Hi Manish
Sorry, but I won't be of any help here. As I said earlier,
you will need someone that can construct a Windows Dynamic Link
Library (.DLL) that would allow this to happen. In other words, you
need lots of pizza, soda pop and chocolate to bribe a developer.
About the only way I can fathom you could achieve something
similar is by creating a topic inside your .CHM that would behave
this way. Inside the topic you could insert a Table of Contents
control and use an alternate TOC.
Cheer...
