使用VBA在Excel中搜索约会

Question

我正在尝试编写一个脚本，以读取我的Excel工作表，并将日期与Outlook中的约会日期进行比较。

我不知道为什么我的代码没有找到任何OLAppointment项来将其日期与工作表上的dte进行比较...

见下面的代码

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日的日历“ aa”上创建了一个约会，但是当我尝试使用宏对其进行搜索时，总是给我“未找到约会”。 我还尝试用“ Msgbox”显示通过以下方式找到的约会的属性：

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

但无论如何都不要走：\\

抱歉我的英语不好。

问题是您没有定义什么是OLAppointment 。 由于这是Excel中的宏，因此您需要定义Outlook内部常量。

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

您的代码可以正常工作，并使用默认Calendar下名为aa的Calendar进行测试。
