Problem with Report Viewer in VS2005

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

I have the following code which compiles fine but the data set (ds) returns 0
count and the rptViewer1 is blank.
If I change the name of the rdlc file (rep.ReportPath = "Customer.rdlc" ;) to
something else which does not exist; this code still compiles and brings up
the empty report. What am I doing wrong?

namespace WindowsApplicat ion1
{
public partial class frmRptView : Form
{
public frmRptView()
{
InitializeCompo nent();
}

private void frmRptView_Load (object sender, EventArgs e)
{
FindAll();
}

public void FindAll()

dsMaintenanceDS .Name = "Customer";
dsMaintenanceDS .Value = ds.Tables["Customer"];
rep.DataSources .Clear();

rep.DataSources .Add(dsMaintena nceDS);
rep.Refresh();
}

OleDbConnection Myconnection = null;
DataSet ds = new DataSet();

Myconnection = new

}
