I try to use BLAT dll from VFP 7.

I need to send a message with plain text body and attached
pdf file.
Unfortunately, BLAT adds message body as attachment to a message if I view message in Outlook Express.
Message body is empty.

My BLAT command line is :

body.txt -log smtplog.txt -subject "test blat" -noh2 -to mymail@corp.com -f mymail@corp.com -server mail.myhost.com
-attach mypdf.pdf -base64

How to force blat to send body.txt file or some string as message body, not as attachment ?
