Excel VBA Up-/从多个SharePoint文件夹下载

Question

我在互联网上找到了使用VBA从SharePoint文件夹下载文件的示例代码(在资源管理器中打开，映射到驱动器号等)

因此，我编写了以下代码：

Dim sharepointFolder As String
Dim colDisks As Variant
Dim objWMIService As Object
Dim objDisk As Variant
Dim driveLetter As String

'Create FSO and network object
Set objNet = CreateObject("WScript.Network")
Set fs = CreateObject("Scripting.FileSystemObject")

'Get all used Drive-Letters
Set objWMIService = GetObject("winmgmts:\\" & "." & "\root\cimv2")
Set colDisks = objWMIService.ExecQuery("Select * from Win32_LogicalDisk")

'Loop through used Drive-Letters
For Each objDisk In colDisks
    For i = 65 To 90
        'If letter is in use exit loop and remember letter.
        If i = Asc(objDisk.DeviceID) Then
            j = i
            Exit For
        'letters which are not checked yet are possible only
        ElseIf i > j Then
            driveLetter = Chr(i) & ":"
            Exit For
        End If
    Next i
    'If a Drive-Letter is found exit the loop
    If driveLetter <> "" Then
        Exit For
    End If
Next

'define path to SharePoint
sharepointFolder = "https://spFolder/Sector Reports/"
'Map the sharePoint folder to the free Drive-Letter
objNet.MapNetworkDrive driveLetter, sharepointFolder
'set the folder to the mapped SharePoint-Path
Set folder = fs.GetFolder(driveLetter)

在这个阶段，我可以将文件上传到文件夹：

https://spFolder/Sector Reports/

但是，我也想将文件上传到文件夹中，例如：

https://spFolder/Documents/

我还使用下面的函数删除了前面的驱动器号：

removeDriveLetter "Letter" 

现在我遇到了一个问题，如果我将一个新文件夹映射到一个字母：

mapDriveLetter "A:\", sharepointFolder

并且想要在这封信上保存一些东西，它将始终保存在以前的路径上。例如：

mapDriveLetter "A:\", sharePointFolder1
removeDriveLetter "A:\"
mapDriveLetter "A:\", sharePointFolder2
workbook.saveas "A:\" & workbookName

在这种情况下，工作簿始终保存到"sharePointFolder1“中指定的路径，而不是"sharePointFolder2”中的路径。

我解决这个问题的方法如下：

在将包含所请求文件的每个文件夹连接到网络驱动器号的情况下，我将所有文件夹放入相同的库中，并仅将库的根文件夹连接到网络驱动器号。

在分别使用connection https://spFolder/Sector Reports/和https://spFolder/Documents/的情况下，我将只连接https://spFolder/，并使用文件系统对象浏览子目录。
