重载WM_ERASEBKGND消息
BOOL CSampleView : : OnEraseBkgnd (CDC* pDC)
{
// Create a pruple brush.
CBrush Brush (RGB (128 , 0 , 128) )

// Select the brush into the device context .
CBrush* pOldBrush = pDC—>SelcetObject (&brush)

// Get the area that needs to be erased .
CRect reClip
pDC—>GetCilpBox (&rcClip)
//Paint the area.
pDC—> PatBlt (rcClip.left , rcClip.top , rcClip.Width ( ) , rcClip.Height( ) , PATCOPY )

//Unselect brush out of device context .

在App的InitInstance()中加入：
SetDialogBkColor(RGB(x,x,x),RGB(x,x,x));

给你一贴
HBRUSH CMobileDemoDlg::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor)
{
HBRUSH hbr = CDialog::OnCtlColor(pDC, pWnd, nCtlColor);

if(nCtlColor == CTLCOLOR_LISTBOX)
{
pDC->SetBkColor(SCREEN_BK_COLOR);
return m_brBK;
}

if(nCtlColor == CTLCOLOR_STATIC)
{
switch(pWnd->GetDlgCtrlID())
{
case IDC_HEADER_TEXT:
pDC->SetBkMode(TRANSPARENT);
return m_brBK;
break;
case IDC_HEADER_LINE:
return m_brLine;
break;
}
}
CBrush brush;
brush.CreateSysColorBrush(6);///改变对话框颜色
return hbr;
}
