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.

I 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?
Private Function Bytes_To_String2(ByVal bytes_Input As Byte()) As String
Dim strTemp As New StringBuilder(bytes_Input.Length * 2)
For Each b As Byte In bytes_Input

I m using encryption and decryption
When I use Return Convert.ToBase64String(ms.ToArray()), I can decrypt data by first Convert.FromBase64String(stringToDecrypt) and it works fine.
But if I dont use Base64string method when returning the data and use .Encoding.ASCII.GetString(ms.ToArray) and then try to decrypt, I get "Bad data" error

I'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
Socket.BeginSend(ByVal buffer() As Byte buildpacket()
Below is taking a struct (listed at bottom) as an argument and building a string using eg. Chr().
How can I convert the output of buildpacket(), eg. "yyyypyu" into a Byte().
Public Function buildpacket(ByVal packet As PacketRecord) As String
Dim temppacket As String
Dim checksum, i As Integer
'Build packet to Transmit
temppacket = Chr(255) & Chr(255) & Chr(255) & Chr(255) & Chr(254)

Failure reasons: I am getting the output as some symbols, prob because the server is not able to read the format of the word content.how to read the word document data in binary data to a string.

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?

I'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

I 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
1. morph byte arrays 'ToSocket' and 'ToMTP' below into structs and
2. convert into byte array for Socket.BeginSend(byte(),.....) to stream out to remote devices?

Ok, I am tasked with changing certain text labels that exist within 1000's of CAD files. The only way to change the text labels, as of now, is to open each CAD file in a CAD editor, change the labels by hand, and save it as a new file name, and that will take forever.So, I want to make this job easier and to do that I need to write a program to do it automatically (not a Macro). So far, I have made an app that loads the CAD file's bytes, finds the position of the label's text bytes, and replaces the text bytes with my own bytes, and saves the file under a new name.The problem is, I don't know the format/encoding/whatever they used to write the string to bytes..... The good thing is, I have unlimited examples to learn from because I can use the CAD program to change the text and then see the results in Hex. I want MY program to mimic the results.Here is some hex examples;
13 BE FD F9 00 = wood
0F 1E 1E 80 = cat
0F 26 FC E0 = dog

I have a very simple question about converting a byte array into 16bit integers. I am connected to a device through a serial port. It sent me six bytes which represent three Int16 integers. For example, the byte array is called newRecievedData(5) and has a length of 6.
The manual that came with the device claims that the int Format is 8 bit MSB|8 bit LSB. Does that mean the following?
newRecievedData(0) contains 8 high bits of the first Int16
newRecievedData(1) contains 8 low bits of the first Int16
newRecievedData(2) contains 8 high bits of the second Int16
[Code]....
but VB.NET Express 2008 gives me the error that Error 1 Value of type '1-dimensional array of Byte' cannot be converted to 'Short'.
