View 19 RepliesI 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 think I need a two dimensional byte array I currently have something like this:
Dim MbyteData(196608) As Byte
' Open the file that is to be loaded into a byte array
Dim oFile As System.IO.FileInfo
oFile = New System.IO.FileInfo(sFilePath)
[code]....
I now need to load several files at once (say four) so I need four arrays of 196608 bytes and I want to reference them by a number - 0 to 3, assuming the array is zero based. If I use Dim MbyteData(196608, 3) as byte or Dim MbyteData(3, 196608) as byte the syntax seems to be correct but I hit an error ("Number of indices is less than the number of dimensions of the indexed array") when I try to add the extra dimension to the stream read with something like oFileStream.Read(MbyteData(index), 0, MiByteCount).
I have used the following code to read a memory address from a pointer and offset previously however, Now I've come to use it again and can't figure out how I got it working last time, I'm receiving the error "value of type '1-dimensional array of Byte' cannot be converted to integer" highlighting the BytesAtAddress variable in the ReadProcessMemory calls.

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?

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

I 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
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

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?
