電子メールにコード化されたカレンダー項目は作成日からソートされます - 予約日で並べ替える必要がある

Question

以下のコードは喜んで週のAppoinmentsで電子メールに移行しますが、実際の予定日ではなく、予定作成日から電子メールのカレンダーアイテムをリストします。予約日ごとに項目をリストする方法はありますか？ 私の謙虚な助けや提案をありがとう。 （私はこのコードにクレジットを取ることはできません。

Public Sub ListAppointments()
    On Error GoTo On_Error

    Dim Session As Outlook.NameSpace
    Dim Report As String
    Dim AppointmentsFolder As Outlook.Folder
    Dim currentItem As Object
    Dim currentAppointment As AppointmentItem
    Set Session = Application.Session

    Set AppointmentsFolder = Session.GetDefaultFolder(olFolderCalendar)

    For Each currentItem In AppointmentsFolder.Items
        If (currentItem.Class = olAppointment) Then
            Set currentAppointment = currentItem
            'get the week's appointments
        If currentAppointment.Start >= Now() And currentAppointment.Start <= Now() + 7 Then
                    If currentAppointment.AllDayEvent = False Then 'exclude all day events

               Call AddToReportIfNotBlank(Report, "Subject", currentAppointment.Subject)
               Call AddToReportIfNotBlank(Report, "Start", currentAppointment.Start)
               Call AddToReportIfNotBlank(Report, "End", currentAppointment.End)
               Call AddToReportIfNotBlank(Report, "Location", currentAppointment.Location)
               Report = Report & "-----------------------------------------------------"
               Report = Report & vbCrLf & vbCrLf

                    End If
                End If
        End If

    Next

    Call CreateReportAsEmail("List of Appointments", Report)

Exiting:
        Exit Sub
On_Error:
    MsgBox "error=" & Err.Number & " " & Err.Description
    Resume Exiting

End Sub

Private Function AddToReportIfNotBlank(Report As String, FieldName As String, FieldValue)
    AddToReportIfNotBlank = ""
    If (IsNull(FieldValue) Or FieldValue <> "") Then
        AddToReportIfNotBlank = FieldName & " : " & FieldValue & vbCrLf
        Report = Report & AddToReportIfNotBlank
    End If

End Function

'publish items to Outlook email
Public Sub CreateReportAsEmail(Title As String, Report As String)
    On Error GoTo On_Error

    Dim objNS As Outlook.NameSpace
    Dim objItem  As MailItem
    Dim objFolder As MAPIFolder

    Set objNS = Application.GetNamespace("MAPI") 'Application.Session
    Set objItem = Application.CreateItem(olMailItem)
    Set objFolder = objNS.GetDefaultFolder(olFolderInbox)

    With objItem
        .Subject = "This weeks appointments"
        .Body = Report
        .Display
    End With

Exiting:
        'Set Session = Nothing
        Exit Sub
On_Error:
    'MsgBox "error=" & Err.Number & " " & Err.Description
    Resume Exiting

End Sub

I have not reviewed your existing code although I did spot:

1. If you created a list of my appointments and omitted my all day meetings, I would be seriously displeased.
2. AddToReportIfNotBlank is not a function because it does not return a value.

With my solution you do not add appointments to Report as they are discovered. Instead they are added to an array of structures. Once all relevant appointments have been found, an array of indices into the array of structures is created and sorted by appointment date. Report is then built from the array of structures in index sequence. I hope that makes sense. Extra detail in the code.

My solution requires a structure. The type definition must be placed before any subroutines or functions.

Type typAppointment
  Start As Date
  AllDay As Boolean
  End As Date
  Subject As String
  Location As String
End Type

I need these variables in addition to yours:

  Dim AppointmentDtl() As typAppointment
  Dim InxADCrnt As Long
  Dim InxADCrntMax As Long
  Dim InxAppointmentSorted() As Long
  Dim InxSrtCrnt1 As Long
  Dim InxSrtCrnt2 As Long
  Dim Stg as String

This code prepares the array of structures for use. Place before the loop that looks for appointments:

  ReDim AppointmentDtl(1 To 100)
  ' * I avoid having too many ReDim Preserves because they
  '   involve creating a copy of the original array.
  ' * 100 appointments should be enough but the array will
  '   be resized if necessary.
  InxADCrntMax = 0      ' The current last used entry in AppointmentDtl

