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. -- Ken Slovak [MVP - Outlook] http://www.slovaktech.com Author: Absolute Beginner's Guide to Microsoft Office Outlook 2003 Reminder Manager, Extended Reminders, Attachment Options http://www.slovaktech.com/products.htm "j" <Evgeny.Br[ at ]gmail.com> wrote in message news:1169572677.767918.228020[ at ]s48g2000cws.googlegroups.com...

Re: Delete MailItem "j" <Evgeny.Br[ at ]gmail.com> 1/24/2007 6:59:50 AM 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.

Re: Delete MailItem "Ken Slovak - [MVP - Outlook]" <kenslovak[ at ]mvps.org> 1/24/2007 3:02:27 PM 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. -- Ken Slovak [MVP - Outlook] http://www.slovaktech.com Author: Absolute Beginner's Guide to Microsoft Office Outlook 2003 Reminder Manager, Extended Reminders, Attachment Options http://www.slovaktech.com/products.htm "j" <Evgeny.Br[ at ]gmail.com> wrote in message news:1169621990.708314.205840[ at ]q2g2000cwa.googlegroups.com...

Re: Delete MailItem "j" <Evgeny.Br[ at ]gmail.com> 1/24/2007 9:58:33 PM 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.

Re: Delete MailItem "Ken Slovak - [MVP - Outlook]" <kenslovak[ at ]mvps.org> 1/25/2007 6:47:21 PM 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. -- Ken Slovak [MVP - Outlook] http://www.slovaktech.com Author: Absolute Beginner's Guide to Microsoft Office Outlook 2003 Reminder Manager, Extended Reminders, Attachment Options http://www.slovaktech.com/products.htm "j" <Evgeny.Br[ at ]gmail.com> wrote in message news:1169675913.037123.127460[ at ]a75g2000cwd.googlegroups.com...
