Background color

[Nelek]

Take a look in SetBkColor ()

Greetings. -------- M.D.V. If something has a solution... Why do we have to worry about?. If it has no solution... For what reason do we have to worry about? Help me to understand what I'm saying, and I'll explain it better to you ;)

you need to SUBCLASS that control to achieve same.. search SUBCLASS by mr Chris!

Thank for your reply. The SUBCLASS change the background color by the mouse movement. I need to change the color when it was focused by mouse or tab order. Could you help me? Thanks

Not true. Consider this code (dots are code that's been omitted): ================================================================= In ".h" file. ------------- class CFocusColourDlg : public CDialog { . . . // ClassWizard generated virtual function overrides //{{AFX_VIRTUAL(CFocusColourDlg) protected: virtual void DoDataExchange(CDataExchange* pDX); // DDX/DDV support virtual BOOL OnCommand(WPARAM wParam, LPARAM lParam); //}}AFX_VIRTUAL // Implementation protected: HICON m_hIcon; CBrush m_RedBrush; // Generated message map functions //{{AFX_MSG(CFocusColourDlg) virtual BOOL OnInitDialog(); afx_msg void OnPaint(); afx_msg HCURSOR OnQueryDragIcon(); afx_msg HBRUSH OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor); afx_msg void OnDestroy(); //}}AFX_MSG DECLARE_MESSAGE_MAP() }; In ".cpp" file. --------------- . . . BEGIN_MESSAGE_MAP(CFocusColourDlg, CDialog) //{{AFX_MSG_MAP(CFocusColourDlg) ON_WM_PAINT() ON_WM_QUERYDRAGICON() ON_WM_CTLCOLOR() ON_WM_DESTROY() //}}AFX_MSG_MAP END_MESSAGE_MAP() ///////////////////////////////////////////////////////////////////////////// // CFocusColourDlg message handlers BOOL CFocusColourDlg::OnInitDialog() { CDialog::OnInitDialog(); // Set the icon for this dialog. The framework does this automatically // when the application's main window is not a dialog SetIcon(m_hIcon, TRUE); // Set big icon SetIcon(m_hIcon, FALSE); // Set small icon // TODO: Add extra initialization here m_RedBrush.CreateSolidBrush(RGB(255, 0, 0)); return TRUE; // return TRUE unless you set the focus to a control } . . . BOOL CFocusColourDlg::OnCommand(WPARAM wParam, LPARAM lParam) { WORD NotifyCode = HIWORD(wParam); WORD Id = LOWORD(wParam); HWND hWnd = reinterpret_cast(lParam); if (NotifyCode==EN_SETFOCUS || NotifyCode==EN_KILLFOCUS) { ::InvalidateRect(hWnd, NULL, TRUE); } return CDialog::OnCommand(wParam, lParam); } HBRUSH CFocusColourDlg::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor) { HBRUSH hbr = CDialog::OnCtlColor(pDC, pWnd, nCtlColor); if (pWnd->GetSafeHwnd() == ::GetFocus()) { pDC->SetBkColor(RGB(255, 0, 0)); return m_RedBrush; } return hbr; } void CFocusColourDlg::OnDestroy() { CDialog::OnDestroy(); m_RedBrush.DeleteObject(); } Steve

You could subclass it or use this[^] approach.

but according to OPPs principal.. i am just abstracting that thing from outer world i.e. Dialog!

This approach doesn't necessarily break OOP principles; there's nothing wrong with an edit control asking its parent what colour it should use.
