I'm wondering what happens when I use a MKReverseGeocoderDelegate in my ViewController, but the application is running in 2.2.1. Because I'm supporting 2.2.1 but using 3.0 as Base SDK. I have already added the framework as soft linking to support working on 2.2.1 and I understand I have to prepare the code to check if the MKReverseGeoco...
In C#, is it possible to have an object that has multiple method signatures for an Action<> or delegate? Like this: class Foo { public Action<string> DoSomething; public Action<string, string> DoSomething; } class Bar { public Bar() { Foo f1 = new Foo(); f1.DoSomething = (s) => { Console.Write(s) }; ...
See Also: understanding events and event handlers in C# As a web dev, I don't typically have to get into building my own events for objects, since most are inherent in the page. However, now I'm into a pretty complex (web) project where I think I may have to use them. I just read a chapter out of Pro VB 2008 and the .NET 3.5 Pl...
In C#, you can define small pieces of code called delegates anonymously (even though they are nothing more than syntactic sugar). So, or example, I can do this: public string DoSomething(Func<string, string> someDelegate) { // Do something involving someDelegate(string s) } DoSomething(delegate(string s){ return s += "asd"; }); D...
I'm trying to implement the shake "tutorial" on this page, but I think I'm missing something. I copied his accelerometer function into myAppViewController.m file and put some nslogs in there to see if it even gets into the function when I use the simulators "shake" function. Nothing shows up in the debug console. http://mithin.in/2009...
I am using a variable/propery of my application delegate as a global. (I don't want to deal with a singleton class.) I am trying to write a #define statement in my Application Delegate class. If I type: [UIApplication sharedApplication] in my app delegate class, code hinting does not recognize sharedApplication. But if I type th...

Out of habit I tend to put classes/structs/enumerations in separate files when not nested. For delegates, it seems like overkill to create a seperate file for a one liner: public delegate string MyDelegateThatIsNotNestedInAnyClass ( string par ); I usually add it to the bottom of the most closely related class file. I was just wonde...
After reading Dynamically calling unmanaged dlls in .net I've been trying to modify the code to my liking. I made a class that implements idisposable to wrap load calls in and free them when needed. However I can't seem to figure out the syntax if it is possible to use anonymous delegates with it. var loaded=DynamicLibraryLoader.TryLo...
I currently have this: instance = new Class1<Type1>( "param1", () => new ViewDataDictionary<Type2>( new Class2 { Prop1= CreateList(new List<long> { 234 }), Prop2= CreateList(new long[] { 234 }) ...
Say if I listen for an event: Subject.NewEvent += delegate(object sender, NewEventArgs e) { //some code }); Now how do I un-register this event? Or just allow the memory to leak? ...
I know a good bit of Objective-C and I'm working on a iPhone SDK book (coming from a Obj-C book that just did console programs). It attempted to explain delegates though it was rushed and didn't really understand what it was trying to convey. I'm a little confused on what they are and when you would use them. Basically it said they ar...
Hi! I'm trying to get the following thing done: public delegate void SomeMethod(params object[] parameters); That's my delegate. And i have some method that will run this SomeMethod delegate (whatever's passed) and return me the timespan of execution. public TimeSpan BenchmarkMethod(SomeMethod someMethod, params object[] paramete...
Is there a way to disable the standard built-in function of the Windows-Key (open the start-menu) and activate instead of that function for instance a delegate or an event in C#? I want to use this as an additional key in a full-screen app. ...
Hai Techies, in C#, how can we define the multicast delegate which accepts a DateTime object and return a boolean. Thanks ...
I've created a new class that inherits from SortedDictionary: public partial class ListIncomeWeight : SortedDictionary<string, double> { public Guid Identity { get; set; } } This list is combined with a few dozens of other lists, where the other lists will keep track if they already calculated with this list or not. For that purp...
I have a page Product.aspx,there I have a user control ProductDisplay.ascx which has been created by drag and drop. Now when a button is clicked in ProductDisplay.ascx,I want a logging function to be called which is in Product.aspx. To achieve this I have used delegates on ProductDisplay.ascx public delegate void LogUserActivity(Prod...

In C# adding event handler methods is very easy. You just type "object.event +=" and then press tab twice. Is there anything like this for VB projects? Note: This is for dynamically created controls or controls that are not declared WithEvents. ...
