How should defined class where are only global variables? I did something like that:
public ref class Klient
{
public:
Klient(){}
// zmienne
static array<DWORD,2>^ klienty = gcnew array<DWORD,2>(40,2);
static int i = 0;
static DWORD pid;
static HANDLE handle;
static String^ nick;
//funkcje
};
But if i include it more than 1 time it won't compile and showing redefinition of class error.
Did you guard your header? In Visual Studio, you should place this directive at the top of all header files:
#pragma once
This is equivalent to the classic C++ header guard:
#ifndef HEADER_SYMBOL_X
#define HEADER_SYMBOL_X
// class declarations go here
#endif // HEADER_SYMBOL_X
If you don't guard your header, C++/CLI will indeed try to redefine your class on each include.
You'll have to be a little more clear, and paste the error you get. Also if you have a "ref" class the compiler generates a default constructor for you, so you don't need to write one.
This code worked for me, I was able to fetch the static int value into my WPF application:
#pragma once
#include "windows.h"
using namespace System;
namespace cppcli
{
public ref class Klient
{
public:
static array<DWORD,2>^ klienty = gcnew array<DWORD,2>(40,2);
static int i = 22;
static DWORD pid;
static HANDLE handle;
static String^ nick;
};
}
Update:
Noticed your comment, yes you need #pragma once
in there. I assumed it was there since it's generated automatically by Visual Studio, well good to know that it works :-)
