ComboBox由两个控件组合而成，你想改变什么地方的背景？

映射WM_CTLCOLOR消息即可(设ComboBox的ID为IDC_COMBO1)
HBRUSH CCb3Dlg::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor)
{
static HBRUSH cbhdr = ::CreateSolidBrush(RGB(255, 192, 150));
CWnd *pParent = pWnd->GetParent();

if(pWnd->GetDlgCtrlID() == IDC_COMBO1 ||
(pParent && pParent->GetDlgCtrlID() == IDC_COMBO1))
{
pDC->SetBkColor(RGB(255, 192, 150));
return cbhdr;
}
return CDialog::OnCtlColor(pDC, pWnd, nCtlColor);
}
