I believe OE is MAPI compliant. Check out Nigel Coates's MAPI class here in the Files section. You should be able to add attachments with it.

>If I click VFP Send button, a new Exchange client message is brings up. (Ok it is normal, because it is MAPI compliant)

>And now, the point!
>If I click on Word, Excel or NT Explorer Send button and select Mail... a new OE message brings up with an attachement. (The current file)

>But, as far as I know: Outlook Express 5 is not MAPI compliant. Then, Word or Excel how can it use? I thought that they use it via ShellExecute. But then, How they add an attachment programatically. AsI know, ShellExecute doesnot support to specify an attachment.
