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

Question

I have a issue I cannot get my head around.

I have a main GUI in where I add data, 12 columns. Each data on 1 row as it comes in. This data is pushed into a array which is accessible globally. the array is dynamic 2D, growing each time I enter a set of data.

I wish to have a button that when pressed displays all the currently available data held in the array. If I can edit it then its a step further but at the minute I just need to be able to view the contents of my array.

My code is long as there are many buttons, listboxes doing different things. If any one has an idea I can mail them my code.

Thanks, Timunjin

Thanks a million. I just need to change the str to incorporate my array which is string[] myarray = new string[112] :)

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

Thanks Frogleg. I have made the listbox public now I need to figure out how to pass the 2D array to the listbox

Put a public method on Form2 that loads the listbox which you can then access from Form1

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('
