.net - Find Location Of A Short Sequence Of Bytes In Byte Array?

Jan 15, 2011

How can I efficiently find the location of the first instance of a four byte sequence within a byte array? Is there something more efficient than looping through the whole array, or a built-in method?

I'm searching through a byte array for a pair of CrLF. I can't convert it to string for an InStr first because I need the position of it in the original byte array.

I am trying to figure out the location of this, as it delimits between a string portion and a binary portion, similar (well, exactly like for this part of it) to an HTTP header. There is a string portion, and two CrLf before the content begins.

Change Byte() To Structs For Readability And Convert Struct To Byte Stream For Socket Send()

Dec 8, 2009

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?

Truncating Data Types From Int To Byte, Transferring 8 LSBs To The Byte?

May 16, 2011

Is it possible in VB to truncate a larger data type ( an int with a value greater than 255) to a smaller one, say a Byte (which only goes up to 255) in a way such that the 8LSBs of the integer are copied to the newly created byte. I have tried this using CType with the following code, however it does not work.

Dim TestByte As Byte = CType(Test, Byte)
Where the variable "Test" is an integer with a value of 419. This code always results in the Overflow exception.

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 would like to know how to convert a unisgned byte to signed byte

Atm I got this

a
Function readSignedByte() As SByte
'-128/127
Dim b As SByte

[Code]....

it doesn't work one that well works for numbers positive over 127 if lets say ReadByte() has 128 it would give overflow error which I don't want it to give I would like it to overflow the number to negivate value aka its signed value.

Getting An Invalid "Invalid Length For A Base-64 Char Array"?

Sep 9, 2011

where I was encrypting the string and passing it to another web page to decrypt and get the ids to be displayed as a pdf back to the page. I kept getting an invalid "Invalid length for a Base-64 char array". It was then I realised that the string was getting truncated and that the IE Explorer had a size limit for the number of charaters being passes as a querystring.So I think I need to go the route of posting it.But not sure how to go about it.

Private Sub GetReport()
Try
Dim hawbs As String = String.Empty[code]....

The retrieve document then does: the decrpytion gets the data(ids) and pulls the pdfs.
