I recently had a discussion with a colleague about serialization of byte data over a network. He used the BinaryFormatter class to "unparse" the byte data I was sending to him. This did not work and he obviously had exceptional... exceptions. Binaryformatter could not "unparse" the data correctly since my data was simply a byte array. H...
I am trying to display the images in my Asp.Net MVC 1.0 application. I can successfully get the Image (into byte[]) from DB. How can I display it into the <img>? ...
My current situation is I have to read in a file and place it in an InputStream, and then also place the contents of the InputStreaminto a byte array which requires that i know the size of the InputStream. Any ideas? As requested, i will show the input stream that i am creating from an uploaded file InputStream uploadedStream = null; ...
Hi, I need to convert pdf to byte array and vice versa. Can any one help me? This is how I am converting to byte array public static byte[] convertDocToByteArray(String sourcePath) { byte[] byteArray=null; try { InputStream inputStream = new FileInputStream(sourcePath); String i...
I don't really care about encoding and stuff, as long as I get back the exact same byte array. So to sum up: How do I convert a byte array into a string, and then that string back into the same byte array I started with? ...
Thanks to everyone in advance. I'd like to access the nth byte of a binary scalar. For example you could get all the file data in one scalar variable... Imagine that the binary data is collected into scalar... open(SOURCE, "<", "wl.jpg"); my $thisByteData = undef; while(<SOURCE>){$thisByteData .= $_;} close SOURCE; $thisByteData...
I'm trying to create a function (C#) that will take 2 integers (a value to become a byte[], a value to set the length of the array to) and return a byte[] representing the value. Right now, I have a function which only returns byte[]s of a length of 4 (I'm presuming 32-bit). For instance, something like InttoByteArray(0x01, 2) should r...
I currently have a function [C#] which takes a byte[] and an alignment to set it to, but during encryption, an error is thrown every once in awhile. private byte[] AlignByteArray(byte[] content, int alignto) { long thelength = content.Length - 1; long remainder = 1; while (remainder != 0) { ...
Related Question In the related question, I was trying to figure out the fastest way. The method I chose in that question has become a bottle neck for me. I am reading some binary data from a file and need to put it into a managed structure definition. No unmanaged code is involved so I'm thinking there is a better way than allocating t...
I am doing RSA encryption and I have to split my long string into small byte[] and encrypt them. I then combine the arrays and convert to string and write to a secure file. Then encryption creates byte[128] I use this the following to combine: public static byte[] Combine(params byte[][] arrays) { byte[] ret = new byte[arrays.Sum(...
I'm doing a simple test. I want to write BitmapData into a ByteArray. I'm trying to do this with writeObject() and readObject(). Read object seems to have trouble making sense of the BitmapData. var byteArray : ByteArray = new ByteArray(); var _cache : BitmapData = new BitmapData( 640, 480, true, 0x000000 ); var _blank : BitmapData = ne...

How do I create a System.Windows.Media.ImageSource from a byte array? I have a byte array, containing the exact and complete file contents of a TIFF image file. I need to display this on the screen, and I have no idea where to even start. Supposedly, it can be done (according to my boss, our dev team has done it in the past, but no...
Hi, I'm trying to get my website to allow users to upload various files (HttpPostedFile), which are then stored in an Oracle database as BLOBs. Here's what I've got so far: public static bool insertFile(int pid, HttpPostedFile file, string filedesc) { string filename = file.FileName.Remove(0, file.FileName.LastIndexOf("\...
I am having some sort of problem with encoding in my ASP.NET HTTPHandler, which uploads a file. The file content is passed in a hidden form variable from a ColdFusion web page which is using something called "ToBase64". In ColdFusion, the code used to place the file content into a form is as follows: <cffile action="readBinary" file="#...
As you may have figured out from the title, I'm having problems converting QByteArray to an integer. QByteArray buffer = server->read(8192); QByteArray q_size = buffer.mid(0, 2); int size = q_size.toInt(); However, size is 0. The buffer doesn't receive any ASCII character and I believe the toInt() function won't work if it's not an...
I have the following code in VB.net Dim bytIV() As Byte = {121, 241, 10, 1, 132, 74, 11, 39, 255, 91, 45, 78, 14, 211, 22, 62} I'm trying to convert it to php. $iv = array(121, 241, 10, 1, 132, 74, 11, 39, 255, 91, 45, 78, 14, 211, 22, 62); That doesn't work.

I want to store a byte array wrapped in a String object. Here's the scenario The user enters a password. The bytes of that password are obtained using the getBytes() String method. They bytes are encrypted using java's crypo package. Those bytes are then converted into a String using the constructor new String(bytes[]) That String is ...
