Add mouse event WM_RBUTTONDOWN on a button in Dialog based application.

I have my Dialog class here
class RS_232Conn : public CDialog
      RS_232Conn(CWnd* pParent = NULL);   // standard constructor
      virtual ~RS_232Conn();
    // Insert into the applications .h header file

and I added a mouse message manager:
      afx_msg void OnRButtonDown(UINT nFlags, CPoint point);
Then in the .ccp application I have:
void RS_232Conn::OnRButtonDown(UINT nFlags, CPoint point)
      CPoint m_MousePoint;
      m_MousePoint =point;
      CDialog::OnRButtonDown(nFlags, point);
Now I can get the mouse right button event on my dialog box!
But how to get the mouse rightclick event on a BUTTON on the same Dialog box? Because it doesn't work on BUTTON !

if the IDC is like this?
      ON_BN_CLICKED(IDC_SYSTEMA, OnBnClickedSystema)

This is my question
Thanks for help

Insert a PreTranslateMessage event in your dialog object, then try to trap WM_RBUTTONDOWN message.

Can you explain with some code?
Where I have to insert this PreTranslateMessage function?
Jaime OlivaresSoftware ArchitectCommented:
Invoke the ClassWizard, pressing Ctrl-W, select your RS_232Conn object class, select the PreTranslateMessage event and create a function to handle it by pressing the AddFunction button.
Then go to edit the created function directly in you code.

BOOL RS_232Conn::PreTranslateMessage(MSG* pMsg)
    if (pMsg->message==WM_RBUTTONDOWN) {
         MessageBeep(MB_OK);   // test function
         // Pût your real action code here
    return CDialog::PreTranslateMessage(pMsg);
