AdjustLocations是CMFCToolBar的成员函数!而且百分之百肯定是在这里！
//nIndex = m_wndToolBar.CommandToIndex(ID_OBJECT_TESTTIME);
// if (nIndex >= 0)
// {
// m_wndToolBar.SetToolBarBtnText(nIndex, strTimeInfo, TRUE, TRUE);
// }
m_wndToolBar.AdjustLayout();
这样只调用AdjustLayout()有泄露！

这样时，自己重写就不会出现内存泄露，注释那两个函数！
可是工具栏就不位置还有图片文字就刷不出来了！
