windows forms and oject attributes

[jimache]

Hi everyone,

I am a newbee in C# and I really need help.

have to do a credit card application. I have a abstract class Account which is inherited by
a RegularAccount, SilverAccount... etc, and its methods are overriden by coresponding methods in the child classes, the new objects are created by clicking a AddAccount button.

By clicking a button AddAccount on the mainForm a new form is oppened (which has combo box, and FName and LName text boxes)and then by clicking a button on the opened form an instance of Account is created( can be Regular, Silver...)...I want to be able to click another button on the mainForm(besides AddAccount) which opens a new form which displays account information(balance, payments..etc).

How can I pass the attributes of the newly created object( Account myAccount = new RegularAccount) to this form( the one that displays the account info).

TY , I really apreaciate your help.

As I can see you have a parent form named mainForm with two child forms, let say : NewAccountForm and AccountInfoForm.
It is depending on your requirements to decide where to store the Account objects and how and how many.
I see the following classes:
abstract class Account; and IAccount class where you put the interface that should be implemented in the derived classes such as :

double Balance(){}
void Payments(),
string Status()
class RegularAccount: Account, IAccount
class SilverAccount: Account, IAccount
etc...
//MainForm.cs

public class MainForm : System.Windows.Forms.Form
//
private Account m_Account;
private NewAccountForm m_NewAccountForm;
private AccountInfoForm m_AccountInfoForm;
public MainForm( )
{
this.IsMdiContainer = true;
// initialize mainform

}
private void AddButton_Click(object sender, System.EventArgs e)
{
m_NewAccountForm = new NewAccountForm();
m_NewAccountForm.MdiParent = this;
m_NewAccountForm.Show();
// other code here

}
private void InfoButton_Click(object sender, System.EventArgs e)
{
m_AccountInfoForm = new AccountInfoForm();
m_AccountInfoForm.MdiParent = this;
m_AccountInfoForm.Show();
// other code here to show the account info

}

//
//NewAccountForm.cs
public class NewAccountForm : System.Windows.Forms.Form
// Here you store the created account object like:
ParentForm.m_Account = new RegularAccount();

//AccountInfoForm.cs
public class AccountInfoForm : System.Windows.Forms.Form

// Here you access the Account object stored in the MainForm like:
double d = ParentForm.m_Account.Balance();

There are also other solutions but I think you can get a hint from here.
