  • Java Swing NullPointerException when drawing

    - by juFo
    I'm using a custom JLayeredPane. I have several Shapes which needed to be drawn on different layers in the JLayeredPane. To test this I create a JPanel and ask its graphics. Then I draw a test rectangle on that JPanel (preparing the graphics) and in my paintComponent method from the JLayeredPane I finally draw everything. But this fails (NullPointerException). public class MyCustomPanel extends JLayeredPane { // test JPanel testpane; Graphics g2; // test // constructor public MyCustomPanel() { testpane = new JPanel(); this.add(testpane, new Integer(14)); g2 = testpane.getGraphics(); } @Override public void paintComponent(Graphics g) { super.paintComponent(g); g2.drawRect(10, 10, 300, 300); } } // run: //Exception in thread "AWT-EventQueue-0" java.lang.NullPointerException // at view.MyCustomPanel.paintComponent(MyCustomPanel.java:65) Why can't I draw on such a JPanel from within my JLayeredPane? I can draw directly on my JLayeredPane from within my paintComponent method but that's on the default Panel from the JLayeredPane. I need to create and draw on several layers which are added in my JLayeredPane. What am I doing wrong? :s

  • How to access generic property without knowing the closed generic type

    - by Martin Booka Weser
    I have a generic Type as follows public class TestGeneric<T> { public T Data { get; set; } public TestGeneric(T data) { this.Data = data; } } If i have now an object (which is coming from some external source) from which i know that it's type is of some closed TestGeneric<, but i don't know the TypeParameter T. Now I need to access the Data of my object. Problem is that i can't cast the object, since i don't know exactly to which closed TestGeneric. I use // thx to http://stackoverflow.com/questions/457676/c-reflection-check-if-a-class-is-derived-from-a-generic-class private static bool IsSubclassOfRawGeneric(Type rawGeneric, Type subclass) { while (subclass != typeof(object)) { var cur = subclass.IsGenericType ? subclass.GetGenericTypeDefinition() : subclass; if (rawGeneric == cur) { return true; } subclass = subclass.BaseType; } return false; } to make sure, my object is of the generic type. The code in question is as follows: public static void Main() { object myObject = new TestGeneric<string>("test"); // or from another source if (IsSubclassOfRawGeneric(typeof(TestGeneric<>), myObject.GetType())) { // the following gives an InvalidCastException // var data = ((TestGeneric<object>)myObject).Data; // if i try to access the property with reflection // i get an InvalidOperationException var dataProperty = typeof(TestGeneric<>).GetProperty("Data"); object data = dataProperty.GetValue(myObject, new object[] { }); } } I need the Data regardless of its type (well, if i could ask for its type using GetType() would be fine, but not necessary) since i just want to dump it in xml using ToString(). Any suggestions? Thanx.

  • Loading and binding a serialized view model to a WPF window?

    - by generalt
    Hello all. I'm writing a one-window UI for a simple ETL tool. The UI consists of the window, the code behind for the window, a view model for the window, and the business logic. I wanted to provide functionality to the users to save the state of the UI because the content of about 10-12 text boxes will be reused between sessions, but are specific to the user. I figured I could serialize the view model, which contains all the data from the textboxes, and this works fine, but I'm having trouble loading the information in the serialized XML file back into the text boxes. Constructor of window: public ETLWindow() { InitializeComponent(); _viewModel = new ViewModel(); this.DataContext = _viewModel; _viewModel.State = Constants.STATE_IDLE; Loaded += new RoutedEventHandler(MainWindow_Loaded); } XAML: <TextBox x:Name="targetDirectory" IsReadOnly="true" Text="{Binding TargetDatabaseDirectory, UpdateSourceTrigger=PropertyChanged}"/> ViewModel corresponding property: private string _targetDatabaseDirectory; [XmlElement()] public string TargetDatabaseDirectory { get { return _targetDatabaseDirectory; } set { _targetDatabaseDirectory = value; OnPropertyChanged(DataUtilities.General.Utilities.GetPropertyName(() => new ViewModel().TargetDatabaseDirectory)); } Load event in code behind: private void loadState_Click(object sender, RoutedEventArgs e) { string statePath = this.getFilePath(); _viewModel = ViewModel.LoadModel(statePath); } As you can guess, the LoadModel method deserializes the serialized file on the user's drive. I couldn't find much on the web regarding this issue. I know this probably has something to do with my bindings. Is there some way to refresh on the bindings on the XAML after I deserialize the view model? Or perhaps refresh all properties on the view model? Or am I completely insane thinking any of this could be done? Thanks.

