That probably means you're not getting an AppointmentItem and probably
should be wrapping the reflection call in a try...catch block like I said
before.

Why not just cast the item to an AppointmentItem if it is one and use early
binding directly? You can test the Class property, which every Outlook item
has:

if (objItem = ReminderObject.Item.Class ==
Outlook.OlObjectClass.olAppointment)
{
// it's an appointment, continue
}
else
{
// if there's something you do for non-appointments
}

so strange,

it's ok with Subject property.
If I use below code instead of End Property, Dismiss() works fine.


string subject = (string)t.InvokeMember("Subject",

System.Reflection.BindingFlags.Public |

System.Reflection.BindingFlags.GetField |

System.Reflection.BindingFlags.GetProperty,
null,
objItem,
args);
