simulating a Keyup event doesn't seem to work either! It seems that Winkey+L is a special chord that messes everything else up. I've looked through the AHK source code, and they try to address this problem in SendKey() in keyboard_mouse.cpp (near line 883 in v1.0.48.05), but it doesn't work. I wrote up my own low-level keyboard hook application in C#, and I see the same problem. Has anyone else run into this? Is there a workaround?

  • NetBeans Platform - how to refresh the property sheet view of a node?

    - by I82Much
    Hi all, I am using the PropertySheetView component to visualize and edit the properties of a node. This view should always reflect the most recent properties of the object; if there is a change to the object in another process, I want to somehow refresh the view and see the updated properties. The best way I was able to do this is something like the following (making use of EventBus library to publish and subscribe to changes in objects): public DomainObjectWrapperNode(DomainObject obj) { super (Children.LEAF, Lookups.singleton(obj)); EventBus.subscribe(DomainObject.class, this); } public void onEvent(DomainObject event) { // Do a check to determine if the updated object is the one wrapped by this node; // if so fire a property sets change firePropertySetsChange(null, this.getPropertySets()); } This works, but my place in the scrollpane is lost when the sheet refreshes; it resets the view to the top of the list and I have to scroll back down to where I was before the refresh action. So my question is, is there a better way to refresh the property sheet view of a node, specifically so my place in the property list is not lost upon refresh?

  • WPF ProgressBar - TargetParameterCountException

    - by Dr_Asik
    I am making my first WPF application, where I use the Youtube .NET API to upload a video to Youtube using the ResumableUploader. This ResumableUploader works asynchronously and provides an event AsyncOperationProgress to periodically report its progress percentage. I want a ProgressBar that will display this progress percentage. Here is some of the code I have for that: void BtnUpload_Click(object sender, RoutedEventArgs e) { // generate video uploader = new ResumableUploader(); uploader.AsyncOperationCompleted += OnDone; uploader.AsyncOperationProgress += OnProgress; uploader.InsertAsync(authenticator, newVideo.YouTubeEntry, new UserState()); } void OnProgress(object sender, AsyncOperationProgressEventArgs e) { Dispatcher.BeginInvoke((SendOrPostCallback)delegate { PgbUpload.Value = e.ProgressPercentage; }, DispatcherPriority.Background, null); } Where PgbUpload is my progress bar and the other identifiers are not important for the purpose of this question. When I run this, OnProgress will be hit a few times, and then I will get a TargetParameterCountException. I have tried several different syntax for invoking the method asynchronously, none of which worked. I am sure the problem is the delegate because if I comment it out, the code works fine (but the ProgressBar isn't updated of course). Thanks for any help.

You can however do this with the JVM thanks to ClassFileTransformer: You extend ClassFileTransformer. You subscribe to the class load event. On class load, you rewrite the class and replace it. All this is very well, but my project director has asked me, quite in the last minute, to give him a list of frameworks (and associated languages) that do / do not support class replacement. I really have no time to look for this now: I wouldn't feel comfortable just doing a superficial research and potentially putting erroneous information in my thesis. So I ask you, oh almighty programming community, can you help out? Of course, I'm not asking you to research this yourselves. Simply, if you know for sure that a particular framework supports / doesn't support this, leave it as an answer. If you're not sure please don't forget to point it out. Thanks so much!

  • Advice on a simple Windows Form

    - by Austin Hyde
    I have a VERY simple windows form that the user uses to manage "Stores". Each store has a name and number, and is kept in a corresponding DB table. The form has a listbox of stores, an add button that creates a new store, a delete button, and an edit button. Beside those I have text boxes for the name and number, and save/cancel buttons. When the user chooses a store from the list box, and clicks 'edit', the textboxes become populated and save/cancel become active. When the user clicks 'add', I create a new Store, add it to the listbox, activate the textboxes and save/cancel buttons, then commit it to the database when the user clicks 'save', or discards it when the user clicks 'cancel'. Right now, my event system looks like this (in psuedo-code. It's just shorter that way.) add->click: store = new Store() listbox.add(store) populateAndEdit(store) delete->click: store = listbox.selectedItem db.deleteOnSubmit(store) listbox.remove(store) db.submit() edit->click: populateAndEdit(listbox.selectedItem) save->click: parseAndSave(listbox.selectedItem) db.submit() disableTexts() cancel->click: disableTexts() The problem is in how I determine if we are inserting a new Store, or updating an existing one. The obvious solution to me would be to make it a "modal" process - that is, when I click edit, I go into edit mode, and the save button does things differently than if I were in add mode. I know I could make this more MVC-like, but I don't really think this simple form merits the added complexity. I'm not very experienced with winforms, so I'm not sure if I even have the right idea for how to tackle this. Is there a better way to do this? I would like to keep it simple, but usable.

