  • Is it a good idea to close and open hibernate sessions frequently?

    - by Gaurav
    Hi, I'm developing an application which requires that state of entities be read from a database at frequent intervals or triggers. However, once hibernate reads the state, it doesn't re-read it unless I explicitly close the session and read the entity in a new session. Is it a good idea to open a session everytime I want to read the entity and then close it afterwards? How much of an overhead does this put on the application and the database (we use a c3p0 connection pool also)? Will it be enough to simply evict the entity from the session before reading it again?

  • How to batch retrieve documents with mongoDB?

    - by edude05
    Hello everyone, I have an application that queries data from a mongoDB using the mongoDB C# driver something like this: public void main() { foreach (int i in listOfKey) { list.add(getObjectfromDB(i); } } public myObject getObjFromDb(int primaryKey) { document query = new document(); query["primKey"] = primaryKey; document result= mongo["myDatabase"]["myCollection"].findOne(query); return parseObject(result); } On my local (development) machine to get 100 object this way takes less than a second. However, I recently moved the database to a server on the internet, and this query takes about 30 seconds to execute for the same number of object. Furthermore, looking at the mongoDB log, it seems to open about 8-10 connections to the DB to perform this query. So what I'd like to do is have the query the database for an array of primaryKeys and get them all back at once, then do the parsing in a loop afterwards, using one connection if possible. How could I optimize my query to do so? Thanks, --Michael

I find this: http://msdn.microsoft.com/en-en/library/ms144211%28v=VS.80%29.aspx that generate this event: http://msdn.microsoft.com/en-en/library/system.net.webclient.openreadcompleted%28v=VS.80%29.aspx I think this is what i need, but i don't have the WebClient class in my System.Net of CompactFramework 3.5.

  • Creating TCP network errors for unit testing

    - by Robert S. Barnes
    I'd like to create various network errors during testing. I'm using the Berkely sockets API directly in C++ on Linux. I'm running a mock server in another thread from within Boost.Test which listens on localhost. For instance, I'd like to create a timeout during connect. So far I've tried not calling accept in my mock server and setting the backlog to 1, then making multiple connections, but all seem to successfully connect. I would think that if there wasn't room in the backlog queue I would at least get a connection refused error if not a timeout. I'd like to do this all programatically if possible, but I'd consider using something external like IPchains to intentionally drop certain packets to certain ports during testing, but I'd need to automate creating and removing rules so I could do it from within my Boost.Test unit tests. I suppose I could mock the various system calls involved, but I'd rather go through a real TCP stack if possible. Ideas?

  • c# passing method names as the argument in a method

    - by Alan Bennett
    hi guys, I have a recuring method which shows up many times in my code its basically checking to make sure that the connection to the odbc is ok and then connects but each time this method is called it calls another method and each instance of the main method this one is different, as each method is about 8 lines of code having it 8 times in the code isnt ideal. so basically i would like to have just one method which i can call passing the name of the new method as an arguement. so basically like: private void doSomething(methodToBeCalled) { if(somthingistrue) { methodToBeCalled(someArgument) } } is this possible? thanks in advance

  • ASP.NET/VB/SQL: trying to insert data, getting error "no value given for required parameters"

    - by Sara
    I am pretty sure this is a basic syntax error, I am new at this and basically figuring things out by trial and error... I am trying to insert data from textboxes into an Access database, where the primary key fields in tableCourse are prefix and course_number. It keeps giving me the "no value given for one or more required parameters" error. Here is my codebehind: Protected Sub Wizard1_FinishButtonClick(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.WizardNavigationEventArgs) Handles Wizard1.FinishButtonClick 'Collect Data Dim myDept = txtDept.Text Dim myFirst = txtFirstName.Text Dim myLast = txtLastName.Text Dim myPrefix = txtCoursePrefix.Text Dim myNum = txtCourseNum.Text 'Define Connection Dim myConn As New OleDbConnection myConn.ConnectionString = AccessDataSource1.ConnectionString 'Create commands Dim myIns1 As New OleDbCommand("INSERT INTO tableCourse (department, name_first, name_last, prefix, course_number) VALUES (@myDept, @myFirst, @myLast, @myPrefix, @myNum)", myConn) 'Execute the commands myConn.Open() myIns1.ExecuteNonQuery() End Sub

  • breaking out from socket select

    - by kamziro
    I have a loop which basically calls this every few seconds (after the timeout): while(true){ if(finished) return; switch(select(FD_SETSIZE, &readfds, 0, 0, &tv)){ case SOCKET_ERROR : report bad stuff etc; return; default : break; } // do stuff with the incoming connection } So basically for every few seconds (which is specified by tv), it reactivates the listening. This is run on thread B (not a main thread). There are times when I want to end this acceptor loop immediately from thread A (main thread), but seems like I have to wait until the time interval finishes.. Is there a way to disrupt the select function from another thread so thread B can quit instantly?

