You need a minimum screen resolution of about 700 pixels width to see our exercises. This is because they contain diagrams and tables which would not be viewable easily on a mobile phone or small laptop. Please use a larger tablet, notebook or desktop computer, or change your screen resolution settings.
Add the form called frmNewHeart in the folder above into your project (or use one you already have).
Delete the textbox for entering this person's age, and replace it with a NumericUpDown with appropriate minimum, maximum and increment values:
Clicking on the arrow shown should subtract 1 from the age, until a minimum of 18 is reached
Your Apply button should display the person's age, when clicked:
Far too young to enter the Matrix ...
Check your application works, then close down your form.
