I've been reading up on ID3 tags and was wondering had any suggestions on where exactly to start. I'm hoping to code an application to view, edit and save ID3 tags to and from mp3's. However I've found that there isn't a hell of a lot of information geared towards beginners on the internet. Am I correct in assuming that I would have to create a binary reader and read a certain amount of bytes from the beginning of the file? I'm just trying to get an idea of where to start.
I am using VB2008 and I am working on a project to read id3v2 tags. It can already read id3v1 tags, but the track name and artist are for maximum 30 characters. I want making it to read id3v2 tags?
I have been making a media player in vb.net. I need to get information from the Mp3 Tags. First I used ID3v1 tag reading class which I downloaded from somewhere I don't Know. Well it was working fine. it retrieved information like Album, Artist etc. but i need to get the lyrics as well. So I got news that ID3v1 tags do not have lyrics in them as a field. So I tried ID3v2 tag reading class but that too did not help. Can't find any class that can get me the lyrics.
I tried to fiddle with the classes but only ended up messing the whole thing.
I already have code to read ID3v1 and v2 tags. That's not the problem. I open an IOStream, locate the ID3v2 header and pull the bytes out. Handling unicode was a bit of a sod, but I got it working.
What I don't understand is how to remove an ID3v2 tag or write one out. ID3v1 is easy - just truncate the file, then append some bytes. Simple. But ID3v2 tags don't have to be at the start of the file, do they? It's conventional, but by no means mandatory. If I just crop the entire ID3 out of the file, and close the gap, will that work? And then, to write my own tags, should I just write the bytes to the front of the file? Or do I need to update other bits of the file so the player will know where the audio data has moved to?
Also, do I need to use unsynchronisation? How can I tell if I need to?
I've looked on CodeProject; I've googled; and I've read the specification on id3.org - which, by the way, is less than clear! For example, it says that the "Extended header size" can be 6 or 10 bytes in length. So um....how am I supposed to know which one? Is there some magic way of determining how many bytes this value is being stored as?

I have a problem reading ID3v2 text identifier tags when they are encoded in unicode. If i update the tags using winamp the tags are encoded in UTF-16 with BOM. When i try to read the tag i step through each byte and use chr(byte) to get the character that that byte represents. But when the bytes are unicode i get some characters (shown below) as the first two characters:
The remaining characters are correct, it's just these 2 first ones.
What are these for? and how can i get rid of them or read the bytes as unicode characters? i've tried reading the ID3 website and many other sites too but i don't know what to do. i can check the text-encoding byte in that tag frame to determine whether or not the tag is encoded in unicode or ISO-8859-1 but i don't know what to do next.
I'm trying to analyze web pages for seo. I'm trying to create my own personal tool to extract all the keywords and tags from web pages (a little clearer).I already know how to extract or parse links and text from web pages. The issue is that I tried to implement title tags, body tags or keyword tags in general via using the following code:
Dim theElementCollection As HtmlElementCollection = WebBrowser1.Document.GetElementsByTagName("a") For Each curElement As HtmlElement In theElementCollection If curElement.GetAttribute("href").Contains("http://twitter.com/") Then
[code]....
Try to extract all the keywords from the title, body etc. for this page:[URL] and send it to separate textboxes (title keywords in textbox1, meta tags in textbox2 etc.).

I was just wondering how to extract or parse any particual tags (whichever I specify) from webpages. I know how to extract text and links from webpages, but I tried to use the same method from the following code for div tags, title tags etcetera and it doesn't seem to work:
how to make taglib save certain tags that use arrays. For example when I save the album i can just type ID31.Album = txtalubm1.text. But if I want to save albumartist since its an array I cant seem to do it the same way.
I am planning to create a system for my case study wherein i can Add tags from images and search for it by "tags" such as photobucket. For example i open an image to my system, and it's file name was "WhiteHouse.jpg" and i added or tagged it as "Building". Once i search on my computer, and type the word/keyword "Building", the image "WhiteHouse.jpg" will be displayed on search results as i tagged it on my system.Is that possible guys? or i can only search by tags using my system/application? and not in the search command in my computer?If it is possible please tell me what to do. or if you have sample vb.net2008(windows Application) files it will be helpful. Or if you have sites related into it. pls send me those links, especially downloadable vb.net files w/ codes for further studying.

I'm using the ExifTools code to read and update the EXIF for JPEGs in a VB.NET project I am developing. So far I've been successful with doing what I need to but I'm having difficulty with the last thing on my wishlist- the "Keywords" or "Tags" entry. The "Tags" property (as accessed by file right-click->properties->Details and just below the rating stars) is populated with information but if I use the PropertyItem for Keywords (Value 40094) with the ExifTools GetPropertyValue() function, it returns nothing.
It's pretty obvious that the "Tags" entry under file properties is not the same thing as what EXIF defines as "Keywords" but I have not been able to figure out what the correct PropertyItem value to pass is.
I am trying to format xml entries I have so that I can use the xmltextreader without getting errors. I added a default header and footer in the event I notice there is no opening or closing tags. I remove illegal characters and check for unicode but I always find an issue where an entry slips in and gives the error:data at the root level is invalid and when I check that entry is slipped through the cleaning process or just has an unmatched tag somewhere. Now I use
Dim stringSplitter() As String = {"</entry>"} ' split the file content based on the closing entry tag sampleResults = _html.Split(stringSplitter, StringSplitOptions.RemoveEmptyEntries)
to split my xml into individual entries before I start the cleanup process. Here are my default headers;
