Thread: 'm_dlgColor' : undeclared identifier in B.cpp error....

i guess i already understand what you said. thanks!
And furthermore questions.

A.h

Code:

Public:
COLORREF   m_dlgColor;

// declare the member at head file.

A.cpp
[code]
class ObjectA {
public:
int m_intA;
// Q1, What's the different Or reason, if i declare member of "m_dlgColor" here ?
void bob_functionA(void);
};



B.h

Code:

Public:
COLORREF   m_dlgColorObjectB;

B.cpp

Code:

class ObjectB {
    public:
        int m_intB;
        void bob_functionB(void);
        {
         // Q2: try to initialization Or Asign value via the following statement ?
         m_dlgColorObjectB = ObjectA.m_dlgColor
        }
        
};

Q3. Does the bob_functionB() Could be filled outside of Class ObjectB? What's the different between fill the member function inside the class or outside of the class?
