EN_VSCROLL

[Daniel Canham]

EN_VSCROLL does not work when the Control is a CRichEditCtrl class.

I need to be able to link the v-scrollbars of two CRichEditCtrl's together.

How do you enable the message map EN_VSCROLL in CRichEditCtrl?

if that is impossible is there an equivalent message map? How do I execute a f() when the user moves the v-scrollbar?

you have to implement the ON_NOTIFY function:
/ccode
//in *.cpp file :
BEGIN_MESSAGE_MAP(CMyDlg, CDialog)
//{{AFX_MSG_MAP(CMyDlg)
ON_NOTIFY(EN_MSGFILTER, IDC_RICH, OnMsgfilterRich)
[......]//other messages
//}}AFX_MSG_MAP
END_MESSAGE_MAP()
//where IDC_RICH is declared in resource.h and the OnMsgfilterRich is declared below:

void CMyDlg::OnMsgfilterRich(NMHDR* pNMHDR, LRESULT* pResult)
{
MSGFILTER *pMsgFilter = reinterpret_cast<MSGFILTER *>(pNMHDR);
if(pMsgFilter->msg==WM_VSCROLL)
{
AfxMessageBox("scroll was used")
}
*pResult = 0;
}

//for this function being enable you have to send a message to the end of OnInitDialog() function:

BOOL CMyDlg::OnInitDialog()
{
CDialog::OnInitDialog();
[...]//other declarations

::SendMessage(m_Rich, EM_SETEVENTMASK, 0, ENM_MOUSEEVENTS|ENM_SCROLLEVENTS);
}
//where m_Rich is the richeditctrl control.
//in the *.h file you have:
afx_msg void OnMsgfilterRich(NMHDR* pNMHDR, LRESULT* pResult);

/ccode
that is. I hope it helps you!
