Hi, Good practice is to include into source repository all 3rd party assemblies required by sources to compile. Then reference such assembies from within repository. The problem is, sometimes license of referenced assembly directly prohibits such action, eg: "You can not publish the software for others to copy" - this covers any kind of...
Hi there, I'm currently in the process of researching the best development and deployment practices for our team. We have a load of similar code that we're going to start importing into a library of shared assemblies for use across our suite of (web & win) applications. I'm starting to get a clear idea of where I think we should be he...
Perhaps I am missing something obvious here but... I have built a reusable generic C# class library project say (A.dll) which references 3 other assemblies say (B.dll, C.dll and D.dll) However if I want to reuse my component A.dll in another project I still have to include the references to B.dll, C.dll and D.dll. Is there any way you...
I thought I had references in AS3 figured out, but the following behavior puzzles me: // declarations for named individual reference later on var myAmbientSound:Sound; var myAmbientSoundLocation:String = "http://ambient_sound_location"; var myPeriodicSound:Sound; var myPeriodicSoundLocation:String = "http://periodic_sound_location"; v...

Hello, I was toying (read: learning) around with Javascript and came across something to my understanding, seems very odd. It has to do with closures and a reference that seems to 'loose' its importance to the browser. The browser I am using is Chromium 5.0.307.7. Anyway, here's some code: HTMLElement.prototype.writeInSteps = function...
Hi, Can anybody explain to me why there is a difference between these two statements? class A{}; const A& a = A(); // correct A& b = A(); // wrong It says invalid initialization of non-const reference of type A& from a temporary of type A Why does const matter here? ...
Say I had something like: # %superhash is some predefined hash with more than 0 keys; %hash = (); foreach my $key (keys %superhash){ $superhash{ $key } = %hash; %hash = (); } Would all the keys of superhash point to the same empty hash accessed by %hash or would they be different empty hashes? If not, how can I make sure they...
I noticed that there is no reference to reference but there is pointer to pointer, and also there is no an array of references but an array of pointers. Could anybody give me any reason? ...
I'm just learning c++, and coming from c, some function calls I'm seeing in the book confuse me: char a; cin.get(a); In C, this couldn't possibly work, if you did that, there would be no way to get the output, because you are passing by value, and not by reference, why does this work in c++? Is referencing and dereferncing made implic...
