struct with classes

[jorz]

Hi all,

I would like to use a struct in c++ with classes

I use visual studio

it does not allow me to define it within the current class

my visual studio files

Form1.h this is where my button function is.

label writer.cpp this is where main is.

I would like to access the same struct and data from different classes is this possible.

I can define and declare a struct in label writer.cpp and access it from there but I would like to access the data from Form1.h how can I do this.

I have watched some video's but it is still not clear.

please help.

Kind regards,

Jorz

Can you give an example of what you are trying to do that isn't working?

[Stewbond]

Something like this?

struct Point {
  int x;
  int y;
  int z;
};

struct Vect3D {
  int x;
  int y;
  int x;
};

class Plane {
private:
  Vect3D v;
  Point p;
public:
  // Do stuff with these structs here  
};

I can do that Stewbond in my cpp file but the issue is I need to access them in .hpp file this is where my button stuff is done.

.cpp file
#include "stdafx.h"
#include "Form1.h"

using namespace Labelwriter;



// EbayData EBAYDATA1;




[STAThreadAttribute]
int main(array<System::String ^> ^args)
{


// Enabling Windows XP visual effects before any controls are created
Application::EnableVisualStyles();
Application::SetCompatibleTextRenderingDefault(false);

// Create the main window and run it
Application::Run(gcnew Form1());
return 0;
}

and my Form1.h file

#pragma once

Does anyone know how to do this?
