  • Array, change color, as3

    - by pixelGreaser
    Hi Thanks for the help Yesterday, but I have on more question. How can I change color of text on certain words? My animation plays the text animation of THIS SALE IS RED HOT!!! I want RED HOT it to be red. It seems the array can be indexed in such a way to switch the color from Blue to Red. MY BANNER ADD var myArray:Array = ["THIS","SALE","IS","RED HOT!!!",]; var tm:Timer = new Timer(500); tm.addEventListener(TimerEvent.TIMER, countdown); function countdown(event:TimerEvent) { tx.text = myArray[(tm.currentCount-1)%myArray.length]; } tm.start(); tx.textColor = 0x0000FF; Cont...PSEUDO CODE //var myArray:Array = ["This","Sale","is","RED HOT!!!",]; var spliceRedhot = myArray.splice(-1); //trace(myArray[2]); trace(spliceRedhot); function mySplice(e:Event):void{ if (spliceRedhot = 4){ //Make RED HOT!!! red tx.textColor = 0xFF0000; } else{ //Text is Blue again tx.textColor = 0x0000FF; } }

  • UDP + total order, non-reliable

    - by disown
    I'm trying to find a version of UDP which just alleviates the restriction of a maximum size of the message sent. I don't care about reliability or partial retransmission, if all chunks arrive I want the message to be assembled from the chunks in sending order and delivered to the listening app. If one or more chunks are missing I would just like to discard the message. The goal is to have a low-latency notification mechanism about real time data, but with the added support for bigger messages than what would fit in an IP datagram. I would like the protocol to be one way only, and not have long connection setup times. An optional feature to be able to respond to a received message wouldn't hurt (a concept of an unreliable connection), but is not necessary.

  • MVC for a desktop application, connection a view/controller pair with another one

    - by lcf
    Hello. I've had mostly experience with "server-side" mvc frameworks very popular in different languages like ASP.NET MVC or Zend Framework for php, Spring for Java etc. Some of them are also possible to use for desktop applications development but I never tried that. I fully understand that design patterns should not limit implementation, they should generally provide ideas and common rules that can be differently implemented. Now I'm playing with one of those mvc frameworks for usual Desktop Applications development (it does not have many tutorials or a decent quickstart) and I have some questions regarding to the mvc paradigm. Here is one of them: What are common ways to link different views / controllers? If I click a button, special controller for that button dispatches the event that is generated, does something with the model, changes view state. But what if I need to interact with another view? Like, when I click on a button, it changes a model, but also I need to open another window or change state of another window (hiding a button on another window let's say...), without changing actually the model. What are common ways here to address this? Should my first controller generate an event for the second controller (or second view)? Or should the second controller be handling events from first view? Some links or examples for any languages/frameworks would be really helpful, thanks!

  • Formatting the output of a custom tool so I can double click an error in Visual Studio and the file opens

    - by Ben Scott
    I've written a command line tool that preprocesses a number of files then compiles them using CodeDom. The tool writes a copyright notice and some progress text to the standard output, then writes any errors from the compilation step using the following format: foreach (var err in results.Errors) { // err is CompilerError var filename = "Path\To\input_file.xprt"; Console.WriteLine(string.Format( "{0} ({1},{2}): {3}{4} ({5})", filename, err.Line, err.Column, err.IsWarning ? "" : "ERROR: ", err.ErrorText, err.ErrorNumber)); } It then writes the number of errors, like "14 errors". This is an example of how the error appears in the console: Path\To\input_file.xrpt (73,28): ERROR: An object reference is required for the non-static field, method, or property 'Some.Object.get' (CS0120) When I run this as a custom tool in VS2008 (by calling it in the post-build event command line of one of my project's assemblies), the errors appear nicely formatted in the Error List, with the correct text in each column. When I roll over the filename the fully qualified path pops up. The line and column are different to the source file because of the preprocessing which is fine. The only thing that stands out is that the Project given in the list is the one that has the post-build event. The problem is that when I double click an error, nothing happens. I would have expected the file to open in the editor. I'm vaugely aware of the Microsoft.VisualStudio.Shell.Interop namespace but I think it should be possible just by writing to the standard output.

