EVC下打印的问题

yunfei1019 2009-5-18 14:47 楼主

我用EVC新建了个单文档带打印功能的工程。想实现直接打印的功能，也就是说在直接按一下打印按钮就可以打印了，不弹出设置的对话框。代码如下。。。

// documentView.cpp : implementation of the CDocumentView class
//
#include "stdafx.h"
#include "document.h"
#include "documentDoc.h"
#include "documentView.h"
#ifdef _DEBUG
#define new DEBUG_NEW
#undef THIS_FILE
static char THIS_FILE[] = __FILE__;
#endif
/////////////////////////////////////////////////////////////////////////////
// CDocumentView
IMPLEMENT_DYNCREATE(CDocumentView, CEditView)
BEGIN_MESSAGE_MAP(CDocumentView, CEditView)
//{{AFX_MSG_MAP(CDocumentView)
// NOTE - the ClassWizard will add and remove mapping macros here.
// DO NOT EDIT what you see in these blocks of generated code!
//}}AFX_MSG_MAP
// Standard printing commands
ON_COMMAND(ID_FILE_PRINT, CEditView::OnFilePrint)
END_MESSAGE_MAP()
/////////////////////////////////////////////////////////////////////////////
// CDocumentView construction/destruction
CDocumentView::CDocumentView()
{
// TODO: add construction code here
}
CDocumentView::~CDocumentView()
{
}
BOOL CDocumentView::PreCreateWindow(CREATESTRUCT& cs)
{
// TODO: Modify the Window class or styles here by modifying
// the CREATESTRUCT cs
BOOL bPreCreated = CEditView::PreCreateWindow(cs);
cs.style &= ~(ES_AUTOHSCROLL|WS_HSCROLL); // Enable word-wrapping
return bPreCreated;
}
/////////////////////////////////////////////////////////////////////////////
// CDocumentView drawing
void CDocumentView::OnDraw(CDC* pDC)
{
CDocumentDoc* pDoc = GetDocument();
ASSERT_VALID(pDoc);
// TODO: add draw code for native data here
}
/////////////////////////////////////////////////////////////////////////////
// CDocumentView printing
BOOL CDocumentView::OnPreparePrinting(CPrintInfo* pInfo)
{
// default CEditView_WCE preparation
[color=#FF0000]pInfo->m_bDirect=TRUE;[/color]
return DoPreparePrinting(pInfo);
}
void CDocumentView::OnBeginPrinting(CDC* pDC, CPrintInfo* pInfo)
{
// Default CEditView_WCE begin printing.
CEditView::OnBeginPrinting(pDC, pInfo);
}
void CDocumentView::OnEndPrinting(CDC* pDC, CPrintInfo* pInfo)
{
// Default CEditView_WCE end printing
CEditView::OnEndPrinting(pDC, pInfo);
}
/////////////////////////////////////////////////////////////////////////////
// CDocumentView diagnostics
#ifdef _DEBUG
void CDocumentView::AssertValid() const
{
CEditView::AssertValid();
}
void CDocumentView::Dump(CDumpContext& dc) const
{
CEditView::Dump(dc);
}
CDocumentDoc* CDocumentView::GetDocument() // non-debug version is inline
{
ASSERT(m_pDocument->IsKindOf(RUNTIME_CLASS(CDocumentDoc)));
return (CDocumentDoc*)m_pDocument;
}
#endif //_DEBUG
/////////////////////////////////////////////////////////////////////////////
// CDocumentView message handlers

但是老是提示
D:\test\document\documentView.cpp(73) : error C2039: 'm_bDirect' : is not a member of 'CPrintInfo'

请问是什么问题，或者有什么解决办法？？谢谢大家栏

从 MFC 3.0 升级到 8.0 后不受支持的 eVC 类的列表

CPrintInfo Members

evc不支持CPrintInfo 的成员

你在这个函数中自己加一个可控的全局变量吧

BOOL CDocumentView::OnPreparePrinting(CPrintInfo* pInfo)
{
// default CEditView_WCE preparation
pInfo->m_bDirect=TRUE;替换掉它
return DoPreparePrinting(pInfo);
}
