  • spring.net proxy factory with target type needs property virtual ?

    - by Vince
    Hi all, I'm creating spring.net proxy in code by using ProxyFactory object with ProxyTargetType to true to have a proxy on a non interfaced complex object. Proxying seems ok till i call a method on that object. The method references a public property and if this property is not virtual it's value is null. This doesn't happen if i use Spring.Aop.Framework.AutoProxy.InheritanceBasedAopConfigurer in spring config file but in this case i can't use this because spring context doesn't own this object. Is this normal to have such behavior or is there a tweak to perform what i want (proxying object virtual method without having to change properties virtual)? Note that i tried factory.AutoDetectInterfaces and factory.ProxyTargetAttributes values but doesn't help. My proxy creation code: public static T CreateMethodCallStatProxy<T>() { // Proxy factory ProxyFactory factory = new ProxyFactory(); factory.AddAdvice(new CallMonitorTrackerAdvice()); factory.ProxyTargetType = true; // Create instance factory.Target = Activator.CreateInstance<T>(); // Get proxy T proxiedClass = (T)factory.GetProxy(); return proxiedClass; } Thanks for your help

  • Timer Service in ejb 3.1 - schedule calling timeout problem

    - by Greg
    Hi Guys, I have created simple example with @Singleton, @Schedule and @Timeout annotations to try if they would solve my problem. The scenario is this: EJB calls 'check' function every 5 secconds, and if certain conditions are met it will create single action timer that would invoke some long running process in asynchronous fashion. (it's sort of queue implementation type of thing). It then continues to check, but as long as long running process is there it won't start another one. Below is the code I came up with, but this solution does not work, because it looks like asynchronous call I'm making is in fact blocking my @Schedule method. @Singleton @Startup public class GenerationQueue { private Logger logger = Logger.getLogger(GenerationQueue.class.getName()); private List<String> queue = new ArrayList<String>(); private boolean available = true; @Resource TimerService timerService; @Schedule(persistent=true, minute="*", second="*/5", hour="*") public void checkQueueState() { logger.log(Level.INFO,"Queue state check: "+available+" size: "+queue.size()+", "+new Date()); if (available) { timerService.createSingleActionTimer(new Date(), new TimerConfig(null, false)); } } @Timeout private void generateReport(Timer timer) { logger.info("!!--timeout invoked here "+new Date()); available = false; try { Thread.sleep(1000*60*2); // something that lasts for a bit } catch (Exception e) {} available = true; logger.info("New report generation complete"); } What am I missing here or should I try different aproach? Any ideas most welcome :) Testing with Glassfish 3.0.1 latest build - forgot to mention

  • Browsers disagree about the text of a body element

    - by Charles Anderson
    My HTML looks like this: <html> <head> <title>Test</title> <script type="text/javascript" src="jQuery.js"></script> <script type="text/javascript"> function init() { var text = jQuery('body').text(); alert('length = ' + text.length); } </script> </head> <body onload="init()">0123456789</body> </html> When I load this in Firefox, the length is reported as 10. However, in Chrome it's 11 because it thinks there's a linefeed after the '9'. In IE it's also 11, but the last character is an escape. Meanwhile, Opera thinks there are 12 characters, with the last two being CR LF. If I change the body element to include a span: <body onload="init()"><span>0123456789</span></body> and the jQuery call to: var text = jQuery('body span').text(); then all the browsers agree that the length is 10. Clearly it's the body element that's causing the issue, but can anyone explain exactly why this is happening? I'm particularly surprised because the excellent jQuery is normally browser-independent.

