What different are there between connectionString (Part 1) and connectionString (Part 2) in web.config The CCWW is my PC's name, normally I can connect to the database ASPNETDB.MDF correctly either Part 1 or Part 2 in a web page,After I open Database Explorer panel and browse ASPNETDB.MDF, I can't connect to database using Part 2 when I open a webpage in Microsoft Visual Web Developer 2005 Express Edition,but I can correctly open a webpage using Part 1 after I open Database Explorer panel. What different are there between connectionString (Part 1) and connectionString (Part 2) in web.config? I guess while I use Part 1 to connect, maybe it will be cancel exclusive method of the database ASPNETDB.MDF first, but when I connect to database using Part 2, maybe two programms both Part 2 and Database Explorer visit ASPNETDB.MDF at the same time!

Hello! I am working at a ASP.NET Project with has a sign-in area. All users (the aspnet_Membership and so on) are on an external SQL Server stored.The ConnectionString in the web.config looks like this:<add name="hspWerbung" connectionString="Persist Security Info=False;User ID=XXXXX;Password=XXXXX;Initial Catalog=HSPWERBUNG01;Data Source=SERVER_SQL_02STOCKHOLM" providerName="System.Data.SqlClient" />Is there any way to create a ConnectionString without the User ID and without the password?When i want to reach my site on the web (not with http://localhost/...) , i can't do it with "Integrated Security=True", because there will be no user, or?
Hay, I have a problem with this connectionstring.Dim myConnection As New Data.OleDb.OleDbConnection("Provider=SQLNCLI;Data Source=whatever-ja4lbqsqlexpress;Initial Catalog=Account;Integrated Security=SSPI;")I use this code to receive a value on a specific query Public Sub readdata(ByVal myconnectionstring As String) Dim mySelectQuery As String = "SELECT UserName, Password FROM TAccount WHERE UseName = '" & TextBox1.Text & "'; and Password = '" & TextBox2.Text & "';"

End While myreader.Close() myConnection.Close()
End Sub But when it execute i receive this exeption Login timeout expiredAn error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections.SQL Network Interfaces: Error Locating Server/Instance Specified [xFFFFFFFF]. Is this mean that i can not make a connection to my sql server 2005.

I have completed a windows db app. I have saved the db files in the application/bin/ folder. The connectionstring that i am using is
Code:
sql Server =(local);Data Source=.SQLEXPRESS;DataBase=;Integrated Security=SSPI
say i wanted to install this app on my home computer, does not have sql express or anything installed. Now i want to use the application and it must read/write data from the sql db that was saved in the application/bin/ folder. what is the connectionstring then ?
can anyone please help ? what im trying to say is that the application must work independent from any SQL manager/express etc.
I have changed connection string property of connectionmanger at runtime and saved package.But my new connectionstring is not persisting, i am getting my old connection string after reload package .

app.SaveToDtsServer(package, null,
@"File SystemDupaco Load Next Best.dtsx", "CIRCLE");
Hi, does anyone knows where can i find all the values that support the connectionstring??? since the connectionstring uses the "server=local;database=nortwind;UID=me...."
etc. are there more parameteres to specify ?? which one of them is not REALLY important?, where can i find a list or something about it??
When I create typed datasets (for SQL Everywhere db) using the VS designer, I get a connectionString like Data Source =".App_DataDb1.sdf" added to the settings file by the designer. This works fine in the designer but not at runtime. If I replace the settings value to Data Source ="|DataDirectory|App_DataDb1.sdf" then it works fine at runtime but breaks the designer. I looked at the typed dataset designer generated code & it creates a SqlCeConnection object which supports |DataDirectory| macro. So, how can I get the designer & runtime to agree on a connectionString. I guess I can create a partial class for the table adapters & force a connectionString at runtime via a constructor overload, but, is that my only option?
Btw, the error I get at runtime when using the designer generated connectionString is: "The path is not valid. Check the directory for the database."
hi, I'm having this application using the express way to create the dategridview by having the query string builder. However, my computer recently crashed and I have no idea to change the connection string. so when I load the whole windows application, I am unable to view the information that are supposed to be in the datagridview. however, it returned an exception. after finding out the main culprit, I realised that the database is using the old sql server's login. since it is using the old database's login, therefore it is unable to log the information into the datagrid view. Please help! Thanks.
Hi all, I want to connect to an SqlServer database and I have given the connectionstring on an WinXP computer as Dim ConnectionString As String = "server='localhost'; trusted_connection=true; Database='domains'" Now, when I copied the files to another computer which is Win 2003 Server, I had to give the connectionstring as Dim ConnectionString As String = "workstation id=INFO0;packet size=4096;integrated security=SSPI;data source=INFO0;persist security info=False;initial catalog=domains" Now, I want to upload the files to a website called "BrowseNow.com". What should be the connectionstring when the files are being uploaded to the server. I want the public to read from and write to this database tables. Is there anything I should do witht the SQL Server Enterprise Manager? Thanking you in advance, Tomy
In short, I have a couple grid views on a page that are used for editing as well as sorting, etc. The grids are setup to use the SqlDataSources. I'm trying to deploy this to a server environment for different instances (test,cert,prod) and am trying to set the ConnectionString for the SqlDataSource in the code behind (Page_Load()). Everything works well, except, I get an error message that says the "ConnectionString Property Has Not Been Initialized." Its a javascript alert coming up on top of the grid view. Here is how I'm trying to set the ConnString in the Page_Load():this.EmployeeTimeCardDataSource.ConnectionString = ConfigurationManager.ConnectionStrings[connStr].ConnectionString; Here is an example of the DataSource.<asp:SqlDataSource ID="EmployeeTimeCardDataSource" runat="server" SelectCommand="sp_Select_Managers_Employees_List" SelectCommandType="StoredProcedure"> <SelectParameters> <asp:SessionParameter Name="CurrentUser" SessionField="User" Type="String" /> </SelectParameters></asp:SqlDataSource>
I am getting an error message that says that my connection string has not been intialized I have initialized it. Dim AirliquidiConn As New SqlClient.SqlConnection(ConfigurationManager.AppSettings("AirliquidiDatabase")) Any suggestions??
Hi all This is the code in my web.config file. <appSettings> <add key="ConnectionString" value="server=127.0.0.1;database=testdb;uid=sa;pwd=sa"/> </appSettings> When I'm connecting to the sqlserver database,the page shows that The ConnectionString property has not been initialized. The code that I used to get the "ConnectionString" as belows using System.Configuration; protected static string connectionString =ConfigurationSettings.AppSettings["ConnectionString"]; public static object GetSingle(string SQLString,params SqlParameter[] cmdParms) { using (SqlConnection connection = new SqlConnection(connectionString)) { using (SqlCommand cmd = new SqlCommand()) { try { PrepareCommand(cmd, connection, null,SQLString, cmdParms); object obj = cmd.ExecuteScalar(); cmd.Parameters.Clear(); if((Object.Equals(obj,null))||(Object.Equals(obj,System.DBNull.Value))) { return null; } else { return obj; } } catch(System.Data.SqlClient.SqlException e) { throw new Exception(e.Message); } } } }
These code works well on my machine.When running on my colleague's machine ,the page show that exception. Any ideal?
I have a datasource on my ASP.NET 2.0 control I want to make dynamic. I have 6 different connection strings in my web.config file and want to change the connection with the selection in dropdownbox. Here is my VB code:Protected Sub GetDatabase(ByVal intDb As Integer) Select Case intDb

