I'm realizing a .NET chat application but i still have that error: I can send only a message per connection. For example. With the code below, i can send only one message that can be received correctly by the other peer, but if i send another message message, on the same connection,it won't be received by the remote PC. Here is the code:

i've been wanting to do this for a few years now and it amazes me that no one can come up with a solution.i want to write a program (preferably in vb.net) that can send a message to another computer (or device) that is connected to the same network as me. I want the message to appear on the other computer (or device) in a popup message box. Also, it would be ideal if this could be done through some sort of bluetooth connection, if not then local ip connection will do. I don't know how i would go about doing this but i know it's possible because i've seen some programs do it... in fact i've seen a program called blackrain that without any additional software installed, can display messages on an ipod touch screen to instruct the yser what to do, and then display the results from their input on the computer screen, almost instantly. I would like to know how that works as well if anyone has any thoughts please feel free to share them!

My tcp client has made a connection to the server script! Now that it has connected, how can it send a simple string? I do not know what any of the overloads for the .Client.Send method even mean, or how to use them. I already have a system set up on the server side to parse the string when it is received on the server side, but I have no idea how to send a simple string to it.
View 2 RepliesI am trying to add functionality to an existing program that can send a message from a Windows XP and Windows 7 computer to a group of computers that are running XP and Windows 7. Previously I was doing this with Net Send but as we are no purchasing
Windows 7 machines when we need to replace old computers, that is no longer an option.
I would prefer to have the message appear as a popup on the receiving computers as this is for calling for assistance from a supervisor or the QC department and they will not have to send a response.

A little while back, someone asked the question "How can I send an SMS text message via a VB program?", and it's not the first time that I've seen this asked. I thought, as a little side project (mainly just to get my head away from 'real work' for a while). Of course there are several ways this can be done, including the use of a GSM modem, but this only focuses on one aspect: Sending an SMS message via e-mail.
Rather than clogging this forum with a lot of code and screenshots, I've put it all together on my site.

View 1 RepliesAll,I am trying to implement something so that my VB can be able to send/receive SMS messages to cell phone(modem). I tried researching a bit and found out that we can use MsComm control to do this but it is not available in Visual Basic express 2008 edition. Can we use serial port class to do this? If yes, how could we implement this?

View 1 RepliesNeed some advice on class design. I've just started to use xxxService classes, so not really sure when and how to use them. A number of (identical) client applications connect to this program with socket TcpClient. Different type of messages needs to be sent from several different classes. Should I call a service class, with static methods, whenever I need to send some message (like code below suggests), or should I rather raise an event, and have some class registered to those events, that will format and send the messages.
That would kind of hide that sequence of events from these classes, but on the other hand, it would be a centralized class where one can see easily all events that trigger a message send. Which feels like a benefit. Would like to hear some advice on this. And if my last suggestion makes sense, what could such class be called, and would it be considered a ..Service class?
Example: (code is a bit "rough")
Class UserConnection
tcpClient As TcpClient
Public Sub SendMsg(msg as String)

How would I create a multi-tcp chat room. Im having trouble handling them. I know you can store the connections as arrays or store then in hash tables. Is there a better way to data to a specific connected client. My way was to just broadcast the message to all the connected with the clients name (EX: Client1||MessageHere) || is the split. The client reads the message and sees if client name matches if it does then it will display it other then that it will not. I found out that my server was sending out useless data with this method. So is there a better way to handle/Send messages to a specific client?
View 2 RepliesI'd like to create one as I am an affiliate marketer who wants to reach customers based on key words. I don't regard this as spamming since I'm not randomly sending out links its based on key words like I said. Y!A might regard this as spamming anyways but so what. In Yahoo Answers you click the question you want to answer, type in the answer, it takes you to a preview screen, and then you click submit. I suppose the script/program could involve automating this task.
Its not that I need everything to be done when I'm away from the computer, I don't mind working the program at all each time I send a mass amount of messages. Someone created a program a while back that was *supposed* to send bulk messages as they stated in the description but as it turned out this was not an option you could only comment on resolved questions. When I did send mass comments to questions which related to my key words, I clicked the link to confirm my comments went through and they did not! This program was a waste of my time and energy but that's life.

I have a .Net program that has to run on a cluster of server 2008. To find out the right IP I resolve the dns by GetHostEntry(VarDefinedInfConfig).AddressList(0)
but when I am converting my old code (this code picks the wrong IP) dns.GetHostName().AddressList(0) => this returns a virtual IP and not the right one.So I changed my TcpListener to (dns is parameter from config)Dim listener As TcpListener = New TcpListener(New IPEndPoint(Net.Dns.GetHostEntry(dns).AddressList(0), 8001))
listener.Start()

View 2 RepliesI am a Network Administrator in the Army so programming is not my strong area. I have been messing with Batch files and WMI, just recently i started VB Scripts (VERY BASIC) like adding an input box to set computer name, scan network for computer name on domain, return wmi info for that remote computer etc... I know there are programs out there that can do all of this, however the Army will only allow certain approved programs to be installed on government workstations, i have been using .Bat files to gather info which is fine, however it is very time consuming when you have entire subnets with computers, networked printers, etc to place into a spreadhseet for higher headquarters tracking not to mention the over 20 columns of required data to track for each computer. I have VB 2010 Express, working on a Windows Form Application Project. Goal is to interface my VB Script (written with notepad) with a GUI that will generate an internal spreadsheet on the form window in a datagridview. So far i have the basic window and i have my gridview with my column headers set. How do i get the data into the columns and rows accordingly.
Application Basic: Execute Program, in main window select button (Scan IP Range) <--- I want this to open an input box for the beginning subnet, input base address to start scan from, next input box for end range, then msgbox for start scan. i want the results of the scan to autofill the datagridview and add new row for each IP address that had a ping reply, returning valid data from WMI results as it receives the data. What would be the best method to achieve my goal. i am not asking you to write the program, i have been looking and studying MULTIPLE sites, think i just need another set of eyes on this to unlock the knowledge i have locked away, if ya know what i mean. Also, if you don't mind let me know what you think of this app im trying to turn out... Super Thanks for your help.This is the Base Batch File running. It calls an external VB Script written in notepad. (I want this implemented into the app form so there is no console window.)This is the inputbox from external VB Script that is called.This the result of the external VB Script (the info i want to put in the datagridview of the app.)I also, for some reason can't get scroll bars to show in the app when i hit F5, theres about 15 columns passed the MAC column...?
Am working a vb.net 2008 project using ms access database 2007 and i successfuly finished it. i published the project and burnt it with cd. my database path in vb.net was located c:Deploydatabase.accdb.
so i installed the program in to another 2 networking PCs. when i run them and put the database path c:Deploydatabase.accdb in every computer, its working. but the problem is that:
i need the database to be accessed by server or my machine for instance where every other networking computers are able to access my database in this location of my machine (my be as defualt) without not putting it to their pcs.
This enables me to see what every machines users can add information to the program.
for example, i have got 10 computers networked each other (i.e comp1, comp2, comp3, comp4, comp5, comp6, comp7, comp8, comp9, comp10). i have installed the program in every computers so when/if comp1 adds/edits informations to the program, then all other computers are capable of receiving this information which means comp4 can see what comp1 has entered in the program.
