;  Add some attachments.
;  The AddFileAttachment method returns the value of the content-type it chose for the attachment.

;  If we save the email to a .eml, we can examine in a text editor.

    Exit
EndIf

;  We see the following in the e1.eml
;  Notice that Chilkat replaced the full path with just the filename.
;  The full local path is not part of the email that gets sent..

;  ...
;  --------------020807050607070004010609
;  Content-Type: image/jpeg; name="starfish.jpg"
;  Content-Transfer-Encoding: base64
;  Content-Disposition: attachment; filename="starfish.jpg"
;  
;  ...
;  --------------020807050607070004010609
;  Content-Type: application/pdf; name="fishing.pdf"
;  Content-Transfer-Encoding: base64
;  Content-Disposition: attachment; filename="fishing.pdf"
;  ...

;  Before sending, each filename can be changed within the email object.
;  For example:
$bSuccess = $oEmail.SetAttachmentFilename(0,"orange_starfish.jpg")
$bSuccess = $oEmail.SetAttachmentFilename(1,"tuna_fishing.pdf")

;  Look at the new MIME source of the email in a  text editor...
$bSuccess = $oEmail.SaveEml("qa_output/e2.eml")
If ($bSuccess = False) Then
    ConsoleWrite($oEmail.LastErrorText & @CRLF)
    ConsoleWrite("Failed to save .eml" & @CRLF)
    Exit
EndIf

;  You'll see this:

;  ...
;  --------------020807050607070004010609
;  Content-Type: image/jpeg; name="orange_starfish.jpg"

;  Content-Type: application/pdf; name="tuna_fishing.pdf"
;  Content-Transfer-Encoding: base64
;  Content-Disposition: attachment; filename="tuna_fishing.pdf"
;  ...

;  Send the email with the updated filenames..
$bSuccess = $oMailman.SendEmail($oEmail)
