I have this great database that I use to send our clients invoices via email. There is just one problem that I keep having to face with some clients. Some clients won't accept the invoice that comes through email. Since the invoices are sent as an attachment using the SendObject commad, they are sent using a RTF extension. The client recieves the invoice and it is possible for anyone to change the document. This leave some Accounts Payable people very leary. I'm trying to find away to produce in Access a document that is unchangeable such as in PDF Format. Does anybody know how to accomplish this? The format will also need to comply with the Sendobject command. I've tried in the past to send OLE objects and didn't succeed.
