vb.net - 如何用vb在outlook中创建约会？

Question

我有一个 winforms 应用程序，我正在尝试创建一个方法来创建新的 Outlook 约会。我正在使用以下代码，但在对象newAppointment的创建部分标记了一个错误。

Private Sub AddAppointment()
    Dim newAppointment As Outlook.AppointmentItem = Me.Application.CreateItem _
         (Outlook.OlItemType.olAppointmentItem)
    Try
        With newAppointment
            .Start = Date.Now.AddHours(2)
            .End = Date.Now.AddHours(3)
            .Location = "ConferenceRoom #2345"
            .Body = _
                "We will discuss progress on the group project."
            .Subject = "Group Project"
            .AllDayEvent = False
            .Recipients.Add("Roger Harui")
            Dim sentTo As Outlook.Recipients = .Recipients
            Dim sentInvite As Outlook.Recipient
            sentInvite = sentTo.Add("Holly Holt")
            sentInvite.Type = Outlook.OlMeetingRecipientType.olRequired
            sentInvite = sentTo.Add("David Junca")
            sentInvite.Type = Outlook.OlMeetingRecipientType.olOptional
            sentTo.ResolveAll()
            .Save()
            .Display(True)
        End With
    Catch ex As Exception
        MessageBox.Show("The following error occurred: " & _
            ex.Message)
    End Tryenter code here
End Sub

需要访问 Outlook Application 对象，因为您自己的 Application 没有合适的 CreateItem 方法:

大致如下:

Imports Microsoft.Office.Interop

....

Private Sub AddAppointment()
    '--- Check if Outlook is already up and running
    If Process.GetProcessesByName("outlook").Count > 0 Then
        '--- all ready ---
    Else
        '--- start Outlook ---
        Process.Start("outlook")
        '--- more elaborate wait might be a good idea here ---
        System.Threading.Thread.Sleep(500)
    End If

    '--- initialize required Application object ---
    '--- assuming it is not available as variable already ---
    Dim objOutlook As Outlook.Application
    objOutlook = CreateObject("Outlook.Application")

    Dim newAppointment As Outlook.AppointmentItem =
        objOutlook.CreateItem(Outlook.OlItemType.olAppointmentItem)
    Try
        With newAppointment
            .Start = Date.Now.AddHours(2)
            .End = Date.Now.AddHours(3)
            .Location = "ConferenceRoom #2345"
            .Body = "We will discuss progress on the group project."
            .Subject = "Group Project"
            .AllDayEvent = False
            .Recipients.Add("Roger Harui")
            Dim sentTo As Outlook.Recipients = .Recipients
            Dim sentInvite As Outlook.Recipient
            sentInvite = sentTo.Add("Holly Holt")
            sentInvite.Type = Outlook.OlMeetingRecipientType.olRequired
            sentInvite = sentTo.Add("David Junca")
            sentInvite.Type = Outlook.OlMeetingRecipientType.olOptional
            sentTo.ResolveAll()
            .Save()
            .Display(True)
        End With
    Catch ex As Exception
        MessageBox.Show("The following error occurred: " & ex.Message)
    End Try
End Sub
