Снять защиту VBProject с кода VB

Как я могу защитить свой проект VB от макроса vb? Я нашел этот код:

Sub UnprotectVBProject(ByRef WB As Workbook, ByVal Password As String) Dim VBProj As Object Set VBProj = WB.VBProject Application.ScreenUpdating = False 'Ne peut procéder si le projet est non-protégé. If VBProj.Protection  1 Then Exit Sub Set Application.VBE.ActiveVBProject = VBProj 'Utilisation de "SendKeys" Pour envoyer le mot de passe. SendKeys Password & "~" SendKeys "~" 'MsgBox "Après Mot de passe" Application.VBE.CommandBars(1).FindControl(ID:=2578, recursive:=True).Execute Application.Wait (Now + TimeValue("0:00:1")) End Sub 

Но это решение не работает для Excel 2007. Он отображает окно аутентификации и печатает пароль в моей среде IDE.

Тогда моя цель – снять защиту с VBproject без отображения этого windows.

Спасибо за любую помощь.

EDIT :

Преобразовал это в сообщение BLOG для VBA и VB.Net.

Я никогда не поддерживал Sendkeys . Они надежны в некоторых случаях, но не всегда. У меня есть мягкий угол для API.

То, что вы хотите, может быть достигнуто, однако вы должны убедиться, что рабочая книга, для которой вы хотите защитить VBA, должна быть открыта в отдельном экземпляре Excel.

Вот пример

Предположим, у нас есть рабочая книга, проект VBA которой сейчас выглядит.

ЛОГИКА :

  1. Найдите ручку windows «VBAProject Password» с помощью FindWindow

  2. Как только это будет найдено, найдите дескриптор windows редактирования в этом окне, используя FindWindowEx

  3. Когда дескриптор windows редактирования найден, просто используйте SendMessage для его записи.

  4. Найти дескриптор Buttons в этом окне с помощью FindWindowEx

  5. Когда дескриптор кнопки OK найден, просто нажмите SendMessage чтобы щелкнуть его.

РЕКОМЕНДАЦИЯ :

  1. Для API – это лучшая ссылка, которую я могу порекомендовать.

  2. Если вы хотите хорошо походить на такие API, как FindWindow , FindWindowEx и SendMessage тогда получите инструмент, который даст вам графическое представление процессов, streamов, окон и оконных сообщений системы. Для Ex: uuSpy или Spy ++.

Вот что Spy ++ покажет вам окно «VBAProject Password»

ТЕСТИРОВАНИЕ :

Откройте новый экземпляр Excel и вставьте приведенный ниже код в модуль.

КОД: (ИСПЫТАНИЕ И ИСПЫТАНИЕ)

Я прокомментировал код, поэтому у вас не должно возникнуть проблем с его пониманием.

Я знаю, что вы заблокировали это для новых ответов, но у меня было несколько проблем с вышеуказанным кодом, главным образом, что я работаю в Office 64-bit (VBA7). Однако я также сделал так, чтобы код работал в текущем экземпляре Excel и добавил немного больше ошибок и отформатировал его, чтобы вставить его в отдельный модуль с UnlockProject только методом UnlockProject .

Для полного раскрытия я действительно начал с кода в этом сообщении, хотя это вариант на тему.

Код также показывает условные константы компиляции, так что он должен быть совместим как с 32-битными, так и с 64-разрядными вариантами Excel одновременно. Я использовал эту страницу, чтобы помочь мне разобраться с этим.

В любом случае вот код. Надеюсь, кто-то сочтет это полезным:
