Question valeur fonction dans plusieurs fonctions

Bonjour,

J'ai actuellement un soucis de scope concernant une variable qui m'embête car elle ne veut pas se mettre en global...

Voici le script qui est assez long, la partie qui m'intéresse est celle de la fonction TreeView, qui a dedans, une fonction Get-CheckedNode, et j'aimerai retourner la valeur de ce Get-CheckedNode Lorsque je clique sur un bouton (Export-GPO) par exemple.

J'ai trouvé, il s'agissait en fait de mettre en fin de function TreeView $global:ResultatNode = GetCheckedNode($TV)

Et d'appeler $global:ResultatNode lorsque je clique sur le bouton Exporter-GPO par exemple.

Ca a l'air de fonctionner.

Si ça peut en aider certains.
