Releasing COM Components Nenad Dobrilovic 10/10/2008 11:58:01 AM I have created programmatically a structure of root MAPIFolder, with subfolders and MailItems. Is it necessary to explicitly release all items (subfolders and mail items) or I can release only the root MAPIFolder? -- Nenad Dobrilovic

Re: Releasing COM Components "Ken Slovak - [MVP - Outlook]" <kenslovak[ at ]mvps.org> 10/10/2008 1:09:53 PM Best practice is to always release everything. Since you provide no information about your development language or platform or even the Outlook versions you're targeting it's impossible to say more. -- Ken Slovak [MVP - Outlook] http://www.slovaktech.com Author: Professional Programming Outlook 2007.

Re: Releasing COM Components "Ken Slovak - [MVP - Outlook]" <kenslovak[ at ]mvps.org> 10/10/2008 2:50:07 PM In that case in addition to setting all COM objects to null in the procedures where you declare them you should also use Marshal.ReleaseComObject() on them if you no longer need the objects or any other related objects. For example, if you have a locally declared Inspector object don't use Marshal.ReleaseComObject() on it if you still need other instances of that object anywhere in your code. Otherwise you get an RCW error when you try to refer to the Inspector in other parts of your code. -- Ken Slovak [MVP - Outlook] http://www.slovaktech.com Author: Professional Programming Outlook 2007.
