    stupid question again, help.

    Hi
    if I have a Slider control on my CFormview then it is always on Focus. My question is:
    1. is that posible to set it un-focus if I click the mouse somewhere else? so

    2. If I overide the functions: OnkeyDown, onKeyUP from CSliderCtrl , how to call the OnKeyDown() , OnKeyUp() the class that handle the view?

    class CACPTESTView : public CFormView
    {
    public:
    afx_msg void OnKeyDown(UINT nChar, UINT nRepCnt, UINT nFlags);
    }

    class CSliderCtrl2 : public CSliderCtrl
    {
    afx_msg void OnKeyDown(UINT nChar, UINT nRepCnt, UINT nFlags);
    }

    CSliderCtrl2::OnKeyDown(.....)
    {
    how to call the CACPTESTView::OnKeyDonw(...);
    }


    Thanks in millions.

    1) I dont think so. Not if it is the only control. You could only place a dummy control somewhere else that gets the focus.

    2)

    I think the slider control is placed in the CACPTESTView, if that is so:

    CSliderCtrl2::OnKeyDown(.....)
    {
    CACPTESTView* pView = (CACPTESTView*) GetParent();
    pView->OnKeyDown(...);
    }

    A more conviencing way MIGHT be (normally the better way in more complex applications):
    1) defining a new USER message (e.g. in CACPTEST.h):
    #define WM_USER_ONSLIDERKEYDOWN WM_USER + 1

    2) Send or post the message to the Parent window
    CSliderCtrl2::OnKeyDown(.....)
    {
    GetParent()->SendMessage( WM_USER_ONSLIDERKEYDOWN, ... );
    // or - for assynchronous execution without feedback via return value:
    // GetParent()->PostMessage( WM_USER_ONSLIDERKEYDOWN, ... );
    }

    3) Create a handler for the WM_USER_ONSLIDERKEYDOWN message in the View class:
    3a) add ON_MESSAGE( WM_USER_ONSLIDERKEYDOWN, ...) in the MESSAGE_MAP area of APCTESTView.c
    3b) add an corresponding message handler method to CAFXTESTView class.
