dispatcher

I need to invoke method runed on timer thread on right working thread. Invoke/BeginInvoke process is working for me. There are 2 threads which shares one inter thread data container for data exchange. One is filling queue, one shuld process the queue. Queue raises event if it is filled after empty state. All the problem is caused by timer, which open new thread on its elapsed event. I am using Dispatcher to dispatch on the right thread, but everything works, except this Dispatcher. :-) Please, does anybody see where the problem is? Complete test code is here: http://pastebin.com/jqYbR9PS .

I want adding items to DataGrid in thread. I have view model for my user control: public class Contact { public string Name { get; set; } public string Phone { get; set; } } public class ContactGridViewModel { public ContactGridViewModel() { Items = new ObservableCollection<Contact>(); } public ObservableCollection<Contact> Items { get; private set; } public Dispatcher Dispatcher { get { return Dispatcher.CurrentDispatcher); } } private DispatcherOperation LastOperation { get; set; } public void Update(IEnumerable<Contact> contacts) { if (LastOperation != null) LastOperation.Abort(); Items

I have a problem with thread.When I want set a GridView into a ListView as View in another thread.It display a message which said: Must create DependencySource on same Thread as the DependencyObject. // Create grid view GridView grid = new GridView(); // Add column // Name grid.Columns.Add((GridViewColumn)myresourcedictionary["gridDirFileName"]); // Type grid.Columns.Add((GridViewColumn)myresourcedictionary["gridDirFileType"]); // Data Modified grid.Columns.Add((GridViewColumn)myresourcedictionary["gridDirFileDataModified"]); // Size grid.Columns.Add((GridViewColumn)myresourcedictionary[

I have a call to a method that returns a UIElement that I call using the Dispatcher , below is the code. However the return value of the Dispatcher invoke is always NULL, any ideas? void backgroundWorker_DoWork(object sender, DoWorkEventArgs e) { var slides = (IList<UIElement>)e.Argument; var bmpSlides = new List<UIElement>(); var imageService = new ImageService(); int count = 0; foreach (UIElement slide in slides) { object retVal = slide.Dispatcher.Invoke( new ThreadStart(() => imageService.GenerateProxyImage(slide))); bmpSlides.Add(imageService.GenerateProxyImage(slide)); _backgroundWorker

I have a dispatcher set up with a fairly deep stats file level due to a particular project in a multi tenancy situation. What I'm hoping is for a way to be able to recursively flush directories to mimic a more shallow stats file level for the other tenants. Is there a dispatcher flush command that allows me to explicitly delete a directory of content? You could achieve this yourself by sending a simple GET request to your dispatcher. The path on the Dispatcher that you need to hit is /dispatcher/invalidate.cache . The following headers ensure that it's processed correctly: CQ-Action: This can

Ok this may be really simple but everything I try just seems to hit a brick wall. I have a view model with two properties, which are bound to my WPF form: bool IsWorking {get;set;} ObservableCollection<OtherViewModel> PendingItems {get;set;} I have a method that I call to fetch some new pending items from outlook, however I also what to show some sort of progress on the form(spinning progress bar), the progress bar visibility is bound to the IsWorking property on the ViewModel, and a grid is bound to PendingItems collection. I would like to be able to set the IsWorking to true so the UI can
