Dear Mahesh,
thanks for a good web about C#.

I have a question in "Visual C# " and wonder if you may help me.

I would like to load a bit map and store the positions of the cursor by moving the cursor over a line, into a matrix and have an out put of those cursor position as a TEXT file. how can I do that in C#?

thanks alot

this is the data file I was using...

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;
using System.IO;

namespace WindowsFormsApplication4
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private void Form1_Load(object sender, EventArgs e)
        {
            oBuilder = new StringBuilder();
            this.MouseMove += new MouseEventHandler(Form1_MouseMove);
        }
        StringBuilder oBuilder;
        private void Form1_MouseMove(object sender, MouseEventArgs e)
        {
            textBox1.Text = e.X.ToString();
            textBox2.Text = e.Y.ToString();
            oBuilder.AppendLine("X: " + textBox1.Text + " Y: " + textBox2.Text);
        }
        StreamWriter oWriter;
        private void Form1_FormClosing(object sender, FormClosingEventArgs e)
        {
            string ContentFile = oBuilder.ToString();
            SaveFileDialog oSDLg = new SaveFileDialog();
            oSDLg.Filter = "(*.txt)|*.txt";
            if (oSDLg.ShowDialog() == DialogResult.OK)
            {
                oWriter = new StreamWriter(oSDLg.FileName);
                oWriter.Write(ContentFile);
                oWriter.Flush();
            }
            oWriter.Close();
        }

    }
}

Ok, Let's try this solution

first, add those namespaces

using System.Text;
using System.IO;

add two textboxes into your form
then copy and paste this code in the code editor:
private void Form1_Load(object sender, EventArgs e)
        {
            oBuilder = new StringBuilder();
            this.MouseMove+=new MouseEventHandler(Form1_MouseMove);
        }
        StringBuilder oBuilder;
        private void Form1_MouseMove(object sender, MouseEventArgs e)
        {
            textBox1.Text = e.X.ToString();
            textBox2.Text = e.Y.ToString();
            oBuilder.AppendLine("X: " + textBox1.Text + " Y: " + textBox2.Text);
        }
        StreamWriter oWriter;
        private void Form1_FormClosing(object sender, FormClosingEventArgs e)
        {
            string ContentFile = oBuilder.ToString();
            SaveFileDialog oSDLg = new SaveFileDialog();
            oSDLg.Filter = "(*.txt)|*.txt";
            if (oSDLg.ShowDialog() == DialogResult.OK)
            {
               oWriter = new StreamWriter(oSDLg.FileName);
               oWriter.Write(ContentFile);
               oWriter.Flush();
            }
            oWriter.Close();
        }
