检测 Excel 工作簿是否已打开 [关闭]

Question

在 VBA 中，我以编程方式打开了一个名为“myWork.XL”的 MS Excel 文件。

现在我想要一个可以告诉我它的状态的代码——它是否打开。 IE。 IsWorkBookOpened("myWork.XL) 之类的东西？

Answer 1

试试这个：

Option Explicit

Sub Sample()
    Dim Ret

    Ret = IsWorkBookOpen("C:\myWork.xlsx")

    If Ret = True Then
        MsgBox "File is open"
    Else
        MsgBox "File is Closed"
    End If
End Sub

Function IsWorkBookOpen(FileName As String)
    Dim ff As Long, ErrNo As Long

    On Error Resume Next
    ff = FreeFile()
    Open FileName For Input Lock Read As #ff
    Close ff
    ErrNo = Err
    On Error GoTo 0

    Select Case ErrNo
    Case 0:    IsWorkBookOpen = False
    Case 70:   IsWorkBookOpen = True
    Case Else: Error ErrNo
    End Select
End Function

对于我的应用程序，我通常希望使用工作簿，而不仅仅是确定它是否打开。对于这种情况，我更喜欢跳过布尔函数，只返回工作簿。

Sub test()

    Dim wb As Workbook

    Set wb = GetWorkbook("C:\Users\dick\Dropbox\Excel\Hoops.xls")

    If Not wb Is Nothing Then
        Debug.Print wb.Name
    End If

End Sub

Public Function GetWorkbook(ByVal sFullName As String) As Workbook

    Dim sFile As String
    Dim wbReturn As Workbook

    sFile = Dir(sFullName)

    On Error Resume Next
        Set wbReturn = Workbooks(sFile)

        If wbReturn Is Nothing Then
            Set wbReturn = Workbooks.Open(sFullName)
        End If
    On Error GoTo 0

    Set GetWorkbook = wbReturn

End Function

如果打开，它将位于 Workbooks 集合中：

Function BookOpen(strBookName As String) As Boolean
    Dim oBk As Workbook
    On Error Resume Next
    Set oBk = Workbooks(strBookName)
    On Error GoTo 0
    If oBk Is Nothing Then
        BookOpen = False
    Else
        BookOpen = True
    End If
End Function

Sub testbook()
    Dim strBookName As String
    strBookName = "myWork.xls"
    If BookOpen(strBookName) Then
        MsgBox strBookName & " is open", vbOKOnly + vbInformation
    Else
        MsgBox strBookName & " is NOT open", vbOKOnly + vbExclamation
    End If
End Sub

我会选择这个：

Public Function FileInUse(sFileName) As Boolean
    On Error Resume Next
    Open sFileName For Binary Access Read Lock Read As #1
    Close #1
    FileInUse = IIf(Err.Number > 0, True, False)
    On Error GoTo 0
End Function

作为 sFileName，您必须提供文件的直接路径，例如：

Sub Test_Sub()
    myFilePath = "C:\Users\UserName\Desktop\example.xlsx"
    If FileInUse(myFilePath) Then
        MsgBox "File is Opened"
    Else
        MsgBox "File is Closed"
    End If
End Sub

如果您想在不创建另一个 Excel 实例的情况下进行检查怎么​​办？

例如，我有一个 Word 宏（重复运行），它需要从 Excel 电子表格中提取数据。如果电子表格已在现有 Excel 实例中打开，我不希望创建新实例。

Function WorkbookOpen(strWorkBookName As String) As Boolean
    'Returns TRUE if the workbook is open
    Dim oXL As Excel.Application
    Dim oBk As Workbook

    On Error Resume Next
    Set oXL = GetObject(, "Excel.Application")
    If Err.Number <> 0 Then
        'Excel is NOT open, so the workbook cannot be open
        Err.Clear
        WorkbookOpen = False
    Else
        'Excel is open, check if workbook is open
        Set oBk = oXL.Workbooks(strWorkBookName)
        If oBk Is Nothing Then
            WorkbookOpen = False
        Else
            WorkbookOpen = True
            Set oBk = Nothing
        End If
    End If
    Set oXL = Nothing
End Function

Sub testWorkbookOpen()
    Dim strBookName As String
    strBookName = "myWork.xls"
    If WorkbookOpen(strBookName) Then
        msgbox strBookName & " is open", vbOKOnly + vbInformation
    Else
        msgbox strBookName & " is NOT open", vbOKOnly + vbExclamation
    End If
End Sub

这个比较容易理解：

Dim location As String
Dim wbk As Workbook

location = "c:\excel.xls"

Set wbk = Workbooks.Open(location)

'Check to see if file is already open
If wbk.ReadOnly Then
  ActiveWorkbook.Close
    MsgBox "Cannot update the excelsheet, someone currently using file. Please try again later."
    Exit Sub
End If
