concatenate long and bytearray to another bytearray
Category : Programming Languages

I am trying to concatenate long and bytearray to another bytearray.


I tried like this :


byte[] value1= new byte[16];
byte[] value2= new byte[16];
byte[] finalvalue = new byte[value1.length + value2.length];
long ts = System.currentTimeMillis();
int val = 100;
ByteBuffer.wrap(value1).order(ByteOrder.LITTLE_ENDIAN).asLongBuffer().put(ts);

C to C# Bytearray + hex
Category : C & C++ & C#

I'm currently trying to get this C code converted into C#.
Since I'm not really familiar with C I'd really apprecheate your help!


static unsigned char byte_table[2080] = {0};

First of, some bytearray gets declared but never filled which I'm okay with


BYTE* packet = //bytes come in here from a file
int unknownVal = 0;

Bit manipulation from a ByteArray
Category : Programming Languages

I would like to know how to manipulate bits from a ByteArray.
What I need is to shift the bits according to a 'table' that I have.


Table:


Bit 0 -> Bit 26
Bit 1 -> Bit 31
Bit 2 -> Bit 17
...
Bit 31 -> Bit 5

I convert the ByteArray to BitArray using this method


public static BitArray ByteArraytoBit

GUID to ByteArray
Category : Programming Languages

I just wrote this code to convert a GUID into a byte array. Can anyone shoot any holes in it or suggest something better?


public static byte[] getGuidAsByteArray(){
UUID uuid = UUID.randomUUID();
long longOne = uuid.getMostSignificantBits();
long longTwo = uuid.getLeastSignificantBits();
return new byte[] {
(byte)(longOne >>> 56),

How do I get an IL bytearray from a DynamicMethod?
Category : Programming Languages

As a bit of a novelty, I'm trying to see how different the IL from light weight code generated at runtime looks vs code generated by the VS compiler, as I noticed that VS code tends to run with a different performance profile for things like casts.


So I wrote the following code::


Func<object,string> vs = x=>(string)x;
Expression<Func<object,string&

endarray : array of byte;
hFile : THandle;

dwRead : DWORD;

MD5 ByteArray Different between AS3 and Java
Category : Java

I'm trying to port a library from Java into AS3, and I'm down to the MD5 function. I'm using the MD5 library found as part of the project here: http://code.google.com/p/as3crypto/.


I'm getting the length correct, and about half of the values are correct. The ironic thing is the correct values are in the correct spot as well. Only the negative values are wrong. As an example, the two
