Develop a VB program that keeps track of your daily exercise time. The user interface should look similar to the picture below.
1. On Form1, each day's exercise time can be saved into a listbox. Type a number in the textbox, when the "Save" button is clicked, the number should be saved into the listbox. As the Figure shows, 6 numbers have been saved.
2. When the "Draw Chart" button is clicked, Form2 should pop up. A histogram should be shown based on the numbers in the listbox on Form1. When more numbers are saved into the listbox and the "Draw Chart" button is clicked again, the histogram should reflect the new data.
