高手们帮我看看为什么不能打印?

Question

下面是我在View中重载的打印函数,已经实现打印预览了.但是在打印预览中点击打印按钮却并没有出现打印提示.如果方便,哪位高手给个可以预览打印的例子,网上那几个的我已经找过了，都实现不了.
void CRegCodeMgrView::OnMyPrintPreview()
{
GetParent()->ShowWindow(SW_SHOWMAXIMIZED);
m_bPrint=FALSE;
CHHView::OnFilePrintPreview();
}
BOOL CRegCodeMgrView::OnPreparePrinting(CPrintInfo* pInfo) 
{
if(DoPreparePrinting(pInfo))
return TRUE;
else
{
GetParent()->DestroyWindow();
return FALSE;
}
}void CRegCodeMgrView::OnBeginPrinting(CDC* pDC, CPrintInfo* pInfo) 
{
CHHView::OnBeginPrinting(pDC, pInfo);
CPrintFrame *pFrame =(CPrintFrame *)GetParent();
pFrame->m_pCallerDlg->SendMessage(WM_BEGIN_PRINTING,(WPARAM) pDC, (LPARAM) pInfo);
}
void CRegCodeMgrView::OnEndPrinting(CDC* pDC, CPrintInfo* pInfo) 
{
CHHView::OnEndPrinting(pDC, pInfo);
CPrintFrame *pFrame =(CPrintFrame *)GetParent();
pFrame->m_pCallerDlg->SendMessage(WM_END_PRINTING,(WPARAM) pDC, (LPARAM) pInfo);
if(m_bPrint) //直接打印，不是预览
GetParent()->DestroyWindow();
}void CRegCodeMgrView::OnPrint(CDC* pDC, CPrintInfo* pInfo) 
{
CPrintFrame *pFrame =(CPrintFrame *)GetParent();
pFrame->m_pCallerDlg->SendMessage(WM_MY_PRINT,(WPARAM) pDC, (LPARAM) pInfo) ;
}
void CRegCodeMgrView::OnEndPrintPreview(CDC* pDC, CPrintInfo* pInfo, POINT point, CPreviewView* pView) 
{
CHHView::OnEndPrintPreview(pDC, pInfo, point, pView);
GetParent()->PostMessage (WM_CLOSE);

}

Answer 1

楼上的不一定对，但是我感觉好象m_bPrint=FALSE

Answer 2

已经试 过了，改为FALSE时打印报错!有高手给指点指点了!!!
