  • Selenium onChange not working

    - by tohop
    Hi, I have tried a number of things to try and get Selenium to pick up an 'onchange' event from a drop down menu, none of which has worked. The offending HTML is: <select onchange="doOpperation(this.options[this.selectedIndex]); this.selectedIndex = 0;" name="opps_ondemand" id="opps_ondemand"> <option value="none" id="ondemand">Mark as...</option> <option cmd="blah1" value="add">Something</option> <option cmd="blah2" value="remove">None</option> </select> I have read that Selenium IDE doesn't record some on* events, and so it would be wise to use fireEvent(): $this->click("opps_ondemand"); $this->select("opps_ondemand", "label=Mark as..."); $this->click("//option[@value='add']"); sleep(3); $this->fireEvent("//select[@id='opps_ondemand']", "change"); However, this does not work (with or without the fireEvent). I have also tried using $this->fireEvent("locator", "click"); instead of $this->click("locator"); but this did nothing. Selenium does not complain about these locators not existing so I am assuming it can see the select/option elements fine. The problem seems to be the onChange event. Does anyone know how to resolve this? Thanks.

  • How do I pass an array of structs (containing std:string or BSTR) from ATL to C#. SafeArray? Varian

    - by Andrew
    Hi, I have an ATL COM object that I am using from C#. The interface currently looks like: interface ICHASCom : IDispatch{ [id(1), helpstring("method Start")] HRESULT Start([in] BSTR name, [out,retval] VARIANT_BOOL* result); ... [id(4), helpstring("method GetCount")] HRESULT GetCount([out,retval] LONG* numPorts); ... [id(7), helpstring("method EnableLogging")] HRESULT EnableLogging([in] VARIANT_BOOL enableLogging); }; That is, it's a very simple interface. I also have some events that I send back too. Now, I would like to add something to the interface. In the ATL I have some results, which are currently structs and look like struct REPORT_LINE { string creationDate; string Id; string summary; }; All the members of the struct are std::string. I have an array of these that I need to get back to the C#. What's the best way to do this? I suspect someone is going to say, "hey, you can't just send std::string over COM like that. If so, fine, but what's the best way to modidfy the struct? Change the std::string to BSTR? And then how do I, 1) Set up the IDL to pass an array of structs (structs with BSTR or std::string) 2) If I must use SAFEARRAYS, how do I fill the SAFEARRAYS with the structs. I'm not familiar with COM except for use with simple types. Thanks, Dave

  • jQuery problem with change event and IE8

    - by Marcus
    There is a bug in jQuery 1.4.2 that makes change event on select-element getting fired twice when using both DOM-event and a jQuery event, and this only on IE7/8. Here is the test code: <html> <head> <script src="http://code.jquery.com/jquery-1.4.2.js" type="text/javascript"></script> <script type="text/javascript"> jQuery(document).ready(function() { jQuery(".myDropDown").change(function() { }); }); </script> </head> <body> <select class="myDropDown" onchange="alert('hello');"> <option>1</option> <option>2</option> <option>3</option> <option>4</option> </select> </body> </html> Ticket to actual bug: http://dev.jquery.com/ticket/6593 This causes alot of trouble for us in our application cause we use both ASP.NET-events mixed with jQuery and once you hook up a change event on any element every select (dropdown) gets this double firing problem. Is there anyone who knows a way around this in the meantime until this issue is fixed?

  • wxWidgets EVT_KILL_FOCUS

    - by Wallter
    Q1:I am using wxWidgets (C++) and have come accost a problem that i can not locate any help. I have created several wxTextCtrl boxes and would like the program to update the simple calculations in them when the user 'kills the focus.' I could not find any documentation on this subject on the wxWidgets webpage and Googling it only brought up wxPython. The two events i have found are: EVT_COMMAND_KILL_FOCUS - EVT_KILL_FOCUS for neither of which I could find any snippet for. Could anyone give me a short example or lead me to a page that would be helpful? Q2:Would i have to create an event to handle the focus being killed for each of my 8 wxTextCtrl boxes? In the case that i have to create a different event: How would i get each event to differentiate from each other? Will i have to create new wxID's for each of the wxTextCtrl boxes? class BasicPanel : public wxPanel { ... wxTextCtrl* one; wxTextCtrl* two; wxTextCtrl* three; wxTextCtrl* four; ... }

