2005 - Server / Client RTF Formatted Text Send / Receive
Jan 21, 2009
Instead of the send message text box and message display text box, I have replaced it with RichTextBox for text formatting (bold/italics/underline/font/color). The problem I am facing is when I format the text and click on send, then the text displayed on the message display box (txtMessageHistory) is unformatted. [Code] Rest of the code of client is related to formatting of the rich text boxes that is not relevant to my problem. I just need to transfer the formatted text from client to server and then back to the client the same way and display the message with text formatting.

how to create a client/server... But I couldn't... I don't want anything fancy. Just want the client to send the server 4 numbers, depending on the user's choice; after that, the server would turn off the pc, restart it, etc. It all depends on the number received. Is there a rather "simple" way to do it? If it's not to much trouble you could use Atheist's example. (Btw I don't understand the code and, yes, I've checked on [URL])

Hey guys, I am trying to send data from client to server (encrypted) and the string sent from the client is not the same as recieved from the server. I've been killing my brain for hours to get this to work but I cant manage. Im converting everything to Base64 string.
Client:
Public Sub SendMessage(ByVal msg As String)
Try
SyncLock myclient.GetStream
sw = New IO.StreamWriter(myclient.GetStream)

An currently writing a vb.net application to send and receive information from a client via telnet. Am using System.net.Sockets to do this. I can send data great and get data back is ok. So the Problem is in the command window after I telnet in to the server application, when i press the delete key the cursor moves back a character and doesn't delete the character, just over writes it and when I read the bytes in I get the deleted character and the ascii value for the delete key and then the replacement character. I have seen another telnet application that shows the deletion of characters in the Command window.

I have created a Client that can send and receive data via TCP sockets. The objects stored on the serverside are the *exact* same object used for the client. They use the same send and receive protocols.
Now, when i send a string from the server to the client , it does precisely what it should do. However when I send a string to the server.... I do receive the string as an equal length of NULL characters. I run the server and client locally.
Basicly what can influence the behaviour between two completely identical objects performing the exact same task? I wonder if there is some socketflag issue if the TCPlistener.accept function returns a completely different setup then the one I R used to.
(if it is of any interest, the send protocol is asynchronious)

i have been working on a chat program Server side and client side i have most of the features i was asked to put in but then once i got most of the bugs out i noticed something the server admin could send whispers and alerts to single users but then when you try do do it on the client side it wont work so i looked through it all and found my issue the user list on the client is only a list of the names in server hash table so i was wondering how do i send the hashtable and all of its data E.G. user connection information to the client so that it can send commands to individual users like the server side can
vb
Public clients As New Hashtable()
' This subroutine checks to see if username already exists in the clients
' Hashtable. If it does, send a REFUSE message, otherwise confirm with a JOIN.
[code]....
i tried to send the hashtable over the same method used to send the user names to the client but it cannot convert the hashtable to a string so that wont work so my question is How do i send the hash table to the user from the server then display the username on the client ??

I've solved part of the problem, but something I've just realised is the information just isn't getting through and EVERY example I find uses a Console type application and what about us people who don't wanna develop a Console application? I don't but nooooo they don't seem to understand that at MS and put one example which uses exactly that.

I have been reading through Atheists posts in regards to client-server and TCP client/server connection's. But how do i go about writing a program with 1 client and server where the client side creates a text file.Once the server sees there is a text file it connects and downloads it to itself or the client pushes the text file to the server.Once on the server i will read the text file and put its info into a sql db.

I have programmed a chat application in VB but as soon as I send any data from a client the server will send it to all. It should send a reply only to a particular client. This is the function I have used.

What code can I use to send a simple text file to someone else's computer and choosing a save location and vice versa from theirs and loading it into a rich text box in their application that they have open, and vice versa? Their application is the same as mine (sort of like how an instant messenger works-except it does not save, send, and load text files like I am aiming for)

What's the best way to do this without using FTP?
The client would need to be able to communicate with the server for several simple tasks, such as checking if the file on the client is different from the file on the server. Or issue a "create folder" command. And of course the file transfer itself.[code]...

I am facing problem in asynchronous socket communication.
1)I wanted to perform connect(from client to server) operation on enter button and send the data whatever client want to send and disconnect from server. And again client should get connect to server whenever client wanted to send data. this is the mechanism.
i.e how to reuse the socket.
2)Again Server should able to send the data to client.

I'm currently "trying" to make an app that gets a certain text from the client and sends it to a server and the server sorts it out every text that he gets from the client into a different label every time he gets a text from a client. For example :
Client1 sends certain text to Server and server puts it in label1.text
Client2 Sends different text to Server and server puts it in label2.text
Client3 sends different text than 1 and 2 to Server and server puts it in label3.text
and so on.
