文档视图问题，大家看看？

[zjz800800]

我做了一个单文档多视图的程序，现在默认情况下是CCargoView类和CCargoDoc关联，
现在我从CScrollView派生一个类CPrintView,请问怎么样将CPrintView和CCargoDoc进行关联

[老夏Max]

使用DocTemplate，可以找到多文档类型的程序的例子看看。
在Codeproject上有，忘了网址，你找找。
关联文档和视是通过文档模板实现的。

[zhaogaojian]

CSingleDocTemplate* pDocTemplate;
pDocTemplate = new CSingleDocTemplate(
IDR_MAINFRAME,
RUNTIME_CLASS(CGraphDoc),
RUNTIME_CLASS(CMainFrame),
RUNTIME_CLASS(CGraphView));
AddDocTemplate(pDocTemplate);
你按Instance中的这个格式写就行了

我按你说的加了但是出现下面的问题我把　#include "PrintView.h"在框架和App中都加了还是出现下面的情况

E:\Documents and Settings\zjz\桌面\Survey\Survey.cpp(93) : error C2653: 'PrintView' : is not a class or namespace name
E:\Documents and Settings\zjz\桌面\Survey\Survey.cpp(93) : error C2065: 'classPrintView1' : undeclared identifier

类CPrintView写到Survey.cpp中去

[zjz800800]

谢谢大家程序好了但这样不能满足用户的要求，程序刚启动就冒出来个对话框让选试图太难看了，大家有别的办法嘛？

[zhoujiamurong]

冒出来个对话框让选试图太难看？？？？
不懂

[tomjones_227]

在survey.cpp中添加#include "printview.h"

不要调用 AddDocTemplate(pDocTemplate);

通过调用pDocTemplate->CreateNewFrame()来创建。

[zjz800800]

CWnd* pMainWnd = AfxGetMainWnd();//0x00375760

ASSERT_VALID( pMainWnd );

if( !pMainWnd->IsKindOf( RUNTIME_CLASS( CFrameWnd ) ) )
{
return NULL;
}
return static_cast<CFrameWnd*>( pMainWnd )
->GetActiveFrame();

void EkSwitchViewInFrame(CFrameWnd* pFrame,CRuntimeClass* pViewClass )
{
ASSERT_VALID( pFrame );
ASSERT( pViewClass != NULL );

ASSERT( pViewClass->
IsDerivedFrom( RUNTIME_CLASS( CView ) ) );

// 1 - Find the currently active view
CView* pActiveView = pFrame->GetActiveView();
if( pActiveView == NULL )
{
TRACE0( "Unable to switch: no active view\n" );
return;
}

// if( pActiveView->IsKindOf( pViewClass ) )
// {
// // No need to switch for same view class
// return;
// }

// 2 - Store current view position

CRect rcView;
pActiveView->GetWindowRect( &rcView );


// 3 - Find the associated document
CDocument* pDoc = pActiveView->GetDocument();

ASSERT_VALID( pDoc );

// 4 - Make sure the document won't self-destruct
// when active view is destroyed
BOOL bSaveAutoDelete = pDoc->m_bAutoDelete;
pDoc->m_bAutoDelete = FALSE;

// 5 - Destroy the active view
pActiveView->DestroyWindow();

// 6 - Restore document to initial state
pDoc->m_bAutoDelete = bSaveAutoDelete;

// 7 - Initialize creation context used by CreateView
CCreateContext context;
context.m_pNewDocTemplate = NULL;
context.m_pLastView = NULL;
context.m_pCurrentFrame = NULL;

context.m_pNewViewClass = pViewClass;
context.m_pCurrentDoc = pDoc;

// 8 - Create the new view
CView* pNewView = static_cast<CView*>
( pFrame->CreateView( &context ) );

ASSERT_VALID( pNewView );

// 9 - Position the new view like the old one
pFrame->ScreenToClient( &rcView );
pNewView->MoveWindow( &rcView, TRUE );

// 10 - Send WM_INITIALUPDATE to the view
pFrame->InitialUpdateFrame( pDoc, TRUE );
}

我首先是将但文档窗口切分为两个窗口，左边是用CGfxOutBarCtrl作的QQ框右边是文档试图，现在只是默认情况下CCargoView类和CCargoDoc关联,我现在想让CCargoDoc和我谈出来的CPrintView关联来打印数据但是总觉得有点难办，上面是段代码大家提提意见

建议先去看一下“深入了解MFC中的文挡/视结构”这篇文章，用百度就能搜到。

好的，谢谢我搜搜
