编辑框中文字部分是白的，我现在想要它变成RGB(63, 63, 70)。
要求：父窗口中不做任何修改，只在CGreyEditControl中做修改实现
以下是代码：（部分）
//父窗口CPP WM_CTLCOLOR -> OnCtlColor
HBRUSH CGreyDlg::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor)
{
HBRUSH hbr = CDialogEx::OnCtlColor(pDC, pWnd, nCtlColor);
if (pWnd->GetDlgCtrlID() != MY_EDIT)
{
pDC->SetBkColor(RGB(37, 37, 38));
pDC->SetBkMode(TRANSPARENT);
pDC->SetTextColor(RGB(255, 255, 255));
return CreateSolidBrush(RGB(37, 37, 38));
}
return hbr;
}
