Opening a CAlendar Item with PR_Entry_ID

[PS]

Hi All

I have a question related to Outlook. I am accessing a MAPI folder
which contains meeting items. This is not the regular calender
standard folder but a different one which contains the same info. When
I access each item - i can get the PR_Entry_ID property for each item
in that folder.

Now I really want to use that value and open the item so that i can
then access other properties such as subject, start time, end time etc
since those are not availalbe in the regualr item.

I am open to using either Redemption to do so or also Outlook obejct
model whichever works better.

Following is the code i am currently doing:

RDOFolder folder =
rdoSession.Stores.DefaultStore.RootFolder.Folders.Item("AAA").Folders.Item("BBB");

foreach (object item in folder.Items)
{
object mapiObject = item.GetType().InvokeMember("MAPIOBJECT",
BindingFlags.Public | BindingFlags.GetField |
BindingFlags.GetProperty, null, item, new object[] { },
System.Globalization.CultureInfo.InvariantCulture);
}

iPrpID = 0x0FFF0102 //This contains the PR_Entry_ID Val;
header = rdoUtil.HrGetOneProp(mapiObject, iPrpID);
if (header != null)
row["PR_ENTRYID"] = rdoUtil.HrArrayToString(header);


So as you see from above - I get the PR_Entry_ID from above - then I
need to use this value and open the item to access some other
properties such as mentioned above.

Thanks

Why not use teh valu of teh EntryID property?

foreach (RDOMail item in folder.Items)
{
string entryid = mail.EntryID;

Secondly, there is no reason to use MAPIUtils.HrGetOnePorp, you can use
RDOMail.Fields[].

The reason I cant use entry id property is because this is not the
standard calendar folder. The value is stored in a named property.

But how do i acheive the second part - my question?

You use code like Dmitry showed:

foreach (RDOMail item in folder.Items)
{
string entryid = mail.EntryID;
string subject = mail.Subject;
string Body = mail.Body;
}

Why go through all the reflection and late binding and other complications
you have?

If your named property is a UserProperty then: mail.UserProperties[] is
what you want. If not then mail.Fields[] with a property tag matching the
one you used to create the named property. You can do that from
folder.GetIDsFromNames() to get the property tag.

What named property? You are reading the value of PR_ENTRYID.
Whether a message comes from a default folder or not, makes no difference.
