Mar 26, 2011
i got a problem when receiving data from networkstream that was converted from bytes to string.. the output would be the same but when i compare the the string generated from Encoding.ASCII.GetString() compared to the actual string, the output is not the same..
This is my code..
Server:

Client:
CODE:
just for ping purposes.. :)
my server pings to client..is there any instance that when the string will be converted to bytes, the string will change?

My system has Japanese regional settings. I have used this as default encoding in my code. But Encoding.GetString() method doesn't return proper length because of DBCS.[code]

I would like to pass a whitespace character by using the System.Text.Encoding.ASCII.GetBytes(" "), and System.Text.Encoding.Unicode.GetBytes(" ") , where " " is the whitespace Character required. What do I need to type (" ") to get a whitespace character passed.?

I am sending a DDE message to a client using System.Text.Encoding.ASCII.GetBytes(item) . However, before the message is actually sent, I would like to get the message coded where if the item="Ask" then item=Ask (string variable) and so on. The code is:
Protected Overrides Function OnRequest(ByVal conversation As DdeConversation, ByVal item As String, ByVal format As Integer) As RequestResult
' Return data to the client only if the format is CF_TEXT

I am writing a console application, which reads emails from different email boxes and processes through them. Emails are received from various automated systems. The email messages are logged and/or sent forward.
The problem is that some emails are encoded in UTF-8 and transfer-encoded in quoted-printable which messes up special characters (mainly ä,ö and å). I have not found any solution to convert them in readable format.
For example "ä" in quoted-printable is "=C3=A4". Using a normal conversion methods the result is "ä" (gibberish).
I shamelessly ripped this example conversion table from here: [URL]
[Code].....
So how do I get the real codepoint from UTF-8 value? I'd rather not use any external libraries. Besides I've tried a couple already and they failed.

I have a function in my WinForms app that needs to retrieve the user's default user agent. To do this, I've created a web page (ASP.NET) that displays the user agent in a Label in the Page_Load. The problem that I'm having is that when I fetch the HTML from that page, the result includes all of the HTML except what should be displayed in the LabelHere's my
Private Function GetUserAgent(ByVal theUrl As String) As String
Dim proc As New Process
proc.StartInfo.CreateNoWindow = True[code].......
However, when viewing the page's source in a browser, it contains the following .Your user agent is: <span id="Label1">(user agent string here)</span></p>.why GetString is not picking up the Label contents?
Note: For reasons beyond my control, this app is coded using .NET 1.1. Otherwise, I'd be doing things a bit differently.

I am using Microsoft.VisualBasic.Fileio.TextFieldParser to parse a CSV file that was created with Excel 2003. The parser is working great with the exception that it is converting extended ascii values to question marks! So if the file content was:
± 3
The TextFieldParser is returning
? 3
I have tried all of the encodings in the System.Text.Encoding package with no luck. I thought I had it with UTF7 but it was dropping other characters like replacing the + sign with a space.

I'm working on decoding a NMEA sentence that is a compressed 8-bit string. I'm having a very hard time of wrapping my head around the bit manipulation needed to convert this string. If someone could get me started with this it would be great.
Here is the incomming string:
!AIVDM,1,1,,A,14eG;o@034o8sd<L9i:a;WF>062D,0*7D
and here is the expected output:

So I have an ASP.Net (vb.net) application. It has a textbox and the user is pasting text from Microsoft Word into it. So things like the long dash (charcode 150) are coming through as input. Other examples would be the smart quotes or accented characters. In my app I'm encoding them in xml and passing that to the database as an xml parameter to a sql stored procedure. It gets inserted in the database just as the user entered it.
The problem is the app that reads this data doesn't like these characters. So I need to translate them into the lower ascii (7bit I think) character set. How do I do that? How do I determine what encoding they are in so I can do something like the following. And would just requesting the ASCII equivalent translate them intelligently or do I have to write some code for that?
Also maybe it might be easier to solve this problem in the web page to begin with. When you copy the selection of characters from Word it puts several formats in the clipboard. The straight text one is the one I want. Is there a way to have the html textbox get that text when the user pastes into it? Do I have to set the encoding of the web page somehow?

