Replace Attachments with a Single Zip File

VB.NET code demonstrating how to add file attachments and then Zip them so that a single Zip file attachment is sent with the email. This only requires Chilkat Mail, and not Chilkat Zip.

        Dim success As Boolean

        ' Create a mailman object for sending email.
        Dim mailman As New Chilkat.MailMan()

        ' Any string argument automatically begins the 30-day trial.
        mailman.UnlockComponent("30-day trial")

        ' Set the SMTP server host.
        mailman.SmtpHost = "smtp.earthlink.net"

        ' Create a simple email with a Zip file attachment.
        Dim email As New Chilkat.Email()

        ' This email will have both a plain-text body and an HTML body.
        email.Body = "This is the plain-text alternative"
        email.AddHtmlAlternativeBody("<html><body><b><font color='red' size='+1'>This is bold red text.</font></b></html>")
        email.Subject = "This email has a file attachment."
        email.AddTo("Chilkat Support", "support@chilkatsoft.com")
        email.From = "Hello World <hello@chilkatsoft.com>"

        ' Add a file attachment.
        Dim contentType As String
        ' Returns the content-type of the attachment (determined by the file extension)
        ' This return value is for informational purposes only.
        contentType = email.AddFileAttachment("dude.gif")
        If contentType Is Nothing Then
            MessageBox.Show(email.LastErrorText)
            Return
        End If

        ' Add another file attachment.
        contentType = email.AddFileAttachment("dude2.gif")
        If contentType Is Nothing Then
            MessageBox.Show(email.LastErrorText)
            Return
        End If

        ' Replace the attachments with a single Zip archive that contains the files already attached.
        email.ZipAttachments("dudes.zip")

        ' Send email, the recipient will receive an email with a single attachment (dudes.zip)
        ' that contains 2 file: dude.gif and dude2.gif.
        success = mailman.SendEmail(email)
        If success Then
            MessageBox.Show("Sent mail with Zip attachment!")
        Else
            MessageBox.Show(mailman.LastErrorText)
        End If
