I want to use Vectors in a C# application I'm writing, sepcifically a Vector3.
What's the best way for me to get a Vector type without writing my own?

I’ve run into the problem a few times now: How to pre-authenticate .NET WebRequest calls doing an HTTP call to the server – essentially send authentication credentials on the very first request instead of waiting for a server challenge first? At first glance this sound like it should be easy:…

Man I can't believe this. I'm still mucking around with OFX servers and it drives me absolutely crazy how some these servers are just so unbelievably misconfigured. I've recently hit three different 3 major brokerages which fail HTTP validation with bad or corrupt certificates at least according to…

The dynamic type in C# 4.0 is a welcome addition to the language. One thing I’ve been doing a lot with it is to remove explicit Reflection code that’s often necessary when you ‘dynamically’ need to walk and object hierarchy. In the past I’ve had a number of ReflectionUtils that used string based expressions…

I’ve written quite a bit about Visual FoxPro interoperating with .NET in the past both for ASP.NET interacting with Visual FoxPro COM objects as well as Visual FoxPro calling into .NET code via COM Interop. COM Interop with Visual FoxPro has a number of problems but one of them at least got a lot…

Here’s a nice and simple path utility that I’ve needed in a number of applications: I need to find a relative path based on a base path. So if I’m working in a folder called c:\temp\templates\ and I want to find a relative path for c:\temp\templates\subdir\test.txt I want to receive back subdir\test…

Hi,
I have this destructor that create error at runtime "vector iterator not dereferencable".
The gridMatrix is a std::vector<std::vector<std::vector<AtomsCell< Atom<T> * > * > * > * >
I added the typename and also the typedef but I still have the error.
I will move…

I have this implementation of vector that I've been working on for a few days using examples from a textbook:
#include <iostream>
#include <string>
#include <cassert>
#include <algorithm>
#include <cstring>
// Vector.h
using namespace std;
template <class T>
class…

I want to create a vector<vector<int>> where the outer vector is fixed (always containing the same vectors), but the inner vectors can be changed. For example:
int n = 2; //decided at runtime
assert(n>0);
vector<vector<int>> outer(n); //outer vector contains n empty vectors
outer…

That's x \ y using mathematical notation. Suppose
x <- c(0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,1,1,2,1,1,1,3)
y <- c(0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,1,1,1)
How can I get a vector with ALL the values in x that are not in y. i.e the result should be:
2,1,1,3
There is a similar question here…

Assuming I have 2 STL vectors:
vector<int> a;
vector<int> b;
Let's also say the both have around 30 elements.
How do I add the vector b to the end of vector a?
The dirty way would be iterating through b and adding each element via push_back, though I wouldn't like to do that!
