  • netcon.h not found with mingw?

    - by cftmon
    I am using the mingw(4.4.0) compiler that is included with QT4 and my IDE is netbeans 6.9. i noticed that i can't find netcon.h when i try to include it.I need netcon.h because i need some kind of API to bring up/down a network adapter,and after some googling i found that netcon.h is most commonly used. Linking netcon.h directly from the microsoft sdk produces lots of errors.Or is there some other library to alows me to reset an adapter, or i had to visual C++ completely to solve this problem?

  • Interesting issue with ScriptManager timeout value happens only in win2k machines

    - by jg
    When I set the Asyncpostbacktimeout value to a large value like 3600000000, the scriptmanager throws a timeout exception (it throws the error almost immediately after user action which triggers ajax request, so it is not timing out because the server is not responding). If I reset this value to some sane number like 3600 or even 36000, it works fine. AJAx content is getting updated in the page. This weirdness happens only in windows 2000 machines and does not happen in XP machines Any thoughts ?

  • WITH statement in Java

    - by Mike Clark
    In VB.NET there is the WITH command that lets you omit an object name and only access the methods and properties needed. For example: With foo .bar() .reset(true) myVar = .getName() End With Is there any such syntax within Java? Thanks!

  • protobuf-net NOT faster than binary serialization?

    - by Ashish Gupta
    I wrote a program to serialize a 'Person' class using XMLSerializer, BinaryFormatter and ProtoBuf. I thought protobuf-net should be faster than the other two. Protobuf serialization was faster than XMLSerialization but much slower than the binary serialization. Is my understanding incorrect? Please make me understand this. Thank you for the help. Following is the output:- Person got created using protocol buffer in 347 milliseconds Person got created using XML in 1462 milliseconds Person got created using binary in 2 milliseconds Code below using System; using System.Collections.Generic; using System.Linq; using System.Text; using ProtoBuf; using System.IO; using System.Diagnostics; using System.Runtime.Serialization.Formatters.Binary; namespace ProtocolBuffers { class Program { static void Main(string[] args) { string XMLSerializedFileName = "PersonXMLSerialized.xml"; string ProtocolBufferFileName = "PersonProtocalBuffer.bin"; string BinarySerializedFileName = "PersonBinary.bin"; var person = new Person { Id = 12345, Name = "Fred", Address = new Address { Line1 = "Flat 1", Line2 = "The Meadows" } }; Stopwatch watch = Stopwatch.StartNew(); watch.Start(); using (var file = File.Create(ProtocolBufferFileName)) { Serializer.Serialize(file, person); } watch.Stop(); Console.WriteLine(watch.ElapsedMilliseconds.ToString()); Console.WriteLine("Person got created using protocol buffer in " + watch.ElapsedMilliseconds.ToString() + " milliseconds " ); watch.Reset(); watch.Start(); System.Xml.Serialization.XmlSerializer x = new System.Xml.Serialization.XmlSerializer(person.GetType()); using (TextWriter w = new StreamWriter(XMLSerializedFileName)) { x.Serialize(w, person); } watch.Stop(); Console.WriteLine(watch.ElapsedMilliseconds.ToString()); Console.WriteLine("Person got created using XML in " + watch.ElapsedMilliseconds.ToString() + " milliseconds"); watch.Reset(); watch.Start(); using (Stream stream = File.Open(BinarySerializedFileName, FileMode.Create)) { BinaryFormatter bformatter = new BinaryFormatter(); //Console.WriteLine("Writing Employee Information"); bformatter.Serialize(stream, person); } watch.Stop(); Console.WriteLine(watch.ElapsedMilliseconds.ToString()); Console.WriteLine("Person got created using binary in " + watch.ElapsedMilliseconds.ToString() + " milliseconds"); Console.ReadLine(); } } [ProtoContract] [Serializable] public class Person { [ProtoMember(1)] public int Id {get;set;} [ProtoMember(2)] public string Name { get; set; } [ProtoMember(3)] public Address Address {get;set;} } [ProtoContract] [Serializable] public class Address { [ProtoMember(1)] public string Line1 {get;set;} [ProtoMember(2)] public string Line2 {get;set;} } }

  • Remove stateful EJB bean in client

    - by palto
    I'm currently learning EJB and as I understand when client gets a stateful session bean the server keeps it in memory(or passivates it) until the client removes the bean. Pretty simple, except nowhere I have seen any examples of how the client can actually remove the bean. How do you do that other than shutting down your client application? Or do I just have to implement a reset method in all my stateful beans if I want to start over?

    - by Parth
    how to implement a counter in label which decrements every time page is loaded in asp.net(vb)? It would be better if that counter value is accessed from and updated into database.. I've tried this on buttonclick but the value is reset automatically to intial value everytime as the button is insert and page is reloaded Protected Sub InsertButton_Click(ByVal sender As Object, ByVal e As System.EventArgs) Dim entries As Label = FindControl("label1") entries.Text = entries.Text - 1 End Sub

  • Is session destory not enough to clean the session

    - by Kamo
    When the user clicks a logout button, I connect to a script that simply does this session_destroy(); session_start(); I thought this would be enough to reset all $_SESSION variables such as $_SESSION['logged'] and $_SESSION['username'] but when I load the page again, it automatically logs me in as if the session is still active.

