I have several web forms which use a GridView linked to a DataSource control which is defined at design time as follows:
<cc1:pgsqldatasource
id="dsStates"
runat="server"
connectionstring="<%$ ConnectionStrings:PgSqlConnection %>"
oldvaluesparameterformatstring="Original_{0}"
providername="<%$ ConnectionStrings:PgSqlConnection.ProviderName %>" >
</cc1:pgsqldatasource>
As you can see, the connectionstring parameter is defined to a specific connection string name and I need to be able to set such a parameter to a different value, for example, to a session variable content.
I'm trying to create a sql script that will connect to 1 server, backup 2 dbs, then connect to another server and restore the dbs. know i could create an application easily, use sqlcmd too but I wanted to do it on SQL Server Management Studio. I'm running version 10.0.2531.0
View 3 RepliesI am thinking of putting a drop down list to choose a couple of options. Depending on what is selected I want to then specify a specific connection string. I use the ConnectionString="<%$ ConnectionStrings:SomeConnectionString %>" format. How can I handle this in the .aspx page?

I am using CLR project in my website.I have used bulk insert in there.I am not able to use context connection in the procedure.Is there any way to get the connection string from web.configor from context connection.
View 5 RepliesI have an app that connects to only one db for all of the data that the app has access to. My connection string is in the Web.Config file. In each of my DAL classes I have the following code that gets the connection string from the Config file. This works with no issues but I thought there might be a better way of doing this that I don't know.
If I wanted to change the name of the connection string that any of the DAL classes would use then I would have to change the name of the connection string in each of the files. I thought about creating a new class that would hold this then I could just instantiate a new instance of the class to access this with each of the DAL classes that needs access to it. Then if I needed to change the name of the connection string then it would only be in one place. I suspect there is an even better way of doing this that i don't know about.

My question is: I have update stored procedure in my database (simple update stmt) I am finding difficulty in writing a ADO.Net(C#) connection string for update stored procedure. i have 4 columns and i first 3 columns have constant values. The 4th column values needs to be updated. At the same time i need to increment and then update the table.
View 2 RepliesI am using LINQ to SQL files in my class libray since every LINQ to SQL sources file is a seprate file and i have to set database connection string in each class library. Now, i have total 7 class libraires in my project how connection string be passed from web.onfg to LINQ file, so that i don't need to manually change the connection string. lke we did in asp.net 2.0 using connection string property in class file library.
How could we pass the same in LINQ's designer file.
Is it possible to assign the connection string in session variable and is it the good way to declare in session.
provide the sytax for accessing connection string from session variable
How to connect to different data providers(Say Oracle and SQL Server) using single connection string?
View 1 RepliesI only made 1 other dynamic page before, without users. I do remember I setup a read-only user to the database and that was the user used in the connection string, simple.
In managing multiple users, does asp.net's membership & roles automatically switch up the databases connection string upon login? Do you setup hypothetical "groups" of user access permissions in your database (mysql) then associate that user to that group in membership & roles?
I'm just looking for a general idea of what to expect before I start reading.
Background: I use SQL server 2005 developer edition and visual studio 2008. Visual studio 2008 is running on a local machine with Vista business edition. SQL server is running on a remote server using Windows server 2003. Both computers are within the same domain.
Problem: First, I used the server explorer to connect to the SQL server. Everything works as desired. Then I write code to do the same thing. I keep getting the following error message:
A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: SQL Network Interfaces, error: 25 - Connection string is not valid)
However, I used the exactly identical connection string as the one used in the server explorer. So connection string should not be the problem. In addition, I tried the test code in MSDN, which tells whether my domainusername can flow the network. It turns out the user name is fine. I also went to the SQL server management studio and found the login for my computer is NVCWeihao while my computer login name is NVCweihao. I am wondering if this uppercase letter really affects the connection.
I had been using the "regular" System.Data syntax to create connections on web forms, like:
dim conn As New SqlConnection(ConfigurationManager.ConnectionStrings("myconnStr").ConnectionString)
dim myCommand as SqlCommand
myCommand = new SqlCommand("my sql statement", conn)
myCommand.Connection.Open()
myCommand.ExecuteNonQuery()
myCommand.Connection.Close()
I say "regular" because most examples I've seen use this syntax, but more recently I've started using:
Using conn As New SqlConnection(ConfigurationManager.ConnectionStrings("myconnStr").ConnectionString)
dim myCommand as SqlCommand
myCommand = new SqlCommand("my sql statement", conn)
myCommand.Connection.Open()
myCommand.ExecuteNonQuery()
myCommand.Connection.Close()
End Using
...because recently I've seen some examples using this syntax.Even more recently, I've discovered that I'm getting some connection timeouts on a busy website I created a couple years ago. After googling the error, I found a few threads stating that the second example above will provide immediate automatic cleanup of connections, and in looking over the website, I'm using the first syntax exclusively.
My question is, am I creating the problem by not fully tearing down the connections in my code above (merely closing them, but not actually destroying them)? Do I need to do something like "set conn = nothing" like I used to do in VBScript?
And if so, will using the second syntax take care of this problem?
I have a db connection string 'ApplicationServices' defined in the connectionString section of web.config and 3 Entity Framework connection strings which have the provider connection string attribute with the same connection string as the one in 'ApplicationServices'. Is there a way to reference connectionString in 'ApplicationServices' for the provider connection string attribute of the EF connection string in the web.config, rather than providing the connection string all over again?

In my DAL i have more than 100 methods/Function, each and every method am opening the sqlconnection and closing the connection, this is taking too much of time to establish the connection at every time. So what i expect is one common class will create the SqlConnection that will check if the connection is Broken or Closed then create the connection again else return the connection, how to do this(Also i would like to apply ConnectionPooling).

View 1 RepliesI am preparing for an Access2007 db conversion at the beginning of the year and would like to know what the best process would be for connecting to the sqlserver2005 database. I have read about adding the connection string to the web.config file. I have also read about using ADO.NET and put the connection information into a class and not the web.config file.
I would like to hear from others as to what you have used, are using, or plan on using for a webapp (vs2010), and why so I can get an understanding.

My question is, when I want to connect to SQL using a "trusted connection" in the Connection String, what user will actually be passed into SQL?
I thought it would pass my logon details, but it is coming back with an NT AUTHORITYANONYMOUS LOGON error, which seems to point towards it not passing in my logon.
