Displaying the Exercise History

At the moment your app only displays the total minutes exercised, but since you’ve got the list of all the individual sessions, why not show that as well?

• Go to the Designer view, and add a ListView from User Interface.

• If you want, you can also add a label above the list that says something like Exercise history:.

As you might have guessed, a ListView displays a list of things. Similar to how you set the Text property of a Label to some text, you set the Elements property of a ListView to a list. You will do this in two places in your code.

First, you need to update the ListView whenever the user enters a new exercise time.

• In the Button.Click for the Enter button, add a set ListView.Elements to block and a get global minutesList block below AppendToFile.

Secondly, you need to update the ListView whenever you load the list file.

• Find your File1.GotFile code, and add set ListView.Elements to and get global minutesList (the same code as above) right below the set global minutesList to block.

And your app is complete!

Challenge: track the type of exercise

• How about adding another TextBox that lets the user also record what kind of exercise they did? You’ll have to think about what extra code you’ll need, such as lists and loops, and how to store the new information in a file.

• You can either use the same file (with some extra join and split code), or a separate one.