  • synchronize threads - no UI

    - by UshaP
    I'm trying to write multithreading code and facing some synchronization questions. I know there are lots of posts here but I couldn't find anything that fits. I have a System.Timers.Timer that elapsed every 30 seconds it goes to the db and checks if there are any new jobs. If he finds one, he executes the job on the current thread (timer open new thread for every elapsed). While the job is running I need to notify the main thread (where the timer is) about the progress. Notes: I don't have UI so I can't do beginInvoke (or use background thread) as I usually do in winforms. I thought to implement ISynchronizeInvoke on my main class but that looks a little bit overkill (maybe I'm wrong here). I have an event in my job class and the main class register to it and I invoke the event whenever I need but I'm worrying it might cause blocking. Each job can take up to 20 minutes. I can have up to 20 jobs running concurrently. My question is: What is the right way to notify my main thread about any progress in my job thread? Thanks for any help.

  • Is it possible to disable the iPhone's automatic hyperlinks?

    - by mririgo
    We send out a notification email whenever we have "phishing" emails reported to us. In these emails, we include a copy-paste of the text inside the original phishing email as a sample of what is reported to us. Our code strips all hyperlinks out of the email via PHP, but still includes (in plain text) the link. When users receive this email in their client (Thunderbird, Outlook, Horde/IMP, etc), the hyperlink is removed. However, the iPhone likes to take web addresses in plain text and automatically turn them into hyperlinks. Is there any possible way to stop this action from happening via a HTML tag or by using PHP to replace certain parts of the hyperlink?

  • CQRS without using others patterns

    - by John Smith
    I would like to explain CQRS to my team of developers. I just can't figure out how to explain it in the simplest way so they can implement the pattern rapidly without any others frameworks. I've read a lot of resources including video and articles but I don't find how to implement CQRS without using others patterns like a service Bus, event sourcing pattern, domain driven design. I know the purpose of these pattern but for the first step, I don't want them to think CQRS and theses patterns must be tied together. My first idea is to say that CQRS is about separating the read part and the write part. The read part is composed only of the UI project, and DAL project. Then the write part is composed of a typical multilayer architecture: UI/BLL/DAL. Then, does CQRS say we must also have two datastore ? What about the notion of commands which reveal the user's intention, is it also something part of CQRS or DDD ? Basically, how to implement CQRS without using others patterns. I concede it's also not that clear in my mind because I've used to work with NCQRS/DDD/Event Sourcing/ServiceBus in my personal project. Thanks

  • Making a button click and process using javascript with Asp.Net

    - by user944919
    I'm having two buttons and one button is hidden. Now when I click the visible button I need to do two things 1.Open Iframe. 2.Automatically make the 2nd Button(Hidden)to be clicked. When the second button is clicked I need to display the message on top of the IFrame which I have mentioned as function showStickySuccessToast() Now I am able to open IFrame but I'm unable to make the Hidden button clicked automatically. This is what I'm having: <script type="text/javascript"> $(document).ready(function(){ $("#<%=Button1.ClientID%>").click(function(event){ $('#<%=TextBox1.ClientID%>').change(function () { $('#various3').attr('href', $(this).val()); }); }); function showStickySuccessToast() { $().toastmessage('showToast', { text: 'Finished Processing!', sticky: false, position: 'middle-center', type: 'success', closeText: '', close: function () { } }); } }) </script> Here are my two buttons how I'm working with: <a id="various3" href="#"><asp:Button ID="Button1" runat="server" Text="Button" OnClientClick="Button2_Click"/></a> <asp:Button ID="Button2" runat="server" Text="Button" Visible="False" OnClick="Button2_Click"/> And in the button2_Click event: Protected Sub Button2_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button2.Click System.Web.UI.ScriptManager.RegisterClientScriptBlock(Page, GetType(Page), "Script", "showStickySuccessToast();", True) End Sub

