Subclassing

[voorugonda prashanth]

what is subclassing actually?? how do u create a subclass in SDK and MFC? Thanks in advance Regards, Prashanth.v

subclassing is not a MFC nor SDK concept but a C++ (and even general OO) concept. it means using a base class to reuse its behavior/design/methods and not reinventing the wheel... another good term for this is also inheritence

can u please give me a example????

[toxcct]

class BaseClass {
int m_iSize;

public:
int getSize() { return m_iSize; }
void setSize(int i) { m_iSize = i; }
};

class ChildClass : public BaseClass {
double m_dPrice;

public:
double getPrice() { return m_dPrice; }
void getPrice(double d) { m_dPrice = d; }
};

then, you use it like any object which contains all...

ChildClass cc;
cc.setSize(4);
