Converting File Into Bytes And Then Converting Those Files Back Into Its Original Form?

my goal is to

1.Take an file(exe,dll,etc)

2.Convert it into hex

3.place that hex values in a stack

4.Execute the values inside the stack to its original form(i.e. take the elements out of stack and then convert it to a compile format)

Imports System.IO
Sub Main()
Dim fileName As String = "ABC.exe"

Converting Bytes To Another Format

Jan 20, 2011

I 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, 2011

I'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, 2010

I 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

Converting String To Bytes And Viceversa?

Feb 18, 2011

Ive 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, 2011

This 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?

Converting The Bytes() To A Readable Text?

Oct 6, 2010

I 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.

Serial Communication - Converting To Bytes

Dec 1, 2011

I 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.

Conversion - Converting Bytes To A Signed Integer

Nov 29, 2009

I 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]

Converting Bytes To IEEE Float And Vice Versa?

Dec 6, 2009

I 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.

I want it to do is that you input a string, then you select an algorithm (Theres only going to be one RijnDael) then you input a key, then the Initialization Vector comes from "txtIV.text" then you select the key bytes and the block bytes from the numeric up/down, then you either encrypt or decrypt.

VS 2008 What Does This Line Exactly Do - I = Stream.Read(bytes, 0, Bytes.Length)

Dec 28, 2010

What 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)
While (i <> 0)
Try
' Translate data bytes to a ASCII string.

Able To Add The Bytes To Get 256?

Feb 21, 2010

I am not sure how to explain but will try through example. I need to be able to add bits to a byte see below.

I have a total of four bytes (256mb). I need to be able to add the bytes to get 256?

Example: Byte1 = 0 Byte2 = 0 byte3 = 108 byte4 = 1 I need this to equal 217 (11011001) 108 (1101100) + 1(1) = 217(11011001)

C# - Get The Bytes From A Stream?

Jun 4, 2012

I'm writing a VB.net application (but you can answer in C# if you want, no problem) that uses a 3rd party .NET library. In particular, one method in this library takes an IO.Stream as input (among other things) and writes the results of its processing to said stream. My problem is that the method CLOSES the stream after writing to it, so I can't read back the data that it wrote in it!To be more specific: it works, of course, if the stream is a FIeStream , since it writes the data on disk, but what if I want to read the data directly to memory? I tried using a MemoryStream, but as I said, when the method returns the stream is already closed, and I can't read back anything from it.

Imports System.IO
Public Class CloseHijackedMemoryStream
Inherits MemoryStream

Get The CRC Of Array Of Bytes?

I have a simple problem (I think). I would like to get the CRC of this array of bytes

0x0 0x7E or 0 7E or 0

Anyway the one calculator I use gives me: 78F0 or 78 F0 (Hex). Anyway, I think its CRC16 but im not sure. So if anyway can show me some code to give me a CRC calculation that matches (78 F0 or 78F0), that would be great, Im not sure if you have to include 7E or not

How To Convert Bytes To KB / MB Or GB

My app displays the bytes downloaded in a label using:
Private Sub MyDownloader_DownloadedByteCountChanged(ByVal ByteCount As Integer) Handles MyDownloader.DownloadedByteCountChanged
lblDownloaded.Text = ByteCount.ToString()

But I thought it would be 'nicer' if it display the amount as kb/mb/gb, etc.

.net - Convert A Single Into 8 Bytes?

Jan 6, 2010

I have a single that might have a decimal place but might not. I have to put the digit before the decimal into the first 4 bytes and the digit after in the next 4 bytes.

So 1.1 would be 01-00-00-00-01-00-00-00
or 2.1 would be 02-00-00-00-01-00-00-00
or 1 would be 01-00-00-00-00-00-00-00

The digit before the decimal point is stored like an integer in bytes the same with the digit after the point. So 1.1 gets split into 1 and 1 and then stored as 2 DWORDS: 01000000 and 01000000
