Exemples
L’exemple suivant illustre l’utilisation de la HelpProvider classe pour afficher l’aide contextuelle sur un formulaire contenant quatre champs d’adresse. L’exemple utilise pour SetHelpString définir le texte de l’info-bulle d’aide. Lorsque vous utilisez le bouton Aide qui respecte le contexte et que vous cliquez sur le curseur Aide dans un champ d’adresse, l’info-bulle d’aide s’affiche avec le texte spécifié. Lorsque vous appuyez sur la touche F1 avec le focus dans un champ d’adresse, le mspaint.chm fichier d’aide s’affiche, car la HelpNamespace propriété a été définie sur mspaint.chm. La SetShowHelp méthode est appelée pour chaque contrôle d’adresse afin d’identifier qu’il dispose d’un contenu d’aide disponible.
