Hello everyone!!!!

I have a nested propertysheets (on some propertypages I have another propertysheet with pages itself). I have also a XML file of general settings that I read in OnInitDialog()'s form event.
Some pages of this nested propertysheets have settings that depends from other pages and of general settings from xml file. Like if I activate a checkbox in a page I change in the xml file the related value from 0 to 1 and in the same time I enable the controls in another page.
I know there's a way to communicate between propertypages from the top (the dialog form) so it can share also xml file object maybe using DoDataExchange to reduce complexity.
But how I can do that?... I tried to read the help of MSDN but it's like messing me a bit so I'm here asking you...

Thanks to all.
Ciao
