Convert An Integer Into A Byte Array?
Jun 15, 2010I am reading/writing a fixed length header into a stream and I need to do the following in VB:
1. Convert a 2 byte integer (int16) into a byte array
2. Read 2 bytes of a byte array into an integer variable
Convert Byte Array To 16 Bit Integer?
Aug 8, 2009I 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

but VB.NET Express 2008 gives me the error that Error 1 Value of type '1-dimensional array of Byte' cannot be converted to 'Short'.

Change Byte() To Structs For Readability And Convert Struct To Byte Stream For Socket Send()
Dec 8, 2009I 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?

View 19 RepliesConvert Byte Array Into A String Like So Dim Byt As Byte()?
Jan 25, 2011I 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.

View 19 RepliesByte Array To Integer With Bitconverter?
Dec 27, 2011I am new to vb net so please cut me some slack if this is a stupid question, I have always used vb6 before, but finding that its less and less supported so trying to learn vb.net by myself. Also I am doing this for a hobby not a profession.I am writing an Console application to read a file sequentially 1 byte at a time into a 1 byte buffer. It then copies that byte into a 4 byte lookup buffer, that moves, ie as the file pointer moves forward by one byte the 4 byte lookup buffer copies the last 3 bytes into the first 3 bytes to accept the byte at the file pointer into the 4th byte of the lookup buffer. I am doing 1 byte at a time because the data I am looking for is not at pre-determind offsets and filesizes may not be a multiple of 4.
[Code]...
Help please its driving me mad It appears as if the byte is not being transferred to the lookup buffer so that it would always be 0, either that or I am not converting it to an integer properly

C# - How To Properly Read 16 Byte Unsigned Integer With BinaryReader
Jun 9, 2010I need to parse a binary stream in .NET to convert a 16 byte unsigned integer. I would like to use the BinaryReader.ReadUIntXX() functions but there isn't a BinaryReader.ReadUInt128() function available.

View 3 RepliesDoes BeginSendTo Prefix A Message With A 4 Byte Integer Of The Size
Dec 16, 2010I inherited a project that includes a dialog between two applications. One in native C++ the other in VB.NET. The protocol is such that the first 4 bytes (32 bits) of the message encodes the size. However the VB.NET side never sets these first four bytes, however it does use the .net method BeginSendTo, which accepts an argument for size. Does the BeginSendTo method automatically add the size to the beginning of the message in the form of a 4 byte int?

View 6 RepliesConvert Char To Byte?
Jan 25, 2010My 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.