  • Using SetParent to steal the main window of another process but keeping the message loops separate

    - by insta
    Background: My coworker and I are maintaining a million-line legacy application we inherited. Its frontend is written in VB6, and as we're devoting almost all of our resources to converting it to C#, we are looking for quick & dirty solutions to our specific problem. The application behaves in a plugin-ish manner. There are up to 20ish separate ActiveX controls that can be loaded at once in a grid-style layout. The problem is that the ActiveX controls do all of their processing on their own UI thread, and as a lot of it is blocking waiting on network access, the UI gets very soupy. When our hosting C# app loads these controls, it becomes unresponsive because of how many controls are chewing up UI resources doing nothing. To top it off, the controls are fragile and will crash at the slightest provocation. When they are hosted in the main C# app, it creates serious instability. The best my coworker and I have come up with so far is starting a process per ActiveX control. This process, which we call the proxy, is another winforms app. It uses named pipes to communicate with the hosting process. The hosting process creates a window, loads an ActiveX control of our choice (via some reflections & AxHost magic), and tells the main process what its window handle is via the named pipe. The main process uses a combination of SetParent, and SetWindowPos to move the proxy application into itself to emulate a plugin. Size updates are sent via the named pipe. This works well enough until the ActiveX application does some sort of lengthy process and we click around on the main window while it's working. For awhile the main window is responsive, but eventually it becomes unresponsive as the child window waits for its UI thread. How can we keep the child windows on their own complete thread while still getting the benefits of SetParent? (please let me know if anything isn't clear!)

  • Pointer initialization

    - by SoulBeaver
    Sorry if this question has been asked before. On my search through SO I didn't find one that asked what I wanted to know. Basically, when I have this: typedef struct node { int data; node *node; } *head; and do node *newItem = new node; I am under the impression that I am declaring and reserving space, but not defining, a pointer to struct node, is that correct? So when I do newItem->data = 100 and newItem->next = 0 I get confused. newItem = 0would declare what exactly? Both data and next? The object as a whole? I'm especially confused when I use typedef. Which part is the macro? I assume node because that's how I call it, but why do I need it? Finally, what happens when I do: node *temp; temp = new node; temp = head->next; head->next = newItem; newItem->next = temp; I mean, head-next is a pointer pointing to object newItem, so I assume not to newItem.data or next themselves. So how can I use an uninitialized pointer that I described above safely like here? is head now not pointing to an uninitialized pointer?

  • Canceling a WSK I/O operation when driver is unloading

    - by eaducac
    I've been learning how to write drivers with the Windows DDK recently. After creating a few test drivers experimenting with system threads and synchronization, I decided to step it up a notch and write a driver that actually does something, albeit something useless. Currently, my driver connects to my other computer using Winsock Kernel and just loops and echoes back whatever I send to it until it gets the command "exit", which causes it to break out of the loop. In my loop, after I call WskReceive() to get some data from the other computer, I use KeWaitForMultipleObjects() to wait for either of two SynchronizationEvents. BlockEvent gets set by my IRP's CompletionRoutine() to let my thread know that it's received some data from the socket. EndEvent gets set by my DriverUnload() routine to tell the thread that it's being unloaded and it needs to terminate. When I send the "exit" command, the thread terminates with no problems, and I can safely unload the driver afterward. If I try to stop the driver while it's still waiting on data from the other computer, however, it blue screens with the error DRIVER_UNLOADED_WITHOUT_CANCELLING_PENDING_OPERATIONS. After I get the EndEvent but before I exit the loop, I've tried canceling the IRP with IoCancelIrp() and completing it with IoCompleteRequest(), but both of those give me DRIVER_IRQL_NOT_LESS_OR_EQUAL errors. I then tried calling WskDisconnect(), hoping that would cause the receive operation to complete, but that took me back to the CANCELLING_PENDING_OPERATIONS error. How do I cancel my pending I/O operation from my WSK socket at the IRQL I'm running at when the driver is unloaded?

  • Multiple queries using same datacontext throws SqlException

    - by Raj
    I've search control with which I'm trying to implement search as user types something. I'm using Linq to SQL to fire queries against the database. Though it works fine usually, when user types the queries really fast some random SqlException is thrown.

