How to pass parameters to crystal report from vb.net code

I have created crystal report (cross tab). Am not using any dataset instead i used the wizrd in crystal report to call procedure from my Database schema (Provider given is Microsoft OLEDB provider for oracle, after which i gave my DB credentials(i.e. schema, username, password) and selected the procedure and selected the columns i wanted to display in the report).

There are 5 parameters that i need to pass it from front end to generate the report. While viewing the crystal report preview, by giving parameters, the report works fine.

Now i want to pass these 5 parameters from front end(vb.net) to show the report in the CrystalReportViewer. Please suggest the code to write in aspx.vb file.
(PS:- I did go through other forums and found out some code, but all of them were giving some or the other error, so am posting one so that i can get the code specific to my requirement).

Thanks in advance..
