Training - List Boxes
Create a screen containing 2 listboxes, 1 button and a textbox. The screen would then look like this, for example.
Fill the listboxes with 10 random numbers. To do this, use the random generator and the listbox.items.add method.
After clicking the button, make sure an event is started that performs the actions below:
- Go through the 1st listbox in a method with a FOR run and add the numbers into a variable. So you need to program this method and call it from the button-click event. Return the value of the variable (return statement in the method).
- Program a 2nd method (also called from the button-click) as follows: in that 2nd method, go through the 2nd listbox with a WHILE loop and sum the numbers into a 2nd variable. The method returns the sum of all the numbers of listbox2.
- Depending on which variable has the highest result show a text in the result textbox (‘Listbox ?? has the highest value namely: ????’). If listbox1 has the highest value you make that listbox green and the other red and vice versa.