  • Automated testing for Facebook SDK wrapper

    - by Andree
    Hi there! In my Facebook application, I have one Facebook wrapper class to encapsulates some call to Facebook API. I want to to write a unit test for this wrapper class, but since it depends on a so called "access token", which we should get from Facebook dynamically, I'm not sure if it's possible to write one. But apparently the Facebook SDK itself has a PHPUnit test class. After studying the test code for a while, I know that involves a creation of dummy cookie-based session key. private static $VALID_EXPIRED_SESSION = array( 'access_token' => '254752073152|2.I_eTFkcTKSzX5no3jI4r1Q__.3600.1273359600-1677846385|uI7GwrmBUed8seZZ05JbdzGFUpk.', 'expires' => '1273359600', 'secret' => '0d9F7pxWjM_QakY_51VZqw__', 'session_key' => '2.I_eTFkcTKSzX5no3jI4r1Q__.3600.1273359600-1677846385', 'sig' => '9f6ae89510b30dddb3f864f3caf32fb3', 'uid' => '1677846385' ); . . . $cookieName = 'fbs_' . self::APP_ID; $session = self::$VALID_EXPIRED_SESSION; $_COOKIE[$cookieName] = '"' . http_build_query($session) . '"'; What I don't understand is, how do I get the "access_token", "sig", "session_key" etc? As far as I'm concerned, it should be dynamically exchanged from Facebook and involves user action (logging in).

  • ASP.NET Response Filter to Reformat the rendered output of ASPX pages?

    - by PropellerHead
    I've created a simple HttpModule and response stream to reformat the rendered output of web pages (see code snippets below). In the HttpModule I set the Response.Filter to my PageStream: m_Application.Context.Response.Filter = new PageStream(m_Application.Context); In the PageStream I overwrite the Write method in order to do my reformatting of the rendered output: public override void Write(byte[] buffer, int offset, int count) { string html = System.Text.Encoding.UTF8.GetString(buffer); //Do some string resplace operations here... byte[] input = System.Text.Encoding.UTF8.GetBytes(html); m_DefaultStream.Write(input, 0, input.Length); } And this work fine when using it on simple HTML pages (.html), but when I use this method on ASPX pages (.aspx), the Write method is called several times, splitting up the reformatting into different steps, and potentially destroying the string replacement operations. How do I solve this? Is there a way to let the ASPX page NOT call Write several times, e.g. by changing its buffer size, or have I chosen the wrong approach entirely, by using this Response.Filter method to manipulate the rendered output?

  • Can I delay the keyup event for jquery?

    - by Paul
    I'm using the rottentomatoes movie API in conjunction with twitter's typeahead plugin using bootstrap 2.0. I've been able to integerate the API but the issue I'm having is that after every keyup event the API gets called. This is all fine and dandy but I would rather make the call after a small pause allowing the user to type in several characters first. Here is my current code that calls the API after a keyup event: var autocomplete = $('#searchinput').typeahead() .on('keyup', function(ev){ ev.stopPropagation(); ev.preventDefault(); //filter out up/down, tab, enter, and escape keys if( $.inArray(ev.keyCode,[40,38,9,13,27]) === -1 ){ var self = $(this); //set typeahead source to empty self.data('typeahead').source = []; //active used so we aren't triggering duplicate keyup events if( !self.data('active') && self.val().length > 0){ self.data('active', true); //Do data request. Insert your own API logic here. $.getJSON("http://api.rottentomatoes.com/api/public/v1.0/movies.json?callback=?&apikey=MY_API_KEY&page_limit=5",{ q: encodeURI($(this).val()) }, function(data) { //set this to true when your callback executes self.data('active',true); //Filter out your own parameters. Populate them into an array, since this is what typeahead's source requires var arr = [], i=0; var movies = data.movies; $.each(movies, function(index, movie) { arr[i] = movie.title i++; }); //set your results into the typehead's source self.data('typeahead').source = arr; //trigger keyup on the typeahead to make it search self.trigger('keyup'); //All done, set to false to prepare for the next remote query. self.data('active', false); }); } } }); Is it possible to set a small delay and avoid calling the API after every keyup?

