return key pressed event from clistctrl

hi i put a listctrl in a framewnd ,i wanna do some works when the user press return key when a list item is selected ,i tried NM_RETURN event but it doesn't work ,some one can help me??

Override CListCtrl with CYourListCtrl and override PreTransLateMessage with something like that:

Code:

---

BOOL CYourListCtrl::PreTranslateMessage(MSG* pMsg)
{
        if( pMsg->message == WM_KEYDOWN )
        {
                if(pMsg->wParam == VK_RETURN)
                {
                        ::TranslateMessage(pMsg);
                        ::DispatchMessage(pMsg);
                        return TRUE;                            // DO NOT process further
                }
        }
       
        return CListCtrl::PreTranslateMessage(pMsg);
}

Processing Keyboard Messages

Ah, Reorx, that's a little 'brute force' for me :

Try this :

Code:

---

// in.cpp
BEGIN_MESSAGE_MAP(CMyInheritedListCtrl, CListCtrl)
    ON_WM_KEYDOWN()
END_MESSAGE_MAP()

// in .h
afx_msg void OnKeyDown(UINT nChar, UINT nRepCnt, UINT nFlags);

// in .cpp
void CMyInheritedListCtrl::OnKeyDown(UINT nChar, UINT nRepCnt, UINT nFlags)
{
    CListCtrl::OnKeyDown(nChar, nRepCnt, nFlags);

    if (nChar == VK_RETURN)
    {
        // yep it's trapped - do whatever you want
    }
}

I prefer not to use PreTranslateMessage otherwise you'll end up with everything in it if you're not careful.

It is not the solution Microsoft programmers and MFC experts use.

Most people that understand the solutions used by experts choose not to use PreTranslateMessage.
