我正在尝试向 SDI 应用程序添加多个（实际上是 3 个）视图，并让用户选择女巫视图将根据他的选择加载：
我在官方 MS 文档中遵循了本教程。因此，创建了三个类：CAdminView CAssistantView CBiblioView 和一个与对话框框架相关联的身份验证类。
我的问题是：
1）如何编辑这三个视图类（图形）？
2）第一次我想只显示身份验证对话框窗口，怎么做？
* I tried to change m_pMainWnd->ShowWindow(SW_SHOW);
by m_pMainWnd->ShowWindow(SW_HIDE); but no expected result
3）我希望根据参数加载视图，这是我添加到 InitInstance 函数中的：
CView* pActiveView = ((CFrameWnd*) m_pMainWnd)->GetActiveView();
m_BiblioView = (CView*) new CBiblioView;
m_AdminView = (CView*) new CAdminView;
m_AssistantView = (CView*) new CAssistantView;
CDocument* pCurrentDoc = ((CFrameWnd*)m_pMainWnd)->GetActiveDocument();
// Initialize a CCreateContext to point to the active document.
// With this context, the new view is added to the document
// when the view is created in CView::OnCreate().
CCreateContext newContext;
newContext.m_pNewViewClass = NULL;
newContext.m_pNewDocTemplate = NULL;
newContext.m_pLastView = NULL;
newContext.m_pCurrentFrame = NULL;
newContext.m_pCurrentDoc = pCurrentDoc;
// The ID of the initial active view is AFX_IDW_PANE_FIRST.
// Incrementing this value by one for additional views works
// in the standard document/view case but the technique cannot
// be extended for the CSplitterWnd case.
UINT viewID = AFX_IDW_PANE_FIRST + 1;
CRect rect(0, 0, 0, 0); // Gets resized later.
// Create the new view. In this example, the view persists for
// the life of the application. The application automatically
// deletes the view when the application is closed.
m_AdminView->Create(NULL, "Fenetre Administrarteur", WS_CHILD, rect, m_pMainWnd, viewID, &newContext);
m_AssistantView->Create(NULL, "Fenetre Assistant", WS_CHILD, rect, m_pMainWnd, viewID, &newContext);
m_BiblioView->Create(NULL, "Fenetre Bibliothecaire ", WS_CHILD, rect, m_pMainWnd, viewID, &newContext);
// When a document template creates a view, the WM_INITIALUPDATE
// message is sent automatically. However, this code must
// explicitly send the message, as follows.
m_AdminView->SendMessage(WM_INITIALUPDATE, 0, 0);
m_AssistantView->SendMessage(WM_INITIALUPDATE, 0, 0);
m_BiblioView->SendMessage(WM_INITIALUPDATE, 0, 0);
这是我的开关功能：
CView* CMiniProjetApp::SwitchView(int Code ) //1 : Admi / 2 : Biblio / 3 : Assistant
{
CView* pActiveView =((CFrameWnd*) m_pMainWnd)->GetActiveView();
CView* pNewView= NULL;
switch(Code){
case 1 : pNewView= m_AdminView; break;
case 2 : pNewView= m_BiblioView; break;
case 3 : pNewView= m_AssistantView; break;
}
// Exchange view window IDs so RecalcLayout() works.
#ifndef _WIN32
UINT temp = ::GetWindowWord(pActiveView->m_hWnd, GWW_ID);
::SetWindowWord(pActiveView->m_hWnd, GWW_ID, ::GetWindowWord(pNewView->m_hWnd, GWW_ID));
::SetWindowWord(pNewView->m_hWnd, GWW_ID, temp);
#else
UINT temp = ::GetWindowLong(pActiveView->m_hWnd, GWL_ID);
::SetWindowLong(pActiveView->m_hWnd, GWL_ID, ::GetWindowLong(pNewView->m_hWnd, GWL_ID));
::SetWindowLong(pNewView->m_hWnd, GWL_ID, temp);
#endif
pActiveView->ShowWindow(SW_HIDE);
pNewView->ShowWindow(SW_SHOW);
((CFrameWnd*) m_pMainWnd)->SetActiveView(pNewView);
((CFrameWnd*) m_pMainWnd)->RecalcLayout();
pNewView->Invalidate();
return pActiveView;
}
任何错误通知??!!
*请帮我 ！
谢谢 。
