单文档应用程序

[阳澄居士]

我要做一个界面，单文档应用程序，去掉主菜单，做成切分窗口，左边窗口是formview类视图，在上面做一些按钮，要求，点击一个按钮，右边窗口切换一个formview类的视图窗口。切分窗口我已经做好，就是不知道如何通过按钮来切换视图

/*切换显示视图*/
void CMyGISApp::SwitchView(DWORD dwType)
{
	CView* pNewView= NULL;
	if(!m_lpDoc||!m_lpTVDoc||!m_lpVDoc)

	if(dwType == 1)
	{
		POSITION pos = m_lpDoc->GetFirstViewPosition();
		while (pos != NULL)
		{
			CView* pView =m_lpDoc->GetNextView(pos);
			if(pView->IsKindOf(RUNTIME_CLASS(CMyView1)))
			{
				pNewView = pView;
				((CMainFrame*)m_pMainWnd)->m_wndBar1.ShowWindow(SW_SHOW);
				((CMainFrame*)m_pMainWnd)->m_wndBar2.ShowWindow(SW_HIDE);
