Answer 1

Answer:

Programming Language not stated;

But this application definitely requires a graphical user interface platform (so, I'll use Microsoft Visual C# - Winforms).

Controls to be used are.

1. Form

2. List box

I'll name the Form, Form1 and the list box, listbox1.

Explanation:

The code goes thus;

private void Form1_Load(object sender, System.EventArgs e)

{

//Load country into empty listbox

listbox1.Items.Add("Austria");

listbox1.Items.Add("Canada");

listbox1.Items.Add("England");

listbox1.Items.Add("France");

listbox1.Items.Add("Italy");

listbox1.Items.Add("Mexico");

listbox1.Items.Add("Spain");

}

private void listbox1_SelectedIndexChanged(object sender, System.EventArgs e)

{

//Check if an item is really selected

if(listbox1.SelectedIndex >= 0)

{

//Index 0 represents 1st item that was added to the listbox and that's Austria

if(listbox1.SelectedIndex ==0)

{

MessageBox.Show("Vienna");

}

else if(listbox1.SelectedIndex == 1)

{

MessageBox.Show("Toronto");

}

else if(listbox1.SelectedIndex ==2)

{

MessageBox.Show("London");

}

else if(listbox1.SelectedIndex == 3)

{

MessageBox.Show("Paris");

}

else if(listbox1.SelectedIndex ==4)

{

MessageBox.Show("Rome");

}

else if(listbox1.SelectedIndex == 5)

{

MessageBox.Show("Mexico City");

}

else if(listbox1.SelectedIndex == 6)

{

MessageBox.Show("Madrid");

}

}

else

{

MessageBox.Show("No item selected");

}

}