  • Maintain denormalized data with NHibernate EventListener

    - by Michael Valenty
    I have one bit of denormalized data used for performance reasons and I'm trying to maintain the data with an NHibernate event listener rather than a trigger. I'm not convinced this is the best approach, but I'm neck deep into it and I want to figure this out before moving on. I'm getting following error: System.InvalidOperationException : Collection was modified; enumeration operation may not execute. System.ThrowHelper.ThrowInvalidOperationException(ExceptionResource resource) System.Collections.Generic.List`1.Enumerator.MoveNextRare() System.Collections.Generic.List`1.Enumerator.MoveNext() NHibernate.Engine.ActionQueue.ExecuteActions(IList list) NHibernate.Engine.ActionQueue.ExecuteActions() NHibernate.Event.Default.AbstractFlushingEventListener.PerformExecutions (IEventSource session) NHibernate.Event.Default.DefaultFlushEventListener.OnFlush(FlushEvent event) NHibernate.Impl.SessionImpl.Flush() NHibernate.Transaction.AdoTransaction.Commit() Here's the code to make happen: using (var tx = session.BeginTransaction()) { var business = session .Get<Business>(1234) .ChangeZipCodeTo("92011"); session.Update(business); tx.Commit(); // error happens here } and the event listener: public void OnPostUpdate(PostUpdateEvent @event) { var business = @event.Entity as Business; if (business != null) { var links = @event.Session .CreateQuery("select l from BusinessCategoryLink as l where l.Business.BusinessId = :businessId") .SetParameter("businessId", business.BusinessId) .List<BusinessCategoryLink>(); foreach (var link in links) { link.Location = business.Location; @event.Session.Update(link); } } }

    I'm totally new to flex. I'm getting a build error when using flex. That is, I've generated a .c file using flex, and, when running it, am getting this error: 1>lextest.obj : error LNK2001: unresolved external symbol "int __cdecl isatty(int)" (?isatty@@YAHH@Z) 1>C:\...\lextest.exe : fatal error LNK1120: 1 unresolved externals here is the lex file I'm using (grabbed from here): /*** Definition section ***/ %{ /* C code to be copied verbatim */ #include <stdio.h> %} /* This tells flex to read only one input file */ %option noyywrap %% /*** Rules section ***/ /* [0-9]+ matches a string of one or more digits */ [0-9]+ { /* yytext is a string containing the matched text. */ printf("Saw an integer: %s\n", yytext); } . { /* Ignore all other characters. */ } %% /*** C Code section ***/ int main(void) { /* Call the lexer, then quit. */ yylex(); return 0; } As well, why do I have to put a 'main' function in the lex syntax code?

  • Android - Widget to Play Video (onclick trouble)

    - by Josh
    I am trying to make a simple widget that will play a movie from the sdcard when clicked on. This seems simple enough, and by following tutorials I've come up with the following code, but it seems the onclick is never setup.

