我想知道是否有人知道如何使用 VBA 从封闭的工作簿中引用单元格。

我知道如何使用 ADO 和 SQL 引用一系列单元格，但我不知道如何为特定单元格创建 SQL 查询。

在浏览互联网时，我遇到了一些使用“ExecuteExcel4Macro”的代码，但我找不到该函数/命令的任何真实文档。事实上，MSDN 网站上关于这个命令的文档是垃圾和模糊的，坦率地说，完全没有帮助。

无论如何，我离题了；理想情况下，我想从外部工作簿调用一个单元格，而不必打开所述工作簿。我试图开始工作的代码如下：

    Sub update_overview() 

Dim wbPath As String 
Dim wbName As String 
Dim wsName As String 
Dim cellRef As String 
Dim data As Variant 

wbPath = "C:\examplepath\" 
wbName = "Core (N)i.xls" 
wsName = "Sheet1" 
cellRef = "C5" 

'data = GetData(wbPath, wbName, wsName, cellRef) 

ThisWorkbook.Activate 
Sheets("Overview").Select 
With Selection 
ActiveSheet.Range("C5").Clear 
ActiveSheet.Range("C5").Select 
ActiveCell = GetData(wbPath, wbName, wsName, cellRef) 
End With 


End Sub 


Private Function GetData(ByVal wbPath As String, _ 
wbName As String, wsName As String, cellRef As String) As Variant 

Dim arg As String 

GetData = "" 
arg = "'" & wbPath & "[" & wbName & "]" & _ 
wsName & "'!" & Range(cellRef).Address(True, True, xlR1C1) 

GetData = ExecuteExcel4Macro(arg) 
End Function

当我运行宏时，它唯一返回的是#REF

我也试过：

Sub Sample() 
Dim wbPath As String, wbName As String 
Dim wsName As String, cellRef As String 
Dim Ret As String 

'wbPath = "C:\Documents and Settings\Siddharth Rout\Desktop\" 
wbPath = "C:\Users\my.name\Desktop\" 

wbName = "QOS DGL stuff.xls" 
wsName = "ACL" 
cellRef = "C3" 

Ret = "'" & wbPath & "[" & wbName & "]" & _ 
wsName & "'!" & Range(cellRef).Address(True, True, -4150) 

MsgBox ExecuteExcel4Macro(Ret) 
End Sub

当代码到达 MsgBox 时，我收到类型不匹配错误。如果我摆脱 msgbox 命令并尝试继续粘贴到单元格

ThisWorkbook.Activate 
Sheets("Overview").Select 
With Selection 
ActiveSheet.Range("C5").Clear 
ActiveSheet.Range("C5").Select 
ActiveCell = ExecuteExcel4Macro(Ret)

我仍然得到#REF！错误

谁能告诉我：1）这是最好的技术吗？2）我的代码有什么问题？并且，3) 是否有更好的方法可以使用 ADO 或 DOA 或我不知道的技术从外部工作簿中引用单个单元格。

还有人知道有关如何使用 ExecuteExcel4Macro 函数的任何详细文档。

请帮忙; 谢谢

仅供参考，我在 excel 2003 上

你可以尝试这样的事情：

arg = "='" & wbPath & "[" & wbName & "]" & wsName & "'!" & cellRef

Sub Test()

Dim wbName As String
Dim wbPath As String
Dim wsName As String
Dim cellRef As String
Dim calcState As Long

calcState = Application.Calculation

wbPath = "C:\users\david_zemens\"
wbName = "a report.xlsx"
wsName = "Sheet1"
cellRef = Range("B2").Address

Dim arg As String
arg = "='" & wbPath & "[" & wbName & "]" & wsName & "'!" & cellRef 'Range(cellRef).Address(True, True, xlR1C1)

Application.Calculation = xlCalculationManual
Application.DisplayAlerts = False
ActiveCell.Value = arg
ActiveCell.Value = ActiveCell.Value 'essentially a paste/values over the formula.
Application.DisplayAlerts = True
Application.Calculation = calcState



End Sub
