Before you can do this exercise, you'll need to download and unzip this file (if you have any problems doing this, click here for help).

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.

To avoid having to draw the form needed for this exercise, right-click on the name of your project in Solution Explorer then choose Add --> Existing Item... (you can also press SHIFT + ALT + A to do the same thing).

Choose only the file called frmApplication.cs in the above folder to import it into your project (you may need to overwrite existing files as you do this), then edit Program.cs to make this the default form.  When you run your application, you should now see this:

Full application form

This form already includes full validation.

The names of the controls are conveniently shown in the screen shot above!

The Apply button as it stands validates all of the data entered, then currently calls a routine which is commented out:

// if we get here, it's OK to do something with this data - so write out

// values entered to text file

// writeFormData();

Uncomment this procedure call, then write it!  The writeFormData routine should write out to a text file all of an applicant's details.  Here's what this text file might look like after you've written out a few records:

List of applicants

Kermit, gay? Surely not?


When you've got this working, close down your application and any open forms.
