problems with connection to Oracle

[Artur]

Ok, I installed an Oracle 8.1.7 database. Under MSVisual Studio.NET I
to put a configured oracleConnection component onto a form.
I previously created this connection based on Microsoft OLE DB
Provider for Oracle and put a servername, user name and verified "Test
connection" - it was ok.
I also check weather tables of my Oracle databese are available via
Server Explorrer - everything was fine. Then I ran the application and
, after proper compilation I got this message:

"An unhandled exception of type 'System.Security.SecurityException'
occurred in WindowsApplication8.exe

Additional information: Request failed.
"

Does anybody have any suggestions ??

You may want to identify the line of code on which the error occurs.
