body: <p>I am doing project in <strong>vb.net</strong>
  I am using a Rich text box on which i can set <strong>different font</strong> (name,size,bold,italic,underline),color to different selected text.
  I am <strong>able to do this in Rich textbox</strong> but i want to create <strong>bitmap</strong> (or assign to picturebox) of this of different text with different font style &amp; color but i am getting not much font as like textbox in image..
