I am writing an application to extract data to an access table, say A. I want to allow the user to press a button and then crystal report (designer) will be pop up for them to define the layout.

1. How I can start the CR designer by pressing a button?
2. How I can specify the data file location and filename?
3. If the report does not exist before, can I still run the designer with the data file specified?

Thank you if anybody can help me on these!
