VC6如何修改静态文本的背景色？

MFC程序

Answer 1

自己从CStatic派生一个子类
如果是对话框的话，可以给对话框添加WM_CTLCOLOR消息函数，并将其修改成：
HBRUSH CMyDlg::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor)
{
HBRUSH hbr = CDialog::OnCtlColor(pDC, pWnd, nCtlColor);

// TODO: Change any attributes of the DC here
if(nCtlColor==CTLCOLOR_LISTBOX)
{
//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_SCROLLBAR)
{
//pDC->SetBkMode(TRANSPARENT);
pDC->SetTextColor(RGB(0,0,0));
pDC->SetBkColor(RGB(141,177,229));
HBRUSH b=CreateSolidBrush(RGB(141,177,229));
return b;
}
else if(nCtlColor==CTLCOLOR_EDIT)
{
//pDC->SetBkMode(TRANSPARENT);
pDC->SetTextColor(RGB(0,0,255));
pDC->SetBkColor(RGB(255,255,255));
HBRUSH b=CreateSolidBrush(RGB(255,255,255));
return b;
}
else if(nCtlColor==CTLCOLOR_STATIC) //A
{
pDC->SetTextColor(RGB(0,128,0));
pDC->SetBkColor(RGB(160,180,220));
HBRUSH b=CreateSolidBrush(RGB(160,180,220));
return b;
}
else if(nCtlColor==CTLCOLOR_DLG)
{
pDC->SetTextColor(RGB(0,0,0));
pDC->SetBkColor(RGB(160,180,220));
HBRUSH b=CreateSolidBrush(RGB(160,180,220));
return b;
}
// TODO: Return a different brush if the default is not desired
return hbr;
}
A行即是修改静态文本背景色的一段代码，其他的自己分析（从名称就能看出来干什么用）
