关于设置背景的一个小问题

[dg115]

为什么我在程序中用pdc->setbkcolor(rgb());设置窗口背景色后，编译运行却不能得到如期结果？仍然是默认背景？请大虾指教。

你应该添加OnCtlColor（）函数，下面给你一个实例：
if(nCtlColor == CTLCOLOR_STATIC)
{

switch(pWnd->GetDlgCtrlID())
{
case IDOK:
pDC->SetTextColor(RGB(0,255,0));
pDC->SetBkColor(RGB(192,192,2));
break;

case IDC_NUM:
pDC->SetTextColor(RGB(0,255,0));
pDC->SetBkColor(RGB(0,0,0));
break;
case IDC_EDIT1:
pDC->SetTextColor(RGB(0,255,0));
pDC->SetBkColor(RGB(0,0,0));
break;

}
}
if(nCtlColor == CTLCOLOR_EDIT)
{
pDC->SetTextColor(RGB(255,255,255));
pDC->SetBkColor(RGB(192,192,192));
}
if(nCtlColor == CTLCOLOR_DLG)
{
pDC->SelectObject(&m_brush);
pDC->SetTextColor(RGB(255,255,255));
pDC->SetBkColor(RGB(0,0,0));
}
if(nCtlColor == CTLCOLOR_BTN )
{
CBrush brush;
brush.CreateSolidBrush(RGB(100,100,220));
pDC->SelectObject(&brush);
pDC->SetTextColor(RGB(0,255,255));
pDC->SetBkColor(RGB(0,0,0));
}
