  Hello,
  
  1) Call the designer to create the report, then save the report to a file:
  

  Dim Cmd1 As SqlDataAdapter = New SqlDataAdapter("Select * from rest where (g2a =" & 2 & ")or (g2a=" & 0 & ") and (lname=N'" & txtlname.Text.Trim & "')", cnn)
  Cmd1.Fill(ds, "rest_tbl")
  ' create report instance
  Dim report As New Report
  ' register the dataset
  report.RegisterData(ds)
  ' design the report
  report.Design()
  ' free resources used by report
  report.Dispose()
  

  
  2) run the existing report:
  

  Dim Cmd1 As SqlDataAdapter = New SqlDataAdapter("Select * from rest where (g2a =" & 2 & ")or (g2a=" & 0 & ") and (lname=N'" & txtlname.Text.Trim & "')", cnn)
  Cmd1.Fill(ds, "rest_tbl")
  ' create report instance
  Dim report As New Report
  ' load the existing report
  report.Load("report.frx")
  ' register the dataset
  report.RegisterData(ds)
  ' run the report
  report.Show()
  ' free resources used by report
  report.Dispose()

  When you design a report, which datasource do you use? Is it the typed dataset, or something else?

  Ok, use the following code:
  

  Dim Cmd1 As SqlDataAdapter = New SqlDataAdapter("Select * from rest where (g2a =" & 2 & ")or (g2a=" & 0 & ") and (lname=N'" & txtlname.Text.Trim & "')", cnn)
  Cmd1.Fill(ds, "rest_tbl")
  ' "existing_table_name" is the name of the table in your report
  report.RegisterData(ds.Tables("rest_tbl"), "existing_table_name")
  report.Show()
