What do schemas do

D

David Berry

The "schema" links you see in the code
(http://schemas.microsoft.com/cdo/configuration/) are URI's (Uniform
Resource Identifiers) and don't point to specific URL's. In other words they
are merely a namespace that are used to guarantee uniqueness. If you try to
go to any of these links you will find that they don't exist - hence you can
use them offline.

Here are some code examples:

Sending a TEXT Message

<%
Dim iMsg
Dim iConf
Dim Flds
Dim strText

' set the CDOSYS configuration fields to use port 25 on the SMTP server
Const cdoSendUsingPort = 2

set iMsg = CreateObject("CDO.Message")
set iConf = CreateObject("CDO.Configuration")

Set Flds = iConf.Fields

With Flds
..Item("http://schemas.microsoft.com/cdo/configuration/sendusing") =
cdoSendUsingPort
..Item("http://schemas.microsoft.com/cdo/configuration/smtpserver") =
"mail.mydomain.com"
..Item("http://schemas.microsoft.com/cdo/configuration/smtpconnectiontimeout")
= 10
..Update
End With

strText = "This is a sample email"
strText = strText & "sent from the Web Site"
strText = strText & "using CDOSys"

With iMsg
Set .Configuration = iConf
..To = "[email protected]"
..From = "[email protected]"
..Subject = "This is from a remote SMTP server."
..TextBody = strText
..Send
End With

Set iMsg = Nothing
Set iConf = Nothing
Set Flds = Nothing
%>

Sending an HTML formatted Message

<%
Dim iMsg
Dim iConf
Dim Flds
Dim strHTML

' set the CDOSYS configuration fields to use port 25 on the SMTP server
Const cdoSendUsingPort = 2

set iMsg = CreateObject("CDO.Message")
set iConf = CreateObject("CDO.Configuration")

Set Flds = iConf.Fields

With Flds
..Item("http://schemas.microsoft.com/cdo/configuration/sendusing") =
cdoSendUsingPort
..Item("http://schemas.microsoft.com/cdo/configuration/smtpserver") =
"mail.mydomain.com"
..Item("http://schemas.microsoft.com/cdo/configuration/smtpconnectiontimeout")
= 10
..Update
End With

strHTML = "<HTML>"
strHTML = strHTML & "<HEAD>"
strHTML = strHTML & "<BODY>"
strHTML = strHTML & "<b> Hello there! </b></br>"
strHTML = strHTML & "</BODY>"
strHTML = strHTML & "</HTML>"

With iMsg
Set .Configuration = iConf
..To = "[email protected]"
..From = "[email protected]"
..Subject = "This is from a remote SMTP server."
..HTMLBody = strHTML
..Send
End With

Set iMsg = Nothing
Set iConf = Nothing
Set Flds = Nothing
%>

Hi Thanks for replying
I am a bit confused, I don't understand "guarantee uniqueness" what
difference will it make if they where to be left out?

Thanks david
This seems complicated when something like jmail sends emails without all
of this. Is there a reason that cdosys is better than the send component of
jmail?
Thanks for bearing with me

I didn't say it was better. I personally like it but there are a lot of
different ways to send mail out there (JMail, CDOSYS, ASPEmail etc). It's a
preference thing. Use whichever one you like (as long as your web host
supports / offers it). if it does the job for you that's all that's
important.
