I've got a program that collects info from an Access. I'm trying to use the
following select command to select all the information from the "Families"
table and store it in a dataset, plus join the Surname and FirstName fields
to create a new field, FamilyName:
selFamilies.Com mandText = "SELECT Families.*, Families.Surnam e + ', ' +
Families.FirstN ame AS FamilyName FROM Families ORDER BY Surname, FirstName"
This has been working perfectly a number of times until recently, and now
when I try to run the program, it stops on this line:
adpFamilies.Fil l(datSPARK, "Families")
and gives me this error message:
"An unhandled exception of type 'System.Invalid OperationExcept ion' occurred
in system.data.dll
Additional information: Invalid attempt to NextResult when reader is
closed."
I'm new to the whole database thing, and this message is Greek to me. If I
use this simple select command instead:
selFamilies.Com mandText = "SELECT * FROM Families ORDER BY Surname,
FirstName"
the program doesn't give me the error.
I would really appreciate any help anyone can give me.
Thanks

Try this
Try
selFamilies.Com mandText ="SELECT Families.Surnam e, Families.Surnam e FROM
People ORDER BY Families.Surnam e, Families.Surnam e"
Catch ex as Exception
MessageBox.Show (ex.ToString())
End try
Hopefully this amended Commandtext will do the trick, if not at least you
will get an error message with a bit more detail.

Sorry, I don't understand what your select statement was supposed to
accomplish. If I use that statement, no errors are encountered--the adapter
is not having any trouble accessing the FirstName and Surname columns. But
I tried the Catch and got this "explanatio n":
