Pb identification control dans dialogue de classe WindowsForms10.EDIT

**r2d2abc** · 26/02/2016, 10h50

Bonjour je cherche à automatiser le remplissage des items d'une dialogue dont je vous ai fait un extract plus bas en utilisant l'api getdlgctrlid.
Cela marche si l'application est lancée et ne se ferme pas ce qui n'est pas acceptable en mode prod. Le pb provient du fait que l'identifiant de certaines zones change à chaque lancement de l'application donc comment faire pour le localiser d'une manière unique. Les lignes sont identifiées en rouge (id/ctrl en rouge gras)
Merci de votre aide

PS: dev sous codeblocks en c/c++ avec des compilateurs (gcc/cbuilder/ms/..)

Tiens c'est vrai, les Windows Forms n'utilisent pas les Control IDs, liant directement le contrôle à un objet à la place...

Tu peux essayer avec les APIs d'accessibilité, ça a une chance de marcher.

**r2d2abc** · 27/02/2016, 09h34

Je vais essayer / Merci de la réponse / A plus tard

Bonsoir, je vous indique la piste. Il faut trouver de manière classique le processid de l'image exécutée. Enfin allouer de la mémoire dans le process pas sur la stack ou mémoire du process appelant. Envoyer le message, récupérer la valeur par un ReadProcessMemory, enfin le changer de wide en char avant de pouvoir l'utiliser.
Vous pouvez faire un sendmessage plutôt qu'avec un timeout, par contre le wide to byte m' a un peu ennuyé au début.
Merci à Médinoc.
Bien à vous

Intéressant, j'ignorait que les contrôles Windows Forms supportaient un tel message.

Assure-toi de traiter l'échec potentiel de OpenProcess(), par contre, car cela ne marchera que sur les processus t'appartenant.

**r2d2abc** · 01/03/2016, 11h18

C 'est clair. Un code plus sécurisé (petit gestion d'exception) va être mis en place.
