关于如何在mdi程序的视中得到模板中view和doc的指针？挺难的

[minli10001]

我建立了一个view,一个doc,然后创建了一个文档模板，我在mdi程序中新建的时候打开这个视，然后我往里添加一个对话框资源，这个对话框是从CFormView继承来的，我在对话框的类中如何午到那个模板中的view和doc的指针？多谢，解决再加分。

切换视图的时候得到文档就行，下面这个函数用时：
CRuntimeClass* pNewViewClass;
pNewViewClass= RUNTIME_CLASS(CFormSettingsView);
CNetObserverDoc* doc=(CNetObserverDoc*)GetDocument();
ASSERT(doc);
if (!doc->SwitchToView(pNewViewClass))
TRACE("SwitchToView failed !!!\n");
else
TRACE("SwitchToView successful !!!\n");

BOOL CNetObserverDoc::SwitchToView(CRuntimeClass *pNewViewClass)
{
int row, col;
row=0;col=1;
CMDIFrameWnd* pMainWnd = (CMDIFrameWnd*)AfxGetMainWnd();
// Get the active MDI child window.
CMDIChildWnd* pChild = (CMDIChildWnd*)pMainWnd->MDIGetActive();
// Get the active view attached to the active MDI child window.
CView* pOldActiveView = pChild->GetActiveView();
CSplitterWnd* pSplitter = (CSplitterWnd *)pOldActiveView->GetParent();
// ASSERT(pSplitter->IsChildPane(pOldActiveView, row, col));


pOldActiveView=(CView*)pSplitter->GetPane(row,col);
// If we're already displaying this kind of view, no need to go further.
if (pOldActiveView->IsKindOf(pNewViewClass))
return TRUE;

CRect viewrect;
pOldActiveView->GetWindowRect(&viewrect);

// set flag so that document will not be deleted when view is destroyed


m_bAutoDelete = FALSE;
// Delete existing view
pOldActiveView->DestroyWindow();
// pOldActiveView->
m_bAutoDelete=TRUE;

// set flag back to default




// Create new view
CCreateContext context;
context.m_pNewViewClass = pNewViewClass;
context.m_pCurrentDoc = this;

// POSITION pos=::AfxGetApp()->GetFirstDocTemplatePosition();

context.m_pNewDocTemplate =this->GetDocTemplate();// ::AfxGetApp()->GetNextDocTemplate(pos);
context.m_pLastView = NULL;
context.m_pCurrentFrame = NULL;
if (!pSplitter->CreateView(row, col, pNewViewClass, viewrect.Size(),
&context))
return FALSE;
CView* pNewView = (CView *)pSplitter->GetPane(row, col);
pNewView->OnInitialUpdate();
// Set active

pSplitter->GetParentFrame()->SetActiveView(pNewView);

pSplitter->RecalcLayout();
pNewView->SendMessage(WM_PAINT);
return TRUE;
}
在Form视图中得到文档：CNetObserverDoc *pNDoc=(CNetObserverDoc *)GetDocument();

在CMainFrame响应命令消息打开对话框的话，
CMDIFrameWnd *pFrame = (CMDIFrameWnd*)AfxGetApp()->m_pMainWnd;

// Get the active MDI child window.
CMDIChildWnd *pChild = (CMDIChildWnd *) pFrame->GetActiveFrame();
CMyView *pView = (CMyView *) pChild->GetActiveView();

在构造对话框时将这个指针传递给对话框。如CMyDialog dlg(pView);
