I have a block of text in a text .txt file that looks like this: [code]I've tried reading every character and entering them into a 2D array (failed)I've tried splitting them into individual lines and entering them into a 1D array (Success, but very difficult to target individual characters from this, and will take a long time to set up as I only did this for 10 lines)

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.

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 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.

In 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.

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?

I have 2 files:

2.) TempHeader.txt (Header)
In my program, I'm reading each file with the StreamReader, then prepending the header onto the original file to create a 3rd file which is the combination of the two. My problem is that the original file contains the following:

All I would like to do is remove one character from the line of the text file that I am reading, which is the first character and also prevent the program from crashing if no text file is present.Here is the code. Can anyone notice where I am going wrong? I thought the "if" statement would cover the crash but it didn't. Clueless, but sort of have an idea on the character removal.

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"

I am running Visual Basic Express 2005. I am trying to develop a program to send morse code out the serial port. I have created working code that can determine which character needs to be sent and toggles the RTS line on com 1 with the proper pulses. What I can't seem to figure out is how to be able to type in characters at a higher speed than they will be sent out the port, so as to be able to use the backspace key etc.

I have recordsets in my MySQL database like this (in german): Karrieren im Porträt: Interview mit Thorsten Franck - „Ich liebe Produkte" Now when I get the data with the MySQL connector reader and write it into an xml file I get just this: Karrieren im Porträt: Interview mit Thorsten Franck Ich liebe Produkte As you (hopefully) can see, the minus (it's one of those long ones) and the upper and lower quote signs are not shown. The table is defined as UTF-8, the output of the xml file also.
