怎么动态改变CComboBox控件背景色？有知道的吗

Answer 1

HBRUSH m_hBlueBrush;

BOOL CYourDialogDlg::OnInitDialog()
{
CDialog::OnInitDialog();
// ...
m_hBlueBrush = CreateSolidBrush(RGB(0, 78, 152)); // 蓝色刷子
// ..
}

HBRUSH CYourDialogDlg::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor)
{
HBRUSH hbr = CDialog::OnCtlColor(pDC, pWnd, nCtlColor);

switch(nCtlColor)
{
case CTLCOLOR_LISTBOX:
return m_hBlueBrush;
}

return hbr;
}
