This exercise is provided to allow potential course delegates to choose the correct Wise Owl Microsoft training course, and may not be reproduced in whole or in part in any format without the prior written consent of Wise Owl.
If you haven't already got one, create a Windows Forms project (using Visual C#, obviously) called wiseowl. Right-click on your project in Solution Explorer to add an existing item, and choose the file frmShopping.cs in the above folder.
Make this the default form in Program.cs. When you run your application, you should be able to add an item to your shopping list:
The idea is that when you click on the Add item button, the item you've typed in should appear in the text box on the right.
Read on to find how to do this!
Create a class called ShoppingItem to hold each item, with the following properties:
Property | Notes |
---|---|
ItemName | The name of each item |
UnitName | The units for each item |
Amount | The amount to buy |
Description | The description of the item to be added to the text box on the right |
If all goes well you should be able to attach the following code to the Add item button (or something similar to it) to get your system working:
// create a new item for your shopping list
var thing = new ShoppingListItem();
thing.ItemName = txtItem.Text;
thing.UnitName = txtUnit.Text;
thing.Amount = Amount;
// add the item to your list
// (adding carriage return first, if not first item)
if (txtList.Text.Length > 0) {
txtList.Text += Environment.NewLine;
}
txtList.Text += thing.Description;
Add a few items to your list, and check that they appear in the text box!
