Hi,

While i delete MailItem ( myMailItem.Delete() ) should i also call
ReleaseComObject,
and is it good idea to call Application.DoEvents after deleting item??

please review the code snippets:

................
...........
.............
mailItem.Delete();
Application.DoEvents();

Marshal.ReleaseComObject(mailItem);
mailItem = null;

......................
..............................


is it right way ???

TNX in advance;

You should always release objects when done with them. I'd put the nulling
of the object before calling to release the COM object though. I don't see
any need for DoEvents given the code you showed.

Thanks for replay,

After calling to Delete() method does pointer to mailItem still
remain?, suppose i call to Delete() in mailItem
that exists in Recycle folder.

TNX.

If an item is deleted and you still have a reference to that item it will
point to a null object but the object still needs to be released.

Thanx, great explanation.

Could u please suggest mr thr brst practise of releasing com objects in
..NET.
I develop addin for OL 2003 and using .net 2 C#. When and which objects
i should release ??

for example in newinspector event i get inspector object, after this i
perform casting to mailItem for example, and
let's say concernig to my business logic i should do nothing cause
this mailitem's named property is wrong or whatever, and i exit this
method (newinspector ) , my question is:

Do i need to release mailItem with Marshal.ReleaseComObject?? i guess
yes
and do i need to Release also inspector objec, that i get as parameter
in method?????

TNX in advance.

You should always release all your objects and not just let them go out of
scope. I usually just set them to null and only call
Marshal.ReleaseComObject on objects declared at the module level and objects
being released on the close of the last Explorer, just before
OnDisconnection would fire. I then call in my teardown code to the
GC.Collect() method and wait for pending finalizers.

Some people call Marshal.ReleaseComObject every time they release an object,
but that's more performance intensive. If the code will run for a while
longer I don't do that usually.
