基于CFormView的打印问题？

[hyllp]

我写了个SDI的程序，选择了AppWizard 中的“Printing and Print preview ”，基类选择了CFormView，出现的问题如下：我在AppWizard 所默认生成的对话框上加上List Control,通过自己的写的程序成功的将数据在List Control显示出来了，但是当我选择“打印/打印预览”的时候，却不能够将List Control中的数据打印/打印预览出来，十万火急，希望大家帮帮忙啊！！

具体一点？

也就是说在CFormView中如何实现打印？

if (m_pBm->GetSafeHandle()) m_pBm->DeleteObject();
m_pBm->CreateCompatibleBitmap(&dc,rect.Width(),rect.Height());
m_pMemDC->SelectObject(m_pBm);
dc.DPtoLP(rect); //Convert to Logical Coordinates
m_rect = rect; //Save Logical Coordinates
m_pMemDC->BitBlt(0,0,rect.Width(),rect.Height(),&dc,0,0,SRCCOPY);

//This will prevent creation of the Memory device context
//and our Bitmap object a second time.
}
void CPrintView::OnPrint(CDC* pDC, CPrintInfo*)
{
// TODO: add code to print the controls
//The Following code scales the image based on printer resolution.
pDC->SetMapMode(MM_ANISOTROPIC);
pDC->SetWindowExt(m_pMemDC->GetDeviceCaps(LOGPIXELSX),m_pMemDC->GetDeviceCaps(LOGPIXELSY));
pDC->SetViewportExt(pDC->GetDeviceCaps(LOGPIXELSX),pDC->GetDeviceCaps(LOGPIXELSY));
pDC->StretchBlt(0,0,m_rect.Width(),m_rect.Height(),m_pMemDC,0,0,m_rect.Width(),m_rect.Height(),SRCCOPY);
