View 1 RepliesWrite A Program That Validates An Inputted Ten Digit ISBN Number Using The Check-digit?
Sep 16, 2011I'm supposed to write a program that validates an inputted ten digit ISBN number using the check-digit at the end to ensure that the sum is a multiple of eleven. Before calculating this and detecting if the entered number is indeed a valid ISBN, we're required to check the first nine digits and see if they are indeed integers. After this the tenth digit is checked to see if it is "X" (for ten) or 0-9.
With the code I've written it keeps returning false for whether or not the ISBN is valid, even with valid numbers. I feel like its something to do with the hyphens; have I misused the replace function?I'm a little lost on how to make my code work, but I'm fairly certain my logic is okay so far.

Record Sound From Microphone?
Aug 19, 2007I am looking into recording sound from a microphone using vb.net into a wav or mp3 file. I've Googled loads but only found 3rd party controls and C# code, which looks too sticky to convert..[url]...
I found this article on the code project which uses WaveIn and WaveOut but this looks unconvertible.... and I would like to avoid using DirectX SDK because the installation files are large and I wouldn't like users to have to do that.

Sep 12, 2009get data like the pitch and volume of the sound currently being "heard" through a microphone?
Do you know the little graph which the Windows 98/XP sound recorder used to show? It used to show the pitch and volume of the sound which was being recorded. Like I want to get the data from that.
Basically, I will start experimenting this stuff by showing the volume of the sound entering the microphone in a label. And maybe the pitch too.

Make Program That Counts The Frequency Of Each Letter In The Alphabet?
Feb 22, 2012I'm trying to make this program that counts the frequency of each letter in the alphabet for a set of ciphertext, the calculation i want to do is:lettersum*(lettersum - 1) + lettersum*(lettersum - 1) for however many letters example: User puts aabbcc in the ciphertext box , the output should be
2(2-1)+2(2-1)+2(2-1) =6 If the user inputs aaaaab the output should be 5(5-1)+1(1-1) = 20 The code I have so far only counts the last number of letters for example: aabbcc only reads the cc part and only outputs 2(2-1) = 2 instead of 2(2-1) + 2(2-1) + 2(2-1) = 6.The code below is part of a button_Click item

C# - Make A Program That Detects The Note That Is Being Played In Front Of The Microphone?
Nov 21, 2010I want to make a program that detects the note that is being played in front of the microphone. I am testing the FFT function of Naudio, but with the tests that I did in audacity it seems that FFT does not detect the pitch correctly. I played an C5, but the highest pick was at E7.I changed the first dropdown box in the frequency analysis window to "enchanced autocorrelation" and after that the highest pick was at C5.

Mar 31, 2010ok i am making a "game" in visual basic 2008 and I have come across a problem...
I need it to be able to play a sound without saying that the sound is stored at "c: estsound.wav"
I have it working and playing the sound when i want but it only works on my computer
How can i save it into the resources just like you save a picture into resources?
Btw if it helps i am playing the sound using the axwindowsmediaplayer thing and it just plays the sound when the program loads...
so form1load then it plays the sound.
how i can make it play the sound on other computers?

View 2 RepliesSound From An Array Of Data In Program?
Jun 18, 2010I'm getting data from an external source, storing it in a single array, and I want to turn it into sound, even though it isn't really sound to start with. I don't know how to build sound from data arrays, but I think it shouldn't be that hard. I am hoping someone can show me the secret.
The data get's read from a 12-bit data acquisition card at fifty mega-samples per second, and it normally contains ten distinct frequencies from about one megahertz to about five megahertz with some overtones. So it's very high-frequency stuff to start with, but it should be possible to to scale it down by, say a factor of a thousand (where humans can hear) then put it through a sound generator through VB, so I can hear it. Also, I don't want to export it as a .wav file first. I just want to format it and package it for the sound player, so I can listen to it live, as I play with the external stuff that affects the sampled waveform going into the card.
So, maybe I'd take a sample of a fraction of a millisecond, scale to a sound format, then output it to my speakers. A frame of 32,000 samples, for example is about 0.64 milliseconds of real time, but I could scale that out into quite a long sound. Ya think?
