Detect The Encoding Of A Stream?
Sep 6, 2011I 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.

Asp.net - Convert The Encoding Type Of A Stream In .NET?
Dec 27, 2010I ve the following stream but I don't know its encoding type because the stream reader detects encoding from byte order marks
Dim reader As StreamReader = New StreamReader(respStream, True)
so how can I detect the encoding type AND convert it to another type? (for ex. from ASCII to UTF8)
PS: What is the difference with the following line?
Dim reader As StreamReader = New StreamReader(respStream,
Encoding.ASCII, True)
Possible To Detect UDP Response Encoding?
Jan 16, 2010I query a Quake3 masterserver via UDP, and get the response as below.As you can see, I had trouble figuring out the encoding of what the server sent...Is there any way to detect or set the receive encoding ?
baBuffer = new byte[1024*100]; // 100 kb should be enough
int recv = sctServerConnection.ReceiveFrom(baBuffer, ref tmpRemote);
Console.WriteLine("Message received from {0}:", tmpRemote.ToString());

Detect Silence Of Audio In Buffer Of WMA Stream?
Aug 24, 2010I have a standard WMA stream, streaming in constantly via the internet. I need to write an application to stream this audio, and looks for any periods of 'silence'. When it detects silence, it runs an event.
For the purposes of this, silence is defined as three seconds of zero-level audio. The stream keeps going in a technical sense, but there is no audible noise coming through it.
However, I want the program to detect the silence while it is still in the 'buffer'. That is, the user won't hear this silence before the program detects it is there.
The audio shouldn't stop as it is analysing this silence - it needs to keep playing the audio constantly to the user.
I'm open to using whatever suitable API is out there - such as BASS, or the Windows Media extensions built into the dot net platform.
EnCoding Message To DDE Client Using System.Text.Encoding.ASCII.GetBytes (message)?

Stream Read Return Length 0 While Stream Is Open And Has Valid Data In It?
May 25, 2012in an winForm app in VS2010 win 7 compiling to x86, I try to do what Alvas.Audio seems to work. See (c# ex: [URL] for reference.
Dim data() As Byte = wr.ReadData(second * i, second)
The result give me data.length()=0. I do not have any exception, I can read format from it and whatever reader I use I got this problem.EDIT : After some tests, it seems like the uncompressed file I create in the first step (in PCM format, with .wav extension) can not be recognized by the Alvas.audio library for the second step. I must miss something around Audio file markups or something alike.
Here is the code that might be the source (basically this is step 1):
Dim functOut As String = String.Empty
Dim wr As Alvas.Audio.IAudioReader = Nothing
Dim fs As IO.FileStream = Nothing

View 12 RepliesC# - Text Encoding (In .Net)
May 3, 2011I 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?

Base64 Encoding Images In CSS
Apr 20, 2012I 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]

Encoding - Prevent .net From Differentiating à To A?
Mar 20, 2012We 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.
Encoding From One Encoded Format To Another?

Right Now I am able to detect the encoding but conversion not happening.
Encoding Issue? VB 2005 And VB6
Jun 2, 2009I 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.
Encoding One Character Wrong
Jun 16, 2010I 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.
