TRying To Replace One Specific Character Of String With New Character Entered By User
Feb 17, 2011
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.

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've got a string like so
Jamie(123)
And I'm trying to just show Jamie without the brackets etc
All the names are different lengths so I was wondering if there was a simple way of replacing everything from the first bracket onwards?
Some others are displayed like this
Tom(Test(123))
Jack ((4u72))
I've got a simple replace of the bracket at the moment like this
mystring.Replace("(", "").Replace(")","")

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.

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.

I'm trying to replace all the carriage return characters in a string obtained from a multi line text box in a Windows Form with the string ", <BR>" so that when I use the string in some HTML it displays correctly.
Function Blah(ByVal strInput As String) As String
Dim rexCR As Object
rexCR = CreateObject("VBScript.RegExp")

so in a program I'm working on in VB.NET I'm trying to make it so I can take in a list of strings (each on a different line). For each line I want to take in the line, and break it up into three parts. The first part goes from the beginning of the string to the first colon in the string, the second part goes from the first colon to the at symbol, and the last part goes from the at symbol to the end of the string.
For example, I'd take in a line of the series of lines: hello:world@yay
I'd want to break it into three separate strings of "hello", "world", and "yay".
How would I do such a thing in VB.NET?

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

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.
