Question

我在Item_Write事件处理程序中为会议请求设置取消检查，因为如果我在Item_Send中将取消设置为true，则会议窗口关闭。我正在尝试做的是提示用户他们有通常使用功能区中的自定义按钮处理的收件人（按钮详细信息对我的问题不重要）。无论如何，当我尝试取消Item_Write事件时，无论如何都会发送会议通知。无论我尝试什么，即使我将ref取消设置为true，我也无法阻止会议通知出去。如果我在Item_Send上取消，则窗口关闭，这不是用户想要的。我在这一点上唯一能想到的可能是requestDetailsRegion.SaveRequestDetailsToLocalOutlookItemProperties（），它将自定义表单区域字段属性保存到AppointmentItem上定义的自定义属性，触发Application_Item_Load事件，这不知何故提示Outlook发送会议邀请注意，好像它正在等待。我在Outlook 2010中运行它。请提前感谢。

以下是一些示例代码：

  void Item_Write(ref bool Cancel)        
 {    

            Cancel = CancelInvite(Cancel);                
 }

        private bool CancelInvite(bool Cancel)
        {

            Inspector activeInspector = Globals.ThisAddIn.Application.ActiveInspector();
            WindowFormRegionCollection formRegions = Globals.FormRegions[activeInspector];
            RequestDetailsFormRegion requestDetailsRegion = formRegions.RequestDetailsForm;


                // Add request form details to meeting item.
                requestDetailsRegion.SaveRequestDetailsToLocalOutlookItemProperties();

                // Checking if there's an incomplete form request pending submission
                if (requestDetailsRegion.txtFileName_Hidden.TextLength == 0 &&
                    appointmentItem != null && appointmentItem.MeetingStatus != OlMeetingStatus.olMeetingCanceled)
                {
                    Persons meetingRecipients = new Persons();



                    foreach (Outlook.Recipient recipient in appointmentItem.Recipients)
                        if (recipient.Address != activeInspector.Session.CurrentUser.Address)
                            meetingRecipients.Add(new MeetingRecipient(recipient));

                    if (meetingRecipients.ContainsSpecialRecipients)
                    {                           
                        CustomDialog customDialog = new CustomDialog();
                        customDialog.OkButtonText = messageBoxTextStatusOK;
                        customDialog.CancelButtonText = messageBoxTextStatusCancel;

                        DialogResult dialogResult = customDialog.ShowDialog();

                        if (dialogResult == DialogResult.Cancel)
                        {
                            Cancel = true;
                        }
                        else
                        {
                            Cancel = false;
                        }    

                        customDialog.Close();
                    }
                }                

            return Cancel;
        }

   public void SaveRequestDetailsToLocalOutlookItemProperties()
        {
            if (this.OutlookItem is Outlook.AppointmentItem)
            {
                Outlook.AppointmentItem appointmentItem = (Outlook.AppointmentItem)this.OutlookItem;

                // Checking if organizer already cancelled meeting. If so, then no need to update apppointment item properties.
                if (appointmentItem.MeetingStatus != Outlook.OlMeetingStatus.olMeetingCanceled)
                {

                    appointmentItem.ItemProperties[RequestSubmitted].Value = chkSubmitted.Checked; // Hidden 
                    appointmentItem.ItemProperties[Filename].Value = txtFileName_Hidden.Text; // Hidden

                    appointmentItem.ItemProperties[ReasonForVisit].Value = txtReason.Text;

   // SPARING SIMILAR LINES OF CODE

    ...
                    chkSaved.Checked = true;
                }
            }

您永远不会将（ref）Cancel参数设置为true

void Item_Write(ref bool Cancel)        
 {    

            this.cancelInviteResult = CancelInvite(Cancel);
            Cancel = this.cancelInviteResult; 
 }

即使我在Item_Write中设置了取消，也会发送会议通知
