Bonjour ,

mon projet consiste à réaliser une application de scan réseau et de port
mes problèmes :
1/ au niveau de l'interface scan de port le menu est visible au début mais lorsque je démarre le scan , le sous menu devient invisible
2/ comment je fait l'opération d'enregistrer sous des listes des ports retouvés (dans le textarea).
3/ dans le menu édition j'ai les opération couper, copier et coller . est ce que je doit mettre dans chaque évenement
4/au niveau de l'interface scan réseau, j'ai fait l'affichage des adresses ip , hostname et adresse mac. comment je peut afficher directement l'adresse ip de la machine retrouvée dans champ adresse ip de l'interface scan de port.

voici mes codes :
