Update of /cvsroot/pywin32/pywin32/com/win32comext/shell/demos/servers
In directory sc8-pr-cvs1:/tmp/cvs-serv23533
Added Files:
shell_view.py
Log Message:
First cut at a shell view implementation, which is very very sparse, but
does create a window!
--- NEW FILE: shell_view.py ---
# A sample shell namespace view
# To demostrate:
# * Execute this script to register the namespace.
# * Open Windows Explorer
# * Note the new folder hanging off "My Computer"
# This is still incomplete - but we *do* create a view window - we just do
# nothing with it.
