第五種: hbr= CreateBrushIndirect(LOGBRUSH); //通過LOGBRUSH結構體來取畫刷

COLORREF lbColor; //顏色
LONG lbHatch; //陰影

HGLOBAL hglbDIBPacked, // handle to DIB
UINT fuColorSpec // color table data
); 例如： HBRUSH CAfdView::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor)

static HBRUSH hBrush = CreateSolidBrush(RGB(222,0,255));
return hBrush;
}
// TODO: Return a different brush if the default is not desired
else
return hbr;
} 改變對話方塊背景色 HBRUSH CDqfDlg::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor)
{
HBRUSH hbr = CDialog::OnCtlColor(pDC, pWnd, nCtlColor); // TODO: Change any attributes of the DC here // TODO: Return a different brush if the default is not desired
if(nCtlColor == CTLCOLOR_DLG)