  • CALayer and Off-Screen Rendering

    - by Luke Mcneice
    I have a Paging UIScrollView with a contentSize large enough to hold a number of small UIScrollViews for zooming, The viewForZoomingInScrollView is a viewController that holds a CALayer for drawing a PDF page onto. This allows me to navigate through a PDF much like the ibooks PDF reader. The code that draws the PDF (Tiled Layers) is located in: - (void)drawLayer:(CALayer *)layer inContext:(CGContextRef)ctx; And simply adding a 'page' to the visible screen calls this method automatically. When I change page there is some delay before all the tiles are drawn, even though the object (page) has already been created. What i want to be able to do is render the next page before the user scrolls to it, thus preventing the visible tiling effect. However, i have found that if the layer is located offscreen adding it to the scrollview doesn't call the drawLayer. Any Ideas/common gotchas here? I have tried: [viewController.view.layer setNeedsLayout]; [viewController.view.layer setNeedsDisplay]; NB: The fact that this is replicating the ibooks functionally is irrelevant within the context of the full app.

  • I can't find the cause of an "unchecked or unsafe operations" warning in Java.

    - by Peter
    Hello, as per the title I am struggling to find the cause of an "unchecked or unsafe operations" warning in some code. If I have the following code, it compiles without any warnings: public void test() { Set<String> mySet = new HashSet<String>(); Set<String> myNewSet = mySet; //do stuff } Now, if I change where mySet comes from, specifically as the result of a method call, I get the "unchecked yadda yadda" warning: public void test() { Set<String> myNewSet = this.getSet(); //do stuff } public Set getSet() { Set<String> set = new HashSet<String>(); return set; } I have tried and tried to work out what the problem is and I am completely stumped. The issue is present whether I use Sets or Lists. Why would the Set returned by the getSet method be any different to the Set in the first example? Any help would be greatly appreciated as while the warning isn't the end of the world, it is bugging the hell out of me! :( Regards

  • Problem with setVisible (true)

    - by Jessy
    The two examples shown below are same. Both are supposed to produce same result e.g. generate the coordinates of images displayed on JPanel. Example 1, works perfectly (print the coordinates of images), however example 2 returning 0 for the coordinate. I was wondering why because, I have put the setvisible (true) after adding the panel, in both examples. The only difference is that example 1 used extends JPanel and example 2 extends JFrame EXAMPLE 1: public class Grid extends JPanel{ public static void main(String[] args){ JFrame jf=new JFrame(); jf.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); final Grid grid = new Grid(); jf.add(grid); jf.pack(); Component[] components = grid.getComponents(); for (Component component : components) { System.out.println("Coordinate: "+ component.getBounds()); } jf.setVisible(true); } } EXAMPLE 2: public class Grid extends JFrame { public Grid () { setLayout(new GridBagLayout()); GridBagLayout m = new GridBagLayout(); Container c = getContentPane(); c.setLayout (m); GridBagConstraints con = new GridBagConstraints(); //construct the JPanel pDraw = new JPanel(); ... m.setConstraints(pDraw, con); pDraw.add (new GetCoordinate ()); // call new class to generate the coordinate c.add(pDraw); pack(); setVisible(true); } public static void main(String[] args) { new Grid(); } }

  • Verify an event was raised by mocked object

    - by joblot
    In my unit test how can I verify that an event is raised by the mocked object. I have a View(UI) -- ViewModel -- DataProvider -- ServiceProxy. ServiceProxy makes async call to serivce operation. When async operation is complete a method on DataProvider is called (callback method is passed as a method parameter). The callback method then raise and event which ViewModel is listening to. For ViewModel test I mock DataProvider and verify that handler exists for event raised by DataProvider. When testing DataProvider I mock ServiceProxy, but how can I test that callback method is called and event is raised. I am using RhinoMock 3.5 and AAA syntax Thanks -- DataProvider -- public partial class DataProvider { public event EventHandler<EntityEventArgs<ProductDefinition>> GetProductDefinitionCompleted; public void GetProductDefinition() { var service = IoC.Resolve<IServiceProxy>(); service.GetProductDefinitionAsync(GetProductDefinitionAsyncCallback); } private void GetProductDefinitionAsyncCallback(ProductDefinition productDefinition, ServiceError error) { OnGetProductDefinitionCompleted(this, new EntityEventArgs<ProductDefinition>(productDefinition, error)); } protected void OnGetProductDefinitionCompleted(object sender, EntityEventArgs<ProductDefinition> e) { if (GetProductDefinitionCompleted != null) GetProductDefinitionCompleted(sender, e); } } -- ServiceProxy -- public class ServiceProxy : ClientBase<IService>, IServiceProxy { public void GetProductDefinitionAsync(Action<ProductDefinition, ServiceError> callback) { Channel.BeginGetProductDefinition(EndGetProductDefinition, callback); } private void EndGetProductDefinition(IAsyncResult result) { Action<ProductDefinition, ServiceError> callback = result.AsyncState as Action<ProductDefinition, ServiceError>; ServiceError error; ProductDefinition results = Channel.EndGetProductDefinition(out error, result); if (callback != null) callback(results, error); } }

