如何在基于对话框中添加状态栏

在OnInitDialog() 加入
static UINT indicators[] =
{
ID_SEPARATOR, // status line indicator
ID_INDICATOR_CAPS,
ID_INDICATOR_NUM,
ID_INDICATOR_SCRL,
};if (!m_wndStatusBar.Create(this) ||
!m_wndStatusBar.SetIndicators(indicators1,
sizeof(indicators1)/sizeof(UINT)))
{
TRACE0("Failed to create status bar\n");
return -1; // fail to create
}
RepositionBars(AFX_IDW_CONTROLBAR_FIRST, AFX_IDW_CONTROLBAR_LAST, 0);

那又怎样使状态栏显示菜单或按钮的tooltip呢？

不行呀！
error C2065: 'm_wndStatusBar' : undeclared identifier
error C2228: left of '.Create' must have class/struct/union type
error C2228: left of '.SetIndicators' must have class/struct/union type
error C2065: 'indicators1' : undeclared identifier

//加入到OnInitDialog中
HWND hDlg=GetSafeHwnd();
HWND hStatusWindow=CreateStatusWindow(WS_CHILD|WS_VISIBLE|WS_BORDER,
TEXT("状态栏"),hDlg, NULL);
int pint[4]={110,250,300,-1};
::SendMessage(hStatusWindow,SB_SETPARTS,4,(LPARAM)pint);
::SendMessage(hStatusWindow,SB_SETTEXT,1,(LPARAM)TEXT("信息一"));
::SendMessage(hStatusWindow,SB_SETTEXT,2,(LPARAM)TEXT("信息二"));
::SendMessage(hStatusWindow,SB_SETTEXT,3,(LPARAM)TEXT("信息三"));

谢谢xuejian1999(王凯)
请问那又怎样使状态栏动态显示菜单或按钮的tooltip呢？

在谈判youdlg.h 定义
CStatusBar m_wndStatusBar;

给你一个微软的例子,你只要从CModelessMain继承一个对话框类即可

  Purpose:
Interface for CModelessMain, a reusable class for creating modeless
dialogs which act as main application windows.  The dialog contains
a status bar and a tool bar.  It provides support for ID_VIEW_STATUS_BAR
and ID_VIEW_TOOLBAR commands, as well as CAPS, NUM, and SCRL key
indicators.  Functions:
CModelessMain::CModelessMain()          -- constructor
CModelessMain::~CModelessMain()         -- destructor
CModelessMain::Create()                 -- Create dialog window
CModelessMain::GetStatusBar()           -- access status bar
CModelessMain::GetToolBar()             -- access toolbar
CModelessMain::OnClose()                -- handle WM_CLOSE
CModelessMain::OnEnterIdle()            -- handle WM_ENTERIDLE
CModelessMain::OnEraseBkgnd()           -- handle WM_ERASEBKGND
CModelessMain::OnInitDialog()           -- initialize dialog
CModelessMain::OnInitMenuPopup()        -- handle WM_INITMENUPOPUP
CModelessMain::OnMenuSelect()           -- handle WM_MENUSELECT
CModelessMain::OnPaint()                -- handle WM_PAINT
CModelessMain::OnQueryDragIcon()        -- handle WM_QUERYDRAGICON
CModelessMain::OnSetMessageString()     -- handle WM_SETMESSAGESTRING
CModelessMain::OnStatusBarCheck()       -- ID_VIEW_STATUS_BAR handler
CModelessMain::OnToolBarCheck()         -- ID_VIEW_TOOLBAR handler
CModelessMain::OnUpdateKeyIndicator()   -- update key indicator items
CModelessMain::OnUpdateStatusBarMenu()  -- update ID_VIEW_STATUS_BAR items
CModelessMain::OnUpdateToolBarMenu()    -- update ID_VIEW_TOOLBAR items  Development Team:
