disclaimer: I have only the faintest idea what I'm doing!
I'm trying to get a windows explorer context menu in my app. I can get
the menu to show, but it does not execute any commands (e.g. 'copy')
my code is based on
http://bcbjournal.org/articles/vol4/0006/Using_the_shell_context_menu.htm and
partly on http://netez.com/2xExplorer/shellFAQ/bas_context.html
I'm new to both win32 and pywin32. Any help or advice will be readily
accepted!
Cheers!
Chris.
