Hi Stephan,
Thanks for sharing Alex's sample with us.
However it has no way to turn on/off the visual style on the runtime,
unless to redraw each control in the app manually to mimic the theme, but
that seems too complicated.

| The function you outlined are global settings.
| So far, their is no real elegant solution to turn on off the style on the
fly
| but Alex Feinman showed me this solution (See his post below) to allow
this to be done at startup time.
|
| In short it manually load the manifest using the "Activation Context
Reference" API.
|
| Stephan
|
| To do this you use CreateActCtx function to create activation context
prior to any window-creating activity. The activation context
| will still require a manifest file, but whether to use it will be
decided programmatically.
|
| I've put together an MFC sample for you:
http://www.alexfeinman.com/download.asp?doc=ThemedApp.zip
|
| If you look inside InitInstance, you will find a call to ActivateContext
function, which performs the actual work.
|
| Naturally, due to the way theming is implemented, you will not be able to
switch theming support on the fly; at least not without
| recreating your windows.
| If you activate context prior to displaying a dialog, the dialog will be
created with theme support
