----------------------------Susan,
Have you attempted to use the MailMessage Class?
Dim myMessage As New Mail.MailMessage()
myMessage.To = myRecip
myMessage.From = myEmailAccount
myMessage.Body = myMessageText
myMessage.BodyFormat = Mail.MailFormat.Text
myMessage.Subject = "Check This Out!"
Mail.SmtpMail.Send(myMessage)
Will this work in your situation?
you cant do it that way in asp.net (that asp only). you need to import the namespace of the object and in most cases create an instance of it. i think that is what you are trying to do.
Oops, left out this piece:
Mail.SmtpMail.SmtpServer = "mySMTPServerName"
:-D
Hi,
CGGamer how to create an instance of it ...and how to import the namespace. please advice me...
netprofit i want to access the public folder of my outlook thru asp.net...
thanks,
susan
the .net framework is made up of classes and namespaces:
http://samples.gotdotnet.com/quickstart/aspplus/samples/classbrowser/vb/classbrowser.aspx
you can import a namespace such as:
<%@. Import Namespace="System.Data" %
and create an instance of an object from that namespace like:
dim objDR as new DataRow
what you are looking for is the System.IO Namespace. it allows you search through files on your computer and other things too. take a look at it in the link above.
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/cpref/html/frlrfSystemIOPathClassTopic.asp
i will try to find examples and post there links.
