VB .NET code to highlight words (including hyphenated words) using Acrobat.tlb Type Library in .pdf files

I have an existing VB .NET Winforms Application. My application loops through .pdf files searching for words (some of which are hyphenated). These words are output to a text file. I need the words from 2 lists highlighted inside the .pdf in respective colours (good green, bad yellow) and the file saved as a new .pdf. I need: VB .NET application (Solution Including Source Code) Single Form >> Select .pdf button (button is pressed OpenFileDialog appears, file is selected). ListBox1: Good Word List 1 (List of words to search for in file (highlight in green)) ListBox2: Bad Word List 2 (List of words to search for in file (highlight in yellow)) Word List 1 is searched for in file. When word is found it highlights in Green. Word List 2 is searched for in file. When word is found it highlights in Yellow. Please note: Must be able to find and highlight hyphenated words. I have written code myself to do this but cannot find the hyphenated word, hence posting this project. Please only bid on the project if you can highlight the hyphenated words. Thanks.. look forward to hearing from you...
