我已经耗尽了我的搜索功能,正在寻找解决方案。以下是我想要做的概述:
我遇到过一些ADO的引用,但我对此并不熟悉。
编辑:我找到了一个从已关闭文件导入数据的代码。我需要调整范围以返回变量结果。
Private Function GetValue(path, file, sheet, ref)
path = "C:\Users\crathbun\Desktop"
file = "test.xlsx"
sheet = "Sheet1"
ref = "A1:R30"
' Retrieves a value from a closed workbook
Dim arg As String
' Make sure the file exists
If Right(path, 1) <> "\" Then path = path & "\"
If Dir(path & file) = "" Then
GetValue = "File Not Found"
Exit Function
End If
' Create the argument
arg = "'" & path & "[" & file & "]" & sheet & "'!" & _
Range(ref).Range("A1").Address(, , xlR1C1)
' Execute an XLM macro
GetValue = ExecuteExcel4Macro(arg)
End Function
Sub TestGetValue()
path = "C:\Users\crathbun\Desktop"
file = "test"
sheet = "Sheet1"
Application.ScreenUpdating = False
For r = 1 To 30
For C = 1 To 18
a = Cells(r, C).Address
Cells(r, C) = GetValue(path, file, sheet, a)
Next C
Next r
Application.ScreenUpdating = True
End Sub
现在,我需要一个命令按钮或用户窗体,它会立即提示用户定义文件路径,并从该文件导入数据。
答案 0 :(得分:11)
我不介意在处理期间是否打开文件。我只是不希望用户必须单独打开文件。我只需要它们就可以选择或导航到所需的文件
这是一个基本代码。此代码要求用户选择两个文件,然后将相关工作表导入当前工作簿。我有两个选择。请选择:)
已经过测试
选项1(直接导入表格而不是复制到sheet1和2)
Option Explicit
Sub Sample()
Dim wb1 As Workbook, wb2 As Workbook
Dim Ret1, Ret2
Set wb1 = ActiveWorkbook
'~~> Get the first File
Ret1 = Application.GetOpenFilename("Excel Files (*.xls*), *.xls*", _
, "Please select first file")
If Ret1 = False Then Exit Sub
'~~> Get the 2nd File
Ret2 = Application.GetOpenFilename("Excel Files (*.xls*), *.xls*", _
, "Please select Second file")
If Ret2 = False Then Exit Sub
Set wb2 = Workbooks.Open(Ret1)
wb2.Sheets(1).Copy Before:=wb1.Sheets(1)
ActiveSheet.Name = "Blah Blah 1"
wb2.Close SaveChanges:=False
Set wb2 = Workbooks.Open(Ret2)
wb2.Sheets(1).Copy After:=wb1.Sheets(1)
ActiveSheet.Name = "Blah Blah 2"
wb2.Close SaveChanges:=False
Set wb2 = Nothing
Set wb1 = Nothing
End Sub
选项2(将表格内容导入第1页和第2页)
Option Explicit
Sub Sample()
Dim wb1 As Workbook, wb2 As Workbook
Dim Ret1, Ret2
Set wb1 = ActiveWorkbook
'~~> Get the first File
Ret1 = Application.GetOpenFilename("Excel Files (*.xls*), *.xls*", _
, "Please select first file")
If Ret1 = False Then Exit Sub
'~~> Get the 2nd File
Ret2 = Application.GetOpenFilename("Excel Files (*.xls*), *.xls*", _
, "Please select Second file")
If Ret2 = False Then Exit Sub
Set wb2 = Workbooks.Open(Ret1)
wb2.Sheets(1).Cells.Copy wb1.Sheets(1).Cells
wb2.Close SaveChanges:=False
Set wb2 = Workbooks.Open(Ret2)
wb2.Sheets(1).Cells.Copy wb1.Sheets(2).Cells
wb2.Close SaveChanges:=False
Set wb2 = Nothing
Set wb1 = Nothing
End Sub

下面的函数从已关闭的Excel文件中读取数据并将结果返回到数组中。它会丢失格式,公式等。您可能希望在主代码中调用isArrayEmpty函数(位于底部)来测试函数是否返回了某些内容。
Public Function getDataFromClosedExcelFile(parExcelFileName As String, parSheetName As String) As Variant
'see http://www.ozgrid.com/forum/showthread.php?t=19559
'returns an array (1 to nRows, 1 to nCols) which should be tested with isArrayEmpty in the calling function
