My app has data in SqlServer, front end in Access & reports in Crystal.

I know - why would I use Crystal & not Access' report generator, or use VB (& then RDC) instead of Access. Not my decisions, although I am going to discuss buying converter to change Access stuff to VB with boss when he is next in the office...

Meanwhile, how does one call a crystal report - & pass parameters for the query (? or the query) - from microsoft Access ?
