Answer 4

我做成了一个，下面是关键代码，如果还不行，email [email protected]我把完整的程序发给你。
void CMainFrame::SwitchForm(int nFormID)
{

CView* pOldView=GetActiveView();
CView* pNewView=(CFormView*)GetDlgItem(nFormID);

if(pNewView==NULL)
{
switch(nFormID)
{

case IDD_FILE_TRANSFER:
pNewView=(CView*)new CFile_Transfer;
break;
case  IDD_ILLPC_FORM:
pNewView=(CView*)new CIllpcView;
break;
case  IDD_SCANCER:
pNewView=(CView*)new CSCAN;
break;


default:
break;
}

CCreateContext context;
context.m_pCurrentDoc=pOldView->GetDocument();
pNewView->Create(NULL,NULL,0L,CFrameWnd::rectDefault,
this,nFormID,&context);
pNewView->OnInitialUpdate();
}

    SetActiveView(pNewView);
pNewView->ShowWindow(SW_SHOW);
pOldView->ShowWindow(SW_HIDE);
    

if(pOldView->GetRuntimeClass()==RUNTIME_CLASS(CFile_Transfer))
{
pOldView->SetDlgCtrlID(IDD_FILE_TRANSFER);
}
else if(pOldView->GetRuntimeClass()==RUNTIME_CLASS(CIllpcView))
{
pOldView->SetDlgCtrlID(IDD_ILLPC_FORM);
}
else 
{
pOldView->SetDlgCtrlID(IDD_SCANCER);
}
pNewView->SetDlgCtrlID(AFX_IDW_PANE_FIRST);

RecalcLayout();
}
