为MFC按钮添加各种图片
一般放在重绘函数OnPaint()里
OnPaint()
{
//为按钮添加图片
Image image(L"...resSH\\退出系统正常状态.png",TRUE);
Graphics graphics(m_button16.GetWindowDC()->m_hDC);
graphics.DrawImage(&image,0,0,image.GetWidth(),image.GetHeight());
//为窗体添机背景图片
CPaintDC dc(this); // device context for painting
CRect rect;
GetClientRect(&rect);
Graphics graphics(dc.m_hDC);
//加载PNG图片
Bitmap background(L".\\userlist\\classlist_top.png");
graphics.DrawImage(&background,0,0,rect.Width(),rect.Height());
CDialog::OnPaint();
}
