WebMatrix :: Use Database.Open For ConnectionString From Web.config?
Aug 12, 2010As mentioned in this tutorial (http://www.asp.net/webmatrix/tutorials/5-working-with-data), I tried using my own connectionstring from web.config.
I got this error: "Format of the initialization string does not conform to specification starting at index 0."
The tutorial suggests to use: Database.OpenConnectionString("SmallBakeryConnectionString") method
Instead you should use Database.Open("ConnectionStringName").
Ref: http://cytanium.com/forums/yaf_postsm18_Connection-string-problem.aspx
The API Document is missing Database.Open method and also Database.OpenConnectionString info needs to be modified.

ADO.NET :: How To Use Connectionstring From Web.config
Jan 2, 2011I have a connectionstring in my web.config <add name="HeimkinoVerbindungszeichenfolge1" connectionString="Data Source=SERVER;Initial Catalog=Heimkino;Persist Security Info=True;User ID=sa;Password=*******;"providerName="System.Data.SqlClient" />
This itself is working when using eg the SQLDataSource for a Gridview or similar.
Now I need to access this DB with different scripts and work with that database.
Eg I need to run this comand in a page_load against the DB
[Code]....
to remove old events from the database
For other pages I need something like
[Code]....
for some userauthentication things this should just create a recordset I can work with then.
Is there a way to realize this using the connectionstring in the web.config (and if so, How???)
If this will not work, how can I run such queries?

Connectionstring Encryption In MVC2 4.0 App?
Nov 16, 2010I have an MVC2 .NET 4.0 app, hosted on TFS 2008 (soon to be TFS 2010) that uses connection strings in web.config to connect to a database on another server. I need to encrypt these connection strings.
As I understand it, I can use aspnet_regiis.exe to encrypt the connectionstring portion of the web.config file, but I have to do it on the deployment machine because the encryption uses the machine name to generate the encryption key.
Now, it seems to me that this represents a problem - every time I deploy my code to the dev server won't it overwrite the web.config file, and need to be re-encrypted? This sort of manual process seems kludgy.
Is my understanding about needing to re-encrypt after deployment correct? If so, is there some way to automate this process? I don't want to forget this or get a new team member who doesn't know the process and have the connectionstring exposed to the world.

Security :: Encryption Of ConnectionString?
Sep 18, 2010My website has to connect to a hosted SQL Server database. The connectiostring, incluing username and password, is stored in the web config file.I have two questions.The first is that everything I read says this must be encrypted so that it cannot be read and used by others. Well, how would that happen. My understanding of ASP.net is that all the work is carried out on the hosted server and the rendered page is then delivered to the user. How would a user be able to view my connectionstring.Secondly, I have used some msdn vb.net code to encrypt the connection string in the web config file. Following on from the first question, how can I confirm that the encryption is intact on the published web.config file.
