Bonsoir a toutes et tous, forum bonsoir

Je souhaiterai svp juste savoir jusqu'a combien de controls (tout confondu, labels, textboxs etc etc) on peut mettre dans un userform aussi grand soit-il et si ils faut les répartir dans des Frames, sans que cela pose de problème avec la mémoire ou la gestion d'un grand nombre de controls.

En fait quel est le mieux svp a faire en cas de nombreux controls.

Merci pour les infos a ce sujet et pour vos conseils.

Bonne soirée a tous

Bonjour,

A partir d'une centaine de contrôles lourds, il peut y avoir des problèmes de ralentissements ou même d'erreurs. Le mieux est de splitter ton USF en plusieurs userforms plus légers et répartir le traitement..

Par exemple si tu as besoin de 100 textbox avec 100 labels et 5 boutons, ceci dans 3 frames. Tu ferais mieux de faire deux voir trois USF.

Salut a tous,

Salut EngueEngue

Merci pour ta réponse, c'est sympa, j'ai pu lire 2 /3 articles sur le nombres de controls par USF et visiblement pas tous d'accord.

Bon de toutes facons, je suis d'accord avec toi, diviser pour mieux règner, ca me va bien.

Si j'ai bien compris Ex: les controls qui sont dans l'userform(1) le code a mettre
pour les pilotés doit aller dans

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

Private Sub UserForm_Initialize()

de l'Usf (1)

Idem pour les controls se trouvant dans l'userform(2) etc etc

Merci pour tes infos et conseils

Vu l'heure bon app et a plus tard

Ton Private Sub UserForm_Initialize() va se lancer à l'initialisation de ton USF

Si tu veux faire qqchose en cliquant sur un label, un bouton ou autre il faudra le mettre dans leur propre Sub

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

Private Sub CommandButton1_Click()

Tu peux toujours essayer de blinder ton USF, quand tu commenceras à avoir des erreurs tu sauras que tu es à la limite..

Salut

Merci pour la réponse

je vois maintenant comment faire et utiliser plusieurs userforms en mème temps

je sais les affichées par 2 ou 3
je sais enlever la barre de titre
je sais cacher ou inbiber la croix de l'usf
je sais les déplacer mème lorsque la barre de titre n'ai plus

j'ai lu pleins de tutos pour bidouiller les Usf mais pas trouver
pour cacher, supprimer où changer la couleur du cadre de l'usf

ou écrire differement dans la barre de titre et changement de couleur du fond

pas encore trouver de code pour ce faire, une idée un lien peux etre ???

En tout cas merci pour ton aide, je progresse sur les usfs

Bonne après midi a toi

Sinon une autre technique de bidouillage assez salace: tu hides ta barre de titre du USF et à la place tu mets un label que tu pourras bidouiller...


Je n'ai jamais rendu hipster mes USF, d'une part parce que c'est inutile, et d'une autre parce que le contenu est plus important que le contenant, préoccupe toi de rendre ton usf opérationnel avant de le rendre funky