  • making my player sprite land on top of my platform sprite

    - by Stone
    Hi, in my XNA game(im fairly new to XNA by the way) i would like to have my player sprite land on top of a platform. i have a player sprite class that inherits from my regular sprite class, and the regular sprite class for basic non playable sprite stuff such as boxes, background stuff, and platforms. However, i am unsure how to implement a way to make my player sprite land on a platform. My player Sprite can jump and move around, but i dont know where and how to check to see if it is on top of my platform sprite. My player sprites jump method is here private void Jump() { if (mCurrentState != State.Jumping) { mCurrentState = State.Jumping; mStartingPosition = Position; mDirection.Y = MOVE_UP; mSpeed = new Vector2(jumpSpeed, jumpSpeed); } } mStartingPosition is player sprites starting position of the jump, and Position is the player sprites current position. I would think that my code for checking to see whether my player sprite is on top of my platform sprite. I am unsure how to reference my platform sprite inside of the playersprite class and inside of the jump method. i think it should be something like this //platformSprite.CollisonBox would be the rectangle around the platform, but im not //sure how to check to see if player.Position is touching any point //on platformSprite.CollisionBox if(player.Position == platformSprite.CollisionBox) { player.mDirection = 0; } Again im pretty new to programming and XNA, and some of this logic i dont quite understand so any help on any of it would be greatly appreciated:D Thanks

  • Launch User Control in a tab control dynamically

    I have a custom built menu system in which I would like to load user controls from another project into a tab control on my main project (menu control) User control Project : foobar Menu system Project : Menu The function to load them into the tab control: private void LaunchWPFApplication(string header, string pPath) { // Header - What loads in the tabs header portion. // pPath - Page where to send the user //Create a new browser tab object BrowserTab bt = tabMain.SelectedItem as BrowserTab; bt = new BrowserTab(); bt.txtHeader.Text = header; bt.myParent = BrowserTabs; //Load in the path try { Type formType = Type.GetType(pPath, true); bt.Content = (UserControl)Activator.CreateInstance(formType); } catch { MessageBox.Show("The specified user control : " + pPath + " cannot be found"); } //Add the browser tab and then focus BrowserTabs.Add(bt); bt.IsSelected = true; } And what I send to the function as an example: LaunchWPFApplication("Calculater", "foobar.AppCalculater"); But every time run, the application complains that the formType is null. I am confused on how to load the user control and curious if I'm sending the correct parameters.

  • What is the equivalent of .NET events in Ruby?

    - by Gishu
    The problem is very simple. An object needs to notify some events that might be of interest to observers. When I sat to validate a design that I cooked up now in Ruby just to validate it.. I find myself stumped as to how to implement the object events. In .Net this would be a one-liner.. .Net also does handler method signature verification,etc. e.g. // Object with events public delegate void HandlerSignature(int a); public event HandlerSignature MyEvent; public event HandlerSignature AnotherCriticalEvent; // Client MyObject.MyEvent += new HandlerSignature(MyHandlerMethod); // MyHandlerMethod has same signature as delegate Is there an EventDispatcher module or something that I am missing that I can strap on to a Ruby class ? Hoping for an answer that plays along with Ruby's principle of least surprise. An event would be the name of the event plus a queue of [observer, methodName] objects that need to be invoked when the event takes place.

  • PHP/Java Bridge - Access Java objects in PHP

    - by Omer Hassan
    I have a Red5 application which defines some public Java methods. When I start the server, an object of the application class gets created. I am trying to call the public methods of the application class from PHP using the existing instance of the Java application class. So here's my Java application: public class App extends org.red5.server.adapter.ApplicationAdapter { public boolean appStart(IScope app) { // This method gets called when the application starts // and an object of this App class is created. return true; } // This is the method I would like to call from PHP. public void f() { } } From PHP, I would like to get access to the App object that is created and call the method f() on it. I have tried playing around with this thing called "context". So in the Java method App.appStart(), I did this: // Save a reference to this App object to be retrieved later in PHP. new PhpScriptContextFactory().getContext().put("x", this); And in PHP, I tried to access the saved object like this: require_once("http://localhost:5080/JavaBridge/java/Java.inc"); var_dump(java_is_null(java_context()->get("x"))); Unfortunately, the java_is_null() function in PHP returns true. I also tried saving the App object in a static variable of App class but when I access that variable in PHP, its value is null.

