A lot of books deal with the console side of c# more than the form side.

MessageBox.Show("The Yes button was clicked", "My form event handler", MessageBoxButtons.OK, MessageBoxIcon.Information);

    {
    MessageBox.Show("The Yes button was clicked", "My form event handler", MessageBoxButtons.OK, MessageBoxIcon.Information);

private           So that it is only usable inside the form.
void              Because it doesn't return a value
YesButton_Click   Name of the handler method: YesButton Click event
object sender     "sender" is object that raised the event (useful if several buttons share the same handler)
EventArgs e       Provides extra information on the event if you need it.

a TextBox 'tbxQuizQuestion

I don't need that sound.
