title: Highlight text in a richtextbox in windows forms
body: <p>How to make when i type in a <code>RichTextBox</code> a certain word it gets highlited? </p>
  
  <p>how do i find words in the text to use <code>SelectionColor</code> or <code>SelectionFont</code> </p>
  
  <p>For example: i want that all times that the word "hello" appear in the <code>RichTextBox</code> it turn to <strong>bold</strong> or turn into a color...</p>
  
  <p>Then if i open my program and type "<strong>hello</strong>, how are you?" the word hello turns into bold... any idea? (my idea is to make a text editor with syntax highlight that ill specify the words)</p>
  
  <p>(sorry if there is another question like that, i tried to search but i didn't find a answer that helped me)</p>
  
  <p>its windows forms, visual basic</p>
