What exactly are you trying to achieve? You can add a variable in the constructor or any method of the CDialog class. Adding the same function to both would be a little more work.

Solution 2

Assuming the dialogs share same parent window, any public method of such parent window is accessible to both.
E.g. suppose the parent window (say MainWindow) implements a public method (say getMass()), then, in any of dialogs you may write:

C++

MainWindow *pmw = reinterpret_cast<MainWindow *> (GetParent());
int mass = pmw->getMass();

You need some common data, possible is it as member in a permanent class object (like the app or document) or as global object. You can this achieve via some PostMessage architecture and send the data as parameters, or as global model object which is accessable via pointers to both dialogs.