  • 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); } }}

  • Change userSettings during MSI installation

    - by pagetailor
    Hi, I am trying to modify the userSettings section (Properties.MyApp.Default) in the MyApp.exe.config file during the installation using an MSI installer. I basically implemented it like in this excellent article: http://raquila.com/software/configure-app-config-application-settings-during-msi-install/ The difference is that I am not editing the appSettings but the userSettings section. The problem is that although the code runs fine, the settings are not saved. After the installation the config file contains the old settings I use in my development environment. I also tried to override OnAfterInstall(System.Collections.IDictionary stateSaver) instead of Install(System.Collections.IDictionary stateSaver) but it doesn't make a difference. Here is the code that should change the config values: protected override void OnAfterInstall(IDictionary savedState) { base.OnAfterInstall(savedState); string targetDirectory = Context.Parameters["targetdir"]; string tvdbAccountID = Context.Parameters["TVDBACCID"]; // read other config elements... Properties.Settings.Default.Tvdb_AccountIdentifier = tvdbAccountID; // set other config elements Properties.Settings.Default.Save(); } Any idea how to persist these changes? I already read about Wix but that seems like an overkill to me. Thanks in advance!

  • How do I Unit Test Actions without Mocking that use UpdateModel?

    - by Hellfire
    I have been working my way through Scott Guthrie's excellent post on ASP.NET MVC Beta 1. In it he shows the improvements made to the UpdateModel method and how they improve unit testing. I have recreated a similar project however anytime I run a UnitTest that contains a call to UpdateModel I receive an ArgumentNullException naming the controllerContext parameter. Here's the relevant bits, starting with my model: public class Country { public Int32 ID { get; set; } public String Name { get; set; } public String Iso3166 { get; set; } } The controller action: [AcceptVerbs(HttpVerbs.Post)] public ActionResult Edit(Int32 id, FormCollection form) { using ( ModelBindingDataContext db = new ModelBindingDataContext() ) { Country country = db.Countries.Where(c => c.CountryID == id).SingleOrDefault(); try { UpdateModel(country, form); db.SubmitChanges(); return RedirectToAction("Index"); } catch { return View(country); } } } And finally my unit test that's failing: [TestMethod] public void Edit() { CountryController controller = new CountryController(); FormCollection form = new FormCollection(); form.Add("Name", "Canada"); form.Add("Iso3166", "CA"); var result = controller.Edit(2 /*Canada*/, form) as RedirectToRouteResult; Assert.IsNotNull(result, "Expected to be redirected on successful POST."); Assert.AreEqual("Show", result.RouteName, "Expected to redirect to the View action."); } ArgumentNullException is thrown by the call to UpdateModel with the message "Value cannot be null. Parameter name: controllerContext". I'm assuming that somewhere the UpdateModel requires the System.Web.Mvc.ControllerContext which isn't present during execution of the test. I'm also assuming that I'm doing something wrong somewhere and just need to pointed in the right direction. Help Please!

  • StorageClientException: The specified message does not exist?

    - by Aaron
    I have a simple video encoding worker role that pulls messages from a queue encodes a video then uploads the video to storage. Everything seems to be working but occasionally when deleting the message after I am done encoding and uploading I get a "StorageClientException: The specified message does not exist." Although the video is processed, I believe the message is reappearing in the queue because it's not being deleted correctly. Is it possible that another instance of the Worker role is processing and deleting the message? Doesn't the GetMessage() prevent other worker roles from picking up the same message? Am I doing something wrong in the setup of my queue? What could be causing this message to not be found on delete? some code... //onStart() queue setup var queueStorage = _storageAccount.CreateCloudQueueClient(); _queue = queueStorage.GetQueueReference(QueueReference); queueStorage.RetryPolicy = RetryPolicies.Retry(5, new TimeSpan(0, 5, 0)); _queue.CreateIfNotExist(); public override void Run() { while (true) { try { var msg = _queue.GetMessage(new TimeSpan(0, 5, 0)); if (msg != null) { EncodeIt(msg); PostIt(msg); _queue.DeleteMessage(msg); } else { Thread.Sleep(WaitTime); } } catch (StorageClientException exception) { BlobTrace.Write(exception.ToString()); Thread.Sleep(WaitTime); } } }

