主要代码如下： void CPageDlg::OnPaint(){ if (IsIconic()) { CPaintDC dc(this); // device context for painting SendMessage(WM_ICONERASEBKGND, (WPARAM)dc.GetSafeHdc(), 0); // Center icon in client rectangle int cxIcon = GetSystemMetrics(SM_CX
主要代码如下：
void CPageDlg::OnPaint()
{
if (IsIconic())
{
CPaintDC dc(this); // device context for painting
SendMessage(WM_ICONERASEBKGND, (WPARAM)dc.GetSafeHdc(), 0);
// Center icon in client rectangle
int cxIcon = GetSystemMetrics(SM_CXICON);
int cyIcon = GetSystemMetrics(SM_CYICON);
CRect rect;
GetClientRect(&rect);
int x = (rect.Width() - cxIcon + 1) / 2;
int y = (rect.Height() - cyIcon + 1) / 2;
// Draw the icon
dc.DrawIcon(x, y, m_hIcon);
}
else
{
// CDialog::OnPaint(); //一定要去掉该句
CPaintDC dc(this); //对话框的dc
CDC dcMem;
dcMem.CreateCompatibleDC(&dc); //创建与对话框dc兼容的内存dc
CRect rect;
GetClientRect(&rect);
BITMAP bitMap;
m_bmpBackground.GetBitmap(&bitMap);
CBitmap *pbmpOld = dcMem.SelectObject(&m_bmpBackground); //将背景位图选入内存dc中
dc.StretchBlt(0, 0, rect.Width(), rect.Height(), &dcMem, 0, 0,
bitMap.bmWidth, bitMap.bmHeight, SRCCOPY);
//dc.BitBlt(0,0,rect.Width(),rect.Height(),&dcMem,0,0,SRCCOPY);
}
