Converting An ASCII 6-bit String To 8-Bit ASCII Characters?

May 9, 2011

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:

Extract Ascii String From This Byte Array?

Sep 15, 2010

This illustrates a series of bytes that I've received from a socket and assigned into a byte array (frameData). How do I extract the ascii string from frameData if FrameData.Length is 79 bytes long and I need to extract the byte locations whose begin -frameData(26) and end frameData(44) are given by the arrows I've drawn?

Convert String Containing Upper ASCII Characters To Byte Array?

Oct 9, 2008

How to correctly convert string containing upper ASCII characters to byte array besides looping through each character and filling the array using AscW(chr)?I know I can do something like:

Code:
Dim bSourceData As Byte() = System.Text.ASCIIEncoding.GetBytes(sourcedata)

But this only works for lower ascii characters (0-127).Instead of ASCIIEncoding I can specify encoding myself (System.Text.Encoding.Getencoding(encoding).GetBytes(sourcedata)). But I have to specify correct encoding in this case, otherwise most of special characters are converted to "?". What should I do if I don't know the encoding?

Converting A String To A Byte?

Mar 10, 2010

I am using the .NET Framework 2.0, and I am trying to code a client bot for a game called Minecraft, Originally written in Java, there have been quite a few people who have made custom multi-player servers for this game, Primarily in C#, or in a language that i've never heard of, such as Pascal.I'm looking right now at sending this:

Packet ID: 0x00 (0) As Byte
Protocol Version: 0x07(7) As byte
Username: "umby25" As String

[code].....

"Byte cannot be converted to 1-Dimensional array of byte"

I don't understand why this whole thing would work in all of the other programming languages, but not Visual basic.I have tried converting the string using the same method that one of the open source C# servers used, and it failed, telling me that the dictionary does not contain that or something.

Converting Hex String To Byte Array?

Mar 8, 2011

I am working on a mini project that requires me to take a 8 byte hex string that I received from the Serial Port and convert it into a Byte Array and display it on the screen.An example of the string that I receive is 01050001FFFF8FFB

I am currently using the System.Text.ASCIIEncoding.ASCII.GetBytes(str) to help me achieve this. However I realised that if this does not support extended ASCII so whatever byte that is > 7F, I will not get the right value.My current code is as follows:

vb
Private Sub SerialPort1_DataReceived(ByVal sender As Object, ByVal e As System.IO.Ports.SerialDataReceivedEventArgs) Handles SerialPort1.DataReceived
Dim str As String

VS 2008 Converting This Byte Array To A String

Jun 9, 2010

I'm calling a Windows API that gives me a byte array which represents a unicode string - the problem is that if I call Text.Encoding.ASCII.Get String on it I just get the first letter of the string. The reason for this is that byte array has an empty byte between each character. I've verified that removing these empty bytes resolves the problem by just using a simple For loop to add the bytes that do have a value in into a new byte array, then calling Text.Encoding.ASCII.GetString on that and that gives me the full string I'm expecting.I'm just wondering if there is any easier way of getting the working string though without having to do a loop and create a new byte array etc?

Dim bCount As Long = 0
For Each item In TheString
b(bCount) = Asc(item)
bCount += 1

Atm I got this

a
Function readSignedByte() As SByte
'-128/127
Dim b As SByte

it doesn't work one that well works for numbers positive over 127 if lets say ReadByte() has 128 it would give overflow error which I don't want it to give I would like it to overflow the number to negivate value aka its signed value.

Display A Byte Other Than Its ASCII?

Feb 4, 2009

I read parameters from my ECU thru RS232 and display them on TextBox. But the display is ASCII instead of itself. E.g. I read 0x01 and store it in DataReceived, and set

Dim DataRecevied As Byte

TextBox1.Text = DataReceived

The value appeared in TextBox1 is 49 (0x31), which is ASCII of 0x01. How to display 01 there?

VS 2008 : Converting A "binary String" Into A Byte Or Char?

May 23, 2010

I've been trying to figure this out for hours now, and I've given up on trying to solve it myself. Basically what I need to do, is convert a "double octet" binary string, such as "11010011 01011101", into a byte or char type if possible.I use the following code to convert my Unicode text into binary:

Private Function ByteToStr(ByVal bt() As Byte) As String
Dim st As New StringBuilder
For Each byt As Byte In bt

[code]....

But that gives me weird results. The "Convert.FromBase64String" obviously isn't what I'm after. Any help would be great. If I can convert the "binary string" into a bytes or chars I can get it into a string.

Character Encoding - Converting UTF-8 To ASCII?

Feb 20, 2009

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.

Convert Byte Array Into A String Like So Dim Byt As Byte()?

Jan 25, 2011

I have a byte array that I convert into a string like so Dim byt As Byte() = New Byte(255) {} s = New String(Encoding.ASCII.GetChars(byte))My question is when I look at the string in a debuger its clearly a normal string but when I compare it to what I know its supposed to be it doesnt equal. So i did a quick check and for some reason its return a string thats the length of 256 characters. So i did a s.trim and it still is 256 characters long.

Communications :: Converting To Byte ?

Jun 28, 2010

I am sending data to some microchips with a serial port control using:

Code:

well, it work up to the value 9, but anything with more that one decimal place sends a byte value of the rightmost digit. So, 16 in the text box will send 6. Basically, it appears to be sending just 6, or 1 followed by 6. Is this how the serial port sends data...one digital at a time? Or, is the conversion to a byte failing?
