    <p>I'm just getting started with C# and I've been stuck on this problem for two weeks. I have a main form that gets values from a class and a subclass. My problem is that when I try to create an object of the CorporateClass VB tells me that two of my variables (CarSizeInteger and DiscountInteger) are unassigned. My question is why. I implemented them earlier in the program. Help! I'm hopelessly stuck!</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 EX02_CarRentals { public partial class RentalForm : Form { public RentalForm() { InitializeComponent(); } private void CloseButton_Click(object sender, EventArgs e) { Close(); } private void CalculateButton_Click(object sender, EventArgs e) { int DaysInteger, BeginningOdometerInteger, EndingOdometerInteger, CarSizeInteger, DiscountInteger; if (LicenseTextBox.Text != "") if (CompactRadioButton.Checked || MidSizeRadioButton.Checked || LuxuryRadioButton.Checked) { int.TryParse(DaysRentedTextBox.Text, out DaysInteger); int.TryParse(BeginningOdometerTextBox.Text, out BeginningOdometerInteger); if (BeginningOdometerInteger &gt; 0) { int.TryParse(EndingOdometerTextBox.Text, out EndingOdometerInteger); if (EndingOdometerInteger &gt; 0) { if (CompactRadioButton.Checked) CarSizeInteger = (int)CarSize.Compact; else if (MidSizeRadioButton.Checked) CarSizeInteger = (int)CarSize.MidSize; else CarSizeInteger = (int)CarSize.Luxury; } { if (CorporateRadioButton.Checked || InsuranceRadioButton.Checked) { if (CorporateRadioButton.Checked) DiscountInteger = (int)Discount.Corporate; else if (InsuranceRadioButton.Checked) DiscountInteger = (int)Discount.Insurance; //create an instance of the Corporate Class CorporateClass aCorpRental = new CorporateClass(BeginningOdometerInteger, EndingOdometerInteger, CarSizeInteger, DaysInteger, DiscountInteger); AmountDueTextBox.Text = (aCorpRental.getAmountDue()).ToString("C"); } else { //create an instance of the Rental Class RentalRate ARental = new RentalRate(BeginningOdometerInteger, EndingOdometerInteger, CarSizeInteger, DaysInteger); AmountDueTextBox.Text = (ARental.getAmountDue()).ToString("C"); } } } } } } private void DaysRentedTextBox_TextChanged(object sender, EventArgs e) { } } } </code></pre>

    1. COI'm dying to know why you thought leaving your code all messed up like that was acceptable?

    3. COFYI, in C# it is idiomatic to name local variables starting with lowercase. In neither C# nor VB is it a good idea to name variables with their type; the name of the variable should describe its *purpose*, not its storage.

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.
