Ampersand (&) In Data - Does It Need To Be Encoded
Jan 11, 2011
I have a data table being returned that populates a repeater. One of the fields has the & character in the data and displays perfectly within the asp:literal on the screen. The source shows the & character un-encoded.My question is this: Does it NEED to be encoded? A co-worker is insisting that it must be encoded in order to be "HTML compliant". But it works perfectly for display purposes. Is this REALLY required for any type of compliance that I should even be worrying about?

I have created a program in Visual Basic using Microsoft Visual Studio 2010 Professional. There is a textbox that I use in the program that when the focus is placed on it will take the data encoded on a magnetic striped card such as a driver's license or any card that has this kind of data encoded magnetically. Very simple to get the data as the program takes all of it upon the swipe without having to do really anything, however, the problem is that I don't know which declaration to use when the swipe has stopped - or the last character has been entered. Currently I am using TextBox1_textChanged as my declaration, but that is called every time each character is put into the text box. When you are swiping, this is an ongoing process until the last character is put in. So if I have a magentic card with 10 characters in it, this method will be called 10 times. Is there a declaration that I can use that only fires off whent he swipe has loaded all of the characters or some kind of loop that I can incorporate?

In my program I have a linklabel that is used for local directories and it gets the directory from an XML file, but whenever there is an ampersand in a directory name I get errors. I've tried adding "ToString", having two ampersands (&&), and puting quotes around the directory in the XML file, but it doesn't work. Is there any way for it to treat the ampersand as a regular character? Here's the code that pertains to the directory path
'this part loads the xml file and sets the inner text to the proper variable
'let's pretend the directory in the XML file is "C:\foo & bar\"
doc.Load(Application.StartupPath & "\Anime\" & title)

I've tried:
Const amper As String = "" & ""
ToolStripButton1.Text = "Save " & amper & " Close"
and also replacing the "amper" with Char(38), but it doesn't show up. This is the full
Private Sub Dialog1_Load(sender As System.Object, e As System.EventArgs) Handles MyBase.Load
'Save and close button text
Const amper As String = "" & ""
ToolStripButton1.Text = "Save " & amper & " Close"
End Sub
Am I using both methods wrong?

What's the trailing ampersand on VB hexadecimal numbers for? I've read it forces conversion to an Int32 on the chance VB wants to try and store as an Int16. That makes sense to me. But the part I didn't get from the blurb was to always use the trailing ampersand for bitmasks, flags, enums, etc. Apparantly, it has something to do with overriding VB's fetish for using signed numbers for things internally, which can lead to weird results in comparisons.
So to get easy points, what are the rules for VB.Net hexadecimal numbers, with and without the trailing ampersand? Please include the specific usage in the case of bitmasks/flags and such, and how one would also use it to force signed vs. unsigned.

I have a cookie saved to the user as follows.[code]...
The SearchText stores a value they have input in a previous page. We have observed if there is an ampersand in the cookie (eg Tyne & Wear), then the cookie doesn't save subsequent values (SearchType).

Is there a problem with an ampersand in the name of an MSSQL table name.? I'm converting an Access db to MSSQL and a table like Ta&ble1 gets upsized to SQL Server no problem. Do you guys see this as a problem in subs that use a reader when used with a stored procedure that uses this table?

what is the meaning of the Ampersand after Boolean in "Result as Boolean"? Also I have seen a question mark after Boolean in some 'Dim' statements. What does that mean?

I have a challange to convert the detected Encoding format of Text file to selected Encoding format. Like if the detected file is in Utf-8 and if user want to convert the encoding to Utf-16 or ANCII or Unicode. It will happen on one button click and the file will convert to the desired output encoding format.
Right Now I am able to detect the encoding but conversion not happening.

