How to access a member variables from another class?

How to access a member variables from another class?

(OP)

I have an sdi program with two dialog boxes with its respectively classes (CDialog1 and CDialog2). Through a bottom in the 1st dialog box I call the second dialog box. In the second dialog box, the user gives the values for some variables. I know that I can obtain the values of the second dialog box from the first dialog box using m_variable=dlg.m_variable in the OnSecondDialog function.

I want to write in two files the variables given by the user in both dialog boxes. How can I access from CApplicationDoc class the values given by the user in both dialogs?
Should I define a member pointer to the CAplicationDoc class in both dialogs (CApplicationDoc *m_pointer;)?

Thanks
