I'm not sure what the (Datatable) bit is for in that statement:
Dim myDataSource As ReportDataSource = new ReportDataSource("Dataset1",(DataTable)TableKu)
does it work if you use this instead?
Dim myDataSource As ReportDataSource = new ReportDataSource("Dataset1",TableKu)
If that doesn't work,
here[

here[
