本书通过85个实例全面讲述了应用MFC进行Visual C++编程的思想。每个实例均以编写一个应用程序要走的步骤编写。全书共分四部分进行介绍

WzdSlct.cpp -- a select class which cuts, copies and pastes
WzdSlct.h

WzdInfo1.cpp -- some example data classes to cut and paste
WzdInfo1.h
WzdInfo2.cpp
WzdInfo2.h

// Modify the View Class.
/////////////////////////////////////////////////////////////////////

// 1) embed the selection class in the view class
	CWzdSelect	m_select;


// 2) call the selection class to select a list of data class objects
	m_select.Select(GetDocument()->GetInfo1List()->GetHead());

// 3) call the selection class to cut, copy or paste the selection
void CWzdView::OnEditCut() 
{
	m_select.CutSelections(GetDocument()->GetInfo1List());
}
void CWzdView::OnEditCopy() 
{
	m_select.CopySelections();
}
void CWzdView::OnEditPaste() 
{
	m_select.PasteClipboard(GetDocument()->GetInfo1List());
}

// 4) enable/disable the cut, copy, paste menu commands
void CWzdView::OnUpdateEditCut(CCmdUI* pCmdUI) 
{
	pCmdUI->Enable(m_select.SelectionCount());
}
void CWzdView::OnUpdateEditCopy(CCmdUI* pCmdUI) 
{
	pCmdUI->Enable(m_select.SelectionCount());
}
void CWzdView::OnUpdateEditPaste(CCmdUI* pCmdUI) 
{
	pCmdUI->Enable(m_select.CanPasteClipboard());
}
