I am trying to detect a right mouse button cllick in an edit control within a dialog.
I have coded :
BEGIN_MESSAGE_MAP
   On_WM_RBUTTONDOWN()
  ...
END_MESSAGE_MAP

-- in dialog class definition --
Protected:
  afx_msg void OnRButtonDown(UINT nFlags, CPoint point);
  ...

-- in dialog class coding --
void CSect2::OnRButtonDown(UINT nFlags, CPoint point)
{
    CWnd*  pCurWnd;

   pCurWnd = WindowFromPoint(point);
   if (pCurWnd == GetDlgItem(IDC_ITEM))
   {
       ......
   }

In debug mode, I get a break if mouse cllick is in dialog window outside of the edit control, but no break if mouse click is in edit control.
How do I detect a right mouse click in the edit control ?
Any help is appreciated.  Thanks.

One way you can deal with this is to subcalss the MFC Edit
control.

A reference for this process is "Inside Visual C++", page
346 ff.

Assume you have a edit field IDC_EDIT1.

Construct a new class CMyEdit which derives from CEdit.

In that class, map the WM_RBUTTON_DOWN message as you
did in the example above.

Write a handler for CMyEdit::OnRButtonDown.

Declare a CMyEdit in your dialog class definition.
Lets say that you call it m_foo.

In your OnInitDialog function for your dialog class:

m_foo.SubclassDlgItem(IDC_EDIT1, this);
