Exemples

Cet exemple illustre les CursorLeft CursorTop Propriétés et, ainsi que SetCursorPosition les Clear méthodes et. L’exemple positionne le curseur, qui détermine l’emplacement où l’écriture suivante aura lieu, pour dessiner un caractère de 5 caractères sur 5 rectangle à l’aide d’une combinaison de chaînes « + », « | » et « - ». Notez que le rectangle peut être dessiné avec moins d’étapes à l’aide d’une combinaison d’autres chaînes.
