I am trying to figure out the numSamples in this:The canonical WAVE format starts with the RIFF header:
0 4 ChunkID Contains the letters "RIFF" in ASCII form
(0x52494646 big-endian form).
4 4 ChunkSize 36 + SubChunk2Size, or more precisely:

This works fine for getting the wave file info, It just doesn't display the numSamples which I need.
I 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:]+)"

how to get the wave file information in vb.net like frequency,no of channels etc from wave file
View 3 RepliesSo, 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 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]

I have searched a lot on the web about changing file attributes in .net , it takes me a long time to get the final code but it was really good. But after all of my search I didn't know why we use "And" when we compare file attribute like this:
If (System.IO.File.GetAttributes(FilePath_txt.Text) And System.IO.FileAttributes.Hidden) = System.IO.FileAttributes.Hidden Then
MsgBox("File is hidden")
Else
MsgBox("File isn't hidden")
End If
Otherwise when I want to set Multiple attributes for on file I have to use "Or" with it like this
System.IO.File.SetAttributes(FilePath_txt.Text, IO.FileAttributes.System Or IO.FileAttributes.Hidden Or IO.FileAttributes.ReadOnly)I know this isn't a big problem but , I can't write a code I don't know how it is actually works.
I know how to set an attribute and set multiple attributes but how would I add a attribute to the existing attributes...

In this 2nd one attributes are being changed, but they're the wrong ones and I can't pinpoint it right off hand.
Edit: What the overall goal of this is that if the user has the attribute checkbox checked then the file needs to have it set, other wise the attribute (if it's present) needs to be unset.
I am trying to read all the attributes, there are 3, from a single node. This is what I tried from an example I found:
Code:
Dim xl As New XmlDocument
xl.Load(XMLfile)
Dim rn As XmlNode = xl.SelectSingleNode("p1")
[code]....
I have used a messagebox to show the xl.OuterXml, I see the file is loaded.
So I have been searching around the next and keep finding solutions that all have errors due to upgrades. Basically what I want to do is load the following type of XML file when a button is pushed:

<DATA version="1.0" xsi:schemaLocation="[URL]" xmlns="[URL]" xmlns:xsi="[URL]">
<NOTES> <NOTE NameId="Name1" Colour="13" PNotes="Test7" />
[Code] .....
But after that I want to sort out the attributes. I want all of the NameId's to go into a ListBox. After I get that problem sovled I am wanting to have the info in the PNotes attribute to be displayed in a TextBox when the connecting NameId is selected in the ListBox.
I think I have posted my question in VB6 forum. Sorry for that...I am currently working with MIDI files.

View 1 RepliesDoes the IO.File.Copy method preserve file attributes? Especially, if I have a write-protected file, will the copy be write-protected to?
View 1 RepliesI have an application that uses a text file for its settings. This file is placed in the application folder but deployment sets its file attributes as "Read Only". I have to manually change this attribute every time I deploy the application or an upgrade. I tried (successfully) to place the text file in the "Documents and settings|All users|Application Data" folder, creating a specific folder for my application in which to place my file. The folder and file were created by the setup process but then, users who did not have admin rights still did not see the file, let alone open it.
I have gone back to placing my text file in the [Programs files]|[Manufacturer]|[Application name] folder but am saddled with manually changing the attributes. Is there a way I can do this programatically during deployment (e.g. by some post-deployment process)?

The following function copies a file from Source & Path to Dest & Path, normally setting file attributes to normal before copying.Yet, a user of my app has reported it to fail when copying readonly files, returning a permissions-related error. The user is however running the code as administrator, and the error happens - quite strangely - on the SetLastWriteTimeUtc line.Although the code reports that the file attributes are set to normal, windows explorer shows that they are set to read only.
[Code]...
I have a little vb.net script that will copy a file, set its attributes to Normal, update the file time, and then set back the attributes to match those of the source file.
If IO.File.Exists(Destination) Then IO.File.SetAttributes(Destination, IO.FileAttributes.Normal)
IO.File.Copy(Source, Destination, True)
IO.File.SetAttributes(Destination, IO.FileAttributes.Normal)
[code]....
I however I'm encountering a quite strange problem. On some configurations, IO.File.SetLastWriteTimeUtc triggers an UnauthorizedAccess error, although the IO.File.Copy instruction worked very well.
I've got an issue with an Access97 replicated database that I'm writing a small monitoring app for. I've got FSW's to track changes to the necessary files, but am having some issue in enumerating exactly what has changed in some instances, specifically when attributes may have changed. I'm using a similar strategy to track this as I did for changes in size. I've got a Private class variable for the size of each file and a local method variable and compare the two, when different, update the class variable for the next comparison.
