ReportViewer with multiple reports in winform

[=?Utf-8?B?TUZD?=]

Hello,

I have a windows application over data form that has a reportviewer control
on it. I have several reports defined, each works as expected when they are
embedded into the report.

On the form I have 3 buttons and two DateTimePicker controls. I want to use
the bottons to load the unique reports into the reportviewer. I want to use
the DateTimePicker controls as parameter inputs for one of the existing
reports.

I've spent days looking for a simple example or walkthrough but have found
either broken links or examples in c# (I'm still a VB newb, c# just confuses
me at this point) My Data source is an Access table, I've imported the
needed data as a dataset and used the tableAdapter query builder to some
limited success but I'm unsure of the relationship between the parameter
source (the DateTimePickers) and the datasource. I've read up on SQL Server
reporting services but I'm afraid that only added to my confusion. (I've also
perused "gotreportviewer.com")

I'm hoping someone will walk me through this two part question.

Thanks.
