本文介绍如何在MFC对话框中集成菜单、工具栏、状态栏等组件，并详细讲解了具体的实现步骤，包括创建和布局这些组件的方法。

在对话框中使用菜单、工具栏等

DlgBars解析

（1）在对话框资源中进行占位，设置相应ID，产生相应变量

CStatic m_wndMenuBarLocation;//菜单
CStatic m_wndStatusBarLocation;//状态栏
CStatic m_wndToolbarLocation;//工具栏
CStatic m_wndOutlookBarLocation;//Outlook侧边栏
CStatic m_wndCaptionLocation;//标题栏

(2)有关菜单的类

class CMyMenuBar : public CBCGPMenuBar

class CCmdFrame : public CBCGPFrameWnd

构造函数CCmdFrame(CBCGPDialog* pDlg);

BOOL CCmdFrame::OnCmdMsg(UINT nID, int nCode, void* pExtra, AFX_CMDHANDLERINFO* pHandlerInfo)
{
ASSERT_VALID (m_pDlg);
return m_pDlg->OnCmdMsg(nID, nCode, pExtra, pHandlerInfo);//转由对话框处理
}

class CMyFrameImpl : public CBCGPFrameImpl

//CBCGPFrameImpl实现工具栏的管理，包括从注册表读写状态，docking，键盘和鼠标消息等
{
CMyFrameImpl() : CBCGPFrameImpl (NULL) {}

friend class CCmdFrame;
};

void CCmdFrame::SetMenuBar (CBCGPMenuBar* pMenuBar)
{
((CMyFrameImpl&)m_Impl).m_pMenuBar = pMenuBar;//实际是把CMyMenuBar绑定到CMyFrameImpl
}

（3）对话框类

头文件

#define CDialog CBCGPDialog

定义：

CBCGPOutlookBar m_wndOutlookBar;
CBCGPOutlookBarPane m_wndPane1;
CBCGPOutlookBarPane m_wndPane2;

CMyMenuBar   m_wndMenuBar;
CBCGPCaptionBar  m_wndCaptionBar;
CBCGPToolBar  m_wndToolBar;
CBCGPStatusBar  m_wndStatusBar;

CBitmap m_bmpCaption;

CCmdFrame* m_pMenuFrame;
