A new forward or reply will have EntryID as null or null string until it's
saved.

There is no real good way to do what you want. You have to live with the
various hacks that are available.

Thank you for your reply, Ken. But both your suggestions will not work for
me:

1) ConversationIndex - yes, it's blank for a New item; but for an
existing
item, it always has a value no matter if you created an item by
Reply/Forward
an existing one, or opened an existing item by simple double clicking it.
2) "" or "FW:" - a) is not reliable (either the user can modify it at
any
time, or it may vary for different languages); b) again, cannot
distinguish
an item created by Reply/Forward from an item (may already has or FW:
in
the subject) opened by double clicking.

I may not be very clear. What I really want is the way to distinguish the
items created by Reply/Forward, "which are suppose to be sent out" (quoted
from my original post), from the items opened by double clicking, which
just
for viewing or printing or whatever purposes.
