Need Help With System String^ variable

etow · October 10th, 2008, 12:00 PM

Hi,

How do you make a System String^ variable called results, for example, declared in the namespace class of Form1 of the Windows Form Application, to be made globally accessible to a .H Header file that contains unmanaged code? I need to access a textbox text field of the main namespace class Form1 of Windows Form Application from a .H Header file in order to print out the text results from the System String^ variable called results to a textbox in the namespace class of main Form1 in the Windows Form Application. I know how to output the System String^ to a textbox from the Form1 but not sure how to get .H form to do it?

I was wondering how can you do this?

Please help.

Thanks

In your GlobalVariables.h file:

Code:

#include "stdafx.h"

#ifndef GLOBALVARIABLES_H
#define GLOBALVARIABLES_H

public ref class GlobalVariables
{
  public:
    static System::String^ display; 
};

#endif

-----------------------------------

Code:

In your stdafx.h file:

#pragma once
#include <stdio.h>
#include <stdlib.h>
#include <string>
#include "GlobalVariables.h"
using namespace System;
using namespace System::ComponentModel;
using namespace System::Collections;
using namespace System::Windows::Forms;
using namespace System::Data;
using namespace System::Drawing;

-----------------------------------------------

To use the global string in your code by referencing like this:

GlobalVariables:: display = GlobalVariables:: display + "a string";

or:

GlobalVariables:: display += "a string";
