是给朋友整理实验数据用的，两个小需求：
一、要第一列是数据序号，且多个文件数据拷到目的文件的时候数据序号要按顺序排列；
二、每个文件可能有多个worksheet，都要拷贝到目标文件里面。
对于office2003以前的excel，是支持Application.FileSearch的，实现代码如下：
Sub test()
Dim i As Integer,iRow As Integer
Dim strPath As String
Dim TheSheet As Worksheet
iRow = 1
Set TheSheet = ActiveWorkbook.Worksheets("sheet1")
strPath = "D:/Macro/testtest"
With Application.FileSearch
.LookIn = strPath
.SearchSubFolders = True
.Filename = "*.*"
If .Execute > 0 Then
For i = 1 To .FoundFiles.Count
'Range("A" & i) = .FoundFiles(i)
Workbooks.Open (.FoundFiles(i))
For j = 1 To ActiveWorkbook.Worksheets.Count
'ActiveWorkbook.Worksheets(i).Cells(1,1).Value = "a"
ActiveWorkbook.Worksheets(j).UsedRange.copy
TheSheet.Activate
While TheSheet.Range("a" & iRow).Value <> ""
TheSheet.Cells(iRow,1) = iRow
iRow = iRow + 1
Wend
TheSheet.Range("A" & iRow).Select
ActiveSheet.Paste
ActiveWorkbook.Save
Next j
Workbooks(Workbooks.Count).Close
Next i
End If
End With
End Sub
--------------------------------------------------------------------------------------
对于Office2007的用户，Application.FileSearch不支持了，修改后的代码如下：
Sub test()
Dim i As Integer,iRow As Integer
Dim strPath,Filename,Search_Fullname As String
Dim TheSheet,CurrentSheet As Worksheet
Dim Coll_Docs As New Collection
Dim activeSheetName As String
iRow = 1
Set TheSheet = ActiveWorkbook.Worksheets("sheet1")
strPath = "D:/Macro/testtest"
Filename = "*.xls"
Set Coll_Docs = nothing
DocName = Dir(strPath & "/" & Filename)
Do Until DocName = ""
Coll_Docs.Add Item:=DocName
DocName = Dir
Loop
For i = Coll_Docs.Count To 1 Step -1
Search_Fullname = strPath & "/" & Coll_Docs(i)
Workbooks.Open (Search_Fullname)
For j = 1 To ActiveWorkbook.Worksheets.Count Step 1
If j = 1 Then
activeSheetName = "sheet" & j
Set CurrentSheet = ActiveWorkbook.Worksheets(activeSheetName)
End If
CurrentSheet.Activate
ActiveWorkbook.Worksheets(j).UsedRange.copy
TheSheet.Activate
While TheSheet.Range("a" & iRow).Value <> ""
TheSheet.Cells(iRow,1) = iRow
iRow = iRow + 1
Wend
TheSheet.Range("A" & iRow).Select
ActiveSheet.Paste
ActiveWorkbook.Save
Next j
Workbooks(Workbooks.Count).Close
Next i
End Sub
