Is it possible to view code of an .EXE file, and can I get audio info from soundcard

[Designer]

Is it possible to look at the code of an .exe file to see how it works

I've got a program for an external system control box that works off the USB port and i'd like to see how the software communicates with the smart-box with the aim of writing my own program.

Also is is possible to pick-up on the beat pulses of music coming into the PC from the line-in on the soundcard, i've seen it done but would'nt have a clue how to do it myself with VB.

Thanks.

You can use debuggers to see the register values and so forth, but that's probably not going to be very helpful. What you want to do is view the source code of the executable, and to do that you would need to decompile it. I don't know of any good decompilers. It is also probably a violation of the software EULA to reverse-engineer it like that anyway.

Problem is, that the software they supplied with the box is'nt really up to scratch and I suppose it might be a violation of the EULA if I decompile it so i'll scrub that idea,

Any idea's how to get a beat pulse from the soundcard line in into VB?, so I can make other software interact with music.
