Sockets - Check That If Another Computer In The Network Send Some String Data To The Listener Computer?
Mar 19, 2012i have a task to create a TCP Server (a program that is listening on its network card interfaces for incoming data stream).I have search on the internet and i found that i can use two methods : Socket or TCPListener class.I have created an example for Socket class, but i wondering how could i test it? I need to check that if another computer in the network send some string data to the listener computer , then this message should be displayed.Here is the example from microsoft that i am using for TCP Server using Socket:
Public Shared Sub Main()
' Data buffer for incoming data.
Dim data = nothingc[code]....
But it does not work because of the PORT setting.If in the TCP Server i have "Dim localEndPoint As New IPEndPoint(ipAddress, 0)" the client crashes, but if i change the port from any (0) to 11000 for example,the client works fine.Do you know why?
Later edit2:Maybe i should have started with this question:Which method is recommended for my scope?asynchronous or synchronous method ?

Sep 18, 2009whenever I install my software on someones computer for the first time, it prompts them to install the .NET framework. When I install software from the internet on my computer, it does not require the .NET framework.
I know this is because the program was written in .NET, but otherwise what language would I write it in and with what software?

VS 2010 : Install A Program On Another Computer Without Internet?
Dec 29, 2010 had 3 courses in computer science 10 years ago and decided to go into economics. After a 6 year and continuing career in economics, I decided to dabble in code to assist my economic career. In this pursuit, I have developed some neat things, but I have a simple problem. I code an application, hit build, hit publish, receive a setup and manifest, then put it on my usb drive. Plug the usb drive into another computer. Drag the setup and manifest to the hard drive, hit the button, a graphic regarding Launching Application comes up, then immediately a window comes up stating:
Cannot Start Application.Cannot download the application. The application is missing required files. Contact application vendor for assistance.
The errors stem from the manifest file. It says downloading the file (file path) Hello.exe.manifest did not succeed. It then follows with 3 lines of filepaths for the Hello.exe.manifest.
I am running VB 2010 express. I made a slot machine game for my mother for her birthday one Computer A. I moved the published files to Computer B as described above to test before giving to my mother. The game isn't too important at this point because I tried to test whether the game itself was the problem or if it was my error in lack of knowledge of how to deploy. As such, I created a program called Hello. In Hello, there is simply a form1 and a button1. When clicked, button1 displays a messagebox with some text. Not a rocket science program.
My intention is simply this:Allow the Hello program to be put on another computer via a USB drive and then installed.The two computers are not networked and let's assume the second computer cannot connect to the internet. When I go to the wizard, I select the location I want to publish to. In this situation, my desktop.Next, I select CD-ROM/DVD-ROM instead of UNC path or website. I don't know what UNC path is. I presume CD-ROM/DVD-ROM would be similar to USB drive in that it is a removal data storage item.I chose that the application will NOT check for updates.Finally, I receive this:The application will be published to:
file:///C:/Users/ComputerA/Desktop/
Where I find the files, put them on the USB drive and try to install on Computer B.Also, for more information, I can use those files on the originating computer and they do SUCCESSFULLY install and I can use the application. I have not figured out why it will not install on another computer.

Jul 1, 2010I'm writing a Silverlight 4 application and would like to check when opening the installed out of browser application, whether there is a valid internet connection (to then download some data from my website).

Check If Connected To Internet + Image Available?
Oct 18, 2010Basically I want to have a picturebox which shows an embedded resource if not connected to the internet, and an online image if connected to the internet.I assume this can be done on the form load event, I just don't know the code for it. Basically this is the logic though:
-If 'http:/[url].... is available (therefore connected to internet)
-Picturebox1.Image = http:[url].....
-Else[code].....
How can I code that properly? Would putting it in the form load event work?

View 9 RepliesCheck Internet / Network Connection ?
Nov 19, 2011This is the work of one responder for the most part, and is not indicative of the quality of most of the posts.But you can judge that for yourself.
If you are writing a program that is used to monitor the status of your network, then this thread may not be of interest.
If you are an application programmer that uses network resources to accomplish your goal, i.e. you are using SMTP, FTP, HTTP, NNTP, NTP etc., and you think that you need to check for a connection first, then read on.Follow up to this.Before getting all geeky let's take a little detour...
Five days a week I get up, eat breakfast, check my email, forums, etc., take a shower, get dressed, and then drive to school.Many of you probably have a similar routine.What is interesting about that is not what we do, but what we dont do,because of our expectations and experience.Here is what I dont do.
I dont stick my finger in the electrical socket to see if there is electricity for the coffee maker and toaster.I dont fire up the command prompt and ping some host on the internet to see if I have connectivity.I dont check the battery, tires, water level, clutch fluid level, washer fluid level, etc.,before I drive off.
All of that is based on expectation and experience.So why would you write an application that pings the internet before it did something (SMTP, FTP, HTTP, NNTP, NTP etc)???? Is your experience or expectation that the network will be down?To illustrate and hopefully convince you that, like Oblio, it is pointless, create a new form with three buttons. In the following examples I use a WebRequest / WebResponse as my 'Something'.Here is what some think is a good approach, the classic ping-then-do, what I think you shouldn't do.[code]....What is wrong with this code is that all of the network IO is being done without a Try / Catch block.
Get An Application To Check Internet Connectivity?
Jan 10, 2012I need my application to check for internet connectivity on my user's computer. If there is, an image is displayed and if there isn't, a different image is displayed. Here's the code I used to get this to work:
Private Sub Window_Loaded(ByVal sender As System.Object, ByVal e As System.Windows.RoutedEventArgs) Handles MyBase.Loaded
If NetworkInformation.NetworkInterface.GetIsNetworkAvailable Then
Dim bi1 As New BitmapImage
[code]....
I decided to test this on my own computer by changing my default gateway (thereby making it seem as if I lost connection). But I realized that the code still showed that I was connected. So I'm thinking that it's only checking for connectivity of the interface - which in this case, is my connection to the router (which is true, I was connected to the router).How do I check that the user's PC is actually connected to the internet? I read the article Check for Internet connectivity but it's in C# and I don't understand that.
