i have a class library and i want to use it in difrent web form application.
i created a linq data class and i drag and drop the table of my local database in it.
now i want to use this class library in my web form application with a database in server with difrent database name but with same tables and also the connectionString Name is the same.
in my class library i call myDataContax("MyConnectionStringName")
my question is when i use a connectionstring with the same connectionString Name as my Class library ConentionString Name but with difrent database name it will work or not?
I need to add a dropdown box to my login page that allows the user to change the connectionString to a different string, e.g. "LDAP://ActiveDirectoryDomain2.com"
In C# code behind how do change the connectionString value?
More info:
The problem I am having is that there are 4 other web.config settings call that one connectionString. For example:
My application is used by several customers, who needs to maintain their own database. Currently I'm keeping all the connectionstrings and according to the user, change it. (In a case of CRUD operation). Is this errenous way? I don't know much about MultiTenant applications. Is that the best solution for my problem?
I have a solution which uses Linq to SQL Data Classes to acced the db. I have a project for my domain objects in my solution, which is a class library and has the dbml file. When I set up the dmbl using the wizard, Visual Studio created anapp.config file on that project with the connection string. It also creatting asettings file with the same info. I've noticed that if I change the connection string in the settings file, the app.config gets updated, which is the expected behaviour.
However, I'm having a problem when I deploy my web site to the production server. I already set the app.config file's Build Action to "Content", and also set Copy to ouput directory to "Always". Nevertheless, when I install the web site and change the connection string in the app.config file, it still takes the old connection string, so obviously I get an error. I've found that it only works if I change it with in Visual Studio and then compile, but of course that's not an optimal solution, because any change in the production db server would mean I have to change my project's assembly, thus generating a new version.
What do I have to configure so that the assembly takes the connection string form my app.config file directly after I deploy?
I am working on a project in which I have made changes to LINQ to SQL code in data access layer project.Initially the code was using Single() extension method, I have changed it to SingleOrDefault() was earlier method was throwing exception if no records found in db.
After making changes I ran the project but during debugging VS 2008 was showing that file is changed and do you want to reload the file box. When selected the file, the debugger was still executing the commented code (Single() method).I tried cleaning the entire solution and rebuilding it but it did not help. All the projects (Presentation, BL, DAL) are under single solution.
I 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?
I want to know how to pass connection string to my .dll file. I have created one Class Library(dll) now i am using the dll of that in my application. My application is going to deploy on client side so he will going to change the connection string. Now iwant to know how will i directly access the connection string from web.config to my dll. With that i also want to know how will i pass parameters to my dll. I have already tried but it is giving me an error:the remote server returned an error 500 internal server error. Class Library Code:
[Code]....
Web Form Code: where i am using the object of my dll
can anyone tell me on how this encryption done? i know the standard way of encrypting using aspnetregiis.exe which replaces the entire connnectionString section of the web.config.
I 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.
in one of the application i have been reffering connection string is stored in appsettings! till now i have been storeing the connection in <connectionstring/> element. But, what is the correct way?
So my quetion is, What is the differences between <connectionstring> and <appsettings> in web.config, are there any specific reason why i should or should not be storing connection string in appsettings? Are there any rules / guidlines provided to follow? Or is this completely the choice of the developer?
In 3 tier architecture where to keep connection string? I have presentation layer ( webapplication) and BAL Layer ( class lib) and DAL (class lib).intially i kept in web.config which is in presentation layer....is it correct?should i keep a app.config file in DAL layer and keep my connection string in that?Where to keep connection string ?
I just deployed my database to my remote server. I am trying to create a connectionstring to the remote server and it won't work. I am using godaddy. I kept having this message: could not establish a connection to the database. Here is the connectionstring for the local server:
My 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.
My ASP.net 4.0 framework application references that DDL and retrieves data from it. I want create a Entity Framework 4 DataContext within my DDL with the ConnectionString from the App.config. (I do not want to pass the connectionString from my ASP.net application in every single method. (I'm using ObjectDataSources))
However, this line inside my DLL throws a NullReferenceException.
i have some websites and one part of all websites is the same and it work with dataset i got an ide to creat a code projrct to handel that part and i use it in all websites the problem is the websites not use the same connectionstring but the connectionstring name can be same. i need to set this code project to read the connectiostring from the website web.config file.
I am developing a web application in Visualt Studio 2008. I have a data access layer that is automatically generated using Visual Studio. After publising my site to IIS and tested it for several hours, two exceptions occured:
[Code]....
The connection string is stored in the data access layer in Properties.Settings and has not changed.Does anyone have a clue why these exceptions occur and how i can avoid them?
n my ASP.NET application, I have a sqlclient connectionstring in my web.config file, What is the recommended timeout setting for production environment? Default is 15 seconds.My web farm and database cluster are on the same switch, so there should not be much latency.
