Phase 3: Integrate Further with MFC

Even after Phases 1 and 2 there are still many things you can do to improve your application's integration with MFC and further take advantage of MFC and C++. Phase 3 discusses some of the following additional steps you can take:

• Make GDI calls the MFC way.
• Hook up some of MFC's diagnostic features, such as the Dump and AssertValid functions.
• Convert some of your C data structures to C++ classes.
• Move data structures into the MFC document class.
• Use MFC's serialization protocol to replace some or all of your present file-handling code.
• Move your printing code into the view's OnDraw function.
• Use a different view class such as CScrollView or CFormView, or use a dialog box to implement your application's form-based user interface.
• Replace the use of cbWndExtra and cbClsExtra with class member variables.

In general, the items in this list will simplify your code, relying on MFC to supply most of the standard wiring to Windows that you must do over and over in C, and taking advantage of many MFC features that hide complexity.
