DataSource Controls :: Set Up Connectionstring At Runtime From Web.config - MySQL?
Jul 7, 2010
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>

environment: W7 Ultimate 64, VS2008, Mysql 5.1.45, Connector .Net 6.2.2
.aspx environment: a DropDownList (DDL) triggers a DetailsView (DV). All functions (select, edit, new ...etc) work fine.
Now, in the same .aspx page I use Event "SQLDSDVKlient_Inserted" to get the Last inserted record ID using "ExecuteScalar" method! This to fill the DV with the just created record using "New" (see code below).
on "cnn.Open()" I get below error msg; Event code 3005!
Some additional info:
a) keep in mind this all happens in the same .aspx page
b) In the MySQL wizard (5.1.45) I clicked the "allow remote connections".
c) the ConnectionString is copied out of web.config (remind you: all 'normal' DV functions work fine.I.e. I certainly can connect to my MySQL DB.)
d) When using, in ConnectionString, the parameters "Allow User Variables=True;old guids = true" I get, on statement "cnn = New Data.SqlClient.SqlConnection(connString)" a msg: Keyword not supported"; so I removed it.
e) without above connectionstring parm I get on statement "cnn.Open()" below error msg: where I need help!
Questions:
1) why does the system suddenly bring the remote connection into play?; I'm always on the same machine, same .aspx page!
2) what is the role of the "mysql connector.net" (6.2.2) in this scenario ?

SqlConnection conn = new SqlConnection("Persist Security Info=True;Data Source="+txtdatasource.Text+";database="+txtDBName.Text+"; User ID="+txtDBUsername.Text+";password="+txtDBPass.Text);
conn.Open();
SqlCommand cmd =new SqlCommand("SELECT [ItemCode],[ClientDescription] FROM ["+txtDBName.Text+"].[dbo].[Bookings]");
cmd.ExecuteNonQuery();
This gets the folowing error ExecuteNonQuery: Connection property has not been initialized. i know it connects to the database

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 have a class library that contains a valid connectionString inside the app.config. Inside that class library I want to use it with
ConfigurationManager.ConnectionStrings["NAME"].ConnectionString
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.
ConfigurationManager.ConnectionStrings["NAME"].ConnectionString

I have the following in my web.config
<connectionStrings>
<add name="ActiveDirectoryConnection" connectionString="LDAP://ActiveDirectoryDomain1.com" providerName="System.Web.Security.ActiveDirectoryMembershipProvider"/>
</connectionStrings>
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:
<activeDirectorySecurityContextSettings connectionStringName="ActiveDirectoryConnection" defaultADUserName="ReportUser" defaultADPassword="password"/>

The data is display when i select the SELECT query from wizard while add dataset, but i want to do it dynamically coz webserver is located somewher else. Configuration is MSSQL server 2000, W2K3, VS 2005 Professional.
I did a Crystalreport projects with vb6 with ado but i really dont know how to exactly dynamically generate conditional report in Reportviewer.

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?

As 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.

I checked my Username , Password and its Permissions for thousands time, and everything seems to be alright. I developed the Website by ASP.Net / C# (VS2008) and SQLServer2008 and I guess the problem is with ConnectionString, below you can find my ConnectionString:
Server=(local)SQLEXPRESS;User ID=myusername;password=mypass;Database=mydb;Persist Security Info=True

I'm trying to set up a simple content management system for two different sites, which are both stored on the same server (my own, not hosting, if it matters:)).
Both sites are basically the same, built upon a similar (but seperate) xsd (Typed DataSet) file, and read data from different databases using the tableadapters in the xsds.
Obviously, i have the same xsd setup in my management system application that need to hook up to the relevant database (after user authentication) and use the tableadapters to access the data and allow the forms in the management system to modify the data.
When i had a single site, the connection string was stored in the web.config file and after logging in to the management system, all forms could access the database.
Now i have two site and i need to setup the connection string in the xsd dynamically after user validation based on the relevant site to edit.
My question is, how do i set the xsd's connection string dynamically (after user logs in, the function returns the specific connectionstring and stores it in a Session variable)
