Utilisation d'EditPoint, exemple
Les macros complémentaires Visual Studio sont déconseillées dans Visual Studio 2013. Vous devriez mettre vos macros complémentaires à niveau vers des extensions VSPackage. Pour plus d'informations sur les mises à jour, consultez FAQ : conversion de compléments en extensions VSPackage.
L'exemple suivant crée un objet TextDocument, lui ajoute du texte, puis montre certaines fonctionnalités de l'objet EditPoint.
Exemple
Description
Ce sont des fonctions de base 1 pour les offsets de caractères, tandis que les IVsTextView et les interfaces similaires sont de base zéro. EditPoint est de base 1 car il permet de prendre en charge l'automation VB.
Pour exécuter cet exemple, créez un projet Complément Visual Studio et dans l'Assistant, spécifiez qu'il doit créer un élément de menu Outils. Lorsque vous générez et exécutez le complément, cliquez sur la commande appropriée dans le menu Outils pour exécuter le code.
