How to pass parameter to crystal report viewer with VB.NET?

I want to pass parameter to a crystal report viewer. I added .rpt file to the report viewer, but I can't get the parameter field to bound the variable.

How can I pass parameter to that viewer?

I added crystal report file to the viewer, but in the report file contains 4 parameters. I tried to use CrystalReportViewer1 to get parameter function, but i ca开发者_高级运维n't find parameter function.
