Everyone take note please - I changed the registry!
If you change a registry entry that is being used by
another application, it's a good idea to let that application know what
you did so that it's able to update / refresh itself.
Problem is, you may not be aware of which programs could
be affected by you editing the registry. So, why not send
a message to all the windows notifying them about your
action as follows:
LongInt( PChar( 'RegistrySection' ) )
is of course the registry section which you changed.
If you're using Windows 95, you may have to use "WM_SETTINGCHANGE" message
instead of "WM_WININICHANGE."
Also, it's possible to use Win32 API function "SystemParametersInfo()" to
send out more specific notices about registry and/or
system parameter changes you make.
