Hey guys!

I am newbie to this, I'm in need for help in my C++ project, I seem to be getting this error and have no idea why it keeps saying the same thing, i created header and cpp files but this error is annoying me:

projectnew.obj : error LNK2005: "class sqlform2 cmd" (?cmd@@$$Q3Vsqlform2@@A) already defined in form2.obj
C:\Users\abugslife\Desktop\backup - Copy (V4)\projectnew\Debug\projectnew.exe : fatal error LNK1169: one or more multiply defined symbols found


Any help would be much appreciated thanks!

Better show us the code..

You probably have the implementation of this class in two .cpp files

This is my .h file:

#ifndef __SQLFORM2_H__
#define __SQLFORM2_H__

#include "stdafx.h"


using namespace System::Data::SQLite;
using namespace System::Data;
using namespace System::Windows::Forms;

class sqlform2
{
public:

	void add(System::String ^ProductName, System::String ^Size, System::String ^Style, System::String ^Colour, System::String ^Price, System::String ^InStock, DataGridView ^dataGridView1);




private:
	
protected:
};

#endif

This is my .cpp file:

#include "stdafx.h"
#include "sqlform2.h"

using namespace System;
using namespace System::Data::SQLite;
using namespace System::Data;
using namespace System::Windows::Forms;

void sqlform2::add(System::String ^ProductName, System::String ^Size, System::String ^Style, System::String ^Colour, System::String ^Price, System::String ^InStock, System::Windows::Forms::DataGridView ^dataGridView1) {

//ive got my sql functions here//

this is my code for the function of adding data to my form for the above stuff:

private: System::Void button1_Click_1(System::Object^  sender, System::EventArgs^  e) {

			String^ ProductName = textBox1->Text;
			String^ Size = textBox2->Text;
			String^ Style = textBox4->Text;
			String^	Colour = textBox5->Text;
			String^	Price = textBox6->Text;
			String^	InStock = textBox11->Text;

			cmd.add(ProductName, Size, Style, Colour, Price, InStock, dataGridView1);
			
		 }
};

This is the code for same form of the above code but the top part

#pragma once

#include "sqlform2.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;
using namespace System::Data::SQLite;

	sqlform2 cmd;

namespace projectnew {

thanks for checking!
