bonjour,
voilà j'ai créer une form permettant d'afficher des identifiants et mot de passes, celle-ci est composer de :
1 label et 1 textbox "recherche"
1 boutton "valide"
1 label "id" et 10 textbox "Id"
1 label "mdp" et 10 textbox "mdp"

le principe est :
si texbox "recherche" = vide
alors label "id & "mdp" visible = false
et
boutton "valide" enabled = false

voilà pourquoi dans le code vous pourrez voir que j'utilise plusieurs fois :

1 / y'aurait-il un moyen plus simple et plus court surtout pour raccourcir le code ?
2 / sachant que tout les "id " et "mdp" sont écris dans le code si je désire ne pas les entrées dans le code (éventuellement pour que l''application puisse être utiliser pour plusieurs personne) quel solution y'aurai t-il ?

Encore une fois merci de l'aide et du temps apporté
