In other words, how to implement the method GetTaskFromIntPtr in the code below? using Outlook = Microsoft.Office.Interop.Outlook; ... public void Method1(Outlook.TaskItem task) { IntPtr ptr = Marshal.GetIUnknownForObject(task.MAPIOBJECT); Outlook.TaskItem task1 = GetTaskFromIntPtr(ptr); // GetTaskFromIntPtr - ? } public Outlook.TaskItem GetTaskFromIntPtr(IntPtr) { ???? }

It is only sample. Actually, I'm trying to get updated TaskItem from TaskRequestUpdateItem. I assume, that TaskItem is in the olEmbeddeditem attachment of TaskRequestUpdateItem. The sequence of operations is: 1) Get the attachment of TaskRequestUpdateItem 2) Get the PR_ATTACH_DATA_OBJ of attachment (using Extended MAPI, IMAPIProp.OpenProperty) - so I have an IntPtr of the attachment object. I am almost assured that there is a TaskItem. But how to wrap it with Outlook.TaskItem interface I don't know. I need exactly OOM Outlook.TaskItem interface (not IMessage etc.).

Re: How to get Microsoft.Office.Interop.Outlook.TaskItem from the IUnknown (C#) "Godandag" <godandag[ at ]gmail.com> 4/4/2007 7:26:08 AM I know, this concrete problem (get TaskRequestUpdateItem attachment as TaskItem) can be solved like this: Outlook.TaskRequestUpdateItem item; .... Outlook.Attachments atts = item.Attachments; Outlook.Attachment att = atts[1]; att.SaveAsFile("F:\\111.oft"); Outlook.TaskItem task = (Outlook.TaskItem)ThisApplication.OlApp.CreateItemFromTemplate("F:\ \111.oft", Type.Missing); but I don't like this way for some reason. The way with wrapping IUnknown with the OOM interface is pleasant to me much more.

Re: How to get Microsoft.Office.Interop.Outlook.TaskItem from the IUnknown (C#) "Ken Slovak - [MVP - Outlook]" <kenslovak[ at ]mvps.org> 4/4/2007 1:43:37 PM That's the way I'd do it, using a save to file. You might want to post in the microsoft.public.win32.programmer.messaging group with this question. It's not strictly a MAPI question, which is what the group is for, but it's sufficiently close that the MAPI experts there may be able to help better than we can here. -- 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 "Godandag" <godandag[ at ]gmail.com> wrote in message news:1175671568.239006.287830[ at ]o5g2000hsb.googlegroups.com...
