Hi I am loading my report and using this line of codes

Code:
Dim reportData As New ReportDataSource

    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        Me.ReportViewer1.LocalReport.ReportPath = Application.StartupPath & "\\Report1.rdlc"
        Me.ReportViewer1.LocalReport.DataSources.Clear()
        Dim ds As New WindowsApplication1.DataSet1
        Dim da As New WindowsApplication1.DataSet1TableAdapters.tbl_sentTableAdapter
        da.Fill(ds.tbl_sent)
        reportData = New ReportDataSource("DataSet1", ds.Tables(0))
        Me.ReportViewer1.LocalReport.DataSources.Add(reportData)
        Me.ReportViewer1.RefreshReport()

    End Sub
I'm thinking how can I change the command if I want to filter the output on my report.
on my table I have 'date' column. I want to insert a filter by date range sql command on my current code.
