crystal report problem when converting project from .net 2003 to .net 2005

[ssfftt]

I developed an application using vb.net 2003, which contains crystal report, in the code, i gave the parameter values, so that when "report" button is clicked, the report automatically displays itself with given parameter values.however, i opened this application within vb.net 2005, and converted it into a .net 2005 project, after all this, when i run the applicaiton, and click on "report" button, it started asking values for all the parameters, why? plz help
here is the code: (blue-colored area is most likely causing the problem, i checked the outputs of sqlcommands, all fine, seems that somehow the sqlcommands output values are not passed on to the report's parameters)
