Problem emailing PDF document from .net service

[=?Utf-8?B?U2FpIFZhamph?=]

Hi

I am trying to send a .pdf document as an email attachment using net.mail.
This email is being sent by a windows service application. After i receive
the email, and when i try to open the attachment, i get the following error
message...

"adobe reader could not open <filenamebecuas e it is either not a
suppported file type or because the file has been damaged(for example, it was
sent as an email attachment and wasn't correctly decoded)"

Here is a glimpse of the code doing the emailing..

Dim Mail_Message As MailMessage = New MailMessage(obj Email.MailFrom,
objEmail.MailTo )
Dim Server_Name As SmtpClient = New SmtpClient(Mail Server)
Dim Port_Number As Int32 = Convert.ToInt32 (MailServerPort Number)

With Mail_Message
.Body = Trim(objEmail.M essage)
.Subject = Trim(objEmail.S ubject)
.Priority = objEmail.Priori ty
.IsBodyHtml = True
.BodyEncoding = System.Text.Enc oding.Unicode

For Each oAttachment As Attachment In objEmail.Attach ments
.Attachments.Ad d(oAttachment) 'Here is where i am
attaching the file
Next

End With
Server_Name.Sen d(Mail_Message)

Are you also generating the PDF file in your program? Is this segment being
triggered by a filesystemwatch er?

It's possible that you're attempting to send the PDF before it has been
fully generated. Verify this by comparing the version that you've received
in your inbox and with the version of the file that you're trying to send in
a hex reader. My bet is that there are some critical bits in the latter part
of the PDF that are missing from the version that was emailed.

If this is indeed the problem, the solution here is simply to wait until the
file is done being written to. Try using the System.IO library to open the
file exclusively. If you can't, then the file isn't ready. Wait a few
milliseconds and try again until the PDF is done.

Cheers,
