    <p>I'm having a small problem with this program. This program is designed to use polymorphism. I have written one base class and two derived classes.</p> <p>We are supposed to make a base class(bank Account) array and fill that with three bank account objects. We then assign each bank account object a new object using it's overloaded constructor.</p> <pre><code> public partial class Form1 : Form { //Base class array BankAcct[] b = new BankAcct[3]; public Form1() { InitializeComponent(); //This is not getting current values from form! int accountNum; int atmNum; int pinNum; an = Convert.ToInt32(accountNumber.Text); p = Convert.ToInt32(pin.Text); atm = an - p; //base class b[0] = new BankAcct(name.Text, 500.00M, accountNum); //this derived class inherits from bankAcct name, account number, and //the decimal which is the balance assigned to the Account //private variables are atm and pin in this class b[1]= new SilverBankAcct(name.Text, an, 1500.00M, atmNumber, pinNum); //this derived class inherits from SilverBankAcct atm, pin, //has one private variable the decimal at the end which is the interest b[2] = new GoldBankAcct(name.Text, accountNum, 25000.00M, atm, pinNum, 0.05M); } </code></pre> <p>My problem is that when I instantiate my objects in the Form1 Constructor The fields do not update from the form and the current values in those fields are being ignored. I tried assigning the information by accessing properties in my base class and assigning the values from the form there, but the problem comes when I try to update my atm number and pin number which are private variables that go into my SilverBankAcct class, and GoldBankAcct class.</p> <pre><code>private void button1_Click(object sender, EventArgs e) { b[0].fName = name.Text; b[1].fName = name.Text; b[2].fName = name.Text; //do the same for account number which works, but how am I supposed to update atm and pin from the form when I have no access to these variables I only have access to the base class? } </code></pre> <p>What would be a better way to ensure that the values being passed along are being updated to the current values from the form when the button is clicked?</p>

    1. CODebug your code ans see what happens... Also please make your life easier and don't shorten any words in the code - i.e. `an` is not very nice name for variable as it is very hard to guess meaning of it. Or `Acct` - saving 3 characters and making non-readable identifiers will not make your code better.

    3. COIt looks like you have a design problem, you have to make all member that you want to access from out side of the class available, only then you will be able to do what are want to achieve. If you don;t expose the members via public properties, its not possible to access them right?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
