View 3 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.

I try to connect my database for so long so i wrote two type of codes. Let's discuse first on.
I have database called PhoneDirectory.
It have only one table named Residents.
I have button wiht ID="Button1".
I want when i click this button to see all of my residents.
I want to see the result in DetailsView and to be able to edin, delete and add new resident.
First try with SqlDataSource so i wrote this:
<asp:SqlDataSource ID="Resident Details" runat="server" ProviderName="System.Data.SqlClient" ConnectionStrings="<%$ ConnectionStrings:ThisIsTheConnection%>"

View 1 RepliesIn 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 7 RepliesFirst off, I am just getting started with ASP.NET so I expect this is something that I am doing.
i am trying to make a connection to a MS SQL database on my local machine.
I have the following in web.config

I wrote in subject "Is there any way to UPDATE multiple rows WHERE UserID = @UserID_ArrayList" For example I have an Arraylist like this:
Dim UserID_ArrayList As New ArrayList
UserID_ArrayList.add("100")
UserID_ArrayList.add("150"
UserID_ArrayList.add("200")
Now I have to UPDATE some columns inside those 3 records WHERE UserID = @UserID_ArrayList I'm sure it can be done somehow?
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.

Everything seems really simple and cannot figure out why when I try to login to test the application , the error I get is: Must declare the scalar variable "@UserId".
I have a confusing question, I have a user table and it stores all the usual data for a user that you would expect but im trying to figure out how a user could add another user?
Sounds strange but each user in the User table has his own UI which is UserID how could I add another table where UserID can have a relationship with another UserID?
i.e how would I right the syntax for the above question if I wanted to display all the UserIDs friends on a page. How would I add a friend.

When I attempt to store the current time of 'DateTime.Now' in a column defined as time in a table within an SQL database, I get an error message that says: Cannot implicitly convert type 'System.DateTime' to 'System.Timespan'.
I have no trouble storing the current date of 'DateTime.Today' in a column defined as date, but this column will not also store time along with the date. The date column has properties that indicate it has a data and system type of date with a Length of 3 and a Numeric Precision of 10. The time column has properties that indicate it has a data and system type of time with a Length of 5, a Numeric Precision of 16 and a scale of 7. Did I define the time column incorrectly for storing the time of day?

I want to retreive some data from an SqlDataSource using it's Selected event I've tried
DataView dv = (DataView)SqlDataSource1.Select(DataSourceSelectArguments.Empty)
but here it's going into in infinite loop and then it gives me an StackOverflowException error in ASP.Net Development Server (my dev machine) and if I publish to IIS it requires me an user name and password to connect to server and gives an InternetExplorer error "Sys.WebForms.PageRequestManagerServerErrorException. An unknown error ... status code returned was 400. The SqlDataSource is in an UpdatePanel. Maybe this is why I get this.
