How to use arguments?

Question

Hi,

I have two file generated in visual studio c++ 2010 express.

test2.cpp

// test2.cpp : main project file.

#include "stdafx.h"
#include "Form1.h"

using namespace test2;

[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 Form1.h

#pragma once

namespace test2 {

using namespace System;
using namespace System::ComponentModel;
using namespace System::Collections;
using namespace System::Windows::Forms;

How to using argument from command prompt? For example how change

this->timer1->Interval = 10000;

on user var? Something like

this->timer1->Interval = time;

You can get a string array containing the command-line arguments by calling Environment::GetCommandLineArgs.
