    <p>I am trying to get my message box to show the invoice subtotals stored in my array...5 of them to show in a message box using the foreach method. I am supposed to input a wage and it then does some calculation and stores the subtotal value into the array. I declared an array and index called decArray and intIndex. Can anyone tell me what I'm missing or doing wrong? Thank you in advance!</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 InvoiceTotal { public partial class frmInvoiceTotal : Form { public frmInvoiceTotal() { InitializeComponent(); } // TODO: declare class variables for array and list here decimal[] decArray = new decimal[5]; int intIndex = 0; private void btnCalculate_Click(object sender, EventArgs e) { try { if (txtSubtotal.Text == "") { MessageBox.Show( "Subtotal is a required field.", "Entry Error"); } else { decimal subtotal = Decimal.Parse(txtSubtotal.Text); if (subtotal &gt; 0 &amp;&amp; subtotal &lt; 10000) { decimal discountPercent = 0m; if (subtotal &gt;= 500) discountPercent = .2m; else if (subtotal &gt;= 250 &amp; subtotal &lt; 500) discountPercent = .15m; else if (subtotal &gt;= 100 &amp; subtotal &lt; 250) discountPercent = .1m; decimal discountAmount = subtotal * discountPercent; decimal invoiceTotal = subtotal - discountAmount; discountAmount = Math.Round(discountAmount, 2); invoiceTotal = Math.Round(invoiceTotal, 2); txtDiscountPercent.Text = discountPercent.ToString("p1"); txtDiscountAmount.Text = discountAmount.ToString(); txtTotal.Text = invoiceTotal.ToString(); for (intIndex = 0; intIndex &lt;= decArray.Length - 1; intIndex++) { DecArray[intIndex] = InvoiceTotal } } else { MessageBox.Show( "Subtotal must be greater than 0 and less than 10,000.", "Entry Error"); } } } catch (FormatException) { MessageBox.Show( "Please enter a valid number for the Subtotal field.", "Entry Error"); } txtSubtotal.Focus(); } private void btnExit_Click(object sender, EventArgs e) { // TODO: add code that displays dialog boxes here string totalstring = ""; foreach (decimal value in decArray) { totalstring += value + "\n"; MessageBox.Show(totalstring + "\n", "Order Totals"); } this.Close(); } } } </code></pre>

    1. COIs this all of the code? You are using `decArray` to generate the total but are otherwise not using it and are not saving anything into it.

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.
