In the page 1159, I must to add an event to each button that is in the IDD_CUSTOMER_FORM but I can´t make this. When I try to make this an error is
produced. The program says me that CCustomerView is a only read file and I can´t modify this.
Why?
Can I modify CCustomer.h or CCustomer.cpp to make this files accesible?
Because of this I can´t change the view of the program, from custimer view to product view or from product view to order view, etc.

I need assistance, please.
