Waht is the fastest/bets? Outlook Object/CDO/Redemption/...?

[Pieter]

Hi,

I'm using a thight integration with Outlook 2003 (with an Exchange server)
in my VB.NET (2005) application.
Until now I'm using the Outlook Object Model, but it appears to be very
slow, and has some problems:
- doing a Move changes the ReceivedTime of the MailItem
- I can't use RichText in the MailItem.Body (only allows plain text or HTML)
- some other stuff like having to use small 'tricks' to show the default
signature in an email
- ...

So I'm looking to other ways to have an interactions with Outlook.
What I basicly need to do is:
- Move the currently selected mail to a specific folder, and write the data
of it to a database (subject, entryid, sender, recipients, attachments, ..)
- Create a new mail with a specific text, receiver, subject, attachements,
and once it is send move it to a specific folder and write the same data to
the database

These things actually do work, but especially the first one takes too much
time: on some clients more than 10 seconds!!
Is their a way to speed things up? using CDO or Redemption or ...? What are
the pros and cons of each way? Can they do what I need?

Any help our hints would be really aprpeciated!

Thanks a lot in advance,

Pieter


I did it now like this:

Public Function AddDocMails(ByVal DocList As Generic.List(Of clsDoc)) As
String
Dim oApp As Outlook.Application
Dim oExp As Outlook.Explorer
Dim oSel As Outlook.Selection ' You need a selection object for
getting the selection.
Dim oFolder As Outlook.MAPIFolder
Dim oItem As Outlook.MailItem

Dim intGood As Integer = 0
Dim intTotaal As Integer = 0

Try
oApp = New Outlook.Application
oExp = oApp.ActiveExplorer ' Get the ActiveExplorer.
oSel = oExp.Selection ' Get the selection.

Dim intX As Integer
Dim clsMail As clsDocMail
oFolder = oExp.CurrentFolder
intTotaal = oSel.Count

For intX = 1 To (oSel.Count)
Try

If oSel.Item(intX).Class = Outlook.OlObjectClass.olMail
Then
oItem = oSel.Item(intX)
clsMail = New clsDocMail(oItem, oFolder)
'save it!
clsMail.Save()
End If
Catch ex As Exception

Use CDO/Redemption if you need to work with large sets of items, especially
looping through collections. Use Redemption for bypassing the Object Model
Guard and to use some MAPI stuff, profile management and other functions not
handled by CDO. Stick with the OOM if you are primarily working with UI
related elements of Outlook items.

There's been other discussions lately around ReceivedTime changing; google
this group to see some threads.

To modify Rich Text, use the Word Object Model if Word is being used as the
editor, or the SafeInspector object with Redemption.