  • Delete NSManageObject at the event tableView:commitEditingStyle:forRowAtIndexPath:

    - by David.Chu.ca
    I got exception when I tried to delete one NSManageObject at the event of tableView:commitEditingStyle:forRowAtIndexPath:. Here is the part of my codes: - (void)tableView:(..)tableView commitEditingStyle:(..)editingStyle forRowAtIndexPath:(..)indexPath { if (editingStyle == UITableViewCellEditingStyleDelete) { [managedObjectContext deleteObject: [fetchedResultController objectAtIndexPath:indexPath]]; ... } } The exception was thrown at the line of deleteObject:(method of my local NSManagedObjectContext). This is the exception message: uncaught exception 'NSObjectInaccessibleException', reason: 'The NSManagedObject with ID:0x3d07a30 <x-coredata://0D2CC9CB-042B-496D-B3FE-5F1ED64EAB97/paymentType/p2> has been invalidated.' I tried to get entity object first and then to delete it. The entity looks OK but still the exception was at delete: NSManagedObject *entityToDelete = [fetchedResultsController objectAtIndexPath:indexPath]; [mangedObjectContext deleteObject:entityToDelete]; // Exception again. I am not sure if the entity object retrieved from the fetchedResultsController(NSFetchedResultsController type) cannot be deleted? If so, is there any other way to get the entity object for deleting? I found that in the Apple's Core Data Tutorial for iPhone with events example, there is on NSArray to hold event entity objects. I am not sure if that's necessory to use NSArray to hold my local entity objects and then use it for deleting?

  • Core Data + Core Animation/CALayer together??

    - by ivanTheTerrible
    I am making an Cocoa app with custom interfaces. So far I have implemented one version of the app using CALayer doing the rendering, which has been great given the hierarchical structure of CALayers, and its [hitTest:] function for handling mouse events. In this early version, the model of the app are my custom classes. However, as the program grows I feel the urge of using Core Data for the model, not just for the ease of binding/undo management, but also want to try out the new technology. My method so far: In Core Data: creating a Block entity, with attributes xPos, yPos, width, height...etc. Then, creating a BlockView : CALayer class for drawing, which uses methods such as self.position.x = [self valueForKey:@"xPos"] to fetch the values from the model. In this case, every BlockView object has to also keep a local copy of xPos, which is NOT good. Do any of you guys have better suggestions? Edit: This app is a information visualization tool. So the positions, dimensions of the blocks are important, and should be persisted for later analysis.

  • BlazeDS StreamingAMF: How to detect when flex client closes the connection?

    - by Adrian Pirvulescu
    Hello, I have a Flex application that connects to a BlazeDS server using the StreamingAMF channel. On the server-side the logic is handled by a custom adapter that extends ActionScriptAdapter and implements FlexSessionListener and FlexClientListener interfaces. I am asking how can I detect which "flex-client" has closed a connection when for example the user is closing the browser? (so I can clean some infos inside the database) I tried using the following: 1. To manually manage the command messages: @Override public Object manage(final CommandMessage commandMessage) { switch (commandMessage.getOperation()) { case CommandMessage.SUBSCRIBE_OPERATION: System.out.println("SUBSCRIBE_OPERATION = " + commandMessage.getHeaders()); break; case CommandMessage.UNSUBSCRIBE_OPERATION: System.out.println("UNSUBSCRIBE_OPERATION = " + commandMessage.getHeaders()); break; } return super.manage(commandMessage); } But the clientID's are always different from the ones that came. 2. Listening for sessionDestroyed and clientDestroyed events @Override public void clientCreated(final FlexClient client) { client.addClientDestroyedListener(this); System.out.println("clientCreated = " + client.getId()); } @Override public void clientDestroyed(final FlexClient client) { System.out.println("clientDestroyed = " + client.getId()); } @Override public void sessionCreated(final FlexSession session) { System.out.println("sessionCreated = " + session.getId()); session.addSessionDestroyedListener(this); } @Override public void sessionDestroyed(final FlexSession session) { System.out.println("sessionDestroyed = " + session.getId()); } But those sessionDestroyed and clientDestroyed methods are never called. :(

  • WPF/SL EventAggregator implementation with durable subscribers behavior?