  • qtruby, QUiLoader and respond_to?

    - by Tim Sylvester
    I'm writing a simple Qt4 application in Ruby (using qtruby) to teach myself both. Mostly it has gone well, but in trying to use Ruby's "duck typing" I've run into a snag; respond_to? doesn't seem to reflect reality. irb(main):001:0> require 'rubygems' => true irb(main):002:0> require 'Qt4' => true irb(main):003:0> require 'qtuitools' => true irb(main):004:0> Qt::Application.new(ARGV) => #<Qt::Application:0xc3c9a08 objectName="ruby"> irb(main):005:0> file = Qt::File.new("dlg.ui") { open(Qt::File::ReadOnly) } => #<Qt::File:0xc2e1748 objectName=""> irb(main):006:0> obj = Qt::UiLoader.new().load(file, nil) => #<Qt::Dialog:0xc2bf650 objectName="dlg", x=0, y=0, width=283, height=244> irb(main):007:0> obj.respond_to?('children') => false irb(main):008:0> obj.respond_to?(:children) => false irb(main):009:0> obj.children => [#<Qt::FormInternal::TranslationWatcher:0xc2a1980 objectName="">, ... As you can see, when I check to ensure that the object I get back from loading the UI file has a children accessor I get false. If call that accessor, however, I get an array rather than a NoMethodError. So, is this a bug or have I incorrectly understood respond_to?? This looks like the problem described here, but I thought I would get an expert opinion before filing a bug against the project.

  • how to play an audio soundclip when a nib is loaded - welcome screen - xcode

    - by Pavan
    I would like to do the following two things: 1) I would like to play an audio file qhen a nib is loaded 2) After that i would like to switch views when the audio file has finished playing. This will be easy as i just need to call the event that initiates the change of view by using the delegate method -(void) audioPlayerDidFinishPlaying{ //code to change view } I dont know how to to play the audio file when a nib is loaded. Using the AVFoundation framework, I tried doing the following after setting up the audio player and the variables associated with it in the appropriate places i wrote the following: - (void)viewDidLoad { [super viewDidLoad]; NSString *soundFilePath = [[NSBundle mainBundle] pathForResource: @"sound" ofType: @"mp3"]; NSURL *fileURL = [[NSURL alloc] initFileURLWithPath: soundFilePath]; AVAudioPlayer *newPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL: fileURL error:nil]; [fileURL release]; self.player = newPlayer; [newPlayer release]; [player prepareToPlay]; [player setDelegate: self]; [player play]; } Although this does not play the file as the viewdidload method gets called before the nib is shown so the audio is never played or heard. What do i need to do so that i can play the audio file AFTER the nib has loaded and is shown on the screen? can someone please help me as ive been working on this for 3 hours now. Thanks in advance.

  • Old fashioned html onclick return false doesnt in IE work when jquery script included

    - by user292662
    Ok, so im quite new to jquery but found this bizzar problem just now, If we ignore jquery for a second and consider this scenario, if i have two links like below both with an href and both with and onclick event. The first link will not follow the href because the onclick returns false, and the second link will because the onclick returns true. <a href="/page.html" onclick="return false;">Dont follow</a> <a href="/page.html" onclick="return false;">Follow</a> This works just hunky dory in every browser as it should, the thing is, as soon as i include the jQuery script on the page this stops working in all versions of IE which then always follows the href whether the onclick returns false or not. (it continues to work fine in other browsers) Now if i add an event using jquery and call .preventDefault() on the event object instead of doing it the old fashioned way this behaves correctly, and you may say, well just do that then? But i have a site with thousands of lines of code and i am adding jquery support, i dont want to run the risk that i might miss an already defined html onclick="" and break the website. I cant see why jQuery should prevent perfectly normal javascript concepts from working, so is this a jQuery bug or am I missing something?

