Crystal report 8.5

Here’s my problem
I don’t know how to make a report of crystal report 8.5 obtain data in runtime(only with code or using a query).
I’m using a SQL server database and Visual Basic 6.0 and i’m tryng to pass a recorsource in runtime because i use a lot of filters, so i need that my reports will change dinamicaly.
And also my last reports of crystal 4.6 don’t get refresh in the previus or printing form.