  • Help to run it in the background

    Here's a simple python daemon I can't manage to run as a background process: #!/usr/bin/env python import socket host = '' port = 843 backlog = 5 size = 1024 s = socket.socket(socket.AF_INET, socket.SOCK_STREAM) s.bind((host,port)) s.listen(backlog) while 1: client, address = s.accept() data = client.recv(size) if data == '<policy-file-request/>\0': client.send('<?xml version="1.0"?><cross-domain-policy><allow-access-from domain="*" to-ports="*"/></cross-domain-policy>') client.close() It's a socket policy file server (you may have heard of the restiction Adope put on socket connection - http://www.adobe.com/devnet/flashplayer/articles/socket_policy_files.html); that works well when gets run like an "ordinary" process - "python that_server.py", - but I get problem to run it in the background. Running like so: "that_server.py &", - does not work.

  • mysqli::query returns true on SELECT statement

    - by Travis Pessetto
    I have an application that reads in one of its classes: public function __construct() { global $config; //Establish a connection to the database and get results set $this->db = new Database("localhost",$config["dbuser"],$config["dbpass"],"student"); $this->records = $this->db->query("SELECT * FROM major") or die("ERROR: ".$this->db->error); echo "<pre>".var_dump($this->records)."</pre>"; } My problem is that var_dump shows that $this->records is a boolean. I've read the documentation and see that the SELECT query should return a result set. This is the only query used by the application. Any ideas where I am going wrong?

  • Amazon EC2 multiple servers share session state

    - by Theofanis Pantelides
    Hi everyone, I have a bunch of EC2 servers that are load balanced. Some of the servers are not sharing session, and users keep getting logged in and out. How can I make all the server share the one session, possibly even using a partitionresolver solution public class PartitionResolver : System.Web.IPartitionResolver { private String[] partitions; public void Initialize() { // create the partition connection string table // web1, web2 partitions = new String[] { "192.168.1.1" }; } public String ResolvePartition(Object key) { String oHost = System.Web.HttpContext.Current.Request.Url.Host.ToLower().Trim(); if (oHost.StartsWith("10.0.0") || oHost.Equals("localhost")) return "tcpip=127.0.0.1:42424"; String sid = (String)key; // hash the incoming session ID into // one of the available partitions Int32 partitionID = Math.Abs(sid.GetHashCode()) % partitions.Length; return ("tcpip=" + partitions[partitionID] + ":42424"); } } -theo

  • How to do query auto-completion/suggestions in Lucene?

    - by Mat Mannion
    I'm looking for a way to do query auto-completion/suggestions in Lucene. I've Googled around a bit and played around a bit, but all of the examples I've seen seem to be setting up filters in Solr. We don't use Solr and aren't planning to move to using Solr in the near future, and Solr is obviously just wrapping around Lucene anyway, so I imagine there must be a way to do it! I've looked into using EdgeNGramFilter, and I realise that I'd have to run the filter on the index fields and get the tokens out and then compare them against the inputted Query... I'm just struggling to make the connection between the two into a bit of code, so help is much appreciated! To be clear on what I'm looking for (I realised I wasn't being overly clear, sorry) - I'm looking for a solution where when searching for a term, it'd return a list of suggested queries. When typing 'inter' into the search field, it'll come back with a list of suggested queries, such as 'internet', 'international', etc.

  • Order objects for Northwind Access database

    - by Artem Shnayder
    I need to build two objects: an OrderList and an Order. Using those two objects, I have to populate a DataGridView with a history of the orders. However, I am instructed not to use binding sources for the connection or other drag and drop controls. Unfortunately, from Google it seems like those are the most popular options for this type of problem. Can anyone point me in the right direction? I don't have much experience with C#. Thanks.

  • Traffic consumed by Team Foundation Server 2010

    - by micha12
    We are currently selecting a source control and issue tracking software, and are looking towards Team Foundation Server 2010. Some participants of our project often have slow Internet connection (for example during travel), and therefore it is important for us to have a source control system that does not consume too much traffic. I was unable to find information on traffic consumption when using TFS 2010. Does anyone has such info? Does TFS 2010 support traffic compression? Do other source control systems (like SVN, for example) produce less or more traffic than TFS 2010?