  • Hyperlink in Silverlight AccordionItem HeaderTemplate

    - by Charlie Brown
    I have created a HeaderTemplate for my accordions where I want to display a text block on one side of the header and a hyperlink on the right side. The display is working correctly, but the click event is not called when the user clicks, I'm guessing b/c the header itself is trapping the click for expand/contract. <layoutToolkit:Accordion> <layoutToolkit:AccordionItem IsSelected="True"> <layoutToolkit:AccordionItem.HeaderTemplate> <DataTemplate> <StackPanel Orientation="Horizontal" Height="20"> <TextBlock Margin="0,0,700,0">Cancel Postcards</TextBlock> <HyperlinkButton Content="Next Call" Foreground="Blue" Click="NextCancel_Click" /> </StackPanel> </DataTemplate> </layoutToolkit:AccordionItem.HeaderTemplate> ..... more code .... Is there a way to get the hyperlink to respond to events without practically creating a new control?

  • How to start animation when I'm pressing on item of ListView?

    - by Ares
    I want to implement next functional: When I'm tapping on ListView's item, it's turning into red color. If I release it has to reverse color back. I made transition drawable and set it as item's background. I tried to implement SimpleGestureListener and started animation on onDown and reversed it on onSingleTapUp events, but it doesn't give me any results (works fine, but items don't turn into red). If I return super.onDown (not true), the onLongPress raise every time(even I manage to release it). @Override public boolean onDown(MotionEvent e) { if(_currentRow.getTag()!=null) if(_currentRow.getTag().toString().equals("anim")) _currentRow.setBackgroundDrawable(context.getResources() .getDrawable(R.xml.listviewitem_yellow_red)); _drawable = (TransitionDrawable) _currentRow.getBackground(); _drawable.startTransition(500); return true; //super.onDown(e); // IF I UNCOMMENT IT TURNS INTO RED, BUT TRIGGERED onLongClick event!!! } @Override public boolean onSingleTapUp(MotionEvent e) { if(_drawable!=null){ _drawable.reverseTransition(500); } return super.onSingleTapUp(e); } @Override public void onLongPress(MotionEvent e) { if(getLongClickListener()!=null) getLongClickListener().onLongClick(_currentRow, _object); super.onLongPress(e); } If someone knows how to solve this problem, please help me.

  • Listening for TCP and UDP requests on the same port

    - by user339328
    I am writing a Client/Server set of programs Depending on the operation requested by the client, I use make TCP or UDP request. Implementing the client side is straight-forward, since I can easily open connection with any protocol and send the request to the server-side. On the servers-side, on the other hand, I would like to listen both for UDP and TCP connections on the same port. Moreover, I like the the server to open new thread for each connection request. I have adopted the approach explained in: link text I have extended this code sample by creating new threads for each TCP/UDP request. This works correctly if I use TCP only, but it fails when I attempt to make UDP bindings. Please give me any suggestion how can I correct this. tnx Here is the Server Code: public class Server { public static void main(String args[]) { try { int port = 4444; if (args.length > 0) port = Integer.parseInt(args[0]); SocketAddress localport = new InetSocketAddress(port); // Create and bind a tcp channel to listen for connections on. ServerSocketChannel tcpserver = ServerSocketChannel.open(); tcpserver.socket().bind(localport); // Also create and bind a DatagramChannel to listen on. DatagramChannel udpserver = DatagramChannel.open(); udpserver.socket().bind(localport); // Specify non-blocking mode for both channels, since our // Selector object will be doing the blocking for us. tcpserver.configureBlocking(false); udpserver.configureBlocking(false); // The Selector object is what allows us to block while waiting // for activity on either of the two channels. Selector selector = Selector.open(); tcpserver.register(selector, SelectionKey.OP_ACCEPT); udpserver.register(selector, SelectionKey.OP_READ); System.out.println("Server Sterted on port: " + port + "!"); //Load Map Utils.LoadMap("mapa"); System.out.println("Server map ... LOADED!"); // Now loop forever, processing client connections while(true) { try { selector.select(); Set<SelectionKey> keys = selector.selectedKeys(); // Iterate through the Set of keys. for (Iterator<SelectionKey> i = keys.iterator(); i.hasNext();) { SelectionKey key = i.next(); i.remove(); Channel c = key.channel(); if (key.isAcceptable() && c == tcpserver) { new TCPThread(tcpserver.accept().socket()).start(); } else if (key.isReadable() && c == udpserver) { new UDPThread(udpserver.socket()).start(); } } } catch (Exception e) { e.printStackTrace(); } } } catch (Exception e) { e.printStackTrace(); System.err.println(e); System.exit(1); } } } The UDPThread code: public class UDPThread extends Thread { private DatagramSocket socket = null; public UDPThread(DatagramSocket socket) { super("UDPThread"); this.socket = socket; } @Override public void run() { byte[] buffer = new byte[2048]; try { DatagramPacket packet = new DatagramPacket(buffer, buffer.length); socket.receive(packet); String inputLine = new String(buffer); String outputLine = Utils.processCommand(inputLine.trim()); DatagramPacket reply = new DatagramPacket(outputLine.getBytes(), outputLine.getBytes().length, packet.getAddress(), packet.getPort()); socket.send(reply); } catch (IOException e) { e.printStackTrace(); } socket.close(); } } I receive: Exception in thread "UDPThread" java.nio.channels.IllegalBlockingModeException at sun.nio.ch.DatagramSocketAdaptor.receive(Unknown Source) at server.UDPThread.run(UDPThread.java:25) 10x

