Re: Function in header file - newbie VC++/CLI

Now I show code where I try use header file function.h

/// function.h

#pragma once

void Status (System::String ^message)

{

this->richTextBox1->AppendText(message+"\n");

this->richTextBox1->ScrollToCaret(); }

Code for Form1.h is the same but without declaration Status function and add
#include function.h :

// Form1.h

#include "function.h"

#pragma once

namespace header {

using namespace System;

using namespace System::ComponentModel;

using namespace System::Collections;

using namespace System::Windows::Forms;

using namespace System::Data;

using namespace System::Drawing;
