I have developed a phone book for personal use.  I am trying to
incorporate a feature to dial the phone numbers with a click of a button.
Please give me the source code and example on how to dial a number that is
displayed on a text box.  Do I need to format the phone number in a
special format (eg: (000) 000-0000, 000-000-0000).  

I highly appreciate your help.
