I've seen several Scala questions recently (e.g. here, here, and here) that called for the use of proxies, and it's come up more than once in my own work. The Scala library has a number of proxy traits (14, if I counted correctly). Proxy classes/traits usually contain lots of boilerplate: class FooProxy(val self: Foo) extends Foo { ...

Is there any way to get a delegate to run on a specific thread? Say I have: CustomDelegate del = someObject.someFunction; Thread dedicatedThread = ThreadList[x]; Can I have a consistent background long running thread and invoke my own delegates on it whenever I need it. It has to be the same thread each time. [Edit] The reason why...
Hi I'm getting a warning when I set the delegate for UIImagePickerController. It's because UIImagePickerController and its parent UINavigationController both have delegates that can be used. The code works fine but just wondering how to handle delegates and inheritance properly and lose the warning. So basically I've created my own MyI...

Okay, I understand how to work delegation in a modal view to send a message to the parentviewcontroller but what if I wanted to do that with 2 views that dont have that parent-child relationship? I have a navigation controller that flips over a modal view and then that modal view pushes a new view controller. How do I let that pushed vi...
This is my first question on SO, so if it seems beyond dumb, please take it easy on me. I have a page with a list of pictures with links for deletion underneath them and with possibility to add more pictures.

I'm attempting to re-organize my application's namespace hierarchy, so I'm using a System.Runtime.Serialization.SerializationBinder sub-class to attempt to handle the renaming. (Most of my renamed classes are correctly deserialized into their new namespaces without problems.) The problem I have is that one of my serialized classes (whi...
From Silverlight 4, it's pretty easy to start Word and let the user do something: dynamic word = System.Runtime.InteropServices.Automation.CreateObject("Word.Application"); word.Visible = true; word.Documents.Open("test.doc"); MS Word exposes a Quit event[1]. I'd like to handle this event, but for the life of me I can't figure out how...

Edit: Problem is solved by updating. Resharper is really annoying me and marking code that is 100% correct as wrong, it keeps wanting me to change an Action to an Action<T1,T2...Tn> when this obviously incorrect. It flashes everytime I type something so is really distracting. Is there a way to disable resharper totally inbetween two c...
How can I create a new file containing just it's own delegate so that I can make an ASIHTTPRequest with its own asynchronous ending, and something easy enough where I just need to set [request setDelegate:self]; to something like [request setDelegate:AlternateDelegate]; and just add an include at the begining of the document to reference...

Hi. I have a bunch of connection related methods that I need to execute before the table is actually being populated (before any of the delegate methods for a UITableView are called). The connection methods will add objects in a NSMutableArray that will later be used to populate the table view. Is there a way to tell the iPhone to wait...