  • ScriptingBridge causes iTunes to relaunch after quit

    - by Justin Voss
    I'm working on a Cocoa app that monitors what you're listening to in iTunes, and since I'm targeting Mac OS 10.5 and higher, I've decided to use Scripting Bridge. If I try to close iTunes too close to the time that my app polls it for the current track, iTunes will immediately relaunch! The only way to reliably prevent this behavior is to quit my app first, then quit iTunes. Switching to EyeTunes solves the problem, but it's a fairly old codebase and I was hoping that I could accomplish this without an external library. Surely I'm doing something wrong that's causing the relaunch? Here's some sample code; this snippet is run every few seconds, triggered by an NSTimer. #import "iTunesBridge.h" // auto-generated according to Apple's docs -(void)updateTrackInfo { iTunesApplication *iTunes = [[SBApplication alloc] initWithBundleIdentifier:@"com.apple.iTunes"]; iTunesTrack *currentTrack = [iTunes currentTrack]; // inspect currentTrack to determine what's being played... [iTunes release]; } Is this a known issue with Scripting Bridge, or am I using it incorrectly?

  • How to properly implement cheat codes?

    - by Axarydax
    Hi, what would be the best way to implement kind of cheat codes in general? I have WinForms application in mind, where a cheat code would unlock an easter egg, but the implementation details are not relevant. The best approach that comes to my mind is to keep index for each code - let's consider famous DOOM codes - IDDQD and IDKFA, in a fictional C# app. string[] CheatCodes = { "IDDQD", "IDKFA"}; int[] CheatIndexes = { 0, 0 }; const int CHEAT_COUNT = 2; void KeyPress(char c) { for (int i = 0; i < CHEAT_COUNT; i++) //for each cheat code { if (CheatCodes[i][CheatIndexes[i]] == c) { //we have hit the next key in sequence if (++CheatIndexes[i] == CheatCodes[i].Length) //are we in the end? { //Do cheat work MessageBox.Show(CheatCodes[i]); //reset cheat index so we can enter it next time CheatIndexes[i] = 0; } } else //mistyped, reset cheat index CheatIndexes[i] = 0; } } Is this the right way to do it?

  • Set Server Side OnClick() event Programmatically

    - by Corey O.
    I am looking for a way to programmatically set the OnClick event handler for a TableCell object. The ASP equivalent of what I'm trying to do will look like this: <asp:TableCell OnClick="clickHandler" runat="server">Click Me!</asp:TableCell> In the above example, "clickHandler" is a server-side function defined in the .cs CodeBehind. public virtual void clickHandler(object sender, EventArgs args) {...} However, for my situation, this TableCell object needs to be created dynamically, so setting it in an ASP tag is not an option. I am trying to do something like the following in the CodeBehind: System.Web.UI.WebControls.TableRow row = new System.Web.UI.WebControls.TableRow(); System.Web.UI.WebControls.TableCell cell = new System.Web.UI.WebControls.TableCell(); cell.Text = "Click Me!"; cell.Attributes.Add("onClick", "clickHandler"); row.Cells.Add(cell); Unfortunately, in this situation: cell.Attributes.Add("onClick", "clickHandler"); the "clickHandler" only works as a client-side javascript function. What I'm looking for is a way to link the server-side clickHandler() function, defined in the .cs CodeBehind, to this table cell. After an afternoon of searching, I have been unable to come up with a working solution. Thanks in advance for any help.

  • Partial template specialization on a class

    - by Jonathan Swinney
    I'm looking for a better way to this. I have a chunk of code that needs to handle several different objects that contain different types. The structure that I have looks like this: class Base { // some generic methods } template <typename T> class TypedBase : public Base { // common code with template specialization private: std::map<int,T> mapContainingSomeDataOfTypeT; } template <> class TypedBase<std::string> : public Base { // common code with template specialization public: void set( std::string ); // functions not needed for other types std::string get(); private: std::map<int,std::string> mapContainingSomeDataOfTypeT; // some data not needed for other types } Now I need to add some additional functionality that only applies to one of the derivative classes. Specifically the std::string derivation, but the type doesn't actually matter. The class is big enough that I would prefer not copy the whole thing simply to specialize a small part of it. I need to add a couple of functions (and accessor and modifier) and modify the body of several of the other functions. Is there a better way to accomplish this?

