BASIC EVENT HANDLING

Ex:

#include<afxwin.h>

classMyFrame:publicCFrameWnd

{

public:MyFrame()

             {

                   Create(NULL,"Simple Window");

             }

          voidOnLButtonDown(UINT flag,CPointpt)//Mouse Event Handler

             {

                   MessageBox("Left Button Pressed");

             }

          voidOnKeyUp(UINT ascii,UINTnrpt,UINT scan)//Key Board Message Handler

             {

                   MessageBox("Key is pressed");

             }

             DECLARE_MESSAGE_MAP()

};

BEGIN_MESSAGE_MAP(MyFrame,CFrameWnd)

ON_WM_LBUTTONDOWN()

ON_WM_KEYUP()

END_MESSAGE_MAP()

classMyMain:publicCWinApp

{

public:intInitInstance()

             {

                   MyFrame *f=new MyFrame();

                   f->ShowWindow(1);

                   m_pMainWnd=f;

                   return 1;

             }

};

MyMain m;
