Answer 1

In the FormClosing event, set e.Cancel to true before returning.

Answer 2

If you have already created the handler for the FormClosing event, just set the FormClosingEventArgs.Cancel property to True to cancel the closure of the form.

private void Form1_FormClosing(object sender, FormClosingEventArgs e)
{
  if(myConditionsAreMet == false)
    e.Cancel = true;
}
