PropertySheet() et PSM_CHANGED ...

**dede92** · 05/05/2006, 11h36

Bonjour,
Le bouton "Appliquer", quand je passe sur le dialogue 2 ne s'active pas, alors que dans le dialogue 1, cela fonctionne bien ...
Je ne vois pas pourquoi le fait d'activer "l'onglet 2" fait qu'il ne reconnait plus l'envoi du message "PSM_CHANGED" ....
Quelqu'un aurait il une idée ?
J'ai fait un bout de code ...
Merci d'avance.
