POThe method is not being called. I think maybe something with a parameter?

    <p><code>WindowsFormsApplication2.Form1.BankAccount</code> does not contain a definition for <code>withBox</code> and no extension method <code>withBox</code> accepting a first argument of type <code>WindowsFormsApplication2.Form1.BankAccount</code> could be found (are you missing a using directive or an assembly reference?)</p> <p>This is one the <code>num1 = Convert.ToDecimal(this.withBox.Text);</code> line of code.</p> <p>Earlier I asked a question about this, and did much more research into my problems. I believed I did everything correct this time. But still getting errors. I am unsure of what I am doing wrong now.</p> <pre><code>using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Linq; using System.Text; using System.Windows.Forms; namespace WindowsFormsApplication2 { public partial class Form1 : Form { BankAccount a = new BankAccount(); public Form1() { InitializeComponent(); decimal iBa = 300.00m; this.aMtBox.Text = iBa.ToString(); } private void dep_Click(object sender, EventArgs e) { try { decimal num1 = 0.00m; decimal iBa = 300.00m; num1 = Convert.ToDecimal(this.depBox.Text); decimal total = num1 + iBa; this.aMtBox.Text = total.ToString(); } catch { MessageBox.Show("ERROR", "Oops, this isn't good!", MessageBoxButtons.OK, MessageBoxIcon.Error); } } public void withdrawl_Click(object sender, EventArgs e) { this.aMtBox.Text = a.Balance.ToString(); } public class BankAccount { decimal balance; decimal iBa; decimal num1; public decimal Balance { get {return balance;} } public decimal IBa { get {return iBa;} } public decimal Num1 { get {return num1;} } public BankAccount() { iBa = 300.00m; num1 = Convert.ToDecimal(this.withBox.Text); balance = iBa - num1; } } } </code></pre> <p>}</p>

    1. COIn the context it's being used, `this` refers to an instance of `BankAccount`. `BankAccount` doesn't have a `withBox`. It's probably in `InitializeComponent`. But all that said, a `BankAccount` instance is not inherently tied to it's "parent" `Form1` just because you instantiate it there. What if you, in `static void Main()`, do `new Form1.BankAccount()` 100 times (note: you won't create 100 forms)? What do you expect `this` to be?

    3. COAt any rate, instantiating `BankAccount` as part of constructing `Form1` is way too early to meaningfully use `withBox.Text`.

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.
