Convert Byte Array Into A String Like So Dim Byt As Byte()?
Jan 25, 2011I 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.

Convert Byte Array To Hex String?
Aug 12, 2009I have an activex control that outputs a template object to the client, which gets serialized to a byte array. My attempts to put this byte array in a hidden field for post back to the server have given mixed reults, in that the size of the byte array decreases when sent to the server. My best guess is that the byte array is being truncated when put into a (string) hidden field.
I convert the byte array to a HEX string on the client side before passing over to the server, then converting it back on the server - HEX to byte array. If found some examples of how to do this in C#, VB.net but I haven't a clue how to accomplish this on the client - vbscript, javascript, etc,
I'm guessing something like this would get it done on the server, but how would I accomplish this on the client side?

Convert A Byte Stream To A Text String?
Mar 31, 2011I'm working on a licensing system for my application. I'd like to put all licensing information (licensee name, expiration date, and enabled features) into an object, encrypt that object with a private key, then represent the encrypted data as a single text string which I can send via email to my customers.
I've managed to get the encrypted data into a byte stream, but I don't know how to convert that byte stream into a text value -- something that contains no control characters or whitespace. Can anyone offer advice on how to do that? I've been researching the Encoding class, but I can't find a text-only encoding.

Convert String Containing Upper ASCII Characters To Byte Array?
Oct 9, 2008How 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?

Convert A Byte Array From Socket Into A String To Replicate - How The Serial Port Receives Data
Sep 21, 2010I've inherited a tested function that processes incoming data from a .NET Serial Port. (Dim RXBuffer as string = serialport1.ReadExisting) I've written a different part of the application that processes a byte array as received from an asynchronous .NET socket.
Is there a way I can convert the byte array into a string as if it arrived from the serial port?
I would prefer to rewrite a very long 'if statement' into byte array functions syntax that look like:
dim b as boolean = IsBitSet(state_buffer(i), j) 'rather than:
dim b as boolean = (Asc(Mid(RXPacket.Pdu, CInt((i - (i Mod 8)) / 8) + 1, 1)) And CInt(2 ^ (i Mod 8))) > 0
Change Byte() To Structs For Readability And Convert Struct To Byte Stream For Socket Send()
Dec 8, 2009I just converted the following code from c# to vb.net. It is functional and works correctly with my company's firmware/devices. My next challenge. Previous serialport code used much more readable structs which where then converted (after building a packet) into byte() automatically as part of the serialport encoding. (this is my understanding)How could I

2. convert into byte array for Socket.BeginSend(byte(),.....) to stream out to remote devices?

Byte Conversion To Single Number
Aug 4, 2010I am totally new with VB.NET. I have started coding for Modbus protocol. The response that I receive from the slave is as below -
01 = byte slave id
03 = byte function code
04 = byte -no. of bytes sent by slave
00 = byte(8 bits) (Lower Register MSB)
00 = byte(8 bits) (Lower Register LSB)
64 = byte(8 bits) (Upper Register MSB)
00 = byte(8 bits) (Upper Register LSB)
2bytes for crc
Now I want the value of 64 00 00 00 into floating point number in Vb.net . I think in vb.net its single as its 32bit floating precision number. Now the bytes that I need are 00 64 00 00 but if i process in this way the output is different, so I tried manually putting the data into the byte array and found out that I need 64 00 00 00 to be processed so that i can get desired output.
Takes A Single Byte As An Argument?
Dec 4, 2009Ok, this is going to be a bit bizarre, but I'm looking for something strange, so all suggestions are welcome:I have a function that takes a single byte as an argument. From that byte, without using any random function, I need to create two other random bytes. I specifically cannot use the Random object, but fortunately, the other bytes do not need to be random relative to the argument. Also, the argument is random.
Therefore, one other byte can be created by XORing with &HFF, which will create the inverse of the argument. Since the argument is random, the inverse is also random. I need one other technique that will create that last pseudo-random byte. I thought about bit shifting, but that results in something quite a bit less than random (it will be biased high or low, depending on the bit shifting).
One possibility that I am trying is to use CByte(100000/arg). Does anybody have any other suggestions?
EDIT: The result of that equation for all values of the argument is a very interesting pattern. It will probably be fine, but I'd still take suggestions.
Getting And Setting Single Bits In A Byte-array Using .net?
Jul 5, 2011I have a byte array with 512 Elements and need to get and set a single bit of a byte in this array.The operation must not change any other bits, only the specified one.So if I have a byte like &B00110011 and would like to change the third bit to 1 it should be &B00110111.
Like this:Dim myarray(511) as byte myarray(3).2 = 1 ---> This would change the third bit (start counting at 0) of the third byte to 1 I know it should be easily possible using bit-masking but I don't have the time to try for days to get it working.
