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.

View 2 RepliesHow would you select the last part of a string starting at a specific character count. For example I would like to get all text after the 3rd comma. but I get an error saying "StartIndex cannot be less than zero."
Dim testString As String = "part, description, order, get this text, and this text"
Dim result As String = ""
result = testString.Substring(testString.IndexOf(",", 0, 3))
I have a simple text file containing a list of names that I wish to sort. I was hoping for something simple like:
System.IO.File.ReadAllText("MyFile.txt")
System.IO.File.Sort("MyFile.txt")
System.IO.File.WriteAllText("MyFile.txt")
or something like that. Didn't want to actually write a bubblesort/quicksort routine myself.
I would imagine the routine would just rewrite the final file or would I have to make a new file and copy the contents back to the original?
Let's say I have a textfile which contains paragraphs. Some of the paragraphs start with * or a > character. How do I index the words that start with these characters?

View 3 RepliesI 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.

View 7 RepliesIn my VB.NET application I compare words that are recorded using IPA, many of which have many diacritic marks. In one of the comparisons, I compare the words character by character. But when I iterate over the characters, the diacritic marks come out as separate characters (as I would expect since this is unicode)However, a u character is different than a u plus an accent for the purposes of this program and needs to be distinguished.
