Excel VBA - 将多个工作簿合并到单个工作表中

我正在尝试将多个excel工作簿合并到单个工作表中 . 我找到了其他网站的代码，它设法选择文件夹并将文件夹中的所有excel文件合并到当前活动的工作簿中 . 目标工作簿包括2张PID和服务 . 以下是代码：

Option Explicit
Public strPath As String
Public Type SELECTINFO
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

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 SELECTINFO) As Long
Function SelectFolder(Optional Msg) As String
Dim sInfo As SELECTINFO
Dim path As String
Dim r As Long, x As Long, pos As Integer
sInfo.pidlRoot = 0&

If IsMissing(Msg) Then
    sInfo.lpszTitle = "Select your folder."
Else
    sInfo.lpszTitle = Msg
End If

sInfo.ulFlags = &H1

x = SHBrowseForFolder(sInfo)

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

"Merging Part"
Sub MergeExcels()
Dim path As String, ThisWB As String, lngFilecounter As Long
Dim wbDest As Workbook, shtDest As Worksheet, ws As Worksheet
Dim Filename As String, Wkb As Workbook
Dim CopyRng As Range, Dest As Range
Dim RowofCopySheet As Integer

RowofCopySheet = 1 

ThisWB = ActiveWorkbook.Name

path = SelectFolder("Select a folder containing Excel files you want to merge")

Application.EnableEvents = False
Application.ScreenUpdating = False

Set shtDest = ActiveWorkbook.Sheets(1)
Filename = Dir(path & "\*.xls", vbNormal)
If Len(Filename) = 0 Then Exit Sub
Do Until Filename = vbNullString
    If Not Filename = ThisWB Then
        Set Wkb = Workbooks.Open(Filename:=path & "\" & Filename)
        Set CopyRng = Wkb.Sheets(1).Range(Cells(RowofCopySheet, 1), Cells(ActiveSheet.UsedRange.Rows.Count, ActiveSheet.UsedRange.Columns.Count))
        Set Dest = shtDest.Range("A" & shtDest.UsedRange.SpecialCells(xlCellTypeLastCell).Row + 1)
        CopyRng.Copy Dest
        Wkb.Close False
    End If

    Filename = Dir()
Loop

Range("A1").Select

Application.EnableEvents = True
Application.ScreenUpdating = True

MsgBox "Files Merged!"
End Sub

我的工作簿需要先复制Sheet1（PID），第二个动作需要复制Sheet2（服务） . 但是我发现的代码只能合并sheet1（PID） . 我试着调整代码，但没有运气 . 以下是我试图调整的部分：

Set shtDest = ActiveWorkbook.Sheets(1)
Filename = Dir(path & "\*.xls", vbNormal)
If Len(Filename) = 0 Then Exit Sub
Do Until Filename = vbNullString
    If Not Filename = ThisWB Then
        Set Wkb = Workbooks.Open(Filename:=path & "\" & Filename)
        Set CopyRng = Wkb.Sheets(1).Range(Cells(RowofCopySheet, 1), Cells(ActiveSheet.UsedRange.Rows.Count, ActiveSheet.UsedRange.Columns.Count))
        Set Dest = shtDest.Range("A" & shtDest.UsedRange.SpecialCells(xlCellTypeLastCell).Row + 1)
        CopyRng.Copy Dest
        Wkb.Close False
End If

我试图将ActiveWorkbook.Sheets（1）更改为ActiveWorkbook.Sheets（2）并将Copy CopyRng = Wkb.Sheets（1）更改为Set CopyRng = Wkb.Sheets（2），但没有运气 . 希望你们能帮助我 . 谢谢