    - by sha1dy
    Hi. Currently I'm building an application using latest Prism for Silverlight 4. I've a module and in that module I've two views with view models. Also I've a module view with two regions for each view. In module initialization I'm registering my views and view models in Unity container and also register views with corresponding regions. The problem is that views should display something similar to table-detail information - first view shows available entities ans the second view shows detail of selected entity. I need a way how to pass them initial selected entity. Newly created first view doesn't have any selected entity and newly created second view doesn't show any details. Currently I'm doing that this way: In module I create two view models and register them as instances in Unity container and then I register views as types for corresponding regions. Each view subscribes to EntitySelectedEvent from EventAggregator. Module initializer publish this event after initialization and this way two views are selecting the same entity. I know this looks ugly - I tried publishing this event from one of view models but the problems is that EventAggregator in Prism doesn't support durable subscribers - this means that if the second view model didn't subscribe to event before the first view model fired it, it won't receive and event. I know this is a normal behavior of EventAggregator, but I'm looking for a solution when view models can fire events without depending on initialization order of them - that is the first model can fire event before the second model was created and the second model will receive this 'queued' event after subscribing to it. Are there any other messaging implementations for WPF/SL which do support such behavior or using a mediator (in my example it's a module itself) isn't such a bad idea after all? One big problem with mediator is that models must be created right away in initialize and they can't be registered as types in container because this leads again to missing subscribers.

  • Nginx not responding to remote IP

    - by bucabay
    I just installed Nginx listening on 8083 I can get a HTTP response when sending a HTTP request from the local machine. eg: curl -i localhost:8083 However, when I do the same from a remote machine, it just hangs until the ssh times out, or when the browser times out if accessed from the browser. I pretty much have the default config: user apache apache; worker_processes 1; error_log logs/error.log; #error_log logs/error.log notice; #error_log logs/error.log info; pid logs/nginx.pid; events { worker_connections 1024; } http { include mime.types; default_type application/octet-stream; log_format main '$remote_addr - $remote_user [$time_local] "$request" ' '$status $body_bytes_sent "$http_referer" ' '"$http_user_agent" "$http_x_forwarded_for"'; access_log logs/access.log main; sendfile on; tcp_nopush on; #keepalive_timeout 0; keepalive_timeout 65; #gzip on; server { listen 8083; server_name _; charset utf-8; #access_log logs/host.access.log main; location / { root html; index index.html index.php; } #error_page 404 /404.html; # redirect server error pages to the static page /50x.html # error_page 500 502 503 504 /50x.html; location = /50x.html { root html; } location ~ /\.ht { deny all; } } } any ideas?

  • How do you jump to a particular row in a DataGridView by typing (a la Windows Explorer details view)

    - by russcollier
    I have a .NET Winforms app in C# with a DataGridView that's read-only and populated with some number of rows. I'd like to have functionality similar to Windows Explorer's (and many other applications) details view for example. I'd like the DataGridView to behave such that when it has focus if you start typing, the current row selection will jump to the row where the (string) value of cell 0 (i.e. the first column in the row) starts with the characters you typed in. For example, if I have a DataGridView with 1 column and the following rows: Bob Jane Jason John Leroy Sam If the DataGridView has focus and I hit the 'b' key on my keyboard, the selected row is now "Bob". If I quickly type in the keys 'ja', the selected row is Jane. If I quickly type in the letters 'jas', the selected row is Jane. If I hit the 'z' key, nothing is selected (since nothing starts with Z). Likewise if Jane is currently selected and I keep typing the letter 'j', the selection will cycle through to Jason, then John, then back to Jane, each time I hit the 'j' key. I've been doing some Googling (and "stackoverflowing" :-)) for awhile and cannot find any examples of this type of functionality. I have a rough idea in my head to do this via some sort of short lived timer thread, collecting the keystrokes on KeyPress events for the DataGridView, and selecting rows based on those collected keystrokes matching a Cells[0].Value.StartsWith() type of condition. But it seems like there has to be an easier way that I'm just not seeing. Any ideas would be much appreciated. Thanks!

