DataSource Controls :: Unable To Alter Connection Timout Property?
Feb 22, 2010
Im using two stored procedures to write and update values in a SQL DB. Im using the SQLDatasource update method. When I run the webpage on my development server everything runs fine. When I try and run the web page on my Live server I get the following error :System.Data.SqlClient.SqlException: Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding This always takes 30 seconds to fail - and looking at google it seems that this is a connection timeout error.In my web.config file I have updated the connectionstring line to include a timeout setting :
When I open an ASP.NET 3.5 project using VWD2010, I get a prompt error message,"The connection property in the web.config file is missing or incorrect.The connection string from the .dbml file has been used in its place."however, my project works successfully.
I am trying to setup my page with a drop down which value comes from one SQL query and item list comes from another SQL query to the same database...
what I want to do is:
read 1 line from bugs table. this line includes a projectid which will be the value of the drop down. I also read the projects table for active projects/id and load this as drop down items....
using (SqlConnection conn = new SqlConnection(ConfigurationManager.ConnectionStrings["ConnectionString"].ConnectionString)) { conn.Open(); using (SqlCommand bug = new SqlCommand( "SELECT bugs.id, bugs.projectid, bugs.typeid, bugs.subtypeid, bugs.version, bugs.summary, " + "users.email AS creator, bugs.createddate, bugs.text, bugs.closeddate, bugs.history " + "FROM bugs INNER JOIN users ON bugs.creatorid = users.id WHERE (bugs.id = @idd)", conn)) { bug.Parameters.AddWithValue("idd", Request.QueryString["ID"]); try { SqlDataReader reader = bug.ExecuteReader(); if (reader.Read()) { String projectid = reader[1].ToString(); // read project name list... using(conn) using (SqlCommand projects = new SqlCommand("SELECT name, id FROM projects WHERE active=true")) try { SqlDataReader pr = projects.ExecuteReader(); // This line causes the exception... what am I doing wrong? while (pr.Read()) project.Items.Add(new ListItem(reader[0].ToString(), reader[1].ToString())); } catch { }
I have the following code that I wasnt to alter the Dataset before it is bound to the dropdown list.
[Code]....
What I would like to do is ALTER the dataset for the Parent (dropdown list - ddlRT). I need to format and disable certain topics. I have a script I create before I added the datarelations.
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 need to change a user's role in my application. Therefore I need to know the correct syntax in code behind to alter a user's role; i.e. string sql = "ALTER TABLE ...etc". I'm not sure how to implement this at all. Is it similar to the INSERT INTO query used in code behind, where we define the parameters etc?
I have a table that contains image data type and has more than 20,000 records.I want to change its file group to the new file group. I tried to change it using table designer, but everytime I wanted to save it, it occured an error with this message:
[Code]....
Does anyone know how to change file group using Alter Table query? I'm using SQL Server 2005.
I am using SQL SERVER 2008 database. I have a table Customers in which the CustomerID column is had datatype INT intially but due to increase in Customers the number range is exceeding which may cause error arithmetic overflow of data. Hence I thought to modify the datatype from INT to BIGINT and wrote an alter script but when I ran the script it failed. Hence provide me in creating alter script for the updating the datatype of the primarykey column for the Customers table.
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).
I have VS 2010 professional. I am trying to open "ASP.Net Configuration" through Project -> ASP.Net Configuration.
It pops up the Notification about the ASP.Net Development Server localhost but doesn't open ASP.Net Configuration in the default browser.I clicked on the Root Url (by double clicking on the 'development server' at the right bottom from Notification Manager).
It throws following error
"An error was encountered. Please return to the previous page and try again."
Clicking on "How do i use this tool".It opened page with error.
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 am trying to create connection using OLEDB connection in my app. but i am not able to create the connection as in datasource i want to use Server.mappath, but cudn't find the right method to use it. i am trying to make connection with Access database file. following is code i have tried:
string path = Server.MapPath("~/uploadaccess/Production.mdb"); string ConnectionString = @"Provider=Microsoft.Jet.OLEDB.4.0; Data Source=" & Server.MapPath("~/uploadaccess/Production.mdb")&";"; and also OleDbConnection myConnection = new OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" & path&";"); and tried this OleDbConnection myConnection = new OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" & Server.MapPath("~/uploadaccess/Production.mdb"));
and this is the error i am getting:
Operator '&' cannot be applied to operands of type 'string' and 'string'
Traditionally with an Object Data Source, the wired up class will have its public properties available for binding (i.e. Gridview columns, etc.) which works well. But what if one of my wired up business objects has a property that is an object itself; can I drill down to a property on that object property and still use it?
So in additiona to the traditional:MyBusniessObject.OrderID...I want to use:MyBusniessObject.Customer.NameID Your 1st response might be to just wire up the 'Customer' class, but I need properties both on 'MyBusinessObject'and 'Customer'. I do not think this can be done, as the ODS will not display properties on an object instance property. I have tried manually typing in the drilled down value as well, but that wasn't a success either.
I am storing a custom "Organisation" object as a session variable. One of the properties of the Organisation object is "OrganisationID" (integer). I have a DataSource that requires a parameter value to run, and I want to use a SessionParameter to populate this. In a previous version, I stored the OrganisationID directly as a session variable. In that case, I could easily access it like this:
[Code]....
However, how do I now access the OrganisationID property of an "Organisation" type session variable (called "Organisation")? I have tried this, which does not seem to work: <asp:SessionParameter Name="OrganisationID" SessionField="Organisation.OrganisationID" Type="Int32" />
In some posts I have read on other forums, those with database connection problems (I am thinking about Access) sometimes get the error: 'Connection property has not been initialized' which might translate as 'you have not kick-started your connection'. One reason for that, according to a number of replies I have come across, is that 'you have not set the connection property of the command object' ('you have not told command how to connect').
So would something like this:
Code: Dim conn As New OleDbConnection Dim OleDbConnection As New OleDbConnection Dim cmd As New OleDbCommand conn.ConnectionString = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=|DataDirectory|myDatabase.mdb;" conn.Open() cmd = New OleDbCommand("SELECT strName FROM school WHERE strName=@strName", conn) cmd.Parameters.AddWithValue("@strName", UserName.Text) cmd.Connection = conn cmd.ExecuteNonQuery() conn.Close()
a) initialise the connection property and b) set the connection property of the command object?
i have an asp page through which i want to access FTP server And retrieve data (only file properties )from there and get it in excel (or just display it on the browser)is there any way i can keep it simple and acess the data from the server ???
I am getting error ExecuteReader: Connection property has not been initialized. below is the code i am using.
SqlDataReader oReader = new SqlDataReader(); string sSQL = @" WITH TAB_CTE AS ( SELECT fbominum, fbompart, fparinum, flevel, fsono FROM sodbom WHERE fbompart= @fbompart and fsono = @fsono UNION ALL SELECT e.fbominum, e.fbompart, e.fparinum, e.flevel, e.fsono FROM sodbom e INNER JOIN TAB_CTE ecte ON ecte.fbominum = e.fparinum where e.fsono = @fsono ) SELECT * FROM TAB_CTE where fbompart <> @fbompart "; SqlCommand oCommand = new SqlCommand(sSQL, this._connection); oCommand.CommandType = System.Data.CommandType.Text; oCommand.Parameters.Add("@fbompart", ItemSODBOM.fbompart); oCommand.Parameters.Add("@fsono", ItemSODBOM.SONO); oReader = oCommand.ExecuteReader();//Here I am getting error
The attached code, the oledb part, is giving me a blank web page saying it cant connect on my local dev server. I have another app with the same code, in fact I copied it and changed the db names. The one I copied from works fine.
