Password protect .mdb file

G

Guest

Hi

I'm using AccessDataSources to access my .mdb file, like so...

<asp:AccessDataSource ID="adsStory" runat="server"
DataFile="~/App_Data/MyDB.mdb"
SelectCommand="SELECT * FROM Table WHERE ColumID = ?">
<SelectParameters>
<asp:QueryStringParameter Type="Int32"
QueryStringField="id" />
</SelectParameters>
</asp:AccessDataSource>

I want to password protect the database in Access, so that if someone
downloads it they can't get to the data. How do I do that, and still able to
open the database from my AccessDataSource?

Obviously, I don't want the cleartext password in any of my .aspx pages.

Thanks,



Dan

You shouldn't. You would have to hardcode the database password, and that
would be like posting it on the internet. Oh, wait, it would *be* posting
it on the internet.

Hi Dan

The AccessDataSource can not connect to an Access database that is
password-protected. However you can retrieve data from a password-protected
Access database, use the SqlDataSource control.

Drag a SqlDataSource from toolbar on your design page.
Open the "Configure Data Source" dialog and click "New Connection" button.
Change the DataSource from "Microsoft SQL Server (SqlClient)" to "Microsoft
Access Database File (OLE DB)"
Then type your filename and password into textbox. (also check "Save my
password").

Additionally, for the security issue, you can save the connect string into
web.config file.

Please feel free to let me know if you have anything unclear. I will follow
up.
Hope this helps,
Sincerely,
Wen Yuan

If the connection string to the database is stored in your web.config file you can modify it there.
You can check the following for the connection string syntax and database password argument:

Hi guys

I'm having a bit of trouble getting these changes to work. Wonder if someone
can explain what I'm missing.

I exchanged the AccessDataSource objects for SQLDataSource objects, which
look like..

<asp:SqlDataSource ID="sdsTopStories" runat="server" ConnectionString="<%$
ConnectionStrings:sdsBeggars %>" ProviderName="<%$
ConnectionStrings:sdsBeggars.ProviderName %>"
SelectCommand="...">
</asp:SqlDataSource>

and changed the DataSourceID of my Repeater to "sdsTopStories".

VS added a connection strings element to web config which looks like...

<add name="sdsBeggars"
connectionString="Provider=Microsoft.Jet.OLEDB.4.0;Data
Source=|DataDirectory|\Beggars.mdb;Persist Security Info=True;Jet
OLEDB:Database Password="my password"" providerName="System.Data.OleDb" />

Which, when I test the connection, seems to work. But I now get the
following .net error when I debug my website... (im not passing any paraments
to my sql - it doesnt need any)
