please help with ASP.NET access MSDE

[Ammar]

Hi ...
I have been reading throuhg the internet to solve a problem that happens to
me when i try to access a databse in SQL mode...
when i access the database through (visual web developer 2005) ie testing
it, then everything runs perfect! but then i simply connected the database
to the page by draging the table to the ASP.NET page and the web developer
creates the necessary code... it seems that the page access the Database
using windows authintication...
but when i run the same page through the IIS (http://locahost/default.aspx)
i get the message at the end of this page


I am guessing that the page tries to access the database through SQL
authintication...

I have many questions please:
1- when i install MSDE i can specify SA password, but what is the user
name???
2- is it that user name and the sa password that is used when accessing
database through SQL:
conAB = New SqlConnection( "Server=localhost;uid=?;pwd=?;database=dbname" )
3- what is this "mixed SQL mode " that i have to enable to allow connecting
to DB by sql and not only windows authintication???
I would appreciate it if i could get answers to those question.
and i thank you all for your time
Ammar
