Create a form with a button in it. When you click on the button, it should become a bit pinker:
Every time you click on the button, it should become a little bit pinker.
To save looking it up, here's how you could change the background colour of a button referred to as button, where redness is an integer variable which could hold values from 255 (white) to 0 (red):
// create and apply a new colour
Color colour = Color.FromArgb(255, redness, redness);
button.BackColor = colour;
When you load the form, it should create a new object of type PinkButton (you'll need to create this class):
private PinkButton pb;
private void frmColouredButton_Load(
object sender, EventArgs e)
// create a new pink button object
pb = new PinkButton(btnPink);
Subscribe the SayTooPink method of the class (which you need to create) to the GettingTooPink event (which you also need to create!):
// add an event-handler to it
pb.GettingTooPink += pb.SayTooPink;
When you run your program, clicking on the Make pinker button should make it pinker - up to a point:
What you should see if your button is already red and you click on it. The class raises an event to display the message shown.
If you've finished, you could ponder how you could incorporate this application into your organisation's corporate IT platform!
