Problem with Parameters

I am writing a Data Processing Extension for Reporting Services and am
having a problem getting the values of parameters I pass in the query string
in ReportDesigner.
I have implemented the IDbCommandAnalysis GetParameters() method to parse
the query string in ReportDesigner. When I enter
"&CompanyId=1000&EmployeeId=2000" in the "Query string" field,
GetParameters() returns a local collection with my two parameters and their
values.
Upon command execution, the IDataParameterCollection IDbCommand.Parameters
property getter is called twice before calling ExecuteReader() and return my
member parameter collection. When ExecuteReader() is called, my member
parameter collection contains the two parameters of the correct name but
with values of null.
Because the parameters with correct names are added to the collection, it
seems that ReportDesigner saved the parameter collection I returned from
GetParameters() but what happened to the parameter values?
Since the values are null, ReportDesigner pops a window for the values to be
input. I don't want this to happen after the report is deployed but cannot
find a way to simulate the parameter name-value pairs being submitted on the
URL string.
What am I missing?
Thanks,

Thanks for your reply. I wanted to pass along some additional information
about the parameter problem I'm having.
I published my report and fount the parameters are passed to the report when
added to the URL. That's good, but it points out a big disparity between
parameter handling in ReportDesigner and in published reports.
I look forward to learning what you discover about the correct way to handle
parameters.
Thanks,
Tom

I am having the same problem. Did you ever figure this out for Tom?
I am trying to run a report by passing in the parameter through the url.
The report comes up but prompts for the parameter instead of taking it
through url. If I enter it at the prompt, the report runs fine. My url looks
like:
http://server-1/Reports/Pages/Report.aspx?ItemPath=%2fMarkListingbyStudent%2fMarkListingbyStudent&rs:Command=Render&calendarID=155
It's internal though.
Thank you for your help!
