Visual C# | Validating forms exercise | Incorporate a NumericUpDown in a form
This exercise is provided to allow potential course delegates to choose the correct Wise Owl Microsoft training course, and may not be reproduced in whole or in part in any format without the prior written consent of Wise Owl.
The answer to the exercise will be included and explained if you attend the relevant Wise Owl course (sadly, only in the UK for now).

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.
This exercise asks you to create a NumericUpDown control to ensure someone's age is filled in as an integer. First add the form called frmNewHeart from the folder above into your project (or use a version you already have).
Delete the textbox for entering this person's age, and replace it with a NumericUpDown control:
Give your control appropriate minimum, maximum and increment values
When a user clicks on the Apply button, they should see their name and age:
Your confirmation message should look something like this
When everything's working OK, close down this form.
