Hello All
Further to this original post.
It is possible to integrate the CHM files produced by this program to Windev at the window level.
I didn't realise that chm files could be referenced by their internal page ID number but Windev can call these numbers using the Whelp() command so you can make the help context sensitive to a window and open the relevant chm page from a help button on each window.
The software produces three versions of the help system, chm help file , html help web pages and text based help in an rtf file.
Regards
Al
