Generate report from URL - SQL Server Reporting Services 2008

Question

I have SQL Server Reporting Services 2008 and when I open the following URL:

"http://localhost/Reports/Pages/Report.aspx?someReport"

I'm getting report screen in which I fill my parameters and generate a report,

My question is how can I do this without any GUI? by batch file or C# script..

Thanks in advance.

EDIT:

Thanks to all answer above I succeed to generate a report and save it as an XML using the following link:

"http://Server/ReportServer/Pages/ReportViewer.aspx?someReport&dFrom=01/01/2012&dTo=08/08/2012&rs%3AFormat=XML"

Thanks for you all!!!

Answer 1

Your problem is you are passing parameters to http://server/reports... you need to pass parameters to http://server/reportserver...

I remember this issue I had when I first started using Reporting Services.

Here's the MSDN that may help you: http://msdn.microsoft.com/en-us/library/ms155391.aspx

For example, to specify two parameters, “ReportMonth” and “ReportYear”, defined in a 
report, use the following URL for a native mode report server:

http://myrshost/ReportServer?/AdventureWorks 2008R2/Employee_Sales_Summary_2008R2&ReportMonth=3&ReportYear=2008

The result is like so:

http://myRSServer/ReportServer/Pages/Report.aspx?%2fDefaultTenant%2fDialing+Reports%2fDialing+Agent+Performance&dFrom=01/01/2012&dTo=08/08/2012

If you want to export the report to excel / pdf / etc you can append it:

For excel: &rs:Format=Excel

For PDF: &rs:Format=PDF
