Wave File Won't Play?
Oct 4, 2008So, I re did my project in VB.NEt instead of C#. So, I put all the sound files in the resource files. I made a routine to play the sound file but it says that to make sure the sound file exists. Which it does because it played in the resource manager.Here's the sub routine to play the sound:
Dim sndplayer As New Media.SoundPlayer
Public Sub TestSound(ByVal snd As String)
My.Computer.Audio.Play(snd)

Apr 4, 2009In my project,I used the wizard in VB.NET2008 Express to connect to my database. I have a data connector, adapter, and dataset controls on my form.

I now want to save the updated dataset to the database. I have tried using the adapterCustomers.Update(datCustomers) command to no avail. how to save the dataset to the database?
Retrieve Information From A Binary File, Alter That Information, And Put It Back Into A New File?
Aug 27, 2009I am using VB2005 and trying to put an application together.What it needs to do is retrieve information from a binary file, possibly alter that information, and put it back into a new file.The file is a .wav file with data appened to the end. There is an additional section at the end of the .wav file which stores xml data.I have found that if I open this in a hex editor and make a 1:1 swap on any of the bytes that the application that the file is for can still read the XML.If I tried to add or remove characters from the XML then it would not read. I located a header byte and incremented it to resolve this.
This worked as an excellent bandage to do conversions where the data always needed to be changed to the same thing.What I have been asked to do is build logic that allows for different things to happen depending upon what data is contained within the file.The method that I am currently trying to impliment is:
Read through the file with a system.io.binaryreader
Searche for a bytestream that will signal data is coming
For example:
If System.IO.File.Exists("C: est estread.wav") Then
Dim findit() As Integer = New Integer() {&H3C, &H55, &H73, &H72, &H44, &H65, &H66, &H30, &H31, &H30}
Dim i As Integer[code].....
And then extract all the data till the end of element marker "<" It seemed like there should be a better way and I was looking for some insight. If I proceed with this method, I will have to read the file one time to gather the information and then a second time to write it all out with the header modified for length.This is my first experiene with working with binary files in this way.Also,I've been experiementing with building a string and slapping it back in at the end using the binarywriter.write(string) method.I noticed that it was putting in header characters before the string.These seem to change if I change the length of the string.At one point it was d0 07. Later it became e7 07. Does anyone know of a way to prevent this header from being inserted?
I tried a for each loop to grab all of the characters from the string, convert them to a byte array and deposit the byte array into the file, but the header remained the same. When I write the byte array generated from a system.io.binaryreader I do not get this header.
Play A Simple Note Passing It The Frequency, Stereo Position, And Duration?
Aug 19, 2009In VB.NET 2005. i am trying to experiment with sound. I started out trying to produce a single note at a single left-right position, for a particular duration (maybe until i shut it off. with a particular frequency.It can be a sine wave, or a square wave or maybe a general midi sound. This seems to me to be a simple task, but i cannot find out how to do this.I suspect that the answer lies inside direct sound or xaudio2. I want a simple solution i don't want to have to spend 1600 hours learning xaudio2 in order to learn how to how to make a beep.The ideal answer wold be for me to write a routine that accepts waveshape,freq,volume,Stereo_Position,duration).

Aug 21, 2011I have no programming experience at all, although did learn basic at school 30 years ago how it's changed Anyway I am trying to write the simplest program that will play a song for 1 second.The reason is that me and my friends are Jam fans and we want a contest to see who can name the song with just a second of it playing (at any part in the song).
I have managed to to get the song to load and play but I only want it to play for 1 second before it stops.I can do the rest of the coding from there but I just can't get it to play for 1 second. I have a form with a button to start it off and this is all i have so far

Read Text File / Search For String Then Add To Line And Write Back?
Nov 18, 2010I would like to read an HTML file, search each line to see if it starts with </head>. Then add the centering code after it. That line at destination file should read:
</head><table border="0" cellpadding="0" cellspacing="2" width="760"align="center"><tr><td>
After this I don't care to search for anything. Just read from source and write to destination. I know there are programs out there to find/replace text in series of files but I am not allowed to use external programs.

View 1 RepliesMake 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
