View 1 Repliesi'm trying to read the details information from various audio formatted files, most of which are mp3s. specifically i'd like to be able to read the title, artist, and # for a few hundred files that need renaming and resorting, so i'm trying to start with a single file.basically, if you view the properties of any mp3, and go to the details tab, all of this information is listed. i need to grab it programatically using visual studio 2010

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...
View 11 Repliesm_ArchiveBoolean, m_HiddenBoolean, m_ReadOnlyBoolean, m_IndexedBoolean, m_CompressedBoolean are all form level booleans that's set from their appropriate Checkboxes on the form before this code runs in a BackgroundWorker.
Why is it that this code works:
Try
Dim fi As New FileInfo(element)
With fi
If m_ArchiveBoolean = False Then
[code]....
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.
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:
[code]....
This works fine for getting the wave file info, It just doesn't display the numSamples which I need.
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:
<?xml version="1.0" encoding="UTF-8"?>
<!-- Do not edit this file -->
<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. Could someone show me how to get an audio file attributes such as; BitRate Attribute and Duration Attribute.I need to read those informations to be able to synchronize my Metronome with the music file tempo.
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.

I am building the 'TheBeerHouse' project in vb.net (the book is written in C#). Once I understand the concepts, I can usually convert it to vb. However, there are a few areas that give my some problems (which I will address individually). The first issue I have is the C# 'base' to VB 'MyBase'. [code] My understanding of this conversion is that I need to grab the attributes of the <articles> element under the <theBeerHouse> custom section in the web.config file.This code does not compile and the get the following error: 'MyBase' must be followed by '.' and an identifier.

View 1 RepliesI'm writing a class-library in VB.Net and one of the subs that are being called from the application which is using my library has more or less the following syntax:
Public Sub LoadDict(ByVal PhoneticType As String, ByVal strDict As String)
where PhoneticType can be phonSoundex, phonDoubleMetaphone or noPhonetic
I want to give the application-developer a possibility to select the PhoneticType from a list when writing the call of above sub (I think it's called attribute-arguments). This would make it easier for the developer since spelling-errors can be avoided and which will avoid errors when using the library. I think it's all about attributes but I haven't managed to get it to work despite trying.

View 10 RepliesHow can I change the attributes of files. Like the command attrib on cmd?
View 3 RepliesI'm writing a VB program that will delete the contents of several folders, but it leaves the top folder. For example, after graduation and summer school, we delete the folders that belong to the (now) prior students. Also, we retain the folders for the returning students, but we delete the contents of their folders. Every year, all students start out with empty folders. We do this practice to manage our disk space.
With a read-only file, via code, I first change the attributes of the file to normal and then delete it, via
