wrapper

I would like to write a class library which creates for me a complex object but should only be exposed as little as possible. I want it to be included into other projects and there I only have one call to this library which e.g. returns me an object of a internally created class. I don't want to allow others to create these objects explicitly, but still I want to create a test project for this class library. For example: var result = Manager.Instance.Create(definition) This should be the only access to the class library. Based on the definition parameter it uses different sub classes to create

public class WrapperTest { public static void main(String[] args) { Integer i = 100; Integer j = 100; if(i == j) System.out.println("same"); else System.out.println("not same"); } } The above code gives the output of same when run, however if we change the value of i and j to 1000 the output changes to not same . As I'm preparing for SCJP, need to get the concept behind this clear. Can someone explain this behavior.Thanks. In Java, Integers between -128 and 127 (inclusive) are generally represented by the same Integer object instance. This is handled by the use of a inner class called

My web application currently has do execute simple queries: simple CRUD operations, counting,... A few months ago, someone recommended me here to write a simple PDO wrapper for this (to avoid writing try/catch, prepare(), execute(), etc. each time a query should be executed). This example method was shown (I've made some changes so I could use it in my own project): public function execute() { $args = func_get_args(); $query = array_shift($args); $result = false; try { $res = $this->pdo->prepare($query); $result = $res->execute($args); } catch (PDOException $e) { echo $e->getMessage(); }

/linkresource is a csc option that allows to link an assembly to its unmanaged dependencies. When the managed assembly is added to the GAC, the dependencies are placed in the same folder. This is how all the .NET wrappers should be installed... There is very little information on how to do this in Visual Studio. There is no official answer, just people that hacked a solution. For example http://www.netframeworkdev.com/msbuild/msbuild-linkresource-nonassembly-external-file-beforecompile-24358.shtml . This used to work on VS2008 but it looks like it doesn't work on VS2010... :-/ Does VS2010

I am playing with Swift and noticed that Swift does not allow to create CFFunctionPointers. It can only pass around and reference existing ones. As for example CoreAudio requires CFunctionPointer to certain callbacks therefore I cannot use pure Swift. So I need to use some Objective-C trampoline or wrapper here that takes a Swift Closure as a parameter as well as the original callback prototype and then can be assigned to be the callback, but the actually action happens in Swift and not Objective-C. How do I do this? Some example code for such a wrapper would help me to understand how I can

http://code.google.com/p/tesseractdotnet/ I am having a problem getting Tesseract to work in my Visual Studio 2010 projects. I have tried console and winforms and both have the same outcome. I have come across a dll by someone else who claims to have it working in VS2010 : http://code.google.com/p/tesseractdotnet/issues/detail?id=1 I am adding a reference to the dll which can be found in the attached to post 64 from the website above. Every time I build my project I get an AccessViolationException saying that an attempt was made to read or write protected memory. public void StartOCR() { const