  • full duplex communication over the web w/o flash sockets

    - by aharon
    A web application I'm helping to develop is faced with a well-known problem: we want to be able to let users know of various events and so forth that can occur at any time, essentially at random, and update their view accordingly. Essentially, we need to allow the server to push requests to individual clients, as opposed to the client asking the server. I understand that WebSockets are an effort to address the problem; however, after a bit of looking around into them, I understand that a) very few web browsers currently offer native websocket support; b) to get around this, you either use flash sockets or some sort of AJAX long-polling; c) a special websockets server must be used. Now, we want to offer our service without Flash. And any sort of servers must have some sort of load-balancing capabilities, or at least some software that can do load balancing for them. As of 2008, everyone was saying that Comet-based solutions (e.g., Bayeux) were the way to go for these sort of situations. However, the various protocols seem to have not had much work put into them since then—which leads (finally) to the question. Is Bayeux-flavored Comet still the right tool for jobs like this? If not, what is?

  • Jquery event to fire in ajax loaded content, IE & FF problem

Here is my code :- <li><a href="#" id="subtopic">Title</a></li> <script type="text/javascript"> $(function() { $("#subtopic").click(function() { url: test.html ,success: function(data) { $('#result').html(data); $(".filetree").treeview(); $('#result').click(); $('#result').trigger("update"); } }); }); }); </script> In my loaded content, :- <a href="#" id="addSubTopic">Click here</a> <script type="text/javascript"> $(document).ready(function() { alert("000"); }); $(function() { $("#addSubTopic").click(function() { alert("0"); $.ajax({ url: url, success: function(data) { $("#listRes").append(data); } }); }); }); </script> In IE, it works fine, the click works and I can get the "alert" but in Firefox, the whole thing just go dead.

  • Logging with Quartz.net

    - by Young Ninja
    I will shamelessly state that I have little experience with Log4Net... I only just installed it, but it won't capture log events from Quartz.net, which is a scheduling library. Apparently Quartz.net uses Commons Logging and that needs to be configured to point to my Log4Net settings. Unfortunately, it doesn't seem to work. Help is appreciated: <configSections> ... <section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net" /> <section name="quartz" type="System.Configuration.NameValueSectionHandler, System, Version=1.0.5000.0,Culture=neutral, PublicKeyToken=b77a5c561934e089" /> <section name="commonLogging" type="Common.Logging.ConfigurationSectionHandler, Common.Logging"/> </configSections> <!-- Log4net error handling --> <log4net> <appender name="LogFileAppender" type="log4net.Appender.FileAppender"> <param name="File" value="Admin/LabSlice.log" /> <param name="AppendToFile" value="true" /> <layout type="log4net.Layout.PatternLayout"> <param name="ConversionPattern" value="%d [%t] %-5p %c %m%n" /> </layout> </appender> <root> <level value="INFO" /> <appender-ref ref="LogFileAppender" /> </root> </log4net> <!-- Commons logging (Quart.net logs) --> <commonLogging> <logging> <factoryAdapter type="Common.Logging.Log4Net.Log4NetLoggerFactoryAdapter, Common.Logging.Log4net"> <arg key="configType" value="INLINE" /> </factoryAdapter> </logging> </commonLogging>

