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?

Converting Hex String To Byte Array?
Mar 8, 2011I 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

How To Convert String To Byte Array
Dec 8, 2009I'm trying to figure out how to convert a string inot a byte array to send as a packet over a socket. Initially it was used for serialport.write but I would like to use in

How can I convert the output of buildpacket(), eg. "yyyypyu" into a Byte().

Read Byte Array To String
Sep 20, 2011I'm trying to read a byte array into a string however it's array is filling up from a dll in the following format. [Code] now its decoding the first byte but I think because of the next [0] it's not completing the whole array. This is the code that I'm using:
Radiotext = System.Text.Encoding.ASCII.GetString(szRetRDS)
I did think about writing it into another byte array excluding the [0] but unsure how I would go about this.
C# - Conversion From VB6 String Data To .NET Byte Array
May 7, 2009I'm writing a C# application that reads data from an SQL database generated by VB6 code. The data is an array of Singles. I'm trying to convert them to a float[]
Below is the VB6 code that wrote the data in the database (cannot change this code):
Set fso = New FileSystemObject
strFilePath = "c: emp emp.tmp"
' Output the data to a temporary file
[Code]....
The problem here is the VB6 binary to string conversion. The VB6 string char is 2 bytes wide and I don't know how to transform this back to a binary format I can handle.
Below is a dump of the temp file that the VB6 code generates:
And here is the dump of the data as I read it from the database in (=the VB6 string):

VS 2008 Converting This Byte Array To A String
Jun 9, 2010I'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?

VS 2010 Extract String From Byte Array Or Memorystream?

I need to check this data to see if there's a certain url and then extract it.
The url I need to find looks like this:http://201.122.38.5/data/today/798572987-589571?139805890582 The length of the 'code' after "/today/" is always the same. The IP address changes. What's the best/fastest/most efficient way to continuously check these byte arrays or memorystreams and extract the urls without hogging the CPU too much?