  • OpenMP - running things in parallel and some in sequence within them

    - by Sayan Ghosh
    Hi, I have a scenario like: for (i = 0; i < n; i++) { for (j = 0; j < m; j++) { for (k = 0; k < x; k++) { val = 2*i + j + 4*k if (val != 0) { for(t = 0; t < l; t++) { someFunction((i + t) + someFunction(j + t) + k*t) } } } } } Considering this is block A, Now I have two more similar blocks in my code. I want to put them in parallel, so I used OpenMP pragmas. However I am not able to parallelize it, because I am a tad confused that which variables would be shared and private in this case. If the function call in the inner loop was an operation like sum += x, then I could have added a reduction clause. In general, how would one approach parallelizing a code using OpenMP, when we there is a nested for loop, and then another inner for loop doing the main operation. I tried declaring a parallel region, and then simply putting pragma fors before the blocks, but definitely I am missing a point there! Thanks, Sayan

  • PHP File Upload, using the FILES superglobal array

    - by jnkrois
    Hello everybody, I just have a quick question. Let's say that I'm setting up an upload feature for a project. I'm using PHP5, and I was wondering if by using the $_FILES superglobal array, I could have access to the "tmp_name" array key , which is the temporary path and name of the file being uploaded to display a preview of the image, before moving it to the "uploads" folder in the server. What I had in mind is something like this: Use jQuery to detect when the "file" input filed changes (when the user selects an image file), then place an ajax call to upload the the file, which will move it to the temp folder even before I use "move_uploaded_file". If I can somehow access the "tmp_name" array key, I could probably put it into and "img" tag to display a preview. Later move the file to it's final location when the submit button is clicked. I'm not asking for any code examples or anything, since I'd be thrilled to accomplish this on my own, I just want to find out if there is access to that array key in any way. Thanks in advance.

  • Is it possible to unit test methods that rely on NHibernate Detached Criteria?

    I have tried to use Moq to unit test a method on a repository that uses the DetachedCriteria class.

Any help would be gratefully appreciated.

  • How do I get save (no exclamation point) semantics in an ActiveRecord transaction?

    - by James A. Rosen
    I have two models: Person and Address which I'd like to create in a transaction. That is, I want to try to create the Person and, if that succeeds, create the related Address. I would like to use save semantics (return true or false) rather than save! semantics (raise an ActiveRecord::StatementInvalid or not). This doesn't work because the user.save doesn't trigger a rollback on the transaction: class Person def save_with_address(address_options = {}) transaction do self.save address = Address.build(address_options) address.person = self address.save end end end (Changing the self.save call to an if self.save block around the rest doesn't help, because the Person save still succeeds even when the Address one fails.) And this doesn't work because it raises the ActiveRecord::StatementInvalid exception out of the transaction block without triggering an ActiveRecord::Rollback: class Person def save_with_address(address_options = {}) transaction do save! address = Address.build(address_options) address.person = self address.save! end end end The Rails documentation specifically warns against catching the ActiveRecord::StatementInvalid inside the transaction block. I guess my first question is: why isn't this transaction block... transacting on both saves?

  • Properly populating tables in an Object Relational database

I have a superclass of Communications with subclasses of Call, Text, and Data. I'm hitting a snag with properly populating these tables so that I can find the appropriate data in the various tables. My Types and Tables are declared as such: create type CommunicationType as object ( -- column names here ) not final; create type CallType under CommunicationType ( -- column names here ); create type TextType under CommunicationType ( -- column names here ); create type DataType under CommunicationType ( -- column names here ); create table Communications of CommunicationType ( -- Primary and Foreign key constraints here ); create table Calls of CallType; create table Texts of TextType; create table Datas of DataType; When I try to insert data into one of the subclasses, its entry doesn't appear in the superclass. Likewise if I insert into the superclass, it doesn't show up in the appropriate subclass. For example, insert into Calls values (CallType( -- Values -- )); doesn't show any data in Communications. Nor does insert into Communications values (CallType( -- Values -- )); show anything in Calls. What am I doing wrong?

