how can I determine if there is network traffic?I would like for example to show how fast the network traffic goes or to add a flash using a picturebox to animate the network activity
View 5 RepliesI want to create a Small application for all the computers in my house that Monitors Network Traffic Because we are using large amounts of data each month and that leads to high costs.I can Monitor A computers total traffic with the system.net.networkinterface namespace. Now I would like to know if it is possible to Monitor an Process/applications Network Traffic to pinpoint The Problem.I've Read About WMI But there is so Much info on MSDN that i can't actually get to what i want and i don't think there is something so direct like the amount of bytes sent over the network.
View 3 RepliesI am trying to write a program that captures log information from my Cisco 5510 firewall. I have a service working where it will perodically write text to a file. What I need now though is how to capture the actual traffic coming from the firewall on the network. It uses UDP port 514 to send it. I need to know how can vb capture that traffic and write it to the log file. I am a beginner to vb.net so please be patient with me if it seems like I am asking too many simple questions.

View 2 RepliesI have an application that automatically updates addins for excel from the server to all the computers on our network. right now all i get is an error if excel is open, but what I want to be able to do is check if excel is open on each computer first and give the user a chance to save their current work then close excel. otherwise i cannot update their addins if excel is open.

What I want to do is see if a folder on the network can be opened successfully. I do not want to ping it, but actually open it and see if it loads. I can do this for a website by retrieving the http status code, but I can't find any references to something similar for explorer.exe. Here is a basic flowchart of this part of the program:
ping server --yes--> access \server_namefolder
--no--> access \server_IPfolder
--no--> Authentication Issue
--yes--> DNS Issue
Note also that just checking authentication won't work because it could also be a DNS problem. I guess I could check them both, but I would rather do it this way if possible (and I don't know how to go about checking either one)
Does anyone know if there is a way to determine if a drive is local or a network drive?

View 6 RepliesHere is my idea so far: I have a bunch of computers connected in a local network. One of them is a MySQL server, one will have a vb.NET program wich will act as a "second server" and the rest will be different clients. What I want to do is that the "second server" will send out some kind of message or network package to some of the clients in the network, and they will execute a code based on what message it is, or what kind of package it is. I'll give you a simple example:

View 5 RepliesSimulate a traffic light with three small square text boxes on the form. Initially the bottom text box is green, the rest are dark gray. When the tab key is pressed, the middle box turns yellow and the bottom box turns dark gray. The next time the tab is pressed, the top box turns red and the middle box turns dark gray. Subsequent pressing of the tab key cycles through the three colors. Hint: First place the bottom text box on the form, then the middle, then the top. I did all this and dabbled below. Does that look at all correct...minus the timer thing...I got the timer code (which is not needed) but am not sure how to write it so the tab key does the work. This is really confusing to me, but it is a required class.
Dim Counter As Single
Private Sub Timer1_Timer()
Counter = Counter + 1

Simulate a traffic light with three text boxes placed vertically on a form. initially, the bottom text box is solid green and the other text boxes are dark grey. when the tab key is pressed, the middle text box turns yellow and bottem box turns dark grey. next time the tab key is pressed, the top box turns red and the bottem two turn dark grey. Basically the tab key cycles through the colors.First off let me say im not looking for an entire code. What im looking new to VB (been working on it for only a week) and im haven trouble finding a sourcecode for "tab". I named the bottem text box "Green", middle text box "yellow" and top "Red"....how do i go about finishing the code?

How can I monitor the internet traffic and identify when a specific website is visited so that a certain function could be run? I'm making a internet censor program for a school project.
For example, I want to be able to browse the internet all day long with the program running in the background, but once I were to visit a specific URL (listed in the code somewhere) the program would run a function when the specific URL is detected.
so with google analytics , it can tell you if you have direct traffic or if you traffic was referred from a website. I have no idea how it can tell that the traffic has been referred, and I want to fool it to make it look like I was refrerred from another site using the webbrowser component.

View 1 RepliesI want to make a Small Traffic Monitoring Program for our house. Since in South Africa Internet is One of the many things that are way overpriced I want to monitor each computers traffic with a small Program since even when we are not at home for a day we might easily use 2 gigs of data. Somewhere a computer is downloading like mad?For a 4 mib(you only get 3.5 at most) line here Will cost you around R413(36 GBP/ 58 Usd) per month and One gig of data around R19(1.68 GBP/ 2.70 Usd) - R112(9.9 GBP - 15 USD).Ok enough Complaining. Each Computer in our house Connects to the internet either with lan or Wlan So is their a way to get how much traffic passes through one of those OR is there a way to monitor the total internet traffic regardless of how it connects to the internet ?

View 3 RepliesMe and a few other people are developing a piece of software that measures levels of distraction based on some user settings. The user will be able to designate certain programs, websites, etc. as "on task" and anything else will be considered "off task" by the program. The only road block we have run into is being able to grab the user's current web page in real time -- at any given second we need to be able to programatically determine what web page the user is viewing (in any browser) and determine whether it falls under "on task" or "off task". We would like to do this by creating a C# extension for Fiddler2 but are open to other suggestions as well (the software itself is programmed in VB.NET).

View 3 RepliesI am wanting to create an application that will monitor the upload/download traffic of a user. Can someone point me too some code that I can have a look at?I have found SharpPcap - A Packet Capture Framework for .NET, but cannot find any vb.net code for it.
I have found this code:
Dim Properties As IPGlobalProperties
Dim StatV4 As IPGlobalStatistics
Properties = IPGlobalProperties.GetIPGlobalProperties
StatV4 = Properties.GetIPv4GlobalStatistics
Dim Packets As Long = StatV4.ReceivedPackets
What actually is a 'packet'? Can I calculate the download/upload from this code by maybe multiplying the recievedPackets by packet size... or something like that?
I have a .NET 2.0 *.dll that calls My.Computer.Network.Ping(). The *.dll is then run out of an *.exe via AppDomain.CreateDomain() and Invoke(). The problem is that this works just fine under Windows XP but under Windows 7, I get an exception saying that no network connection is available. I tried the Ping() call out of a small console application under Windows 7 and it works just fine.

View 1 RepliesI am writing some code as part of a framework for opening a file.The file is of custom type and should not be opened by more than one instance of my application. To stop multiple file opening I use a filestream to create a lock file and then keep said filestream open. This seems to work in preventing another instance of my application from opening the file ( as it will fail in recreating the lock stream in the files open code ) but if the file is on a network share and the network drops then the original application also can not access the file any more.The code to get the lock stream is as follows:
Try
' We need to keep this stream alive to prevent other applications gaining access to the lock
mLockStream = New FileStream(mLockPath, FileMode.CreateNew, FileAccess.Write, FileShare.None)[code]....
In this I create the lock stream the first time round and then if another application tries to create it, it throws an exception and stops them from getting any further. This is kind of how it needs to work, unfortunately as I said, if this is done across a network and then the network connection is dropped for some reason then I can not delete the lock stream as I get an IOException telling me a process cannot access the file as it is open in another process ( which shouldn't be happening I don't think).
