Sep 22, 2010I have looked absolutely everywhere for documentation on wifi adapter usage programmatically in any

Capture Raw Signal From WiFi Card As Would A Sound Card
May 9, 2012Is 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.

C# - Limit Wifi Access Using .net Application?
Aug 30, 2009Currently 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?

Dec 2, 2009I have some problems that about GraphicsPath:
How to measure a path's length?
How to insert a point along the path without changing its pattern?
and how to get a nearest point along the path with a given point?
or
get a on-path-point with a given percentage of the length of the path,
e.g.: 3/4 of Path(new point(){(0,0),(2,4)}) = (1.5,3)
(like Adobe Flash, the object can follow a path to move.)
I have tried to measure length with Graphicspath.flatten, but it takes time and not accurate enough. Is there a formula to do that?

How To Measure Time Spans Accurately
Aug 9, 2011I have a VB.NET application that executes a test when the user clicks a "Start" button. The application communicates back and forth with a USB device and eventually stops when the USB device sends back a specific trigger, or if the user chooses to cancel the test. I would like to measure the time elapsed during each test and display it to the screen.The program is significantly complex and I have several timers that control sampling rate, the frequency of the output, the frequency of signals in a calibration method, etc.I tried two approaches so far, both of which led to invalid time measurements. I say they're invalid because I used several stopwatches I know to be accurate in addition to the system clock (the clock with a second hand that pops up when you double click the time in the bottom right hand corner of Windows XP) to measure the actual time of each test. Consistently, my program will indicate more time has passed than actually has.I tried simply dividing the number of samples I took by the the sampling frequency. I got back a time that was about 1.33 times greater than the actual time. This ratio would change with different frequencies, and even with the same frequency from day to day.
I tried using the DateTimePicker in my main form to measure the time passage. At the start of the test I'd record the start time, startTime = DateAndTimePicker1.value, at the end of the test I'd record the end time, endTime = DateAndTimePicker1.value, and then I'd set the text of a label equal to their difference, TestDurationLabel.text = (endTime - startTime).ToString. I initialized startTime and endTime as Dates. I get back a time that is about 1.2 times greater than the actual time.

Oct 28, 2009I 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.
