I have a StringArray that is filled with line of text and I need to take each array of strings and convert them to byte. How
Dim splitText() As String = TextRead.Split(Chr(13))
Dim byteArray() as string = Byte.Parse(splitText(0))
once I can get one element of the string array to convert to Byte I will put a loop around it for each position in the string array but it says the string format is not correct for the byte.parser.
I've been up for nearly 24 hours now. Trying to program an application for a game I have been playing.I've run in to a problem, I'm not sure how to solve.I have basic knowledge when it comes to VB (college class) so bare with me.[code]My only Idea would be loops to figure out where each of the edited numbers are in the array, But I was looking for something simple.Also, would it be easier to work with the bytes rather than edit them in string form?

I got a form and a checkbox with default names. In the form1 load event, I need to check the binary data of a registry key.
If data is 00 00 00 00 the checkbox will display a check mark
If data is 1b 00 00 00 the checkbox will shows nothing
Here is my code
Private Sub Form1_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
Dim b() As Byte = {0, 0, 0, 0}
Dim a() As Byte = My.Computer.Registry.GetValue("HKEY_CURRENT_USERSoftware", "Test",String.Empty)

I am transmitting data over an IP socket and receiving the data via a second program I have written. The server was in VB6 and am now creating a new one in vb.net to run as a service. The major issue I am having is related to the encoding features.
Issue 1 to be able to correctly encode a bytearray so that when it is received by a VB6 program via winsock that the data will be in the proper ANSI format for the pc to read it correctly. So far this works on some files and not on others depending on the content of the file.
Issue 2 to be able to correctly encode a bytearray, send it to a vb.net host program and correctly [decode?] write it to disk.
To make things a little more complicated I must also be able to do this where the client resides on a Windows Mobile, Windows CE, or Windows PC. I have been running some tests and have gotten mixed results.

I am in a rather silly situation...suppose I have a text box in which I enter a line of text/characters/numbers...how would I be able to display the last two or first two (or may be middle two?) characters into another text box.