  • Circular dependecy in winforms app using Castle Windsor

    - by Sven
    Hello, I was experimenting a little bit with Castle winforms in a winforms project. I wanted to register all my form dependencies with Castle windsor. This way I would have a single instance for all my forms. Now I have some problem though. I'm in a situation that form x has a dependency on form y and form y has a dependency on form x. Practical example maybe: form x is used to create an order, form y is the screen that has a list of customers. From form x there is a button to select a customer for the order. This will open form y where ou can search the customer. There is a button that lets you add the found customer to the order. It will call a method on form x and passes the selected customer object. I could do this with events. Raise an event in form y and listen for that in form x. But isn't there a way around the circular dependency in Castle Windsor, lazy registration or something? Can anyone help me out? Thanks in advance

  • iOS 5 Audio Alarms Don't Sound Without kAudioSessionProperty_OverrideCategoryMixWithOthers On

    - by coneybeare
    I have an audio app that is having some problems with the way iOS 5 has changed audio behaviors. When my app's audio is playing (AVAudioSessionCategoryPlayback), and a Clock.app alarm or timer is fired from the OS, the UIAlertView notification pops up, but without the audio alert. My application sound ducks fine to get out of the way of the audio alert, but the alarm app's audio alert does not sound. Naturally, tons of support requests poured in over the iOS 5 change. I have solved this temporarily by setting kAudioSessionProperty_OverrideCategoryMixWithOthers which lets the alarm audio come through, but there are a few very undesirable side-effects when doing this: Other app's audio can play with/over mine. The remote control events are not routed to my app, but to iPod.app. None of the above drawbacks are acceptable for my app's requirements. I have been hacking away at this for some time now but haven't been able to crack it. How can I setup my audio such that: My app's audio still uses the AVAudioSessionCategoryPlayback category for background audio. The Clock.app alarms still have their audio alerts make sound The app still responds to remote control notifications

  • AS3: Array of objects parsed from XML remains with zero length

    - by Joel Alejandro
    I'm trying to parse an XML file and create an object array from its data. The data is converted to MediaAlbum classes (class of my own).

  • Interception with Unity in Prism v2 for WPF (not working for me)

    - by Bobby Chopra
    I cannot get interception to work with Prism v2 (Oct 2009). I am trying to intercept the Setter for any Public Properties and then fire the PropertyChanged event if the property has changed. I can see that the code gets executed (by stepping through with the debugger or adding a debug point). However, the WPF Window controls that are bound to these properties do not get updated. If I subscribe to these events and print to the console, I can print out the property change notifications. So, if the View has a textbox, which updates the property on the ViewModel, then the property in the ViewModel gets updated. However, if a button on the view (implemented as a DelegateCommand) causes the property to get updated, then the textbox (TwoWay Binding Mode) that is bound to that Property is not updated even though the event is triggered and the console has printed out the information about which property was updated. Has anyone encountered this issue? Here is the sample WPF Application that I have written. Wordpress doesn't allow uploads of zip files, so I renamed it to have a pdf extension (rename the file to have a zip extension). Please let me know what I am doing wrong. Thanks in advance.

  • Any good tools or tips for fuzz testing Windows forms applications?

    - by Ogre Psalm33
    I'm maintaining a ~300K LOC C# legacy thick-client application with a Windows.Forms interface. The app is full of little bugs and quirks. For example, I recently discovered a bug where if a users edits and tabs (not clicks) through cells on a DataViewGrid, and leaves the a certain cell selected, the app gets an "Object reference not set to an instance of an object" exception. I discover (or get a bug report of) something new like this about every week or two. I've had enough, and was thinking of trying some sort of fuzz testing on the application to try to ferret out undiscovered issues. If I roll-my-own fuzz testing, I'd assume I at least need to be able to generate test harnesses that run pieces of my app (main window, FormX, FormY, FormZ, ...) independently and try to inject events into them. I was trying to look for tools suited for this, but so far have come up with nothing for Win Forms. (There seems to be no shortage of fuzz testing tools for web apps, however). Any helpful ideas?

  • Does anyone know of a good Commercial WPF Web Browser Control?

