如何从vb宏取消保护我的VB项目? 我发现这个代码:从VB代码取消保护VBProject

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 

但这种方法不提供Excel 2007工作在它我的IDE显示认证的窗口和打印密码。

然后,我的目标是解除我的VBproject而不显示此窗口。

感谢您的任何帮助。

编辑

转换这一个BLOG post对VBA和VB.Net。

我从未赞成Sendkeys。在某些情况下它们是可靠的,但并非总是如此尽管我有一个API的软角落。

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

下面是一个例子

比方说,我们有一个工作簿谁的VBA项目看起来像这样目前。

enter image description here

LOGIC

  1. 使用FindWindow

  2. 找到 “的VBAProject密码” 窗口的句柄一旦被发现,找到编辑框的手柄该窗口使用FindWindowEx

  3. 一旦找到编辑框的句柄,只需使用SendMessage即可写入。

  4. 使用FindWindowEx

  5. 一旦OK按钮的手柄被发现,只需使用SendMessage点击它找到Buttons在该窗口的句柄。

建议

  1. 对于API的THIS是我可以推荐最好的链接。

  2. 如果您想在API的成为好样的FindWindowFindWindowExSendMessage然后得到一个工具,让你的系统进程,线程,窗口和窗口中消息的图形视图。例如:uuSpy或Spy ++。

这里是间谍++会告诉你 “的VBAProject密码” 窗口

我已经把我的文件的路径.xls像这样设置oWb = xlAp.Workbooks.Open(“C:\ my file.xls”)另外VBAProject密码的窗口在MsgBox出现后仍然显示“VBAProject Password Window没有找到“ – 2013-04-24 09:17:53

我知道你已经锁定了这个新的答案,但我有几个问题与上面的代码,主要是我在办公室的64位(VBA7)正在工作。不过,我也是这么做的,所以代码可以在当前的Excel实例中工作,并添加了更多的错误检查,并将其格式化为只用方法UnlockProject公开的方法粘贴到单独的模块中。

为了充分披露,我开始使用this post中的代码,但它是主题上的变体。

该代码还显示条件编译常量,因此它应该同时兼容Excel的32位和64位两种版本。我用this page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:
