What Different Are There Between ConnectionString (Part 1) And ConnectionString (Part 2) In Web.config

Apr 12, 2006

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!
 
--------------------------------------Part 1------------------------------------------------------------------------<add name="MyConnect" connectionString="Data Source=.SQLExpress;Integrated Security=True;User Instance=True;AttachDBFilename=|DataDirectory|ASPNETDB.MDF"          providerName="System.Data.SqlClient" />  --------------------------------------Part 1------------------------------------------------------------------------
--------------------------------------Part 2------------------------------------------------------------------------<add name="MyConnect"  connectionString="Data Source=CCWWSQLEXPRESS;Initial Catalog=ASPNETDB.MDF;Integrated Security=True;User Instance=True;AttachDBFilename=|DataDirectory|ASPNETDB.MDF"     providerName="System.Data.SqlClient" />--------------------------------------Part 2------------------------------------------------------------------------

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.

SQL Everywhere ConnectionString Problems

Jul 26, 2006

<VS2005, SQL Everywhere CTP>

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."

Change Connectionstring For Dataset

Jul 25, 2006

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.

Why ConnectionString Varies On Different Servers.?

Jan 8, 2007

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

The ConnectionString Property Has Not Been Initialized

Jul 30, 2007

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>

The ConnectionString Property Has Not Been Initialized

Jan 25, 2008

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.

Dynamic ConnectionString For SqlDataSource

Mar 20, 2008

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

Case 1 ' Americas
srcCustomers.ConnectionString = "RWSqlServer"
Exit Sub
Case 2 ' Asia
srcCustomers.ConnectionString = "SGSqlServer"
Exit Sub
Case 3 ' Australia
srcCustomers.ConnectionString = "SYSqlServer"
Exit Sub
Case 4 ' Canada
srcCustomers.ConnectionString = "MSSqlServer"
Exit Sub
Case 5 ' EMEA
srcCustomers.ConnectionString = "NCSqlServer"
Exit Sub
Case 6 ' NE
srcCustomers.ConnectionString = "RUSqlServer"
Exit Sub
End Select
End SubProtected Sub ddlBusinessUnit_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs)

If (ddlBusinessUnit.SelectedIndex = 0) Then
panUser.Visible = False
panDistributor.Visible = False
panEndUser.Visible = False
GetDatabase(ddlBusinessUnit.SelectedIndex)
lblDb.Text = ddlBusinessUnit.SelectedIndex.ToString
Else
 
panUser.Visible = True
End If
End Sub
Here is my ASP.NET code:<asp:SqlDataSource ID="srcCustomers" runat="server" SelectCommand="SELECT cm_addr + ' - ' + cm_sort AS [name], cm_addr, cm_sort FROM cm_mstr WHERE cm_type <> 'I'">
</asp:SqlDataSource><asp:DropDownList ID="ddlBusinessUnit"
runat="server"AutoPostBack="True"
OnSelectedIndexChanged="ddlBusinessUnit_SelectedIndexChanged">
<asp:ListItem Value="" Text="Select One"></asp:ListItem>
<asp:ListItem Value="1" Text="Americas"></asp:ListItem>
<asp:ListItem Value="2" Text="Asia"></asp:ListItem>
<asp:ListItem Value="3" Text="Australia"></asp:ListItem>
<asp:ListItem Value="4" Text="Canada"></asp:ListItem>
<asp:ListItem Value="5" Text="EMEA"></asp:ListItem><asp:ListItem Value="6" Text="NE"></asp:ListItem>
</asp:DropDownList>
What am I missing?  Do I need to reference the whole connection string or is there a way I can reference the "NAME" id in the web.config file for the connection string?

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. Web config:

The ConnectionString Property Has Not Been Initialized

Feb 5, 2006

I have installed SQL Server 2005 Express Edition.I have defined the connectionstring in my web.config as follows:
<connectionStrings><add name="MyDB" connectionString="Server=local;Provider=SQLOLEDB;Initial Catalog=Shop;Trusted_Connection=Yes;DataSource==.SQLExpress;AttachDBFilename=Data/MyDB.mdf" providerName="System.Data.SqlClient"/></connectionStrings>Here's my vb code:
Dim connStr As String = ConfigurationManager.ConnectionStrings("MyDB").ToString()Dim DBConnection As New SqlConnectionDim SQLCmd As New SqlCommand("SELECT * FROM tblMember WHERE UserName=@UserName", DBConnection)SQLCmd.Parameters.Add(New SqlParameter("@UserName", tbUserName.Text))DBConnection.Open()and on that last line I receive the error: The ConnectionString property has not been initializedNow, I have seen SO many different versions of a connectionstring that im totally confused!!I want to use windows authentication (I know thats better for security reasons).But I have difficulties understanding the attributes required (AND THEIR MEANING!) of the connectionstring. (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!!

The ConnectionString Property Has Not Been Initialized

Apr 19, 2006

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.

Changing ConnectionString Settings

Jun 5, 2006

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.

Connectionstring Gets Populated Unwillingly

Jul 26, 2007



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.

Many thanks
