  1. (10%) Consider the OnUpdateColorRed() function in P.826, if we modify its definition as follows, how will the program behave differently?
    void CSketcherDoc::OnUpdateColorRed(CCmdUI *pCmdUI)
    {
    	if (m_Color==BLACK) 
    		pCmdUI->Enable(0);
    	else
    		pCmdUI->Enable();
    }



  2. (10%) Please refer to P.816. In the example of Chapter 14, we created the message handler OnColorBlack() to be a member function of the class CSketchDoc. Can the program still work if we created it as a member function of the class CSketchView?  Why or why not?
    (Certainly, we assume the data members m_Element and m_Color are also created in the class CSketcherView.)
