Which I want to convert to a byte array. Is there a built in function in .NET 3.5 that will get the job done or will I need to write a function to loop through each pair in the string and convert it to its 8-bit integer equivalent?
This program, it reads in a file, and displays it in hexadecimal, like using a hex editor. It then goes to compare the strings and whatnot, and display certain values. During the program, there is a time where I need to display a set of offsets as decimal because that is the way that it is shown regularly.
Taking the two specific offsets and displaying them in hex ends up giving me something like "3039" or "000A", which should respectively convert to 12345 or 00010. This "ID" that I am converting, can be 00000 to 65535, which in hex is 0000 to FFFF. The current method I was given only works if the value is less than 512 or something like that.

I would like to covert a 4 digit hexadecimal code point to UTF8.

View 2 RepliesI am trying to reference the KeyDown event from a independent sub procedure and have it loop back into original independent sub procedure. Starts off in Independent sub procedure (DisplayAction - which then calls KeyDown Event) Goes into KeyDown event (KeyDown then calls DisplayAction) Goes back into original sub procedure (DisplayAction) and the loop continues. * Steps 1 and 2 work just fine in my code. Step 3 is the problem. My program does not loop back into the independent sub procedure.

View 2 RepliesIs there anyway you can send information back to the original creator of the program? Here is a quick example- I made a little program that gives you general information about your computer, when you click a button it sets the text box to specific information. One of the text boxes gives you the Version of your OS. I would like to know if there is a way to send the information in that text box back to me when someone clicks it and they are connected to the internet. FYI I would tell the person who clicks it before so that I am not stealing information, plus what is there to steal from a simple program I made.

I'm trying to convert a large array to a string, and then back into the array again after sending it over a network connection. No problems with that, but to keep my string as small as possible, I want to convert each array element into a single byte. I know that each element is going to contain a number no bigger than 100, so there will be no problems keeping them all 1 byte long. Problem is, I can't find the correct conversion commands. I think I should use 'Chr' to convert them into a string, but I can't work out how to convert that back into a number at the other end.
View 3 RepliesI've got the following simple code to convert Bytes to a Hex string :-
Code:
Shared Function BytesToHex(ByVal bytes() As Byte) As String
If bytes Is Nothing Then Return ""
Dim S As String = BitConverter.ToString(bytes)
[Code].....
The HexToBytes routine obviously can take a lot longer to complete than the BytesToHex routine and is noticeably slower when dealing with a lot of data. As I'm converting a lot of hex strings back to bytes, I wondered if there was a more efficient way of doing it without looping through the whole string as I am doing?
