Hi all,

I 'm developing VB .NET application that access MSDE or SQL server. When I
need to access DB, I directly send connection string to DB then another user
can filter my account and password.
Our program use SQL Mix Mode authentication that can use both Windows
authentication and SLQ authentication log on.
I would like to prevent my account and password when I use SQL
authentication log on.

How possible is it?

Cheer,
KPH
