Hello All Experts 
I Have Connected to C# + Mysql useing dsnless connection . Every thing is fine and thank you . 
Now days I am trying to run a crystal report . 
I have installed cry report . 
I have made another report viewer form . 
I have created a crystal report . 
at the time of creating cry report i have set the query and with that query cry report runs without error . Even am calleing the the report viewer form with out error . 
BUT 
I want to make some changes in above method 
1 .   I want to pass the query to the cry report after taking inputs from user like  from date , To Date . 
2 after taking inputs from user . It should run the query useing user inputs. and pass them to the another form for viewing cry report output . 
Hope you can understand . Thanking you in Advance .
