Remarques

L’indication du contrôle équivaut à définir la propriété Visible sur true.Showing the control is equivalent to setting the Visible property to true. Après l’appel de la méthode Show, la propriété Visible retourne la valeur true jusqu’à ce que la méthode Hide soit appelée.After the Show method is called, the Visible property returns a value of true until the Hide method is called.
