You can use third-party tools like an ActiveX EXE to do this. If you have MS Word installed, then you are in luck. Just create an instance of Word, put the textbox contents into Word document and use SpellCheck method and other properties to get the info.
If you haven't Word installed, you can do the word counting using a piece of code, that increments a counter whenever it reaches a blank (chr(32)). Just note not to count the multiple attached blank characters.
