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其状态的代码-无论它是否打开。即像IsWorkBookOpened("myWork.XL)
什么?
Answers:
尝试这个:
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已打开。对于这种情况,我更喜欢跳过布尔函数,而只返回工作簿。
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
Workbooks(sFile)
On Error Resume Next
代码,或者您在VBE中的“工具”-“选项”下设置了“在所有错误上都出错”。
On Error Resume Next
(因为wbReturn
是没有 Nothing
的,但包含一个错误),并写入真正的错误处理。请参阅:pastebin.com/u1LLgPa1
如果打开,它将在工作簿集合中:
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
我会这样:
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
如果要检查而不创建另一个Excel实例怎么办?
例如,我有一个Word宏(反复运行),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,则我不希望创建新实例。
我在这里建立了一个很好的答案: http //www.dbforums.com/microsoft-access/1022678-how-check-wether-excel-workbook-already-open-not-search-value.html
感谢MikeTheBike和kirankarnati
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
这一点比较容易理解:
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
