  http://www.vbdotnetheaven.com/UploadFile/dclark/StoredProceduresinVBdotNET04082005072716AM/StoredProceduresinVBdotNET.aspx

  Dim cmdData As New SqlCommand("usp_GetDatePeriodFromTo", cnPubs)cmdAuthors.CommandType = CommandType.StoredProcedure

I just setup
In my default page I have this?
Imports CustomerList.BOL
 Private _calendar As New BusinessCalendar()

 Protected Sub cmdProceed_Click(ByVal sender As Object, ByVal e As System.Web.UI.ImageClickEventArgs) Handles cmdProceed.Click
        _calendar.GetBusinessCalendarPeriod(txtPeriod.Text)
    End Sub

where txtPeriod = YYYYMM

  Namespace CustomerList.BOL

    Public Class BusinessCalendar

        Public Shared Function GetBusinessCalendarPeriod(ByVal DatePeriod As String) As DataSet
            Dim db As DBAccess = New DBAccess
            db.AddParameter("@YEARMONTH", DatePeriod)
            Return db.ExecuteDataSet("usp_GetDatePeriodFromTo")
        End Function

    End Class

End Namespace
