Web Forms :: How To Get The Data Source Value In The Connection String For That User
Jul 10, 2010
when user logins to my website i want to acess the users local database, all user having the same database name, same tables every thing but they are not connected in network .so i want to know how to get the data source value in the connection string for that user, so that i can acess his local database.
i have a code which has the connection string as driver. dim s as string = "Driver={SQL Server}; Server=xxxSQLEXPRESS; Database=dbRegister; Trusted_Connection=yes"
I am writing a web app for work. The users who are using this app will not be using the same connection string- for example, we have about 40 customers whose data resides in their respective database. The goal of this app is to be able to query the database for a given customer without having to go in and modify the web.config connection string (obviously, because that will change the connection string globally across users- I want the users to be able to have their own local connection string to be used by the app). is this possible?
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?
I am doing a web project in asp.net. Now I am trying to keep each connection string for each user. And the user can decide which server he prefer. How to change this dynamically and where can I store this?. I happen heard about machine.config .Unfortunately i am not familiar with this. Can you just tell what it is and it's use.
Is it possible to insert a connection string into a web.config file if it isnt there?Would this work?The connection string is for a APS.NET user login and create account database.
just for my testing purpose i know i can define both the connection's outside in a single web config file by different name's and access them in my front end according to it but what if i want to have seprate for both connection's web.config situation is like this see image so i want to access my connections from second web config file how i can do that.
I can successfully run a sample report on the local computer. DataSource and Report are valid it renders perfect.
But when i move my DataSource and Report to Remote server which is hosted by a company, then i always receive following error!. It is really disgusting.
An error occurred during client rendering. An error has occurred during report processing. Cannot create a connection to data source 'DataSource1'.
For more information about this error navigate to the report server on the local server machine, or enable remote errors

I'm just stumped on what to do with this code, I'm just trying to implement a 'no duplicates' catch on my insert customer form, but it just slips through my if statement to the else everytime. This is the source. Also I tried a .Equals with the same results :(
Protected Sub srcAllClients_Inserting(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.SqlDataSourceCommandEventArgs) Handles srcAllClients.Inserting 'Establish Variables Dim emailAddress As String Dim srcUsers As SqlDataSource = New SqlDataSource() srcUsers.ConnectionString = ConfigurationManager.ConnectionStrings("ISSD21ConnectionString").ConnectionString Dim view As DataView view = DirectCast(srcUsers.Select(DataSourceSelectArguments.Empty), DataView) srcUsers.SelectCommand = "SELECT EmailAddress FROM ISSDClients" srcUsers.DataSourceMode = SqlDataSourceMode.DataReader Dim reader As IDataReader reader = DirectCast(srcUsers.Select(DataSourceSelectArguments.Empty), IDataReader) emailAddress = FormView1.FindControl("txtEmail").ToString While reader.Read() If reader("EmailAddress") = (emailAddress) Then lblError.Text = "Your Email is NOT Unique!" 'this is where we cancel the update and return an error Else lblError.Text = "Your Email is Unique!" 'nothing needs to happen, maybe just tell them that it went through End If End While reader.Close() End Sub
I 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.
I have an ASP.Net website running on IIS7. The Application Pool is set to ASPv4 Classic.
Authentication Mode is set to ASP.Net Authentication & Windows Authentication
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.
and this database lmslive is in a system next to mine connected via proxy.... And i executed this query on that system,
GRANT ALL PRIVILEGES ON lmslive.* TO 'lmslive'@'10.1.1.15' IDENTIFIED BY 'lmslive' WITH GRANT OPTION; I get the error, Access denied for user 'root'@'XAVY-PANDIYA' (using password: YES).. what am i missing?
I have put my web project (which uses reporting services) into the web server for testing. All works fine on th elocal machine but on the server I get this error when trying to access the reports: The permissions granted to user 'NT AUTHORITYNETWORK SERVICE' are insufficient for performing this operation. (rsAccessDenied) I have now done this: go to the property tab and create a new group with name BUILTINUsers And in the role assignment tick browser role Now the error is :
An error has occurred during report processing. (rsProcessingAborted) Cannot create a connection to data source 'dsDB'. (rsErrorOpeningConnection) For more information about this error navigate to the report server on the local server machine, or enable remote errors
But it shows me an errormessage when I run this query:
string query = "Select * from [IO_Definition$]";
IO_Definition is the name of the spreadsheet in my excel file. I also added the excel file to the App_Data folder of the website.
The error is:
The Microsoft Jet database engine could not find the object 'IO_Definition$'. Make sure the object exists and that you spell its name and the path name correctly.
The thing is, when I write the absolute path of the excel file in the connectionString it does work. Is there anyway I can make it work without writing the absolute path?
public class DataClass{ public DataClass() { } /// <summary> /// return rows depend on position /// if you need 10th to 20th you need to pass start=10 and end=20 /// </summary> /// <param name="start">database start position of one row</param> /// <param name="next">database end position of one row</param> /// <returns></returns> public string GetAjaxContent(int start, int end) {

When I'm trying to develop the unlimited scrolling in datalist i have an error like connection string not initialized I checked and rechecked.
on VWD 2005 this code works fine, but on 2008 it says I haven't created an instance of the object. I want to convert the object connString (a connection string) into a string.
'This acceses the virtual directory web.config file for connection strings 'We have to convert the object to a connection string Dim rootWebConfig As System.Configuration.Configuration rootWebConfig = System.Web.Configuration.WebConfigurationManager.OpenWebConfiguration("/VirtualDirec") Dim connString As System.Configuration.ConnectionStringSettings connString = rootWebConfig.ConnectionStrings.ConnectionStrings("ConnectString1") Dim strConnString As String = connString.ToString().......

I am making use of 3-Tier architecture while making my project.

I'm using Visual Studio 2008, and my database is SQL Server 2000.
I want to add a connection to the Server Explorer in VS. The Data source is Microsoft SQL Server (SqlClient). After entering in all my information and I click Test Connection, it is successful.
But when I click OK, I get the error:
Unable to add data connection. ExecuteScalar requires an open and available connection. The connection's current state is closed.
I ahve a solution with a few dll projects, a winforms testbed and a WCF webservice project. In the data project, I have a base class that does the following:
public class BaseDAO { private const string CONNECTION_NAME = "OracleConnectionString"; protected static string GetConnectionString() { ConnectionStringSettingsCollection settings = ConfigurationManager.ConnectionStrings; string conStr = ""; if (settings != null) { foreach(ConnectionStringSettings setting in settings) { if (setting.Name == CONNECTION_NAME) { conStr = setting.ConnectionString; } } return conStr; } else { throw new NotImplementedException("The connction string can't be found"); } }
You might ask, why do I need to loop and check the name against a constant? Well, I have defined the connection string in the service project's web.config, but this above code always find two connection strings, one is a sqlexpress which I guess is a default database of some sort. So, to separate that one against the one I really use, I have to loop through all entries and pick out the one I plan to use. How do I prevent this? Is there a better way to fetch the connection string from the data project?
