How do you remove words that appear like this:

I received aa bad advice a bad suggestion

I want it to look like this from the RichTextBox:

I received a bad suggestion

These words come from my Listbox.

How do I remove words that have been copy/pasted from the ListBox? My listBox is divided into two columns, the Bad words and Good words. The Bad words are those that look like this: a bad advice, while the Good words are those that look like this: a bad suggestion. There are many so when writing, you can find many.

That makes no sense at all. We have no idea what you're trying to do. You're going to have to hit the "Improve question" widget and provide an example of what you're looking for.

Sorry, but I don't work for you. I have my own job that I have to do and meetings to attend. I also have a life to attend to. I answer questions on MY TIME, whenever I have time available, not when you demand.

If you have a list of "bad words", whatever that means, it's a simple matter of search and replace. This is simple string manipulation. Read the documentation on the String class and it's methods for what you can do with it.

Your post is full of bad words. Then need replacement. :-)
Please replace them with those which explain some real problem.

It is a RichTextBox not a List. The words are suggested by the ListBox from its two columns with Bad words that shows the program knows what the user is talking about, and my suggestions which is the Good words.

If I understand your question correctly you are attempting to remove curse words (ex 'sh*t', 'bi^ch', etc.) from a RichTextBox and replace them with something more user friendly. I can agree (to a point) with some of the other comments in this post you should really try actually learning something from the programming experience and not expect the community to do your work for you. To actually attempt and help guide you instead of judge you for your lack of knowledge here are a few links you should really look at to get you started on your current task.
