I'm somewhat new to VB.Net but I've programmed ASP.Net and VB6 before.
Anyway, I'm trying to send a bunch of emails from a listbox and I get an
error. Here's the exception message:
"Could not access 'CDO.Message' object."

I don't know what could be causing it. If someone could shed some light
I'd appreciate it. Here's my code:

Code:

Dim MailMsg As New System.Web.Mail.MailMessage
Dim mServer As System.Web.Mail.SmtpMail

MailMsg.Subject = "Message Subject"
MailMsg.Body = "Message Body."
MailMsg.From = "fromaddress@... <mailto:fromaddress@...>
"
MailMsg.BodyFormat = Web.Mail.MailFormat.Html
mServer.SmtpServer = "smtpserver.com"

For i = 0 To lstEmails.Items.Count - 1
lstEmails.SelectedIndex = i
MailMsg.To = lstEmails.SelectedValue
mServer.Send(MailMsg)
Next

This should work in you mailling application!!!

Code:

Dim ErrLog As String
Dim MailMsg As New System.Web.Mail.MailMessage
Dim mServer As System.Web.Mail.SmtpMail

With MailMsg
.Subject = "Message Subject"
.Body = "Message Body."
.From = "fromaddress@..."
.BodyFormat = Web.Mail.MailFormat.Html
mServer.SmtpServer = "smtpserver.com"

For i = 0 To lstEmails.Items.Count - 1
lstEmails.SelectedIndex = i
.To = lstEmails.SelectedValue
Try
mServer.Send(MailMsg)
Catch EX As Exception
ErrLog = ErrLog & EX.message & "; "
End Try
Next
End with

'Go ahead and display your ErrLog here to the user if any

NOTE:
I put the mServer.Send method in a try block in case there's any of the
lstEmails values that's not in email address format. That could generate an
error and stop the application from sending the mail to others.

Another thing I think was the problem in your application is the introduction
of the <mailto:""> tag in your .From value. As much as I know, that is not
necessary.

I hope this helps.
