请问，我可不可以把FromView的背景刷成白颜色的？怎么刷？

Answer 1

先
BOOL CPrintView::OnEraseBkgnd(CDC* pDC) 
{
// TODO: Add your message handler code here and/or call default
// 设置所要求背景色的刷子
   CBrush backBrush(RGB(225, 225, 225));
    // 保存旧刷子
    CBrush* pOldBrush = pDC->SelectObject(&backBrush);
    CRect rect;
    pDC->GetClipBox(&rect);     // 擦除所需的区域
       pDC->PatBlt(rect.left, rect.top, rect.Width(), rect.Height(), PATCOPY);
    
    pDC->SelectObject(pOldBrush);
    return TRUE;
return CFormView::OnEraseBkgnd(pDC);
}HBRUSH CPrintView::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor) 
{
HBRUSH hbr = CFormView::OnCtlColor(pDC, pWnd, nCtlColor);

// TODO: Change any attributes of the DC here
CRuntimeClass* prt=pWnd->GetRuntimeClass();
switch (nCtlColor)
{
//case CTLCOLOR_LISTBOX:
case CTLCOLOR_STATIC:
{
               pDC->SetBkMode(TRANSPARENT);

               COLORREF    color;
               //color = (COLORREF) GetSysColor(COLOR_BTNFACE);
     color=0x00E1E1E1;
   delete back_brush;
               back_brush = new CBrush(color);
               return (HBRUSH) (back_brush->m_hObject);
   break;
}

case CTLCOLOR_EDIT:
{
if(pWnd==GetDlgItem(IDC_EDIT_DISCOUNT5) && m_bDiscount5==FALSE){
pDC->SetBkMode(TRANSPARENT);
pDC->SetTextColor(RGB(255,0,0));
}else if(pWnd==GetDlgItem(IDC_EDIT_DISCOUNT6) && m_bDiscount6==FALSE){
pDC->SetBkMode(TRANSPARENT);
pDC->SetTextColor(RGB(255,0,0));
}else if(pWnd==GetDlgItem(IDC_EDIT_ANJIE) && m_banjie==FALSE){
pDC->SetBkMode(TRANSPARENT);
pDC->SetTextColor(RGB(255,0,0));
}else if(pWnd==GetDlgItem(IDC_EDIT_ANJIEER) && m_banjieer==FALSE){
pDC->SetBkMode(TRANSPARENT);
pDC->SetTextColor(RGB(255,0,0));
} 
}
} return hbr;
}

OnCtlColor中直接
//if (nCtlColor == CTLCOLOR_DLG )
return (HBRUSH) ::CreateSolidBrush(RGB ( 255, 255, 255 ) );
