Ok I'm pretty new to VB.net and I need some help. Somehow I've been able to
get this far, but I'm stumped. I'm managed to connect to both my production
database (Sqlbase) and a distributed db (Pervasive) thru ODBC. What I'm
trying to do is compare tickets on both: tickets are entered into Pervasive
and then transferred thru to Sqlbase. Some tickets miss the transfer because
of setup reasons etc. I need to find those tickets that miss the transfer.
what I need done is:

{fetch tickets from pervasive for a particular day in ticketno order}
while not done
{fetch ticket nbr from sqlbase where ticket_nbr=ticketno and
sale_date=date above}

Here's the problem(s):
1. I'm getting a data not numeric when it DOESN'T find a ticket on sqlbase
(ie the result is Null not integer)
2. I get a DataReader associated with this command needs to be closed.

sSelect = "select ticketno from tkhist1 WHERE TicketDate=? order by ticketno"
cmdA.CommandText = "select ticketno from tkhist1 WHERE
TicketDate=? order by ticketno"
cmdA.Parameters.Add("ticdate",
Data.Odbc.OdbcType.Date).Value = TicDate.Value
Dim bReader As System.Data.Odbc.OdbcDataReader =
cmdA.ExecuteReader()
'MsgBox(cmdA.CommandText)
cmdQ.CommandText = "select ticket_nbr from sale where
co_nbr=80 and locn_id=1 and sale_date=? and ticket_nbr=?"
Dim cReader As System.Data.Odbc.OdbcDataReader = Nothing
While bReader.Read()
aTno = bReader.GetInt32(0)
cReader = cmdQ.ExecuteReader()
'sale_date=?
cmdQ.Parameters.Add("ticdate",
Data.Odbc.OdbcType.Date).Value = TicDate.Value
cmdQ.Parameters.Add("ticno",
Data.Odbc.OdbcType.Int).Value = aTno
Try
If Not cReader.IsDBNull(0) Then
'aQno = cReader.GetValue(0)
'If aQno = Nothing Then
tbA.Text = tbA.Text & " " & aTno.ToString
End If
Catch ex As Exception
MsgBox("Error if finding Quest ticket: " +
ex.ToString)
End Try
End While
bReader.Close()
End If
