Hi,
I am adding text to a text file but I don't want to have any duplicates. I am searching a system for files and if the file occurs twice I only want it added once to the text file.
If any one can help it would be great.
Thanks

i'm really enjoying the simplicity in how to pull data in vb.net 2005
i've got a data source (pointing to an access db),
i throw a few controls in my form, i open that cute database designer
add my query which selects various fields from a table WHERE (ID=?)
and voila, i can pull data in my program.

but now i don't want to get data "where id = ?" only, but i want "where id = ? or id = ? or ..."
so i tried "WHERE (?)" but u arent allowed to pass sql code, only parameters. (obvious)

does anyone know the easiest, least painful way to do this ?

<br />
Dim Sql1 As String<br />
<br />
sSql1 = " Select * where id like '%'"<br />
<br />
'connection<br />
"osql -S " & [Server] & " -d " & [database] & " -U [User] -P [Password] " & "-Q """ & sSql1 & """" & " -n -o """ <br />