    - by VoidDweller
    I have an MDI WPF app that I need to add web content too. At first, great it looks like I have 2 options built into the framework the Frame control and the WebBrowser control. Given that this is an MDI app it doesn't take long to discover that neither of these will work. The WebBrowser control wraps up the IE WebBrowser ActiveX Control which uses the Win32 graphics pipeline. The "Airspace" issue pretty much sums this up as "Sorry, the layouts will not play nice together". Yes, I have thought about taking snapshots of the web content rendering these and mapping the mouse and keyboard events back to the browser control, but I can't afford the performance penalty and I really don't have time to write and thoroughly test it. I have looked for third party controls, but so far I have only found Chris Cavanagh's WPF Chromium Web Browser control. Which wraps up Awesomium 1.5. Together these are very cool, they play nice with the WPF layouts. But they do not meet my performance requirements. They are VERY HEAVY on memory consumption and not to friendly with CPU usage either. Not to mention still quite buggy. I'll elaborate if you are interested. So, do any of you know of a stable performant WPF web browser control? Thanks.

  • Accessing class member variables inside a BackgroundWorker's DoWork event handler, and other Backgro

    - by Justin
    Question 1 In the DoWork event handler of a BackgroundWorker, is it safe to access (for both reading and writing) member variables of the class that contains the BackgroundWorker? Is it safe to access other variables that are not declared inside the DoWork event handler itself? Obviously DoWork should not be accessing any UI objects of, say, a WinForms application, as the UI should only be updated from the UI thread. But what about accessing other (not UI-related) member variables? The reason why I ask is that I've seen the occasional comment come up while Googling saying that accessing member variables is not allowed. The only example I can find at the moment is a comment on this MSDN page, which says: Note, that the BGW can cause exceptions if it attempts to access or modify class level variables. All data must be passed to it by delegates and events. And also: NEVER. NEVER. Never try to reference variables not declared inside of DoWork. It may seem to work at times, but in reality you are just getting lucky. As far as I know, MSDN itself does not document any restrictions of this kind (although if I'm wrong, I'd appreciate a link). But comments like these do seem to pop up every now and again. (Of course if DoWork does access/modify a member variable that could be accessed/modified by the main thread at the same time, it is necessary to synchronise access to that field, eg by using a locking object. But the above quotes seem to require a blanket ban of accessing member variables, rather than just synchronising access!) Question 2 To make this into a more general question, are there any other (not documented?) restrictions that users of the BackgroundWorker should be aware of, aside from the above? Any "best practices", perhaps?

  • ASP.NET MVC Strongly Typed Widgets

    - by Ben
    I have developed a plugin system that makes it easy to plug in new logic to an application. Now I need to provide the ability to easily add UI widgets. There are already some good responses on how to create a portal system (like iGoogle) with ASP.NET MVC, and I'm fine about the overall concept. My question is really about how we make strongly typed widgets. Essentially when we set up a widget we define the controller and action names that are used to render that widget. We can use one controller action for widgets that are not strongly typed (since we just return PartialView(widgetControlName) without a model) For widgets that are strongly typed (for example to an IList) we would need to add a new controller action (since I believe it is not possible to use Generics with ActionResult e.g. ActionResult). The important thing is that the widget developers should not change the main application controllers. So my two thoughts are this: Create new controllers in a separate class library Create one partial WidgetController in the main web project and then extend this in other projects (is this even possible?) - not possible as per @mfeingold As far as the development of the widgets (user controls) go, we can just use post build events from our extension projects to copy these into the Views/Widgets directory. Is this a good approach. I am interested to here how others have handled this scenario. Thanks Ben P.S - in case it helps, an example of how we can render widgets - without using Javascript <%foreach (var widget in Model) {%> <%if (widget.IsStronglyTyped) { Html.RenderAction(widget.Action, widget.Controller); } else { Html.RenderPartial(widget.ControlName); } %> <%} %>

  • viewstack causing error 1065 variable not defined issue?

