Hi all.

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)
{
????
}

If you already have a task item why are you going through hoops to get
another instance of the same task item that way? Why not just copy the
passed task item or create a new one or use NameSpace.GetItemFromID() to
retrieve another instance of the task item if you can get its EntryID
property?

Hello Ken!
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.).

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.CreateItem FromTemplate("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.

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.
