Chat System With One Or Two Ways?
Jan 15, 2010
I'm trying con build a simple chat client/software (whole in on executable) wich start listen from the start on the port 5900 and when a client connect to that port the chat is established.
The problem is that only the client can chat to the server, the server cannot answer the client because the connection is working in one way.The i've tried to connect from "server" to the client when it establishes a connection but the system crash warning me that the port is already on use.

I want to create a tcp/ip chat system using vb.net. I have created using vb6 using winsocks but unfortunately I couldnt find it in VB 2005. I have discussed with some friends about it and they also couldnt do it. I like to try something I dont know in this way I learn more. I want to create the in such a way that the client and server both have an interface and the client and server both have port text-boxes and the client has the host text box and the connect button.

I wrote a server for a tcp/ip chat program using the system.net.sockets class. When I run the program and the client tries to connect to it, there's an error and it won't work. I am positive that the issue isn't with the client, as I have made a connection with the client before.
Imports System.Net
Imports System.Net.Sockets
Imports System.IO
Public Class Form1
Dim server As New TcpListener(IPAddress.Any, 60)
Dim client As New TcpClient

I developed a chat application with an attendant chat server. Everything is working fine. The issue now is the fact that whenever the chat server goes down (for instance, the server system shuts down as a result of power failure or some other problem), by the time the server system come back on, the chat server would have to be restarted manually.
I believe (and I know) it is more appropriate for the chat server application to restart itself when the computer comes back on (and of course regardless of who is logged in and of course, even before anyone logs in). I have a batch file that executes the chat server. My attempt was to create a windows service that start automatically and runs this batch file using a Network Service account on the server system. Although, I'm having a hard time with this (temporarily), I would love to ask if there are any alternatives to using a windows service.

So, in another related post, i got the chat to send to a java server, cool.Now, it's a matter of sending it back to VB.on the server side of things, (in java), I am using the following
JAVA
public static void sendback(String what2send) throws IOException {
ObjectOutputStream oos = new ObjectOutputStream(mySocket.getOutputStream());

I have this code List<string> myList = new List<string>();
myList.AddRange(new MyClass1().Load());
myList.AddRange(new MyClass2().Load());
myList.AddRange(new MyClass3().Load());
myList.DoSomethingWithValues();
What's the best way of running an arbitrary number of Load() methods asynchronously and then ensuring DoSomethingWithValues() runs when all asynchronous threads have completed (of course without incrementing a variable every time a callback happens and waiting for == 3)

I'm new to VB and have over the last week or two been looking at the different ways to play audio (mp3's). Windows Media Player, Microsoft Multimedia Control, Bass.dll, SndPlaySound, MCI SendString and DirectX (including audiovideoplayback, direct3d and directsound.) I originally decided to use windows mediaplayer, mainly because it seemed the logical choice but quickly found out I couldn't get it to work properly.
So I installed the Directx SDK but now I'm completely overwhelmed about what to use and why. I need to be able run the compiled code on a win 2k box, play an mp3 from start to finish then load and play another mp3 from start to finish and so on. Whats the difference between the varied choices and which would be the best for me to use?

I'm looking at creating an mp3 player to keep myself busy. However I'm trying everything I can to avoid using the windows media player COM component. It makes it a little too easyWhile looking around I stumbled upon the DirectX.AudioVideoPlayback namespace and I was wondering if this would be sufficient. Would I be able to create an equalizer and other more advanced things for my application?

I am trying to create a bunch of records, there will be a limited number of "Codes", about 50. Each "Code" is associated with a name from a textbox, I was trying to have it save each one when you click a button, to a .txt file.So, from the start the record will be blank, the person will go through the form, choose a number from a numerical up and down box, pick a name associated with it (both of these are mandatory and not implied). When they click the button, it will save the contents I talked about into a .txt file, say the number is #2, and the name is "Bob", the next time they try to change that value for #2, it will overwrite "Bob".

Im using VB in VS 2005.I have found several methods of testing if a value from a dataset is null. Are there differences between these two ways of doing it:

Is one faster than the other? From some searching online, there seems to be debate about the best way to handle null values.

I have come up with this 2 methods of reading all records on a database table. Both work nice but I would like your expert opinion on which delivers best performance and why.We are reading table "DATA" and filling an array called lstData with the contents of the "Data" field.
1) Method one is using the bindingsourse to go through all the records.
[code]...
My guess is that the first method, while simpler to the eye could use more overhead. What I really would like to know is if the second method really delivers better performance and if it is worth doing all the manual SQL queries.

I have a general question on app.config, or the best way to NOT hard code a SmtpServer.Host = XXXXXXXX setting. I wrote this very simple SMTP texting application and wanted to have the settings not hard code but a form that read or writes to app.config or .ini or registry. my question is the pros and cons? and if anyone hae suggested or a link to sample project that is doing what I'm after. I have a single .exe and am new to vb.net and either want the exe to check for app.config, ini or registry if does not exist to create and then save added config, if the exe runs again it uses the newly created settings.

I've been going through a VB book I had while in College, and was trying to figure out different ways of making programs work.One assignment was to create a multi-dimensional array to figure out wind chill factors. The only part I really can't get to work right is using 2 numericUpDown controls. Using 2 dropdown menus was obviously easy because the items are indexed, but as far as I know, numericUpDown controls are not indexed.
Instead I used 2 selectCase statements to determine the index in each updown control, then passed the indexes to a function to determine the answer.The numericUpDown controls both increment by 5, (wind from 5 to 30) (temp from -20 to 15)Just looking to see if someone has any ideas of a better way of doing this.

I am looking to get some information on updating my own applications. Because what I have to do at the moment is replace the files every time it changes so I would like to know what are the options available starting with the easier ones or does it involve any third party applications. For example I have noticed some applications checks the files before it starts up and then asks a user if he wants to update it

(I'm using 2010 express), which includes, i think, very basic knowledge of coding. I have made a game in vb 2008 express before and it was a basic arcade game where you move your guy from the left to the right collecting points and dodging enemies that are randomly moving in the opposite direction that you are. Now I am attempting to make a sort-of user interface similar to that of the ps3 home screen, as a windows shell replacement app..
so far i have got what I am looking for in terms of moving between the menus, however the code that I have made seems very extensive for such a thing (in my opinion)..the question I am asking is whether there are ways of shortening the amount of code used, or changing it to be more efficient..if someone is willing to help, I will post my code, or upload my project (if given instructions on how to do so)