  • Shaping EF LINQ Query Results Using Multi-Table Includes

    - by sisdog
    I have a simple LINQ EF query below using the method syntax. I'm using my Include statement to join four tables: Event and Doc are the two main tables, EventDoc is a many-to-many link table, and DocUsage is a lookup table. My challenge is that I'd like to shape my results by only selecting specific columns from each of the four tables. But, the compiler is giving a compiler is giving me the following error: 'System.Data.Objects.DataClasses.EntityCollection does not contain a definition for "Doc' and no extension method 'Doc' accepting a first argument of type 'System.Data.Objects.DataClasses.EntityCollection' could be found. I'm sure this is something easy but I'm not figuring it out. I haven't been able to find an example of someone using the multi-table include but also shaping the projection. Thx,Mark var qry= context.Event .Include("EventDoc.Doc.DocUsage") .Select(n => new { n.EventDate, n.EventDoc.Doc.Filename, //<=COMPILER ERROR HERE n.EventDoc.Doc.DocUsage.Usage }) .ToList(); EventDoc ed; Doc d = ed.Doc; //<=NO COMPILER ERROR SO I KNOW MY MODEL'S CORRECT DocUsage du = d.DocUsage;

  • populate drop-down values dynamically using Ajax

    - by abhishek
    Hi, I have 3 drop-downs. 1st drop-down contains some values when the page loads. I need to populate 2 nd drop-down based on the value selected in 1st dropdown. Similarly, I need to populate 3 nd drop-down based on the value selected in 1st and 2nd dropdown. Initially I tried like this. <h:selectOneMenu value="#{stu.country}" > <f:selectItems value="#{bean.allCountries}" /> <a4j:support event="onchange" action="#{bean.retrieveStates(stu.country)}" reRender="states_dropDown"></a4j:support> </h:selectOneMenu> //ly, for 2nd drop-down <h:selectOneMenu id="states_dropDown" value="#{stu.state}" > <f:selectItems value="#{bean.allStates}" /> <a4j:support event="onchange" action="#{bean.retrieveCities(stu.country,stu.state)}" reRender="City_dropDown"></a4j:support> </h:selectOneMenu> Some times this code works fine. But some times it doesn't invoke managed bean method. Can you please help??

  • Using complex where clause in NHibernate mapping layer

    - by JLevett
    I've used where clauses previously in the mapping layer to prevent certain records from ever getting into my application at the lowest level possible. (Mainly to prevent having to re-write lots of lines of code to filter out the unwanted records) These have been simple, one column queries, like so this.Where("Invisible = 0"); However a scenario has appeared which requires the use of an exists sql query. exists (select ep_.Id from [Warehouse].[dbo].EventPart ep_ where Id = ep_.EventId and ep_.DataType = 4 In the above case I would usually reference the parent table Event with a short name, i.e. event_.Id however as Nhibernate generates these short names dynamically it's impossible to know what it's going to be. So instead I tried using just Id, from above ep_ where Id = ep_.EventId When the code is run, because of the dynamic short names the EventPart table short name ep_ is has another short name prefixed to it, event0_.ep_ where event0_ refers to the parent table. This causes an SQL error because of the . in between event0_ and ep_ So in my EventMap I have the following this.Where("(exists (select ep_.Id from [isnapshot.Warehouse].[dbo].EventPart ep_ where Id = ep_.EventId and ep_.DataType = 4)"); but when it's generated it creates this select cast(count(*) as INT) as col_0_0_ from [isnapshot.Warehouse].[dbo].Event event0_ where (exists (select ep_.Id from [isnapshot.Warehouse].[dbo].EventPart event0_.ep_ where event0_.Id = ep_.EventId and ep_.DataType = 4) It has correctly added the event0_ to the Id Was the mapping layer where clause built to handle this and if so where am I going wrong?

