I am trying to convert text inputed in a text box to unicode. I need to the program to process each letter and return "the letter = the unicode" in the label.
For example, if the user enters "apple" the lable would read: a=65 p=80 p=80 l=76 e=69
I know the AscW command will return the Unicode Integer but I only know how to do the conversion for single letters
The code below only processes the first letter and only returns the code, not "the letter = the code"
Private Sub btnCode_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnCode.Click
Dim strWord As String = Me.txtWord.Text

What is the source code to display Unicode text in a textbox?
I basically know how to display ASCII code in a text box, but I'd like to be able to display Unicode in a text box.
I ran across my first unicode data, and I am not sure what to do with it. I read the unicode text from a binary file using the ReadBytes method, because ReadChars threw an exception when it tried it. Well, long story short, I have found a way to work with the data, I can convert it using a small Function I wrote, which goes something like this: [Code] And this works wonderfully. It just throws away anything not in the ASCII range, including the BOM at the start of the unicode data.
But I would guess that this method is not very universal and probably not the best way. Are there any VB functions available to do this sort of thing? I was able to find something called Text.Encoding, but there didn't seem to be a reverse of that not that I found anyhow. Any ideas?
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 have a VB2008 programme that accesses and stores data in a MS Access (XP) Database. I also live in the UK and am use to our funny old ways with dates (today is the 5th April 2010 so I want the Short Date as 05/04/2010 not 04/05/2010)
I am using the following code
Dim d1 As DateTime = DateTime.Now (#04/05/2010#)
Dim why As String = FormatDateTime(CDate(d1), DateFormat.ShortDate) which is 05/04/2020
UpdateRecord("latest", why, "backups", (index value in the table)
The last line runs an SQL query to update the table column latest to the date today but whatever I do to get the date as 05/04/2010 it is saved as 04/05/2010. I have tried setting the culture to "en-GB" at the start but this does not work. It does not matter if the latest column is in Date/Time or String format
