I am trying to write a function which has the ability to decode a string from utf8. I am getting the string as a response from a webserver.I am using the following line to do the decoding:
DecodeReply += System.Text.Encoding.ASCII.GetString(System.Text.Encoding.UTF8.GetBytes(temparray(i).ToString))

I have the following code:
Dim lStatementText As String
Dim lStatementString As New System.Text.StringBuilder
lStatementString.Append(RndRes.Forms.txt_request)
lStatementString.Append(" ")
lStatementString.Append("<b><a>")
[Code]...
Where Request.ID, Request.Description and also RndRes.Forms.txt_* are all strings. I want to display the string I build up here in a Infragistics FormattedLinkLabel. The problem is that if any of the strigs from the Request class contains a HTML character, the label is not displayed properly and the HTML encoding is broken.I need to find a function that masks the HTML codes.
I am trying to encode and decode using the unicode language and I don't know why I am getting these errors.

I have a call to Server.URLEncode(string) from an old asp file that stores user input into a table. In this case it was a string of Chinese charters.
The actual data is :
%E8%B0%B7%E6%AD%8C%E7%9A%84%E5%89%8D%E6%99%AF%E9%BA%A6%E5%85%8B%E6%96%AF%E9%9F%A6
I rewrote the code to vb.Net and after I get the data from the table, I call
HttpContext.Current.Server.UrlDecode(string) to decode the string, add it existing mark up for an email and send it on its way.
Note that with Visual Studio i can see the HTML markup as it appears in the email, and ALL of the Chinese data is EXACTLY as I would expect it.
When the emial is received i get "???????????" characters where there should be the Chinese characters.
What I do not understand:
What Server.URLEncode actually encodes the data to. It appears to be HEX.
What the array of "?" means in outlook or any other email system that opens it, I assume it means "Hey i cant convert this stuff, so here is a question mark for kicks, good luck."
I'm working on a website where we'll be getting a lot of videos to be uploaded. To keep things simple and secure, I'm just writing VB.net windows app to suck all the files in a directory in, allow you to set some options, and start the encode by spawning a new FFMpeg process.

I've been developing a SAML 2.0 SSO. I got a problem in decoding 64Base string to convert it into an xml then read the content later on.Below is the code I've been using:
Protected Function uf_getIDFromSAMLRequest(ByVal as_samlRequest As String) As String
Dim ms As New MemoryStream(Convert.FromBase64String(as_samlRequest))
[code]....
Say only &, ?, /,.
I want the rest to remain intact, including chinese or japanese characters. Those can be inserted into get just fine right?
I've made a class to encode a string
Public Class UTF8
Public Shared Function encode(ByVal str As String)
Dim utf8Encoding As New System.Text.UTF8Encoding
Dim encodedString() As Byte
encodedString = utf8Encoding.GetBytes(str)
[Code]...
Return encodedString.ToString() always returns "System.Byte[]". How could I get the real UTF-8 String?
all ` should be replaced with `` right? Well, is there a function built in by vb.net that does that sort of thing already?

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

View 1 RepliesI have to provide a client with a method to retrieve data from an Audiometer. The equipment is discontinued, but they have six of these and are used every work day. Using port monitoring and the DUMP command on the peripheral I was able to read the data and save to file. Now my challenge is decoding each line. It appears that only a section of the string is not in plain values.I added the pipe separators for clarity. I have determined those columns are: EMPID | DateTime | TechID | Results | ResultType = Test.[code]

View 10 RepliesThis is kind of a brain twister. First, what it involves. I'm writing an application that is working with values sent to and received from an 8 bit micro-controller. There are 8 bits of specified values. Here they are. bit1 = 1, bit2 = 2, bit3 = 4, bit4 = 8, bit5 = 16, bit6 = 32, bit7 = 64 and bit8 = 128.I made a routine that uses 8 checkboxes to add the values for sending them to the micro-controller. That wasn't too hard. In my appp there are 8 checkboxes. Each checkbox assigns one of the specific bit values to a variable (or subtracts it when unchecked). The total of the variable is then displayed in a textbox and ready to send.Now the hard part that ed to take any number between 0 and 255 apart in values that will be a combination of the numbers (1,2,4,8,16,32,64,128) above and show each checkbox which is assigned those numbers to be checked.