I have done very little with encoding of Text. Truthfully, I don't really even know what it means exactly.
For example, if I have something like:
CODE:
Is that 'encoded' in memory in a particular format? Does that format depend on what language I'm using?
If I were in another country, like China, for example, and I had a string of Chinese (mandarin? My apologies if I'm using the wrong words here) would the following code (that I've used fine on English strings) still work the same?
CODE:
Or would it lose all meaning when you convert that .Net string to a UTF8Encoding when that conversion isn't valid?
Finally, I've worked with .Net for a few years now and I've never seen, heard, or had to do anything with Encoding. Am I the exception, or is it not a common thing to do?

I'm using this code to convert string to ISO8859-1

But the problem is when an user writes this caracter:
EXAMPLE:

I think that my code is wrong. Because if I send the same string encoded "price+80%2BVAT", Why in VB.NET code not runs and in PHP runs fine? Is the same encoded string.

I am writing a little project to parse a CSS file, and base64 encode all the background images.While I am able to parse the CSS correctly, it seems that everytime I try to convert the image file into a base64Encoded string, the string returned is always exactly the same.Please assume that all image paths are passing correctly to the method. In this instance, all images are fully qualified urls, so the first section of the method is what is doing the conversion.[code]

I would like to know the way a stream or a string is encoded before converting it. If a string is not utf-8 it would be converted to utf-8.

We know a tolower function will turn all A to a How to turn all à to a.The purpose is I am creating ids for databases and id need to be unique. Sometimes the same stores are written as à in one place and as a on other places. This will create duplicate id problem.So I need a function that will turn all à and all of it's variation into a. The same way ě should become e.
Basically I would use utf8_unicode collation on my databases. Letters that count as the same letter under that collation should map to the same character under this function.I need to make sure that all other east asian characers are not affected in anyway.

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 application that collects a signature on a handheld device, saves the data as a byte array and transmits it to the pc. This came originally from a sample from MS. The sample works fine.In my case I am sending this signature back to the pc where it is received by a VB6 application and stuffed into a database and then there is a dot net program that can or should be able to pull that data and reproduce the image.
Due to certian characters that may appear in the data such as ' " Null and such I run a little replacement routine on the data before I save it on the device and run the reverse before I try to rebuild the image. This also seems to be working.
Now if I save the data as a file on the device and load that file into my viewer the sig shows up just fine. It works with both the file that has had the replacements done as well as the one which has not. However when I transfer the data via my vb 6 application the sig is then distorted when viewed.
I have written the data to file as it comes into the pc and again after it has been parsed and in both cases it does not match what was actually in the file on the device that is being sent and I can not for the life of me figure out what is going on here.
Code:
sBytes = Encoding.Default.GetBytes(DataString)
bSent = wSocket.Send(sBytes)
Code:
Winsock1(Index).GetData strData, vbString
When I compare the file created on the handheld device with the one created ont he pc from the data received it gets odd. In text mode both files look alike even with the terminal font enabled but in binary mode they are different.The first noticable difference in Hex View is a ways into the first line the file from the handheld device has C3 A0 but the file written on the pc has E0 instead from there on all bytes are shifted by 1 yet when I look at it in text view no bytes are shifted and the character displayed where C3 A0 is in one and E0 in the other is the same accented a character.

I have a byte array that I'm encoding to a string:[code]Then I write that to a file via IO.File.AppendAllText.If I open that file in 010 Editor (to view the binary data) it displays as this:47 43 44 53 79 73 74 65 6D 73 3F 0A 01 32 31 36..The original byte array contained 89 at position 11, and the encoded string contains 3F.If I change my encoding to Encoding.Default.GetString, it gives me:47 43 44 53 79 73 74 65 6D 73 E2 80 B0 0A 01 32 31 36.

What I have is a program that is receiving an image from my webcam 4 times each second.. What I am currently doing is just forwarding that image to a picturebox on my main form.. I do not keep the image in memory so as not to clog it up.. When you look at it seems like a video feed. Now what I want to do is to take that image every time it comes.. and put it into a video file, so as to record everything that is being seen by the camera.. Is there any way to encode a video preferably avi or mp4 video..

I want to save a HTML file to MHT file. Now, it is done with CDO object I googled. But, I want to save the MHT file with indicated encoding by myself. For example, the content in HTML file are Chinese word; if I save as the HTML to MHT in IE, the content in MHT are encoded by GBK (it are hex word instead of Chinese word); if I save as the HTML to MHT with CDO object, the content in MHT are Chinese word.
