Declaration of office

[Lubaaa]

I have a function in the header Form1.h calling from Motory.cpp.
But not me refer to it.
Do you know what toje?

Declaration:
Motory.cp :
#pragma warning(disable : 4996) // Disable warnings about some functions in VS 2005
#define WIN32_LEAN_AND_MEAN // Exclude rarely-used stuff from Windows headers

#include "stdafx.h"

#include <stdio.h>
#include <tchar.h>
#include <conio.h>
#include <process.h>
#include "USMCDLL.h"
#include "Form1.h"

using namespace System;
using namespace System::Runtime::InteropServices;
using namespace System::Windows::Forms;
using namespace Motory_2;

void zapisListBox1(DWORD,char*,char*);
//-----------------------------------------------------

void PrintDevices(USMC_Devices &DVS)
{
for(DWORD i = 0; i < DVS.NOD; i++)
{
zapisListBox1(i, DVS.Serial[i], DVS.Version[i]);
}
}


Declaration Form1.h :

void zapisListBox1(DWORD i, char* Serial, char* Version)
{
this->listBox1->Items->Add("Device - "+(i+1)+",\tSerial Number - "+Convert::ToString(Serial)+",\tVersion - "+Convert::ToString(Version));
}


Error:

Thank you for your help!!

zapisListBox1 is Form1 class method, and not global function. You need to call it having Form1 instance reference.

You mean like this? but it throws me an error too.

Form1::zapisListBox1(i, DVS.Serial[i], DVS.Version[i]);


error:

.\Motory_2.cpp(53) : error C3767: 'Motory_2::Form1::zapisListBox1': candidate function(s) not accessible

No, you need Form1 instance for this. It looks like you started to work with C++/CLI without C++ experience. I suggest you to learn C++ first.

In Motory.cpp you need to have variable of type Form1^, which must be initialized to existing Form1 reference. Having this reference, you can call class methods. I cannot show exactly how to do this, because I don't know your program structure.

How do I create a global pointer to Form1, which provide access to its methods?

I tried: public: System:: Windows:: Forms:: Form ^ Fun;

To Alex F Thank you very much... This problem is sort out.
