Why do i get "Invalid attempt to FieldCount when reader is closed"
Is the problem the way the datareader reads data as
opposed to a dataset?
When trying to compile this code:-
Dim reader As IDataReader = GetReader()
Dim chart As New LineChart()

If I run the stored proc in the Query Analyzer this works and I get the
expected result set back. However when I run it in my application I get
a results set of one row but when I try to access the values I get
"Invalid attempt to read when no data is present".
private void GetLotIDPriorityFromLot(string aLotDesc, out int aLotID,
out DateTime aPriorityDate)
{
SqlConnection Conn;

I'm a network technician in training and I need your help.
I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
