MFC中给各个控件填充背景颜色的方法

1.给程序设置大背景色，在OnPaint()函数中添加如下代码：

CRect rect;
CPaintDC dc(this);
GetClientRect(rect);
dc.FillSolidRect(rect, RGB(255, 255, 255));
dc.FillPath();

2.给个控件修改背景颜色，先在类向导中添加WM_CTLCOLOR消息，然后就会自动添加OnCtColor()函数：

HBRUSH CMFCApplication1Dlg::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor)
{
    HBRUSH hbr = CDialog::OnCtlColor(pDC, pWnd, nCtlColor);
    CRect rc;
    switch (pWnd->GetDlgCtrlID())
    {
    case IDC_STATIC_GROUP:　　//像GROUP BOX控件要用FillSolidRect()函数来填充背景，我用SetBkColor()不起作用，不知道为什么
        GetDlgItem(IDC_STATIC_GROUP)->GetClientRect(&rc);
        pDC->FillSolidRect(rc, RGB(229, 245, 255));
        return (HBRUSH)GetStockObject(HOLLOW_BRUSH);
    case IDC_STATIC1:
        pDC->SetBkColor(RGB(229, 245, 255));
        return (HBRUSH)GetStockObject(HOLLOW_BRUSH);
    case IDC_STATIC2:
        pDC->SetBkColor(RGB(229, 245, 255));
        return (HBRUSH)GetStockObject(HOLLOW_BRUSH);
    case IDC_STATIC3:
        pDC->SetBkColor(RGB(229, 245, 255));
        return (HBRUSH)GetStockObject(HOLLOW_BRUSH);
    case IDC_STATIC4:
        pDC->SetBkColor(RGB(229, 245, 255));
        return (HBRUSH)GetStockObject(HOLLOW_BRUSH);
    case IDC_STATIC_GROUP2:
        GetDlgItem(IDC_STATIC_GROUP2)->GetClientRect(&rc);
        pDC->FillSolidRect(rc, RGB(255, 255, 204));
        return (HBRUSH)GetStockObject(HOLLOW_BRUSH);
    case IDC_STATIC:
        pDC->SetBkColor(RGB(255, 255, 204));
        return (HBRUSH)GetStockObject(HOLLOW_BRUSH);
    case IDC_BUTTON2:
        GetDlgItem(IDC_BUTTON2)->GetClientRect(&rc);
        pDC->FillSolidRect(rc, RGB(229, 245, 255));
        return (HBRUSH)GetStockObject(HOLLOW_BRUSH);
    default:
        return CDialog::OnCtlColor(pDC, pWnd, nCtlColor);
    }
    return hbr;
}
