I have a stored procedure in Oracle. It accepts two varchar2 parameters and returns a boolean value. I managed to send the parameters using OracleCommand object but I don't know how to retrieve the boolean value.
The ASP.NET code I have is the following:

Dim oraCmdLogin As New OracleClient.OracleCommand("compareLogin", oraConn)
oraCmdLogin.CommandType = CommandType.StoredProcedure

Dim login As New OracleClient.OracleParameter
login.OracleType = OracleClient.OracleType.Number
login.ParameterName = "login"
login.Value = 23
oraCmdLogin.Parameters.Add(login)

Dim pass As New OracleClient.OracleParameter
pass.OracleType = OracleClient.OracleType.Number
pass.ParameterName = "password"
pass.Value = 23
oraCmdLogin.Parameters.Add(pass)

oraConn.Open()

Try
oraCmdLogin.ExecuteNonQuery()

Catch ex As Exception
Response.Write(ex.Message)
End Try
oraConn.Close()