  • Return a Const Char* by reading an @property NSString in separate class

    - by Andrew
    I'm probably being an idiot here, but I cannot for the life of me find the answer that I'm looking for. I have an array of CalEvents returned from a CalendarStore query, and for other reasons I am finding the first location of any upcoming event for today that is not an all-day or multi-day event. +(const char*) suggestFirstiCalLocation{ CalCalendarStore *store = [CalCalendarStore defaultCalendarStore]; NSPredicate *allEventsPredicate = [CalCalendarStore eventPredicateWithStartDate:[NSDate date] endDate:[[NSDate date] initWithTimeIntervalSinceNow:3600] calendars:[store calendars]]; NSArray *currentEventCalendarArray = [store eventsWithPredicate:allEventsPredicate]; for (int i = 0; i< [currentEventCalendarArray count]; i++){ if (![[currentEventCalendarArray objectAtIndex:i] isAllDay]){ //Now that other events are cleared, check for multi-day NSDate *startOnDate = [[currentEventCalendarArray objectAtIndex:i] startDate]; NSDate *endOnDate = [[currentEventCalendarArray objectAtIndex:i] endDate]; if ([endOnDate timeIntervalSinceDate:startOnDate ] < 86400.0){ NSString * iCalLocation = [[currentEventCalendarArray objectAtIndex:i] location]; return [iCalLocation UTF8String]; } } } return ""; } For other reasons, I am returning a const char with the value of the location that is found. However, I cannot seem to return "iCalLocation" at all. The compiler fails on the line where I am initializing the "iCalLocation" variable: "Cannot convert to pointer type" Being frank: I am new to Objective-C, and I am still trying to figure points, properties, and such out.

  • Irregular layout ItemsControl

    - by firoso
    I have a strange layout for an ItemsControl. I have a 4x6 grid with the following pattern: 1 2 3 4 13 14 15 16 5 6 7 8 17 18 19 20 9 10 11 12 21 22 23 24 Is there an easy way to do this? should I be using 6 Items Controls and take "sections" of my list? is there a good way to do this? What about notification? It's important to note that I may, or may not, have all 24 entries present, but the layout needs to be maintained (think of it like filled slots on a bingo card or something)

  • jquery tabbed interface breaks when using images

    - by Steve
    hello all, using jquery to create a tabbed interface. coding is quite typical: html: <div id="tabbed-interface"> <ul> <li><a href="#option1">Option1</a></li> <li><a href="#option2">Option2</a></li> <li><a href="#option3">Option3</a></li> </ul> </div> jquery: $(document).ready(function(){ $('#tabbed-interface li:first').addClass('active'); $('#tabbed-interface div').not(':first').hide(); $('#tabbed-interface>ul>li>a').click(function(event){ $('#tabbed-interface>ul>li').removeClass('active'); $(event.target).parent().addClass('active'); $('#tabbed-interface>div').fadeOut().filter(this.hash).fadeIn(250); return false;});}); css: ul li {background: #232323; list-style: none; border: 1px solid #616161; } ul li.active {background: none; list-style: none; border: 1px solid: #616161; border-bottom: 1px solid #121212; z-index: 1; } as you can see, all this does is add the class 'active' to the li that is clicked, and this corresponds to whether a background is shown or not. this works perfectly with text, but i am required to use non standard fonts. when i try to side step the issue using transparent .png images, it is unreliable. For instance, changing the HTML to: <div id="tabbed-interface"> <ul> <li><a href="#option1"><img src="option1.png" /></a></li>

  • C++ MFC server app with sockets crashes and I cannot find the fault, help!

    - by usermeister
    My program has one dialog and two sockets. Both sockets are derived from CAsyncSocket, one is for listening, other is for receiving data from client. My program crashes when client tries to connect to server application and server needs to initialize receiving socket. This is my MFC dialog class. class CFileTransferServerDlg : public CDialog { ... ListeningSocket ListenSock; ReceivingSocket* RecvSock; void OnAccept(); // called when ListenSock gets connection attempt ... }; This is my derived socket class for receiving data that calls parent dialogs method when event is signaled. class ReceivingSocket : public CAsyncSocket { CFileTransferServerDlg* m_pDlg; // for accessing parent dialogs controls virtual void OnReceive(int nErrorCode); } ReceivingSocket::ReceivingSocket() { } This is dialogs function that handles incoming connection attempt when listening socket gets event notification. This is where the crash happens. void CFileTransferServerDlg::OnAccept() { RecvSock = new ReceivingSocket; /* CRASH */ } OR void CFileTransferServerDlg::OnAccept() { ReceivingSocket* tmpSock = new ReceivingSocket; tmpSock->SetParentDlg(this); CString message; if( ListenSock.Accept(*tmpSock) ) /* CRASH */ { message.LoadStringW(IDS_CLIENT_CONNECTED); m_txtStatus.SetWindowTextW(message); RecvSock = tmpSock; } } My program crashes when I try to create a socket for receiving file sent from client application. OnAccept starts when Listening socket signals incoming connection attempt, but my application then crashes. I've tried running it on another computer and connection attempt was succesful. What could be wrong? Error in debug mode: Unhandled exception at 0x009c30e1 in FileTransferServer.exe: 0xC0000005: Access violation reading location 0xccccce58.

