vba当其他用户使用文件时打开excel [英] vba Open excel when File is used by another user

问题描述

这是我当前的代码

Public Sub OpenFiles()
    'Set LiveDealSheet file path
    'Check if LiveDealSheet is already open
    LDSP = "C:\Users\DCHEUNG\Desktop\Programing\LiveDealSheet.xlsm"
    IsOTF = IsWorkBookOpen(LDSP)

    'Set quick workbook shortcut
    Set TWB = ThisWorkbook
    If IsOTF = False Then
        Set LDS = Workbooks.Open(LDSP)
    Else
        Workbooks("LiveDealSheet.xlsm").Activate
        Set LDS = ActiveWorkbook
    End If
End Sub

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

    On Error Resume Next
    ff = FreeFile()
'i was just browsing through the online library and I found that "Open FileName For..." 
'have a lot of keywords. If I only want to open the file and copy stuff out to 
'another workbook do I use "Open FileName for Input Read As #ff"? 
'Then when I actually open the file in OpenFiles() I change 
'"Set LDS = Workbooks.Open(LDSP)" to "Set LDS = Workbooks.Open(LDSP) (ReadOnly)"
    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

我要打开的文件是一个共享文件。当没有使用，或当我已经打开文件，这段代码工作正常。但是每当其他用户已经打开一个文件，这个代码就会停止。

The file I am trying to open is a shared file. When no is it using, or when I already opened the file, this code works fine. But whenever another user already open a file, this code stops.

我知道一个事实，即使另一个用户使用该文件，我仍然可以在Read - 只有模式。所以我的问题是如何在这里包含该代码，希望没有弹出窗口询问您是否要以只读模式打开。

I know for a fact that even if another use is using the file, I can still open it in Read-Only mode. So my question is how to include that code in here, and hopefully without the pop-up asking if you want to open in Read-Only mode.

对不起，如果这是一个愚蠢的问题，但我完全不懂编码。

Sorry if this is a dumb question, but I am totally new to coding.

推荐答案

首先感谢您的输入。我已经通过一些试验和错误解决了我自己的问题。

First of all thanks for you input. I have solve the problem on my own with some trial and error.

将代码更改为以下

Public Sub OpenFiles()
    'Set LiveDealSheet file path
    'Check if LiveDealSheet is already open
    LDSP = "Z:\LiveDealSheet.xlsm"
    IsOTF = IsWorkBookOpen(LDSP)

    'Set quick workbook shortcut
    Set TWB = ThisWorkbook
    If IsOTF = False Then
        Set LDS = Workbooks.Open(LDSP)
        Debug.Print "Stage 1 Success"

更改了其他语句中的所有内容

changed everything in this else statement

    Else
        On Error Resume Next
        Set LDS = Workbooks("LiveDealSheet.xlsm")
        If LDS Is Nothing Then Workbooks.Open FileName:=LDSP, ReadOnly:=True, IgnoreReadOnlyRecommended:=True
    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
