Replace One Character At A Time In Order To Store Its Index
Mar 31, 2012
I'm trying to replace one character at a time in order to store its index, therefore if the replace is used all characters are changed and I cannot keep the index of all characters.
I'm working on the exercise page 73 (VB 2010 in 24 hours). It's basically a form with 2 text boxes, 2 text labels and a command button. It's really simple and uses this loop to cycle through the items, and tell me the name of them in a Messagebox
I am working on a sub that essentially needs to open a text file, and replace all instances of a certain character with a unicode character. I'm trying to do this by reading the original text file byte by byte, converting it to a character, and then either adding that character to a memory stream or writing the unicode character to the memory stream. Then I'm saving the memory stream to the original file.
I am writing a hangman type game and I am displaying the word to the user in a label as all *'s, but I cannot figure out how to have just one of the *'s changed in the label to the correct letter when the user inputs the correct letter into the text box and clicks the check letter button.Everything else in the program works perfectly, except for this part.[code]When I use the .Replace it changes all of the *'s to the correct selected letter.
the coding is to 'Get input string and put its character into List, and replace the character with other.'but having problem putting each character into List and also replacing it,[code]

I've been working with the substring command and after coding up all the things I needed it to do, I saw a post on here where the "For Each" statement was used basically to do the same thing.Lets say we just want to take a string apart one character at a time and add each character to a label. Which would be more efficient?I made a cheap example to show ...
Code: ABinary = "0110 1100 0001 1011" For x = 0 To Len(ABinary) - 1

The following code is supposed to show in a message box the index of the third a in the string checkme, but when I run the program it doesn't give me the right answer (should be 12, instead I get 9). What am I doing wrong and how would I go about making it work?
So I have software to replace string with string, it's cool but I need code which would replace any given character (for example a) with all strings from textbox.
What i am trying to do is take a character (which is going to be into a variable by user input) and search a string for this character, and save the positions of all character found and then change the same position of these characters in another string for the character that the user inputs. In other words, like a guess a word game. User tryes a guess, i search the string for that letter or number, if it's there replace it on the text box of the GUi, if not save it in another variable as a character that has been tried already, possibly an array.
Lets say I have a label with the text "_ _ _ _ _ ", some underscores. Now what if I want the program to locate the 3rd underscore and replace with something else. Is this possible? I was guessing by getting the character's position first and somehow there is a function that replaces characters by their position.
I have the problem that the DataGridView has obviously a shortcut key for SHIFT + SPACE which seems to select the row.What I would like to have is that pressing SHIFT + SPACE simply adds a space character to the current cursor position within the current cell (like for example in notepad)