  • Upgrade .NET 1.1 WinForm/Service to what?

    - by Conor
    Hi Folks, We have a current WinForm/Windows Service running in .NET 1.1 out on various customer sites that is getting data from internal systems, transforming it and then calling a Web Service synchronously. This client app will no longer work in Vista or Windows 7 etc.. and its time to update!! I was looking for ideas on what I could do here, I didn't write the App and I have the Business team telling me they want the world but I need to be realistic :) Things the service must be able to do: - Handle multiple formats from internal system and transform to a schema SAP, ERP etc.. - Run silently and just work on customer sites (it does currently albeit .NET 1.1) - The Customers are unable to call our web service from their sites as they are not technical enough. - Upgrade it's self when updates occur (currently don't have this capability) Is there anything I can do here other than upgrade the service to run in .NET and add a few more transformation capabilities e..g they want the customer to be able to give us a flat file, an xml file, a csv and the service transforms it and calls the Web Service? I was hoping in this day and age we could use the Web, but automating this 100% rules it out in my eyes? I could be totally wrong!! Any help would be gratefully appreciated! Cheers. Conor

  • "pushModalScreen called by a non-event thread" thrown on event thread

    - by JGWeissman
    I am trying to get my Blackberry application to display a custom modal dialog, and have the opening thread wait until the user closes the dialog screen. final Screen dialog = new FullScreen(); ...// Fields are added to dialog Application.getApplication().invokeAndWait(new Runnable() { public void run() { Application.getUiApplication().pushModalScreen(dialog); } }); This is throwing an Exception which says "pushModalScreen called by a non-event thread" despite the fact that I am using invokeAndWait to call pushModalScreen from the event thread. Any ideas about what the real problem is? Here is the code to duplicate this problem: package com.test; import net.rim.device.api.ui.*; import net.rim.device.api.ui.component.*; import net.rim.device.api.ui.container.*; public class Application extends UiApplication { public static void main(String[] args) { new Application(); } private Application() { new Thread() { public void run() { Application.this.enterEventDispatcher(); } }.start(); final Screen dialog = new FullScreen(); final ButtonField closeButton = new ButtonField("Close Dialog"); closeButton.setChangeListener(new FieldChangeListener() { public void fieldChanged(Field field, int context) { Application.getUiApplication().popScreen(dialog); } }); dialog.add(closeButton); Application.getApplication().invokeAndWait(new Runnable() { public void run() { try { Application.getUiApplication().pushModalScreen(dialog); } catch (Exception e) { // To see the Exception in the debugger throw new RuntimeException(e.getMessage()); } } }); System.exit(0); } } I am using Component Package version 4.5.0.

  • Apply CSS style to anchor problem

    - by Jake
    Using jquery I have a clicking tab mechanism that are nothing but anchor tags that return false but call javascript functions to run some events on the page. The problem is I am using jquery to apply an opacity style to the active anchor. and the other sibling anchor get a lesser opacity view. My code looks like this $("#menutab li a").click(function(){ $(this).animate({opacity:'1'},1000); $(this).siblings().animate({opacity:'.25'},1000); } I would think this code would act only on the clicked element and apply that css style to that element and the other style to the other anchor tags except the clicked one. It kind of does that, but also what it does is leave the earlier clicked element to opacity =1, so if I click an element it sets it opacity to 1 and then if I click another one it sets it opacity to 1 while leave the earlier clicked one to 1 also instead of setting it to .25 like the others. Edit: I changed the above code to: $("#menutab ul li").click(function(){ $(this).children().animate({opacity:'1'},1000); $(this).siblings().children().animate({opacity:'.25'},1000); }); and now I get the desired effect, except that when the first anchor in the list is clicked doesn't follow the event rules, When the first one is clicked its as if, the click event is not triggered, because no opacity style changes. which I don't understand.
