How to dynamically embed pdf file to crystal report?

Is there a way to do a dynamic ole insert of a pdf file into a crystal report based on a value coming from a SQL database?

For example, I have an application in .net, back-ended by a SQL 2008 database. The app. has a reporting subsystem which uses Crystal Reports to allow users to run pre-written reports (from stored procedures) by entering various inputs such as date ranges, etc.

What I want to do is allow the user to enter, say, an account开发者_高级运维 number which will then be passed to a stored procedure. The procedure will get the path to the correct PDF file and pass that to a Crystal Report. How do I get the PDF path to the OLE Object insert??

Is this making any sense??

Thanks for any help in advance.

do you have to use pdf? the idea of adding a pdf to a crystal report makes me feel dirty all over... If possible I would use rpt files as subreports. (note the reason it makes me pale quite so much is that I come from a *nix background and still think pdf should only be used for printing)
