I will answer to myself :)
HBRUSH CMYDlg::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor)
{
HBRUSH hbr = CDialog::OnCtlColor(pDC, pWnd, nCtlColor);
CPaintDC dc(this);
if(nCtlColor == CTLCOLOR_EDIT && pWnd->GetDlgCtrlID() == IDC_MYCOMBO) {
pDC->SetTextColor(RGB(0, 0, 0));
pDC->SetBkColor(RGB(255, 90, 90));
hbr = m_myBrush;
}
return hbr;
}
may be it will help to others someday.
