C#: comctl32.dll version 6 dans le débogueur

Question

J'utilise le WindowsAPICodePack pour TaskDialog. Lorsque j'essaie d'afficher la boîte de dialogue, elle indique qu'elle doit charger la version 6 de comctl32.dll. J'ai donc ajouté la version 6 à app.manifest et j'ai essayé de l'exécuter. Toujours pas de chance. Je suis allé au dossier Déboguer et ai couru le programme sans Visual Studio et cela fonctionne très bien. Je devine que Visual Studio n'utilise pas le fichier manifeste ... Je me demandais s'il y avait un moyen de le faire faire.

Answer 1

Rob pol86, votre code lance SEHExceptions, car les signatures pour ActivateActCtx et DeactivateActCtx ne sont pas correctes. Vous devez utiliser UIntPtr au lieu de uint pour le lpCookie.

Par conséquent, le bon code pour EnableThemingInScope.cs serait:

using System; 
using System.IO; 
using System.Runtime.InteropServices; 
using System.Security; 
using System.Security.Permissions; 
using System.Windows.Forms; 

namespace Microsoft.WindowsAPICodePack.Dialogs 
{ 
    /// http://support.microsoft.com/kb/830033 
    /// <devdoc> 
    ///  This class is intended to use with the C# 'using' statement in 
    ///  to activate an activation context for turning on visual theming at 
    ///  the beginning of a scope, and have it automatically deactivated 
    ///  when the scope is exited. 
    /// </devdoc>

     private static IntPtr hActCtx; 
     private static bool contextCreationSucceeded = false; 

     public EnableThemingInScope(bool enable) 
     { 
      cookie = UIntPtr.Zero; 
      if (enable && OSFeature.Feature.IsPresent(OSFeature.Themes)) 
      {

       { 
        if (!ActivateActCtx(hActCtx, out cookie)) 
        {

Answer 2

Cette page décrit comment ajouter un manifeste personnalisé à votre projet afin de dire Windows pour charger la nouvelle comctl32.dll (version 6.0):

• Setting the correct manifest version

Votre manifeste ont la bonne dépendance sur comctl32.dll? Avez-vous intégré le manifeste créé?

Answer 3

J'ai le même problème avec Visual Studio en mode débogage. Jusqu'à présent, je n'ai pas trouvé de solution de contournement, cela fonctionne très bien en mode Release.

Answer 4

J'ai récemment rencontré ce problème lors du débogage du code avec TaskDialogDemo dans le CodePack. C'est comme ça que je l'ai réparé. Le problème avec l'utilisation de ceci est que si j'ouvre deux ou trois boîtes de dialogue il lance une SEHException, que je n'ai pas trouvée comment réparer. Alors acheteur méfiez-vous.
