How to exchange data between two dialogs

[Que]

I don't know how to exchange data between 2 dialogs. Can I use global variable? If yes, how and where (or what file I can put it into?)
Is there other ways.
Thanks

Better use public variables in your dialogs. For example, to exchange text from one dialog to the other do this:

m_dlg1_text = dlg2.m_dlg2_text;

or

dlg1.m_dlg1_text = dlg2.m_dlg2_text;

This will keep the OO concept untainted.

And if you have no choice but to use global variable, global variable are declared in the MyApp.h/cpp files and use with theApp object