  • Why do i get exc bad access in cases when object is not nil?

    - by DixieFlatline
    I have an app that receives remote notifications. My view controller that is shown after push has a tableview. App crashes very randomly (1 in 20 tries) at line setting frame: if (!myTableView) { NSLog(@"self.myTableView is nil"); } myTableView.frame=CGRectMake(0, 70, 320, 376); This only happens when i open the app, then open some other apps and then receive the push notification. I guess it has something to do with memory. I use ARC (ios 5). The strange thing is that nslog is not displayed, so tableview is not nil. Crash log: Exception Type: EXC_BAD_ACCESS (SIGSEGV) Exception Codes: KERN_INVALID_ADDRESS at 0x522d580c Crashed Thread: 0 Thread 0 name: Dispatch queue: com.apple.main-thread Thread 0 Crashed: 0 libobjc.A.dylib 0x352b1f7e objc_msgSend + 22 1 Foundation 0x37dc174c NSKVOPendingNotificationCreate + 216 2 Foundation 0x37dc1652 NSKeyValuePushPendingNotificationPerThread + 62 3 Foundation 0x37db3744 NSKeyValueWillChange + 408 4 Foundation 0x37d8a848 -[NSObject(NSKeyValueObserverNotification) willChangeValueForKey:] + 176 5 Foundation 0x37e0ca14 _NSSetPointValueAndNotify + 76 6 UIKit 0x312af25a -[UIScrollView(Static) _adjustContentOffsetIfNecessary] + 1890 7 UIKit 0x312cca54 -[UIScrollView setFrame:] + 548 8 UIKit 0x312cc802 -[UITableView setFrame:] + 182 9 POViO 0x000913cc -[FeedVC viewWillAppear:] (FeedVC.m:303) Dealloc is not called because it is not logged: - (void)dealloc { NSLog(@"dealloc"); }

  • Broadcasting an intent to a specific component.

    - by Nic Strong
    I have an activity that is starting a background operation in another service. This activity receives various notifications from this service. As part of the intent I use to initiate the background operation I pass extra data with the context of my activity so the background service can broadcast intents back to me (the download service is a good example of this usage). So in the activity I use the following to attach the context: intent.putExtra(Intents.EXTRA_NOTIFICATION_PACKAGE, IntentTestActivity.this.getPackageName()); intent.putExtra(Intents.EXTRA_NOTIFICATION_CLASS, IntentTestActivity.class.getCanonicalName()); intent.putExtra(Intents.EXTRA_NOTIFICATION_EXTRAS, myContext); I register for the notifications in the activity: IntentFilter intentFilter = new IntentFilter(); intentFilter.addAction(Intents.ACTION_NOTIFICATION); intentFilter.addCategory(Intents.CATEGORY_COMPLETION); intentFilter.addCategory(Intents.CATEGORY_PROGRESSS); Intent intent = registerReceiver(receiver, intentFilter); In the background service I send notifications with the following code: void broadcastNotification(String action, String category, String packageName, String className, String extras, int operationResult) { Intent intent = new Intent(action); intent.addCategory(category); intent.setClassName(packageName, className); if (extras != null) { intent.putExtra(Intents.EXTRA_NOTIFICATION_EXTRAS, extras); } intent.putExtra(Intents.EXTRA_OPERATION_RESULT, operationResult); context.sendBroadcast(intent); } My problem is that the above broadcast will never be received. If however I comment out the line intent.setClassName(packageName, className); Then the broadcast is received. Is it a problem with my filter? Do I have to specify intents intended for a specific component? Or cannot I not use such fine grain control over the delivery of broadcasts. Thanks, Nic
