VBA - 调整工作簿中的单元格范围以发送电子邮件

Question

我目前正在编写一段代码，每天发送一封电子邮件，其中包含作为附件的 excel 文件，以及将活动工作表嵌入到电子邮件正文中。我被要求找出是否有可能让 VBA 的嵌入式组件适应包括新的单元格范围。

所以，例如。在一张工作表上，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个工作表中，并且只将该部分嵌入到电子邮件中，是否可以不每次在 VBA 中编辑单元格范围？

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 = "recipient@test.com"
        .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

对此的任何建议将不胜感激。

我的回答可能看起来有点具体，但我认为你至少可以从中得到我想要的想法。

这就是我正在考虑的“主”表。在这个例子中，它从昨天开始就没有更新过（因此日期是9/12/2018）。

这是包含今天数据的工作表：

以下脚本将获取今天的数据，向其中添加"Date" 列，并为所有这些行填写今天的日期。然后它会将“今天”表中的数据复制到列表顶部的“主”表中。

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

上一个脚本添加"Date" 列之后的“今天”表中的数据：

这是插入今天数据后的“主”表：

---

最后，这是更新后的Mail_Sheet_Outlook_Body 子，它只从ActiveSheet（我之前将其称为“主”）中获取今天日期的数据。

现在它在A 列下工作，并在找不到包含今天日期的单元格时获取行号。然后它将rng 设置为从"A1" 到UsedRange 中的最后一列，再到具有今天日期的最后一行。

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