    - by jason
    I've got an flex application where I have a left side TREE control and a viewstack on the right and when someone selects the tree it loads the named viewstack based on the hidden node value of the XML of the tree. But it's throwing a error 1065 variable not defined on a viewstack which worked on the last browser refresh/reload. It's not related to a particular viewstack from what I can tell it just seems to throw the error on certain render events. I've tried to use creationpolicy="all" on the viewstack but it seems to not be of any help. public function treeChanged(event:Event):void { selectedNode=Tree(event.target).selectedItem as XML; //trace(selectedNode.@hidden); //Alert.show([email protected]() + " *"); if([email protected]() == '' || [email protected]() == null){ //Alert.show("NULL !"); return; } mainviewstack.selectedChild = Container(mainviewstack.getChildByName([email protected]())); //Container(mainviewstack.getChildByName(selectedNode.@hidden)); If I add in an alert box before the getchildbyname option the viewstack has time to render and everything works fine, so it leads me to believe the app is not giving it enough time to load the viewstack?

  • How can I scale an OSMF player in ActionScript 3/Flex

    - by Greg Hinch
    I am trying to create a simple video player SWF using the open source media framework in Flex 4. I want to make it dynamically scale based on the dimensions of the video, input by the user. I am following the directions on the Adobe help site, but the video does not seem to scale properly. Depending on the size, sometimes videos play larger than the space allotted on the webpage, and sometimes smaller. The only way I have been able to get it to work properly is by including a SWF metadata tag hardcoding the width and height, but I can't use that if I want to make the player dynamically sized. My code is : package { import flash.display.Sprite; import flash.events.Event; import org.osmf.media.MediaElement; import org.osmf.media.MediaPlayer; import org.osmf.media.URLResource; import org.osmf.containers.MediaContainer; import org.osmf.elements.VideoElement; import org.osmf.layout.LayoutMetadata; public class GalleryVideoPlayer extends Sprite { private var videoElement:VideoElement; private var mediaPlayer:MediaPlayer; private var mediaContainer:MediaContainer; private var flashVars:Object; public function GalleryVideoPlayer() { if (stage) init(); else addEventListener(Event.ADDED_TO_STAGE, init); } private function init(e:Event = null):void { removeEventListener(Event.ADDED_TO_STAGE, init); flashVars = loaderInfo.parameters; mediaPlayer = new MediaPlayer(); videoElement = new VideoElement(new URLResource(flashVars.file)); mediaContainer = new MediaContainer(); var layoutMetadata:LayoutMetadata = new LayoutMetadata(); layoutMetadata.width = Number(flashVars.width); layoutMetadata.height = Number(flashVars.height); videoElement.addMetadata(LayoutMetadata.LAYOUT_NAMESPACE, layoutMetadata); mediaPlayer.media = videoElement; mediaContainer.addMediaElement(videoElement); addChild(mediaContainer); } }}

  • Update panel and usercontrols

    - by Charlie Brown
    I have two web user controls nested inside of an update panel. The events inside the user controls do not appear to trigger the panel. For testing, I have set the method the fires to sleep for 3 seconds, and added an update progress panel to the page. The update progress panel never comes up and the page reflashes as usual. The user controls work correctly and do what they need to do, but I would like to make them ajaxy and pretty. Is there a special method for adding usercontrols to an update so the postback works correctly? <asp:ScriptManager ID="ScriptManager1" runat="server"> </asp:ScriptManager> <asp:UpdateProgress ID="UpdateProgress1" runat="server" DisplayAfter="100"> <ProgressTemplate> UPDATING...</ProgressTemplate> </asp:UpdateProgress> <asp:UpdatePanel ID="UpdatePanel1" runat="server"> <ContentTemplate> <div id="order"> <keg:BeerList runat="server" ID="uxBeerList" /> <kegcart:ShoppingCart runat="server" ID="uxCustomerCart" /> <br class="clearfloat" /> </div> </ContentTemplate> </asp:UpdatePanel> Protected Sub uxBeerList_AddItem(ByVal item As KegData.IOrderableItem) Handles uxBeerList.AddItem uxCustomerCart.AddItemToOrder(item) System.Threading.Thread.Sleep(5000) End Sub
