Restaurant Cash Register

[marie]

I have a code and a dll that i made.

It's a windows application of a Restaurant Cash Register

The selected items from each category (listBox1 and listBox3) are copied on listBox2. How can i sum the items on listBox2 and make it display it on the textBox1 below?

Thanks,

This is my DLL:

using System;

namespace ClassLibrary1
{
/// <summary>
/// Food class that holds the name and the price of a single food item.
/// Regular Menu class and Kid Menu Class that inherits from the Food class.
/// Choices class which contain an array of Regular Menu and/or Kid Menu objects.
/// </summary>

// parent class
public class Food
{ // starts class food

public string name;
public double price;

public Food() // default constructor - initializes name and price to its lowest values.
{
name = " ";
price = 0.00;
}

public Food( string iName, double iPrice) // constructor takes two arguments of type string & double
{
name = iName;
price = iPrice;
}

public string iName // functions set and get for iName
{
get
{
return name;
}
set
{
name = value;
}
}

public double iPrice // functions set and get for iPrice
{
get
{
return price;
}
set
{
price = value;
}
}

} //ends class Food

public class RegularMenu : Food // starts class RegularMenu which inherits from class Food
{

public RegularMenu(string iName, double iPrice) // constructor takes two arguments of type string & double
{
name = iName;
price = iPrice;
}

} // ends class RegularMenu


public class KidMenu : Food // starts class KidMeni which inherits from class Food
{
public KidMenu(string iName, double iPrice) // constructor takes two arguments of type string & double
{
name= iName;
price = iPrice;

}

} // ends class KidMenu


public class Selection // starts class Selection
{
// arrays of objects of RegularMenu and KidMenu
private RegularMenu[] rmenu = new RegularMenu[50];
private KidMenu[] kmenu = new KidMenu[50];

private int sizeRegmenu =0;
private int sizeKidmenu =0;

public int sizereg // get/set functions
{
get
{
return sizeRegmenu;
}
}

public int sizekid
{
get
{
return sizeKidmenu;
}
}


public Selection()
{
rmenu[0]= new RegularMenu("pizza slice", 2.50);
rmenu[1]= new RegularMenu("hamburguer", 1.75);
rmenu[2]= new RegularMenu("salad", 1.90);
rmenu[3]= new RegularMenu("large soda", 1.20);
rmenu[4]= new RegularMenu("medium soda", 0.90);

sizeRegmenu = 5;

kmenu[0]=new KidMenu("hot dog", 1.50);
kmenu[1]= new KidMenu("small soda", 0.60);
kmenu[2]= new KidMenu("cookie", 0.86);

sizeKidmenu =3;

}

public void add_rmenu( RegularMenu m)
{
rmenu[++ sizeRegmenu] = m;
}

public void add_kid(KidMenu m)
{
kid[++sizeKidmenu] = m;
}


}

}

------------------------

This is the code right now but it gives me some errors. I think i should put the class Selections (That's on the DLL) on the code, but im not sure and i did it and it still gave me some errors.. Can someone help me?:

create a new class for the item so you can have it as an object, then override the to string to display the text as you want it... but to sum it go through each object in the one you want to sum call its price and add that up

this is VB.NET code

Public Class FoodItem

private name as string = string.empty

private price as decimal = 0d

public sub new(byval ItemName as string, byval Price as decimal)

price = Price

name = ItemName

end sub

Public Function Overrides ToString() as string

' this will be displayed when added to items collection of list box

return ItemName & " " & price

end function

public property Price as decimal

get

return price

end get

end property

end class

then make a new object for each item of that class type

me.listbox1.add(new FoodItem("Hamburger","1.99")

me.listbox1.add(new FoodItem("Cheeseburger","2.30")

to sum it

dim totalPrice as decimal = 0d

for each FoodItem in me.listbox1.items

totalPrice += FoodItem.price

next

that is VB.NET code, but C# is the same way just change the syntax

Ok, so i put this new class in the code or in the DLL?

put it with your other code where you will be using it