My IT dept set up an SQL db on a server for me and I am connected to it through a port. They told me I had to create my tables through an MS Access adp, which I have done. I am using VWD Express and am trying to create a login page using usernames and pw's from a db table. I am connected (at least the db Explorer tab shows I am) to the MS Access adp and can drop a GridView from my Employees table from it onto a page and get results. I keep getting the "ConnectionString property not initialized" error message pointing to my sqlConn.Open() statement and cannot figure out why. I have looked at hundreds of posts but can't seem to find anything that works. If someone could point me to some post or website that could explain connecting to a SQL db through a port or whatever you think I need to learn to get this fixed I would appreciate it.

(e.g. do I need to define DataSource or Initial Catalog or AttachDBFileName and the rest? What does it do exactely?)Also: I have registered my server as "MyServer" is that the alias I need/can use in my connectionstring?If someone could explain me the above questions it would be of GREAT help!!
Hello, I have just begun my first web application in vs 2005. I have a done a bit of coding in VS 2003. I have some list boxes on the page that use an ObjectDatasource that I set up with the wizard--and they work well and connect to SQL server. But I wanted to re use some of my old code for another list box on the page and put code in myself. Dim MyConnection As SqlConnection = New SqlConnection(ConfigurationManager.AppSettings("CONN_DATAConv")) Dim ProcConnection As SqlConnection = New SqlConnection(ConfigurationManager.AppSettings("CONN_DATAConv")) Dim myCommand As New SqlCommand(CommandText, MyConnection) MyConnection.Open() ProcConnection.Open() Here is what is in the web.config <configuration xmlns="http://schemas.microsoft.com/.NetConfiguration/v2.0"> <appSettings/> <connectionStrings> <add name="DataConvConnectionString_gisad" connectionString="Data Source=PWDGIS4;Initial Catalog=DataConv;Persist Security Info=True;User ID=gisad;Password=erv11new" providerName="System.Data.SqlClient" />
<add name="CONN_DATAConv" connectionString="Data Source=PWDGIS4;Initial Catalog=DataConv;Persist Security Info=True;User ID=gisad;Password=erv11new" providerName="System.Data.SqlClient" /> </connectionStrings> Please note that I canged the connection string call from ConfigurationSettingsAppSettings that was in vs 2003 But the connections won't open. Any help would be greatly appreciated.
Hello all. I created an app locally with VWD Express and moved it to to our server but I am getting the following error... An attempt to attach an auto-named database for file D:WebApp_DataSurvey.mdf failed. A database with the same name exists, or specified file cannot be opened, or it is located on UNC share. This is the connectionstring from the web.config file used on the server. I did not change anything from the local copy. <connectionStrings> <add name="SurveyConnectionString1" connectionString="Data Source=.SQLEXPRESS;AttachDbFilename=|DataDirectory|Survey.mdf;Integrated Security=True;User Instance=True" providerName="System.Data.SqlClient" /> </connectionStrings> What settings do I need to change in order for this to work? Any advice is appreciated. Thanks.
Hi, I hav eplaced an expression for the flat file connection as below
@[User::FileDirectory] + @[User::FileName]
This is supposed to be used instead of the ConnectionString property of the flat file connection.
You can see that I have created two variables.
The variable @[User::FileDirectory] is set to the directory. i.e. I have hardcoded the path to it and assigned it to this variable.
The variable @[User::FileName] is picked up automatically.
The question is:
When I go to the properties of the flat file connection, I delete the value inside the connectionstring property becuase there is now the expression which is set to the connectionstring. But when I come back to this property then I am not sure why the connectionstring property gets populated with the directory that I hardcoded to the variable.
