VS 2010 - Retrieving Metadata Of Individual Files
Oct 6, 2011
I'm using VS2010 Express. I have a VB.net project, where I need to find the metadata of individual files; Artist, Author, Comments, etc. (Specifically I need to find the video length in time of .wtv files). I have searched, but could only find VB6 examples and other code snippets that simply didn't work as they required some retired com or dll to do it. How do I do it in the latest VB.net? NOT VB6, C# or anything else. VB.Net in Visual Studio 2010 Express.

Early on the OP was asked "how will you get the data about your music?" and it went into a whole other direction, but that's what I'm here to show: Another way to get the data about your music without dependence on the metadata.The music that I have has fairly extensive tags embedded but as I've discovered, that's not the case with all of them. It's a good starting point I suppose but is there another way? Let me jump to the end, then in the next several posts, we'll dissect the parts of it. My goal was use "only out of the components and methods" and this is what we end up with: Aside from the rudimentary things like song duration, how about if we could get a host of information about the songs, including the cover art? As shown in the example above, some also will have a link to additional information. The additional information may even contain a way to watch a music video for that song like this: Further, some will even contain what I call "Liner Notes" like this:
If this interests you, read on ...This isn't a new thought at all; I've explored this area before. Have a look at this on Code Project. Now before you go thinking that you've found the keys to the kingdom, I should explain a little minor issue about that - it doesn't work! In that, he relies heavily on three web services: Amazon Web Service MusicBrainz LyricWiki Amazon has significantly modified their service such that his methods don't work now. If you follow the posts following the thread, you'll see a few people have tried workarounds but over the years, even those stopped working because apparently they (Amazon) are in a state of flux regarding their API. LyricWiki is still alive and well, but - the music recording industry forced them to no longer offer their service to developers. MusicBrainz is in fact a heck of a resource and if you're at all interested in this topic, I would encourage you to have a look around. It's odd to work with, but it's chock full of good information and they're constantly adding to it or so it seems. All that said, this example won't use any of those but rather a different service all together: Last Dot FM. I can't say that I know much about them, but I happened onto them a few months back when I was first experimenting with all this stuff.

Is there way to set custom metadata to files of any type? I want the metadata to be copied when the file is renamed, moved or copied. I don't want to use ADS.

In windows explorer on Windows 7 (and Vista I believe), when you click on a file the bottom pane shows the files metadata. What I am particularly interested is the files Tag. If you click into the tag field, Windows will give you a list of tags. The list appears to be random and incomplete. So I have two questions. Is there a way to retrieve a list of a file tags on the system and is there a way to add to the list of tags in the Windows file pane?

Does VB 2010 offer native support for reading and modifying ID3 metadata in MP3 files? A brief search through MSDN shows me nothing, and I see someone says he had to write his own library of code for it. But that was some years ago, when you had to write code to access JPEG Exif metadata, and I know that's changed with the Image class and the GetPropertyItem method; so I'm hoping MP3 files have their own methods and properties now for this.

I'm editing jpg metadata and when I'm finished the file is less than half the size but ok, IE I can see modified tags correctly via windows explorer. But if I edit the same file again its down to 16k and corrupted. The image being edited is the standard desert.jpg found in the picturessample pictures directory.
I'm using the following
Public Sub Put_FileMetadata(ByRef glb_UserArray() As String, ByRef glb_SecurityArray() As String, ByRef glb_InputParms() As String, ByRef glb_InError As Boolean, ByRef glb_ErrorNumArray() As Long, ByRef glb_ErrorDescArray() As String)

I'm using this code to retrieve the list of files from a FTP server
Dim request As FtpWebRequest = WebRequest.Create("[URL]")
request.Credentials = New NetworkCredential(username, password)
request.Method = WebRequestMethods.Ftp.ListDirectoryDetails
Dim response As FtpWebResponse = request.GetResponse()
Dim responseStream As Stream = response.GetResponseStream()
Dim reader As StreamReader = New StreamReader(responseStream)
messagebox.show (reader.ReadLine)
It gives me alot of information that I dont need, I know that I can use:
request.Method = WebRequestMethods.Ftp.ListDirectory
Which only retrieves the file name but when I try to change it, it gives me an error. Error number 550. ListDirectory so I can only get the file name?

I'm creating a project but I only need exe's as my final thing. I don't know how to put it in simple terms, but here is how I need it to be..The main window remains open i.e.frmMain. ther other forms are only called by an external program (LanSafe UPS Software) every time something happens (Either batteries gets disconnected or power fails). Each of these forms have to be separate executable files. This application is for sending SMSs using Fusion 100 modem. Is what I need possible?

I have a notepad I'm creating, but i've tried everything I could think of to replace a tab indent with spaces on keys.tab event.When I press the Tab key I want it to replace the tab indent with 4 individual spaces. Like as if I was to press the space bar 4 times, only that would be done automatically upon pressing the tab key on my keyboard.
I'm using a richtextbox control. I have a tab settings form, where I will be able to give users an option to choose how many spaces the tab key will represent. I just need to figure out how to replace the {TAB}.
so far, I have the number of spaces correct, but the last space in the series after pressing my tab key seems a bit larger than the rest of the spaces, and is not a real (normal) space character. That puts everything out of line when i'm typing on a new line. the characters don't line up vertically and when I press the space key however many times i've set the {Tab} key to represent, the tab key even though it should have the same number of spaces occupies a larger distance horizontally if that makes sense.

I have a function that is suppost to take a list of strings then split up each part. This is my code
For i As Integer = 1 To UPdata.Count
If InStr(UPdata(i), "!!") Then
Dim DataTBP() As String
Do
DataTBP = UPdata(i).Split("!!")
[Code] .....
One section of UPdata would look something like
ABC#DEF@GHIHSJD!!143#ISJ@PSIODH!!
What I want it to do is firstly separate the lines using !! so i would be left with
ABC#DEF@GHIHSJD
143#ISJ@PSIODH
That part works fine and I am left with an array DataTBP() with 2 values. The strings found above. Its then suppose to extract the part before # for every string left in DataTBP (In my example two) but the function that's meant to do this:
For j As Integer = 0 To UBound(DataTBP)
Dim DataType As String = DataTBP(j)
DataType = DataType.Split("#")
Select Case DataTBP(j)
[Code] .....
Throws me the error
Value of type '1-dimensional array of String' cannot be converted to 'String'.
But I don't know why as DataTBP(j) is a string not an array but a string. I've also tried
For Each a As String In DataTBP
Dim DataType As String = a.Split("#")
Next
It throws the same error

I have decided to go down the MAPI / CDO or Winsock route in my application. Sending emails is easy enough. However, I need to retrieve and display emails. The slight twist in the tail is that I don't want to download / access all emails, just those from a certain sender's email address. Most users will have Outlook installed on the computer but i'd rather not rely on this unless I have to. I'm not sure which technology to use and how to go about this as I don't want to download all messages and then iterate through them. I'd rather just request emails with specific properties.
