Hi,
I am using Add-in Express for Office and .Net to develop an Outlook Addin.
I have added a ADX form. I want to access some properties of Outlook._Appointment object in that form. To access GlobalAppointmentID of the appointment i have added following property in AddInModule. 




        public string OutlookAppID
        {
            get
            {
                Outlook._Application app = Outlook._Application)HostApplication as Outlook._Application;

                return ((Outlook._AppointmentItem)app.ActiveInspector().CurrentItem).GlobalAppointmentID.ToString();
                
            }
        }


When i call this property i get an error
{System.AccessViolationException: Attempted to read or write protected memory. This is often an indication that other memory is corrupt.

Is there any other way to access Appointment object properties.

Thanks & Regards,
Sandeep Pulkundwar

Hi Sandeep,

I have sent you a letter. Please check your Inbox.

Please try to release COM objects and always check the value of properties for null (Nothing in VB).