  • why Observable snapshot observer vector

    - by han14466
    In Observable's notifyObservers method, why does the coder use arrLocal = obs.toArray();? Why does not coder iterate vector directly? Thanks public void notifyObservers(Object arg) { Object[] arrLocal; synchronized (this) { /* We don't want the Observer doing callbacks into * arbitrary code while holding its own Monitor. * The code where we extract each Observable from * the Vector and store the state of the Observer * needs synchronization, but notifying observers * does not (should not).

  • Magento: How do I get observers to work in an external script?

    - by Laizer
    As far as I can tell, when a script is run outside of Magento, observers are not invoked when an event is fired. Why? How do I fix it? Below is the original issue that lead me to this question. The issue is that the observer that would apply the catalog rule is never called. The event fires, but the observer doesn't pick it up. I'm running an external script that loads up a Magento session. Within that script, I'm loading products and grabbing a bunch of properties. The one issue is that getFinalPrice() does not apply the catalog rules that apply to the product. I'm doing everything I know to set the session, even a bunch of stuff that I think is superfluous. Nothing seems to get these rules applied. Here's a test script: require_once "app/Mage.php"; umask(0); $app = Mage::app("default"); $app->getTranslator()->init('frontend'); //Probably not needed Mage::getSingleton('core/session', array('name'=>'frontend')); $session = Mage::getSingleton("customer/session"); $session->start(); //Probably not needed $session->loginById(122); $product = Mage::getModel('catalog/product')->load(1429); echo $product->getFinalPrice(); Any insight is appreciated.

  • Sharing state/changes across ViewModels

    - by joshperry
    I have an App which has a Tasks tab and a Projects tab. I decided to make a separate ViewModel for each of the tabs, TasksViewModel and ProjectsViewModel. The Tasks tab has a new task area with an associated project pulldown and the Projects tab (obviously) has a list of projects. What I'd like is for the pulldown on the Tasks tab to share the same collection as the Projects tab list so that any time I add or remove a project on the Projects tab the list on the Tasks tab is up to date automatically. This worked well with a single ViewModel but it was beginning to become quite unruly. Should I not have split into two ViewModels? Is there a common method of sharing data like this? Perhaps pass the same ObservableCollection<Project> into each of the ViewModels? Perhaps some type of notification back to the TasksViewModel along the lines of ICollectionChanged. Appreciate any insight/input!

  • Firefox extension dev: observing preferencies, avoid multiple notifications

    - by Michael
    Let's say my Firefox extension has multiple preferences, but some of them are grouped, like check interval, fail retry interval, destination url. Those are used in just single function. When I subscribe to preference service and add observer, the observe callback will be called for each changed preference, so if by chance user changed all of the settings in group, then I will have to do the same routine for the same subsystem as many times as I have items in that preferences group. What I want is observe to be called just once for group of preferences. Say extensions.myextension.interval1 extensions.myextension.site extensions.myextension.retry so if one or all of those preferences are changed, I receive only 1 notification about it.

  • How can I bind multiple Jquery UI Slider with "year" Select?

    - by arthur_br
    Hi, I'm trying to render sliders instead of select components. Each page has several select components marked with class='jqselect' and all of them will have decreasing year values (some years may be missing). Eg. a select may have values [2010, 2009, 2006, 2005, 2004]. I have tried binding it both following the examples in the jQuery UI doc (but ignoring the missing years) and using selectToUISlider by filamentgroup (http://www.filamentgroup.com/lab/update_jquery_ui_slider_from_a_select_element_now_with_aria_support//). None of them work. Here is what I've done so far: Binding selects with following slider container divs: $('#content div.jqslider').slider({ animate: true, min: $(this).prev().children().last().val(), max: $(this).prev().children().first().val(), slide: function(event, ui) { var select = $(this).prev(); select.val($(this).slider('option', 'value')); console.log($(this).slider('option', 'value')); //debug } }); This renders the slider, but console logs values from 0 to 100 and selects obviously does not change with the event. Using selectToUISlider: $('#content select.jqselect').selectToUISlider(); This does not even render the slider, throwing an error 'b is undefined' in jquery-min.js (line 30, v1.4.2). If I pass the identifier of only one of the sliders, it is rendered but very buggy. Please, I'm stucked in the by two days and any help is much appreciated. Regards, Arthur

