Datareader for report?

[slwolf8]

Is it possible to attach a datareader to a crystal report? I successfully attached a report to a dataset but can't figure this one out. Here is the code I tried (vb.net):

Dim SqlConn As SqlConnection = New SqlConnection(ConfigurationSettings.AppSettings("SqlConn"))
Dim cmd1x1x61 As SqlCommand = SqlConn.CreateCommand
cmd1x1x61.CommandType = CommandType.StoredProcedure
cmd1x1x61.CommandText = "sp1x1x61"

Try
SqlConn.Open()
cmd1x1x61.ExecuteReader()
crv1x1x61.ReportSource = rpt1x1x61
rpt1x1x61.SetDataSource(cmd1x1x61)
crv1x1x61.DataBind()
Catch ex As Exception
Finally
cmd1x1x61.Connection.Close()
SqlConn.Close()
End Try

sorry, i have this as a public variable:

Public rpt1x1x61 As bakcr1x1x61 = New bakcr1x1x61

I should also say why I want to do it this way. I don't want to use a dataset because it is very very slow for the number of records we have.
