Answer 1

To insert the file path on click of button named "Browse_Button" with file name in text box named "ARfilePath" the above code will be modified as:

    private void Browse_Button_Click(object sender, EventArgs e)
    {
        Stream myStream = null;
        OpenFileDialog openFileDialog1 = new OpenFileDialog();

        openFileDialog1.InitialDirectory = "c:\\";
        openFileDialog1.Filter = "txt files (*.txt)|*.txt|All files (*.*)|*.*";
        openFileDialog1.FilterIndex = 2;
        //openFileDialog1.RestoreDirectory = true;
        Boolean FileExist=openFileDialog1.CheckFileExists;
        Boolean PathExist=openFileDialog1.CheckPathExists;
        openFileDialog1.FileName = null;
        if (openFileDialog1.ShowDialog() == DialogResult.OK)
        {
            try
            {
                if ((myStream = openFileDialog1.OpenFile()) != null)
                {
                    using (myStream)
                    {
                        if (FileExist == true && PathExist == true)
                        {
                            // Insert code to read the stream here.
                            string Pathname = openFileDialog1.FileName;
                            ARfilePath.Text = Pathname;
                            ARfilePath.Enabled = false;
                            /*DISABLED SO THAT THE USER CANNOT MAKE UNNECESSARY CHANGES IN THE FIELD*/
                        }
                    }
                }
            }
            catch (Exception ex)
            {

                /*SHOW ERRORS TO USER*/ error_label.Text = "Error: Could not read file from disk. Original error: " + ex.Message;

                //MessageBox.Show("Error: Could not read file from disk. Original error: " + ex.Message);
            }
        }
    }
