Did anyone already try to read RFID tags but not by reading request?I mean, When some tag is readable can't just the RFID reader detect it?So far this is the code I've been trying to use without success.

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

I'm trying to make an application that can read a 12 byte hex string from the serial port and display it into a text box, the source is a RFID module that is connected to my USB port using a RS232-USB converter.My first problem was accessing the text box in the datarecieved event due to invalid cross-threaded operation. Upon googling that, I copy/pasted the code I needed to get it work, these are all the cross threading functions.The OpenPort function and Datarecieved event are my own code, the rest I got off google. The application then worked, but I would get an incomplete code, the first swipe I would get all 12 digits, and at every other swipe, the first byte would vanish. Upon some more reading, I decided to make an array, the size of the incoming data (shown in the code below), but now I get the cross-threading error again.I know there's something wrong with the way I'm using the array. This is way beyond my VB knowledge, and I'm in o I'm an electronics engineer and self taught myself a little programming to create some apps for my hardware.Updated code:

View 1 RepliesI remember seeing a tutorial on reading XML somewhere and took no notice of it because I have my own way of doing things. In this tutorial the author outlined a basic way of reading certain XML nodes using tags
For example,
<Root>
<Person tag = 1>
<name>John</name>
[Code].....
Now in his example one would be able to navigate to John's "person" node by using the tag value. I had hoped I would never have to venture away from my warm and comfortable way of working with XML but because of an annoying datagrid and uncooperative XML format I've had to rethink things.
i have an application that loads a bunch of Mp3 files and then plays them. What I want to do is use a listview to display filename, album, artist and location. Now I can get the information into the listview no problem. BUT, I don't know a simple way to read in the ID3 tags from an Mp3 file.
View 3 RepliesI 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 am making a small utility to rename my music library to the same syntax (00-Artist-Album-Title.mp3). All the files are MP3 and are correctly tagged (ID3). This is my current

View 3 RepliesI have several files that I am reading in and 'scrubbing'. The scrubbing is simply taking certain HTML tags and changing them - no big deal.When I read in the files (one at a time), they read and then I scrub them.The files stop reading mid-way *no matter what* the encoding type There is no stop character or anything, it is simple HTML and I do not see any reason why the file isn't being read I have attached one of files that is having a problem and the code is quite simple:
Dim oRead As New System.IO.StreamReader(Dir & "" & FN, Encoding.ASCII)
EntireFile = oRead.ReadToEnd()

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 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 want to read ALL text between specific <b1> and </b1> tags + hide the tags, example text:As part of the Visual Studio product range, Microsoft created a set of free development environments for hobbyists and novices, the Visual Studio 2005 Express series. One edition in the series is Visual Basic 2005 Express Edition, which was succeeded by Visual Basic 2008 Express Edition in the 2008 edition of Visual Studio Express.[8]The Express Editions are targeted specifically for people learning a language. They have a streamlined version of the user interface, and lack more advanced features of the standard versions. On the other hand, Visual Basic 2005 Express Edition does contain the Visual Basic 6.0 converter, so it is a way to evaluate feasibility of conversion from older versions of Visual Basic.

View 11 RepliesI've almost finished my multimedia project. On the photobrowser (which constructs thumbnails of every photo in a folder and draws them onto a bitmap which I then make persistent and from which the user can select a thumbnail and the image is shown in full on a new form). You can print the bitmap consisting of 100s of thumbnails or the full image associated with a thumbnail. The onloy thing missing is getting all the Exif info - which is proving more difficult than I expected despite the propetyitems in vb.net. Yes, I have set the encoding to UTF8 etc.

With my code as I have a trouble with the returned strings that I have extracted from my php source to add the strings in my listview.
I'm reading the tags of mystrings1 and mystrings2 for each paragraph from the php source. I got the returned strings which it looks like this:
PHP
<p id='mystrings1'>my strings</p> | <a href="http://xfvasfasfasfasf">Link</a> </td> | <a href="delete.php?id=0">Delete</a> </td> | <span id="mystrings2">Enabled</td>
I want the returned strings to be like this when I reads the tags of mystrings1 and mystrings2 while ignore the other tags.
PHP
<p id='mystrings1'>my strings</p> | <span id="mystrings2">Enabled</td>
Here's the
Public Sub timer1_Tick(ByVal sender As Object, ByVal e As System.EventArgs)
timer1.Enabled = False
timer1.Stop()

Do you know how I can ignore the other tags when I get the returned strings of mystrings1 and mystrings2?
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.