  • JQuery validation not working for checkbox group

    - by Chris Halcrow
    I'm having trouble getting JQuery validation to work with a set of checkboxes. I'm generating the checkboxes using an ASP.NET checkboxlist, and I've used JQuery to set the 'name' attribute to the same thing for each checkbox in the list. Here's the code that gets written to the browser. I'm setting the 'validate' attribute on the 1st checkbox to set the rule that at least one checkbox must be selected. The JQuery validation works for all other elements on the form, but not for the checkbox list. I'm also using a JQuery form wizard on the page which triggers validation for each 'page' of the form, so I don't have control over how the validation is called. <input id="ContentPlaceHolder1_MainContent_AreaOfInterest_0" class="ui-wizard-content ui-helper-reset ui-state-default" type="checkbox" value="Famine" name="hello[]" validate="required:true, minlength:1"> <label for="ContentPlaceHolder1_MainContent_AreaOfInterest_0">Famine</label> <br> <input id="ContentPlaceHolder1_MainContent_AreaOfInterest_1" class="ui-wizard-content ui-helper-reset ui-state-default" type="checkbox" value="Events Volunteer" name="hello[]"> <label for="ContentPlaceHolder1_MainContent_AreaOfInterest_1">Events Volunteer</label> Any ideas on what's going wrong? There are lots of examples of JQuery scripts that will do the validation, however I'm trying to avoid this as I'm generating the checkboxlist server side by a custom control so that it can be re-used across different pages that may or may not have JQuery enabled. I'm trying to enable the JQuery validation whilst being as unobtrusive as possible, so that pages will still work even if JQuery is disabled. Here are the relevant JQuery inclusions and JQuery initialisation script for the form wizard. I'm not using any initialisation code for JQuery validation: <script type="text/javascript" src="../js/formwizard/js/bbq.js"></script> <script type="text/javascript" src="../js/formwizard/js/jquery.form.js"></script> <script type="text/javascript" src="../js/formwizard/js/jquery.form.wizard.js"></script> <script type="text/javascript" src="../js/formwizard/js/jquery.validate.js"></script> <script type="text/javascript"> $(document).ready(function () { $("#form1").formwizard({ validationEnabled: true, focusFirstInput: true }); }); </script>

  • Clear form button in HTML...do we really need this?

    - by craigmoliver
    I usually add the clear form button to HTML forms by default, but tonight I had what alcholics call a "moment of clarity". Why the hell do we add this? In all my years of using the internet I have never gotten to the end of the form and thought "crap!, I screwed up, I need to reset this!". Is this button actually necessary or a hold over from another time?

So if i change the web service to ssl i always get a connection reset (101). I tried several ports 80,443,9999 with the same outcome. What is the error?

  • SQL 2005 - any way to restore/copy a diagram?

    - by NealWalters
    I used the Redgate packager (ran MSI) to reset all the data in my database (i.e. I deleted everything, and let it build the new database). Unfortunately, I discovered that it didn't retain my diagrams, which has a nice arrangement and several annotations. Is there any way to copy/migrate/script the diagram from one database to another (the databases have identical structures). Thanks, Neal Walters

  • Little more help with writing a o buffer with libjpeg

    - by Richard Knop
    So I have managed to find another question discussing how to use the libjpeg to compress an image to jpeg.

I've tried meddling with it but I am not sure how to do it. I I just replace this line: jpeg_stdio_dest(&cinfo, outfile); It's not going to work. There is more stuff that needs to be changed a bit in that function and I am being a little lost from all those pointers and memory management.

  • I'm having trouble traversing a newly appended DOM element with jQuery

    - by culov
    I have a form that I want to be used to add entries. Once an entry is added, the original form should be reset to prepare it for the next entry, and the saved form should be duplicated prior to resetting and appended onto a div for 'storedEntries.' This much is working (for the most part), but Im having trouble accessing the newly created form... I need to change the value attribute of the submit button from 'add' to 'edit' so properly communicate what clicking that button should do. heres my form: <div class="newTruck"> <form id="addNewTruck" class='updateschedule' action="javascript:sub(sTime.value, eTime.value, lat.value, lng.value, street.value);"> <b style="color:green;">Opening at: </b> <input id="sTime" name="sTime" title="Opening time" value="Click to set opening time" class="datetimepicker"/> <b style="color:red;">Closing at: </b> <input id="eTime" name= "eTime" title="Closing time" value="Click to set closing time" class="datetimepicker"/> <label for='street'>Address</label> <input type='text' name='street' id='street' class='text' autocomplete='off'/> <input id='submit' class='submit' style="cursor: pointer; cursor: hand;" type="submit" value='Add new stop'/> <div id='suggests' class='auto_complete' style='display:none'></div> <input type='hidden' name='lat' id='lat'/> <input type='hidden' name='lng' id='lng'/> ive tried using a hundred different selectors with jquery to no avail... heres my script as it stands: function cloneAndClear(){ var id = name+now; $j("#addNewTruck").clone(true).attr("id",id).appendTo(".scheduledTrucks"); $j('#'+id).filter('#submit').attr('value', 'Edit'); $j("#addNewTruck")[0].reset(); createPickers(); } the element is properly cloned and inserted into the div, but i cant find a way to access this element... the third line in the script never works. Another problem i am having is that the 'values' in the cloned form revert back to the value in the source of the html rather than what the user inputs. advice on how to solve either of these issues is greatly appreciated!
