Write the code for readfile as shown below. For now, you can call this from mnuOpen..
private void readfile() { // Set the filter to show text files or all files. openFileDialog1.Filter = "Text Files|*.txt|All Files|*.*"; openFileDialog1.ShowDialog(); if (openFileDialog1.FileName != "") { currentFileName = openFileDialog1.FileName; this.Text = currentFileName; // Read the entire file into an array. string[] lines = System.IO.File.ReadAllLines(openFileDialog1.FileName); // Add each line to the list box. foreach (string line in lines) { lstData.Items.Add(line); } // The file has just been read, so there are no changes yet. changed = false; } }
To Do: Call readfile from mnuOpen. Make sure this works before proceeding.
