Question

我需要帮助将几个已关闭的工作簿中的数据复制到使用VBA的主工作簿中，而无需打开它们。今天我使用函数Workbooks.open这样做，虽然我使用4-6个文件来复制数据，并且每个需要打开的文件 - 显着减慢了复制操作。

我需要帮助使用高效的VBA代码来复制数据，而无需打开每个文件。

这是我的代码示例：

Set x = Workbooks.Open("C:\Bel.xls")
    'Now, copoy what you want from x:
    x.Sheets("Daily Figures").Range("A13:j102").Copy
    'Now, paste to y worksheet
    y.Activate
    Sheets("Data - Daily").Range("N2").PasteSpecial
    'Close x:
    Application.CutCopyMode = False
    x.Close
    Sheets("sheet1").Range("M4") = Date

请帮忙提前谢谢，

试试这个。它在不打开源文件的情况下使用ADO工作：

Sub TransferData()
Dim sourceFile As Variant

Application.ScreenUpdating = False
Application.Calculation = xlCalculationManual

sourceFile = "C:\Bel.xls"

GetData sourceFile, "Daily Figures", "A13:j102", Sheets("Data - Daily").Range("N2"), False, False

Application.Calculation = xlCalculationAutomatic
Application.ScreenUpdating = True

End Sub

Public Sub GetData(sourceFile As Variant, SourceSheet As String, _
                   SourceRange As String, TargetRange As Range, Header As Boolean, UseHeaderRow As Boolean)
' 30-Dec-2007, working in Excel 2000-2007
' http://www.rondebruin.nl/ado.htm

Dim rsCon As Object
Dim rsData As Object
Dim szConnect As String
Dim szSQL As String
Dim lCount As Long

' Create the connection string.
If Header = False Then
    If Val(Application.Version) < 12 Then
        szConnect = "Provider=Microsoft.Jet.OLEDB.4.0;" & _
                    "Data Source=" & sourceFile & ";" & _
                    "Extended Properties=""Excel 8.0;HDR=No"";"
    Else
        szConnect = "Provider=Microsoft.ACE.OLEDB.12.0;" & _
                    "Data Source=" & sourceFile & ";" & _
                    "Extended Properties=""Excel 12.0;HDR=No"";"
    End If
Else
    If Val(Application.Version) < 12 Then
        szConnect = "Provider=Microsoft.Jet.OLEDB.4.0;" & _
                    "Data Source=" & sourceFile & ";" & _
                    "Extended Properties=""Excel 8.0;HDR=Yes"";"
    Else
        szConnect = "Provider=Microsoft.ACE.OLEDB.12.0;" & _
                    "Data Source=" & sourceFile & ";" & _
                    "Extended Properties=""Excel 12.0;HDR=Yes"";"
    End If
End If

If SourceSheet = "" Then
    ' workbook level name
    szSQL = "SELECT * FROM " & SourceRange$ & ";"
Else
    ' worksheet level name or range
    szSQL = "SELECT * FROM [" & SourceSheet$ & "$" & SourceRange$ & "];"
End If

Set rsCon = CreateObject("ADODB.Connection")
Set rsData = CreateObject("ADODB.Recordset")

rsCon.Open szConnect
rsData.Open szSQL, rsCon, 0, 1, 1

' Check to make sure we received data and copy the data
If Not rsData.EOF Then

    If Header = False Then
        TargetRange.Cells(1, 1).CopyFromRecordset rsData
    Else
        'Add the header cell in each column if the last argument is True
        If UseHeaderRow Then
            For lCount = 0 To rsData.Fields.Count - 1
