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.
Turn on Option Strict in your project's properties, so that you have to be exact about your variable data types.
Create a form called frmMoneySpent - this lets someone applying for a datae input their name and the amount they expect to be spent on them:
This person has modest requirements ...
The dating agency sensibly sets a maximum of £100-per-night spend. Attach code to the OK button to validate this, so that the applicant sees an error message if they get too greedy:
Convert the text entered into a number, and check if this is greater than 100
If the user is within budget, on the other hand, display a welcoming message:
Include the applicant's name in your welcome message
Check that your application works, then close the forms down.
