BCG登錄檔清除：
第一次在CXXXApp::ExitInstance() 加入CleanState()，
執行一次
接著註釋掉，再在OnInitInstance加入m_bSaveState=FALSE
估計在BCG控制元件要寫登錄檔的時候，它自己的寫入登錄檔函式會判斷m_bSaveState

1.VC2008集成了BCGControlBar的相關功能，用wizard生成的話如果選與BCGControlBar有關的效能，如預定面板，則應用程式是從CWinAppEx派生，再加CBCGPWorkspace似乎不行。

2.BCG 為了方便程式設計師，在登錄檔中儲存了視窗的大小、位置等資訊，包括工具欄的相應資訊。這樣減少了程式設計師儲存和恢復使用者上次使用過的介面的重複勞動。但也會造成改變選單之類出現無反應的現象，讓人摸不著頭腦。可以採用的一個方法是，刪除 BCG 為你儲存的登錄檔鍵：
HKEY_CURRENT_USER/Software/[your corporation]/[your application]/Workspace
裡面 your corporation 是指在 app 類裡面 SetRegistryKey 指定的路徑；your application 就是你的應用程式名。
把這個刪掉之後，還是用你最上面的程式碼，執行。OK!

更方便的是InitInstance裡設m_bSaveState=FALSE;

如果已經有註冊內容了再加一句CleanState();

程式成型後再加上。

3.應用面板的過程
（1)找一個BCG的例子，將選單與面板相關的項複製貼上到你的選單下，ID值是連續的。

（2）CMainFrame的標頭檔案中
#define CFrameWnd CBCGPFrameWnd//類定義前。這樣可以省很多替換工作哦
UINT m_nAppLook;//指示應用哪個面板
CBCGPMenuBar m_wndMenuBar;
//手動加入訊息響應：
afx_msg void OnAppLook(UINT id);
afx_msg void OnUpdateAppLook(CCmdUI* pCmdUI);

（3）CMainFrame的Cpp檔案
//訊息對映增加
ON_COMMAND_RANGE(ID_VIEW_APPLOOK_2000, ID_VIEW_APPLOOK_VS2008, OnAppLook) //這是範圍的響應，所以ID要連續
ON_UPDATE_COMMAND_UI_RANGE(ID_VIEW_APPLOOK_2000, ID_VIEW_APPLOOK_VS2008, OnUpdateAppLook)
//初始化函式
m_nAppLook = theApp.GetInt (_T("ApplicationLook"), ID_VIEW_APPLOOK_2003);//初始的樣子
//OnCreate
OnAppLook (m_nAppLook);

if (!m_wndMenuBar.Create (this))
{
TRACE0("Failed to create menubar/n");
return -1; // fail to create
}

m_wndMenuBar.SetBarStyle(m_wndMenuBar.GetBarStyle() | CBRS_SIZE_DYNAMIC);

m_wndMenuBar.EnableDocking(CBRS_ALIGN_ANY);
EnableDocking(CBRS_ALIGN_ANY);
EnableAutoHideBars(CBRS_ALIGN_ANY);
DockControlBar(&m_wndMenuBar); //可浮動

//直接把以下兩個函式拷貝上去就OK了。
void CMainFrame::OnAppLook(UINT id)
{
CBCGPDockManager::SetDockMode (BCGP_DT_SMART);

m_nAppLook = id;

switch (m_nAppLook)
{
case ID_VIEW_APPLOOK_2000:
// enable Office 2000 look:
CBCGPVisualManager::SetDefaultManager (RUNTIME_CLASS (CBCGPVisualManager));
break;

case ID_VIEW_APPLOOK_XP:
// enable Office XP look:
CBCGPVisualManager::SetDefaultManager (RUNTIME_CLASS (CBCGPVisualManagerXP));
break;

case ID_VIEW_APPLOOK_WIN_XP:
// enable Windows XP look (in other OS Office XP look will be used):
CBCGPWinXPVisualManager::m_b3DTabsXPTheme = TRUE;
CBCGPVisualManager::SetDefaultManager (RUNTIME_CLASS (CBCGPWinXPVisualManager));
break;

case ID_VIEW_APPLOOK_2003:
// enable Office 2003 look:

CBCGPDockManager::SetDockMode (BCGP_DT_SMART);
break;

case ID_VIEW_APPLOOK_VS2005:

CBCGPVisualManager::SetDefaultManager (RUNTIME_CLASS (CBCGPVisualManagerVS2005));
CBCGPVisualManager::GetInstance ();
CBCGPDockManager::SetDockMode (BCGP_DT_SMART);
break;

case ID_VIEW_APPLOOK_VS2008:
// enable VS 2008 look:
CBCGPVisualManager::SetDefaultManager (RUNTIME_CLASS (CBCGPVisualManagerVS2008));
CBCGPVisualManager::GetInstance ();
CBCGPDockManager::SetDockMode (BCGP_DT_SMART);
break;

case ID_VIEW_APPLOOK_2007_1:
// enable Office 2007 look:

CBCGPDockManager::SetDockMode (BCGP_DT_SMART);
break;

case ID_VIEW_APPLOOK_2007_2:

CBCGPVisualManager::SetDefaultManager (RUNTIME_CLASS (CBCGPVisualManager2007));
CBCGPDockManager::SetDockMode (BCGP_DT_SMART);
break;

case ID_VIEW_APPLOOK_2007_3:

CBCGPVisualManager2007::SetStyle (CBCGPVisualManager2007::VS2007_Aqua);
CBCGPVisualManager::SetDefaultManager (RUNTIME_CLASS (CBCGPVisualManager2007));
CBCGPDockManager::SetDockMode (BCGP_DT_SMART);
break;

case ID_VIEW_APPLOOK_2007_4:
// enable Office 2007 look:
CBCGPVisualManager2007::SetStyle (CBCGPVisualManager2007::VS2007_Silver);
CBCGPVisualManager::SetDefaultManager (RUNTIME_CLASS (CBCGPVisualManager2007));
CBCGPDockManager::SetDockMode (BCGP_DT_SMART);
break;

default:
ASSERT (FALSE);
}

CBCGPDockManager* pDockManager = GetDockManager ();
if (pDockManager != NULL)
{
ASSERT_VALID (pDockManager);
pDockManager->AdjustBarFrames ();
}

RecalcLayout ();
RedrawWindow (NULL, NULL, RDW_ALLCHILDREN | RDW_INVALIDATE | RDW_UPDATENOW | RDW_ERASE);

theApp.WriteInt (_T("ApplicationLook"), m_nAppLook);
}

void CMainFrame::OnUpdateAppLook(CCmdUI* pCmdUI)
{
pCmdUI->SetRadio (m_nAppLook == pCmdUI->m_nID);
}

4.上下文選單

（1）當然是新建一個需要的上下文選單

（2）應用程式類的標頭檔案下

virtual void PreLoadState ();

Cpp檔案

void C***App::PreLoadState ()
{

GetContextMenuManager()->AddMenu (_T("My menu"), IDR_CONTEXT_MENU);//IDR_CONTEXT_MENU是選單的ID

// TODO: add another context menus here
}

（3）響應上下文選單的檢視類中增加對上下文選單訊息的響應

void C***View::OnContextMenu(CWnd* , CPoint point)
{
theApp.ShowPopupMenu (IDR_CONTEXT_MENU, point, this);
// TODO: 在此處新增訊息處理程式程式碼
}

2.

BCG例子BCGPExplorer：

1.BCG的選單、工具欄、動畫圖示和位址列

這是BCG的主要特色，也比較繁瑣。

（1）如果要支援自定義工具。

首先在String表定義入口ID：ID_TOOLS_ENTRY，與某選單項關聯。然後定義連續的ID，如ID_USER_TOOL1、ID_USER_TOOL2......。

在App下增加 EnableUserTools (ID_TOOLS_ENTRY, ID_USER_TOOL1, ID_USER_TOOL10);

（2）主要是修改CMainFrame

標頭檔案宣告

CBCGPMenuBar m_wndMenuBar;
CBCGPStatusBar m_wndStatusBar;
CBCGPToolBar m_wndToolBar;
CBCGPReBar m_wndReBar; //選單、工具欄、位址列的容器
CBCGPAnimCtrl m_wndAnimate;//動畫控制元件
CComboBoxEx m_wndAddress;//位址列

增加響應自定義工具的訊息函式OnViewCustomize

手動新增訊息響應

afx_msg LRESULT OnToolbarReset(WPARAM,LPARAM);
afx_msg LRESULT OnToolbarContextMenu(WPARAM,LPARAM);

虛擬函式virtual BOOL OnShowPopupMenu (CBCGPPopupMenu* pMenuPopup);

Cpp檔案

ON_REGISTERED_MESSAGE(BCGM_RESETTOOLBAR, OnToolbarReset)
ON_REGISTERED_MESSAGE(BCGM_TOOLBARMENU, OnToolbarContextMenu)

OnCreate（）函式

CBCGPToolBar::EnableQuickCustomization ();

CBCGPToolBar::SetSizes (CSize (28, 28), CSize (22, 22));//工具欄大小
CBCGPToolBar::SetMenuSizes (CSize (22, 22), CSize (16, 16));//工具欄中下拉選單項大小

//指定常用的工具，其它會自動收縮。每個下拉（pulldown）選單條至少要有一項