  • Secure messaging using Signed MIME is it reliable?

    - by aaronb
    We have an automatic reporting and notification system written in .net that sends emails with plain text. We are having to encrypt the messages that we send our clients. The possible implementation approaches we have: Send messages as S/Mime email with attachments. Plain text email with that just contains a link to a web site that will display the message over https. It seems like S/Mime is a simpler solution, as we won't need to create the web application or secure it. Our concern is our interoperability with our clients email clients and more importantly their email filtering software. Has anyone had success or issues deploying a Signed MIME messaging solution?

  • How do you hide a Swing Popup when you click somewhere else.

    - by Casey Watson
    I have a Popup that is shown when a user clicks on a button. I would like to hide the popup when any of the following events occur: The user clicks somewhere else in the application. (The background panel for example) The user minimizes the application. The JPopupMenu has this behavior, but I need more than just JMenuItems. The following code block is a simplified illustration to demonstrate the current usage. import java.awt.*; import java.awt.event.ActionEvent; import javax.swing.*; public class PopupTester extends JFrame { public static void main(String[] args) { final PopupTester popupTester = new PopupTester(); popupTester.setLayout(new FlowLayout()); popupTester.setSize(300, 100); popupTester.add(new JButton("Click Me") { @Override protected void fireActionPerformed(ActionEvent event) { Point location = getLocationOnScreen(); int y = (int) (location.getY() + getHeight()); int x = (int) location.getX(); JLabel myComponent = new JLabel("Howdy"); Popup popup = PopupFactory.getSharedInstance().getPopup(popupTester, myComponent, x, y); popup.show(); } }); popupTester.add(new JButton("No Click Me")); popupTester.setVisible(true); popupTester.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); } }

  • WinForms: How to determine if window is no longer active (no child window has focus)?

    - by Marek
    My application uses multiple windows I want to hide one specific window in case the application loses focus (when the Active Window is not the application window) source I am handling the Deactivate event of my main form. private void MainForm_Deactivate(object sender, EventArgs e) { Console.WriteLine("deactivate"); if (GetActiveWindow() == this.Handle) { Console.WriteLine("isactive=true"); } else { Console.WriteLine("isactive=false"); } } [DllImport("user32.dll")] static extern IntPtr GetActiveWindow(); The output is always deactivate isactive=true I have observed the same behavior if a new window within my application receives focus and also if I click into a different application. I would expect GetActiveWindow to return the handle of the new active window when called from the Deactivate handler. Instead it always returns the handle of my application window. How is this possible? Is the Deactivate event handled "too soon"? (while the main form is still active?). How can I detect that my application has lost focus (my application window is not the active window) and another application gained it without running GetActiveWindow on a timer?

  • In ActionScript, is there a way to test for existence of variable with datatype "Function"

    - by Robusto
    So I have a class where I instantiate a variable callback like so: public var callback:Function; So far so good. Now, I want to add an event listener to this class and test for existence of the callback. I'm doing like so: this.addEventListener(MouseEvent.MOUSE_OVER, function(event:MouseEvent) : void { if (callback) { // do some things } }); This works great, doesn't throw any errors, but everywhere I test for callback I get the following warning: 3553: Function value used where type Boolean was expected. Possibly the parentheses () are missing after this function reference. That bugged me, so I tried to get rid of the warning by testing for null and undefined. Those caused errors. I can't instantiate a Function as null, either. I know, I know, real programmers only care about errors, not warnings. I will survive if this situation is not resolved. But it bothers me! :) Am I just being neurotic, or is there actually some way to test whether a real Function has been created without the IDE bitching about it?
