I have created a program that opens a text file into a RichTextBox1. Now that I have this accomplished I would like to go through the list of text and clean it up. What I have is a list of stats for various people who play an online game. The problem is that there is also stats that are embedded for computer generated players. These are identified throughout the text as having [BOT] at the end of the screen name. Each line of text contains the screen name and their stats. How can I go through the text in the RichTextBox1 and search for [BOT] and remove this line of text?

Put the contents of the textbox into a string, manipulate the string, then replace the box’s contents with the contents of the manipulated string.

You are going to have to create a routine that knows how to “read” (so to speak).

I guess all I really need at this point is to search for [BOT] within a string. If it has it then delete the string otherwise move on. Is there a way that I can search the string and so some type of compare?

You can use the .IndexOf("Pattern") method of a string to find the 1[u]st</u> occurence of a pattern within a string.
You can use .IndexOf("pattern", n) to find the next occurence of a pattern within a string, starting at character #n.

You can use .LastIndexOf("pattern") to find the last occurence of a pattern within a string.
(.LastIndexOf() can also accept a 2nd argument, just like IndexOf())

I got the filter to work. Thanks for the tip. I decided to go with a ListBox rather than a RichTextBox. It was easier to implement in real time and faster. My only problem now is saving the data within the ListBox. How can I save the data in the ListBox to a text file?

.NET has a variety of functions for streaming to a text file. (I believe they are in System.IO...)

Though (I believe) you can directly save the contents of a richtext box, you have to handle the file yourself with a listbox.

It is pretty easy though. You open a stream object having set it to append or replace, then one-line-at-a-time (with .WriteLine) or character-by-character (with .Write) put your data into the file, then close it.
