Usually like this: #include <boost/assign/std/vector.hpp> vector<int> v; v += 1,2,3,4,5; Except for a: #include <boost/ptr_container/ptr_vector.hpp> boost::ptr_vector<int> v; If you need to know the reason; I'm using ptr_vector instead of vector only so I don't have to delete elements, but I need to initialize it using Boost.Assign...
Hi, I have in my header "Test.h" a variable of a class that doesn't have a constructor without arguments. And I have a constructor like this: Test::Test() // <-- Here he complains: // error: no matching function for call to ‘Beer::Beer()’ { int i = 2; theVar = Beer(1, i); // Beer(int, int) is the only constructor } ...

In my Html, I have written: <param name="InitParameters" value="UserId=1" /> In code I am reading the parameters in: foreach (KeyValuePair<string, string> pair in e.InitParams) { Resources.Add(pair.Key, pair.Value); } e.InitParams is always empty. Any ideas? ...
I have read that there are good reasons to use properties instead of fields in c# on SO. So now I want to convert my code from using fields to using properties. For an instance field of a class, I can set a default value. For example: int speed = 100; For the equivalent property, which I think is: int Speed { get; set; } My unders...
I am so used to work in PHP with multi-dimensional arrays, where I can assign and initialize a hash by unset($a); // just to show that there is no variable $a $a['settings']['system']['memory'] = '1 Gb'; $a['settings']['system']['disk space'] = '100 Gb'; Is there a way to do similar thing in Ruby? Or I need to initialize all dimension...
Hi all - Using a Python array, I can initialize a 32,487,834 integer array (found in a file HR.DAT) using the following (not perfectly Pythonic, of course) commands: F = open('HR.DAT','rb') HR = array('I',F.read()) F.close() I need to do the same in ctypes. So far the best I have is: HR = c_int * 32487834 I'm not sure how to initi...

Hi, I am creating a software project in which most business objects are stored in files (in a legacy format). The objects will only be instantiated from an inputstream. I do this today with making the constructor private and instantiating in a static function as follows: public class BusinessObject { private BusinessObject() {} ...

I would like to initialize several auto-vivifying hashes by one-line expression. So far I came to an extra method for the AutoHash object: class AutoHash < Hash ... def few(n=0) Array.new(n) { AutoHash.new } end which allows me to do the following a, b, c = AutoHash.new.few 3 However, I feel that one can make the followin...
I am trying to block access to the default constructor of a class I am writing. The constructor I want others to use requires a const reference to another object. I have made the default constructor private to prevent others from using it. I am getting a compiler error for the default constructor because the const reference member var...
How do you deal with them? I have some classes (usually classes that hold stats etc.) with some 20+ variable members, and the initialization lists end up very long, extending beyond the page width if I don't manually wrap around. Do you try and break down such classes or do you deal with this in some other way? It doesn't look very tid...

I need to assign some strings inside an if structure but use them outside the if structure so they need to be created outside the if, I was thinking something like: NSSt...
