Question

当我通过Excel运行此代码时，它表示Left（，）函数需要一个数组。我传递的是String，函数需要String，变量声明为String。我把$运算符放在那里它仍然给我废话。知道可能会发生什么吗？

当我通过SolidWorks运行时，FWIW执行得很好。

此外，它是从用户表单调用的，它将String传递给它。

请尝试以下代码，它可以正常工作

Option Explicit

 '32-bit API declarations
Declare Function SHGetPathFromIDList Lib "shell32.dll" _
Alias "SHGetPathFromIDListA" (ByVal pidl As Long, ByVal _
pszpath As String) As Long

Declare Function SHBrowseForFolder Lib "shell32.dll" _
Alias "SHBrowseForFolderA" (lpBrowseInfo As BrowseInfo) _
As Long

Public Type BrowseInfo
    hOwner As Long
    pIDLRoot As Long
    pszDisplayName As String
    lpszTitle As String
    ulFlags As Long
    lpfn As Long
    lParam As Long
    iImage As Long
End Type

Function GetDirectory(Optional msg) As String
    On Error Resume Next
    Dim bInfo As BrowseInfo
    Dim path As String
    Dim r As Long, x As Long, pos As Integer

     'Root folder = Desktop
    bInfo.pIDLRoot = 0&

     'Title in the dialog
    If IsMissing(msg) Then
        bInfo.lpszTitle = "Please select the folder of the excel files to copy."
    Else
        bInfo.lpszTitle = msg
    End If

     'Type of directory to return
    bInfo.ulFlags = &H1

     'Display the dialog
    x = SHBrowseForFolder(bInfo)

     'Parse the result
    path = Space$(512)
    r = SHGetPathFromIDList(ByVal x, ByVal path)
    If r Then
        pos = InStr(path, Chr$(0))
        GetDirectory = Left(path, pos - 1)
    Else
        GetDirectory = ""
    End If
End Function

Sub CombineFiles()
    Dim path            As String
    Dim FileName        As String
    Dim LastCell        As Range
    Dim Wkb             As Workbook
    Dim WS              As Worksheet
    Dim ThisWB          As String

    ThisWB = ThisWorkbook.Name
    Application.EnableEvents = False
    Application.ScreenUpdating = False
    path = GetDirectory
    FileName = Dir(path & "\*.xls", vbNormal)
    Do Until FileName = ""
        If FileName <> ThisWB Then
            Set Wkb = Workbooks.Open(FileName:=path & "\" & FileName)
            For Each WS In Wkb.Worksheets
                Set LastCell = WS.Cells.SpecialCells(xlCellTypeLastCell)
                If LastCell.Value = "" And LastCell.Address = Range("$A$1").Address Then
                Else
                    WS.Copy After:=ThisWorkbook.Sheets(ThisWorkbook.Sheets.Count)
                End If
            Next WS
            Wkb.Close False
        End If
        FileName = Dir()
    Loop
    Application.EnableEvents = True
    Application.ScreenUpdating = True

    Set Wkb = Nothing
    Set LastCell = Nothing
End Sub

左右功能在我的VBA代码中不起作用，期待阵列？
