I'm using Remoting to perform some IPC communication, and have the following question: When I invoke delegates to gather data server-side, it is possible to have an event fired on the client when an IAsyncResult is gathered?

With multi-tasking in iOS4, the home button puts the app into background and when it comes back into foreground I want the View Controller to 'refresh' (and hence viewWillAppear to be called). I put this in the app delegate thought this should work but nothing happens - (void)applicationDidFinishLaunching:(UIApplication *)application {...

I'm trying to make a class to handle invoking methods on a remote server using my own means. To make it easier on the client caller, I'm writing a generic class that accepts an interface so that the compiler will know the number of arguments and the return type of the method. public class Service<TInterface> { public TResult Invoke<...
I may just be passing data between views completely wrong here, so I am open to completely changing how I pass my data back and forth. My app delegate creates the NSManagedObjectContext and passes that to my main menu using a UINavigationController which makes it the root view: MainMenuViewController *mainMenuViewController = [[MainMen...
I would have expected delegates generated from expression trees to achieve roughly the same performance as hard-coded, static, equivalent anonymous methods. However, it seems that dynamically generated delegates are noticeably slower... Here's a simple test program to illustrate the case. It just accesses 3 properties of an object 10000...

Hi, I came across a code which was using BeginInvoke to update label text in a certain way, which I found strange and I can't understand why would somebody do that. If I want to use threading to allow good user experience, I would create a thread and update the labels in the new thread using Thread.Start nethod. Why would I use the b...
I'm currently using BeginInvoke(with ASyncCallback) to handle my Client\Server communications with remoting. Here is my current setup: ... //Main Remoter.StationDelegate svd = new Remoter.StationDelegate(IPCObjectInstance, &Remoter.GetStationInformation); AsyncCallback callback = new AsyncCallback(this, &CentralControlClient.Sta...
I have 2 classes whose object should act as "partners". The first one is my Thing class, whose instances should act as Tree::TreeNodes of the gem RubyTree.
