ToolTip in Text inside RichTextBox

Question

I'm working with code editor and I just wanted to add tooltip for everytext that Ill inputed in richtextbox (served as code-editor) .

Till I see this guide right here:

http://www.codeproject.com/Articles/464085/WinForms-RichTextBox-ToolTip-like-Visual-Studios

It's the same thing that I want to find though the time I download it there's a file missing specifically its mainform .

So I just want to ask if how to do it without using any .dll file.

Sample: I type "abc" in rtb then when I mouse hover it a tooltip with text: this is an alphabet will appear. Same as with "123" a when I mousehover tooltip with text: this is a number will appear.

you want in your RTB, When I type "C# is Awesome" you need to get Awesome only in Tooltip or Full Sentence — Akshay Joy
different text as i inputed in rtb could be if possible . if i inputted "C# is Awesome" tooltip with message "its really Awesome" will appear .something like that ... just like what in the link shows but its ok in me if its just a simple tooltip and dont have border ... — Elegiac
"Its really" is Commmon words has to attach with Last Word you typed in RTB. Please tell me the sample Input and output — Akshay Joy
