dispatcher

In backbone.js documentation it says: To make a handy event dispatcher that can coordinate events among different areas of your application: var dispatcher = _.clone(Backbone.Events) Can anyone explain how to implement the dispatcher to communicate from one view to another? Where do I have to place the code in my app? Paul Hoenecke Here is a good article about using an event aggregator . Can anyone explain how to implement the dispatcher to communicate from one view to another? Where do I have to place the code in my app? You will probably have some kind of App Controller object, which will

I'm getting "An object reference is required for the non-static field, method, or property 'System.Windows.Threading.Dispatcher.BeginInvoke(System.Action)'" for this code. private void ResponseCompleted(IAsyncResult result) { HttpWebRequest request = result.AsyncState as HttpWebRequest; HttpWebResponse response = request.EndGetResponse(result) as HttpWebResponse; using (StreamReader sr = new StreamReader(response.GetResponseStream())) { Dispatcher.BeginInvoke( () => { try { XDocument resultsXml = XDocument.Load(sr); QueryCompleted(new QueryCompletedEventArgs(resultsXml)); } catch (XmlException

I have created a .NET Windows Service which performs certain actions and generates reports. These reports are XPS documents which I save in a certain directory. Being familiar with WPF, the way I have chosen to create the reports is to instantiate a System.Windows.Documents.FixedDocument , adding FixedPage objects with content as required. My problem is that the Service memory usage goes up and up and up over time as it runs. At first, I went through my code rigorously, ensuring all disposable objects were disposed, etc, and other obvious memory leak candidates, but still had the problem. I

Im working on a WPF application. I have a label called "Status_label" in MainWindow.xaml . and I want to change its content from a different class (signIn.cs). Normally I'm able to do this var mainWin = Application.Current.Windows.Cast<Window>().FirstOrDefault(window => window is MainWindow) as MainWindow; mainWin.status_lable.Content = "Irantha signed in"; But my problem is,when I'm trying to access it via different thread in signIn.cs class, it gives an error: The calling thread cannot access this object because a different thread owns it. Can I solve this by using Dispatcher.Invoke(new

I have problem with update listbox from view model class. I use Caliburn Micro framework. My scenario is here: I bind property of type bindableCollection on listbox: Code from view model: private BindableCollection<UserInfo> _friends; public BindableCollection<UserInfo> Friends { get { return _friends; } set { _friends= value; NotifyOfPropertyChange(()=>Friends); } } In view model I create fake service method wich return new fresh data as List and with this data I update property Friends which is bind on listbox. I call fake service method in dispatcher timer tick event every 3 seconds.

I want to configure Kamailio server so that traffic will be forwarded to other four asterisk servers equally.

Here is the kamailio.cfg that I am using. #!KAMAILIO #!define WITH_MYSQL #!define WITH_AUTH #!define WITH_USRLOCDB #!define WITH_NAT #!define WITH_ASTERISK # *** Value defines - IDs used later in config #

I think I need some help understanding the Dispatcher Queue . When new work arrives it gets added at the beginning of the dispatcher queue and when the Dispatcher wants to process a working item it gets removed from the beginning. In more general terms: If there is work it gets stored in a FIFO manner inside the queue and processed as long there is no work left. The MSDN documentation here is referring to a loop and a frame : The Dispatcher processes the work item queue in a loop. The loop is referred to as a frame. But where is a loop in this context ? For me a loop is something that iterates
