使用VBA将多个文件复制到单个文件

Question

我正尝试在窗体应用程序中编写代码，其中我可以选择多个文件并将所有选定文件的数据追加到另一个文件（主文件）中。

下面我写了一个函数，调用单击Userform按钮。

同时运行此代码我收到自动化错误-2147221080（800401a8）

在调试时，我发现它在给错误在下面的代码行

设置rngData = shtData重新分配值。 UsedRange

有人可以帮我解决这个问题，我是新来的VBA，并没有得到错误的原因。

Function copyfiles() 
Dim wbkMaster As Workbook 
Dim shtMaster As Worksheet 
Dim rngMaster As Range 
Dim wbkData As Workbook 
Dim shtData As Worksheet 
Dim rngData As Range 
Dim intChoice As Integer 
Dim strPath As String 
Dim strPath1 As String 
Dim array1() As String 
Dim filepath As String 
Dim count As Integer 
Dim i As Integer 

'to select master file 

Application.FileDialog(msoFileDialogOpen).AllowMultiSelect = False 
intChoice = Application.FileDialog(msoFileDialogOpen).Show 
If intChoice <> 0 Then 
strPath = Application.FileDialog(_ 
msoFileDialogOpen).SelectedItems(1) 
End If 

Set wbkMaster = Workbooks.Open(strPath) 
Set shtMaster = wbkMaster.Worksheets(1) 



'to select source file(s) 
    Application.FileDialog(msoFileDialogOpen).AllowMultiSelect = True 

    intChoice = Application.FileDialog(msoFileDialogOpen).Show 

    If intChoice <> 0 Then 
    For i = 1 To Application.FileDialog(msoFileDialogOpen _ 
).SelectedItems.count 
strPath = Application.FileDialog(msoFileDialogOpen _ 
).SelectedItems(i) 
filepath = filepath & strPath & "," 
Next i 
End If 

array1 = Split(filepath, ",", -1, vbBinaryCompare) 
count = i - 1 
Set rngMaster = shtMaster.Range("A65536").End(xlUp).Offset(1, 0) 
For j = 0 To count - 1 

Set wbkData = Workbooks.Open(array1(j)) 
Set shtData = wbkData.Worksheets(1) 
Set wbkMaster = Workbooks.Open(strPath) 
Set shtMaster = wbkMaster.Worksheets(1) 
Set rngData = shtData.UsedRange 

' copy data across 
rngData.Copy rngMaster 

' simply close data 
wbkData.Close False 

' release objects 
Set rngData = Nothing 
Set shtData = Nothing 
Set wbkData = Nothing 

wbkMaster.Close True 

Set shtMaster = Nothing 

Set wbkMaster = Nothing 

Next 

    Set rngMaster = Nothing 
End Function

我想你应该试试Ron deBruin的代码。
