View 1 RepliesI have built a USB interface card which transmits a binary value to the computer dependant on which inputs are active. For example, if inputs 1 & 2 are on, the output will be 3, likewise if inputs 1 & 3 are on, the output will be 5.My problem comes as I wish to get the binary integer into a format whereby I could have 16 checkboxes (one for each input), and 'check' the ones to which the inputs are on. For example, if inputs 1 & 2 are on, then checkboxes 1 & 2 will be selected, likewise if inputs 1 & 3 are on, then checkboxes 1 & 3 will be selected.The largest binary number that will be going to the computer is 65535.The only way I can think of doing this at present is to do the following a lot of times:

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 have used another program (coded in C++), and I have successfully read the S-port-data - and that's what I mainly need the application for.
Do you guys have an "easy" way to interface with the Parallel Port using VB .Net?I don't want to use C++.
