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.

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?

Now m trying to convert this to C#, but im a little confused as to exactly the meaning of this line:

If lbytRelayStateMask And (2 ^ lintCounter) Then It appears there something going on behind the scenes (that ill have to examine further) however before i do i would just like to clarify the result of this if statement. Am i correct in saying if either one of the sub-expressions equals zero then its false, otherwise its true? Sorry, im not too up to speed on VB.net.

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.

Converting Unsigned Byte To Signed Byte?

May 6, 2007

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.

C# - Conversion From VB6 String Data To .NET Byte Array

May 7, 2009

I'm writing a C# application that reads data from an SQL database generated by VB6 code. The data is an array of Singles. I'm trying to convert them to a float[]

Below is the VB6 code that wrote the data in the database (cannot change this code):

Set fso = New FileSystemObject
strFilePath = "c: emp emp.tmp"
' Output the data to a temporary file

[Code]....

The problem here is the VB6 binary to string conversion. The VB6 string char is 2 bytes wide and I don't know how to transform this back to a binary format I can handle.

Below is a dump of the temp file that the VB6 code generates:

And here is the dump of the data as I read it from the database in (=the VB6 string):
