重新ON_WM_PAINT()、ON_WM_CTLCOLOR()消息对应的函数OnPaint()、OnCtlColor()
（一）OnPaint()
//CDialogEx::OnPaint();
CRect rect;
CPaintDC dc(this);
GetClientRect(rect);
dc.FillSolidRect(rect, RGB(217, 226, 241)); //设置为浅蓝色背景
（二）OnCtlColor()
HBRUSH hbr = CDialogEx::OnCtlColor(pDC, pWnd, nCtlColor);
// TODO: 在此更改 DC 的任何特性
if (nCtlColor == CTLCOLOR_BTN) //更改按钮颜色
{
//pDC->SetBkMode(TRANSPARENT);
pDC->SetTextColor(RGB(0, 0, 0));
pDC->SetBkColor(RGB(1, 121, 255));
HBRUSH b = CreateSolidBrush(RGB(121, 121, 255));
return b;
}
else if (nCtlColor == CTLCOLOR_SCROLLBAR) //
{
//pDC->SetBkMode(TRANSPARENT);
pDC->SetTextColor(RGB(0, 0, 0));
pDC->SetBkColor(RGB(233, 233, 220));
HBRUSH b = CreateSolidBrush(RGB(233, 233, 220));
return b;
}
else if (nCtlColor == CTLCOLOR_EDIT) //更改编辑框
{
//pDC->SetBkMode(TRANSPARENT);
pDC->SetTextColor(RGB(0, 0, 0));
pDC->SetBkColor(RGB(246, 246, 246));
HBRUSH b = CreateSolidBrush(RGB(246, 246, 246));
return b;
}
else if (nCtlColor == CTLCOLOR_STATIC) //更改静态文本
{
pDC->SetTextColor(RGB(0, 0, 0));
pDC->SetBkColor(RGB(217, 226, 241));
HBRUSH b = CreateSolidBrush(RGB(217, 226, 241));
return b;
}
else if (nCtlColor == CTLCOLOR_DLG) //更改对话框背景色
{
