Crystal Report issue

Question

I am New to crystal reports. I would need a help on an issue on which am working right now..
Here is the scenario.


1. I have a windows.form.crystalreport viewer in my windows application in my main executable project file
2. I have a report viewer class in vb (in a separate project) which is used to gather all paremeters, conditions to Run a report
3. I have a report source as form or .rpt file in a separate project
4. I have referenced the projects mentioned in points 2 , 3  in my main executable project as mentioned in point 1.


Now, question is, how do I class my report viewer vb class in my
crystalreport viewer to get all the required logic and How do I have to call the
report source  in my Crystalreport viewer control?

thanks inadvance for any sort of suggestions.


thanks,
Sree.