  • Getting search results from Twitter in php

    - by Mark Mayo
    I'm attempting to put together a little mashup with some twitter APIs. However, the whole area is new to me (I'm more of an embedded developer dabbling). And frustratingly, every tutorial I am trying in Php is either out of date, not doing what it claims to do, it or is broken. Essentially, I just want a nice bit of example code - say, an HTML file, a connection.js for the JQuery magic, and a php file - 'getsearch' which contains the relevant Curl calls to the API to just return the results for a given search term. Followed the tutorial to the letter at http://www.reynoldsftw.com/2009/02/using-jquery-php-ajax-with-the-twitter-api/ and even downloaded the guy's code and chucked it on my webserver, but it just seems to sit there. I'm relatively competent at php and html, but it's the Curl and the JQuery side of things which is new to me, and would appreciate any thoughts, links, or code suggestions. I've attempted reading the API - but even that seems sparse - and several links are broken to their own tutorials, so that's put me off a bit for now.

  • Visual-C++ Linker Error

    - by LordByron
    I have a class called MODEL in which public static int theMaxFrames resides. The class is defined in its own header file. theMaxFrames is accessed by a class within the MODEL class and by one function, void set_up(), which is also in the MODEL class. The Render.cpp source file contains a function which calls a function in the Direct3D.cpp source file which in turn calls the set_up() function through a MODEL object. This is the only connection between these two source files and theMaxFrames. When I try to compile my code I get the following error messages: 1Direct3D.obj : error LNK2001: unresolved external symbol "public: static int MODEL::theMaxFrames" (?theMaxFrames@MODEL@@2HA) 1Render.obj : error LNK2001: unresolved external symbol "public: static int MODEL::theMaxFrames" (?theMaxFrames@MODEL@@2HA) 1C:\Users\Byron\Documents\Visual Studio 2008\Projects\xFileViewer\Debug\xFileViewer.exe : fatal error LNK1120: 1 unresolved externals

  • MS SQL Server Dates Excel

    - by KillerSnail
    I have data this is linked from SQL Server into an excel document. The column format on the SQL Server is datetime2. When I get the data via an ODBC connection it comes across as a string? I tried using CAST(column AS DATE ) but that didn't work. I tried reformatting via CONVERT(VARCHAR(10), column, 103) as well but that didn't work. I tried retrieving the data via Microsoft query as well but that didn't work. At the moment I am using VBA code like: While (ActiveCell.Value <> "") ActiveCell.Value = DATEVALUE(ActiveCell.Value) ActiveCell.Offset(1,0).Activate Wend and looping through each column that needs this treatment but 100000 rows in multiple columns takes forever to loop through. Are there any alternatives?

  • SSIS web service task producing "object reference" error

    - by gfrizzle
    Our care management system uses a web service to import data. I've successfully executed one of its methods using soapUI, and now I want to replicate this with an SSIS 2008 web service task, but I'm running into a problem. I've created the "HTTP Connection Manager" successfully, and specified the location of the "WSDLFile", but when I go to the Input tab and select the Service from the dropdown (there is only one), I get an "Object reference not set to an instance of an object" error, and and the Method dropdown is empty. Any idea what this is trying to tell me?

  • ASP.NET web services leak memory when (de)serializing disposable objects?

    - by Serilla
    In the following two cases, if Customer is disposable (implementing IDisposable), I believe it will not be disposed by ASP.NET, potentially being the cause of a memory leak: [WebMethod] public Customer FetchCustomer(int id) { return new Customer(id); } [WebMethod] public void SaveCustomer(Customer value) { // save it } This flaw applies to any IDisposable object. So returning a DataSet from a ASP.NET web service, for example, will also result in a memory leak - the DataSet will not be disposed. In my case, Customer opened a database connection which was cleaned up in Dispose - except Dispose was never called resulting in loads of unclosed database connections. I realise there a whole bunch of bad practices being followed here (its only an example anyway), but the point is that ASP.NET - the (de)serializer - is responsible for disposing these objects, so why doesn't it? This is an issue I was aware of for a while, but never got to the bottom of. I'm hoping somebody can confirm what I have found, and perhaps explain if there is a way of dealing with it.

  • Is it possible to run a compiled program with Xcode on Mac OS X in FreeBSD? (Objective-C/Cocoa)

    - by Eonil
    Hi. I have a plan to build a web-site which running CGI made with Cocoa. My final goal is develop on Mac OS X, and run on FreeBSD. Is this possible? As I know, there is a free implementation of some NextStep classes, the GNUStep. The web-site is almost built with only strings. I read GNUStep documents, classes are enough. DB connection will be made with C interfaces. Most biggest problem which I'm concerning is linking and binary compatibility. I'm currently configuring FreeBSD on VirtualBox, but I wanna know any possibility informations about this from experts. This is not a production server. Just a trial. Please feel free to saying anything.
