MFC Design Philosophy Provide an object-oriented interface to the Windows operating system that supports reusability, self-containment, and other tenets of OOP.MFC Design Philosophy Avoid undue overhead on the system or unnecessarily adding to an application's memory requirements Document/View Architecture MFC Class Hierarchy (CObject) Serialization Support Run-time class information support Diagnostics & debugging support

Sample for Windows Programming 1. Rebuild the solution on the first time. 2. Check the classes at the Class View window. 3. Check the function CKingimageView::OnProcess() 4. Check the Menu IDO_KINGIMTYPE at the Resource View window. 5. New image can be saved. 1. Rebuild the solution on the first time. 2. Check the classes at the Class View window. 3. Check the function CKingimageView::OnProcess() pImg is a pointer pointing to the first byte of the image. Add code for assignments here. Be aware of the format of BMP files: "Padding bytes are inserted in order to keep the line of data in multiples of four." More details can be found on Wikipedia or your textbooks. 4. Check the Menu IDO_KINGIMTYPE at the Resource View window. Add any menu buttons and event handlers if you wish. Remember: I recommend that the event handlers should be add to the CKingimageView class. 5. New images can be saved.

TIPS Delete “Debug” folder before submitting. Download .NET https://msdn04.e-academy.com/binghamton_watson/ No images either if they are too big. Submit using dropbox. (Demo) Readme (Template will be provided).
