CDO.Message.DataSource.Open() in .NET

[Zoury]

Hi folks! :O)

I need to take a email from a given mailbox and forward it to another
mailbox.

The code we had in VB 6 looked like this one :
'***
Dim objMsg As Object
Dim objFwd As Object

' get the mail we need to forward
Set objMsg = CreateObject("CDO.Message")
objMsg.DataSource.Open strMsgAddr, , 3, , , strUsername, strPassword

' create the forward mail, update the addresses
' and sends the mail
Set objFwd = objMsg.Forward
objFwd.To = strToAddr
objFwd.From = strFromAddr
objFwd.send
'***

since i need to convert this code into VB.NET code, I was wondering if CDO
was still the way to go ?

also, how would .NET (via CreateObject()) handles late-binding ? does it
create an interop-wrapper assembly at runtime ? is it slower than it was
before the "managed Era"...


and finally I's like to wish a Happy New Year to all you !! :OD

The SMTPMail class in the 1.1 framework is just a wrapper over CDO. There
is no reason not to simply continue to use CDO directly, especially since
your code does things that the wrapper doesn't let you get to. It won't be
any slower in the managed space. I don't see any reason to do late binding,
though. You can reference the CDO objects at design time and .Net will
create the CCW on the spot for you.

Hi,

Take a look at the mailmessage class.

Hi Nick!

The SMTPMail class in the 1.1 framework is just a wrapper over CDO.

Yeah I know. I've got 2 different CDO Libraries here CDO 1.21 and CDOEX...
do you happen to know which one was wrapped ? is CDO 1.21 library an
obsolete version ?

I don't see any reason to do late binding,
though. You can reference the CDO objects at design time and .Net will
create the CCW on the spot for you.

i guess they used late-binding to support further versions of CDO or to
avoid DLL hell somehow... ;O)


Thanks for your input!

Hi,

Sorry should have sent a link to the smtpmail class instead. It is
a managed wrapper for using cdo.
