Oracle Forms

Hi,
I am using the mailto as below

web.show_document('mailto:mmathias@gtsuae.com&subject='||lv_subject||'%20&body=Date:%20%'||:SYSTEM.CURRENT_DATETIME||'%0A%0APlease find the generated file in pdf format','blank');

I am sucessful in generating the mail to, subject and the mail body but is there a way by which i can automatically attach a mail attachment (could be a pdf file just generated before this code executes.

or does someone have a better idea as my requirement is that as and when a transaction is complete a user will select a check box and execute a button (send mail), for the same transaction i want to generate a PDF file ad send it to the selected group, but i do not want this as a silent background process (it should open a new outlook window) with the generated report as an attachment.

I can generate the pdf file and also open a new outlook form but the attachment is the issue.

Regards
Melvin
