Copying and Pasting cs Code

In cs, like in almost any computer programming language, reading data from a file can be tricky. You add extra lines of code to tell the computer what to do. Sometimes you can copy and paste these lines from other peoples’ code.

For example, you can follow the pattern in this listing:

         private void btnExit_Click(object sender, EventArgs e)
         {
             this.Hide();
             frmCustomerProfileEntry o1 = new frmCustomerProfileEntry();
             o1.Hide();
             frmCustomerRegistration o2 = new frmCustomerRegistration();
             o2.Hide();
             frmUpdateCustomerDetails o3 = new frmUpdateCustomerDetails();
             o3.Hide();
             frmUpdateProfile o4 = new frmUpdateProfile();
             o4.Hide();
             frmCustomerOrders o5 = new frmCustomerOrders();
             o5.Hide();
             frmLogin frm = new frmLogin();
             frm.txtUserName.Text = "";
             frm.txtPassword.Text = "";
             frm.ProgressBar1.Visible = false;
             frm.txtUserName.Focus();
             frm.Show();
         }
