使用shell32.dll解压缩受密码保护的zip文件 [英] decompress password protected zip files using shell32.dll

问题描述

大家好，

我想用shell32.dll解压缩zip文件(我试图不使用第三方组件).

一切都很好.但是我找不到解压缩受密码保护的zip文件的方法！

Hi guys,

I want to decompress zip files with shell32.dll ( I am trying not to use third party components).

Every thing is working fine. But I could not find a way to decompress password protected zip files!!

Shell32.ShellClass sc = new Shell32.ShellClass();
Shell32.Folder SrcFlder = sc.NameSpace("c:\\test1.zip");
Shell32.Folder DestFlder = sc.NameSpace("c:\\test");
Shell32.FolderItems items = SrcFlder.Items();
DestFlder.CopyHere(items,20);

如果test1.zip受密码保护，它将显示一个对话框窗口，用于输入密码！
有什么办法可以通过密码传递密码? (我想在Windows服务中使用此代码！)

谢谢.

If test1.zip is password protected, it will show a dialog window to enter the password!
Is there any way to pass the password through the code? ( I want to use this code in a windows service!)

Thanks.

推荐答案

没有.无法通过任何合法"代码传递此信息.

Nope there is not. There is no way to pass this through any "legal" code.

嗨.

我只是遇到了同样的问题，自己找到了解决方法.
也许知道您或其他任何人仍然可能感兴趣.

所以，我所做的基本上是:

添加具有API函数的模块以将找到的窗口设置在前景中:

Hi.

I just had the same problem and found a workaround bymyself.
Maybe know you or anyone else could be still interested in.

So,what I did was basically:

Add a module with an API function to setthe found window in foreground:

Module mdlWinAPI
    Public Declare Ansi Function SetForegroundWindow Lib "user32.dll" _
     Alias "SetForegroundWindow" (ByVal hwnd As IntPtr) As Boolean
End Module

然后，我在表单中添加了一个计时器，设置为1/4秒-只是看是否有一个窗口具有该特定的标题("Password Richiesta").您必须将该字符串更改为您的语言本地化，即:"Required Password".

计时器内的代码是:

Then, I added a timer to my form, set to 1/4 second - just to look if there''s a Window wich has that specific Caption ("Password Richiesta"). You must change that string to your language localization, i.e.: "Required Password".

The code inside the timer is:

Private Sub tmrCheck_Tick(ByVal sender As Object, ByVal e As EventArgs) _
 Handles tmrCheck.Tick
    ' Specify part of the window title you want.
    ' Get its window handle.
    Dim hwnd As IntPtr = Window_FindPartialTitle("Password Richiesta")
    If hwnd <> IntPtr.Zero Then
        tmrCheck.Stop()
        ' Set it foreground.
        SetForegroundWindow(hwnd)
        ' Insert the password.
        SendKeys.Send(Pwd_VideoPress)
        ' Send ENTER.
        SendKeys.Send("{ENTER}")
    End If
End Sub

使用哪种方法:

Which uses the method:

Private Function Window_FindPartialTitle(ByVal partialTitle As String) _
 As IntPtr
    ' Find handle by partial window title
    For Each p As Process In Process.GetProcesses()
        If p.MainWindowTitle.IndexOf(partialTitle, 0, StringComparison.CurrentCultureIgnoreCase) > -1 Then
            Return p.MainWindowHandle
        End If
    Next
    Return IntPtr.Zero
End Function

我其余的代码没有做很多事情:显示zip文件中的文件，然后将它们解压缩到指定的文件夹中.

希望有人会发现此解决方法有帮助.

The rest of my code doesn''t do much: Shows the files inside the zip and Unzips them to a specified folder.

Hope that someone will find this workaround helpful.
