Because You have mention about Ports and Sockets which is related with Windows Application.
ASP.NET is nothing to with Ports and Sockets. You server will be centralized and all client will access the same server.
If you are really searching for ASP.NET Chatting Application, Then also I will revert back to Google only.

This sort of application would be similar to any live chat application. When googling try the open source keyword as well hopefully it will bring you some nice stuff.

How to make bulk update using TableAdapter

Hi ,

I have a small requirement, which I am unable to complete.

I am having a gridview on the form, and the data is bined to the grid using ObjectDatasource that is inturn binding from a TableAdapter in the dataset.

I have all select,insert,update and delete commands specified.

When i click on update or insert or delete it is just working fine as it is intended to.

It is directly updating/inserting/deleting in the database.

My requirement now is it should not update directly in the database instead it should update the database on click of a "Save" button at the bottom of the page.

All the changes he had made till now in the grid should directly updated in the database at one shot.

I dont want to store in either in a variable or in a session. Because of the memory constraint.

Is there any efficient way. I have tried googling all around and one link I found which is similar is

http://social.msdn.microsoft.com/Forums/en-US/vbgeneral/thread/cac3ab15-9236-4e6a-9ec1-f3cd73c91641

The explanation is very clear but I need it with an example.

Thanks in advance.

The Guy is Talking about ado.net. If you use Wizards to do your Database work you will encounter problems like limitations. Now in your case you dont want to update the grid automatically as the user leaves the field but on a Button click when you will have your own custom code. As the guy explained in the msdn post you have read. it can be done. i have written an article before, but it was for a windows application and the aproach is the same check it out

Thank you, For ur reply.

The post was very nice, Once upon a time I also such BLL and Valueobject classes.

But as i started using Dataset, it seems to be it is providing me all the stuff.

Let me explain My requirement briefly.

I have a grdiview , I will update or delete or insert rows(using commandbuttons) in the gridview. But it should not be affected directly in database untill i click on save button(which is outside the grid).

Conditions to achieve this are:
1. Should not use variables or sessions
2. Must use object datasource and Dataset located in APP_CODE folder

I hope there must be easiest way. as part of this reasearch some where else I found xmlserialzation would help working on it. I will let you know once it is done.

I think this is simple

as you said all command objects have the values, meaning the insert, update, and delete. ok now what you can do remove the command statements from the Sqldatasource control and put them in a Button as you want outside the the Gridview and do your update this way

SqlDataSource1.Update()

SqlDataSource1.Delete();

Am not a fan of XML

This will help.

Hi Abhijit,

you are absolute right. but in our code project site some people

always make marking (comment) on other question). that's why we

have no option to right this. as a developer i know if we are clear

more then we can give our better to other.

Sorry, but my intention is not to use wrong words.

I think you didn't get me.what third party forum you are talking about.Every third party forum/tool or anything has diffrent way to integrate.

If you are saying like this means,you didn't do the proper homework for your requirement.First clear your requiement,get the details, design it,look for the third party controls that you require on internet and try to develop the application.nad if face some problem,post your question here.

Communicate between Applications using Httpcontext object.

22-Jul-09 23:27

I have two applications configured in IIS. I need to Pass some values from one application to other using HttpContext object.

I have tried out using

FormsAuthentication.SetAuthCookie("Hello", false)

which sets one value in the Httpcontext object which i m retrieving from other application through

HttpContext.Current.User.Identity.Name property.

Upto this all works fine but i need to pass more user data using Httpcontext object and retrive it in other application.

How can i do that?
Is it possible to pass more user data Using HttpConext Object or not....

Please help me out Frown | :(

Re: Communicate between Applications using Httpcontext object.

Actually, what is happening is simply a cookie being set on the client. SetAuthCookie establishes the user authentication cookie, which allows HttpContext.Current.User to be available.

If you want to application #2 to read application #1 data, you could have app#1 set a cookie that app#2 can then read.

I need to fetch the list of open windows, which all currently open in client machine. Though i did some finding and code is working in local web server, however this does not works if this hosted in remote machine.

I am trying to access the link (application hosted in remote server) in my local machine, and while doing so this does not return me list for currently opened windows.

What should i do to make this work? Here is the code sample i am using:-

using System;

{
const int MAXTITLE = 255;

private static ArrayList mTitlesList;

private delegate bool EnumDelegate(IntPtr hWnd, int lParam);

ExactSpelling = false, CharSet = CharSet.Auto, SetLastError = true)]

[DllImport("user32.dll", EntryPoint = "GetWindowText",
ExactSpelling = false, CharSet = CharSet.Auto, SetLastError = true)]
private static extern int _GetWindowText(IntPtr hWnd,
StringBuilder lpWindowText, int nMaxCount);

protected void Page_Load(object sender, EventArgs e)
{
string[] desktopWindowsCaptions = GetDesktopWindowsCaptions();
string tmpCaption=string.Empty;
foreach (string caption in desktopWindowsCaptions)
{
tmpCaption = tmpCaption + "@@@" + caption;
}
Response.Write(tmpCaption);
}

private static bool EnumWindowsProc(IntPtr hWnd, int lParam)
{
string title = GetWindowText(hWnd);
mTitlesList.Add(title);
return true;
}

/// <summary>
/// Returns the caption of a windows by given HWND identifier.
/// </summary>
public static string GetWindowText(IntPtr hWnd)
{
StringBuilder title = new StringBuilder(MAXTITLE);
int titleLength = _GetWindowText(hWnd, title, title.Capacity + 1);
title.Length = titleLength;

return title.ToString();
}

bool success = _EnumDesktopWindows(hDesktop, enumfunc, IntPtr.Zero);

if (success)
{
// Copy the result to string array
string[] titles = new string[mTitlesList.Count];

}
else

Yup that will happen because of the Asp.net nature.If you want this in client machine you have only one option that is ActiveX control... Smile | :)

As the code runs on the server it is returning you the open windows on the server, not the client PC. This distinction about where code runs is often overlooked but it is fundamental to understanding ASP.net. As the above post, you'd need ActiveX.

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
