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(); }
