Converting The Bytes() To A Readable Text?
Oct 6, 2010I am having trouble converting the Bytes() to a readable text.
I will be receiving packets from a UDP Connection, but due to lack of connectivity issues, they have provided me a .mem file that i am assuming is the whole stream of the packet.
So for now, i am trying to read the file and i get a collection of bytes(). but i cannot convert it to readable text.

View 11 RepliesConverting Bytes To Another Format
Jan 20, 2011I have been looking for a way to convert bytes down into another unit and append the unit format to the end and return it. I have found a few posts about it but I didn't perticularly want to write that much code that they listed, so I designed "my own" (I'm sure I'm not the only one who has done this method).Since I am pretty new at all this, I was wondering if anyone could let me know if there are any problems with how it would process the information and perhaps make it faster.[code]

Converting Hex In A String Back To Bytes?
Jun 9, 2011I've got the following simple code to convert Bytes to a Hex string :-
Code:
Shared Function BytesToHex(ByVal bytes() As Byte) As String
If bytes Is Nothing Then Return ""
Dim S As String = BitConverter.ToString(bytes)
[Code].....
The HexToBytes routine obviously can take a lot longer to complete than the BytesToHex routine and is noticeably slower when dealing with a lot of data. As I'm converting a lot of hex strings back to bytes, I wondered if there was a more efficient way of doing it without looping through the whole string as I am doing?
Converting Singles/Doubles To 8 Bytes?
Jun 13, 2010I am tasked with the job of reading the X and Y coordinate of a Text label from a "save file" of a 2D CAD drawing. I found the exact position of the coordinates in the file, but I still don't understand how to read them 100%. They aren't simple ASCII characters.First, I read the file byte by byte, and load them into a textbox seperated by spaces as numbers from 0 to 255. Here is an example X and Y coordinate
View 1 RepliesConverting String To Bytes And Viceversa?
Feb 18, 2011Ive 2 buttons and 3 text boxes.Button 1 encrypts the data from textbox1 to bytes, converts it to string and display it in textbox2.Button 2 reads string from textbox2, converts it to bytes and decrypts it displaying it in textbox3 (textbox1 and 3 got to match).The encrypt/decrypt process works fine but the conversion from string to bytes is failing and cannot seem to find the problem. The error states that the string doesnt have the same format (Bytes(i) = Byte.Parse(Values(i))

Converting String To List Of Bytes?
Jun 2, 2011This has to be incredibly simple, but I must not be looking in the right place.
I'm receiving this string via a FTDI usb connection:
'UUU'
I would like to receive this as a byte array of
[85,85,85]
In Python, this I would convert a string to a byte array like this: [ord(c) for c in 'UUU']
I've looked around, but haven't figured this out. How do I do this in Visual Basic?
Serial Communication - Converting To Bytes
Dec 1, 2011I want to take a number such as 600 (0x0258) and send these hex values to a C-based system which is assigning char's to the received bytes and rebuilding to the original number. Currently, I am converting to bytes in VB.Net but it is not giving me the expected outcome (because of the ascii nature of the transfer most likely) [Code] I've also tried using Hex but this doesn't get the data in the correct format.
View 5 RepliesConversion - Converting Bytes To A Signed Integer
Nov 29, 2009I have query that involves a cross-language operation, namely converting 4 SBytes to a signed integer. The source language for this operation is Java, which utilizes the ByteBuffer in order to extract a signed integer from the data stream. The inner workings of ByteBuffer are at best a black box to me, as I haven't been able to find any hints to what actually goes on when Java extracts the integer. [Code]
View 2 RepliesConverting Bytes To IEEE Float And Vice Versa?
Dec 6, 2009I am reading and writing binary data through a serial port and must (a) reassemble the incoming four bytes that make up a IEEE single-precision float into an actual float, and (b) disassemble a float into its four constituent bytes before squirting them through the serial port.
I am using VB.NET 2008. In VB6, I could use the LSET command, as in:
Code:
Private Type typByteArray
B(1 To 4) As Byte
End Type
[Code]....
But of course this code won't work in VB.NET. In C it would be easy to handle situations like this by using unions, but VB.NET doesn't support them.

Dec 28, 2010What exactly does this line do?
i = stream.Read(bytes, 0, bytes.Length)
Does it read the entire message string sent by the client? I have a line to write to the stream later in the code and that does not seem to be sending anything back to the client, although the code around is excuting.
i = stream.Read(bytes, 0, bytes.Length)

View 6 RepliesConvert Bytes To XML Legal Text?
Aug 8, 2011I have to store the bytes of a image file inside of an XML file that is read by another program... The problem is, if I inject it as just plain bytes, the end-program has an error (presumably because it contains non-legal XML characters). How can I convert bytes into something that XML can legally read? I really have no other options at this point. I have to inject the image file as bytes (specifically a .bmp file).
