Say I have the following C# code: Action a = TestMethod; Action b = TestMethod; Action c = b; b += a; Tests indicates that b is not the same instance as c, so clearly the + operator seems to create a new instance of the delegate. Is this a correct assumption? Does it reuse the b-instance internally, or does it just copy the method/tar...
Hi Guys, I have problem creating new instance of excel 2007 using VBA (from Access 2002). At first I misunderstood the problem and it is more complicated than I thought. Set myXL = CreateObject("Excel.Application") Creates new processes (I thought it didn't), but still strange thing is happening. I use OLE to store Excel files in SQ...
I need a class that works like this: >>> a=Foo() >>> b=Foo() >>> c=Foo() >>> c.i 3 Here is my try: class Foo(object): i = 0 def __init__(self): Foo.i += 1 It works as required, but I wonder if there is a more pythonic way to do it. ...

I have webRole with some data stored in Session. The data is some tens of small variables (strings), and one-two big objects (some megabytes). I need to run this webRole in multiple instances. Since two requests from the single user can go to different instances, Session became useless. So, i am looking for most efficient and simplest me...

Ok so here's my code, it works great: - (void)textViewDidChange:(UITextView *)textView{ if (textView==someObject) { [detailItem setValue:textView.text forKey:@"someObjectAttribute"]; } The problem is that I have lots of textviews instances to test for and I would prefer to find some other way to consolidate the code. I was thinkin...
Ok, this, I'm sure is something simple that is easy to do. The problem : I've inherited scary spaghetti code and am slowly trying to better it when new features need adding - generally when a refactor makes adding the new feature neater. I've got a bunch of code I'm packing into a single unit which, in different places in the appli...

Hello, I am new to Python and this is my first time asking a stackOverflow question, but a long time reader. I am working on a simple card based game but am having trouble managing instances of my Hand class. If you look below you can see that the hand class is a simple container for cards(which are just int values) and each Player c...
The ec2-describe-instances command is not very helpful in distinguishing the instances. Are there command line tools that give a better overview? Perhaps somewhat like http://github.com/newbamboo/manec2 but with support for different regions etc. ...
Hi, We have a WAMP server. We have to deliver it to the client and ensure that only one instance of the server can be used. We are looking for a simple protection(since any scheme can be broken). Basically, we want to limit the number of server installs to 1. Please let me know a solution that can be implemented in a short time. Thanks...

Exercise 14.16-17 in Thompson asks me to add the operations of multiplication and (integer) division to the type Expr, which represents a simple language for arithmetic, then define the functions show and eval (evaluates an expression of type Expr) for Expr. My solution works for each arithmetic operation except division: data Expr = L...
So, say I had the following script: var hey = { foo: 1, bar: 2, baz: 3, init: function(newFoo){ this.foo = newFoo; return this; } } hey.check = function(){ alert('yeah, new function'); } Basically, I can call new hey.init(999) and get a new hey variable with hey.foo set to 999. But when I do tha...
