View 3 RepliesI am trying to convert a mp3 to wav and I need to know...What is the very first thing you see when you open a wave file up? the 2nd, the 3rd, 4th and so on. Is it the riff header or the riff header contents(ID, size, Type). I need this info for a Regex string that would look something like this...
'Frame/MaxFrame (PercentDone%) | CPU time/estim | REAL time/estim | play/CPU | ETA
Private Shared _regLine As Regex = New Regex( _
"(d+)/(d+)D+(d+)D+([d:]+)D+([d:]+)D+([d:]+)D+([d:]+)D+([d.]+)D+([d:]+)"

So, 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)

View 8 RepliesI am trying to figure out the numSamples in this:The canonical WAVE format starts with the RIFF header:

This works fine for getting the wave file info, It just doesn't display the numSamples which I need.
I have used DirectSound to play a wave file in my application using the function CreateSoundBufferFromFile. It works perfectly.Now I want to play files from a resource dll file. I have created 1n2v32.dll file having nearly 100 small wave files named 1,2,3... I can play them using LoadLibraryEx, PlaySound & FreeLibrary.Now, I am trying to use CreateSoundBufferFromResource function from DirectSound api to play these files. I get Run-time error '432': File name or class name not found during Automation operation I used the following code to create the buffer.
Set LDSB = LDS.CreateSoundBufferFromResource(App.Path & "1n2v32.dll", "14", BufferDesc, gw)

View 3 RepliesI have a created a small application that records and plays audio. However, my application needs to save the wave file to the application data directory on the users computer.The mciSendString takes a C style string as a parameter and has to be in 8.3 format. However, my problem is I can't get it to save. And what is strange is sometime it does and sometimes it doesn't. However, most of the time it failes. However, if I save directly to the C drive it works first time everything. I have used 3 different methods that I have coded below. The error number that I get when it fails is 286."The file was not saved. Make sure your system has sufficient disk space or has an intact network connection".[code]
View 1 RepliesI would like to read a WAV file I download in isolatedStorage; actually I use a media Element on my Window which I set the source from the IsolatedStorageFileStream
Dim IsoRead As New IsolatedStorage.IsolatedStorageFileStream(MsgFN, FileMode.Open, Store)

Mainwindow.Playingsound.Play()
Bu it seems not Working, I dont hear anaything in the emulator.
I 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.

View 5 Replies[URL]..I wrote a program with a timer set to tick every 100 ms. The values oscillate between 109 and 110 ms. Each tick, a variable adds +1 to itself; it starts at 0 and goes to 9 and then it goes back to 0 where it continues the addition process. When the timer ticks 110, the variables is added to a textbox. The pattern is something like this, which you can see in the above youtube video. 5 9 5 9 5 9 4 8 4 8 4 8 3 7 3 7 3 7 etc.

how to save information into a text file from runtime VB2005. However, I wish to be able to write the information into any kind of form of file that cannot be simply opened and read by anyone (such as text file can be). Is there anyway that VB2005 can do this?
View 2 RepliesI'm using Visual Basic express 2008.The application I am working on is the first major project I have ever undertook with visual basics. The application is a launcher for a private server for world of warcraft.I have a menu bar that pulls the file path of the wow.exe and puts it in a hidden textbox, I then have another option that saves this text to c:wowexe.txt. All of this works GREAT!
How can I read the .txt file to end and return the information stored in the .txt file to this line of code.
Dim RetVal
RetVal = Shell("This is where I need the data from the .txt file to be seen", 1)
If your wondering why I don't just type in the path of the .exe, it's simple, not everyone installs World of Warcraft on the C drive.
I am writing a program that uses several textboxes that a user will fill in and then click the add button to add the data into the datagrid. There is no backend database or anything. Just seeing the data in the program only.

I've done copying textbox data into txt files but I can't find a method to copy datagrid data into a file.
I am making trying to make a program that can read the file information directly from a specified file, but I am having a lot of difficulty reading things like file comments.An example of this can be found in windows XP when you alternate / right click on any file and click on properties.

1.Can this information even be read in VB.NET
2.If so how
3.If not do I need to create some kind of data file to store the file information

I have a program that speaks wave files. This works problemless with the Soundplayer class with the following code:
Sub MyPlayWav(ByVal WavFileName As String, ByVal StartPos As Long, ByVal EndPos As Long)
Dim wp as new SoundPlayer
wp.SoundLocation = WavFileName
wp.Play
End sub
The soundplayer does however not seem to have a method to play the wave from position StartPos to position EndPos and achieving just that would mean quite a reduction in downloads of these files.
The soundplayer does have a stream object, and that does have a seek method, suggesting that there might be a way to accomplish this, but how?
I plan to include other media files as I am developping the project, and I guess I will be confronted with the same problem.