I have an example of standard text (in Hex form) in a specific encoding (selected by the user). And I have a weirdly encoded text which is in the same encoding but a little different. How do I convert the Standard to the encoded Hex?
Cyrillic (ISO-8859-5) Example:
## 12 91 BB BE BA B8 C0 2E 20 CD BA C0 B0 BD B0 20 B8 20 BA BB B0 B2 2E <- ALTERNATIVE
B1 DB DE DA D8 E0 2E 20 ED DA E0 D0 DD D0 20 D8 20 DA DB D0 D2 2E <- STANDARD
Diff. from Standard (in Decimal): -32
Hebrew Visual (ISO-8859-8) Example:
## 1C 0B E0 E2 D9 DC EA 20 DE E1 DA 20 D5 DE E7 E9 D9 DD <- ALTERNATIVE
F0 F2 E9 EC FA 20 EE F1 EA 20 E5 EE F7 F9 E9 ED <- STANDARD
Diff. from Standard (in Decimal): -16

I have a scenario where i have to Parse a UTF-16 Encoded CSV file and populate a treeview using VB.Net. I need to parse the CSV files which may also support other languages. how to proceed on this and what classes of .net I can use to solve this issue.
In VB.Net we do not have a provision to parse a UTF-16 file But There is a provision for reading UTF-8 encoded file.The method is OpenText(). I want a similar method but it should parse or read a UTF-16 encoded file.

I am writing some rest calls to the LinkedIn API using web request and have hit an encoding issue.The LinkedIn API takes requires an encoded URI as one of the parameters on the lookup i am trying to run.
We are calling the api through .Net's WebRequest.Create; and when we pass in the URI it decodes it and as a result we can't get the data from the call. Im trying to open a URI like this[URL]..Is there a mechanism in the webrequest class to stop it decoding the passed in URI; or a work around for this?

I have to read a 2D barcode that's encoded with base256. When I scan the barcode, it sends different characters as it comes from the keyboard and it changes the focus, turns visual studio in full screen, give the command to send to printer from notepad++.
I guess it reads ALT + TAB, CTRL + P, ALT + SHIFT, etc. and i can't capture all the bytes from the barcode.
I tried to capture the event on textbox KeyPress method with e.handled = True and e.keyChar added to the bytes()
On form.load I set:
Me.KeyPreview = True
And tried also on form.KeyDown with no luck.

Question: In order to store logos in a database and display them dynamically in ms-reporting service, I need to base64 encode the image. It doesn't work with binary saved images, due to MS limitations...
Now my question: Which datatype do I use? Varchar, nvarchar or text? I guess varchar would be good enough, since base64 encoded, but images might be larger than 4000 characters...

I have come across some Base64 conversion functions in .net(FromBase64.string etc). What i want is, for a sample, i have a base 64 encoded string as
"48YwojCi4yaiow==".
I need to convert this string to the corresponding Hexadecimal text(The sample stands for "Thisistest" in hex text) The below link is an online converter from base64 to hexadecimal text. If you give the same base64 encoded data in the link , click on convert, the one that is seen below "Hexadecimal text" is what I need.

Is there a standard library function in vb.net which does this? Converting a base 64 data to a hexadecimal text?

Greetings, I'm looking for a way to encode a string into HTML that uses human-readable tags such as ê (=ê). At the moment, I am using the HttpUtility.HtmlEncode() function, but it appears to return numbered tags instead of human-readable ones. For example:
Dim str as string = HttpUtility;HtmlEncode("vente - en-tête")
'Expected: vente - en-tête
'Actually received: vente - en-tête
Is there a setting or function in ASP.Net to encode a string into HTML resembling the first comment?
EDIT: I am looking for this kind of functionality because the text is saved HTML-encoded in the database. The text comes from a bunch of MS Word documents that have been converted to HTML.

I'm having an issue with trying to use VB.NET and the WebRequest object to post some cXML text and an attachment.I believe I am formatting the text of the data I wish to post correctly, as it matches samples Ariba has supplied. What I am uncertain of is if I am correctly using the WebRequest object to do the posting.I am setting the Method as "POST" and the ContentType as "multipart/mixed".I can successfully post cXML (using a ContentType of "text/xml") The message I get back from Ariba is "The document could not be parsed: Missing start boundary [ANCLS-741552]", however, as the following code shows, there is a start boundary.I have removed some proprietary data and replaced it with "...". Following the MIME text, I have included the relevant VB.NET code I am using.[code]

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.
