When I add string data to a textbox, such as textBox.AppendText("my text"), it shows the end of string character, 0x00, as a box. This does not happen under Windows 7 but does in Windows XP. It is very annoying to see the box at the end of every string that is displayed. How can I prevent it from showing?

Dim hex = "41"
Dim text As New System.Text.StringBuilder
For i As Integer = 0 To hex.Length - 2 Step 2
text.Append(Chr(Convert.ToByte(hex.Substring(i, 2), 16)))

but yet this fails.. (the output isn't itself in a new line) what's the explanation for that?From what I know, doesn't System.Diagnostics.Debug.Writeline does something which looks like this:
System.Diagnostics.Debug.Write(input)
System.Diagnostics.Debug.Write("
")
so regardless of my input it should always have a newline char even if there is a terminating 00 char in my input?
I have a textbox where the user inputs a string.
I want to take the string, and output each character into a seperate textbox.[code]...
I have a program where a user puts a string into a textbox, and then character one goes into Textbox1, char2 goes into TB2, char3 goes into TB3, etc. I have a For loop that gets all of my textboxes that are used for this, and I have my for loop that is supposed to go through my string character by character.

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.

I am a student working on the venerable "Hangman" project. We were tasked to create a hangman game that would get a random word from one of three sources either by file, by array, or by database file. I have managed to get a random word to import from all three but I run into a problem once I start to play the game. The program seems to run into an infitinite loop as soon as you enter a letter or it automatically dispays character entered and gives a game over. [code]............

Which would be more efficient?I made a cheap example to show ...

I'm making a program that displays information for a dungeons and dragons game. i have a main form that displays all the information from a .txt file. I've made a new form that creates a new character. on this forum there are currently 7 text boxes and 6 combo boxes all containing different information for the new character.
The problem is now i want to save the new text file with each line of the text boxes and combo boxes on separate lines in the text file. My current plan was to put all the text from the 7 text boxes and combo boxes into one "main" text box then save that text box.
