Jan 27, 2011I have a simple tcpclient/server messenger running. Everything works great, except for when a client exits the software. When someone exits, is crashes the server with various exceptions and the server has to be restarted, as well as the clients. What I am looking for is a way to properly "log out" a client BUT leave any other connected client on so that is no break in the chat. Then the person that logged out or a new person can join back in whenever they choose.

VS 2008 Create A Client / Server Chatroom Using TCPClient In Visual Basic
Jan 6, 2010However I have hit a massive brick wall with my program. My program that I'm trying (can't emphasis this word the importance of that word) to create a Client/Server chatroom using TCPClient in Visual Basic. So far I can get my client to speak to my server. However, i'm trying to get the returned data to display in a listbox which never happened, i then tried a label, which again never happened then a text box which I'm sure you can figure out how that went! I'm not great at networking programmers nor am I not bad I'm terrible but duty calls when it comes to projects.
The code I currently have was mostly taken from the net but when I have the program fully work and I understand how the software works I intend to heavily modify for it to suit the needs of what I need to achieve. where I can get my client to display the data from the server that I have already sent to the server (which displays successfully within the server).

Creating A Sales Tax Program In Visual Basics?
Nov 13, 2011Assume a grocery store approached you to write a simple program that calculates total sales of purchases. The program should accept item costs as input, calculate the tax on each item (8%), then display the item cost, total cost, and total after taxes. Item costs will be added to a listbox while the total without the taxes will be displayed in a label, the tax amount in another label, and finally, the total cost (items cost + tax) in a third label. this is the problem I have to program for,

VS 2008 : Creating Own DataReader Like TCP Client/Server?
Jun 2, 2010I'm not even sure where to start. I would like to create something like the ADO DataReader but that works in a TCP Client/Server scenario.Basically, in the TCP Client, I want to be able to call a certain command in the TCP Server which will return a DataReader like object, which I can then iterate through such as:
while dr.Read from the client. In each loop, I would parse out the various fields as in a normal DataReader.The reason I want to do this is to gain the inherent efficiency of the DataReader object since it doesn't first load ALL of the data. To my understanding, the typical TCP Client/Server setup using streams, would first load all of the data on the server, then transport ALL of that data to the client for processing. I want to avoid that, and just stream the data as the client requests through the Read() command which means the connection will remain open to the server while the Read() command is being issued by the client, or until explicitly closed by the client.

Feb 2, 2009I am trying to learn how to use the tcplistener and tcpclient classes. While I am attempting to compare something that is sent from the client to the server it seems that it adds a bunch of spaces, the reason I know that is if I write to the console what was sent it adds a bunch of spaces at the end. Is there anyway to get rid of it and just get the original text. I tried trim() but that didn't seem to work but I could have been using it improperly.

Jan 4, 2009I am trying to do a very simple demo - load data from an access database and let the user manipulate it with a DataGridView. Here's what I understand so far:1) Create an OleDbDataAdapter by passing it a query and a connection.2) Create a DataSet by calling .Fill() on the DataAdapter with a DataSet object and a name for the retrieved data.3) Attach the DataGridView to the DataSet using the .DataSource property of the DataGridView and the .Tables property of the DataSet.However, I was told there is a much easier way to do it now in vb2008 using TableAdapters.1) Create a DataTableAdapter ( I can't actually find this object -what is it called?)2) Use the Fill method on the DataTableAdapter to connect it to a DataSet3) Now anything the user does in the DataGridView can be saved simply by using TableAdapter.Update.
