1.  在资源视图中增加EditBox, Button控件，ID分别为ID_EDIT_SEED， ID_BTN_SEED

2. 在CMainFrame中增加成员变量

CMFCToolBarEditBoxButton *m_editSeed;
CMFCToolBarButton *m_btnSeed;

3. 在CMainFrame::OnCreate中创建控件

m_editSeed = new CMFCToolBarEditBoxButton(ID_EDIT_SEED, GetCmdMgr()->GetCmdImage(ID_EDIT_SEED, FALSE));
m_editSeed->EnableWindow(true);
m_editSeed->SetContents("0");
//m_editSeed->CanBeStretched();
//m_editSeed->HaveHotBorder();
//m_editSeed->SetFlatMode();
//m_editSeed->OnSize(65);
m_btnSeed = new CMFCToolBarButton(ID_BTN_SEED, GetCmdMgr()->GetCmdImage(ID_BTN_SEED, FALSE), "SEED");
m_btnSeed->EnableWindow(true);
m_btnSeed->m_bText = true;
m_btnSeed->m_strText = "NUM";

4. 增加工具栏控件替换函数

afx_msg LRESULT OnToolbarReset(WPARAM, LPARAM);ON_REGISTERED_MESSAGE(AFX_WM_RESETTOOLBAR, OnToolbarReset)LRESULT CMainFrame::OnToolbarReset(WPARAM wp, LPARAM lp)
{m_wndToolBar.ReplaceButton(ID_EDIT_SEED, *m_editSeed);m_wndToolBar.ReplaceButton(ID_BTN_SEED, *m_btnSeed);return 0;
}

5. 增加控件事件函数，否则控件没有enable

afx_msg void OnUpdateEditSeed(CCmdUI *pCmdUI);
afx_msg void OnBnClickedButtonSeed();ON_UPDATE_COMMAND_UI(ID_EDIT_SEED, &CMainFrame::OnUpdateEditSeed)
ON_BN_CLICKED(ID_BTN_SEED, &CMainFrame::OnBnClickedButtonSeed)void CMainFrame::OnUpdateEditSeed(CCmdUI *pCmdUI)
{int index = m_wndToolBar.CommandToIndex(ID_EDIT_SEED);CMFCToolBarEditBoxButton* editSeed = (CMFCToolBarEditBoxButton*)m_wndToolBar.GetButton(index);editSeed->EnableWindow(TRUE);
}void CMainFrame::OnBnClickedButtonSeed()
{}
