多文档编程，怎么可以在打开时直接显示自己创建的几个视图！拜大侠！

多文档编程，如何可以在打开时直接显示自己创建的几个视图！拜大侠！！！

这个是我用来注册的代码：
CMultiDocTemplate *pCImageViewDocTemplate = new CMultiDocTemplate(
IDR_WJ200TYPE,
RUNTIME_CLASS(CWJ200Doc), // document class
RUNTIME_CLASS(CChildFrame), // frame class
RUNTIME_CLASS(CImageView)); // view class
AddDocTemplate(pCImageViewDocTemplate);

CMultiDocTemplate *pCurveViewDocTemplate = new CMultiDocTemplate(
IDR_WJ200TYPE,
RUNTIME_CLASS(CWJ200Doc), // document class
RUNTIME_CLASS(CChildFrame), // frame class
RUNTIME_CLASS(CCurveView)); // view class
AddDocTemplate(pCurveViewDocTemplate);

CMultiDocTemplate *pCDataViewDocTemplate = new CMultiDocTemplate(
IDR_WJ200TYPE,
RUNTIME_CLASS(CWJ200Doc), // document class
RUNTIME_CLASS(CChildFrame), // frame class
RUNTIME_CLASS(CDataView)); // view class
AddDocTemplate(pCDataViewDocTemplate);

这个是我准备建立多个文档模板。。。公用一个Doc。。。

CMultiDocTemplate *pDocChiidTemplate;
pDocChiidTemplate = new CMultiDocTemplate(
IDR_WJ200TYPE,
RUNTIME_CLASS(CWJ200Doc), // document class
RUNTIME_CLASS(CChildFrame), // frame class
RUNTIME_CLASS(CCurveView)); // view class
AddDocTemplate(pDocChiidTemplate);

pDocChiidTemplate = new CMultiDocTemplate(
IDR_WJ200TYPE,
RUNTIME_CLASS(CWJ200Doc), // document class
RUNTIME_CLASS(CChildFrame), // frame class
RUNTIME_CLASS(CImageView)); // view class
AddDocTemplate(pDocChiidTemplate);

pDocChiidTemplate = new CMultiDocTemplate(
IDR_WJ200TYPE,
RUNTIME_CLASS(CWJ200Doc), // document class
RUNTIME_CLASS(CChildFrame), // frame class
RUNTIME_CLASS(CCurveView)); // view class
AddDocTemplate(pDocChiidTemplate);

上面的是我想建立一个模板，管理一个Doc, 管理多个视图，请问这么用可以吗？？？？


CMultiDocTemplate *pDocChiidTemplate;

pDocChiidTemplate = new CMultiDocTemplate(
IDR_WJ200TYPE,
RUNTIME_CLASS(CWJ200Doc), // document class
RUNTIME_CLASS(CChildFrame), // frame class
RUNTIME_CLASS(CDataView)); // view class
AddDocTemplate(pDocChiidTemplate);

POSITION pDocPosition = pDocChiidTemplate->GetFirstDocPosition();
CDocument *pd = pDocChiidTemplate->GetNextDoc(pDocPosition);

CImageView *m_Image;
CCurveView *m_Curve;

pd->AddView(m_Image);
pd->AddView(m_Curve);


这个是我想建立在一个文档模板类里面添加视图，这么做的时候pDocPosition获得不到值，这是为什么？这么做行不行


下面是我用来显示的代码：
第一段：：：：
pDocPosition = pDocChiidTemplate->GetFirstDocPosition();

while(pDocPosition != NULL)
{
CDocument *pDocument = pDocTemplate->GetNextDoc(pDocPosition);
POSITION pViewPosition = pDocument->GetFirstViewPosition();

while(pViewPosition != NULL)
{
CView * pView = pDocument->GetNextView(pViewPosition);

if (pView->IsKindOf(RUNTIME_CLASS(CCurveView))) //如果已创建此view 则设其为活动
{ 
pView->GetParentFrame()->ActivateFrame(); 
pView->UpdateWindow();
}
if (pView->IsKindOf(RUNTIME_CLASS(CImageView))) //如果已创建此view 则设其为活动
{ 
pView->GetParentFrame()->ActivateFrame();  
pView->UpdateWindow();
  }
if (pView->IsKindOf(RUNTIME_CLASS(CDataView))) //如果已创建此view 则设其为活动
{ 
pView->GetParentFrame()->ActivateFrame();  
pView->UpdateWindow();
  }
}

CMDIChildWnd *pNewFrame = (CMDIChildWnd *)pDocTemplate->CreateNewFrame(pDocument, NULL);
pDocTemplate->InitialUpdateFrame(pNewFrame, pDocument);
}


第二段：：：
pDocPosition = pCImageViewDocTemplate->GetFirstDocPosition();
while(pDocPosition != NULL)
{
CDocument *pDocument = pDocTemplate->GetNextDoc(pDocPosition);
POSITION pViewPosition = pDocument->GetFirstViewPosition();
