ASP Email Attachment Problem

[mturner64]

I am working on a simple email application and I am able to send mail successfully through but I cannot get the "fileUpload tool", to attach any files. Each time I try any different attachment code I get errors and the mail will not send. My code is below: Thank you.

Imports System.Web.Mail
Partial Class _Default
    Inherits System.Web.UI.Page
 
    Protected Sub btnSend_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnSend.Click
        Dim emailBody As String = txtBody.Text
        Dim emailMessage As New Mail.MailMessage()
 
        emailMessage.BodyFormat = Mail.MailFormat.Text
        emailMessage.To = txtTo.Text
        emailMessage.From = "[e-mail]"
        emailMessage.Subject = txtSubject.Text
        emailMessage.Body = txtBody.Text
        Label1.Text = "Your message has been sent!"
 
        emailMessage.Attachments.Add(New MailAttachment(AttachmentFile.PostedFile.InputStream, AttachmentFile.FileName))
 
        SmtpMail.SmtpServer = "webmail.student.sosu.edu"
        SmtpMail.Send(emailMessage)
 
 
    End Sub

Well, before I run the program it gives this error.

"Error 3 Type 'Attachment' is not defined. "

Referring to the word Attachment following the word New

If I add the word Mail on the front of attachment it throws errors stating the "AttachmentFile" is not declared

[DrBunchman]

I think it's just looking for a string containing the path and filename of your attachment.

Have you tried putting that in?

Could you please share an example? I have tried about 15 different alternatives and none have seemed to work! My brain is getting a bit fuzzy, lol.

Does the following work?

emailMessage.Attachments.Add(New System.Net.Mail.Attachment(AttachmentFile.FileName))

Dr B

Edit - actually you'll need to use the full file path of the attachment rather than the FileName property.

Does the following work?

emailMessage.Attachments.Add(New System.Net.Mail.Attachment(AttachmentFile.FileName))

Dr B

No, error says "AttachmentFile" is not declared.

Where is the file stored that you wish to attach? Is it automatically selected by your app or does your user select it from a dialog box?

The user selects it from the fileUpload control (browse button).

I could be wrong about this but I would have thought that the user must upload the file to your server before you can send it. Does your code do this?

I do not believe so.

I do not believe so.

Using the following different code:

Dim attachFile As New MailAttachment(txtAttachmentPath.PostedFile.InputStream.ToString)
        emailMessage.Attachments.Add(attachFile)

Causes no pre-build errors but when I run the application this error occurs:

Server Error in '/proj02' Application.
--------------------------------------------------------------------------------

Invalid mail attachment 'System.Web.HttpInputStream'.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Can you try to upload the file to the server first then add the uploaded file as an attachment.

This tutorial will help you to sort out the uploading bit.

Let me know how it goes.
