C# - Limit Wifi Access Using .net Application?
Aug 30, 2009
Currently following is the setup of my wifi connection.
Laptop 1 ------> Wifi Router <------
Laptop 2
There are about 5 laptops which connect to the wifi router to access internet. Network is password protected so anyone with a valid network key can connect and access internet.
I am planning to develop a local website which will be having a list of username and passwords. I will also remove the password of the wifi network so that anyone can connect.
If a connected system tries to access a web page in the internet then redirect them to a Login page (in the local website) and ask them to login. Once successfully logged i,n the mac id should be added to "Allow" list and monitoring starts. Internet should not be available for those who don't have a valid username and password.
I was thinking about developing the application to block/allow internet access though a vb.net/c# application.
I am okay with the website part. What I would like to know is
How I can block/allow internet access through the .net application. Is it possible in .net or should I be going for an unmanaged code development? If it is possible where is the best place to start? I have experience in winforms development but not much of network programming. Will there be any change in my current wifi setup? May be a new webserver/proxy server which will host the website and the windows application?

I was wondering if it's possible to access information from within Visual Basic about WIFI connections, such as their SSID, MAC address, ect. I don't know whether I have to add a reference, what commands to use, ect.

Is there a way to list up all connected pc to my router (wifi )? Even if they arent on same LAN (like ipod touch). Or list list all user that are using internet? Atm I figured out this code :
Public Class Form1
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
WebBrowser1.Navigate("http://192.168.15.x/DHCP_Static.asp")[code]....
Which i though was suppose to list connected client but logged on my DS and didnt listed it up. Maybe it doesnt list DS?

I am working on a little project for my phone creating some sort of remote to turn up/down my system volume via wifi. The phone will send data to a text field on the website lets say such as "vol up" and the vb app sitting on the computer will be constantly reading this text field for key words like "vol up", "vol down". when it see's a recognized command it reacts by turning the volume up and so on. And one more thing: Is it possible to have a vb app that uses http? E.g., sits on port 80 itself and can be accessed via local ip.

I'm using VS 2010, and I did a project using VB and a database in Access. The problem is that when I try to put that "application" on other computers, sometimes, is not working. I thought it can be because on these computers they don't have access, but on one computer, is running another app which is using Access and there is no Access installed. How can I check if my application requires Access to be installed or not?
Here is a example of how I did the connection:
Public AccessOLEDBConnString= "Provider=Microsoft.Jet.OLEDB.4.0; Data Source=" & myfullpath & ";Jet OLEDB:Database Password=password"
Function getConnection() As OleDb.OleDbConnection
[CODE]...
And when I want to have access at the data I'm doing like this:
dim conn as Oledb.OledbConnection
dim sql as string
dim ds as Dataset
[CODE]...

My boss gave me an MS Access application that was developed by our former colleague. He wants me to convert that application to VB.Net Windows form application. I went through the MS Access Application. It contains tables, queries, forms, reports and macros. I could not find the programming (Where is the code written in MS Access?). My boss wants the windows application to be same as the MS Access Application (both in design and logic). I don't how will i develop the windows form. How can I achieve this?

Is it possible to capture the raw signal from a WiFi card in the same way you can capture the signal from a sound card? (I already found code for working with a sound card and for drawing spectrograms) I'm wondering because it would make a cool radio-type project. I'd prefer a solution that integerates well with .net (VB or C#).My basic goal is to capture the ambient radio waves and build a primative "telescope" of sorts. Using the built in computer hardware is just the easiest way to accomplish this. If you have any other suggestions about how to accomplish this goal in a different way please post it as an answer also.

I need to be able to interact with an application's GUI within another application. Basically, I would like to run an application and have it's GUI appear in a MDI-style Form in my application. Is such a thing possible? The reason I need to do this is because I need to access an application remotely without having to use Remote Desktop or similar tool. Any questions on this, feel free to post.

I've trying to access an appsettings key value in my vb.net 2.0 web application.I've put the key in the app.config file:
<appSettings>
<add key="DownloadURL" value="http://<myURL>/" />
</appSettings>
I've followed the instructions here, and it says that I need to access this key like so:
URL = System.Configuration.ConfigurationSettings.AppSettings("DownloadURL")
But I get the following message:
Public Shared Readonly property
AppSettings() As
'System.Collections.Specialized.NameValueCollection'
[code]....
I tried to replace the old method with the new one, but it does not exist.Strange, since I've done a similar thing with a web app and it did exist there.
