Neues Hauptfenster mit CreateNewFrame() erzeugen.

[J1M1]

Hello.

I have a Multi-Top-Level-Documents based application.

After a button click, the application should create a new main frame based on a new doc-template.

The message handler:

void CDesktopChatMessengerView::OnClicked()
{
	theApp.NewFrame();	
}

The function:

void CDesktopChatMessengerApp::NewFrame()
{
	CMultiDocTemplate* pContactDocTemplate;
	pContactDocTemplate = new CMultiDocTemplate(
		IDR_MAINFRAME,
		RUNTIME_CLASS(CDesktopChatMessengerContactDoc),
		RUNTIME_CLASS(CMainFrame),      
		RUNTIME_CLASS(CDesktopChatMessengerContactView));
	m_pDocTemplate = pContactDocTemplate;
	AddDocTemplate(pContactDocTemplate);

	CDocument* pDoc = NULL;
	CFrameWnd* pFrame = NULL;

	pDoc = m_pDocTemplate->CreateNewDocument();
	pFrame = m_pDocTemplate->CreateNewFrame(NULL, NULL);
		if (pFrame != NULL)
		{
			// Set the title, and initialize the document.
			m_pDocTemplate->SetDefaultTitle(pDoc);
			
			m_pDocTemplate->InitialUpdateFrame(pFrame, pDoc, TRUE);
		}

	pFrame->ShowWindow(SW_SHOW);
	pFrame->UpdateWindow();

        //Close login_window
	m_pMainWnd->DestroyWindow();
}

There's no error while compiling, and also no runtime errors, but the new frame is not displayed. Why?
The current main frame is closed succesfull.
