Insert commas to textbox

Thanks Jon Montano for ur post but can i have the second problem being solved i.e the value say 1,23,45,677.00 in the text box to be multiplied with 0.12 which is giving value 0 for me.

using System.Globalization;
using System.Threading;

// insert two textboxes in your form: textBox1 & textBox2

private void Form1_Load(object sender, EventArgs e)
        {
            //Test1();
            Thread.CurrentThread.CurrentCulture = new CultureInfo("hi-IN");
            this.textBox1.TextChanged += new System.EventHandler(this.textBox1_TextChanged);
        }

        private void textBox1_TextChanged(object sender, EventArgs e)
        {
            textBox2.Text = string.Format("{0:C}", Convert.ToDouble(textBox1.Text));
        }

You'll notice that if you input numbers in textbox1, currency in indian format will be displayed on textbox2. To be able to display in the format you want. you must set or you must initialize a cultureinfo first.



*EDIT: oops this one is in c#. Please modify as you wish. The important thing here is the cultureinfo. goodluck.
