Est-il possible de capturer des événements lorsque vous appuyez sur une touche pour effectuer une modification dans une cellule spécifique d'une feuille de calcul?
La personne la plus proche connue est l'événement Change
, mais il ne peut être activé que lorsque la cellule modifiée est désélectionnée. Je veux capturer l'événement while Je modifie la cellule.
Voici la réponse, j'ai testé le même et cela fonctionne correctement pour moi.
Suivre le pavé numérique dans Excel
Question intéressante: L'événement Worksheet_Change
de MS Excel est toujours déclenché lorsque vous avez terminé vos modifications et que vous sortez de la cellule. Pour intercepter l'événement Key Press
. Le suivi de l'événement Keypress n'est pas possible avec les fonctions standard ou intégrées d'Excel.
Ceci peut être réalisé en utilisant API
.

Je sais que c’est une vieille question, mais j’avais récemment besoin de fonctionnalités similaires et la réponse fournie comportait certaines limitations que je devais aborder en ce qui concerne la manière dont elle traitait (ou ne gérait pas) les touches Suppr, Retour arrière, Touches de fonction, etc.
La solution consiste à renvoyer le message d'origine à la place du message traduit.
J'ai également changé pour utiliser un module de classe avec des événements, car cela fonctionne correctement dans Excel 2010 et je ne voulais pas copier le même code sur plusieurs feuilles:

J'ai eu le même problème, et résolu en plaçant une zone de texte sur la cellule. J'ai défini les propriétés de sorte que la zone de texte ressemble à une cellule Excel, puis j'ai utilisé les propriétés Top et Left pour la positionner sur la cellule à l'aide des mêmes propriétés de la cellule et définir la largeur et la hauteur sur une valeur supérieure à celle de cellule. Puis je l'ai rendu visible. J'ai utilisé l'événement KeyDown pour traiter les frappes au clavier. Dans mon code, j'ai placé une zone de liste sous la cellule pour afficher les éléments correspondants d'une liste sur une autre feuille. Remarque: Ce code était dans la feuille, la variable Cell a été déclarée dans un module: Global Cell as Range. Cela fonctionne beaucoup mieux qu'une boîte à options. tb1 est une zone de texte et lb1 est une zone de liste. Vous aurez besoin d'une feuille nommée Fruit avec des données dans la première colonne. La feuille dans laquelle ce code est exécuté ne sera exécutée que si la cellule sélectionnée est dans la colonne = 2 et est vide. N'oubliez pas de déclarer Cell comme mentionné ci-dessus.
