So this is a purely academic question, mostly as its been a while since I've done anything too complex in C++. But is there any way to know if a method is taking a paramter as a reference or a value? This isn't important for pointers, as if you try to pass a non-pointer to a method that takes a pointer, you get a compile error. But somet...

I'm an experienced coder, but am still relatively new to the STL, and have just come across this problem: As far as I'm aware, STL containers aren't meant to copy the objects which they contain, or otherwise affect their lifecycles, yet experimentally I'm seeing different results. In particular, string classes, which are meant to zero ...

Model, Controller and Presenter are reference to each other as the MVC pattern and UI will reference the Controller. How can I display the data to UI which...
Hi, I'm using .NET 4, trying to add a reference to mshtml, and I want to have all the capabilities depending on the version the client has installed. If I add a reference to the COM component called 'Microsoft HTML Object Library', the reference is labelled "MSHTML" and the path points to an assembly in the GAC called 'Microsoft.html' ...
Why aren't C1 and c2 have the same hashcode ? the code doesn't get to "Same".... ( i=0 in both classes) class myclass { public static int i; static void Main() { myclass c1 = new myclass(); myclass c2 = new myclass(); if (c1.GetHashCode() == c2.GetHashCode()) Console.Write("Same"); ...
We have a Visual Studio 2010 solution that contains several C# projects in accordance with Jeffery Palermo's Onion Architecture pattern (http://jeffreypalermo.com/blog/the-onion-architecture-part-1/). We have a UI project that is an ASP.Net MVC project, and we have a C# Class Library project called Infrastructure that is referenced by t...

I have just started python and came across something kind of strange. The following code assigns a co-ordinate of x=1 and y=2 to the variable test. The test2 variable assigns itself the same value as test and then the [x] value for test2 is changed to the old [x] value minus 1. This works fine, however, when the last part is executed, n...

why the referenced dll of a c# project is in full path? when i move the source code to a different pc, the reference is broken. ...
Hi there, I have got the array containing some data, say, a header and a real data. I need to pass the data contained in the array to a method, but I definitely want to avoid copying it to another array. I thought of something like ArraySegment, but it seems not to work in my case (or maybe I'm wrong?). So, how to pass a part of an a...
Hi there, here is the situation: I want to call a method from a C++ module, and pass an array to it: x.Method(array, ...) x is a C# object. I would suppose that I could change the array and fill it with my own data - but it seems not be the case (?) How should I pass the array by reference and change its content in the method? Tha...
To begin with, I understand programming and objects, but the following doesn't make much sense to me in PHP. In PHP we use the & operator to retrieve a reference to a variable. I understand a reference as being a way to refer to the same 'thing' with a different variable. If I say for example $b = 1; $a =& $b; $a = 3; echo $b; will...
Hi, I get an Error "HRESULT E_FAIL has been returned from a call to a COM component" when adding a .dll reference to a project in Visual Studio 2010. The weird thing is, if I make a local copy of the .dll, and reference it locally it's fine. However, if I try and reference it from our shared resources server (\server\release\Common\Pa...
I fail to understand is why does the code print '3' in VS2010 (release build), whether I leave the declaration of 'r' or comment it out. int main(){ int arr1[2]; int &r = arr1[0]; int arr2[2]; cout << (&arr1[1] - &arr2[0]); } So, three questions: a. why does the code print 3? b. why does it print 3 even if the decla...
