anonymous

I'm having some trouble with figuring out a way of unsubscribing from some anonymous delegate events that i found in a pre-made helper file that helps allow movement of controls at run time. The reason i want to unsubscribe to these events is so that the control (in this case buttons) will become locked again and not able to be moved. Here is the method in the helper class: public static void Init(Control control) { Init(control, Direction.Any); } public static void Init(Control control, Direction direction) { Init(control, control, direction); } public static void Init(Control control,

When should anonymous methods be used when defining a delegate and when should formally defined methods be used when defining a delegate ? If you need to use the same logic in more than one place, it makes sense to use a separate method. If you only need to use the logic once and it's fairly short, it makes sense to use an anonymous function. If the delegate needs access to local variables in the method which is creating it, anonymous functions act as closures which can also be very handy. Additionally, an anonymous function can be useful even if it's reasonably long if it's used for something

I am a beginning javascript programmer. I am trying to create something similar to Lightbox 2, but much simpler. The only reason why I want to do it from scratch on my own is so that I can learn. However, I've been stuck on the last critical part where it displays the image. I believe the problem lies where I try to use onclick with assignment to an anonymous function: elem[i].onclick = function (){liteBoxFocus(imgSource,imgTitle); return false;}; . If you run my code and try clicking on the google logo it'll bring up the yahoo logo and title instead of google's logo and title. However when

I need an idea to create anonymous class on PHP. I don't know how I can works. See my limitations : On PHP you can't make anonymous class, like anonymous function (like class {} ); On PHP you don't have class scope (except in namespaces, but it have the same problem below); On PHP you can't use variables to specify the class name (like class $name {} ); I don't have access to install the runkit PECL. What I need, and why : Well, I need create a function called ie create_class() that receives a key name and a anonymous class . It'll be useful for me because I want use different name class

Is this allowed? : class A; void foo() { static A(); } I get signal 11 when I try to do it, but the following works fine: class A; void foo() { static A a; } Thank you. Nope. There is no such thing as an "anonymous object" in C++. There is such a thing as defining an object to type A that is immediately discarded; what you've written is an expression that returns an A object that's never assigned to a variable, like the return code of printf usually is never assigned or used. In that code, if it worked, you'd be declaring "no object" to be allocated outside the heap. Since there's no object to

In Xcode and Instruments I see UILabel (CALayer) using large amounts of virtual memory (Anonymous VM). I see about 235 KB of virtual memory per UILabel . I think this perhaps is a new issue with iOS 7.1 or 7.1.1. Is this expected? I created a simple program that creates 500 UILabels and Instruments shows 115MB of memory used. At about 1500 labels the application is terminated by the OS. for (int i = 0; i < 500; i++) { index = (int)[self.items count]; index++; frame = CGRectMake(10.0, 20, 300.0, 50.0); UILabel *newLabel = [[UILabel alloc] initWithFrame:frame]; newLabel.text = [NSString