Dim locConnection As New ADODB.Connection
Dim locRst As New ADODB.Recordset
Dim locConnectionString As String
Dim locQuery As String
Dim locCols As Variant
Dim locResult As Variant
Dim i As Long
Dim j As Long
On Error GoTo error_handler
locConnectionString = "Provider=Microsoft.Jet.OLEDB.4.0;" _
& "Data Source=" & parExcelFileName & ";" _
& "Extended Properties=""Excel 8.0;HDR=YES"";"
locQuery = "SELECT * FROM [" & parSheetName & "$]"
locConnection.Open ConnectionString:=locConnectionString
locRst.Open Source:=locQuery, ActiveConnection:=locConnection
If locRst.EOF Then 'Empty sheet or only one row
'''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''
'''''' FIX: an empty sheet returns "F1"
'''''' http://support.microsoft.com/kb/318373
'''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''
If locRst.Fields.Count = 1 And locRst.Fields(0).Name = "F1" Then Exit Function 'Empty sheet
ReDim locResult(1 To 1, 1 To locRst.Fields.Count) As Variant
For i = 1 To locRst.Fields.Count
locResult(1, i) = locRst.Fields(i - 1).Name
Next i
Else
locCols = locRst.GetRows
'''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''
'''''' FIX: an empty sheet returns "F1"
'''''' http://support.microsoft.com/kb/318373
'''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''
If locRst.Fields.Count = 1 And locRst.Fields(0).Name = "F1" And UBound(locCols, 2) = 0 And locCols(0, 0) = "" Then Exit Function 'Empty sheet
ReDim locResult(1 To UBound(locCols, 2) + 2, 1 To UBound(locCols, 1) + 1) As Variant
If locRst.Fields.Count <> UBound(locCols, 1) + 1 Then Exit Function 'Not supposed to happen
For j = 1 To UBound(locResult, 2)
locResult(1, j) = locRst.Fields(j - 1).Name
Next j
For i = 2 To UBound(locResult, 1)
For j = 1 To UBound(locResult, 2)
locResult(i, j) = locCols(j - 1, i - 2)
Next j
Next i
End If
locRst.Close
locConnection.Close
Set locRst = Nothing
Set locConnection = Nothing
getDataFromClosedExcelFile = locResult
Exit Function
error_handler:
'Wrong file name, sheet name, or other errors...
'Errors (#N/A, etc) on the sheet should be replaced by Null but should not raise an error
If locRst.State = ADODB.adStateOpen Then locRst.Close
If locConnection.State = ADODB.adStateOpen Then locConnection.Close
Set locRst = Nothing
Set locConnection = Nothing
End Function
Public Function isArrayEmpty(parArray As Variant) As Boolean
'Returns false if not an array or dynamic array that has not been initialised (ReDim) or has been erased (Erase)
If IsArray(parArray) = False Then isArrayEmpty = True
On Error Resume Next
If UBound(parArray) < LBound(parArray) Then isArrayEmpty = True: Exit Function Else: isArrayEmpty = False
End Function
样品使用:
Sub test()
Dim data As Variant
data = getDataFromClosedExcelFile("myFile.xls", "Sheet1")
If Not isArrayEmpty(data) Then
'Copies content on active sheet
ActiveSheet.Cells(1,1).Resize(UBound(data,1), UBound(data,2)) = data
End If
End Sub
