VBA - 在工作簿中调整单元格范围以发送电子邮件

Posted 2021-04-12

我正在编写一段代码，我发送的每日电子邮件中包含excel文件作为附件，并将活动工作表嵌入到电子邮件正文中。我被要求了解是否有可能让VBA的嵌入式组件适应新的单元格范围。

所以，例如。在一个工作表上，它将包含当天交易活动的数据。如果我想将第2天的交易数据添加到同一工作表中并且只将该部分嵌入到电子邮件中，那么每次在VBA中是否可以不编辑单元格范围？

我在下面附上了我的代码：

Sub Mail_Sheet_Outlook_Body()

    Dim rng As Range
    Dim OutApp As Object
    Dim OutMail As Object

    With Application
        .EnableEvents = False
        .ScreenUpdating = False
    End With

    Set rng = Nothing
    Set rng = ActiveSheet.UsedRange
    'You can also use a sheet name
    'Set rng = Sheets("YourSheet").UsedRange

    Set OutApp = CreateObject("Outlook.Application")
    Set OutMail = OutApp.CreateItem(0)

    On Error Resume Next
    With OutMail
        .to = "[e-mail]"
        .CC = ""
        .BCC = ""
        .Subject = "Trades Today" & Date
        .htmlBody = RangetoHTML(rng)
        .Attachments.Add ActiveWorkbook.FullName
        .Send                                    'or use .Display
    End With
    On Error GoTo 0

    With Application
        .EnableEvents = True
        .ScreenUpdating = True
    End With

    Set OutMail = Nothing
    Set OutApp = Nothing
End Sub

Function RangetoHTML(rng As Range)

    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"
    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

对此有任何建议将不胜感激。

答案

我的回答可能看起来有点具体但我认为从中你至少可以得到我想要的想法。

这就是我正在考虑的'主'表。在这个例子中，它从昨天起没有更新（因此日期是9/12/2018）。

这是包含今天数据的工作表：

以下脚本将采用今天的数据，向其添加"Date"列，并填写所有这些行的今天日期。然后它会将“今天”表格中的数据复制到列表顶部的“主”表格中。

Sub Data_Copy()

    Dim ws1 As Worksheet
    Set ws1 = ActiveSheet           'adjust as necessary

    Dim ws2 As Worksheet
    Set ws2 = sheets(ws1.index + 1) 'adjust as necessary

    Dim lastRow As Long
    lastRow = ws2.Range("A" & rows.count).End(xlUp).row

    If ws2.Range("A1").Value2 <> "Date" Then
        ws2.Columns(1).Insert Shift:=xlRight
        ws2.Range("A1").Value2 = "Date"

        ws2.Range("A2:A" & lastRow).value = Date
    End If

    ws2.rows("2:" & lastRow).copy
    ws1.rows(2).Insert Shift:=xlDown
    Application.CutCopyMode = False

End Sub

上一个脚本之后的'今天'表格中的数据添加了"Date"列：

在今天的数据插入其中后，这是'主'表：

最后，这里是更新的Mail_Sheet_Outlook_Body子程序，因此只从ActiveSheet（我之前称之为“主人”）获取今天日期的数据。

现在它在A列下工作，并且当它找不到该单元格中的今天的日期时获取行号。然后它设置rng从"A1"到UsedRange的最后一列，直到今天的日期的最后一行。

Sub Mail_Sheet_Outlook_Body()

    ...

    With Application
        .EnableEvents = False
        .ScreenUpdating = False
    End With


    'gets last row with today's date
    Dim i As Long
    For i = 2 To Range("A" & rows.count).End(xlUp).row
        If CDate(Range("A" & i).value) <> Date Then
            Exit For
        End If
    Next i

    'makes range out of today's cells
    Set rng = Range(Cells(1, "A"), Cells(i - 1, ActiveSheet.UsedRange.Columns.count))


    Set OutApp = CreateObject("Outlook.Application")
    Set OutMail = OutApp.CreateItem(0)

    ...

End Sub

Function RangetoHTML(rng As Range)
    ...
End Function
