excel - 仅从共享工作簿发送一次自动电子邮件

问题描述

我有代码可以在一天中的特定时间通过电子邮件将 Sheet1 的内容发送到分发列表。
这是一个共享工作簿，因此多个用户可以同时打开它。

该代码多次发送电子邮件，来自同一用户或多个用户作为电子邮件中的“发件人”。我假设是因为多个用户打开了文件。

我怎样才能只发送一次电子邮件？

Sheet1 在电子邮件正文中发送：

Sub Email()

    'Worksheets("Sheet1").Unprotect Password:="1"

    Dim ChartName1 As String
    Dim dataTable As String
    Dim rng As Range

    Set appOutlook = CreateObject("outlook.application")
    'create a new message
    Set Message = appOutlook.CreateItem(olMailItem)

    Set rng = Nothing
    On Error Resume Next
    'Only the visible cells in the selection
    'Set rng = Selection.SpecialCells(xlCellTypeVisible)
    'You can also use a fixed range if you want
    Set rng = Sheets("Sheet1").Range("A1:E11").SpecialCells(xlCellTypeVisible)
    On Error GoTo 0
  
    ChartName1 = Environ$("temp") & "\Chart1.gif"
    ActiveWorkbook.Worksheets("Sheet1").ChartObjects("Chart 1").Chart.Export _
    Filename:=ChartName1, FilterName:="GIF"
         
    With Message
        .Subject = " Files status " & Format(Date, "dd/mm/yyyy")
     
        .HTMLBody = "<span LANG=EN>" _
          & "<p class=style2><span LANG=EN><font FACE=Calibri SIZE=2>" _
          & "Dear all,<br ><br >Please see below the Open Files status for today : " _
          & "<br><BR>"
                
        .HTMLBody = .HTMLBody & rangetoHTML(rng) & "<br>"
          
        .HTMLBody = .HTMLBody & "<html><body><img src=" & "'" & ChartName1 & "'><Br><Br><Br/></body></html>"
             
        '  .HTMLBody = .HTMLBody & "<br><B>WEEKLY REPPORT:</B><br>" _
        '  & "<br>Best Regards,<br>Ed</font></span>"
            
        .To = "recipients here "
        .Cc = ""
                 
        .Display
        .Send
    End With
        
    Kill ChartName1
    Set OutMail = Nothing
    Set OutApp = Nothing

    'Worksheets("Sheet1").Protect Password:="1"
End Sub

    Dim fso As Object
    Dim ts As Object
    Dim TempFile As String
    Dim TempWB As Workbook

    TempFile = Environ$("temp") & "\" & Format(Now, "dd-mm-yy h-mm-ss") & ".htm"

    'Copy the range and create a new workbook to past the data in
    rng.Copy
    Set TempWB = Workbooks.Add(1)
    With TempWB.Sheets(1)
        .Cells(1).PasteSpecial Paste:=8
        .Cells(1).PasteSpecial xlPasteValues, , False, False
        .Cells(1).PasteSpecial xlPasteFormats, , False, False
        .Cells(1).Select
        Application.CutCopyMode = False
        On Error Resume Next
        .DrawingObjects.Visible = True
        .DrawingObjects.Delete
        On Error GoTo 0
    End With

    'Publish the sheet to a htm file
    With TempWB.PublishObjects.Add( _
         SourceType:=xlSourceRange, _
         Filename:=TempFile, _
         Sheet:=TempWB.Sheets(1).Name, _
         Source:=TempWB.Sheets(1).UsedRange.Address, _
         HtmlType:=xlHtmlStatic)
        .Publish (True)
    End With

    'Read all data from the htm file into RangetoHTML
    Set fso = CreateObject("Scripting.FileSystemObject")
    Set ts = fso.GetFile(TempFile).OpenAsTextStream(1, -2)
    rangetoHTML = ts.readall
    ts.Close
    rangetoHTML = Replace(rangetoHTML, "align=center x:publishsource=", _
                          "align=left x:publishsource=")

    'Close TempWB
    TempWB.Close savechanges:=False

    'Delete the htm file we used in this function
    Kill TempFile

    Set ts = Nothing
    Set fso = Nothing
    Set TempWB = Nothing

End Function
