Passing a parameter and starting Crystal Reports.

Hi All

I need to find out how to start Crystal Reports (Infoview) and pass a parameter from another application.

Basically, our core system which uses VB has an interface which the user can use to interegate a database. We want to put a button on the interface which would start Crystal Reports (or a viewer) and load in a parameter which the user would have selected on the initial interface.

Any ideas.

Best Regards

Roger
