on button click create new window and display content of array c# (csharp)

Thanks a million. I just need to change the str to incorporate my array which is string[,] myarray = new string[1,12]

:)

You don't need to make the listbox public
Look here

The second Form

-----------------------------------


using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;

namespace MyProject
{
public partial class Form2 : Form
{

public static Form2 Fm2 = null;

public string[,] secondArray = null;

public Form2()
{
InitializeComponent();
}






public void Form2_Load(object sender, EventArgs e)
{
Fm2 = this;

}

private void button1_Click(object sender, EventArgs e)
{

this.Hide();

}

private void listBox1_SelectedIndexChanged(object sender, EventArgs e)
{

}
}
}

Hi, Ok so I can access the second form, but I need to show the data in a list box. I have entered my code below.

I need to access the array tradebuilder and put the data into a listbox which is displayed in Form2.

Any Ideas?


-----------------------------
Form1

namespace MyProject
{
public partial class Form1 : Form
{
//#################################
//GLOBAL variables

string isin;
string kv;
string price;
string tdate;
string sdate;
string tdID;
string tradeID;

int kv_number;
int trade_number=0;

double Price;

//##################################
//GLOBAL ARRAY

public string[,] tradebuilder = new string[1, 12];



//##################################
//##################################
//##################################

public void ResizeArray(ref string[,] original, int cols, int rows)
{
//create a new 2 dimensional array with
//the size we want
string[,] newArray = new string[rows, cols];
//copy the contents of the old array to the new one
Array.Copy(original, newArray, original.Length);
//set the original to the new array
original = newArray;
}

public static Form1 Fm1 = null;


public Form1()
{
InitializeComponent();

string[] stocknames = File.ReadAllLines("StockNameDE.txt");

foreach (var line in stocknames)
{
string[] tokens = line.Split('\n');
comboBox2.Items.Add(tokens[0]);
}

}

//Initialising area for date