  • Hide/Show Text Field based on Selected value - ROR

    - by Tau
    I am new to ROR. I am trying to show a "Others" text field only if the selected value is "others". I am trying to make hide/show function to be as general as possible, since I will need it in many controller. If anyone can help enlightening me, I will really appreciate it. BTW, I am using Rails 2.1.1 ruby 1.8.7 general_info.html.erb <div> <%= f.label :location_id, "Location:" %> <%= f.collection_select(:location_id, Event.locations, :id, :name, {:prompt => true}, {:onchange => remote_function( :url => {:action => "showHideDOMOther"}, :with => "'selectedText='+this.options[this.selectedIndex].text + '&other_div='+'loc_other'")}) %> </div> <div id="loc_other" style="display:none"> <%= f.label :location_others, "Others:" %> <%= f.text_field :location_others %> </div> info_controller.rb def showHideDomOther render :update do |page| page.showHideDOM("Others", params[:selectedText], params[:other_div]) end end ... application_helper.rb def showHideDOM(targetString, selectedText, targetDiv) if selectedText.casecmp targetString page.hide targetDiv else page.show targetDiv end end Seem to get the correct parameters value, but nothing seems to happen. This is what I see from the console when I changed the value of selection to "Others". Parameters: {"action"=>"showHideDOMOther", "authenticity_token"=>"e7da7ce4631480b482e29da9c0fde4c026a7a70d", "other_div"=>"loc_other", "controller"=>"events", "selectedText"=>"Others"} NoMethodError (undefined method search_generic_view_paths?' for #<EventsController:0xa41c720>): /vendor/plugins/active_scaffold/lib/extensions/generic_view_paths.rb:40:infind_template_extension_from_handler' C:/usr/lib/Ruby/lib/ruby/gems/1.8/gems/actionpack-2.1.1/lib/action_view/template_finder.rb:138:in pick_template_extension' C:/usr/lib/Ruby/lib/ruby/gems/1.8/gems/actionpack-2.1.1/lib/action_view/template_finder.rb:115:infile_exists?' : Rendering C:/usr/lib/Ruby/lib/ruby/gems/1.8/gems/actionpack-2.1.1/lib/action_controller/templates/rescues/layout.erb (internal_server_error)

  • Refreshing a JPA result list which is bound with a jTable

    - by exhuma
    First off, I hage to write this on my mobile. But I'll try to format it properly. In Netbeans I created a jTable and bound it's values to a JPA result set. This works great. The qery contains a param which i set in the pre-create box of the "query result" component. So just before netbeans creates the query result i write this: myQuery.setParameter("year", "1997"); This works fine. Now, I have an event handler which is supposed to change the param and display the new values in the table. So I do this: myQuery.setParameter("year", "2005"); myResultList.clear(); myResultList.addAll(myQuery.getResultList()); jTable1.updateUI(); This works, but it feels wrong to me. Note: the result set is bound to the table. So I was hoping there was something like this: myQuery.setParameter("year", "2005"); myResultList.refresh(); Is there something like this?
