I have a problem using FJ Core to convert image into byte.

I have a code written in C# which works fine.

The problem is when im running it in VB i get the exception: Arithmetic operation resulted in an overflow

It works fine in C# to convert a negative number into byte For Ex. (byte)-90024 = 88

But when i try to do it in VB i get the exception.[code]...

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?


Imports System.ComponentModel
Imports System.Text

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.

Convert Char To Byte?

Jan 25, 2010

My application is reading in data from the serial port. The packet format uses 1 byte to tell the data length. The problem is as I am reading each byte in as a char when I try to get the value of the received character (using Asc(cRxd)) it only works up to values of 127, any bytes received that are over 127 are received as 63. I noticed that this was the default parity replace value, but I have parity.none set and I also changed the parity replace value. The received byte is always 63. I have tried reading the data using .ReadByte but this gives the same result - only works on values below 128.

How To Convert This Byte Array

Oct 19, 2011

Ok, I am tasked with changing certain text labels that exist within 1000's of CAD files. The only way to change the text labels, as of now, is to open each CAD file in a CAD editor, change the labels by hand, and save it as a new file name, and that will take forever.So, I want to make this job easier and to do that I need to write a program to do it automatically (not a Macro). So far, I have made an app that loads the CAD file's bytes, finds the position of the label's text bytes, and replaces the text bytes with my own bytes, and saves the file under a new name.The problem is, I don't know the format/encoding/whatever they used to write the string to bytes..... The good thing is, I have unlimited examples to learn from because I can use the CAD program to change the text and then see the results in Hex. I want MY program to mimic the results.Here is some hex examples;

13 BE FD F9 00 = wood
0F 1E 1E 80 = cat
0F 26 FC E0 = dog

C# - Convert List(of Byte) To Picturebox

May 19, 2010

I have a jpeg file that is being held as a list(of Byte). Currently I have code that I can use to load and save the jpeg file as either a binary (.jpeg) or a csv of bytes (asadsda.csv). I would like to be able to take the list(of Byte) and convert it directly to a Picturebox without saving it to disk and then loading it to the picturebox. If you are curious, the reason I get the picture file as a list of bytes is because it gets transfered over serial via an industrial byte oriented protocol as just a bunch of bytes. I am using VB.net, but C# example is fine too.

Convert .EXE File Into Byte And Back Again ?

Sep 2, 2010

Basically what I'm now trying to find out is simply how to convert an Executable file into byte or byte array as i've heard it called, and then back again. I had a friend used to do it with a program in VB6 a few years ago where he would convert the EXE into byte and store it in a sql database and then his boss would be able to retrieve it later on when he was out on business overseas and it seemed to work very well.I'd like to know how to do it in VB.NET, however after going through some sites using google search I have come up short.

Convert Byte Array To 16 Bit Integer?

Aug 8, 2009

I have a very simple question about converting a byte array into 16bit integers. I am connected to a device through a serial port. It sent me six bytes which represent three Int16 integers. For example, the byte array is called newRecievedData(5) and has a length of 6.

The manual that came with the device claims that the int Format is 8 bit MSB|8 bit LSB. Does that mean the following?

newRecievedData(0) contains 8 high bits of the first Int16
newRecievedData(1) contains 8 low bits of the first Int16
newRecievedData(2) contains 8 high bits of the second Int16

Convert Byte Array To Hex String?

Aug 12, 2009

I have an activex control that outputs a template object to the client, which gets serialized to a byte array. My attempts to put this byte array in a hidden field for post back to the server have given mixed reults, in that the size of the byte array decreases when sent to the server. My best guess is that the byte array is being truncated when put into a (string) hidden field.

I convert the byte array to a HEX string on the client side before passing over to the server, then converting it back on the server - HEX to byte array. If found some examples of how to do this in C#, VB.net but I haven't a clue how to accomplish this on the client - vbscript, javascript, etc,

I'm guessing something like this would get it done on the server, but how would I accomplish this on the client side?

Private Function Bytes_To_String2(ByVal bytes_Input As Byte()) As String
Dim strTemp As New StringBuilder(bytes_Input.Length * 2)
For Each b As Byte In bytes_Input

Convert Byte-array To Object?

in my project I use an Excel workbook as template. Right now, this workbook is located in the same directory as the exe-assembly and can be opened and manipulated by the user. To avoid this, I thought about adding the workbook to a ressource. That works. Problem: how can I convert the resulting byte-array/stream back to a workbook-object?I tried like this, but - obviously - the conversion fails:

Dim wkb As Excel.Workbook
