使用VBA在Excel中搜索約會

Question

我正在嘗試編寫一個腳本，以讀取我的Excel工作表，並將日期與Outlook中的約會日期進行比較。

我不知道為什么我的代碼沒有找到任何OLAppointment項來將其日期與工作表上的dte進行比較...

見下面的代碼

Public Function CheckAppointment(ByVal argCheckDate As Date) As Boolean

    Dim oApp As Object
    Dim oNameSpace As Object
    Dim oApptItem As Object
    Dim oFolder As Object
    Dim oMeetingoApptItem As Object
    Dim oObject As Object
    On Error Resume Next

    Set oApp = GetObject(, "Outlook.Application")
    If oApp Is Nothing Then Set oApp = CreateObject("Outlook.Application")

    Set oNameSpace = oApp.GetNamespace("MAPI")
    Set oFolder = oNameSpace.Session.GetDefaultFolder(9).Folders("aa")
    CheckAppointment = False
    For Each oObject In oFolder.Items
    MsgBox oObject
    If (oObject.Class = OLAppointment) Then
      Set oApptItem = oObject
        If oApptItem.Start = argCheckDate Then
            CheckAppointment = True
        End If
      End If
    Next oObject

    Set oApp = Nothing
    Set oNameSpace = Nothing
    Set oApptItem = Nothing
    Set oFolder = Nothing
    Set oObject = Nothing

End Function

Public Sub Driver()

    Dim dtCheck As Date
    Dim sbCheck As String

    dtCheck = DateValue("23/11/2013") + TimeValue("09:00:00")


    If CheckAppointment(dtCheck) Then
        MsgBox "Appointment found", vbOKOnly + vbInformation
    Else
        MsgBox "Appointment not found", vbOKOnly + vbExclamation
    End If

End Sub

我在2013年11月23日的日歷“ aa”上創建了一個約會，但是當我嘗試使用宏對其進行搜索時，總是給我“未找到約會”。 我還嘗試用“ Msgbox”顯示通過以下方式找到的約會的屬性：

Set oFolder = oNameSpace.Session.GetDefaultFolder(9).Folders("aa")
CheckAppointment = False
For Each oObject In oFolder.Items
MsgBox oObject.Subject

但無論如何都不要走：\\

抱歉我的英語不好。

問題是您沒有定義什么是OLAppointment 。 由於這是Excel中的宏，因此您需要定義Outlook內部常量。

Public Function CheckAppointment(ByVal argCheckDate As Date) As Boolean

    Const olAppointment = 26 ' <== Added this line and your code worked.
    Dim oApp As Object
    Dim oNameSpace As Object
    Dim oApptItem As Object
    Dim oFolder As Object
    Dim oMeetingoApptItem As Object
    Dim oObject As Object
    On Error Resume Next ' No appointment was found since you have this line and olAppointmnet wasn't defined.

    Set oApp = GetObject(, "Outlook.Application")
    If oApp Is Nothing Then Set oApp = CreateObject("Outlook.Application")

    Set oNameSpace = oApp.GetNamespace("MAPI")
    Set oFolder = oNameSpace.Session.GetDefaultFolder(9).Folders("aa")
    CheckAppointment = False
    For Each oObject In oFolder.Items
        MsgBox oObject
        If (oObject.Class = olAppointment) Then ' <== This is why you need to define it first
            Set oApptItem = oObject
            If oApptItem.Start = argCheckDate Then
                CheckAppointment = True
                Exit For ' <== Added this exit for loop to improve performance
            End If
        End If
    Next oObject

    Set oApp = Nothing
    Set oNameSpace = Nothing
    Set oApptItem = Nothing
    Set oFolder = Nothing
    Set oObject = Nothing
End Function

Public Sub Driver()
    Dim dtCheck As Date
    Dim sbCheck As String

    dtCheck = DateValue("4/11/2013") + TimeValue("09:00:00")
    If CheckAppointment(dtCheck) Then
        MsgBox "Appointment found", vbOKOnly + vbInformation
    Else
        MsgBox "Appointment not found", vbOKOnly + vbExclamation
    End If
End Sub

您的代碼可以正常工作，並使用默認Calendar下名為aa的Calendar進行測試。
