Bug in Socket.Connected property

Posted By:      Posted Date: September 18, 2010    Points: 0   Category :.NET Framework
Hi!I've built a server which is listening to port 55.I run the current code: (VB.NET) Code Block Imports System.NetImports System.Net.SocketsModule Module1    Sub Main()        Dim sck As Socket = New Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp)        Dim myip As IPAddress = IPAddress.Parse("")        Dim myep As EndPoint = New IPEndPoint(myip, 55)        sck.Connect(myep)        Console.ReadKey() 'After this click I manually close the server        Console.WriteLine("Connected: {0}", Con(sck))        Console.ReadKey() 'Again...        Console.WriteLine("Connected: {0}", Con(sck))    End Sub    Public Function Con(ByRef Client As Socket) As Boolean        Try            Dim tmp(0) As Byte            client.Blocking = False            client.Send(tmp, 0, 0)        Catch e As SocketException            ' 10035 == WSAEWOULDBLOCK            If e.NativeErrorCode.Equals(10035) Then                Con = True            Else                Con = False            End If        End Try        Con = Client.Connected    End FunctionEnd Module As you can understand from the code, I connect to the server I've built, Waiting for the user to press 2 Enters in my program to show the state of the connection.It shows every Enter if the socket is connected (sck.Connected).So, I closed my server while they are connected, a

WPF / Silverlight tutorial: Visibility property and binding

abstract away the source of the connection string using a class with a static property.

ASP.NET provides a configuration system we can use to keep our applications flexible at runtime. In this article we will examine some tips and best practices for using the configuration system for the best results.

The element of a web.config file is a place to store connection strings, server names, file paths, and other miscellaneous settings needed by an application to perform work. The items inside appSettings are items that need to be configurable depending upon the environment, for instance, any database connection strings will change as you move your application from a testing and staging server into production.

Let's abstract away the source of the connection string using a class with a static property.

Get pixel format, raw format, property id list and property items image in VB.net - C#.net.

Jscript error: Object does not support property or method


 Hi, i have little knowledge on javascript but i need to use this code get from somewhere for a jquery to work.

I face this "Jscript runtime error: Object does not support property or method" whenever im trying to run this page.

In my experience, im get this error msg 9 out of 10 times i use javascript in my system.

Im using Microsoft Visual web developer 2008, i wonder if this is related to my problem, i not sure there is anything i need to add as reference or update anything.

But anyway, in short, i just couldn't use javascript code when using this development tool because of this sort of error.

Anyway, it happen that last time i tried use the same type of jquery code in another project and it seems to work well without an error.

But now when im try to use it again in this recent project i created, it come out with this error and i have no idea how to solve it even look through google and this forum.

It doesn't really seems like its the code problem itself although im not sure, because any javascript code just couldn't work.

So below is my code that i need to use.

<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js" ></script>
<script type="text/javascript" src=&quo

Is it possible to populate property choices from a database?


I'm creating my first server control, and have it working where I can set up an enum and the user can set a property's choices,  based off of that enum.  But I'd like it to pull records from a database and populate the list of choices for the property from a database.  This would allow me to add a new "Host System" to the database, and the other designers wouldn't have to get a new copy of the dll.



Custom Server Control Property not maintaining state


I have created a server control consisting of a TextArea and a div under it.  My goal is to create my own asp:TextArea type control.  the div is for a Character count of the text area and seems to work ok but i added a CharacterCountVisible property to the control that is always returning true.  See Proptery definition below


<Bindable(False), Category("Appearance"), DefaultValue("True"), Localizable(True)> Property CharacterCountVisible() As Boolean
        Return _CountBoxVisible
    End Get
    Set(ByVal value As Boolean)
        _CountBoxVisible = value
    End Set
End Property

Note the _CountBoxVisible variable is define inside the class as :

Dim _CountBoxVisible as Boolean = True

What I am trying to do is give the user/coder the option to show/utilize the char count feature.  Can make it disappear with textarea1.CharacterCountVisible = False but setting it to true will not make it display.


What am i missing





Category attribute of user control property does not work correctly in categories tab.



I have a User Control (ascx) and a property which a want to display in my categories tab in Visual Studio in the category named "Styles".

[Category("Styles"), DefaultValue(""), Description("The value for formating something.")]
public String MyFormatProperty
set { /* the code for set */; }
get { /* the code for get */; }

And here is the problem: Actually I do not need a get, because I only have to set the property (write only property). But when I omit the get, the property is displayed in the "Misc" category in the categories tab in Visual Studio. Only when I code the get as well, then the property is displayed correctly in the "Styles" category in the categories tab in Visual Studio.

Does anybody know why? How can I display the category correctly only with set?

Thanks, S.

Intermittant error: "A connection attempt failed because the connected party did not properly respon



I'm having a doozy of a problem, and can't find a solution.  I have a WFC Web Service installed to a pair of servers, and accessed through a load balancer.  I am accessing the service from an ASP.NET client app, also via WCF.  The Client is not load balanced.

Need to know (the value of a) clientside property on the serverside


I need to know on the serverside, if a RadioButton has been disabled (by javascript) on the clientside.


The (serverside) Enabled property is not the same as the (clientside) disabled property. Using MyRadioButton.Attributes("disabled") doesn't do the trick either.


Any clue?

Using Dynamic Property inside Html Helper with Razor fires an error



I have the following with Razor:

@Html.GoogleAjax(View.GoogleAjaxKey, new String[,] { { "jquery", "1.4.2" } })

And the I get a strange error:

  'System.Web.Mvc.HtmlHelper<object>' has no applicable method named 'GoogleAjax' but appears to have an extension method by that name. Extension methods cannot be dynamically dispatched. Consider casting the dynamic arguments or calling the extension method without the extension method syntax.

What is strange is that it works fine using:

@Html.GoogleAjax("123", new String[,] { { "jquery", "1.4.2" } })

I tried the following code line:


And the key is displayed just fine so the problem is how I use the value of @View.GoogleAjaxKey into Html.GoogleAjax.

Do I need to change something on my Html Helper? Here it is:

    public static MvcHtmlString GoogleAjax(this HtmlHelper helper, String key, String[,] libraries) {
