Hmm in this forum i dont think its legal to buy products and you would hardly find anyone in your case.

You should try to develop it yourself and we will help you were u need. But first you have to try atleast Tnx.

Im having alot of trouble understanding what you're writing. I wasnt going to mention it incase you where from a non-english speaking country, but then i saw you're from the UK...please, if you want serious answers, please make an effort to be understood.

This isnt the forum to post requests like these, we have a separate Project Requests forum where your post should be moved soon enough.

Edit: You should also include something like a price idea. This is quite a large project so personally I wouldnt start working on it unless I knew what I'd be paid.
Do you have a dedicated server with some kind of database? You'd need that in order to store user information and alot other things.

[Skatebone]

What scale of project are you thinking on?
You could use basic server and client issues with Tcp not winsock xD

Hey,

There is an example in the CodeBank that shows how this can be done.

http://www.vbforums.com/showthread.php?t=325908

The only downside is that it is written in VB6, but it would give you an idea where to start.

Here are also a few links that might help you out as well:

Hope that helps!!

Hiii sorry for that inconvenience about my English.
and sorry when i posted this topic in wrong place

it would be gratefully if you can provide some information about requirements such as Server, Database, Application language, project schedule and plan.
I am sure I can give you variety of price quotations depends on your project.

by the way you really don't have to worry about design, i will manage this part by my self only i need a working server and client part

thx

You can find alot of snippets on the net bout client and server parts. Its relatively easy to send text from a client to client the hard part goes when you are sending files xD

i expect 200 members who will join straight after launching so that program shld be capable for this amount of clients and shld stay stable...

PS: im ready 2 buy things that are required for this project such as server and oda stuffs.


krishan

[Skatebone]

Er...200 people aint that easy :/ You will definetely need to buy a server. I suggest you manage to program a small application which works in a lan first. That would be a good start. Then all you have to do is bother in getting it public xD

[Skatebone]

Here is a small idea for a client:

Public Class Form1
    Private client As System.Net.Sockets.TcpClient
    Private Const BYTES_TO_READ As Integer = 255
    Private readBuffer(BYTES_TO_READ) As Byte
    Dim bob
    Dim Locip


    Private Sub doRead(ByVal ar As System.IAsyncResult)
        Dim totalRead As Integer
        Try
            totalRead = client.GetStream.EndRead(ar) 'Ends the reading and returns the number of bytes read.
        Catch ex As Exception
            'The underlying socket have probably been closed OR an error has occured whilst trying to access it, either way, this is where you should remove close all eventuall connections
            'to this client and remove it from the list of connected clients.
        End Try

        If totalRead > 0 Then
            'the readBuffer array will contain everything read from the client.
            Dim receivedString As String = System.Text.Encoding.UTF8.GetString(readBuffer, 0, totalRead)
            messageReceived(receivedString)
        End If

        Try
            client.GetStream.BeginRead(readBuffer, 0, BYTES_TO_READ, AddressOf doRead, Nothing) 'Begin the reading again.
        Catch ex As Exception
            'The underlying socket have probably been closed OR an error has occured whilst trying to access it, either way, this is where you should remove close all eventuall connections
            'to this client and remove it from the list of connected clients.
        End Try
    End Sub

    Private Sub messageReceived(ByVal message As String)
        bob = message
    End Sub
    Private Sub SendMessage(ByVal msg As String)
        Dim sw As IO.StreamWriter
        Try
            sw = New IO.StreamWriter(client.GetStream)
            sw.Write(msg)
            sw.Flush()
        Catch ex As Exception
            MessageBox.Show("Unable to connect!", "Connection", MessageBoxButtons.OK, MessageBoxIcon.Exclamation)
        End Try
    End Sub

    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        SendMessage(TextBox1.Text)
        TextBox1.Text = ""
    End Sub



    Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick
        If bob <> "" Then
            TextBox2.Text = TextBox2.Text & vbCrLf & bob
            bob = ""
        End If
        Try
            Me.Text = Locip & " connection state: " & client.Connected
        Catch ex As Exception
            Me.Text = Locip & " connection state: False"
        End Try

    End Sub

    Private Sub Button2_Click_1(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click

        Catch ex As Exception
            MessageBox.Show("Unable to connect!", "Connection", MessageBoxButtons.OK, MessageBoxIcon.Exclamation)
        End Try
    End Sub

    Private Sub Button3_Click_1(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button3.Click

            SendMessage(Locip & " has just diconnected with you.")
            Timer2.Enabled = True
        Catch ex As Exception
        End Try
    End Sub

    Private Sub Form1_FormClosing(ByVal sender As Object, ByVal e As System.Windows.Forms.FormClosingEventArgs) Handles Me.FormClosing
        e.Cancel = True
        On Error GoTo 0

nyway thx for ur code
will try soon

Krishan , J

[Skatebone]

Both but u need server aswell for it to work :P I have to go though for a while and got no time to look for the server somewhere in my pc. Atheist will help you if you provide some of your code and Ps: you need to edit the client i just copied and pasted and added some lines from my application. tnx

I would be interested in working on this project. But one cant just start writing an instant messenger application without basic requirements knowledge.
If you could describe everything this "system" should be able to do in detail, it'd be good.

lool as i used it to swear someone
btw "*****" is common word in uk / us to express something that is abnormal. ^^
nd aint mentioned something else..

nyway move to the topic

ye sure..

As i mentioned in previous posts.
I am expecting around 200 clients straight after launching and it will increase everyday/week/month atlease 1000 within next 2 months.

System should be a mixture of MSN and Yahoo
msn does not have a main window where all user can chat simulate.
1>our new chat shld have this function.(important)
2>each single user shld be able to see a list of "all registered user" (important)
Filetransfer - not reli needed for the first step
Offline MSg - needed
avatar - needed
hmm everything like msn but plus 1 and 2 and is needed

futureplan?
our clients are able to communicate with MSN/yahoo clients

now its your turn..
possible ? hard? easy? medium?
how long will it take? schedule, plan?
required things?
and your quotation

It is common, but is profanity - and is therefore not allowed on this site.

If you don't like that rule, you are free to leave. If you aren't willing to abide by the rule, you will leave whether you like it or not.

Krishan,

I have already said in my reply to your e-mail that I am intesred in developing this application. I had developed an Messenger client for my previous company and it was easily handling few hundred connections. Some of the features of that application are Contact list, tabs for multiple conversations, typing notifications, presence, rich text messages, emotions, announcements, avatar, etc.

As you already had look at my post Develop an Enterprise class Instant Messenger client in .NET, you know that I used Openfire as a Server developed by Ignite Realtime and developed client in VB.NET. Ignite Realtime also has a free open source client called Spark developed in Java. You can download it's source code from public svn of Download section. To modify it to suit your requirements, you have to be a master of Java. Trying to modify the souce code just for hobby is ok but since you are ready to pay then it sounds like you are willing to develop a serious application, may be for commercial purpose. If that is so then my suggestion would be to develop a fresh messaging client in .NET.

EDIT: It's also possible to communicate with MSN and Yahoo users from Ignite Realtime using IM gayways.
