using connectionstring in wpf project

hi ,

I have a wpf project that used data from some server on the net.
all my users suppose to have access to internet so it's not suppose to be a proble, in that matter.

I tried to create a setup project today after I checked that everything works as it suppose to, and after I installed it I discovered that there's might be a problem with connecting to the database, because suddenly any procedute that suppose to approach the DB doesn't work.

in my application I have a seperate projects for BLL and DAL to deal with openning/ closing and configure the connection details.

this is the app.config part, refering to the connectionsrting.

<?xml version="1.0" encoding="utf-8"?>
<configuration>
    <connectionstrings>
        <add name="oracle_vc" connectionstring="data source=xxx;persist Security info=true;user id=x;password=23;unicode=true" providername="system.data.oraclecleint" />    </connectionstrings>
 ...
</configuration>

Edited:
In other words-
I don't get any errors BUT, all I can say is that on a button click event, there's suppose to be a function checking if an item is exist in the database and if so, it goes to a new form. otherwise I get a msgbox saying "item doesnt exist".
In debug mode everything works fine (MEANING: if item exists > a new form opens).
When I create a setup project and run the application, I get for the same items I found earlier , the msgbox- "item doesnt exist", and that led me to the conclusion that something is wrong in the part that refers to approching the database.
Also since I'm using oracle connection string in my app.config file to connect to the database - like I used to do in winforns, I thought that maybe it's not working the same way in WPF and maybe that's what causing the problem.

Any help will be appreciated.


Thanks
