SDK自基建工具栏和状态栏，窗口大小改变，栏不变

SDK自建工具栏和状态栏，窗口大小改变，栏不变
用SDK自己创建工具栏和状态栏，窗口大小改变，如最大化，但是工具栏和状态栏位置不变。
求指导啊~

hStatusBar=CreateWindowEx(0L,STATUSCLASSNAME,NULL,WS_CHILD | WS_VISIBLE,//Create StatusBar
0, 0, 0, 0, m_hWnd,(HMENU)IDR_MENU1,g_hInstance,NULL);

MessageBox(m_hWnd,"StatusBar is not created!",NULL,MB_ICONERROR);
return FALSE;
}
SetStatusBar(m_hWnd);//Set Statusbar

hToolBar=CreateWindowEx(0L,TOOLBARCLASSNAME,NULL,WS_CHILD | WS_VISIBLE,//Create ToolBar
0, 0, 0, 0, m_hWnd,(HMENU)IDR_MENU1,g_hInstance,NULL);
if(NULL==hToolBar)

}
SetToolBar(m_hInstance);//Set Toolbar

SendMessage(hStatusBar, SB_SETTEXT, (WPARAM)0, (LPARAM)time.GetTime());  
  SendMessage(hStatusBar, SB_SETTEXT, (WPARAM)1, (LPARAM)TEXT("1111")); 
}

void SetToolBar(HINSTANCE m_hInstance)
{
TBBUTTON tbb[]={
{ 0, ID_FILE_NEW, TBSTATE_ENABLED, TBSTYLE_BUTTON, 0L, 0},
{ 1, ID_FILE_OPEN, TBSTATE_ENABLED, TBSTYLE_BUTTON, 0L, 0},
{ 2, ID_FILE_EXIT, TBSTATE_ENABLED, TBSTYLE_BUTTON, 0L, 0},
{ 2, 0,TBSTATE_ENABLED, TBSTYLE_SEP, 0L, -1},
{ 3, ID_DRAW_REC, TBSTATE_ENABLED, TBSTYLE_BUTTON, 0L, 0},
{ 3, 0,TBSTATE_ENABLED, TBSTYLE_SEP, 0L, -1},
{ 4, ID_HELP_ABOUT, TBSTATE_ENABLED, TBSTYLE_BUTTON, 0L, 0},
}; 
TBADDBITMAP tbBitamps;
tbBitamps.hInst=m_hInstance; // current instance
tbBitamps.nID=IDR_TOOLBAR1 ;

SendMessage(hToolBar, TB_BUTTONSTRUCTSIZE, (WPARAM)sizeof(TBBUTTON), 0);
SendMessage(hToolBar, TB_ADDBUTTONS, (WPARAM)7, (LPARAM)(LPTBBUTTON)&tbb);
SendMessage(hToolBar, TB_ADDBITMAP, 5, (LPARAM)&tbBitamps);
}

[解决办法]
WM_SIZE消息响应中计算好工具或者状态栏的显示位置，然后MoveWidow/SetWindowsPos()应该可以的
