How to call ssrs report using report viewer?

[mcfarland]

Hello,
I created a new ssrs report and need to call this report from aspx page.
before that we have active reports when I click on btnprintpdf and btnprintexcel this will call active reports and generate the report;now currently no more active reports they are not working.so we created new ssrs report how can I call this from aspx page?
We have a table called reportexporttype and this will take care how to export this in pdf or excel based on id's.
This is the url http://devpps02/ReportServer/ReportExecution2005.asmx
This is the path
/FinWeb/SN/Reports/EligibilityInformation