Delete your code:

        Call AddToReportIfNotBlank(Report, "Subject", currentAppointment.Subject)
        Call AddToReportIfNotBlank(Report, "Start", currentAppointment.Start)
        Call AddToReportIfNotBlank(Report, "End", currentAppointment.End)
        Call AddToReportIfNotBlank(Report, "Location", currentAppointment.Location)
        Report = Report & "-----------------------------------------------------"
        Report = Report & vbCrLf & vbCrLf

and replace with the following which stores the detail of the selected appointments in the structure. This code handles all day meetings as well as part day meetings:

        InxADCrntMax = InxADCrntMax + 1
        If InxADCrntMax > UBound(AppointmentDtl) Then
          ' Have filled array.  Add another 100 entries
          ReDim Preserve AppointmentDtl(1 To 100 + UBound(AppointmentDtl))
        End If
        AppointmentDtl(InxADCrntMax).Start = .Start
        If .AllDayEvent Then
          AppointmentDtl(InxADCrntMax).AllDay = True
        Else
          AppointmentDtl(InxADCrntMax).AllDay = False
          AppointmentDtl(InxADCrntMax).End = .End
        End If
        AppointmentDtl(InxADCrntMax).Subject = .Subject
        AppointmentDtl(InxADCrntMax).Location = .Location
      End If

Above Call CreateReportAsEmail("List of Appointments", Report) insert:

  ' Initialise index array as 1, 2, 3, 4, ...
  ReDim InxAppointmentSorted(1 To InxADCrntMax)
  For InxSrtCrnt1 = 1 To InxADCrntMax
    InxAppointmentSorted(InxSrtCrnt1) = InxSrtCrnt1
  Next

  ' Sort index array by AppointmentDtl(xxx).Start.
  ' This is not an efficient sort but it should be sufficient for your purposes.
  ' If not, I have a Shell Sort written in VBA although a Quick Sort
  ' is considered the best.
  InxADCrnt = 1
  Do While InxADCrnt < InxADCrntMax
    InxSrtCrnt1 = InxAppointmentSorted(InxADCrnt)
    InxSrtCrnt2 = InxAppointmentSorted(InxADCrnt + 1)
    If AppointmentDtl(InxSrtCrnt1).Start > AppointmentDtl(InxSrtCrnt2).Start Then
      InxAppointmentSorted(InxADCrnt) = InxSrtCrnt2
      InxAppointmentSorted(InxADCrnt + 1) = InxSrtCrnt1
      If InxADCrnt > 1 Then
        InxADCrnt = InxADCrnt - 1
      Else
        InxADCrnt = InxADCrnt + 1
      End If
    Else
      InxADCrnt = InxADCrnt + 1
    End If
  Loop

  ' InxAppointmentSorted() is now: 5, 20, 2, ... where appointment 5 is
  ' the earliest, appointment 20 the next and so on

  ' Process appointments in Start order
  For InxSrtCrnt1 = 1 To InxADCrntMax
    InxADCrnt = InxAppointmentSorted(InxSrtCrnt1)
    With AppointmentDtl(InxADCrnt)
      ' I have tested all other code on my calendar.  This code is untested.
      ' I have included all day meetings but you could easily restore the
      ' original approach.
      Call AddToReportIfNotBlank(Report, "Subject", .Subject)
      If .AllDay Then
        Stg = "All day " & Format(.Start, "dddd d mmm")
      Else
        ' Date formatted as "Friday 27 Jan". Use "dddd mmmm, d" if you
        ' prefer "Friday January, 27".  That is: "d" gives day of month
        ' with leading zero omitted. "dddd" gives full day of week. "mmm"
        ' gives three letter month.  "mmmm" gives full month.  "yy", if
        ' required, give two day year. "yyyy" gives four day year. Include
        ' spaces and punctuation as desired. 
        Stg = Format(.Start, "dddd d mmm") & _
              Format(.Start, " hh:mm") & " to " & _
              Format(.End, "hh:mm")
      End If
      Call AddToReportIfNotBlank(Report, "When", Stg)
      Call AddToReportIfNotBlank(Report, "Location", .Location)
      Report = Report & "-----------------------------------------------------"
      Report = Report & vbCrLf & vbCrLf
    End With
  Next

I hope I have included enough comments so all this makes sense. Do come back with questions is necessary.
