En m'inspirant de ce que m'a donné l'enregistreur automatique de macro, j'ai enfin réussi à la faire!

Il était surtout de question de donner un point de départ à mes actions avec des lignes du type:
dim args1(0) as new com.sun.star.beans.PropertyValue
args1(0).Name = "ToPoint"
args1(0).Value = "$D$20"

Là ça marche mais je suis sûr qu'il y a un paquet de lignes inutiles, mais c'est pas grâve! Merci encore Dave!
