从VB代码解除VBProject的保护

我怎样才能从vbmacros解除我的VB项目？ 我发现这个代码：

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 

但是这个解决scheme不适用于Excel 2007，它在我的IDE中显示了authentication的窗口和打印密码。

然后，我的目标是解除我的VBproject而不显示这个窗口。

感谢您的帮助。

编辑 ：

将其转换为VBA和VB.Net的BLOG文章 。

我从来没有赞成Sendkeys 。 在某些情况下它们是可靠的，但并不总是如此 尽pipe我有一个软的angular落。

您可以实现您想要的function，但是您必须确保您要取消保护VBA的工作簿必须在单独的Excel实例中打开。

这是一个例子

比方说，我们现在有一个VBA项目的工作簿。

逻辑 ：

1. 使用FindWindowfind“VBAProject密码”窗口的句柄

2. 一旦find，使用FindWindowExfind该窗口中编辑框的句柄

3. 一旦find编辑框的句柄，只需使用SendMessage写入即可。

4. 使用FindWindowExfind该窗口中Buttons的句柄

5. 一旦findOKbutton的句柄，只需使用SendMessage来点击它。

build议 ：

1. 对于API 这是我可以推荐的最好的链接。

2. 如果你希望像FindWindow ， FindWindowEx和SendMessage一样擅长使用API​​，那么就可以得到一个工具，让你可以看到系统进程，线程，窗口和窗口消息的graphics化视图。 例如：uuSpy或Spy ++。

Spy ++会显示“VBAProject Password”窗口

testing ：

打开一个新的Excel实例，并将下面的代码粘贴到一个模块中。

代码：（试验和testing）

我已经评论了代码，所以你不应该有任何理解它的问题。

Answer 2

我知道你已经locking了这个新的答案，但我有几个问题与上述代码，主要是我在办公室64位（VBA7）工作。 不过，我也是这样做的，所以代码将在当前的Excel实例中工作，并添加了更多的错误检查，并将其格式化为仅与UnlockProject方法公开的独立模块。

为了充分披露，我真的从这篇文章中的代码开始，尽pipe它是一个主题的变体。

该代码还显示了条件编译常量，因此它应该同时兼容Excel的32位和64位两种版本。 我用这个页面来帮助我解决这个问题。

反正这里的代码。 希望有人认为它有用：
