Actually I have made one application and now I need to integrate the help file which is in CHM format with it, I have made one sub menu in the tool bar like this:
Help->Documentation

Whenever I click on documentation then that chm file should open. How to do this task, please help me.

Try the PyCHM library: http://gnochm.sourceforge.net/pychm.html

It hasn't been updated in a while but it should be good enough to do what you need.

But sir, link in this link http://gnochm.sourceforge.net/pychm.html
is not opening. I know one way to do this task that is but this code transfer the execution from existing application to newly opened application after opening new application controls gets off from old application and I can't even do single thing till I don't close the newly opened application. I need to run both these applications separate and concurrently.

Thanks to all, now it's done. Here I am typing its code:


through this function you can open any program separately. But now other problem has came...
