Find Hex Symbol/Character In A String?
Jun 18, 2012I have a string of text being sent through a serial port to a text box (Text1.Text). The string has some symbols in in which I am assuming are Hex values. The hex values are Hex(1), Hex(4), Hex(12), and Hex(17). What I need to do is find the position of these hex symbols in the string of text so that I can split or grab the data after the specific hex symbol. I am not able to use substring or indexof or instr ... or at least I am not using it correctly to find the appropriate symbol.I was thinking if I need to iterate through the string character by character and grab each symbol or text and get their value??? If it is one of the hex symbols, then get the index number (or position).

VS 2008 Random - New Character Out Of The String And Then Remove The Character From The List Of Characters
Dec 12, 2010[Code]...
For each character of this string I want a new character out of the string and then remove the character from the list of characters that still maybe used for other characters. It may not get the same character, you could basically just call this encryption, but it's not what I am making. I don't want to waste my time doing this one hour while VB can do this for me in <1 second.

Oct 31, 2011I am trying to develop a HANGMAN game and i need to implement a button where the user can click on it to "buy" letters. So, i designated 2 text boxes (one visible containing stars and another one not visible containing the word that should be guessed), and i wrote the following piece of code so that once the user presses the button any of the stars will turn to the correct letter. My question is, i found the index of "*" and removed it, and now i want to insert the corresponding char with this index (WordInLetters). How can i find what char is at index "index" in vb.net?
