我知道如何使用python通过以下方式在资源管理器中打开文件夹:

subprocess.Popen(r'explorer /select,"C:\path\of\folder"')

但是我不知道如果它已经在资源管理器中“打开”,我怎么防止我的程序打开文件夹。有没有办法在Python中(或通过VBA脚本)?

我认为您的问题主要是由于用户重新打开或使用您的应用重新点击。

部分执行此操作的一种方法可能是:

您可以在变量中存储您打开的资源管理器的pid(进程-id):subprocess.Popen(r'explorer /select,"C:\path\of\folder"')

然后当试图再次打开时,如果设置了pid。检查进程是否仍处于活动状态。如果是的话,那就不要打开它,也许找到一种方法来关注被打开的寡妇。

这是一个有趣的线程,我找到了一个列出打开文件夹的工作解决方案与VBS脚本,但我不知道如何使用VBS,因此我无法解决identifier excepted错误并使其正常工作..

代码本身是:

Imports System.Runtime.InteropServices

导入System.Text

Public Class Form1     Private Const WM_GETTEXT As Integer =& HD     Private Const WM_GETTEXTLENGTH As Integer =& HE

<DllImport("user32.dll", EntryPoint:="FindWindowExW")> _
Private Shared Function FindWindowExW(ByVal hwndParent As System.IntPtr, ByVal hwndChildAfter As System.IntPtr, <InAttribute(), MarshalAs(UnmanagedType.LPTStr)> ByVal lpszClass As String, <InAttribute(), MarshalAs(UnmanagedType.LPTStr)> ByVal lpszWindow As String) As System.IntPtr
End Function

<DllImport("user32.dll", SetLastError:=True, CharSet:=CharSet.Auto)> _
Private Shared Function SendMessage(ByVal hWnd As IntPtr, ByVal Msg As UInteger, ByVal wParam As Integer, ByVal lParam As StringBuilder) As Integer
End Function

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
    ListBox1.Items.Clear()
    Dim hWinList As New List(Of IntPtr)

    'Get Each Explorer Windows Handle
    Dim hWnd As IntPtr = FindWindowExW(IntPtr.Zero, IntPtr.Zero, "CabinetWClass", Nothing)
    While Not hWnd.Equals(IntPtr.Zero)
        hWinList.Add(hWnd)
        hWnd = FindWindowExW(IntPtr.Zero, hWnd, "CabinetWClass", Nothing)
    End While

    'Loop threw each explorer window in the list and get the text from the Address combobox
    If hWinList.Count > 0 Then
        For Each hChld As IntPtr In hWinList
            Dim hChild1 As IntPtr = FindWindowExW(hChld, IntPtr.Zero, "WorkerW", Nothing)
            Dim hChild2 As IntPtr = FindWindowExW(hChild1, IntPtr.Zero, "ReBarWindow32", Nothing)
            Dim hChild3 As IntPtr = FindWindowExW(hChild2, IntPtr.Zero, "ComboBoxEx32", Nothing)
            Dim len As Integer = SendMessage(hChild3, WM_GETTEXTLENGTH, 0, Nothing)
            Dim sb As New StringBuilder(len + 1)
            SendMessage(hChild3, WM_GETTEXT, len + 1, sb)
            ListBox1.Items.Add(sb.ToString)
        Next
    End If

End Sub

我不确定你的目的是什么,但也许这样的事情会有所帮助:

import os
for root, dirs, files in os.walk(Folder_Root, topdown=False):
    for name in dirs:
        full_path = os.path.join(root, name)
        #use Popen to open the folder here

读取Folder_Root下的所有目录,然后用Popen打开每个目录。每个文件夹只打开一次。只需将Folder_Root替换为实际路径即可。
