SQL Server :: Define And Read ConnectionString From Web.Config?
Dec 17, 2010
I am new to asp.net and wondering if anybody can help me defining SQL Server 2005 ConnectionString in web.config file and call/read anywhere in application on any button.Kindly provide me code example.
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?
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 wonder how often the Web.config file is read by the server?And if the fact of the Web.config file is too large, influences the application performance?
how can i encrpt database password and store to Visual Studio's connectionString areaalso, i would like to know how can i set all config in config file and how the program can read.
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:
I know this might be a very basic question, but maybe thats why im having problems finding the answer. Right now I'm creating database connections in my source files by doing something like this:
SqlConnection con = new SqlConnection("Data Source=...Password=...); SqlCommand cmd = new SqlCommand(String.Format("SELECT * FROM Table;"), con); con.Open(); SqlDataReader reader = cmd.ExecuteReader();
But this means that if I choose to change databases it will be a major pain in the ass. Do you guys know how to use the connection string from a web.config file instead?
I'm using MySql in my asp.net project. But I don't want to type every "using MySql.Data.MySqlClient;" statement in every aspx.cs/aspx.vb file. How can I define this lines in web.config file?
I've defined some namespaces like below but this only works for aspx pages:
I want to setup the connectionstring of the SqlDatasource of a dropdown list at runtime, eg. Page Load event. I have install MySQl ODBC driver, System DSN name as "MySQL_Employee" If I have an entry in Web.config:
<connectionStrings> <add name="mysqlConnection" connectionString="DSN=MySQL_Employee;UID=john;description=connection to employee database;server=empServer;database=employee;port=3306;" providerName="System.Data.Odbc"/> </connectionStrings>
I encrypted my connectionstring and store at web.config file. Then I bind Gridview with sqldatasource control, cannot bind because of sqldatasource don't know the(encrypted) connectionstring.
The httpRuntime element configures ASP.NET HTTP run-time settings that determine how a request for an ASP.NET application is processed.
Is it a good idea to customize this element in the config file.
The user has indicated that the application seems to be kicking her out, even though she is sure that she is submitting a form faster than every 30 minutes.
My Config file has these vales set, am I missing anything?
We are experiencing some strange behaviour on one of our ASP.NET web servers (Windows 2003 64-bit). After some activity, two third-party controls are unable to run correctly. One is log4net (it does not write error messages out) and the other is a menu control (it displays eval message instead of picking up its license). The one common thread is that both controls pick up their config from external config files (linked to from web.config).
Just wondering if anyone has any thoughts on this or experienced this in any way. Is it related to file/folder rights? The server has been running fine for a while and just started exhibiting this behaviour. Perhaps it occurs around the time the worker processes are recycled.
I have many Connection strings in my web.config file. I also have a "dataConfiguration" setting in the same file which specifies what database my app connects to.
