Right mouse button event handler

MFC does not allow to trap all the events on the CButton control but some commonly used events like BN_CLICKED and BN_DOUBLECLICKED and so to trap a right mouse button events on a CButton MFC you need to derive a new class from the CButton.

MyButton.h

Code: CPP

class CMyButton : public CButton
{
// Construction
public:
  CMyButton();

// Attributes
public:

// Operations
public:

// Overrides
  // ClassWizard generated virtual function overrides
  //{{AFX_VIRTUAL(CMyButton)
  //}}AFX_VIRTUAL

// Implementation
public:
  virtual ~CMyButton();

  // Generated message map functions
protected:
  //{{AFX_MSG(CMyButton)
  afx_msg void OnRButtonUp(UINT nFlags, CPoint point);
  //}}AFX_MSG

  DECLARE_MESSAGE_MAP()
};

MyButton.cpp

Code: CPP

BEGIN_MESSAGE_MAP(CMyButton, CButton)
  //{{AFX_MSG_MAP(CMyButton)
  ON_WM_RBUTTONUP()
  //}}AFX_MSG_MAP
END_MESSAGE_MAP()

/////////////////////////////////////////////////////////////////////////////
// CMyButton message handlers

void CMyButton::OnRButtonUp(UINT nFlags, CPoint point) 
{
  // TODO: Add your message handler code here and/or call default
  NMHDR hdr;
  hdr.code = NM_RCLICK;
  hdr.hwndFrom = this->GetSafeHwnd();
  hdr.idFrom = GetDlgCtrlID();
  TRACE("OnRButtonUp");
  this->GetParent()->SendMessage(WM_NOTIFY, (WPARAM)hdr.idFrom, (LPARAM)&hdr);
}

Now in your Dialog class you need to trap the Message that your CMyButton passes. The message passed is NM_RCLICK and you capture it as

Code:

  ON_NOTIFY(NM_RCLICK, IDC_BUTTON1, OnRClicked)

  ON_NOTIFY(NM_RCLICK, IDC_BUTTON2, OnRClicked)

Your member function must be declared with the following prototype:

afx_msg void memberFxn( NMHDR * pNotifyStruct, LRESULT * result );

afx_msg void OnRClicked( NMHDR * pNotifyStruct, LRESULT * result )

iam getting undeclared error in _beginthread
process.h included
this has been done
"Project|Settings|C/C++|Code generation|Use runtime library: (Debug)
> multithreaded"
getting unresolved error in linking:_fun()@1

solution plz
